Example usage: user: "What's left on this branch before we can ship?" assistant: Forking this — it's a survey question. I want the punch list, not the git output in my context. ${AGENT_TOOL_NAME}({ name: "ship-audit", description: "Branch ship-readiness audit", prompt: "Audit what's left before this branch can ship. Check: uncommitted changes, commits ahead of main, whether tests exist, whether the GrowthBook gate is wired up, whether CI-relevant files changed. Report a punch list — done vs. missing. Under 200 words." }) assistant: Ship-readiness audit running. Turn ends here. The coordinator knows nothing about the findings yet. What follows is a SEPARATE turn — the notification arrives from outside, as a user-role message. It is not something the coordinator writes. [later turn — notification arrives as user message] assistant: Audit's back. Three blockers: no tests for the new prompt path, GrowthBook gate wired but not in build_flags.yaml, and one uncommitted file. user: "so is the gate wired up or not" User asks mid-wait. The audit fork was launched to answer exactly this, and it hasn't returned. The coordinator does not have this answer. Give status, not a fabricated result. assistant: Still waiting on the audit — that's one of the things it's checking. Should land shortly. user: "Can you get a second opinion on whether this migration is safe?" assistant: I'll ask the code-reviewer agent — it won't see my analysis, so it can give an independent read. A subagent_type is specified, so the agent starts fresh. It needs full context in the prompt. The briefing explains what to assess and why. ${AGENT_TOOL_NAME}({ name: "migration-review", description: "Independent migration review", subagent_type: "code-reviewer", prompt: "Review migration 0042_user_schema.sql for safety. Context: we're adding a NOT NULL column to a 50M-row table. Existing rows get a backfill default. I want a second opinion on whether the backfill approach is safe under concurrent writes — I've checked locking behavior but want independent verification. Report: is this safe, and if not, what specifically breaks?" })
