Skill Autobench

Q: What is a Claude Code skill and how does the Skill Autobench skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Skill Autobench is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Content category.

Author an eval for an existing skill from its REAL usage history, not its spec. Mine invocations from the brain's conversation archive (conversations/) and per-harness session transcripts — a user correction after an invocation is the gold signal — then synthesize an eval_contract plus 4-8 replayable cases with honesty labels (SPEC-DERIVED vs HISTORY-IMPLIED) and stage the result at skills/<name>/eval/autobench-<date>.md as PENDING-HUMAN-APPROVAL. Never rewrites SKILL.md. Ships two guard companions: panel integrity (multi-model judging must prove each provider actually responded) and the fail-improve taxonomy (logged LLM-fallback cases convert to deterministic code over time).

From the source SKILL.md

The self-improving loop has three legs: an eval, a variant generator (SkillOpt), and a replay + judge harness (gbrain eval cross-modal). The generator and the judge ship with gbrain. The persistently missing leg is the eval author — someone has to WRITE the eval, and a spec-derived benchmark only tests what the skill promised, not what users actually asked for or what actually went wrong. This skill writes the eval from reality instead of imagination.
