Implement with subagents

Orchestrate waves of workers over the issue-tracker frontier. This skill extends the Matt Pocock /implement contract with parallel subagents — it does not patch or vendor that skill.

Preflight

Read CONTEXT.md for leading-word definitions and forbidden synonyms (frontier, wave, worker, orchestrator, miolo, claim, dirty-tree integrate, degraded review, resume handshake, host adapter).

1. Working directory is a git repo on the branch that should receive integrated commits.
2. docs/agents/issue-tracker.md and docs/agents/triage-labels.md exist (run /setup-matt-pocock-skills if not).
3. Installed /implement, /tdd, and /code-review resolve on the host. If any is missing, stop and tell the user to install Matt Pocock's skills (e.g. via /setup-matt-pocock-skills). Do not paste a private fork of those skills into the worker prompt.
4. Optional argument: a feature slug or tracker filter. Without it, discover all ready-for-agent tickets the configured tracker exposes for this repo.
5. If this session is a resume, run the resume handshake in references/orchestrator-flow.md before anything else.
