| description | Measure ExpertPack EK (Esoteric Knowledge) ratio and run automated quality evals. Use when: (1) Measuring what percentage of a pack's content frontier LLMs cannot produce on their own, (2) Running automated eval sets against a pack-powered agent with LLM-as-judge scoring. Requires OpenRouter API key (auto-resolved from OpenClaw auth or OPENROUTER_API_KEY env var). Companion to the main expertpack skill.

ExpertPack Eval
Measure and evaluate ExpertPack quality. Companion to the core expertpack skill.
Note: This skill makes external API calls to OpenRouter for blind probing and LLM-as-judge scoring. Requires an API key.
1. Measure EK Ratio
Blind-probe frontier models to measure what percentage of a pack's propositions they cannot answer without the pack loaded:
python3 {skill_dir}/scripts/eval-ek.py <pack-path> [--models model1,model2] [--sample N] [--output FILE]
- Default models: GPT-4.1-mini, Claude Sonnet 4.6, Gemini 2.0 Flash (via OpenRouter)
- API key: Auto-resolves from OpenClaw auth profiles or
OPENROUTER_API_KEY env var
- Judge model: Claude Sonnet (GPT-4.1-mini is unreliable as judge — defaults to "partial")
- Output: YAML with per-proposition scores and aggregate ratio
Interpretation:
| EK Ratio | Meaning |
|---|
| 0.80+ | Exceptional — almost entirely esoteric |
| 0.60–0.79 | Strong — majority esoteric |
| 0.40–0.59 | Mixed — significant GK padding |
| 0.20–0.39 | Weak — most content already in weights |
| < 0.20 | Minimal value-add |
Add measured ratio to manifest.yaml:
ek_ratio:
value: 0.72
measured: "2026-03-12"
models: ["gpt-4.1-mini", "claude-sonnet-4-6", "gemini-2.0-flash"]
propositions_tested: 142
2. Run Quality Eval
Automated eval against a pack-powered agent endpoint:
python3 {skill_dir}/scripts/run-eval.py \
--questions <eval-set.yaml> \
--endpoint <ws://host:port/path> \
--output <results.yaml> \
--label "baseline"
- Build eval set: 30+ questions (basic, intermediate, advanced, out-of-scope)
- Fix one dimension at a time: structure → agent training → model
- Re-run after each change to verify improvement
