Agent Evaluation Design
A skill for designing reproducible AI agent evaluations with representative datasets, rubrics, graders, regression gates, and a release decision memo.

What it does
Turns "the agent feels better" into evidence a release owner can act on.
- Defines the unit under test and separates model quality from tool, retrieval, policy, and infrastructure failures
- Builds representative cases plus boundary, long-tail, malformed-input, tool-failure, and adversarial cases with an isolated holdout set
- Picks the least subjective reliable grader: deterministic checks, rubric-bound model graders, or blinded human review
- Freezes prompts, model versions, seeds, retries, and timeouts so baseline and candidate run under identical conditions
- Produces a failure taxonomy, uncertainty estimates, a release gate (critical-case minimum + non-regression + operational limits), and a decision memo
- Uses
scripts/aggregate_results.pyto validate score bounds, missing labels, and pass-rate denominators
Who it's for
- Engineers shipping LLM agents or copilots who need defensible go/no-go evidence
- Teams comparing prompts, models, tools, memory, or orchestration patterns
- QA and platform owners converting production incidents into regression fixtures
Examples
- "Compare v1 and v2 of a support agent": define resolution correctness, citation fidelity, policy compliance, escalation judgment, latency, cost; blind the version labels; run three times; return ship / hold / limited rollout
- "Did this prompt change regress anything?": compute baseline deltas on the holdout set and slice results by task, language, and tool
- "Turn 20 production failures into fixtures": strip private data and wire the cases into the release gate

Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the agent-engineering/agent-evaluation folder from the GitHub repo seb1n/awesome-ai-agent-skills into my ~/.claude/skills/agent-evaluation/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/seb1n/awesome-ai-agent-skills.git && mkdir -p ~/.claude/skills && cp -r awesome-ai-agent-skills/agent-engineering/agent-evaluation ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal.
- Clone the repo:
git clone https://github.com/seb1n/awesome-ai-agent-skills.git - Create the skills folder:
mkdir -p ~/.claude/skills - Copy this skill:
cp -r awesome-ai-agent-skills/agent-engineering/agent-evaluation ~/.claude/skills/ - Confirm the bundled
references/andscripts/folders came along:ls ~/.claude/skills/agent-evaluation - If you plan to run the aggregation script, check Python:
python3 --version - Restart Claude Code and ask something like "design an evaluation plan for my agent" to trigger the skill.
