Flag Parsing
Parse $ARGUMENTS for flags BEFORE input detection:
| Flag | Effect |
|---|---|
-n, --noask | Skip all user questions, auto-approve defaults |
Strip flag from $ARGUMENTS. Remaining text = path.
Workflow (SPEC input)
0. Check Adapted Templates (REQUIRED FIRST)
EXECUTE using Bash tool:
TMPL_DIR=".claude/tasks/templates"
PLUGIN_TMPL="$BC_PLUGIN_ROOT/skills/setup/templates"
echo "--- Project templates ---"
test -f "$TMPL_DIR/PLAN.md.template" && echo "PLAN.md.template OK" || echo "PLAN.md.template MISSING"
test -f "$TMPL_DIR/phase.md.template" && echo "phase.md.template OK" || echo "phase.md.template MISSING"
test -f "$TMPL_DIR/phase-verify.md.template" && echo "phase-verify.md.template OK" || echo "phase-verify.md.template MISSING"
test -f "$TMPL_DIR/phase-final-review.md.template" && echo "phase-final-review.md.template OK" || echo "phase-final-review.md.template MISSING"
test -f "$TMPL_DIR/phase-fix.md.template" && echo "phase-fix.md.template OK" || echo "phase-fix.md.template MISSING"
echo "--- Plugin fallback templates ---"
test -f "$PLUGIN_TMPL/PLAN.md.template" && echo "PLAN.md.template FALLBACK OK" || echo "PLAN.md.template FALLBACK MISSING"
test -f "$PLUGIN_TMPL/phase.md.template" && echo "phase.md.template FALLBACK OK" || echo "phase.md.template FALLBACK MISSING"
test -f "$PLUGIN_TMPL/phase-verify.md.template" && echo "phase-verify.md.template FALLBACK OK" || echo "phase-verify.md.template FALLBACK MISSING"
test -f "$PLUGIN_TMPL/phase-final-review.md.template" && echo "phase-final-review.md.template FALLBACK OK" || echo "phase-final-review.md.template FALLBACK MISSING"
test -f "$PLUGIN_TMPL/phase-fix.md.template" && echo "phase-fix.md.template FALLBACK OK" || echo "phase-fix.md.template FALLBACK MISSING"
Template resolution order:
- Project templates:
.claude/tasks/templates/{name}.template(adapted by/brewcode:setup) - Plugin fallback:
$BC_PLUGIN_ROOT/skills/setup/templates/{name}.template
STOP if BOTH locations MISSING for any template — Run
/brewcode:setupfirst to get v3 templates. If project templates missing but plugin fallback exists: WARN “Re-run /brewcode:setup for v3 project-adapted templates. Using plugin defaults.”
1. Read SPEC
- Resolve input path per Input Detection table
- Read SPEC.md from task directory
- Extract: goal, requirements, analysis, context files, risks, decisions
2. Scan Project for Reference Examples
- Find 1-2 canonical files per expected phase type (controller, service, test, etc.)
- These become Reference Examples (R1, R2…) in PLAN.md
3. Generate Phase Breakdown (5-12 phases)
Based on SPEC analysis and project structure:
- Each phase = one logical unit of work
- Dependencies between phases identified
- Agents assigned per phase
- Verification phases (NV) after each execution phase
- Final Review (FR) as last phase
4. Present Phases to User (AskUserQuestion)
If --noask: Skip. Auto-approve all phases.
Otherwise: Use AskUserQuestion to present the proposed phase split:
- Phase count and descriptions
- Agent assignments
- Dependency chain
- User can approve, adjust, or request changes
5. Generate Artifacts
Read templates per resolution order from Step 0 (project first, plugin fallback second).
5.1 Create directory structure
.claude/tasks/{TS}_{NAME}_task/
├── phases/ <-- individual phase files
├── artifacts/
├── backup/
├── KNOWLEDGE.jsonl (0-byte empty file)
└── PLAN.md (slim, with Phase Registry)
EXECUTE using Bash tool:
TASK_DIR=".claude/tasks/{TS}_{NAME}_task"
mkdir -p "$TASK_DIR/phases" "$TASK_DIR/artifacts" "$TASK_DIR/backup"
touch "$TASK_DIR/KNOWLEDGE.jsonl"
5.2 Generate phase files (from templates)
For EACH execution phase (1, 2, 3, …):
- Read
phase.md.template - Fill placeholders with SPEC-derived content:
{PHASE_NUM}— phase number{PHASE_NAME}— descriptive name (kebab-case for filename, Title Case for heading){AGENT}— assigned agent{AGENT_ROLE}— one-line agent role description{OBJECTIVE}— concrete objective from SPEC analysis{CONTEXT_FILES}— table rows: files the agent needs to read/modify{REFERENCES}— table rows: reference examples, docs, existing patterns{TASK_LIST}— numbered task list with specific, actionable items{CONSTRAINTS}— project-specific constraints (from SPEC + project rules){EXIT_CRITERIA}— measurable exit criteria (builds, tests pass, lint clean, etc.){ARTIFACT_DIR}— e.g.,1-1e(Phase 1 Execution, iter 1){ADDITIONAL_ARTIFACTS}— files created/modified by this phase
- Write to:
phases/{N}-{name}.md(e.g.,phases/1-create-entity.md)
For EACH verification phase:
- Read
phase-verify.md.template - Fill placeholders:
{PHASE_NUM}— matches the execution phase being verified{PHASE_NAME}— same name as the execution phase{VERIFY_AGENT}— tester or reviewer{FILES_TO_REVIEW}— files created/modified by the execution phase{VERIFICATION_CHECKLIST}— checklist items derived from exit criteria of execution phase{AGAINST_REFERENCES}— reference examples to compare against{ARTIFACT_DIR}— e.g.,1-1v(Phase 1 Verification, iter 1){AGENT}— same as{VERIFY_AGENT}
- Write to:
phases/{N}V-verify-{name}.md
For Final Review:
- Read
phase-final-review.md.template - Fill placeholders:
{FR_AGENTS}— list of review agents (typically reviewer + tester + architect){COMPLETION_CRITERIA}— from SPEC.md goals/decisions, copied to PLAN.md Completion Criteria{REVIEW_CHECKLIST}— comprehensive checklist covering all phases{FILES_CHANGED}— aggregate of all files created/modified across all phases{ARTIFACT_DIR}—FR-1e(Final Review, iter 1)
- Write to:
phases/FR-final-review.md
5.3 Generate PLAN.md (slim v3 format)
Using PLAN.md.template (project-adapted or plugin fallback):
- Fill Phase Registry table with ALL generated phase files
- Each row references the corresponding
phases/{file}.md - Completion Criteria from SPEC.md decisions/goals
- Agents table from project analysis
- Technology Choices from SPEC analysis
- Role Constraints from project rules
5.4 Technology Choices
For each non-trivial choice (library, pattern, approach):
- Document in PLAN.md under Technology Choices section
- Include rationale + alternatives considered and rejected
- Examples: ORM choice, auth library, caching strategy, test framework
6. Quorum Plan Review (3 agents, mixed expertise)
ONE message with 3 Task calls in PARALLEL:
Task(subagent_type="Plan", prompt="Review PLAN.md and ALL files in phases/ against SPEC requirements. Check Phase Registry completeness and phase file content quality.")
Task(subagent_type="brewcode:architect", prompt="Review PLAN.md and phases/ files: architecture decisions, technology choices, dependencies between phases, context files accuracy")
Task(subagent_type="brewcode:reviewer", prompt="Review PLAN.md and phases/ files: exit criteria measurability, task granularity, risks, verification checklist completeness")
Agent prompt template:
> **Context:** BC_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).
Review PLAN at {PLAN_PATH} and phase files at {TASK_DIR}/phases/ against SPEC at {SPEC_PATH}
Check: Phase Registry matches actual phase files, each phase file has filled content (no unfilled placeholders),
agent assignments match expertise, dependencies correct, exit criteria measurable, risks mitigated
Output: list of remarks with rationale
Quorum rule (2/3): Only remarks confirmed by 2+ agents are accepted.
7. Verification Agent (Traceability Check)
Task(subagent_type="brewcode:reviewer", prompt="
> **Context:** BC_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).
Verify PLAN and phase files cover ALL SPEC requirements:
- Each item from SPEC > Scope > In has at least one phase FILE in phases/
- Each requirement from Original Requirements is addressed in a specific phase file's Tasks section
- Phase Registry in PLAN.md matches actual files in phases/ directory
Output: traceability matrix (requirement -> phase file) + gaps found")
If gaps found: Add missing phase files AND update Phase Registry in PLAN.md before presenting to user in Step 8.
8. Present Review Results (AskUserQuestion)
If --noask: Auto-accept all quorum-confirmed remarks. Fix all in PLAN.md and phase files.
Otherwise: Present confirmed remarks + verification results to user. User approves/rejects each. Fix approved remarks in PLAN.md and phase files.
Workflow (Plan Mode input)
0. Check Templates — same as SPEC workflow Step 0
1. Read Plan File
- Parse
.claude/plans/LATEST.mdor provided plan file - Extract structure, goals, steps
2. Create Task Dir + Scan Project
- Generate timestamp and name slug
- Create
.claude/tasks/{TS}_{NAME}_task/ - Scan project for context files and reference examples
3. Split into Granular Phases (finer than plan)
- Each plan item may become 1-3 phases
- Add verification phases
- Add Final Review phase
4. Present Phases to User (AskUserQuestion)
- Same as SPEC workflow step 4 (respects
--noask)
5. Generate Artifacts
- Same as SPEC workflow Step 5 (phases/, PLAN.md, KNOWLEDGE.jsonl, artifacts/, backup/)
- No SPEC.md in this flow (plan replaces spec)
6. Lightweight Plan Review (2 agents)
ONE message with 2 Task calls in PARALLEL:
Task(subagent_type="brewcode:architect", prompt="Review PLAN.md at {PLAN_PATH} and phases/ files: architecture decisions, phase dependencies, agent assignments")
Task(subagent_type="brewcode:reviewer", prompt="Review PLAN.md at {PLAN_PATH} and phases/ files: phase quality, verification criteria, completeness vs source plan")
Rule: Both agents must confirm a remark for it to be accepted (2/2 consensus). Fix confirmed remarks in PLAN.md and phase files before proceeding.
Update Quick Ref (REQUIRED)
Add task link to TOP of .claude/TASK.md (preserve history):
IF .claude/TASK.md exists:
1. Read existing content
2. Prepend: ".claude/tasks/{TS}_{NAME}_task/PLAN.md\n---\n"
3. Append: existing content
ELSE:
Create with: ".claude/tasks/{TS}_{NAME}_task/PLAN.md"
Validation (REQUIRED)
EXECUTE using Bash tool:
TS_NAME="{TS}_{NAME}"
TASK_DIR=".claude/tasks/${TS_NAME}_task"
echo "=== Structure ==="
test -d "$TASK_DIR" && echo "TASK_DIR" || echo "TASK_DIR MISSING"
test -f "$TASK_DIR/PLAN.md" && echo "PLAN" || echo "PLAN MISSING"
test -f "$TASK_DIR/KNOWLEDGE.jsonl" && echo "KNOWLEDGE" || echo "KNOWLEDGE MISSING"
test -d "$TASK_DIR/artifacts" && echo "ARTIFACTS" || echo "ARTIFACTS MISSING"
test -d "$TASK_DIR/backup" && echo "BACKUP" || echo "BACKUP MISSING"
test -d "$TASK_DIR/phases" && echo "PHASES_DIR" || echo "PHASES_DIR MISSING"
head -1 .claude/TASK.md 2>/dev/null | grep -q "${TS_NAME}" && echo "QUICK_REF" || echo "QUICK_REF MISSING"
echo "=== Phase Registry vs Files ==="
grep -oP 'phases/[^\s|]+\.md' "$TASK_DIR/PLAN.md" | sort -u | while read -r pf; do
test -f "$TASK_DIR/$pf" && echo "OK $pf" || echo "MISSING $pf"
done
echo "=== Phase files on disk ==="
for f in "$TASK_DIR"/phases/*.md; do
test -f "$f" && echo "EXISTS $(basename $f)" || echo "NO PHASE FILES"
done
STOP if any MISSING — Create missing artifacts before proceeding.
