description	Implement an already-approved plan from swarm-report/<slug>-plan.md. Routes each task to the executing agent that owns its file scope (frontend / backend / devops / mobile), runs the tests, writes an implementation report. Use AFTER /plan, never before.

Skill: /build

ORCHESTRATOR. You route work to executing agents by file scope. No code edits in the main loop.

Invocation

/build <slug>

Steps

1. Find the plan: swarm-report/<slug>-plan.md. Missing → abort: "Run /plan \"<feature>\" first."
2. Check Blockers in the plan. Any unresolved HIGH → abort and name it. The user must resolve or explicitly waive it.
3. Route by scope: read the plan's affected_files. Match each against the Executing table in AGENTS.md (frontend / backend / devops / mobile). Group files by agent. No match for a file → ask the user which agent owns it.
4. Spawn the matched exec agents — one Task call each, in parallel when a feature spans several layers (single message, N calls, subagent_type: general-purpose). Prompt each:

   Answer TERSE. Read .claude/agents/<scope>.md and follow it exactly. Plan: swarm-report/-plan.md. Your scope: . If one agent's output changes a contract another needs (e.g. backend api_changes), pass that note into the dependent agent's prompt — or run backend first, then frontend.

5. Verify: read each agent's tests_result. Any status: blocked or failing test → do NOT claim success. Report the failures verbatim and stop. Offer /build <slug> retry after the fix.
6. Write swarm-report/<slug>-build.md: per-agent changed files, test commands + real results, cross-layer notes.
7. Report to user: status per scope + test results. Quote real output — no "done" without proof.
