Review evaluation history, distinguish system, data, suite, and evaluator changes, and apply an operating response.

  • Eval monitoring
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Trend questions

What it does

Monitor Evals is an agent skill from ai-analyst-lab/ai-analyst. Review evaluation history, distinguish system, data, suite, and evaluator changes, and apply an operating response. Use for regressions, eval monitoring, release gates, or trend questions.

Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering LLM evaluation. The repository describes itself as: AI Product Analyst — Claude Code-powered data analysis toolkit. The licence is MIT.

When your agent uses it

  • Eval monitoring
  • Trend questions

Example prompts

  • “/monitor-evals”

What it can do on your machine

Read from SKILL.md and the folder at commit 52c0744. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Monitor Evals loads about 306 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 132 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~306

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Monitor evaluation history

Read versioned run manifests with helpers.evals.monitoring.load_history. Use classify_changes before comparing scores.

Separate:

  • system behavior changes;
  • data changes;
  • task-mix or suite-version changes;
  • evaluator changes; and
  • operational failures such as blocked tools or expired connections.

Compare only compatible runs. Show per-case and slice movement, not only the aggregate. Run frozen sentinel examples for model graders so evaluator drift does not look like system drift.

Apply the named operating rule:

  • continue when the intended change improved the target slice without a blocking regression;
  • investigate when the cause is unclear or several inputs changed;
  • rollback when a blocking regression follows a controlled system change; or
  • escalate when the evaluator, data, or authorization boundary may be invalid.

Record the owner and next action. Monitoring is an operating practice, not a dashboard someone passively observes.
