What it does

When installed, the agent gains a structured playbook for setting up long-running or autonomous agent workflows. It helps decide which files the agent may edit, which must stay locked (such as evaluation rubrics and merge rules), where progress is logged so work can resume, and when a person must approve actions like merging or deploying. It is a design guide for the surrounding system rather than a tool that runs code itself.

Great for

  • Engineers building autonomous research or experimentation loops that run without frequent prompts
  • Teams creating background agents that prepare pull requests for human review
  • People designing evaluation setups that stop an agent from scoring its own work

Skip it if

  • Simple one-off chats or short coding tasks, where the extra control structure adds overhead without benefit
  • Projects that only need general quality checks or regression tests; the file says those belong to a different skill (evaluation)
  • Unsupervised production deployment without human approval, which the skill itself warns against

Try asking

  • “Help me design an overnight agent loop that optimizes a prompt against a locked evaluation script with git rollback.”
  • “Which files should be locked, editable, append-only, or human-controlled in my PR-producing agent?”
  • “Create a durable results log format and keep/discard rules for my autonomous experiment runner.”
  • “Review my agent setup for ways it could game its benchmark or weaken its rubric.”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • State your objective in one sentence first, then ask the skill to map the locked and editable surfaces.
  • Keep the evaluator outside the editable area and review any change to rubrics or merge policy yourself.
  • Ask for the durable log structure before starting a long loop so progress survives context loss.
