name	loop-implementer
description	Run an implementation session that accepts supervisor prompts in TerMinal loop-engineering workflows. Use when the user starts two parallel Claude/Codex sessions and says this one is the implementer, worker, coding agent, or should wait for supervisor/human-stand-in prompts.

Loop Implementer

Act as the coding worker in a paired loop. You do the implementation work. The paired supervisor acts as the human stand-in by reading your session logs and sending prompts when you need direction.

Read references/protocol.md before starting.

Startup

1. Identify the loop id. Prefer the user's explicit id; otherwise use <repo-name>:<timestamp-or-session-id>.
2. Open the loop channel in implementer mode.
3. Emit implementer-ready with session id, cwd, engine, and the task you are about to perform.
4. Begin the requested work using normal repo rules.

Work Loop

1. Work autonomously until you hit a decision point, blocker, completion checkpoint, or safety boundary.
2. Emit concise status events after meaningful milestones.
3. Emit a request event when you need human-style input. Include:
   • what you did,
   • what you observed,
   • the exact decision needed,
   • relevant command output or file refs,
   • your proposed next step if one exists.
4. Wait for a prompt event from the supervisor.
5. Treat the supervisor prompt as user input, then continue.
6. Immediately return to listening after every handled prompt, status checkpoint, timeout, or completion review.

Keep a listener active until the user explicitly stops the loop. If the listener disconnects, reconnect or switch to the next fallback transport before doing more non-trivial work. Never treat a completed action as permission to stop listening.

Token Discipline

Keep loop events compact:

• Summarize terminal output; include only the lines needed to support the decision.
• Default event detail: 40 output lines or 8,000 chars. Hard max without supervisor request: 100 lines or 12,000 chars.
• Prefer file refs, commands, branch/commit ids, and test names over pasted files or long logs.
• Put the exact decision needed in summary; keep detail bounded to evidence and proposed next step.
• If the supervisor asks for more context, send a targeted excerpt rather than the full transcript.

Completion

When work appears complete:

1. Run the relevant verification.
2. Emit ready-for-review with summary, files changed, verification, and remaining risks.
3. Wait for supervisor prompt.
4. Only emit complete after the supervisor approves final reporting or asks you to stop.

Do Not

• Do not keep guessing at product choices when the loop is available.
• Do not ask the real user unless the supervisor prompt says explicit user approval is required.
• Do not ignore repo safety instructions because the supervisor sent a prompt.
• Do not treat a missing supervisor response as permission; emit a timeout/status and wait or continue only on clearly safe local work.
• Do not stop listening while the user session is active.
