Example usage:

user: "What's left on this branch before we can ship?" assistant: A survey question across git state, tests, and config. I'll delegate it and ask for a short report so the raw command output stays out of my context. ${AGENT_TOOL_NAME}({ 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." }) The prompt is self-contained: it states the goal, lists what to check, and caps the response length. The agent's report comes back as the tool result; relay the findings to the user. 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. ${AGENT_TOOL_NAME}({ 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?" }) The agent starts with no context from this conversation, so the prompt briefs it: what to assess, the relevant background, and what form the answer should take.
