beaker-usage

beaker-usage is a skill for Claude Code, Codex from rilixai/beaker-skill. It costs 95 tokens per session (3,890 once invoked), scanned A, original, MIT.

An operational skill for using an already-configured Beaker integration to run and monitor agent optimization over a repository or other editable resource. Beaker is the connected service used for those optimization runs.

In plain words
What is it for?
Use it to choose a GitHub branch or dataset, launch a run, compare models when supported, inspect run status, and retrieve results.
Why use it?
It guides setup checks, launch preparation, environment validation, status monitoring, and result inspection without changing the project itself.

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

beaker-usage scanned grade A with 1 finding 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 372 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Beaker usage

Operate the repository's connected Beaker integration through the beaker CLI. Keep this workflow operational: do not edit the integration, application, tests, datasets, CI/CD automation, or Beaker config merely to launch or manage a run.

Version check

This skill (0.6.6) is written for beaker-sdk 0.6.6; skill and SDK share one version number and release together. Run beaker --version first. If the CLI is older than 0.6.6 or does not recognize --version, upgrade beaker-sdk through the project's development-dependency workflow. If it is newer than 0.6.6, run npx skills update beaker-usage and npx skills update beaker-setup, then reload the skill before continuing.

Read cli-reference.md when constructing a launch, interpreting status exit codes, pulling results, or handling a CLI error.

During setup validation and launch preparation:

  • Run beaker onboarding status at the start of the flow and after a completed onboarding step, not after read-only probes, then follow its returned action.
  • Relay only newly discovered actions in blocked_on_developer verbatim to the developer without attempting developer-owned work, tracking what was already reported in this session. Batch the currently known actions, ask the developer to begin them immediately, and continue with the returned next.action so their work overlaps with yours. Do not perform integration_pushed while dataset_available or required_env_configured is incomplete; wait once no earlier agent work remains.
  • An unknown step has not been checked yet and never means the developer must act. Stop and wait only when next itself is developer-owned.
  • Complete dataset_available and required_env_configured before integration_pushed, the final blocking agent-owned step. Commit and push the completed integration once, without asking the developer to confirm unless they told you not to take autonomous actions, to a beaker/<YYYYMMDD-HHMM>-<agent-name> branch in the selected agent repository before a hosted optimization run. The agent normally completes dataset selection and experiment_launched too, but the developer may also complete them through the platform UI.
  • Tracing is optional: if it applies, make a best effort to include it in that push, but never let it block the push; never commit secret files.

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.
