description

THE ONLY ENTRY POINT FOR CC10X. Activate this skill for build, debug, review, and plan requests. Use when the user asks to implement, fix, review, plan, test, refactor, or continue code work. Trigger keywords: build, implement, create, write, add, review, audit, debug, fix, error, bug, broken, plan, design, architect, spec, brainstorm, test, refactor, optimize, update, change, research, cc10x, c10x. CRITICAL: Route and execute immediately. Do not stop at describing capabilities.

cc10x Router

Runtime contract only. The router runs trust-first orchestration: route intent, hydrate workflow state, write workflow artifacts, execute the task graph, validate agent output, and fail closed on ambiguity, skipped work, or missing persistence.

1. Intent Routing

A keyword hit only NOMINATES a row; the request's primary deliverable DECIDES the route (e.g. "triage incoming issues" contains issue but its deliverable is triage, so it routes TRIAGE, not DEBUG). When the primary-deliverable test genuinely holds for more than one row, the lower Priority number wins.

Priority	Signal	Keywords	Workflow	Chain
1	ERROR	error, bug, fix, broken, crash, fail, debug, troubleshoot, issue	DEBUG	bug-investigator -> code-reviewer -> integration-verifier
2	PLAN	plan, design, architect, roadmap, strategy, spec, brainstorm	PLAN	exploration -> planner -> bounded fresh review loop
3	REVIEW	review, audit, analyze, assess, "is this good"	REVIEW	code-reviewer
4	ORIENT	zoom out, explain, understand, "how does X work", unfamiliar, "map this", "walk me through", "where is", "what does this do"	ORIENT	advisory orientation (no agents)
5	TRIAGE	triage, "incoming issues", "look at #", "triage #"	TRIAGE	triage-agent → optional exploration → agent-ready brief
6	CODEBASE-HEALTH	"codebase health", "improve architecture", "deepening", "ball of mud", "shallow modules", "architecture audit"	CODEBASE-HEALTH	architecture-scanner → HTML report → human picks → exploration (grilling) → feeds PLAN
7	DEFAULT	Everything else	BUILD	component-builder → [code-reviewer ‖ failure-hunter] → integration-verifier

Rules:

• Planning runs through the CC10x PLAN workflow so it gains orchestration state, workflow artifacts, intent contracts, and the bounded fresh review. Native plan mode (EnterPlanMode) is not a substitute for that, but it is not forbidden: if the user invokes it, treat the plan it produces as an input the PLAN workflow ingests (record it as the plan_file and run the fresh-review gate over it) rather than discarding it. Default to the CC10x PLAN workflow for "plan", "design", "architect", "brainstorm" requests.
• ERROR always wins over BUILD, but route on the PRIMARY DELIVERABLE, not the first keyword hit: "add a dark-mode toggle and fix the button alignment" is a BUILD whose scope includes a small fix, not a DEBUG. Use DEBUG when diagnosing/repairing broken behavior IS the deliverable; use BUILD when the deliverable is new/changed functionality that happens to mention fixing something along the way.
• REVIEW is advisory only. Never let REVIEW create code-changing tasks.
• ORIENT is read-only and advisory. It precedes DEFAULT/BUILD: a "help me understand this code" request must never fall through to BUILD and spawn a write builder. ORIENT spawns NO write agents and creates NO phase graph. If the user follows an orientation with a change request, re-route the new request (BUILD/DEBUG/PLAN) from scratch.
• TRIAGE is advisory-only. It categorizes, verifies, and writes agent-ready briefs for incoming issues/PRs. It never writes code. A triaged issue routes to BUILD or DEBUG only on a fresh user request — TRIAGE never auto-routes into a code-writing workflow. Category and wontfix decisions are high-blast-radius: stop for human input (do not auto-decide). Primary-deliverable rule: TRIAGE applies only when triage/categorization/briefing IS the deliverable (the request contains triage or incoming issues or look at # / triage #). A request that mentions a bug/issue/feature but asks to implement/fix/change it is BUILD or DEBUG — the primary deliverable is the change, not the triage. Do not route to TRIAGE unless the user explicitly asks to triage.
• CODEBASE-HEALTH is advisory-only upkeep. It surfaces deepening candidates and grills the chosen one. It never writes code. A chosen candidate routes to PLAN only on a fresh user request. The scanner writes a single HTML report to the OS temp dir (not the repo). Primary-deliverable rule: CODEBASE-HEALTH applies only when discovery/advice IS the deliverable (the request contains codebase health, improve architecture, deepening, ball of mud, shallow modules, or architecture audit). A request that asks to refactor/fix/change specific code is BUILD — the primary deliverable is the change, not the audit.

ORIENT move (read-only)

Triggered when the user wants to understand existing code, not change it ("zoom out", "explain", "how does X work", "I'm unfamiliar with", "map this", "walk me through", "where is X", "what does this do"). The router answers inline — no TaskCreate, no NEW workflow artifact, no phase graph, no write agents. (Edge case: if an artifact was pre-created before routing resolved — §2a permits early creation with workflow_type: pending — set its workflow_type to ORIENT and phase_cursor to orient, record the close in status_history, and create no phase graph. That is the only reason ORIENT/orient appear in the artifact enums.)

Orientation procedure:

1. Map the relevant modules/files for the named subject (use localViewStructure / localFindFiles / localSearchCode to locate, read only the slices needed to explain).
2. Trace ONE layer up: callers and dependents of the focal symbols via LSP call-hierarchy (lspCallHierarchy) and references (lspFindReferences); run localSearchCode first to get the exact lineHint before any LSP call.
3. Explain in the project's OWN vocabulary (names, terms, domain glossary from the code), not generic CS abstractions.
4. Stop at understanding. Do not propose or apply edits. If a change is clearly implied, end by offering to route it (BUILD/DEBUG/PLAN) — do not start it.

Distinguish from REVIEW: REVIEW judges quality ("is this good", audit); ORIENT only explains structure and flow. When both could match, prefer ORIENT for "help me understand", REVIEW for "tell me what's wrong".

2. Memory Load And Template Validation

Always run this before routing or resuming:

1. Bash("mkdir -p .cc10x")
2. Read(".cc10x/activeContext.md")
3. Read(".cc10x/patterns.md")
4. Read(".cc10x/progress.md")

Do not parallelize step 1 with reads — the reads assume the directory exists.

If a memory file is missing:

• Create it using the cc10x:memory-and-handoff template.
• Read it before continuing.

Required sections:

File	Required Sections
activeContext.md	## Current Focus, ## Recent Changes, ## Next Steps, ## Decisions, ## Learnings, ## References, ## Blockers, ## Session Settings, ## Last Updated
progress.md	## Current Workflow, ## Tasks, ## Completed, ## Verification, ## Last Updated
patterns.md	## User Standards, ## Common Gotchas, ## Project SKILL_HINTS, ## Last Updated

Auto-heal rule:

• Insert missing sections before ## Last Updated.
• After every Edit(...), immediately Read(...) and verify the new section exists.

JUST_GO:

• Read activeContext.md ## Session Settings.
• If AUTO_PROCEED: true, set JUST_GO=true.
• While JUST_GO=true, auto-default AskUserQuestion gates to the recommended option EXCEPT: REVERT, failure-stop gates, destructive finishing options (auto-pick Keep as-is; never merge/push/discard), and plans with unresolved Open Decisions (BUILD may not start). Log each auto-choice in ## Decisions.

Trust rule:

• JUST_GO never overrides explicit user/project standards, open plan decisions, or failure-stop gates.
• If a plan still has unresolved Open Decisions, BUILD may not start, even in JUST_GO.

2a. Workflow Artifact And Hook Policy

Core law:

• Durable router state lives under .cc10x/workflows/{workflow_uuid}.json
• Companion event log lives under .cc10x/workflows/{workflow_uuid}.events.jsonl
• Router-owned gates still include plan_trust_gate, phase_exit_gate, failure_stop_gate, memory_sync_gate, and skill_precedence_gate

Mandatory reference read:

• Before workflow creation, artifact mutation, hook policy changes, or resume logic that depends on artifact fields, immediately read references/workflow-artifact-and-hook-policy.md.
• That reference contains the verbatim artifact schema, event log contract, hook policy, and gate wording extracted from the prior router monolith. Treat it as load-bearing orchestration law, not optional background.

3. Task Metadata Contract

Every CC10X task description starts with normalized metadata lines:

wf:{workflow_uuid}
kind:{workflow|agent|remfix|memory|reverify|research}
origin:{router|component-builder|bug-investigator|code-reviewer|integration-verifier|planner}
phase:{build|build-implement|build-review|build-hunt|build-verify|build-doc-sync|build-finish|debug|debug-investigate|debug-review|debug-verify|review|review-audit|plan|plan-create|plan-review-gap-1|plan-review-gap-2|triage|codebase-health|memory-finalize|re-review|re-hunt|re-verify|re-plan|research-web|research-github}
plan:{path|N/A}
scope:{ALL_ISSUES|CRITICAL_ONLY|N/A}
reason:{short reason or N/A}

Rules:

• ALL SEVEN metadata lines (wf:, kind:, origin:, phase:, plan:, scope:, reason:) are present on EVERY CC10X task — use N/A where a field does not apply. The TaskCompleted hook audits exactly this invariant; the task-graph templates already satisfy it.
• wf: always carries the generated workflow_uuid (wf-<ts>-<hex>), never a Claude TaskCreate task id. This aligns with the hard rule "never treat stored task IDs as durable truth across workflows."
• Router must generate workflow_uuid before TaskCreate() and use it from the first write.
• kind: drives resume, routing, and counting logic.
• origin: on a kind:remfix task names the agent whose findings triggered the fix (never N/A there).
• plan: carries the real plan path on workflow, agent, reverify, and memory tasks when a plan exists.
• reason: carries a meaningful short reason (not N/A) on remediation and research tasks.
• The router must never depend on loose prose when metadata can answer the question.

4. Resume And Hydration

After memory load:

TaskList()

Hydration rules:

• Find active parent workflow tasks by subject prefix CC10X BUILD:, CC10X DEBUG:, CC10X REVIEW:, CC10X PLAN:.
• If more than one active workflow exists, scope by the current conversation and matching wf: markers. Do not resume a workflow you cannot scope confidently.
• Reconstruct runnable tasks from TaskList() and TaskGet() using wf: + kind: + phase:. Do not rely on stored task IDs for correctness.
• Read and write only the .cc10x/ state namespace (memory .cc10x/*.md, workflows .cc10x/workflows/*). Ignore any legacy version-segmented layout such as .cc10x/v10/* or .claude/cc10x/* left over from older installs during hydration.
• [cc10x-internal] memory_task_id in activeContext.md is only a transient optimization. If it is missing, stale, or points to a different wf:, ignore it and reconstruct the memory task from the current workflow scope. [EASY TO MISS: stale memory_task_id is the #1 cause of cross-workflow pollution]
• Never use an unscoped fallback like "first pending Memory Update task". [EASY TO MISS: unscoped lookups silently pick up orphan tasks from prior workflows]

Resume algorithm:

0. If .cc10x/stop-state.json or .cc10x/precompact-state.json exists (written by the Stop/PreCompact hooks), read it as a HINT for which wf: and phase_cursor were live when the session last ended. It is a hint only — task metadata and the workflow artifact stay authoritative; discard the hint on any mismatch.
1. Identify the active parent workflow.
2. Extract workflow_uuid from the wf: line.
3. Read all CC10X tasks whose descriptions contain that wf:.
4. Derive runnable tasks from status and blockedBy.
5. Reconstruct the memory task as the unique pending/in_progress kind:memory task in the same wf:.

Scope-decision resume:

• Before normal routing, check activeContext.md ## Decisions for a live marker:
  • [SCOPE-DECISION-PENDING: wf:{workflow_uuid} reason:{...}]
• If present, treat the current user reply as the answer to that pending BUILD scope gate:
  • critical only -> create the pending REM-FIX with scope:CRITICAL_ONLY
  • all issues -> create the pending REM-FIX with scope:ALL_ISSUES
  • anything else -> ask again with the same two options and stop
• After consuming a valid answer:
  • remove the pending marker from ## Decisions
  • create the scoped REM-FIX
  • block downstream re-review / verifier tasks as normal
  • stop after task creation so the next turn resumes from task state, not from repeated prose parsing
  • [EASY TO MISS: When persisting user decisions, use the user's exact words. Paraphrasing introduces drift that compounds across resume cycles.]

Safety rules:

• If a task list is shared across sessions, always scope by wf: before resuming.
• If a task has status=in_progress and unresolved blockers, treat it as waiting on remediation, not as a free-running orphan.
• If a task has status=in_progress and no blockers, ask the user whether to resume, delete, or mark complete.
• If legacy tasks exist with subjects starting BUILD:, DEBUG:, REVIEW:, or PLAN: without the CC10X prefix, ask whether to resume the legacy workflow or start a fresh CC10X workflow.

5. Workflow Preparation

Shared preparation

Before creating a new workflow:

• Read activeContext.md ## References to discover Plan, Design, and prior Research files.
• Read activeContext.md ## Decisions for prior planner/build clarifications.
• Read progress.md ## Current Workflow and ## Tasks for pending work that should resume instead of duplicating.
• Read the latest .cc10x/workflows/*.json artifact if one exists for the current conversation.

Intent Readiness Gate (MANDATORY before PLAN or BUILD): Before dispatching to planner or builder, verify the intent contract meets three conditions:

1. Context-bounded: The full intent (goal + constraints + acceptance criteria) fits within the agent's prompt scaffold without truncation. If the intent requires loading more than 5 source files to be understood, decompose first (switch to PLAN).
2. Contradiction-free: No acceptance criterion contradicts a stated constraint or non-goal. If contradictions exist, halt and persist pending_gate="intent_contradiction".
3. Sufficiently specific: Every acceptance criterion maps to at least one verifiable scenario. If a criterion is unverifiable ("make it better" without a metric), halt and ask for specificity.

Router-owned interface fields:

• plan_mode: direct | execution_plan | decision_rfc
• verification_rigor: standard | critical_path
• checkpoint_type: none | human_verify | decision | human_action
• proof_status: passed | gaps_found | human_needed

BUILD preparation

• Before any BUILD-specific readiness decision or child-task creation, immediately read references/build-workflow.md.
• Use the ### BUILD preparation and ### BUILD task graph blocks in that file as the canonical BUILD law.

DEBUG preparation

• Before any DEBUG-specific readiness decision or child-task creation, immediately read references/debug-workflow.md.
• Use the ### DEBUG preparation and ### DEBUG task graph blocks in that file as the canonical DEBUG law.

REVIEW preparation

• Before any REVIEW-specific readiness decision or child-task creation, immediately read references/review-workflow.md.
• Use the ### REVIEW preparation and ### REVIEW task graph blocks in that file as the canonical REVIEW law.

PLAN preparation

• Before any PLAN-specific readiness decision or child-task creation, immediately read references/plan-workflow.md.
• Use the ### PLAN preparation and ### PLAN task graph blocks in that file as the canonical PLAN law.
• If planner clarification, review-loop findings, or plan remediation rules trigger later in the workflow, also read references/remediation-and-research.md before continuing.

6. Workflow Task Graphs

Parent workflow creation

Use this pattern for every new workflow:

1. Generate a stable workflow UUID before TaskCreate():

workflow_uuid = "wf-" + UTC timestamp + "-" + 8 hex chars

1. Create the parent workflow task with that UUID from the first write:

TaskCreate({
  subject: "CC10X {WORKFLOW}: {summary}",
  description: "wf:{workflow_uuid}\nkind:workflow\norigin:router\nphase:{build|debug|review|plan}\nplan:{plan_file or 'N/A'}\nscope:N/A\nreason:User request\n\nUser request: {request}\nChain: {chain description}",
  activeForm: "{workflow active form}"
})

1. Immediately create the workflow artifact and event log. Do NOT hand-type the artifact JSON. Copy the canonical skeleton, then substitute only the live fields:

Bash(command="mkdir -p .cc10x/workflows && cp \"${CLAUDE_PLUGIN_ROOT}/skills/cc10x-router/references/workflow-artifact.skeleton.json\" .cc10x/workflows/{workflow_uuid}.json")

Then Edit the copied file, replacing each placeholder token with the live value (the skeleton ships every required key already populated with safe defaults — you only fill these):

• __WORKFLOW_UUID__ → {workflow_uuid} (appears twice: workflow_uuid and workflow_id)
• __WORKFLOW_TYPE__ → {WORKFLOW} (BUILD | DEBUG | REVIEW | PLAN | ORIENT | TRIAGE | CODEBASE-HEALTH) — if routing (§5) has not yet determined the workflow type, use pending and update it after §5 resolves. Never hardcode BUILD before routing completes. The artifact may be created before routing (to capture state early), but workflow_type must reflect the actual routed type after §5.
• __USER_REQUEST__ → the user request (JSON-escape quotes/newlines)
• __PHASE__ → {build|debug|review|plan|orient|triage|codebase-health}
• __ISO_TIMESTAMP__ → the current UTC ISO timestamp (appears 3×: status_history[0].ts, created_at, updated_at)

Use Edit(replace_all=true) for __WORKFLOW_UUID__ and __ISO_TIMESTAMP__ since each repeats. Then write the event log:

Write(
  file_path=".cc10x/workflows/{workflow_uuid}.events.jsonl",
  content="{\"ts\":\"{iso_timestamp}\",\"wf\":\"{workflow_uuid}\",\"event\":\"workflow_started\",\"phase\":\"{build|debug|review|plan}\",\"task_id\":\"{parent_task_id}\",\"agent\":\"router\",\"decision\":\"start\",\"reason\":\"User request\"}\n"
)

Read-back gate (MANDATORY before any child TaskCreate): Read(".cc10x/workflows/{workflow_uuid}.json") and confirm (a) it parses as JSON, (b) workflow_uuid equals the generated UUID, and (c) no __PLACEHOLDER__ tokens remain. If any check fails, fix the file and re-read before proceeding. The PostToolUse artifact guard also validates this write in block mode and will reject a malformed or key-missing artifact — but the router must not rely on the guard alone; confirm the read-back first.

Only create child tasks after the workflow artifact exists and the read-back passes.

BUILD task graph

• See references/build-workflow.md and apply its ### BUILD task graph block verbatim before creating BUILD child tasks.

DEBUG task graph

• See references/debug-workflow.md and apply its ### DEBUG task graph block verbatim before creating DEBUG child tasks.

REVIEW task graph

• See references/review-workflow.md and apply its ### REVIEW task graph block verbatim before creating REVIEW child tasks.

PLAN task graph

• See references/plan-workflow.md and apply its ### PLAN task graph block verbatim before creating PLAN child tasks.

Marker rules

• BUILD writes [BUILD-START: wf:{workflow_uuid}]
• DEBUG writes [DEBUG-RESET: wf:{workflow_uuid}]
• PLAN writes [PLAN-START: wf:{workflow_uuid}]

7. Dispatcher And Agent Prompt Contract

Explicit dispatcher

Task Phase / Kind	Agent
build-implement	cc10x:component-builder
debug-investigate	cc10x:bug-investigator
build-review, debug-review, review-audit, re-review	cc10x:code-reviewer
build-hunt, re-hunt	cc10x:failure-hunter
build-verify, debug-verify, re-verify	cc10x:integration-verifier
plan-create, re-plan	cc10x:planner
plan-review-gap-1, plan-review-gap-2	cc10x:plan-gap-reviewer
research-web	cc10x:researcher
research-github	cc10x:researcher
triage	cc10x:triage-agent
codebase-health	cc10x:architecture-scanner
kind:remfix + origin:bug-investigator	cc10x:bug-investigator
build-doc-sync	cc10x:doc-syncer
kind:remfix + origin:code-reviewer / origin:integration-verifier / origin:router	cc10x:component-builder

Per-role model-tier policy

Model selection comes from agent frontmatter; the router cannot set it per dispatch. Two live rules: (1) never edit a gating agent's (code-reviewer, integration-verifier, plan-gap-reviewer) frontmatter below mid-tier — the cheapest tier rubber-stamps; (2) never downgrade a gating role to save tokens, including under JUST_GO.

ADVISORY — for humans tuning frontmatter; the router cannot act on this table at dispatch time. Tiers are abstract: cheap (small/fast), standard (mid), capable (frontier).

Role / phase	Recommended tier	Why
component-builder on trivial scope, transcription/mechanical builds (rote wiring, single-change, codegen-from-spec)	cheap	Mechanical execution against an explicit spec; little judgment.
doc-syncer	cheap	Mechanical diff-driven doc edits.
component-builder on multi-file / cross-module integration	standard	Real wiring decisions across files; needs coherence.
code-reviewer	standard (FLOOR)	Judgment under adversarial intent; see reviewer floor below.
bug-investigator	standard	Hypothesis search; escalate to capable on a stubborn root cause.
planner, plan-gap-reviewer	capable	Architecture and decomposition; cheap planning poisons the whole chain.
integration-verifier (final phase, REVERT authority)	capable	Last line before "done"; must not miss scenario gaps.
researcher	standard	Retrieval + synthesis.

cc10x ships model: haiku on doc-syncer (safely mechanical) and model: inherit everywhere else so the user's session model choice is respected. Never claim a tier was applied when the mechanism cannot apply it. Turn-count dominates price — a capable model that one-shots a phase is cheaper than a cheap model that loops three times re-reading state and re-trying. When a role tends to iterate (planner, verifier, stubborn investigation), prefer the higher tier even though its per-token cost is greater: fewer turns wins.

Prompt scaffold for every agent

## Task Context
- Task ID: {task_id}
- Parent Workflow ID: {workflow_uuid}
- Task Phase: {phase}
- Plan File: {plan_file or 'None'}
- Workflow Scope: wf:{workflow_uuid}
- Workflow Artifact: .cc10x/workflows/{workflow_uuid}.json

## User Request
{request}

## Requirements
{clarified requirements or 'See plan/design files'}

## Memory Summary
{brief activeContext summary}

## Project Patterns
{User Standards + Common Gotchas, trimmed if needed}

## Domain Context
{If UBIQUITOUS_LANGUAGE.md, DOMAIN_GLOSSARY.md, docs/domain/*.md, or project-context.md exist, include content. Otherwise omit section.}

## SKILL_HINTS
{router-detected skill list or "None"}

Anti-anchoring exception: for adversarial read-only dispatches (code-reviewer, plan-gap-reviewer) OMIT ## Memory Summary — it carries the implementer's own narrative (decisions, learnings) and anchors the auditor. Keep ## Project Patterns (user standards and gotchas are neutral law, not author narrative). Approved decisions the reviewer genuinely needs travel via ## Pre-Answered Requirements / ## Intent Contract, never via the memory summary.

Optional sections:

• ## Pre-Answered Requirements for BUILD when router already gathered decisions.
• ## Intent Contract when a plan or design already defined goal, constraints, acceptance criteria, and named scenarios.
• ## Research Files only when at least one research file exists.
• ## Research Quality only when at least one research result exists.
• ## Design File only for planner.
• ## Planning Review Findings only for re-plan.
• ## Original User Request only for plan-gap-reviewer.
• ## Approved Context Files only for plan-gap-reviewer.
• ## Previous Agent Findings only for integration-verifier and only after a review phase ran.

Prompt assembly rule

• Every routed prompt must be self-contained from the workflow artifact, approved files, and the current task contract.
• Do not rely on prior chat turns or completed-phase narrative when the same fact already exists in the workflow artifact, plan, design, or research files.
• Include only the current-phase objective, live blockers, approved decisions, and directly relevant evidence. Omit unrelated completed-phase detail.
• Anti-pre-judging guard (adversarial dispatches only): before dispatching code-reviewer, failure-hunter, or plan-gap-reviewer, grep the drafted prompt against the SELF-CHECK BLOCKLIST in references/workflow-artifact-and-hook-policy.md §Dispatch-Prompt Construction Rules; any hit → rewrite it out before dispatch. A hit means you are pre-judging the reviewer's verdict before they have seen the code. The router knows the plan, the intent contract, and the approved decisions — that knowledge can unknowingly inject bias ("the plan chose approach X, so don't flag Y"). Reviewers must form their own opinion from the diff. State approved decisions as neutral facts ("approach X was approved for reason Z"), never as instructions to suppress findings.

Deterministic skill hints

• Router is the only authority allowed to load internal CC10X skills.

• Agents may not self-activate frontend or architecture.

• Include cc10x:frontend only when the request, changed files, plan, or design targets UI/frontend work. The skill has two modes: authoring (build UI with patterns) and critique (score built UI). Router selects mode via dispatch context.

• Include cc10x:architecture only for multi-component, API, schema, auth, or integration-heavy work.

• Include cc10x:research only when planner or investigator receives ## Research Files.

• Include cc10x:exploration only on an explicit de-risk/spike intent ("spike", "try out", "what should this look like", "prototype", "throwaway") — never as the default for a real build. The skill has two modes: design (brainstorm a design) and spike (throwaway prototype). Absorbing a spike's answer is a fresh gated BUILD, not promotion.

• Include cc10x:codebase-hygiene only when (a) the code-reviewer is asked for a reuse/consolidation audit or the request targets semantic duplication, OR (b) the request targets retrofitting/deepening shallow modules in EXISTING code (not greenfield architecture, which stays cc10x:architecture). The skill has two modes: duplicate detection and module deepening.

• Include cc10x:mcp-cli only when a researcher needs a one-off MCP capability that is not already mounted.

• Include cc10x:code-review only when a human/external reviewer's feedback (pasted PR comments, review notes, "can you change X") must be acted on — it governs verify-before-agreeing in the MAIN session, not the internal reviewer→router→fix loop.

• Include cc10x:memory-and-handoff only when work is being handed to a coworker, a different tool, or a fresh non-cc10x session.

• Include project/domain skills only from patterns.md ## Project SKILL_HINTS.

• Skill precedence is strict:

  1. explicit user prompt
  2. project CLAUDE.md / repo standards / user standards
  3. approved plan and design docs
  4. domain-specific external skills
  5. internal CC10X skills
  6. model heuristics

Previous Agent Findings handoff

When invoking integration-verifier, build and pass the ## Previous Agent Findings section per the Verifier findings handoff law in §13 — read results.reviewer and results.hunter from the workflow artifact and use the exact template defined there (single source). DEBUG skips the hunter.

Task metrics and timing telemetry

• Timing telemetry is measurement only. It must never bypass gates, phase exit, or remediation rules.
• After TaskGet() / TaskList(), if Claude Code exposes task duration metrics, persist them into:
  • telemetry.workflow_wall_clock_seconds
  • telemetry.agent_wall_clock_seconds.{agent}
• If task metrics are unavailable, keep task_metrics_available="unknown" and continue. Missing telemetry is never a reason to advance or block a workflow.
• When integration-verifier reports a ### Timing & Workload section, persist:
  • telemetry.verifier.phase_exit_proof_runs
  • telemetry.verifier.extended_audit_runs
  • telemetry.verifier.workload_seconds
• Use telemetry to explain latency. Do not use it to auto-reduce verification scope.

8. Post-Agent Validation

Read-only contracts

Primary signal:

• Line 1: CONTRACT {"s":"...","b":...,"cr":...}

Fallback heading on line 2:

• ## Review: Approve|Changes Requested
• ## Verification: PASS|FAIL
• ## Planning Review: Pass|Findings

Verdict extraction:

1. Try the envelope on line 1.
2. If envelope is missing or malformed, scan the first 5 lines for the heading.
3. Extract CRITICAL_ISSUES from ### Critical Issues.
4. If the line-1 envelope AND the first-5-lines fallback heading are both absent, or any required contract field is missing, run inline verification rather than approving.
5. Detect SELF_REMEDIATED from task state:
   • If the task remains in_progress and blockedBy is non-empty after the agent stops, treat it as self-remediated.
6. For integration-verifier, parse scenario accounting:
   • SCENARIOS_TOTAL
   • SCENARIOS_PASSED
   • SCENARIOS_FAILED
   • Fail validation if those counts do not reconcile with the evidence array.
   • Fail validation if any scenario omits explicit Expected or Actual evidence.

Read-only structured intent fields:

• REMEDIATION_NEEDED: true|false
• REMEDIATION_REASON: ...
• REMEDIATION_SCOPE_REQUESTED: N/A|CRITICAL_ONLY|ALL_ISSUES
• REVERT_RECOMMENDED: true|false
• PLANNING_REVIEW_STATUS: PASS|FINDINGS
• BLOCKING_FINDINGS_COUNT: [number]
• REPLAN_NEEDED: true|false
• REPLAN_REASON: ...

Compatibility rule:

• Accept legacy self-healed blocked task behavior during migration.
• Prefer the new structured remediation fields over task-state inference when both exist.

Write-agent YAML contracts

For write agents, parse the final fenced YAML block under ### Router Contract (MACHINE-READABLE).

Before post-agent validation, read references/workflow-artifact-and-hook-policy.md §contracts for the per-agent required-field table and the contract-override pass conditions.

If the YAML block is missing or malformed:

• Treat the task as invalid output.
• Do not continue the workflow based on prose alone.
• Re-run inline verification and fail safe.

Inline exploration handoff

After Skill(skill="cc10x:exploration"), parse the fenced YAML block under ### Brainstorming Handoff (MACHINE-READABLE).

Required field:

• DESIGN_FILE

If present:

• persist it into workflow artifact design_file
• pass it to planner as ## Design File
• do not require activeContext.md to be updated first

Contract overrides

• Before treating any agent STATUS/verdict as a pass, read references/workflow-artifact-and-hook-policy.md §contracts and apply the per-agent contract-override pass conditions verbatim (the STATUS=PASS/FIXED/APPROVE/PLAN_CREATED/COMPLETE gates, plus the reviewer rubber-stamp fallback).

Convergence rule:

• If evidence is incomplete, contradictory, or missing for a required pass path, do not advance the workflow.
• Set the workflow artifact quality.convergence_state to needs_iteration and stop on the appropriate remediation or clarification gate instead of treating the task as good enough.

9. Remediation And Workflow Rules

• When remediation, scope resolution, review-to-build escalation, planner clarification, investigation continuation, or the verifier REVERT gate is in play, immediately read references/remediation-and-research.md.
• Use the ## 9. Remediation And Workflow Rules block there as canonical router law.

10. Research (Trigger, Quality, Files)

• Research (trigger, quality, files): whenever research is triggered (including research task creation), consumed, summarized, or handed to planner/investigator, read references/remediation-and-research.md and apply its ## 10. Research Orchestration, ## Research Quality, and ## Research Files blocks.

11. Re-Review Loop

• See references/remediation-and-research.md and apply its ## 11. Re-Review Loop block whenever a kind:remfix task completes.

11b. Loop Discipline (Vocabulary)

The harness is a loop engine. These concepts govern how the loop runs:

Concept	Meaning
Trigger	The event that starts or resumes a loop iteration — user request, agent completion, checkpoint resolution. Every loop iteration has exactly one trigger.
Checkpoint	A point where the loop pauses for human input. Only on irreversible actions, real scope changes, or input only the user can provide. Checkpoints are NOT for narration or "want me to continue?" prompts.
Push right	Defer checkpoints as far as possible — do maximal work before involving the human. The loop should never stop on a promise or plan when it could act. If the next step is reversible and follows from the original request, proceed without asking.
Brief	The decision-ready summary the loop produces when pausing. Not raw output, not a diary — the one thing the human needs to decide next. Outcome first, supporting detail second.
Cycle	One complete plan → build → verify → learn iteration. The circuit breaker pauses the loop for a human checkpoint at the 3rd remediation cycle (single definition: references/remediation-and-research.md); cycles beyond 3 run only on explicit user go-ahead.
Convergence	The loop's quality signal — when quality.convergence_state transitions from needs_iteration to converged, the loop is complete. Never declare convergence on prose alone.

Autonomous mode: When the user sets a goal that spans multiple iterations (e.g., /goal or explicit "do this end-to-end"), the loop runs without checkpointing for reversible actions. The user is not watching in real time and cannot answer questions mid-task. Before ending a turn, check the last paragraph — if it is a plan, analysis, question, list of next steps, or a promise about work not yet done, do that work now with tool calls. End the turn only when the task is complete or blocked on input only the user can provide.

12. Chain Execution Loop

1. TaskList()
2. Select tasks in the active `wf:` where:
   - status is pending or in_progress
   - blockedBy is empty or all blockers are completed
3. If the runnable task kind is memory:
   - execute inline in the main context
   - persist workflow artifact results + Memory Notes from the task description
   - append `memory_finalized` to `.cc10x/workflows/{wf}.events.jsonl`
   - clean up the matching [cc10x-internal] memory_task_id entry
   - mark the memory task completed
   - mark the parent workflow task completed
   - continue
4. Otherwise, map each runnable task through the dispatcher table.
5. Mark each task in_progress before invoking its agent. If `code-reviewer` and `failure-hunter` are both ready in BUILD: mark both in_progress first, invoke them in the same message. They are read-only and safe to parallelize.
   - If parallel invocation fails or is unavailable (API error, rate limit, agent not found): fall back to sequential execution — dispatch `code-reviewer` first, wait for it to complete, then dispatch `failure-hunter`. Do NOT substitute the hunter with a different agent (e.g., bug-investigator). Do NOT skip the hunter. The hunter is a read-only agent with a specific adversarial posture — no other agent can replace it. Never block a workflow because parallelism is unavailable. Log `event=parallel_fallback` in the workflow event log.
6. After each agent returns:
   - capture memory payload immediately
   - validate output
   - persist task-state side effects
   - if BUILD review and hunt are both complete for the current phase, write one router-owned merged findings summary into the existing workflow results before verifier handoff
   - apply workflow rules
   - for BUILD, run `phase_exit_gate`; if the current phase is not complete, persist `phase_status={partial|blocked}` and stop
   - never advance to the next phase or workflow step on apology prose alone
   - if two agents in the same phase return contradictory verdicts (e.g., reviewer approves but verifier fails on the same evidence), treat the blocking verdict as authoritative (FAIL over PASS, CHANGES_REQUESTED over APPROVE); never average or reconcile the signals. Log the contradiction in `status_history`.
   - **Cross-reviewer agreement promotion:** if `code-reviewer` and `failure-hunter` independently flag the SAME finding (same file:line, same defect, raised from different passes), that is stronger signal than either alone — promote the merged finding's confidence by one tier (80→90, or mark it `cross-confirmed` in the merged findings summary). Agreement between two mutually-blind reviewers is independent confirmation; use it. Promotion never overrides the quote-the-line gate — a finding without a verbatim `file:line` quote cannot be promoted, only demoted.
   - doc-syncer `STATUS=SKIPPED` is a passing state; advance to Memory Update immediately
   - doc-syncer STATUS=PARTIAL: soft pass; advance to Memory Update; persist doc_sync_partial=true in workflow artifact results.doc_syncer for user review
7. Repeat until all tasks in the active `wf:` are completed.

After every agent completion

0. Capture memory payload FIRST — before the pre-check, validation, or any task-state mutation (compaction can fire between agent return and parse; an uncaptured payload is lost).

   • READ-ONLY agents: extract ### Memory Notes (For Workflow-Final Persistence) immediately after return.
   • WRITE agents: extract MEMORY_NOTES from YAML immediately after return.

1. Pre-check before processing agent output:

   • Did the agent address the assigned scope (not a subset or superset)?
   • Did tests, builds, or checks referenced in the contract actually run (not merely described)?
   • Is follow-up work needed that the agent did not self-remediate? If any answer is "no" or "unknown", treat as incomplete and apply the fallback validation path below.

2. TaskGet({ taskId }) or TaskList() to verify final task state.

3. WRITE agents:

   • They should already have called TaskUpdate(status="completed").
   • Parse YAML before continuing.

4. READ-ONLY agents:

   • Router owns completion fallback for read-only tasks.
   • If the task is still not completed after agent return, router applies fallback TaskUpdate(status="completed").
   • Blockers or findings may change workflow routing, but they never transfer orchestration ownership back to the read-only agent.

5. Memory payload was already captured in step 0:

   • READ-ONLY agents: append extracted notes to the memory task description.
   • WRITE agents: append deferred or supplemental payload needed by the memory task.

6. Update .cc10x/workflows/{workflow_uuid}.json with:

   • intent contract fields from planner output when available
   • task ids
   • phase status
   • phase cursor changes only after phase_exit_gate passes
   • structured agent results
   • scenario evidence grouped by agent
   • plan/design/research file paths
   • capabilities and chosen research backend path when applicable
   • research quality and round metadata when applicable
   • telemetry:
     • task metrics duration when available
     • loop counters
     • verifier workload classification when present
   • quality/convergence state

Verifier findings handoff

Before invoking integration-verifier in BUILD:

• Read results.reviewer and results.hunter from the workflow artifact.

• Build ## Previous Agent Findings exactly in the format verifier expects:

  ## Previous Agent Findings
  
  ### Code Reviewer
  **Verdict:** {Approve|Changes Requested}
  **Critical Issues:**
  {reviewer critical issues or "None"}
  
  ### Failure Hunter
  **Critical Issues:**
  {hunter critical issues or "None / not in this workflow"}
  

• Never invoke verifier without that section when review/hunt already ran.

Post-verifier finding validation (act on hallucinated findings): after the verifier returns, read its ### Reviewer Finding Validation section. For any finding the verifier marked validated: false, DROP that finding from the merged findings set before creating a REM-FIX task — a hallucinated critical finding must not gate the phase or waste a builder cycle. Log the dropped finding in status_history (finding_dropped: hallucinated — verifier could not confirm quote at file:line). For validated: degraded CRITICAL/HIGH findings, KEEP them in the blocking set (fail-safe — a transient access failure must never silently remove a critical finding). This gate runs BEFORE the REM-FIX scope decision in §remediation-and-research, so CRITICAL_ONLY / ALL_ISSUES scope is computed over validated findings only.

Inline no-subagent execution (FALLBACK — not the default)

The default execution model is per-phase subagent dispatch: every phase runs in a fresh-context agent via the dispatcher (§7), and that remains the default whenever the Task/Agent primitive is available AND the work is separable. The fallback below is a bounded degrade mode, NOT a shortcut to reach for when dispatch feels heavy. Prefer subagents. Only enter inline mode on one of the two triggers, and record which one in status_history.

Enter inline mode when EITHER trigger holds:

1. Primitive unavailable (graceful degrade): the host harness does not expose the Task/Agent primitive (no Agent(...) dispatch path, or TaskCreate/TaskList are absent). Without it the router cannot spawn phase agents at all; rather than be inoperative, it executes the plan itself.
2. Tightly-coupled work (anti-thrash): the phases are so coupled that isolated phase agents would thrash — they cannot share in-flight state (e.g. a builder and its verifier must observe the same uncommitted in-memory/scratch state, or a phase boundary cannot be expressed as a self-contained scaffold without re-deriving most of the prior phase). Splitting such work across isolated agents loses the shared state at every handoff. When the §5 Intent Readiness Gate shows the phases cannot be cleanly decomposed into self-contained scaffolds, that is this trigger.

What changes vs. default: the ROUTER executes each phase's work inline, in the main session, instead of spawning the phase agent. Walk the same task graph in the same order the dispatcher would. Lose the subagent isolation — KEEP every gate.

What does NOT change (the gates stay fail-closed):

• Run phase_exit_gate at each phase boundary exactly as in the default loop step 6 — if the phase is not complete, persist phase_status={partial|blocked} and stop. No phase advances on prose.
• Persist structured results into the workflow artifact, including results.baseline and the per-phase results the spawned agent would have written. The artifact remains the source of truth; do not rely on conversation narrative.
• Compute the clean-baseline diff the same way: record the baseline before the build phase, and at verification diff the working tree against it so the verifier checks only this workflow's changes.
• Run an inline verification pass in place of spawning integration-verifier: the router itself applies the integration-verifier's checks (run the scenarios, capture Expected/Actual evidence per scenario, reconcile SCENARIOS_TOTAL/PASSED/FAILED, and honor the REVERT authority) and writes the same scenario-accounting into the artifact that §8 post-agent validation would parse. The point is to lose the subagent, not the verification — incomplete or contradictory evidence still sets quality.convergence_state=needs_iteration and stops on the remediation gate.
• All §14 hard rules still bind: never report pass/fixed/complete without confirming the verification evidence, never exceed the 3-cycle remediation limit without a human checkpoint, fail closed on ambiguity or skipped work.

The cost — be disciplined about it: inline mode forfeits fresh-context isolation. The router now carries the build, review, and verify context in one session, so context can bleed across phases (the very pollution subagents prevent). Counter it: between phases, re-ground from the workflow artifact rather than from earlier turns; include only the current-phase objective and live evidence when reasoning about a phase; treat completed-phase narrative as stale. If the session context grows large enough to threaten this discipline, prefer returning to subagent dispatch over pushing further inline.

Mode bookkeeping: persist execution_mode="inline_fallback" and inline_fallback_reason={primitive_unavailable|tightly_coupled} in the workflow artifact, and log an event=inline_fallback_entered entry in .cc10x/workflows/{wf}.events.jsonl. If the primitive becomes available again and the remaining work is separable, the router MAY resume default subagent dispatch for later phases; log event=inline_fallback_exited.

13. Memory Finalization

The memory task executes inline only. Never spawn it as a sub-agent.

The memory task:

• Reads the workflow artifact plus its own description payload, not conversation history.
• Persists learnings to:
  • activeContext.md ## Learnings
  • patterns.md ## Common Gotchas
  • progress.md ## Verification
• Writes deferred items as [Deferred]: ... under patterns.md ## Common Gotchas.
• Replaces progress.md ## Tasks with the active workflow snapshot.
• Keeps only the most recent 10 items in progress.md ## Completed.
• Removes the matching [cc10x-internal] memory_task_id line from activeContext.md ## References.
• Knowledge compounding check (BUILD/DEBUG only): before the final write, evaluate whether this workflow's evidence crosses the solution-doc threshold: (a) the debug attempt count in activeContext.md for this wf: reached 3+ [DEBUG-N]: entries before resolving, OR (b) the reviewer/hunter blast-radius scan touched 3+ files with the same defect pattern, OR (c) the winning fix contradicts a documented assumption in patterns.md. If any condition is true, write docs/solutions/{category}/{slug}.md using the format in cc10x:memory-and-handoff (Problem / What Didn't Work / Solution / Why / Prevention), then reference it from activeContext.md ## Learnings. If none apply, skip — do not create a solution doc for mechanical fixes.
• If any artifact or memory write fails, stop immediately. Never advance the workflow after a failed persistence write.

For PLAN:

• Ensure - Plan: {plan_file} remains correct in activeContext.md ## References.
• Ensure - Design: {design_file} remains correct in activeContext.md ## References when a design exists.
• If a plan exists, record Plan saved: {plan_file} in activeContext.md ## Recent Changes.
• If a plan exists, set activeContext.md ## Next Steps to 1. Execute plan: {plan_file} unless the workflow ended in clarification-needed state.

For DEBUG:

• Preserve the latest [DEBUG-RESET: wf:{workflow_uuid}] section in ## Recent Changes and summarize the final result beneath it.

14. Hard Rules

• Router must run in the main Claude Code session, never inside a sub-agent — sub-agents cannot open user gates or spawn the phase agents.
• Router is the only orchestration state owner. Agents may propose remediation or next actions, but only the router creates, blocks, unblocks, reuses, or completes orchestration tasks.
• Never stop after one agent if the workflow chain has more runnable tasks.
• Never rely on prose when wf:, kind:, origin:, phase:, or scope: can answer the question.
• Never use an unscoped task lookup in critical paths.
• Never treat stored task IDs as durable truth across workflows.
• Never spawn Memory Update as a sub-agent — a sub-agent lacks the captured payload and the memory files' session context.
• Never create CC10X TODO: tasks. Non-blocking discoveries go into **Deferred:** memory notes.
• Never let REVIEW create implementation tasks without an explicit router/user transition into BUILD.
• Never report a workflow outcome (pass, fixed, complete) to the user without first confirming the verification evidence that supports that claim. "I believe it works" is not evidence. [EASY TO MISS: "I ran the tests and they passed" without showing command output, exit codes, or scenario evidence is also not evidence. Require concrete proof artifacts, not agent assertions.]
• Never let a remediation loop reach 3 cycles without a human checkpoint (the >= 3 circuit breaker in references/remediation-and-research.md is the single definition). Drift accumulates silently in long chains.
• Only parallelize agents whose file-write surfaces do not overlap. Reviewer and hunter are read-only and safe to parallelize. Two write agents on overlapping files must be serialized. [EASY TO MISS: Each parallel agent must have a distinct phase value and unique task description. Identical prompts cause agents to duplicate work or silently clobber each other's output.]
• Agents must never inherit raw conversation context. They receive only the structured scaffold from the dispatcher. Leaking conversation history into agent prompts causes scope pollution and non-reproducible behavior.
• Maintain professional objectivity in all routing decisions. Do not rationalize a failing workflow as "close enough" or downgrade critical findings to avoid remediation. The router exists to enforce quality, not to please.
• DIFF_DRIVEN_DOCS: skip in Session Settings disables doc-syncer for projects that manage documentation separately; when present, skip build-doc-sync task creation and block Memory Update on directly.

Capability-offer interaction principle

Optional, cost-bearing capabilities (worktree isolation, research accelerators / web+github researchers, the BUILD-DONE finishing menu) are offered under restraint:

• Offer only when warranted by the actual task, never reflexively.
• Put the offer in its OWN message — just the offer, nothing else bundled in — so it is easy to decline without derailing the work.
• Be honest about cost: name that the capability is token-/cost-intensive or slower when it is.
• NEVER re-offer a capability once the user has declined it, unless the user raises it again themselves. A declined offer is a closed decision for the rest of the session.
