Agent Evaluation

davila7/claude-code-templates
637 installs30.2k stars
Summary

This is for when you need to actually test agent reliability before production, not just run them through benchmarks once and hope. It covers statistical test evaluation (running tests multiple times to analyze distributions), behavioral contract testing for invariants, and adversarial testing to actively break things. The sharp edges table is the most useful part: it calls out real problems like agents scoring well on benchmarks but failing in production, flaky tests that pass sometimes, and accidental data leakage. The core insight is right: evaluating LLM agents isn't like testing traditional software because the same input produces different outputs. You'll want this if you've ever watched an agent that passed all your tests completely fall apart with real users.

deliver-edge-cases

product-on-purpose/pm-skills

Documents edge cases, error states, boundary conditions, race conditions, and recovery paths for a feature - the systematic catalog of what can go wrong and the failure modes to design for. Use during specification to map the failure surface and ensure comprehensive coverage, or during QA planning to identify boundary and limit scenarios to test. Distinct from deliver-acceptance-criteria, which writes story-level Given/When/Then checks; this skill produces the whole-feature edge-case catalog.
