Hcs Regression Trap

Category: General  ·  Sub-category: general-misc  ·  Last updated:
Convert an observed agent failure (stale CLI memory, wrong toolchain, deprecated syntax) into a regression trap entry for the HCS eval corpus.

From the source SKILL.md

Use when an agent (yourself, a reviewer, a human) observes a failure class that should be caught by HCS going forward. Trap authorship is the mechanism that converts one-off bugs into permanent eval coverage.
