eval-analyze

eval-analyze is a skill for Claude Code from opendatahub-io/agent-eval-harness. It costs 130 tokens per session (4,362 once invoked), scanned A, original, Apache-2.0.

An evaluation-configuration generator for an agent testing system. It creates an eval.yaml file describing how a skill or custom prompt should be tested.

In plain words
What is it for?
It analyzes skills, creates or updates evaluation configurations, and can assess multiple skills to suggest which ones need testing.
Why use it?
It removes the need to manually discover a skill’s files, scripts, and test cases and turn them into test settings.

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

eval-analyze 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 5d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/assess_skills.py, scripts/find_skills.py, scripts/list_builtins.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You generate eval.yaml — the configuration that /eval-run needs. You either:

  1. Analyze a skill (default): Read the skill deeply (including sub-skills), explore test cases, generate config for testing the skill
  2. Custom analysis (--prompt): Execute a custom analysis prompt that defines what to evaluate and how

The core principle: observe, don't assume. Every field name, file pattern, and directory path in the generated eval.yaml must come from reading actual files. If you can't point to a specific file or field you observed, don't put it in the config.

Step 0: Parse Arguments and Discover Layout

Argument Required Default Description
--skill <name> no auto-detect Which skill to analyze
--config <path> no auto-discover Output path for the config
--prompt <path> no none Custom analysis prompt (for non-skill evals)
--update no false Fill in missing sections only, preserve user edits
--assess no false Assess all skills and recommend which ones need evals

If $ARGUMENTS contains --assess: skip the rest of Step 0 and Step 1. Go directly to Batch Assessment (between Step 0 and Step 1). Do not run state.py init, do not discover configs, do not look for a single skill.

Otherwise, proceed with the normal flow:

mkdir -p tmp
python3 ${CLAUDE_SKILL_DIR}/scripts/agent_eval/state.py init tmp/analyze-config.yaml \
  skill=<skill> prompt=<prompt> config=<config> update=<true/false>

Config Location Discovery

If --config provided, use that path. Otherwise run python3 ${CLAUDE_SKILL_DIR}/../../scripts/discover.py and decide:

  • No configs: Create eval.yaml at project root
  • One root config and --skill targets a different eval than the existing one: offer to reorganize into eval/ layout. If the user accepts, run python3 ${CLAUDE_SKILL_DIR}/scripts/reorganize.py --eval-name <name> (add --project-root <path> if not the cwd). If declined, ask where to put the new config.
  • Nested/flat layout already exists: place the new config at eval/<skill-name>/eval.yaml (nested) or alongside existing flat configs

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.
