labrat: Skill for Claude Code

.agents/skills/labrat-operator/SKILL.md

labrat-operator is a skill for Claude Code, Codex from ProjectDXAI/labrat. It costs 42 tokens per session (816 once invoked), scanned A, original, MIT.

A set of operating instructions for running a labrat lab, an automated software research workspace that tests and evaluates candidate implementations.

In plain words
What is it for?
It helps diagnose the lab, inspect its status, select the next phase prompt, manage cycles, audit candidates, summarize evaluations and maintain checkpoint notes.
Why use it?
It provides a repeatable way to check the lab, choose the next task, supervise runtime cycles, review candidates and keep coordination notes aligned with the runtime’s records.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is ProjectDXAI/labrat's own configuration. It tells Claude Code and Codex how to work on labrat itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything labrat configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

labrat-operator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

labrat Operator

Use this skill from a labrat lab root, identified by branches.yaml, evaluation.yaml, runtime.yaml, and scripts/operator_helper.py.

Codex can load this skill implicitly when a task matches the description, or explicitly when the user references $labrat-operator. Keep this skill focused on lab operation; repo release mechanics belong in the root AGENTS.md.

Cold Start

  1. Run python scripts/operator_helper.py doctor.
  2. Run python scripts/operator_helper.py status.
  3. Read coordination/workspace_map.md.
  4. Read coordination/prioritized_tasks.md.
  5. Run python scripts/operator_helper.py next-prompt --runner codex --phase auto.

If you are operating from the repo root, use the equivalent labrat ... --lab-dir <path> commands.

If both repo-root and lab-local AGENTS.md files are loaded, use the lab-local AGENTS.md for runtime operation and the root AGENTS.md for repo maintenance.

Operation Contract

  • The runtime is authoritative. Do not hand-score candidates or edit state/*.json[l] directly.
  • Do one complete operator loop before returning unless a stop condition fires.
  • Reap stale leases, summarize runtime state, synthesize recent evaluations, dispatch work, lease runnable jobs, execute scripts/run_experiment.py, complete candidates through scripts/runtime.py, and verify the resulting state.
  • Use scripts/evaluator.py and scripts/runtime.py for scoring and promotion.
  • Write durable conclusions to coordination/prioritized_tasks.md, logs/checkpoints/, logs/audits/, or logs/expansions/.

Codex Modes

  • Use GPT-5.5 in Codex for design, audit, frame break, profile authoring, release work, and review when it is available in the user's Codex host.
  • Use Plan mode before broad workflow, docs, scaffold, or profile changes.
  • Use normal execution for routine doctor, status, next-prompt, dispatch, lease, and complete loops.
  • Use Codex review after changes to runtime behavior, scaffolding, prompt contracts, or release metadata.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
