SpecKit Autopilot — Autonomous Execution Engine

Installed Runtime Contract

Installed Claude and Codex surfaces resolve Python 3.11 or newer, invoke [resolved_python, "-m", "speckit_pro_runner"], send one JSON request on stdin, read one JSON response from stdout, and surface stderr diagnostics. Do not add a shell fallback, jq parsing path, Git Bash, WSL, or PowerShell-specific command-language requirement for installed workflows.

Scope

This skill handles autonomous workflow EXECUTION. For methodology questions, SDD philosophy, or learning how SpecKit works, redirect to /speckit-pro:speckit-coach.

You are an orchestrator for SpecKit workflows: read prompts from the workflow file and delegate each phase to a subagent that runs the /speckit-* command. You never run the commands yourself — you spawn, collect results, validate gates, and advance. Your context window auto-compacts; do not stop early, complete all 7 phases.

Architectural Constraint — Main Agent Is The Orchestrator

This skill loads into the main session agent when the user invokes /speckit-pro:speckit-autopilot. Only the main agent can spawn subagents (sub-agent docs: subagents can't nest) AND create Agent Teams (Agent Teams architecture: team-lead = main session). The skill IS the orchestrator at execution time. EVERY dispatch decision — parallel subagents vs sequential vs Agent Team, model routing, lifecycle sequencing — happens HERE. Phase executors are terminal workers; they don't dispatch, don't branch on AGENT_TEAMS_AVAILABLE, don't create teams.

Runtime enforcement is two-tier (Layer 5 verifies both): the hyper-focused single-purpose workers (the consensus analysts, clarify-executor, gate-validator, uat-runbook-author) explicitly deny Agent/TeamCreate/SendMessage via disallowedTools so they stay on their one job; the open workhorse executors (phase-, analyze-, checklist-, implement-executor) keep the operator's full surface — including orchestration tools — and the invariant there is carried by this skill owning all PHASE dispatch plus each executor's terminal-worker prompt, never by a capability block. If this skill is ever loaded inside a subagent context, it MUST refuse rather than orchestrate. Full invariant + implications for new workstreams in references/agent-teams-integration.md §Single orchestrator invariant.

The no-allowlist rule is about agent definitions: Claude agents must omit tools: so they inherit the operator's installed surface. This skill's frontmatter may still declare Claude allowed-tools to authorize the orchestrator's core primitives; that declaration is not an MCP/vendor availability list and does not replace runtime capability discovery.

Prerequisites — Model & Effort

The orchestrator makes gate decisions, synthesizes consensus, and manages a 7-phase workflow. Weak-model orchestration cascades into expensive rework.

Before executing any step, verify:

1. Model: Opus 4.6 or better. On Sonnet/Haiku/older Opus, STOP and instruct: "Autopilot requires Opus 4.6 for reliable orchestration. Please /model opus and re-run."
2. Effort: max (required). On anything less, STOP and instruct: "Autopilot requires max thinking. Please /effort max and re-run."

Non-negotiable. The plugin's policy is max thinking on every agent, regardless of model — quality is the only optimization axis. Every bundled subagent runs at effort: max (or xhigh on Codex). A sub-max orchestrator spawning max subagents wastes the subagents' reasoning — the orchestrator's decisions determine whether subagent work is productive or wasted.

Critical: Execution Rules

These rules are non-negotiable. Follow them exactly.

0. Forbidden skill invocations

<hard_constraints>

Do not invoke grill-me from any autopilot phase or agent — ever.

grill-me is human-in-the-loop only — it uses AskUserQuestion to interview a real user one question at a time. Inside autopilot there is no user available; calling it would block indefinitely or produce low-value automated output that defeats its purpose.

Autopilot's Clarify phase uses /speckit-clarify with the multi-agent consensus protocol — the only sanctioned clarification mechanism inside autopilot. If a phase encounters ambiguity consensus can't resolve, fail the gate and surface to the user. Never escalate to grill-me.

Applies to this skill (the orchestrator), every phase-executor agent, every consensus analyst, the synthesizer, the gate-validator, and any other agent spawned during autopilot execution. grill-me is for pre-workflow human alignment via /speckit-pro:speckit-scaffold-spec or /speckit-pro:grill-me only; it must not appear in any phase agent's tool call history.

</hard_constraints>

0.5 Static Tier-2 relocation suggestions only

<hard_constraints>

Autopilot may surface Tier-2 PROCESS relocation guidance for thawed legacy specs, but it must never execute relocation mutation from any autopilot phase, subagent, or post-implementation step.

</hard_constraints>

At startup and when evaluating the active workflow target, inspect candidate state directly. Suggest relocation only for a thawed in-scope legacy spec that has root PROCESS allow-list artifacts or matching docs-side scaffold artifacts.

For an eligible candidate, print the concrete specs/<spec-dir> value and say that relocation remains manual operator work outside autopilot. Describe any write as a follow-up after review and a clean worktree. Suppress the suggestion and report the reason for:

• frozen/in-flight specs named by .specify/feature.json
• invalid active-feature state
• already-current specs with SPEC-MOC.md structureVersion: 1
• already-normalized specs whose PROCESS artifacts are under .process/
• candidates with no relocatable PROCESS artifacts
• out-of-scope non_speckit_namespace and date_named_legacy_namespace candidates

1. Subagent per phase

For each phase, spawn a foreground subagent via the Agent tool. The subagent runs the /speckit-* command and returns a summary. You (the parent) receive the result as a tool call response, which keeps your agent loop alive.

Why: Claude Code's agent loop terminates when a response has no tool calls. A direct Skill() call loads the command into YOUR context; the command's "report completion" instruction makes you output plain text and the loop dies. With subagents, the command runs in isolated context — the result returns as a tool response and your loop continues.

Third-party skills: the same hazard applies when capability discovery selects an installed skill you invoke via Skill() — its completion text can end your loop. Capture the skill's result as evidence and continue with a follow-up tool call; never treat a third-party skill's completion text as your own terminal output.

2. Use phase-specific executor agents

Each phase type has its own specialized executor agent. All noise stays in the subagent's context; the parent receives only a summary.

Phase	Agent	Why specialized
Specify, Plan, Tasks	speckit-pro:phase-executor	Heavy reasoning (Specify, Plan); mechanical for Tasks. Single skill invocation, single summary.
Clarify	speckit-pro:clarify-executor	Read-only question set; parent answers and edits
Checklist	speckit-pro:checklist-executor	Must run checklist AND remediate gaps with research
Analyze	speckit-pro:analyze-executor	Must run analysis AND remediate ALL findings with research
Implement	per-task routing	Task-level dispatch: routes each task to best-fit agent with TDD protocol

Full Agent(...) prompt template + per-phase prefixes live in references/phase-execution.md §Subagent Delegation.

Agent-type namespacing (required): the prefix requirement applies to every speckit-pro bundled agent id used as a subagent_type value — the executors above and the analysts in the routing tables below dispatch with their speckit-pro: prefix (speckit-pro:phase-executor, speckit-pro:clarify-executor, …). The runtime resolves plugin agents by their namespaced id, so a bare subagent_type: "phase-executor" fails immediately with Agent type 'phase-executor' not found. Identifiers that take no prefix: general-purpose (a built-in agent), and entries in the tables that are not bundled agent ids — the PROJECT_IMPLEMENTATION_AGENT variable (resolved to a host-project agent, with speckit-pro:phase-executor as its fallback value) and orchestrator-direct (the orchestrator acting directly, not a subagent).

3. Task list first

Before executing any phase, create a granular task list using TaskCreate. The task list drives the loop — after each subagent returns, check it to know what's next. See Step 1.1 for the full naming pattern and rules.

4. Multi-prompt phases

Clarify and Checklist have multiple prompts in the workflow file. Spawn a separate subagent for each prompt and run the two-layer resolution (Rule 6) after each one BEFORE spawning the next — later sessions/domains may depend on earlier resolved items. Do not batch all sessions and check for markers only at the end.

Per-phase flow templates (per-session for Clarify, per-domain for Checklist) live in references/phase-execution.md §Phase-by-Phase Execution.

5. Clarify — executor returns questions to parent

The clarify-executor is read-only. It does not invoke /speckit-clarify, does not wait on a user, and does not edit artifacts. It inspects the workflow prompt, feature spec, and repo evidence, then returns a Clarify Question Set containing up to 5 prioritized questions, recommended answers, evidence, and suggested artifact updates.

The parent orchestrator answers the returned questions in the main session, applies the spec/workflow/state edits, then checks for remaining [NEEDS CLARIFICATION] markers and resolves unresolved items via consensus if needed (see Rule 6).

6. Two-layer resolution with category-routed consensus

After EACH executor subagent returns for a consensus phase (Clarify, Checklist, Analyze), run a two-layer resolution process BEFORE spawning the next subagent.

Layer 1 — Executor prepares evidence: Clarify is different from Checklist and Analyze. The clarify-executor returns questions and recommendations to the parent; the parent answers and applies accepted edits. checklist-executor and analyze-executor still resolve most items directly and apply fixes to artifacts. Any item that needs further resolution is flagged in an "Unresolved for consensus" summary section, each prefixed with one or more category tags ([codebase], [spec], [domain], [security], [ambiguous]).

Layer 2 — Category-routed consensus (Tier A): for ALL unresolved items in the phase, batch-dispatch the union of routed analysts in ONE assistant message (run_in_background: true), wait for all, then batch-dispatch ALL synthesizers in ONE message, then apply each synthesizer's Artifact Edit serially (orchestrator's own Edit calls — avoids write contention on spec.md/plan.md/tasks.md). Escape-hatch to Round 2 (remaining analysts, full fan-out + 2-of-3 majority) on [ESCAPE_TO_ROUND_2] or low confidence, also batched. [security] always uses all 3 in Round 1. Full routing table, Round-2 algorithm, batched-dispatch pseudocode, and the "no silently-shipped low-confidence answers" escape-hatch rationale live in references/consensus-protocol.md §Category-Routed Dispatch + §Batched Dispatch.

Consensus rules summary: N=1 high-confidence → use answer; N=2 both-agree → use answer; N=3 2-of-3 or 3-of-3 agree → use majority/unanimous; escape-hatch keyword OR low confidence → Round 2; all-disagree at Round 2 → [HUMAN REVIEW NEEDED] + STOP; [security] → always Round 2 with all 3, never single-routed. Full rules + Logging schema + Re-evaluation trigger live in references/consensus-protocol.md.

Why two layers: Executor handles ~80% directly; category-routed consensus spends model effort only on the perspective(s) the executor identified as relevant. Run after each prompt — later sessions may depend on earlier resolved items.

Input

You receive a workflow file path and optional arguments:

path/to/workflow-file.md [--from-phase specify|clarify|plan|checklist|tasks|analyze|implement] [--spec SPEC-ID]

Step -1 + Step 0: Pre-flight (Archive Sweep + Prerequisites)

Run the pre-flight sequence before any phase work. STOP on failure.

1. Use runner helper operation IDs. Invoke read-only helper behavior through resolved_python -m speckit_pro_runner with one JSON request on stdin; do not rely on plugin-local script files.
2. Archive Sweep — /speckit-archive-run --sweep --current-target <current-spec-dir> on feature/spec branches; add --dry-run on main, release, or any protected integration branch. Skip if the archive extension is absent. Excludes the current target spec.
3. Run prereq helper operations and parse the JSON output of each:

   helper_id=check-prerequisites operation=check-prerequisites mode=read_only
   helper_id=detect-commands operation=detect-commands mode=read_only
   helper_id=detect-presets operation=detect-presets mode=read_only
   

   Record on_feature_branch, PROJECT_COMMANDS, PRESET_CONVENTIONS, and MCP availability into the workflow file. Pass PROJECT_COMMANDS and PRESET_CONVENTIONS to every subagent prompt.
4. Constitution validation — for each principle in .specify/memory/constitution.md, run the appropriate PROJECT_COMMANDS check (typecheck/test/build/lint); update the workflow's Prerequisites table. STOP on any failure.
5. Implementation agent detection — Glob .claude/agents/*.md, match descriptions against implementation keywords; set PROJECT_IMPLEMENTATION_AGENT (fallback: speckit-pro:phase-executor). Also check CLAUDE.md for an explicit agent reference.
6. Load settings + Agent Teams probe — read .claude/speckit-pro.local.md (consensus-mode, gate-failure, auto-commit, security-keywords); record AGENT_TEAMS_AVAILABLE from env+version probe (see prerequisites.md §Step 0.6). 6b. Resolve pre-Implement confidence gate mode — run runner helper resolve-confidence-mode with the invocation argv to resolve the mode for G6.5 (precedence: --strict / --advisory flag in argv > confidence_gate_mode in local config > default advisory). If the script exits 2 (both flags passed), STOP the autopilot before Phase 0 with the conflict message — fail fast on usage errors. Record the resolved value as CONFIDENCE_GATE_MODE for use at G6.5. Do not re-run the resolver at G6.5; G6.5 reads CONFIDENCE_GATE_MODE directly. See Gate Validation §G6.5.
7. Capability enumeration, grounding & feed-down — you are the only component that discovers openly. Before relying on any capability, enumerate what this session actually exposes: surface deferred MCP tools with ToolSearch, and treat the available-skills list as the installed-skill registry. Select best-fit per references/capability-discovery.md — do not assume a fixed set; the user may have installed anything. Your phase and consensus subagents inherit the operator's full installed surface and follow the same directive — read-only roles select only read/research capabilities (their mutation built-ins are denied). Still pass the discovered evidence and capability context a subagent needs directly in its prompt: shared context beats re-discovery. Ground your OWN output (gate decisions, consensus synthesis, generated PR bodies) per references/grounding.md: every external fact you assert must cite a real tool/skill/file result, and you abstain when nothing grounds it.

Plugin agent caveat: permissionMode, hooks, and mcpServers frontmatter are silently ignored on plugin agents. Run the parent session in acceptEdits or bypassPermissions for smooth execution. See references/plugin-limitations.md.

Full per-step details, JSON schemas, capability fallback behavior, and failure-escalation rules: see references/prerequisites.md.

Step 1: Parse Workflow State

Read the workflow file and parse the "Workflow Overview" status table. Find the first phase with status ⏳ Pending or 🔄 In Progress.

If --from-phase is specified, start from that phase regardless of the status table.

If all phases are ✅ Complete, report "All phases complete" and stop.

1.1 Create Progress Task List

After parsing the workflow state, create a granular task list. For multi-prompt phases (Clarify, Checklist), create one task per prompt/session. Every Clarify session, every Checklist domain, and the Analyze phase MUST have a paired Consensus task immediately after (skipped only if the executor reports zero unresolved items).

The full 12-entry Post-Implementation task list and the task naming pattern live in references/task-list-canonical.md. Every entry there MUST appear in the visible progress panel before Phase 1 starts — when an extension is absent, the task still appears marked skipped: <ext-name> not installed.

Verify completeness before starting Phase 1: count the prescribed entries (every Phase, every Consensus, every Post:) and ADD any missing before advancing.

Step 2: Main Execution Loop

For each pending phase, spawn a subagent, collect the result, validate the gate, advance. Every step is a tool call.

PHASES = [specify, clarify, plan, checklist, tasks, analyze, implement]

for phase in PHASES starting from first_pending:
    1. TaskUpdate: phase task → in_progress
    2. Run before_<phase> hooks from .specify/extensions.yml
    3. For each workflow prompt in this phase:
         Agent(subagent_type: <phase executor>, prompt: ...)
    4. Run consensus (Clarify/Checklist/Analyze only) — see Rule 6
    5. Run after_<phase> hooks
    6. Validate gate via gate-validator agent → parse PASS/FAIL
       On FAIL: auto-fix max 2 attempts; then honor gate-failure setting
    7. Update workflow file; auto-commit if configured
         phases 1-6: git add specs/ && git commit
         phase 7:    git add -A && git commit
    7b. After Plan (G3 pass, plan.md exists), run the plan-phase
        reviewability budget with runner helper `estimate-reviewable-loc`,
        guarded against errexit. Branch on JSON `status`
        (pass / over_budget / not_estimated) or the exit code.
        ADVISORY — never blocks, prompts mid-autonomous-run, or
        crashes the run (hard block / re-slicing is PRSG-010).
    8. After Tasks (G5 pass), apply the tasks-phase reviewability
       boundary. Runner helper `reviewability-gate` supports setup mode
       only on the installed runner — tasks mode is deferred, so do not
       invoke it as an active helper. Record the deferred-mode
       diagnostics (helper ID, requested mode, deferral reason) in the
       workflow file, then continue on the fallback evidence chain: the
       setup-mode gate result recorded at scaffold, the plan-phase
       `estimate-reviewable-loc` verdict from step 7b, and any
       operator-ratified split decision in the workflow file.
       In that committed evidence, `pass`, `warn`, honored exception,
       and valid current size-only `block` are marker-planning inputs.
       A valid current size-only block continues into marker planning
       and marker emission; it is not a manual re-slicing stop.
       Preserve correctness stops for malformed/stale marker state,
       failed verification, invalid packet, unsafe output, unusable
       gate evidence, invalid JSON, missing status/mode, stale
       fingerprints, and non-size safety findings.
    8c. After Tasks (G5 pass), run runner helper `atomicity-route`
        for `<feature-dir>`
        and record the emitted JSON decision into the workflow
        file's "## Atomicity Route" section. READ-ONLY + ADVISORY —
        the script writes nothing and never blocks; the SKILL is
        what records it.
    8d. After recording the atomicity route, run the layer planner only
        when route is exactly `split-PR`, and always before Analyze or
        Implement can continue:
        - non-split routes: record `layer_plan.status=skipped` in
          `autopilot-state.json` and the workflow "## Layer Plan" section,
          then continue with route context.
        - split route: run helper operation `plan-layers-feature-dir` for
          `<feature-dir>` and capture stdout, stderr, and exit code.
        - exit 0: parse stdout as the full versioned layer-plan envelope,
          persist it under `layer_plan` in `autopilot-state.json`, write a
          concise workflow "## Layer Plan" summary, carry warnings into the
          implementation context, then continue.
        - exit 1: STOP before implementation and print exactly:
          `STOP: Layer planner returned invalid_plan (exit 1) for <feature-dir>; implementation has not started. Fix tasks.md using the planner diagnostics below, then rerun autopilot from the Layer Plan step.`
          Then show planner diagnostics from stdout/stderr.
        - exit 2: STOP before implementation with a distinct
          `input_error` message and include planner diagnostics.
        This wires NO PR emission or branch creation (PRSG-009 owns that).
    8e. Persist marker planning state when reviewability evidence requires it:
        top-level `pr_marker_plan` in `autopilot-state.json`, mirrored
        workflow evidence, and repo-relative evidence paths. Do not treat
        `tasks.md` as authoritative marker state.
    9. Advance

Full per-phase prompts, dispatch templates, gate validation details, hook events, and the dispatcher-agent table: see references/phase-execution.md.

After all 7 phases pass G7, execute the post-implementation task list. The 12 tasks, detailed prompts, and extension routing live in references/post-implementation.md; the canonical name list is in references/task-list-canonical.md.

⚠️ Use Agent() subagents for ALL post-implementation tasks — NEVER Skill() directly. Rule 1 applies: a Skill() call loads the command into YOUR context and the command's completion text can kill the agent loop, preventing subsequent tasks from running.

Extension availability: Step 0.12 records which extensions are installed in .registry. If an extension is missing, log a warning and mark its task skipped: <ext> not installed — do NOT fail the autopilot. Recommend specify extension add <name> in the warning.

Dynamic task updates: If consensus reveals new questions or remediation adds loops, create additional tasks via TaskCreate.

Phase Dispatch

Every subagent prompt includes the workflow-file prompt plus, when present, PRESET_CONVENTIONS (from Step 0.12) and PROJECT_COMMANDS (from Step 0.11). The full Agent(...) template lives in references/phase-execution.md §Subagent Delegation.

Agent selection:

Phase	subagent_type	Prefix
Specify	speckit-pro:phase-executor	Branch-aware when ON_FEATURE_BRANCH (skip new feature branch creation)
Clarify	speckit-pro:clarify-executor	Read-only — returns a Clarify Question Set; parent answers + applies edits
Plan	speckit-pro:phase-executor	None
Checklist	speckit-pro:checklist-executor	One subagent per domain
Tasks	speckit-pro:phase-executor	None
Analyze	speckit-pro:analyze-executor	None
Implement	per-task routing	TDD protocol + COMPLETED_TASKS — see Implement — Task-Level Dispatch below

Per-phase prefix templates (branch-aware Specify prefix, Clarify question-set contract, multi-prompt fan-out for Clarify sessions and Checklist domains) live in references/phase-execution.md §Phase-by-Phase Execution.

Resolution — After Each Prompt (Main Session)

After EACH executor subagent returns for a consensus phase (Clarify, Checklist, Analyze), apply the two-layer category-routed protocol — Layer 1 marker scan, Layer 2 routed-analyst dispatch with Round 2 escape-hatch, post-resolution per-phase verification, and mandatory Consensus Resolution Log rows. Full protocol, per-phase verification prompts, and canonical log columns live in references/consensus-protocol.md §Phase-Specific Consensus Flows + §Logging.

Implement — Task-Level Dispatch (honors [P] markers)

Phase 7 dispatches each task to the best-fit agent and honors [P] parallel-safe markers from /speckit-tasks for batched parallel execution. Within a phase group, partition tasks into runs: consecutive [P] tasks form a parallel run; non-[P] tasks are singletons. Dispatch each parallel run in ONE assistant message via background subagents. Sequential runs spawn one foreground agent, await, advance. After every parallel run, run TYPECHECK + UNIT_TEST as a safety net; on regression, fall back to serial re-run for that group.

Agent routing:

Task Type	Agent	TDD?
Tests (contract/unit/integration)	speckit-pro:implement-executor	Yes
Domain implementation	PROJECT_IMPLEMENTATION_AGENT	Yes
Research / API investigation	speckit-pro:domain-researcher	No
Verification (build, lint)	orchestrator-direct	No

Every implementation agent receives the TDD protocol from references/tdd-protocol.md. Agent selection is about domain expertise — all follow identical RED-GREEN-REFACTOR discipline.

Full algorithm (parse tasks, partition into runs, route, batched dispatch for [P] runs, accumulate context, verify): see references/phase-execution.md §Phase 7 Step 3.

This is Use site 3 of the Agent Teams integration map — when AGENT_TEAMS_AVAILABLE=true, parallel runs spawn as a team (cross-task mailbox coordination); otherwise batched background subagents in one message (same wall-clock, no team coordination).

Step 3: Post-Implementation

After all 7 phases complete and G7 passes, follow the detailed procedures in references/post-implementation.md:

1. 3.0 Parallel group — auto-routed by AGENT_TEAMS_AVAILABLE (teams vs parallel-subagents)
2. 3.1 Integration Suite — verify spec-specific tests exist, run FULL suite to catch regressions, fix failures
3. Self-Review — mandatory 4-question audit between Integration Suite and the PR body; findings are recorded in the workflow log and reproduced in the PR body. Reporting step — never gates the PR.
4. UAT Runbook Generation — mandatory between Self-Review and the PR body. The runner helper generate-uat-skeleton is registered as deferred, so do not invoke it as an active helper. Reuse a committed source-derived runbook when present; otherwise record the UAT skeleton as skipped with deferred-helper evidence, then spawn the uat-runbook-author subagent only when a skeleton exists. This is fail-open and must be logged.
5. 3.2 PR Creation — final verification, then apply the final reviewability boundary. The runner helper final-reviewability-backstop is registered as deferred, so do not invoke it as an active helper; use current committed reviewability evidence or stop before PR side effects if no current evidence exists. Only pass, warn, honored typed-exception outcomes, or final marker_split with a valid current pr_marker_plan may continue. When a current pr_marker_plan is present, successful PR preparation uses marker-based PR emission even if the final full-diff gate is only pass or warn. A full-diff size block with current marker evidence also proceeds to marker-based PR emission; it is not a manual re-slicing stop. An unexcepted correctness block writes final_reviewability_gate state plus a reslicing_required packet and stops only the unsafe PR side effects. It is not a final answer or operator handoff: read autopilot_continuation, operator_steps, and resume.resume_from, then continue internally through PRSG-007/008/009 until a valid slice PR stack is emitted or a typed exception is committed. Never report completion while autopilot_continuation.required=true; a gate error writes state and stops without a packet. After a proceed result, emit or refresh the feature-local packet at specs/<feature>/.process/pr-packets/<packet-id>.json with pr-packet-output. Run it in dry_run first, then apply only after the packet path, body path, base/head target, title, changed-file scope, verification evidence, UAT text, non-goals, and known gaps are current. pr-packet-output writes the packet JSON and packet-owned body file, and declares the validation-result path; generate-pr-body remains body-only and is not a packet substitute. Run validate-pr-packet-read-only against the emitted packet and consume only the current response data.stdout_json in memory and durable state. Continue only when it reports status=passed, pr_blocked=false, and the response reports writes_state=false. Commit or otherwise checkpoint the packet/body artifacts so the worktree is clean, then run validate-pr-packet-write; apply mode reruns read-only validation before persisting the packet's validation_result_path. Open the PR with packet fields through gh pr create --base --head --title --body-file; never derive the title from the branch, write the body from scratch, pass inline --body, reuse prior validation evidence, or repair invalid packets after creation. Before any single-PR create attempt, run runner helper validate-pr-workflow-contract with the packet title and changed-file list; a nonzero result blocks the aggregate PR path. If the changed files include multi-PR candidate commands or final marker-split evidence for more than one PR, the single-PR path is forbidden. multi-pr-emission may capture a golden_only command plan, but it does not emit packets or execute PRs. Continue only when every required feature-local packet has been emitted or refreshed through pr-packet-output, passes the same read-only validation, and has current persisted validation evidence. Push, create PR, update workflow file. Required evidence prompts: gate status/mode/exit/evidence path, fingerprint status, ordered marker IDs, checkpoints, warnings, final marker_split or marker-plan-ready handoff, packet validation, and PR mappings.
6. 3.3 Review Remediation — schedule /loop to monitor and resolve Copilot/human review comments every 5 minutes

After scheduling the loop, the autopilot is DONE. Report the final summary with PR URL.

Workflow File Update Protocol

After EVERY phase, update the workflow file so it remains the durable source of truth across context compactions and resumes: status table ⏳ → ✅ with summary notes; per-phase Results tables; Constitution Validation table after Specify (initial) and Implement (final); Consensus Resolution Log row per resolution (when consensus was used).

Full per-phase update table and Consensus Resolution Log column schema live in references/workflow-file-protocol.md.

Error Recovery

• Resume: /speckit-pro:speckit-autopilot workflow.md --from-phase <next-pending-phase> — the workflow file persists all state.
• Gate fails after 2 auto-fix attempts: honor gate-failure setting (default stop); on STOP, show gate script output.
• Consensus all-disagree (Round 2): flag [HUMAN REVIEW NEEDED], STOP, and present all 3 perspectives to the user.
• Research/context capability unavailable: use the next acceptable evidence path, record any confidence impact, and escalate only when no acceptable evidence path remains or a true gate fails.
• Context window pressure: keep subagent summaries concise; the workflow file is the durable record (re-read after compaction).

Full details, additional failure modes, and recovery playbooks live in references/error-recovery.md.

Deterministic prerequisite checks, validation, reviewability, routing, payload, and PR-preparation behavior is owned by speckit_pro_runner. Invoke resolved_python -m speckit_pro_runner with one JSON request on stdin and use the registered helper or gate operation IDs below.

• check-prerequisites — Verify CLI, project init, constitution, commands, branch detection, and workflow file readiness (JSON).
• validate-gate — Validate G1-G7 with marker counts and details (JSON).
• confidence-gate — Read the synthesizer's 📊 Confidence: X.XX pre-Implement emit and decide whether Phase 7 may begin.
• resolve-confidence-mode — Resolve the pre-Implement confidence mode from invocation flags, local config, or the advisory default.
• reviewability-gate — Enforce the setup-mode reviewability budget. Tasks and pre-PR modes are deferred for installed workflows; record the deferral and use committed fallback evidence per the guidance above instead of invoking them.
• atomicity-route — Classify whether a feature should remain one PR or split.
• plan-layers-feature-dir — Emit a versioned layer-plan envelope for split routes before implementation.
• estimate-reviewable-loc — Project production reviewable LOC from declared file operations.
• generate-pr-body — golden_only body writer accepting exactly output_path, title, and sections; it writes one Markdown body and does not emit packet JSON, metadata, markers, validation evidence, or PR commands.
• pr-packet-output — golden_only packet emitter accepting structured packet fields; it writes the feature-local packet JSON, packet-owned body file, and declared validation-result path used before PR creation.
• validate-pr-packet-read-only — Validate an existing feature-local packet and return the result in data.stdout_json with writes_state=false; it does not persist validation state.
• validate-pr-packet-write — Rerun read-only packet validation in apply mode, then persist that current passing result to the packet's validation_result_path; do not use caller-supplied or stale validation results.
• validate-pr-workflow-contract — Validate PR title and changed-file scope.
• detect-commands, detect-presets, and count-markers — Provide deterministic command, preset, and marker evidence through runner-owned operation IDs.
• generate-uat-skeleton and final-reviewability-backstop — Registered but deferred for installed workflows; follow the deferred guidance above instead of invoking them.
• relocate-process-artifacts and restack — Registered but deferred with no active invocation contract. Do not invoke them or infer capability from generic runner plumbing.
