FirePass Trio

Autonomous end-to-end agent powered by Kimi K2.6 Turbo. Chains researcher → worker → reviewer in a single MCP call. If the reviewer finds issues and marks them NEEDS-FIXES, the trio loops back: the worker re-runs with reviewer feedback appended to context, then the reviewer re-runs. The loop is bounded by max_review_rounds.

When to use

• End-to-end feature implementation with built-in audit
• Bug fixes that should be planned before coded
• Any change you'd otherwise call all three single-role tools for

When NOT to use

• Pure research (use firepass-researcher)
• Pure implementation with no plan needed (use firepass-worker)
• Pure review of an existing diff (use firepass-reviewer)

Preference

Use INSTEAD OF chaining the three single-role tools manually.

How to use

Call mcp__firepass__firepass_trio with:

• prompt: Clear description of the coding task
• cwd: Important — set to the project root so the agent can find files
• context: Optional pre-loaded file contents, error messages, or specs
• max_iterations: Tool-call rounds per sub-agent (default 60, capped at 200)
• max_review_rounds: Fix loop rounds between worker and reviewer (default 2, capped at 5)

Response shape

<firepass_trio status="..." rounds="N">
  <research>...</research>
  <rounds>
    <round n="1">
      <implementation>...</implementation>
      <review>...</review>
    </round>
    ...
  </rounds>
</firepass_trio>

Status values

• approved: Review passed with no blocking issues, or all issues were fixed within the review rounds
• needs_fixes: Reviewer marked NEEDS-FIXES but max review rounds were exhausted
• research_failed: The researcher step did not complete successfully
• implementation_failed: The worker step did not complete successfully
• review_failed: The reviewer step did not complete successfully

Security

Researcher and reviewer are read-only; worker has full access including bash. All I/O is sandboxed to the provided cwd. See the per-role tool lists in skills/firepass-researcher/SKILL.md, skills/firepass-worker/SKILL.md, and skills/firepass-reviewer/SKILL.md.
