Phase Outline Skill

Role: Two-track workflow skill for creating solution outlines. Routes based on track selection from phase-2-refine.

Prerequisite: Request must be refined (phase-2-refine completed) with track field set.

Foundational Practices

Skill: plan-marshall:dev-agent-behavior-rules

Enforcement

Shared lifecycle patterns: See phase-lifecycle.md for entry protocol, completion protocol, and error handling convention.

Execution mode: Follow workflow steps sequentially. Each step that invokes a script has an explicit bash code block.

Prohibited actions:

Never access .plan/ files directly — all access must go through python3 .plan/execute-script.py manage-* scripts
Never skip the phase transition — use manage-status transition
Never improvise script subcommands — use only those documented below
Never fall back to simple track if complex track fails — return error
Never mutate source files outside .plan/local/plans/{plan_id}/ during outline. The outline phase is strictly analytical: it discovers, classifies, and writes solution documents into the plan workspace. Edits to any path under marketplace/, target/, .claude/, test/, doc/, or any other repository directory are categorically forbidden — those mutations are the responsibility of phase-5-execute. If a recipe or domain workflow proposes a fix, capture it as a deliverable in solution_outline.md rather than applying it directly.
Never invoke any *-doctor tool (e.g., plugin-doctor, plan-doctor) carrying fix, apply, --apply, or --fix during outline. Doctor tools may only be invoked in their read-only modes (verify, check, no flags) to surface findings. The apply/fix/--fix/--apply surfaces mutate source files and bypass the per-plan workspace boundary above — they are reserved for phase-5-execute task bodies that the planner explicitly authorized via a deliverable. This applies equally to Bash, Skill:, and SlashCommand: invocation shapes.

Constraints:

Strictly comply with all rules from dev-agent-behavior-rules, especially tool usage and workflow step discipline

Dispatched workflows vs inline steps

This phase dispatches under one role key: phase-3-outline (resolves through phase-3-outline.default; track={simple|complex} is a runtime input — both tracks share the envelope and resolver lookup). The Complex Track bundles Steps 9c (per-deliverable design-intent classification), 10 (the heavyweight design body), and 10b (self-modifying classification) into one phase-3-outline envelope — the per-deliverable loop iterates inside the dispatch. Mechanical sub-procedures stay inline: Step 4 detect-change-type uses manage-status:change-type-heuristic (heuristic-first, dispatches via effort read --default when ambiguous); Simple Track Step 6 target validation is a Bash one-liner; Complex Track Step 9 domain-resolution and Step 10b consumer-sweep run as scripts. Step 11 Q-Gate validation activation is signaled by setting qgate_validation_required: true in the phase return TOON; the orchestrator (plan-marshall:plan-marshall/workflow/planning-outline.md) reads that flag and issues q-gate-validation as a sibling top-level Task: plan-marshall:{target} dispatch — the phase body cannot spawn it directly because the Task tool is unavailable inside an execution-context-{level} subagent. The flag is set to false (no orchestrator dispatch) when the surgical-bypass predicate holds (scope_estimate == surgical AND change_type ∈ {bug_fix, tech_debt, verification} AND deliverable_count == 1). For the rationale see dispatch-granularity.md § 3–4 (bundle when steps share context; per-iteration only when models differ or parallel).

Loop-invariant inputs (cached at phase entry)

The Complex Track per-deliverable loop (Steps 9c + 10 + 10b) iterates over the deliverable list — but the inputs feeding the per-deliverable design body are loop-invariant: they are written before the loop begins (phase-2-refine, phase-3-outline entry, Step 9 domain-resolution) and are not mutated by the loop body. The dispatched agent MUST read each of the following inputs ONCE at phase entry and reference the cached values throughout every per-deliverable iteration:

The clarified request narrative (read via manage-plan-documents read --plan-id {plan_id} --document request).
domains and compatibility (read via manage-files read --plan-id {plan_id} --file references.json).
module_mapping.toon if present at .plan/local/plans/{plan_id}/module_mapping.toon.
The architecture topology (read via manage-architecture topology at phase entry).
The resolved domain outline skill notation (resolved once via Step 9 domain-resolution).

Prohibited actions:

Never re-read loop-invariant inputs inside the per-deliverable loop body — re-reading inside the loop is envelope-cost waste; resolve all invariant inputs before the loop begins.

See extension-api/standards/dispatch-granularity.md § 5.1 (Heuristic 2 — bundle when steps share context) for the granularity rationale.

cwd for `.plan/execute-script.py` calls

manage-* scripts resolve .plan/ via the uniform cwd walk-up (ADR-002) — the nearest ancestor of cwd containing .plan/local. Phase-3-outline runs on the main checkout, so they resolve to main's .plan/; do NOT pin cwd, do NOT pass routing flags, and never use env -C. Build / CI / Sonar scripts accept --plan-id {plan_id} (preferred — auto-resolves the worktree via manage-status get-worktree-path) or --project-dir {worktree_path} (explicit override / escape hatch); the two flags are mutually exclusive. See plan-marshall:tools-script-executor/standards/cwd-policy.md.

Exit-code convention for `manage-*` script calls

Every manage-* script call documented below carries the following exit-code contract unless a step explicitly states otherwise:

exit_code == 0: parse the returned TOON and use the value as the step describes. exit 0 does NOT imply the operation succeeded — the manage-* scripts follow the canonical output contract (pm-plugin-development:plugin-script-architecture/standards/output-contract.md), under which an operation failure (file_not_found, field_not_found, plan_not_found, validation rejection, already-exists, etc.) exits 0 and carries the verdict in the stdout TOON status: error payload. Branch on the TOON status / value field to detect operation failures; never infer "the field was present" or "the plan exists" from a zero exit code.
exit_code != 0: STOP the phase and return an error TOON to the orchestrator carrying the script's stderr verbatim. A non-zero exit is reserved for a genuine script crash (exit 1 — uncaught exception, corrupt/non-dict payload, missing required file) or an argparse_rejection (exit 2 — silent swallowing of wrong_parameters rejections is the prohibited anti-pattern). The phase MUST NOT proceed on a non-zero exit; "log and continue" is equally forbidden.

Step-level exceptions to this default — calls whose non-zero exit is itself the signal (e.g., manage-files exists returning exists: false, or manage-status get-worktree-path returning an empty worktree_path) — are documented inline in the step that issues them. Treat the absence of an inline exception as the default "hard-stop" behaviour above.

Operation-failure carve-out (manage-* read verbs): Because operation failures exit 0, a step that reads a manage-* read verb (get, read, get-context, set-list, and the like) to discover whether a field/plan/file is present MUST detect the not-found / validation outcome by inspecting the TOON status (status: error plus the precise error code) — NOT by testing exit_code != 0. Reserving exit_code != 0 for crash/argparse detection and reading the TOON for operation-failure detection are two distinct branches; conflating them (treating any non-zero exit as "field absent") regresses the contract and is forbidden.

Phase-Entry Worktree Assertion

The Phase Entry Protocol's phase_handshake verify --phase 2-refine --strict call (see ref-workflow-architecture/standards/phase-lifecycle.md) asserts the tri-state worktree-resolution contract before any phase-3-outline work begins. When metadata.use_worktree==true AND metadata.worktree_path is empty, the assertion treats this as the deferred-materialization window and passes — phases 2-3-4 run on the main checkout / current feature-branch intent until phase-5-execute Step 2.5 materializes the artifacts. The strict path-not-found / path-stale failures still fire when worktree_path is set but does not resolve cleanly. Phases 5-6 retain the original strict semantics. Plans with metadata.use_worktree==false skip the assertion (main-checkout flow). See workflow-integration-git/standards/worktree-handling.md for the canonical lifecycle contract and the underlying _resolve_worktree_assertion implementation in phase_handshake.py.

Workflow Overview

Step 2: Load Inputs → Step 3: Recipe Detection → Step 4: Detect Change Type → Step 5: Route by Track → {Simple: Steps 6-8 | Complex: Steps 9-11} → Step 12: Return

Step 1: Check for Unresolved Q-Gate Findings

Purpose: On re-entry (after Q-Gate or user review flagged issues), address unresolved findings before re-running the outline.

Query pending findings for phase 3-outline. For each finding: analyze context, verify file paths exist on disk, create assessments or update deliverables as needed, then resolve the finding with taken_into_account. Continue with normal Steps 2..12 after corrections are applied. When a finding scopes to one peer of a symmetric data structure (ladder, parallel-array, peer-set, matrix), apply the symmetric-peer-audit rule: audit every peer in the same structure for the same defect and apply the same fix in the same outline revision — see standards/outline-workflow-detail.md § symmetric-peer-audit.

For detailed procedures (query commands, finding-type handling, resolution logging), see standards/outline-workflow-detail.md.

Step 2: Load Inputs

Purpose: Load track, request, compatibility, and context from phase-2-refine output and sinks.

Note: This skill receives track, track_reasoning, scope_estimate, compatibility, and compatibility_description from the phase-2-refine return output. These values are passed as input parameters.

Receive Track from Phase-2-Refine Output

The track value (simple | complex) is received from the phase-2-refine return output, not read from references.json.

If track not provided in input, extract from decision.log:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  read --plan-id {plan_id} --type decision | grep "(plan-marshall:phase-2-refine) Track:"

Parse the output to extract track value from: (plan-marshall:phase-2-refine) Track: {track} - {reasoning}

Read Request

Read request (clarified_request falls back to original_input automatically):

python3 .plan/execute-script.py plan-marshall:manage-plan-documents:manage-plan-documents request read \
  --plan-id {plan_id} \
  --section clarified_request

Read Module Mapping (optional)

Check existence first (file is created by phase-2-refine and may not exist):

python3 .plan/execute-script.py plan-marshall:manage-files:manage-files exists \
  --plan-id {plan_id} \
  --file work/module_mapping.toon

If exists: true, read it:

python3 .plan/execute-script.py plan-marshall:manage-files:manage-files read \
  --plan-id {plan_id} \
  --file work/module_mapping.toon

If exists: false, continue without module mapping — downstream steps will use discovery or request context instead.

Read Domains

python3 .plan/execute-script.py plan-marshall:manage-references:manage-references get \
  --plan-id {plan_id} --field domains

Receive Compatibility from Phase-2-Refine Output

The compatibility and compatibility_description values are received from the phase-2-refine return output.

If compatibility not provided in input, read from marshal.json:

python3 .plan/execute-script.py plan-marshall:manage-config:manage-config \
  plan phase-2-refine get --field compatibility --audit-plan-id {plan_id}

Store as compatibility and derive compatibility_description from the value:

breaking → "Clean-slate approach, no deprecation nor transitionary comments"
deprecation → "Add deprecation markers to old code, provide migration path"
smart_and_ask → "Assess impact and ask user when backward compatibility is uncertain"

Receive Simplicity from Phase-2-Refine Output

The simplicity and simplicity_description values are received from the phase-2-refine return output.

If simplicity not provided in input, read from marshal.json (default lean when unconfigured):

python3 .plan/execute-script.py plan-marshall:manage-config:manage-config \
  plan phase-2-refine get --field simplicity --audit-plan-id {plan_id}

Store as simplicity and derive simplicity_description from the value:

lean → "Implement the strict minimum; remove or inline surplus structure"
pragmatic → "Prefer minimal, but keep low-risk structure that aids readability"
defensive → "Retain belt-and-suspenders structure (guards, abstraction seams) where uncertain"

Log Context (to work.log - status, not decision)

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  work --plan-id {plan_id} --level INFO --message "[STATUS] (plan-marshall:phase-3-outline) Starting outline: track={track}, domains={domains}, compatibility={compatibility}"

Step 3: Recipe Detection

Purpose: Recipe-sourced plans skip change-type detection and use the recipe skill directly for discovery, analysis, and deliverable creation.

Check plan_source metadata. If recipe: read recipe metadata (recipe_key, recipe_skill, and built-in-only fields), resolve default_change_type from recipe config, load the recipe skill with input parameters, then skip Steps 4-11 and jump directly to Step 12. Recipe deliverables are deterministic architecture-to-deliverable mappings — Q-Gate is skipped.

If plan_source != recipe or field not found: continue with normal Step 4.

For detailed procedures (metadata reads, recipe resolution, skill loading), see standards/outline-workflow-detail.md.

Step 4: Detect Change Type

Purpose: Determine the change type for agent routing.

Run the deterministic classifier first; only dispatch the LLM workflow on the ambiguous branch.

Step 4a — Heuristic classifier (deterministic, no envelope):

python3 .plan/execute-script.py plan-marshall:manage-status:manage-status \
  change-type-heuristic --plan-id {plan_id} --persist

The script reads clarified_request (falling back to original_input) from request.md, scores it against the fixed keyword tables, applies the compound-intent guard and the bug-fix-vs-tech-debt object disambiguation, and either:

returns one of feature / bug_fix / tech_debt / enhancement / verification / analysis with ambiguous=false (and persists to status.metadata.change_type with --persist), OR
returns ambiguous=true when no keyword fires, the top two scores tie, or confidence falls below 0.7.

Step 4b — LLM fallback (only when ambiguous=true):

Dispatch the detect-change-type workflow (plan-marshall:phase-3-outline/workflow/detect-change-type.md via execution-context-{level} resolved from effort). The workflow persists change_type to status.json metadata itself. Skip this dispatch when Step 4a resolved without ambiguity — the heuristic already wrote the value.

For detailed procedures (agent spawning, metadata read, post-check override logic), see standards/outline-workflow-detail.md.

Step 5: Route by Track

Based on track from Step 2:

If track == simple → go to Step 6. If track == complex → go to Step 9.

Simple Track (Steps 6-8)

For localized changes where targets are already known from module_mapping.

Step	Purpose	Key Action
6. Validate Targets	Verify target files/modules exist	`ls -la {target_path}` for each target
7. Create Deliverables	Map module_mapping to deliverables	MUST classify each deliverable's `affected_files` against the File-type classifier (six buckets: `production_only` / `test_only` / `documentation_only` / `mixed_code` / `mixed_with_docs` / `unknown`) BEFORE assigning `profiles[]`. For any deliverable that touches an existing skill, MUST also run the Step 9c design-intent classification and emit the resulting `Design notes:` block — this is track-agnostic and applies on the Simple Track too, so the deliverable self-satisfies §2.17 (Architecture-Mismatch) on the first validation pass. Use deliverable template, resolve verification commands via `architecture resolve`. The resolved bucket MUST be recorded as a comment in the `Profiles:` block (see Deliverable Template below).
8. Simple Q-Gate	Lightweight verification (with surgical bypass)	Bypass when surgical+bug_fix/tech_debt/verification+1 deliverable; otherwise check target existence + request alignment

File-type classifier (normative)

Before assigning profiles[] to any deliverable, every author MUST classify the deliverable's **Affected files:** list against the six-bucket file-type classifier. The buckets, predicates, profile assignments, and verification commands are documented in standards/outline-workflow-detail.md § File-type classifier. The rule is normative — assigning module_testing to a documentation_only deliverable is a contract violation that phase-4-plan refuses to translate into a paired pytest task and instead emits a Q-Gate finding back to this phase. The aggregator that produces the bucket lives in manage-execution-manifest._classify_paths_via_extensions; per-domain predicates are owned by each bundle's ExtensionBase.classify_paths() override.

The canonical doctor invocation cited in all documentation_only deliverable Verification fields is pm-plugin-development:plugin-doctor:doctor-marketplace scan --paths {skill-dir} (NOT the stale :plugin-doctor:plugin-doctor).

Value-change test-sweep rule (normative)

This rule is track-agnostic — it applies to deliverable authoring on both the Simple Track (Step 7) and the Complex Track (Step 10).

When a deliverable changes a default value, a constant, or an enum member, the author MUST identify and enumerate every existing test that asserts the old value, add those test files to the deliverable's **Affected files:**, and describe the required test update in **Change per file:**. The existing-test sweep is a first-class part of the deliverable — it is NOT deferred to any new test file the plan introduces.

To enumerate the affected tests, sweep the test tree by identifier first, literal value only as a fallback:

Identifier-first search (primary) — search for the constant, enum-member, or default's name with a word-boundary anchor, not its value: Grep with \b{identifier}\b (or architecture find --pattern '*{identifier}*' for the structured inventory) across test/. Anchoring on the symbol name finds every test that references the changed member regardless of how it asserts the value, and the word boundary prevents substring false hits (e.g. MAX matching MAX_RETRIES).
Literal-value search (fallback only) — search for the old literal value solely when the identifier-first sweep yields nothing (e.g. the value is asserted inline with no named reference). When falling back to a literal, anchor on a word boundary and never sweep bare common literals (False, True, 0, 1, None, "") on their own — they produce overwhelming false positives. Pair the literal with the surrounding assertion or key context (e.g. {field_name}.*1) to keep the match precise.

The deliverable's resolved file-type bucket reflects the added test files: a documentation_only or production_only deliverable that now enumerates existing tests becomes mixed_code (production + test) or test_only, so module_testing becomes a valid profile per the File-type classifier.

The downstream phase-4-plan value-change rule carries these enumerated existing-test targets into the module_testing task's steps[] and anchors the obligation into the task description, so the executing agent updates every existing test asserting the old value.

Step 6 may also refine scope_estimate: After deliverables crystalize and the concrete Affected files lists are known, phase-3-outline MAY downgrade scope_estimate (e.g., single_module → surgical) when the final deliverable composition narrows the actual scope. Persist any change via manage-references set --field scope_estimate. Refinement happens BEFORE Step 8 so the bypass rule sees the refined value.

Coverage contract: deliverable composition is where a per-deliverable scope × thoroughness cell would be declared — scope_estimate is the scope dial; thoroughness (coverage breadth + relation-tracing depth) is its orthogonal partner. The coupling constraint reject thoroughness ≥ T4 ∧ scope < component means a relation-tracing deliverable forces scope ≥ component. See the two-dial ladders, the grade-to-the-floor rule, and the coupling constraint in dev-agent-behavior-rules/standards/thoroughness.md.

Step 8 — Q-Gate surgical bypass rule (evaluated BEFORE dispatching the lightweight Q-Gate checks):

Bypass Q-Gate when ALL of the following are true:

scope_estimate == surgical, AND
change_type ∈ {bug_fix, tech_debt, verification}, AND
deliverable_count == 1 (exactly one deliverable was created in Step 7)

When bypass fires, log the decision and skip directly to Step 12:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  decision --plan-id {plan_id} --level INFO --message "(plan-marshall:phase-3-outline:qgate-bypass) Q-Gate skipped — scope_estimate=surgical, change_type={change_type}, 1 deliverable"

Otherwise, run the Simple Q-Gate checks documented in the detail standards. After Step 8, proceed to Step 12.

For detailed procedures (validation commands, deliverable template, verification resolution, Q-Gate checks, bypass rule examples), see standards/outline-workflow-detail.md.

Complex Track (Steps 9-11)

For codebase-wide changes requiring discovery and analysis.

Step	Purpose	Key Action
9. Resolve Domain Skill	Route to domain-specific or generic instructions	`resolve-outline-skill --domain {domain}`, then load `change-{change_type}.md`
9c. Read Target Skill Design Intent (track-agnostic — also runs from Simple Track Step 7)	For each deliverable that touches an existing skill, classify the skill's design model and record it on the deliverable	Read the target skill's `SKILL.md` and design-intent docs; classify as `script-deterministic`, `LLM-driven`, or `hybrid`; record the classification in the deliverable's `Design notes:` block; reroute or justify when the proposed implementation contradicts the model. This classification is NOT Complex-Track-only — the Simple Track runs the same procedure from Step 7 when a deliverable touches an existing skill, so the resulting `Design notes:` block lets the deliverable self-satisfy §2.17 on the first pass. Detailed procedure: `standards/outline-workflow-detail.md`.
10. Execute Workflow	Run discovery, analysis, write solution	Follow change-type instructions, resolve verification commands, write `solution_outline.md`. For each composed deliverable, MUST apply the File-type classifier to its `affected_files` BEFORE assigning `profiles[]` — the resolved bucket MUST be recorded as a comment in the `Profiles:` block (see Deliverable Template below). Step 10 includes a consumer-sweep when the deliverable deletes/renames a public symbol — see `consumer-sweep.md`.
10b. Self-Modifying Classification	Classify deliverables that touch plan-marshall runtime infrastructure and surface phasing decision	When predicate fires (path heuristic + `compatibility: breaking` + hard-cutover language), prompt author via `AskUserQuestion` for split / inline-rationale / additive-mode resolution. Standard: `ref-workflow-architecture/standards/self-modifying-classification.md`.
11. Q-Gate Verification	Signal q-gate-validation requirement (with surgical bypass)	Bypass when surgical+bug_fix/tech_debt/verification+1 deliverable → set `qgate_validation_required: false`; otherwise set `qgate_validation_required: true` in the return TOON so the orchestrator dispatches `plan-marshall:plan-marshall/workflow/q-gate-validation.md` as a sibling top-level Task after the phase returns (see `standards/outline-workflow-detail.md` for the activation contract). The orchestrator-dispatched workflow runs phase-3-applicable validators: existing checks 2.1-2.7, consumer-sweep §2.9, argparse-validator §2.10, tier-delta-validator §2.13, self-modifying-phased-rollout-validator §2.16, architecture-mismatch-validator §2.17.

Step 10 deliverable authoring MUST apply the Value-change test-sweep rule: any deliverable that changes a default value, constant, or enum member enumerates every existing test asserting the old value into its **Affected files:**.

Step 10 may also refine scope_estimate: After Complex Track discovery and deliverable composition, the concrete Affected files lists may narrow the actual scope. Phase-3-outline MAY downgrade scope_estimate (e.g., multi_module → single_module, or single_module → surgical) and persist via manage-references set --field scope_estimate. Refinement happens BEFORE Step 11 so the bypass rule sees the refined value.

Step 11 — Q-Gate surgical bypass rule (evaluated BEFORE signaling the Q-Gate validation requirement):

Bypass Q-Gate when ALL of the following are true:

scope_estimate == surgical, AND
change_type ∈ {bug_fix, tech_debt, verification}, AND
deliverable_count == 1 (exactly one deliverable was created in Step 10)

When bypass fires, log the decision, set qgate_validation_required: false in the return TOON, and skip directly to Step 12:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  decision --plan-id {plan_id} --level INFO --message "(plan-marshall:phase-3-outline:qgate-bypass) Q-Gate skipped — scope_estimate=surgical, change_type={change_type}, 1 deliverable"

Otherwise, set qgate_validation_required: true in the return TOON. The orchestrator (plan-marshall:plan-marshall/workflow/planning-outline.md) reads that flag after the phase returns and dispatches plan-marshall:plan-marshall/workflow/q-gate-validation.md as a sibling top-level Task. The orchestrator aggregates the validator's qgate_pending_count into the phase's running count before re-evaluating the existing 3-iteration auto-loop predicate.

Special-deliverable-class recognition rules (track-agnostic, thin)

Four deliverable classes carry a recurring engineering hazard that the outline MUST recognize at authoring time and route to its canonical home. These rules fire on both tracks — Simple Track Step 7 and Complex Track Step 10 — when a deliverable being authored matches the trigger. They are recognition triggers ONLY: the substance (mitigation menu, enumeration procedure, decision checklist, field-declaration semantics) lives once in its canonical home — a dev-general-* standard, or this skill's detail standard for the clean-break and survey-scope rules — and MUST NOT be restated here or in the deliverable.

Cooperative-lock deliverable class — Trigger: the deliverable's narrative introduces or modifies a cooperative cross-process lock or shared-state coordination primitive (merge locks, worktree allocation, plan-id reservation, leader election, any "claim a shared resource" flow). Required authoring action: emit a **Concurrency-correctness note:** block on the deliverable that names the check-then-act / TOCTOU window and points to the chosen mitigation. The note MUST cross-reference the TOCTOU / check-then-act mitigation menu in dev-general-code-quality/standards/code-organization.md — do NOT duplicate the mitigation menu.
Value-change deliverable class — Trigger: the deliverable changes a default value, constant, or enum member that tests may assert against. Required authoring action: scope the old-value test assertions into the deliverable's **Affected files:** so the production change and its test-consumer updates form one atomic deliverable. The note MUST cross-reference the enumeration discipline in dev-general-module-testing/standards/testing-methodology.md — do NOT duplicate the enumeration procedure.
Clean-break vs migration-shim deliverable class — Trigger: the deliverable's narrative (Change per file: / Refactoring: / summary) removes an internal code path — a function, method, parameter, branch, or script notation that is NOT a published cross-bundle public surface. Required authoring action: apply the four-condition clean-break checklist — (1) are all callers of the removed path in-plan? (2) is there no external / cross-bundle consumer? (3) can the removal land atomically in a single PR? (4) are the old-path tests removed or rewritten in the same plan? — and choose the shape: prefer the clean-break shape (remove the path outright, no shim) when ALL four conditions hold; otherwise default to a deprecation shim with a documented removal window. Cross-reference the checklist body, per-condition rationale, and the clean-break-vs-shim decision table in standards/outline-workflow-detail.md — do NOT duplicate the checklist here or on the deliverable.
Survey-scope deliverable class — Trigger: the deliverable's description mentions survey, discover, classify, or case-by-case (a discovery-style deliverable whose exact mutation set is not fully known at authoring time). Required authoring action: declare two disjoint fields on the deliverable — **Files to survey:** (the candidate-pool / analysis scope) and **Files expected to mutate:** (the mutation-scope upper bound) — and note that the retrospective affected_files_recall check runs against the expected-to-mutate subset, NOT the survey scope. Cross-reference the field semantics, the worked example, and the survey_vs_mutation_scope_declared outline check in standards/outline-workflow-detail.md — do NOT restate the field semantics or the check here.

The matching trigger predicates and authoring actions are documented as track-agnostic siblings to the Step 9c / Step 10b procedures in standards/outline-workflow-detail.md.

Retrospective-lesson recognition rule (track-agnostic, thin)

When a plan or deliverable originates from a retrospective lesson — a lesson whose corrective fix has already shipped, but whose body carries a forward-looking / ## Generalisation rule, with the target component source still editable — the outline MUST emit the apply-the-wisdom / documentation-port shape: a documentation_only deliverable that lifts the forward-looking rule into the component's canonical docs (its SKILL.md or a standards/*.md) and cross-references the originating lesson. Do NOT emit a code-change deliverable that re-applies the already-shipped fix — the fix is done; the lesson's residual value is the generalizable wisdom.

This rule fires on both tracks. The retrospective-vs-prospective signals, the documentation-port deliverable template, and the required lesson cross-reference are defined once in standards/outline-workflow-detail.md § Retrospective-vs-prospective lesson classification — the same shared definition recipe-lesson-cleanup Step 2c consumes (the two skills stay in lockstep by reading one source). Do NOT restate the signals or the template here.

CRITICAL: If Complex Track skill workflow fails, do NOT fall back to grep/search. Fail clearly.

Domain-specific ext-outline-workflow skills MUST emit **Intent gloss:** per the deliverable template when a deliverable title contains a compound word whose head morpheme is a planning-domain verb (review, check, validate, approve, merge, …). The gloss is a single sentence (≤15 words) that restates the deliverable's goal using the tail morpheme's meaning, and phase-4-plan copies it verbatim into every derived task.description.

For detailed procedures (skill resolution, change-type loading, solution writing, Q-Gate agent interaction), see standards/outline-workflow-detail.md.

Step 12: Write Solution and Return

Deliverable Template (inline reference)

Each deliverable in solution_outline.md MUST follow this field order. The authoritative schema is in manage-solution-outline/templates/deliverable-template.md:

### {N}. {Deliverable Title}

**Metadata:**
- change_type: {feature|enhancement|tech_debt|bug_fix|analysis|verification}
- execution_mode: {automated|manual|mixed}
- domain: {domain}
- module: {module}
- depends: {none|N|N,M}

**Intent gloss:** {one-sentence disambiguation, max ~15 words — required when title head morpheme is a planning-domain verb (review, check, validate, approve, merge, …)}

**Design notes:** {required on BOTH the Simple and Complex Tracks for any deliverable that touches an existing skill — names the target skill's design model — `script-deterministic`, `LLM-driven`, or `hybrid` — and a one-sentence rationale showing the proposed implementation extends, not contradicts, that model. The track does NOT gate emission: a Simple-Track deliverable touching an existing skill MUST emit this block just as a Complex-Track one does, so the deliverable self-satisfies the §2.17 Architecture-Mismatch validator on the first validation pass. See Step 9c (Read Target Skill Design Intent), which applies to Simple Track Step 7 as well as Complex Track, and [`standards/outline-workflow-detail.md`](standards/outline-workflow-detail.md#step-9c-read-target-skill-design-intent) for the procedure. Omit only when the deliverable does not touch an existing skill (e.g., docs-only with no skill target, brand-new skill).}

**Profiles:** <!-- bucket: {production_only|test_only|documentation_only|mixed_code|mixed_with_docs|unknown} -->
- implementation
- {module_testing - only if the resolved bucket is production_only, test_only, mixed_code, or mixed_with_docs; never for documentation_only; unknown BLOCKS the deliverable}

**Affected files:**
- `{explicit/path/to/new-file}` (write-new)
- `{explicit/path/to/existing-file}` (write-replace)

**Change per file:** {what changes}

**Verification:**
- Command: `{resolved command}`
- Criteria: {criteria}

**Success Criteria:**
- {criterion 1}

**Intent gloss:** is copied verbatim by phase-4-plan into every derived task.description, so the sentence must stand alone without relying on the surrounding deliverable context.

The  comment on the **Profiles:** line is REQUIRED and records the resolved file-type bucket from the File-type classifier. The bucket determines which profiles are valid for the deliverable:

documentation_only → implementation only; never paired with module_testing. Verification cites pm-plugin-development:plugin-doctor:doctor-marketplace scan --paths {skill-dir}.
production_only → implementation + module_testing. Verification cites the resolved quality-gate and module-tests commands.
test_only → module_testing only (test-only deliverable). Verification cites the resolved module-tests command.
mixed_code → implementation + module_testing (production + test paths, no documentation). Verification cites the resolved quality-gate and module-tests commands.
mixed_with_docs → implementation + module_testing, with module_testing scope narrowed to the production/test paths only (declare the narrowed scope in a **Module_testing scope:** block above **Affected files:**).
unknown → BLOCKS the deliverable. Phase-4-plan emits a Q-Gate finding requiring the user to add a domain-extension claim for the unclaimed path(s) or correct the affected-files list. Never silently route to documentation_only.

Per-file intent marker (REQUIRED)

Every **Affected files:** entry MUST carry a trailing (intent) marker — a backticked path, one space, then the intent in parentheses: - `path/to/file.ext` (write-new). The marker is required and enum-validated by manage-solution-outline validate; an entry without a valid marker fails outline validation.

Classify each affected file's intent from its **Change per file:** description:

`Change per file` description	Intent
File is consulted/read but NOT modified by this deliverable	`read`
File is created fresh (does not exist yet)	`write-new`
File is modified in place (already exists)	`write-replace`
File is removed by this deliverable	`delete`

The intent authoritatively drives the downstream files_exist Q-Gate: read/delete require the file to exist pre-execution, write-new requires it to be ABSENT (the gate flags a declared-new file that already exists), and write-replace skips the existence check. Classify honestly — a write-new marker on a file that already exists, or a read marker on a file that does not, surfaces as a Q-Gate finding at plan time.

Write Solution Document (Simple Track only)

For Simple Track, write solution_outline.md. Use write on first entry, update on re-entry (Q-Gate loop):

python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline exists \
  --plan-id {plan_id}

If exists: false (first entry):

# 1. Get target path
python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline \
  resolve-path --plan-id {plan_id}

# 2. Write content directly via Write tool
Write({resolved_path}) with solution outline content including title, plan_id,
compatibility header, Summary, Overview, and Deliverables from Step 6

# 3. Validate
python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline \
  write --plan-id {plan_id}

If exists: true (Q-Gate re-entry):

# 1. Update content via Write tool to the same path
# 2. Validate
python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline \
  update --plan-id {plan_id}

Note: Complex Track - skill already wrote solution_outline.md in Step 10.

Log Completion

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  work --plan-id {plan_id} --level INFO --message "[ARTIFACT] (plan-marshall:phase-3-outline) Created solution_outline.md"

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  decision --plan-id {plan_id} --level INFO --message "(plan-marshall:phase-3-outline) Complete: {N} deliverables, Q-Gate: {pass/fail}"

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  work --plan-id {plan_id} --level INFO --message "[STATUS] (plan-marshall:phase-3-outline) Outline phase complete - {N} deliverables, Q-Gate: {pass/fail}"

Add visual separator after END log:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  separator --plan-id {plan_id} --type work

Transition Phase

python3 .plan/execute-script.py plan-marshall:manage-status:manage-status transition \
  --plan-id {plan_id} \
  --completed 3-outline

Return Results

Return minimal status - all data is in sinks:

status: success
plan_id: {plan_id}
track: {simple|complex}
deliverable_count: {N}
qgate_passed: {true|false}
qgate_pending_count: {0 if no findings}
qgate_validation_required: {true|false}

qgate_validation_required is true when the phase decided q-gate-validation must run (surgical-bypass predicate did NOT fire), and false otherwise (bypass fired or recipe path short-circuited at Step 3). The orchestrator (plan-marshall:plan-marshall/workflow/planning-outline.md) reads this flag after the phase returns and dispatches q-gate-validation as a sibling top-level Task when it is true.

Output

The "Return Results" block above (under Step 12) is the single source of truth for the return TOON. The minimum contract every workflow doc that implements ext-point-execution-context-workflow MUST return is:

status: success | error
display_detail: "<track {track}, {deliverable_count} deliverables, {qgate_pending_count} pending>"
qgate_validation_required: {true|false}

display_detail shape on success: "track {track}, {deliverable_count} deliverables, {qgate_pending_count} pending" (e.g. "track complex, 5 deliverables, 0 pending"); ≤80 chars, ASCII, no trailing period. On error, carries the short error label from § Error Handling.

All other fields (plan_id, track, deliverable_count, qgate_passed, qgate_pending_count, qgate_validation_required) are documented in "Return Results" above.

Error Handling

Scenario	Action
Track not set	Return `{status: error, message: "phase-2-refine incomplete - track not set"}`
Target not found (Simple)	Return error with invalid target
Change type not detected	Return `{status: error, message: "detect-change-type workflow failed to determine change type"}`
Skill workflow fails (Complex)	Return error, do not fall back
Q-Gate fails	Return with `qgate_passed: false` and findings
Request not found	Return `{status: error, message: "Request not found"}`

CRITICAL: If Complex Track skill workflow fails, do NOT fall back to grep/search. Fail clearly.

Phase-boundary metric bookkeeping

This skill does not invoke manage-metrics itself. The orchestrator (plan-marshall:plan-marshall workflows) records the 3-outline → 4-plan boundary via the fused manage-metrics phase-boundary call — see marketplace/bundles/plan-marshall/skills/manage-metrics/SKILL.md § phase-boundary for the API.

name	phase-3-outline
description	Two-track solution outline creation - Simple Track for localized changes, Complex Track for codebase-wide discovery

Phase Outline Skill

Role: Two-track workflow skill for creating solution outlines. Routes based on track selection from phase-2-refine.

Prerequisite: Request must be refined (phase-2-refine completed) with track field set.

Foundational Practices

Skill: plan-marshall:dev-agent-behavior-rules

Enforcement

Shared lifecycle patterns: See phase-lifecycle.md for entry protocol, completion protocol, and error handling convention.

Execution mode: Follow workflow steps sequentially. Each step that invokes a script has an explicit bash code block.

Prohibited actions:

Never access .plan/ files directly — all access must go through python3 .plan/execute-script.py manage-* scripts
Never skip the phase transition — use manage-status transition
Never improvise script subcommands — use only those documented below
Never fall back to simple track if complex track fails — return error
Never mutate source files outside .plan/local/plans/{plan_id}/ during outline. The outline phase is strictly analytical: it discovers, classifies, and writes solution documents into the plan workspace. Edits to any path under marketplace/, target/, .claude/, test/, doc/, or any other repository directory are categorically forbidden — those mutations are the responsibility of phase-5-execute. If a recipe or domain workflow proposes a fix, capture it as a deliverable in solution_outline.md rather than applying it directly.
Never invoke any *-doctor tool (e.g., plugin-doctor, plan-doctor) carrying fix, apply, --apply, or --fix during outline. Doctor tools may only be invoked in their read-only modes (verify, check, no flags) to surface findings. The apply/fix/--fix/--apply surfaces mutate source files and bypass the per-plan workspace boundary above — they are reserved for phase-5-execute task bodies that the planner explicitly authorized via a deliverable. This applies equally to Bash, Skill:, and SlashCommand: invocation shapes.

Constraints:

Strictly comply with all rules from dev-agent-behavior-rules, especially tool usage and workflow step discipline

Dispatched workflows vs inline steps

Loop-invariant inputs (cached at phase entry)

The clarified request narrative (read via manage-plan-documents read --plan-id {plan_id} --document request).
domains and compatibility (read via manage-files read --plan-id {plan_id} --file references.json).
module_mapping.toon if present at .plan/local/plans/{plan_id}/module_mapping.toon.
The architecture topology (read via manage-architecture topology at phase entry).
The resolved domain outline skill notation (resolved once via Step 9 domain-resolution).

Prohibited actions:

Never re-read loop-invariant inputs inside the per-deliverable loop body — re-reading inside the loop is envelope-cost waste; resolve all invariant inputs before the loop begins.

See extension-api/standards/dispatch-granularity.md § 5.1 (Heuristic 2 — bundle when steps share context) for the granularity rationale.

cwd for `.plan/execute-script.py` calls

manage-* scripts resolve .plan/ via the uniform cwd walk-up (ADR-002) — the nearest ancestor of cwd containing .plan/local. Phase-3-outline runs on the main checkout, so they resolve to main's .plan/; do NOT pin cwd, do NOT pass routing flags, and never use env -C. Build / CI / Sonar scripts accept --plan-id {plan_id} (preferred — auto-resolves the worktree via manage-status get-worktree-path) or --project-dir {worktree_path} (explicit override / escape hatch); the two flags are mutually exclusive. See plan-marshall:tools-script-executor/standards/cwd-policy.md.

Exit-code convention for `manage-*` script calls

Every manage-* script call documented below carries the following exit-code contract unless a step explicitly states otherwise:

exit_code == 0: parse the returned TOON and use the value as the step describes. exit 0 does NOT imply the operation succeeded — the manage-* scripts follow the canonical output contract (pm-plugin-development:plugin-script-architecture/standards/output-contract.md), under which an operation failure (file_not_found, field_not_found, plan_not_found, validation rejection, already-exists, etc.) exits 0 and carries the verdict in the stdout TOON status: error payload. Branch on the TOON status / value field to detect operation failures; never infer "the field was present" or "the plan exists" from a zero exit code.
exit_code != 0: STOP the phase and return an error TOON to the orchestrator carrying the script's stderr verbatim. A non-zero exit is reserved for a genuine script crash (exit 1 — uncaught exception, corrupt/non-dict payload, missing required file) or an argparse_rejection (exit 2 — silent swallowing of wrong_parameters rejections is the prohibited anti-pattern). The phase MUST NOT proceed on a non-zero exit; "log and continue" is equally forbidden.

`plan_id`	string	Yes	Plan identifier

Phase-Entry Worktree Assertion

Workflow Overview

Step 2: Load Inputs → Step 3: Recipe Detection → Step 4: Detect Change Type → Step 5: Route by Track → {Simple: Steps 6-8 | Complex: Steps 9-11} → Step 12: Return

Step 1: Check for Unresolved Q-Gate Findings

Purpose: On re-entry (after Q-Gate or user review flagged issues), address unresolved findings before re-running the outline.

For detailed procedures (query commands, finding-type handling, resolution logging), see standards/outline-workflow-detail.md.

Step 2: Load Inputs

Purpose: Load track, request, compatibility, and context from phase-2-refine output and sinks.

Receive Track from Phase-2-Refine Output

The track value (simple | complex) is received from the phase-2-refine return output, not read from references.json.

If track not provided in input, extract from decision.log:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  read --plan-id {plan_id} --type decision | grep "(plan-marshall:phase-2-refine) Track:"

Parse the output to extract track value from: (plan-marshall:phase-2-refine) Track: {track} - {reasoning}

Read Request

Read request (clarified_request falls back to original_input automatically):

python3 .plan/execute-script.py plan-marshall:manage-plan-documents:manage-plan-documents request read \
  --plan-id {plan_id} \
  --section clarified_request

Read Module Mapping (optional)

Check existence first (file is created by phase-2-refine and may not exist):

python3 .plan/execute-script.py plan-marshall:manage-files:manage-files exists \
  --plan-id {plan_id} \
  --file work/module_mapping.toon

If exists: true, read it:

python3 .plan/execute-script.py plan-marshall:manage-files:manage-files read \
  --plan-id {plan_id} \
  --file work/module_mapping.toon

If exists: false, continue without module mapping — downstream steps will use discovery or request context instead.

Read Domains

python3 .plan/execute-script.py plan-marshall:manage-references:manage-references get \
  --plan-id {plan_id} --field domains

Receive Compatibility from Phase-2-Refine Output

The compatibility and compatibility_description values are received from the phase-2-refine return output.

If compatibility not provided in input, read from marshal.json:

python3 .plan/execute-script.py plan-marshall:manage-config:manage-config \
  plan phase-2-refine get --field compatibility --audit-plan-id {plan_id}

Store as compatibility and derive compatibility_description from the value:

breaking → "Clean-slate approach, no deprecation nor transitionary comments"
deprecation → "Add deprecation markers to old code, provide migration path"
smart_and_ask → "Assess impact and ask user when backward compatibility is uncertain"

Receive Simplicity from Phase-2-Refine Output

The simplicity and simplicity_description values are received from the phase-2-refine return output.

If simplicity not provided in input, read from marshal.json (default lean when unconfigured):

python3 .plan/execute-script.py plan-marshall:manage-config:manage-config \
  plan phase-2-refine get --field simplicity --audit-plan-id {plan_id}

Store as simplicity and derive simplicity_description from the value:

lean → "Implement the strict minimum; remove or inline surplus structure"
pragmatic → "Prefer minimal, but keep low-risk structure that aids readability"
defensive → "Retain belt-and-suspenders structure (guards, abstraction seams) where uncertain"

Log Context (to work.log - status, not decision)

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  work --plan-id {plan_id} --level INFO --message "[STATUS] (plan-marshall:phase-3-outline) Starting outline: track={track}, domains={domains}, compatibility={compatibility}"

Step 3: Recipe Detection

Purpose: Recipe-sourced plans skip change-type detection and use the recipe skill directly for discovery, analysis, and deliverable creation.

If plan_source != recipe or field not found: continue with normal Step 4.

For detailed procedures (metadata reads, recipe resolution, skill loading), see standards/outline-workflow-detail.md.

Step 4: Detect Change Type

Purpose: Determine the change type for agent routing.

Run the deterministic classifier first; only dispatch the LLM workflow on the ambiguous branch.

Step 4a — Heuristic classifier (deterministic, no envelope):

python3 .plan/execute-script.py plan-marshall:manage-status:manage-status \
  change-type-heuristic --plan-id {plan_id} --persist

returns one of feature / bug_fix / tech_debt / enhancement / verification / analysis with ambiguous=false (and persists to status.metadata.change_type with --persist), OR
returns ambiguous=true when no keyword fires, the top two scores tie, or confidence falls below 0.7.

Step 4b — LLM fallback (only when ambiguous=true):

For detailed procedures (agent spawning, metadata read, post-check override logic), see standards/outline-workflow-detail.md.

Step 5: Route by Track

Based on track from Step 2:

If track == simple → go to Step 6. If track == complex → go to Step 9.

Simple Track (Steps 6-8)

For localized changes where targets are already known from module_mapping.

Step	Purpose	Key Action
6. Validate Targets	Verify target files/modules exist	`ls -la {target_path}` for each target
7. Create Deliverables	Map module_mapping to deliverables	MUST classify each deliverable's `affected_files` against the File-type classifier (six buckets: `production_only` / `test_only` / `documentation_only` / `mixed_code` / `mixed_with_docs` / `unknown`) BEFORE assigning `profiles[]`. For any deliverable that touches an existing skill, MUST also run the Step 9c design-intent classification and emit the resulting `Design notes:` block — this is track-agnostic and applies on the Simple Track too, so the deliverable self-satisfies §2.17 (Architecture-Mismatch) on the first validation pass. Use deliverable template, resolve verification commands via `architecture resolve`. The resolved bucket MUST be recorded as a comment in the `Profiles:` block (see Deliverable Template below).
8. Simple Q-Gate	Lightweight verification (with surgical bypass)	Bypass when surgical+bug_fix/tech_debt/verification+1 deliverable; otherwise check target existence + request alignment

File-type classifier (normative)

Value-change test-sweep rule (normative)

This rule is track-agnostic — it applies to deliverable authoring on both the Simple Track (Step 7) and the Complex Track (Step 10).

To enumerate the affected tests, sweep the test tree by identifier first, literal value only as a fallback:

Identifier-first search (primary) — search for the constant, enum-member, or default's name with a word-boundary anchor, not its value: Grep with \b{identifier}\b (or architecture find --pattern '*{identifier}*' for the structured inventory) across test/. Anchoring on the symbol name finds every test that references the changed member regardless of how it asserts the value, and the word boundary prevents substring false hits (e.g. MAX matching MAX_RETRIES).
Literal-value search (fallback only) — search for the old literal value solely when the identifier-first sweep yields nothing (e.g. the value is asserted inline with no named reference). When falling back to a literal, anchor on a word boundary and never sweep bare common literals (False, True, 0, 1, None, "") on their own — they produce overwhelming false positives. Pair the literal with the surrounding assertion or key context (e.g. {field_name}.*1) to keep the match precise.

Coverage contract: deliverable composition is where a per-deliverable scope × thoroughness cell would be declared — scope_estimate is the scope dial; thoroughness (coverage breadth + relation-tracing depth) is its orthogonal partner. The coupling constraint reject thoroughness ≥ T4 ∧ scope < component means a relation-tracing deliverable forces scope ≥ component. See the two-dial ladders, the grade-to-the-floor rule, and the coupling constraint in dev-agent-behavior-rules/standards/thoroughness.md.

Step 8 — Q-Gate surgical bypass rule (evaluated BEFORE dispatching the lightweight Q-Gate checks):

Bypass Q-Gate when ALL of the following are true:

scope_estimate == surgical, AND
change_type ∈ {bug_fix, tech_debt, verification}, AND
deliverable_count == 1 (exactly one deliverable was created in Step 7)

When bypass fires, log the decision and skip directly to Step 12:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  decision --plan-id {plan_id} --level INFO --message "(plan-marshall:phase-3-outline:qgate-bypass) Q-Gate skipped — scope_estimate=surgical, change_type={change_type}, 1 deliverable"

Otherwise, run the Simple Q-Gate checks documented in the detail standards. After Step 8, proceed to Step 12.

For detailed procedures (validation commands, deliverable template, verification resolution, Q-Gate checks, bypass rule examples), see standards/outline-workflow-detail.md.

Complex Track (Steps 9-11)

For codebase-wide changes requiring discovery and analysis.

Step	Purpose	Key Action
9. Resolve Domain Skill	Route to domain-specific or generic instructions	`resolve-outline-skill --domain {domain}`, then load `change-{change_type}.md`
9c. Read Target Skill Design Intent (track-agnostic — also runs from Simple Track Step 7)	For each deliverable that touches an existing skill, classify the skill's design model and record it on the deliverable	Read the target skill's `SKILL.md` and design-intent docs; classify as `script-deterministic`, `LLM-driven`, or `hybrid`; record the classification in the deliverable's `Design notes:` block; reroute or justify when the proposed implementation contradicts the model. This classification is NOT Complex-Track-only — the Simple Track runs the same procedure from Step 7 when a deliverable touches an existing skill, so the resulting `Design notes:` block lets the deliverable self-satisfy §2.17 on the first pass. Detailed procedure: `standards/outline-workflow-detail.md`.
10. Execute Workflow	Run discovery, analysis, write solution	Follow change-type instructions, resolve verification commands, write `solution_outline.md`. For each composed deliverable, MUST apply the File-type classifier to its `affected_files` BEFORE assigning `profiles[]` — the resolved bucket MUST be recorded as a comment in the `Profiles:` block (see Deliverable Template below). Step 10 includes a consumer-sweep when the deliverable deletes/renames a public symbol — see `consumer-sweep.md`.
10b. Self-Modifying Classification	Classify deliverables that touch plan-marshall runtime infrastructure and surface phasing decision	When predicate fires (path heuristic + `compatibility: breaking` + hard-cutover language), prompt author via `AskUserQuestion` for split / inline-rationale / additive-mode resolution. Standard: `ref-workflow-architecture/standards/self-modifying-classification.md`.
11. Q-Gate Verification	Signal q-gate-validation requirement (with surgical bypass)	Bypass when surgical+bug_fix/tech_debt/verification+1 deliverable → set `qgate_validation_required: false`; otherwise set `qgate_validation_required: true` in the return TOON so the orchestrator dispatches `plan-marshall:plan-marshall/workflow/q-gate-validation.md` as a sibling top-level Task after the phase returns (see `standards/outline-workflow-detail.md` for the activation contract). The orchestrator-dispatched workflow runs phase-3-applicable validators: existing checks 2.1-2.7, consumer-sweep §2.9, argparse-validator §2.10, tier-delta-validator §2.13, self-modifying-phased-rollout-validator §2.16, architecture-mismatch-validator §2.17.

Step 11 — Q-Gate surgical bypass rule (evaluated BEFORE signaling the Q-Gate validation requirement):

Bypass Q-Gate when ALL of the following are true:

scope_estimate == surgical, AND
change_type ∈ {bug_fix, tech_debt, verification}, AND
deliverable_count == 1 (exactly one deliverable was created in Step 10)

When bypass fires, log the decision, set qgate_validation_required: false in the return TOON, and skip directly to Step 12:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  decision --plan-id {plan_id} --level INFO --message "(plan-marshall:phase-3-outline:qgate-bypass) Q-Gate skipped — scope_estimate=surgical, change_type={change_type}, 1 deliverable"

Special-deliverable-class recognition rules (track-agnostic, thin)

Cooperative-lock deliverable class — Trigger: the deliverable's narrative introduces or modifies a cooperative cross-process lock or shared-state coordination primitive (merge locks, worktree allocation, plan-id reservation, leader election, any "claim a shared resource" flow). Required authoring action: emit a **Concurrency-correctness note:** block on the deliverable that names the check-then-act / TOCTOU window and points to the chosen mitigation. The note MUST cross-reference the TOCTOU / check-then-act mitigation menu in dev-general-code-quality/standards/code-organization.md — do NOT duplicate the mitigation menu.
Value-change deliverable class — Trigger: the deliverable changes a default value, constant, or enum member that tests may assert against. Required authoring action: scope the old-value test assertions into the deliverable's **Affected files:** so the production change and its test-consumer updates form one atomic deliverable. The note MUST cross-reference the enumeration discipline in dev-general-module-testing/standards/testing-methodology.md — do NOT duplicate the enumeration procedure.
Clean-break vs migration-shim deliverable class — Trigger: the deliverable's narrative (Change per file: / Refactoring: / summary) removes an internal code path — a function, method, parameter, branch, or script notation that is NOT a published cross-bundle public surface. Required authoring action: apply the four-condition clean-break checklist — (1) are all callers of the removed path in-plan? (2) is there no external / cross-bundle consumer? (3) can the removal land atomically in a single PR? (4) are the old-path tests removed or rewritten in the same plan? — and choose the shape: prefer the clean-break shape (remove the path outright, no shim) when ALL four conditions hold; otherwise default to a deprecation shim with a documented removal window. Cross-reference the checklist body, per-condition rationale, and the clean-break-vs-shim decision table in standards/outline-workflow-detail.md — do NOT duplicate the checklist here or on the deliverable.
Survey-scope deliverable class — Trigger: the deliverable's description mentions survey, discover, classify, or case-by-case (a discovery-style deliverable whose exact mutation set is not fully known at authoring time). Required authoring action: declare two disjoint fields on the deliverable — **Files to survey:** (the candidate-pool / analysis scope) and **Files expected to mutate:** (the mutation-scope upper bound) — and note that the retrospective affected_files_recall check runs against the expected-to-mutate subset, NOT the survey scope. Cross-reference the field semantics, the worked example, and the survey_vs_mutation_scope_declared outline check in standards/outline-workflow-detail.md — do NOT restate the field semantics or the check here.

The matching trigger predicates and authoring actions are documented as track-agnostic siblings to the Step 9c / Step 10b procedures in standards/outline-workflow-detail.md.

Retrospective-lesson recognition rule (track-agnostic, thin)

CRITICAL: If Complex Track skill workflow fails, do NOT fall back to grep/search. Fail clearly.

Domain-specific ext-outline-workflow skills MUST emit **Intent gloss:** per the deliverable template when a deliverable title contains a compound word whose head morpheme is a planning-domain verb (review, check, validate, approve, merge, …). The gloss is a single sentence (≤15 words) that restates the deliverable's goal using the tail morpheme's meaning, and phase-4-plan copies it verbatim into every derived task.description.

For detailed procedures (skill resolution, change-type loading, solution writing, Q-Gate agent interaction), see standards/outline-workflow-detail.md.

Step 12: Write Solution and Return

Deliverable Template (inline reference)

Each deliverable in solution_outline.md MUST follow this field order. The authoritative schema is in manage-solution-outline/templates/deliverable-template.md:

### {N}. {Deliverable Title}

**Metadata:**
- change_type: {feature|enhancement|tech_debt|bug_fix|analysis|verification}
- execution_mode: {automated|manual|mixed}
- domain: {domain}
- module: {module}
- depends: {none|N|N,M}

**Intent gloss:** {one-sentence disambiguation, max ~15 words — required when title head morpheme is a planning-domain verb (review, check, validate, approve, merge, …)}

**Design notes:** {required on BOTH the Simple and Complex Tracks for any deliverable that touches an existing skill — names the target skill's design model — `script-deterministic`, `LLM-driven`, or `hybrid` — and a one-sentence rationale showing the proposed implementation extends, not contradicts, that model. The track does NOT gate emission: a Simple-Track deliverable touching an existing skill MUST emit this block just as a Complex-Track one does, so the deliverable self-satisfies the §2.17 Architecture-Mismatch validator on the first validation pass. See Step 9c (Read Target Skill Design Intent), which applies to Simple Track Step 7 as well as Complex Track, and [`standards/outline-workflow-detail.md`](standards/outline-workflow-detail.md#step-9c-read-target-skill-design-intent) for the procedure. Omit only when the deliverable does not touch an existing skill (e.g., docs-only with no skill target, brand-new skill).}

**Profiles:** <!-- bucket: {production_only|test_only|documentation_only|mixed_code|mixed_with_docs|unknown} -->
- implementation
- {module_testing - only if the resolved bucket is production_only, test_only, mixed_code, or mixed_with_docs; never for documentation_only; unknown BLOCKS the deliverable}

**Affected files:**
- `{explicit/path/to/new-file}` (write-new)
- `{explicit/path/to/existing-file}` (write-replace)

**Change per file:** {what changes}

**Verification:**
- Command: `{resolved command}`
- Criteria: {criteria}

**Success Criteria:**
- {criterion 1}

**Intent gloss:** is copied verbatim by phase-4-plan into every derived task.description, so the sentence must stand alone without relying on the surrounding deliverable context.

documentation_only → implementation only; never paired with module_testing. Verification cites pm-plugin-development:plugin-doctor:doctor-marketplace scan --paths {skill-dir}.
production_only → implementation + module_testing. Verification cites the resolved quality-gate and module-tests commands.
test_only → module_testing only (test-only deliverable). Verification cites the resolved module-tests command.
mixed_code → implementation + module_testing (production + test paths, no documentation). Verification cites the resolved quality-gate and module-tests commands.
mixed_with_docs → implementation + module_testing, with module_testing scope narrowed to the production/test paths only (declare the narrowed scope in a **Module_testing scope:** block above **Affected files:**).
unknown → BLOCKS the deliverable. Phase-4-plan emits a Q-Gate finding requiring the user to add a domain-extension claim for the unclaimed path(s) or correct the affected-files list. Never silently route to documentation_only.

Per-file intent marker (REQUIRED)

Classify each affected file's intent from its **Change per file:** description:

`Change per file` description	Intent
File is consulted/read but NOT modified by this deliverable	`read`
File is created fresh (does not exist yet)	`write-new`
File is modified in place (already exists)	`write-replace`
File is removed by this deliverable	`delete`

Write Solution Document (Simple Track only)

For Simple Track, write solution_outline.md. Use write on first entry, update on re-entry (Q-Gate loop):

python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline exists \
  --plan-id {plan_id}

If exists: false (first entry):

# 1. Get target path
python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline \
  resolve-path --plan-id {plan_id}

# 2. Write content directly via Write tool
Write({resolved_path}) with solution outline content including title, plan_id,
compatibility header, Summary, Overview, and Deliverables from Step 6

# 3. Validate
python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline \
  write --plan-id {plan_id}

If exists: true (Q-Gate re-entry):

# 1. Update content via Write tool to the same path
# 2. Validate
python3 .plan/execute-script.py plan-marshall:manage-solution-outline:manage-solution-outline \
  update --plan-id {plan_id}

Note: Complex Track - skill already wrote solution_outline.md in Step 10.

Log Completion

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  work --plan-id {plan_id} --level INFO --message "[ARTIFACT] (plan-marshall:phase-3-outline) Created solution_outline.md"

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  decision --plan-id {plan_id} --level INFO --message "(plan-marshall:phase-3-outline) Complete: {N} deliverables, Q-Gate: {pass/fail}"

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  work --plan-id {plan_id} --level INFO --message "[STATUS] (plan-marshall:phase-3-outline) Outline phase complete - {N} deliverables, Q-Gate: {pass/fail}"

Add visual separator after END log:

python3 .plan/execute-script.py plan-marshall:manage-logging:manage-logging \
  separator --plan-id {plan_id} --type work

Transition Phase

python3 .plan/execute-script.py plan-marshall:manage-status:manage-status transition \
  --plan-id {plan_id} \
  --completed 3-outline

Return Results

Return minimal status - all data is in sinks:

status: success
plan_id: {plan_id}
track: {simple|complex}
deliverable_count: {N}
qgate_passed: {true|false}
qgate_pending_count: {0 if no findings}
qgate_validation_required: {true|false}

Output

status: success | error
display_detail: "<track {track}, {deliverable_count} deliverables, {qgate_pending_count} pending>"
qgate_validation_required: {true|false}

All other fields (plan_id, track, deliverable_count, qgate_passed, qgate_pending_count, qgate_validation_required) are documented in "Return Results" above.

Error Handling

Scenario	Action
Track not set	Return `{status: error, message: "phase-2-refine incomplete - track not set"}`
Target not found (Simple)	Return error with invalid target
Change type not detected	Return `{status: error, message: "detect-change-type workflow failed to determine change type"}`
Skill workflow fails (Complex)	Return error, do not fall back
Q-Gate fails	Return with `qgate_passed: false` and findings
Request not found	Return `{status: error, message: "Request not found"}`

CRITICAL: If Complex Track skill workflow fails, do NOT fall back to grep/search. Fail clearly.

Signals to orchestrator (Complex Track):

qgate_validation_required: true|false in the return TOON. The orchestrator (plan-marshall:plan-marshall/workflow/planning-outline.md) dispatches plan-marshall:plan-marshall/workflow/q-gate-validation.md as a sibling top-level Task when the flag is true (Step 11 — Q-Gate verification).

Loads Skills (Recipe path):

{recipe_skill} (Step 3 - recipe skill with input parameters, built-in or custom)

Loads Skills (Complex Track):

Domain outline skill via resolve-outline-skill (Step 9a, e.g., pm-plugin-development:ext-outline-workflow)
Change-type instructions from standards/change-{change_type}.md (Step 9b, generic fallback)

change-types.md - Change type vocabulary and agent routing
solution-outline-standard.md - Deliverable structure
workflow-architecture - Workflow architecture overview
outline-workflow-detail.md - Detailed track procedures (Q-Gate re-entry, recipe detection, change-type detection, Simple/Complex track steps)
consumer-sweep.md - Outline-time procedure that enumerates cross-bundle consumers of deleted/renamed public symbols before deliverable finalization (mandatory when delete/rename language applies to a public symbol)
dispatch-granularity.md - Dispatch granularity heuristics (10K rule, script-over-dispatch, bundle-over-iterate) — orienting reference for why the Complex Track bundles Steps 9c + 10 + 10b into one phase-3-outline dispatch rather than dispatching per-deliverable
