Input Handling

Input	Action
$ARGUMENTS empty	Read .claude/TASK.md → first line = path → derive task dir
$ARGUMENTS has text	Use as task description
$ARGUMENTS has path	Read file as task description

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 = description or path.

Naming

• Timestamp: YYYYMMDD_HHMMSS (e.g., 20260208_143052)
• Name slug: lowercase, underscores, from description (e.g., auth_feature)
• Task dir: .claude/tasks/{TIMESTAMP}_{NAME}_task/

Workflow

0. Check Adapted Templates (REQUIRED FIRST)

   EXECUTE using Bash tool:

   test -f .claude/tasks/templates/SPEC.md.template && echo "SPEC.md.template" || echo "SPEC.md.template MISSING"

   STOP if MISSING — Run /brewcode:setup first.

1. Read & Analyze Input

   • Parse $ARGUMENTS per Input Handling table
   • Determine scope: files affected, areas of codebase
   • Identify what needs clarification

2. Clarifying Questions (AskUserQuestion)

   If --noask: Skip. Record in SPEC User Q&A: "Skipped (--noask mode)". Infer scope from description and codebase analysis.

   Otherwise: Use AskUserQuestion tool to ask 1-4 questions about:

   • Scope boundaries (what's in/out)
   • Priority trade-offs (performance vs simplicity, etc.)
   • Constraints (backward compatibility, specific libraries, etc.)
   • Edge cases or ambiguous requirements

   Record all Q&A for the User Q&A section of SPEC.

3. Partition Research Areas (5-10 areas)

   Analyze project and split into logical parts for parallel research:

   | Area | Pattern | Agent |
   |------|---------|-------|
   | Controllers | **/controllers/ | developer |
   | Services | **/services/ | developer |
   | DB/Repos | **/repositories/ | developer |
   | Tests | **/test/ | tester |
   | Config | *.yml, docker-* | developer |
   | Docs | *.md, docs/ | Explore |

   See references/SPEC-creation.md for detailed parallel research instructions.

4. Parallel Research (ONE message, 5-10 agents)

   ONE message with 5-10 Task calls in PARALLEL
   
   Task(subagent_type="Plan", prompt="Analyze architecture...")
   Task(subagent_type="developer", prompt="Analyze services...")
   Task(subagent_type="tester", prompt="Analyze test patterns...")
   Task(subagent_type="reviewer", prompt="Analyze quality...")
   Task(subagent_type="Explore", prompt="Find library docs...")

   Agent prompt template:

   > **Context:** BC_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).
   
   Analyze {AREA} for task: "{TASK_DESCRIPTION}"
   Focus: patterns, reusable code, risks, constraints
   Context files: {FILES_IN_AREA}
   Output: findings (bullets), assets (table), risks, recommendations
   NO large code blocks - use file:line references

5. Consolidate into SPEC

   • Create task directory: .claude/tasks/{TIMESTAMP}_{NAME}_task/
   • Read .claude/tasks/templates/SPEC.md.template (project-adapted)
   • Merge agent findings (deduplicate)
   • Fill SPEC sections per Consolidation Rules in references/SPEC-creation.md
   • Write .claude/tasks/{TIMESTAMP}_{NAME}_task/SPEC.md
   • Include Research table with per-agent findings

6. Present Key Findings (AskUserQuestion)

   If --noask: Skip validation. Auto-approve all findings.

   Otherwise: Use AskUserQuestion to validate with user:

   • Key architectural decisions made
   • Risk assessment and proposed mitigations
   • Any assumptions that need confirmation
   • Completeness check: "Does this cover everything?"

   Incorporate user feedback into SPEC.

7. Review SPEC (reviewer agent + fix loop)

   Task(subagent_type="reviewer", prompt="> **Context:** BC_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook).
   
   Review SPEC at {SPEC_PATH}
   Check: completeness, consistency, feasibility, risks
   Output: list of remarks with severity (critical/major/minor), specific fixes")

   Iteration loop:

   WHILE remarks.critical > 0 OR remarks.major > 0:
     1. Fix all critical/major remarks in SPEC.md
     2. Re-run reviewer

   Exit criteria: No critical/major remarks remaining

Template source: Always from .claude/tasks/templates/ (project), never from plugin base templates directly.

Output

# Spec Created

## Detection

| Field | Value |
|-------|-------|
| Arguments | `{received args}` |
| Input Type | `{text description or file path}` |
| Noask | `{yes or no}` |

## Files Created
- SPEC: .claude/tasks/{TIMESTAMP}_{NAME}_task/SPEC.md
- Task Dir: .claude/tasks/{TIMESTAMP}_{NAME}_task/

## Next Step
Run: /brewcode:plan .claude/tasks/{TIMESTAMP}_{NAME}_task/
