Instruct architect agents to leverage subagents for parallel work — page analysis, codebase verification, dependency mapping, and pattern discovery — instead of doing everything sequentially.

Write one file per phase to \`.cw/output/phases/{id}.md\`:
|
|
- Frontmatter: \`title\`, \`dependencies\` (list of phase IDs this depends on)
|
|
- Body: what gets built, specific enough for a detail agent to break into tasks without clarifying questions

<phase_design>
|
|
- Single concern, independently deliverable, testable
|
|
- Foundation phases first; minimize cross-phase dependencies
|
|
- 2-5 tasks each. Action-oriented names (what gets built, not how)
|
|
- Tests are part of every phase, not a separate phase
|
|
|
|
<examples>
|
|
<example label="bad">
|
|
Phase 1: Database → Phase 2: API → Phase 3: Frontend → Phase 4: Tests
|
|
</example>
|
|
<example label="good">
|
|
Phase 1: Database + schema tests → Phase 2: API + endpoint tests → Phase 3: Frontend + component tests
|
|
</example>

<dependencies>
|
|
Maximize parallelism. If your plan is fully serial, reconsider.
|
|
|
|
<examples>
|
|
<example label="good">
|
|
\`\`\`
|
|
Wave 1 (parallel): "Database schema", "API skeleton"
|
|
Wave 2 (parallel): "User endpoints" (depends: API skeleton, DB schema), "Auth middleware" (depends: API skeleton)
|
|
Wave 3: "Integration tests" (depends: User endpoints, Auth middleware)
|
|
\`\`\`
|
|
</example>
|
|
<example label="bad">
|
|
\`\`\`
|
|
Phase 1 → Phase 2 → Phase 3 → Phase 4 (fully serial, no parallelism)
|
|
\`\`\`
|
|
</example>
|
|
</examples>
|
|
</dependencies>
|
|
|
|
<file_ownership>
|
|
Parallel phases MUST NOT modify the same files.
|
|
|
|
<examples>
|
|
<example label="bad">
|
|
Phase A "Add user model" and Phase B "Add product model" both modify \`schema.ts\` and \`index.ts\`
|
|
</example>
|
|
<example label="good">
|
|
Phase A creates \`user-schema.ts\`, Phase B creates \`product-schema.ts\`, Phase C "Wire models into index" depends on both
|
|
</example>
|
|
</examples>
|
|
</file_ownership>
|
|
|
|
<specificity>
|
|
Each phase must pass: **"Could a detail agent break this into tasks without clarifying questions?"**
|
|
|
|
<examples>
|
|
<example label="bad">
|
|
"Set up the backend" — what backend? What framework? What endpoints?
|
|
</example>
|
|
<example label="good">
|
|
"Create Express API server with health check endpoint at /api/health, CORS configured for localhost:3000, error handling middleware returning JSON errors"
|
|
</example>

</examples>

<subagent_usage>
|
|
Use subagents to parallelize your analysis — don't do everything sequentially:
|
|
- **Domain decomposition**: Spawn separate subagents to investigate different aspects of the initiative (e.g., one for database/schema concerns, one for API surface, one for frontend components) and synthesize their findings into your phase plan.
|
|
- **Dependency mapping**: Spawn a subagent to map existing code dependencies and file ownership while you analyze initiative requirements, so you can make informed decisions about phase boundaries and parallelism.
|
|
- **Pattern discovery**: When the initiative touches multiple subsystems, spawn subagents to search for existing patterns in each subsystem simultaneously rather than exploring them one at a time.
|
|
|
|
Don't spawn subagents for trivial initiatives with obvious structure — use judgment.
|
|
</subagent_usage>
|
|
|
|
<existing_context>
|
|
- Account for existing phases/tasks — don't plan work already covered
|
|
- Always generate new phase IDs — never reuse existing ones
|
|
