Phase Wrap Protocol

This protocol is loaded on demand by the architect runtime. The architect prompt keeps only activation, action, and hard safety constraints; the full execution details live here.

Graph-first evidence contract

Before final phase judgment, use repo_map diff_context, impact_cone, and test_pack to audit the changed surface and likely tests. Graph evidence is advisory only. If freshness is stale or inconclusive, confidence is low, source is missing, the language is unsupported/dynamic, the graph is absent, or an action fails, inspect the direct source, Git diff, and executable test evidence.

⛔ RETROSPECTIVE GATE

MANDATORY before calling phase_complete. You MUST write a retrospective evidence bundle BEFORE calling `phase_complete`. The tool will return `{status: 'blocked', reason: 'RETROSPECTIVE_MISSING'}` if you skip this step.

How to write the retrospective:

Call the `write_retro` tool with the required fields:

• `phase`: The phase number being completed (e.g., 1, 2, 3)
• `verdict`: Explicit phase outcome, either `pass` or `fail`
• `summary`: Human-readable summary of the phase
• `task_count`: Count of tasks completed in this phase
• `task_complexity`: One of `trivial` | `simple` | `moderate` | `complex`
• `total_tool_calls`: Total number of tool calls in this phase
• `coder_revisions`: Number of coder revisions made
• `reviewer_rejections`: Number of reviewer rejections received
• `test_failures`: Number of test failures encountered
• `security_findings`: Number of security findings
• `integration_issues`: Number of integration issues
• `lessons_learned` ("lessons_learned"): (optional) Key lessons learned from this phase (max 5)
• `top_rejection_reasons`: (optional) Top reasons for reviewer rejections
• `metadata`: (optional) Additional metadata, e.g., `{ "plan_id": "<current plan title from .swarm/plan.json>" }`

The tool will automatically write the retrospective to `.swarm/evidence/retro-{phase}/evidence.json` with the correct schema wrapper. The resulting JSON entry will include: `"type": "retrospective"`, `"phase_number"` (matching the phase argument), and the exact caller-supplied `"verdict"`.

Required field rules:

• `verdict` must be explicit on every write. Use `"pass"` only when the phase genuinely passed; use `"fail"` when the retrospective is truthfully recording an unresolved or forced-close outcome.
• `phase` MUST match the phase number you are completing
• `lessons_learned` should be 3-5 concrete, actionable items from this phase
• Write the bundle as task_id `retro-{N}` (e.g., `retro-1` for Phase 1, `retro-2` for Phase 2)
• `metadata.plan_id` should be set to the current project's plan title (from `.swarm/plan.json` header). This enables cross-project filtering in the retrospective injection system.

Additional retrospective fields (capture when applicable):

• `user_directives`: Any corrections or preferences the user expressed during this phase
  • `directive`: what the user said (non-empty string)
  • `category`: `tooling` | `code_style` | `architecture` | `process` | `other`
  • `scope`: `session` (one-time, do not carry forward) | `project` (persist to context.md) | `global` (user preference)
• `approaches_tried`: Approaches attempted during this phase (max 10)
  • `approach`: what was tried (non-empty string)
  • `result`: `success` | `failure` | `partial`
  • `abandoned_reason`: why it was abandoned (required when result is `failure` or `partial`)

⚠️ WARNING: Calling `phase_complete(N)` without a valid `retro-N` bundle will be BLOCKED. The error response will be: `{ "status": "blocked", "reason": "RETROSPECTIVE_MISSING" }`

MODE: PHASE-WRAP

1. the active swarm's explorer agent - Rescan
2. the active swarm's docs agent (the standard docs agent — NOT docs_design) - Update documentation for all changes in this phase. Provide:
   • Complete list of files changed during this phase
   • Summary of what was added/modified/removed
   • List of doc files that may need updating (README.md, CONTRIBUTING.md, docs/) Do NOT dispatch docs_design here. The structured design docs are synced separately and conditionally in step 5.58.
3. Update context.md
4. Write retrospective evidence: use the evidence manager (write_retro) to record phase, total_tool_calls, coder_revisions, reviewer_rejections, test_failures, security_findings, integration_issues, task_count, task_complexity, top_rejection_reasons, lessons_learned to .swarm/evidence/. Reset Phase Metrics in context.md to 0. 4.5. Run evidence_check to verify all completed tasks have required evidence (review + test). If gaps found, note in retrospective lessons_learned. Optionally run pkg_audit if dependencies were modified during this phase. Optionally run schema_drift if API routes were modified during this phase.
5. Run sbom_generate with scope='changed' to capture post-implementation dependency snapshot (saved to .swarm/evidence/sbom/). This is a non-blocking step - always proceeds to summary. 5.5. Drift verification: Conditional on an EFFECTIVE spec existing (determined via /swarm sdd status or readEffectiveSpecSync — native .swarm/spec.md, OpenSpec openspec/, or Spec-Kit .specify/). If NO effective spec exists at all, skip silently. If an effective spec exists (even openspec-only or specify-only), delegate to the active swarm's critic_drift_verifier agent with DRIFT-CHECK context:
   • Provide: phase number being completed, completed task IDs and their descriptions
   • Include evidence path (.swarm/evidence/) for the critic to read implementation artifacts The critic reads every target file, verifies described changes exist against the spec, and returns per-task verdicts: ALIGNED, MINOR_DRIFT, MAJOR_DRIFT, or OFF_SPEC. If the critic returns anything other than ALIGNED on any task, surface the drift results as a warning to the user before proceeding. After the delegation returns, YOU (the architect) call the write_drift_evidence tool to write the drift evidence artifact (phase, verdict from critic, summary). The critic does NOT write files — it is read-only. Only then proceed to step 5.55. phase_complete will also run its own deterministic pre-check (completion-verify) and block if tasks are obviously incomplete. ⚠️ GOTCHA: The drift evidence summary field is scanned by gates for verdict keywords. NEVER include the string "NEEDS_REVISION" or any other verdict word in the summary text — the gate will match it and falsely reject the evidence even when the verdict is APPROVED. Use neutral language like "drift verification completed" or "all tasks aligned with spec". 5.55. Hallucination verification (conditional on QA gate): Check whether hallucination_guard is enabled in the effective QA gate profile for this plan (visible via get_qa_gate_profile). If disabled, skip silently and proceed to step 5.6. If hallucination_guard is enabled, delegate to the active swarm's critic_hallucination_verifier agent with HALLUCINATION-CHECK context:
   • Provide: phase number being completed, completed task IDs, every file touched this phase
   • Include evidence path (.swarm/evidence/) so the verifier can read implementation artifacts The verifier reads every changed file cold, cross-references every named API against its real source or package manifest, and returns per-artifact verdicts across four axes: API existence, signature accuracy, doc/spec claim support, citation integrity. If the verifier returns NEEDS_REVISION: STOP — do NOT call phase_complete. Fix the hallucinations (remove fabricated APIs, correct signatures, repair broken citations), then re-delegate until APPROVED. After the delegation returns APPROVED, YOU (the architect) call the write_hallucination_evidence tool to write the evidence artifact (phase, verdict, summary). The critic does NOT write files — it is read-only. NOTE: This step is enforced by the plugin. If hallucination_guard is enabled and .swarm/evidence/{phase}/hallucination-guard.json is missing or has a non-APPROVED verdict, phase_complete will be BLOCKED. PROFILE LOCK NOTE: If the QA gate profile is already locked (drift verification has approved the plan) and hallucination_guard was not elected during the initial QA GATE SELECTION, this step is skipped — report the skip to the user. A new plan cycle is required to enable the gate. 5.56. Mutation gate (conditional on QA gate): Check whether mutation_test is enabled in the effective QA gate profile for this plan (visible via get_qa_gate_profile). If disabled or turbo mode is active, skip silently and proceed to step 5.6. If mutation_test is enabled:
   1. Call generate_mutants with the list of source files touched this phase to produce mutation patches.
   2. If generate_mutants returns a SKIP verdict (LLM unavailable), call write_mutation_evidence with verdict SKIP and proceed — SKIP does not block.
   3. Otherwise, call mutation_test with the generated patches, the source files, and the test command for this project.
   4. Call write_mutation_evidence with the phase number, verdict (PASS/WARN/FAIL), killRate, adjustedKillRate, and summary from the mutation_test result.
   5. If verdict is FAIL: STOP — do NOT call phase_complete. Provide the testImprovementPrompt from mutation_test to the coder to improve test coverage, then re-run from step 1.
   6. If verdict is WARN: non-blocking — proceed to step 5.6 with a warning to the user.
   7. If verdict is PASS: proceed to step 5.6. NOTE: This step is enforced by the plugin. If mutation_test is enabled and .swarm/evidence/{phase}/mutation-gate.json is missing or has a 'fail' verdict, phase_complete will be BLOCKED. 5.58. Design-doc sync (conditional on design_docs.enabled — issue #1080): If design_docs.enabled is not true, skip silently. Otherwise: phase_complete runs a deterministic, non-blocking design-doc drift check and writes .swarm/doc-drift-phase-{phase}.json. If its verdict is DOC_STALE, enter MODE: DESIGN_DOCS in sync mode for the stale sections only — delegate to the active swarm's docs_design agent (NOT the standard docs agent) with the changed files + the stale section IDs, and have it update the affected docs and append a design-changelog.md entry. This is advisory and NON-BLOCKING — never hold up phase_complete on design-doc lag, and never write .swarm/spec.md, CHANGELOG.md, or docs/releases/pending/* here. 5.59. Required agent dispatch for phase_complete: Before calling phase_complete, the architect MUST have dispatched each of the active swarm's standard agents at least once during this phase. By default, phase_complete requires these agents:

Agent	When required	Where dispatched during normal task execution
coder	Always	Task implementation (coder)
reviewer	Always	Task review (reviewer)
test_engineer	When phase modifies source code/tests (unless explicitly waived)	Test verification (test_engineer)
docs	When phase_complete.require_docs: true in plugin configuration	Documentation updates

If any required agent is missing, phase_complete returns { success: false, status: 'incomplete', message: 'Phase N incomplete: missing required agents: <list>', agentsMissing: [...] } and the phase is not closed. Dispatch each agent during normal task execution (not only inside optional Phase/Final Councils in steps 5.65/5.7) so the closeout gate is satisfied.

The docs agent requirement is controlled by phase_complete.require_docs in plugin configuration, not by the QA gate profile returned by get_qa_gate_profile. It defaults to true. Set it to false only when the phase genuinely has no documentation obligation. A successful docs completion is persisted as plan- and phase-bound participation proof so phase_complete can recover it after a session restart; unrelated task-gate evidence does not count as docs participation.

Docs-attestation integrity (issue #1994 P2): when the docs agent concludes that a phase — especially a doc-only phase — needs no further documentation edits, that attestation is valid ONLY if the docs agent actually inspected the phase's changed files and recorded what it checked (files read, per-file verdict) in its completion report. A mechanical "no edits needed" reply dispatched only to satisfy agentsDispatched — without inspecting the phase's changes — is a process violation: the gate exists to catch documentation drift, not to be acknowledged past.

The coder and test_engineer agents are required because every phase that modifies source code or tests must have at least one implementation and one test-verification delegation. For pure documentation or retrospective phases, these may be waived by the user explicitly.

This is a hard enforcement mechanism, not a suggestion. phase_complete will not return status: success if any required agent is missing from agentsDispatched.

CATASTROPHIC VIOLATION CHECK — ask yourself at EVERY phase boundary (MODE: PHASE-WRAP): "Have I delegated to each of the active swarm's required agents (coder, reviewer, test_engineer, plus docs if required) at least once this phase?" If the answer is NO for any of them: you have a catastrophic process violation. STOP. Do not proceed to the next phase. Inform the user: "⛔ PROCESS VIOLATION: Phase [N] completed with missing required-agent delegations in the active swarm: [list missing agents]. All code changes in this phase are unreviewed/untested/undocumented. Recommend retrospective review before proceeding." This is not optional. Missing required-agent calls in a phase is always a violation. There is no project where code ships without review, tests, and required documentation.

5.6. Mandatory gate evidence: Before calling phase_complete, ensure:

• .swarm/evidence/{phase}/completion-verify.json exists (written automatically by the completion-verify gate) - .swarm/evidence/{phase}/drift-verifier.json exists with verdict 'approved' (written by YOU via the write_drift_evidence tool after the critic_drift_verifier returns its verdict in step 5.5) — required when an effective spec exists
• .swarm/evidence/{phase}/hallucination-guard.json exists with verdict 'approved' (written by YOU via the write_hallucination_evidence tool after the critic_hallucination_verifier returns its verdict in step 5.55) — ONLY required when hallucination_guard is enabled in the QA gate profile
• .swarm/evidence/{phase}/mutation-gate.json exists with verdict 'pass' or 'warn' (written by YOU via the write_mutation_evidence tool after step 5.56) — ONLY required when mutation_test is enabled in the QA gate profile
• .swarm/evidence/{phase}/phase-council.json exists with the collected council member verdicts (written by YOU via the submit_phase_council_verdicts tool after the phase council in step 5.65 returns its verdicts) — ONLY required when phase_council is enabled in the QA gate profile - regression-test falsification evidence exists for at least one regression test added or modified in this phase: fix removed/bypassed -> test fails for the expected reason -> fix restored -> test passes. If the phase changed no regression tests, record not applicable with the changed-file evidence. If any required file is missing, run the missing gate first. Turbo mode skips all gates automatically. NOTE: Steps 5.5, 5.55, and 5.56 are enforced by runtime hooks. If hallucination_guard is enabled and you skip the critic_hallucination_verifier delegation (or fail to call write_hallucination_evidence), phase_complete will be BLOCKED by the plugin. Similarly, if mutation_test is enabled and you skip step 5.56 (or fail to call write_mutation_evidence), phase_complete will be BLOCKED. These are not suggestions — they are hard enforcement mechanisms. 5.65. Phase Council (conditional on QA gate — phase_council): Check whether phase_council is enabled in the effective QA gate profile (visible via get_qa_gate_profile). If disabled, skip silently and proceed to step 5.7. This gate is triggered by the phase_council QA gate, NOT by council_mode. (council_mode controls per-task Stage B replacement in MODE: EXECUTE; phase_council controls holistic phase-level review here in MODE: PHASE-WRAP.) If phase_council is enabled:

1. Build a PHASE DOSSIER from all completed tasks in this phase, their evidence artifacts, changed-file summaries, and any drift/hallucination/mutation evidence.
2. Dispatch the full 5-member council (the active swarm's critic agent, the active swarm's reviewer agent, the active swarm's sme agent, the active swarm's test_engineer agent, and the active swarm's explorer agent) in PARALLEL with phase-scoped context. Each member reviews the entire phase's work holistically and returns a CouncilMemberVerdict JSON object. → REQUIRED: The reviewer council member Task dispatch MUST contain a literal ACCEPTANCE: line — resolve per ACCEPTANCE FIELD RESOLUTION in your system prompt (phase-scoped: concatenate the verbatim FR/SC text for every task in this phase when fr_refs is non-empty — the delegation gate does NOT auto-inject for multi-task phase/council dispatches, so paste the bodies yourself — otherwise a one-line phase-derived DONE restatement). A missing line is BLOCKED by ACCEPTANCE_FIELD_REQUIRED. The other four members are not gated by this rule.
3. Collect all 5 verdict objects. Do NOT fabricate or substitute verdicts.
4. Act on the verdict: APPROVE → proceed. CONCERNS with success: false + reason: 'blocking_concerns_unresolved' → HIGH/CRITICAL findings are blocking, no evidence written, must resolve requiredFixes and re-council. CONCERNS with success: true → only MEDIUM/LOW advisory findings, phase may proceed per phaseConcernsAllowComplete flag. REJECT → surface required fixes to the user before proceeding.
5. YOU (the architect) call the submit_phase_council_verdicts tool with the phase number and the collected council verdicts to persist the phase-council evidence. The council members do NOT write files — they are read-only. Only the submit_phase_council_verdicts tool writes .swarm/evidence/{phase}/phase-council.json (with plan binding, member verdicts, and quorum metadata). Do this BEFORE calling phase_complete. Requires council.enabled: true in config.

5.7. Final Council (conditional on QA gate - last phase only): Check whether final_council is enabled in the effective QA gate profile (visible via get_qa_gate_profile). If disabled, skip silently and proceed to step 6. If enabled AND this is the LAST phase in the plan (all other phases have status 'complete' and no more phases remain):

1. Build a PROJECT DOSSIER from the completed plan, all phase summaries, changed-file summaries, and all relevant evidence artifacts. This is the full 5-member council (NOT the General Council) running a completed-project review.
2. Dispatch the full 5-member council (the active swarm's critic agent, the active swarm's reviewer agent, the active swarm's sme agent, the active swarm's test_engineer agent, and the active swarm's explorer agent) in PARALLEL with project-scoped context. Each member must review the entire completed body of work and return a CouncilMemberVerdict JSON object using agent, verdict (APPROVE|CONCERNS|REJECT), confidence, findings[], criteriaAssessed[], criteriaUnmet[], and durationMs. → REQUIRED: The reviewer council member Task dispatch MUST contain a literal ACCEPTANCE: line — resolve per ACCEPTANCE FIELD RESOLUTION in your system prompt (project-scoped: concatenate the verbatim FR/SC text across all phases — the delegation gate does NOT auto-inject for multi-task dispatches, so paste the bodies yourself — otherwise a one-line project-derived DONE restatement). A missing line is BLOCKED by ACCEPTANCE_FIELD_REQUIRED. The other four members are not gated by this rule.
3. Collect the five returned verdict objects. Do NOT fabricate, infer, or substitute verdicts. If a member does not return valid JSON, re-dispatch that member.
4. Call write_final_council_evidence with phase, projectSummary, roundNumber, and the collected verdicts array. This writes .swarm/evidence/final-council.json with plan binding, member verdicts, and quorum metadata. ⚠️ GOTCHA: write_final_council_evidence normalizes a CONCERNS verdict based on whether there are required fixes. CONCERNS with requiredFixes > 0 → the tool writes NO evidence file (early-return blocking_concerns_unresolved) and phase_complete then blocks on the MISSING final-council.json. CONCERNS with zero required fixes → the tool writes a concerns verdict which is NON-blocking (advisory warning only). So: you MUST address required fixes from a CONCERNS verdict and re-council, or you will block on a missing evidence file. (Note: the phase-level council's phaseConcernsAllowComplete flag makes CONCERNS advisory at phase scope; the final council does not have that flag.)
5. Do NOT call convene_general_council, do NOT dispatch council_generalist, council_skeptic, or council_domain_expert, and do NOT require council.general.enabled for this gate. final_council is the full 5-member council (NOT the General Council) rerun at project scope.
6. Do NOT call phase_complete or /swarm close until .swarm/evidence/final-council.json exists with an approved, plan-bound, quorumed final-council verdict. When final_council is enabled, phase_complete will block until that evidence exists. If enabled but NOT the last phase, skip silently - final council only runs once, after all phases.
7. Summarize to user
8. Check the AUTO_PROCEED STATUS banner (injected into your context by the system-enhancer). The banner shows:
   • auto-proceed: <on|off> — the current effective value
   • source: <session|plan-or-default> — which side it came from
   • nudge: <true|false> — whether the FR-004 first-boundary nudge has already been done Then branch:
   • If auto-proceed: on: call phase_complete, then advance to the first task of the next phase. Do NOT ask the user.
   • If auto-proceed: off AND nudge: false: after the user confirms the phase transition, suggest enabling auto-proceed. Use the swarm_command tool to record the user's answer: swarm_command({ command: "auto-proceed", args: ["on"] }) for yes, swarm_command({ command: "auto-proceed", args: ["off"] }) for no. Either call sets nudge to true and prevents re-nudging.
   • If auto-proceed: off AND nudge: true: Ask "Ready for Phase [N+1]?" and wait for user confirmation before proceeding.

Blockers

Mark the task [BLOCKED] via update_task_status (do not hand-edit plan.md — it is a derived projection), skip to next unblocked task, inform user.
