description: Build features with TDD discipline — test first, implement, verify through quality gates
argument-hint: "<feature to build or plan to execute>"

/build — TDD Build Workflow

Execute implementation with TDD discipline: write tests → implement → verify through 6-gate quality system.

Follow [the shared autonomy policy](../skills/_shared/autonomy-policy.md). Reuse scoped execution authorization from an approved plan without re-approval.

Invocation

/build Execute the approved authentication plan
/build Add the payment integration feature

Workflow

Step 1: Setup

Check for an existing plan and its authorization state:

• Approved plan → execute the authorized scope through verification without step/batch checkpoints.
• Clear, reversible micro task directly requested by the user → proceed with zero approval.
• Meaningful change without an approved plan → create or request a concise `/plan`, then ask for one approval at the plan-to-execution boundary.

Destructive actions, production deployment, secrets, payments, and external communication still require explicit approval for the specific action. Keep all existing security and deploy gates.

Apply **cm-execution** skill to choose execution mode:

• Linear batch execution with non-blocking status updates
• Subagent-per-task dispatch
• Parallel for independent problems

Step 2: Implement with TDD

For each task, apply **cm-tdd** skill: 1. **RED** — Write a failing test 2. **GREEN** — Write minimal code to pass 3. **REFACTOR** — Clean up while tests stay green 4. Commit after each green cycle

After each cycle or batch, report status and continue inside the authorized scope. Pause only for a material scope change, evidence-backed blocker, or explicit-approval action.

Step 3: Quality Gate

Apply **cm-quality-gate** skill:

• Static analysis
• Blind review (re-read without context)
• Anti-sycophancy check
• Security scan
• Test coverage verification
• Ship decision

Step 4: Suggest Next

• "Ready for review? → `/review`"
• "Ready to deploy? → `/deploy`"
