harness-gepa

Surfaces the GEPA (genetic-evolution prompt-adaptation) library exports from @metaharness/darwin/gepa. Unlike the other skills in this plugin there is no CLI binary behind this — the script dynamic-imports the library (local resolution first, versioned cache install as fallback) and calls the subprocess-safe subset.

When to use

• Adopting an evolved policy: --op render shows the actual system prompt a genome compiles to — read THAT, not the raw JSON, before wiring a genome into a harness.
• Auditing a promotion: --op genome loads + validates the shipped cand-6 genome (first holdout-confirmed cheap-tier promotion; provenance ships in the package) or any genome file you point at.
• CI gate on genome edits: --op validate --alert-on-invalid exits 1 on structural errors.
• Debugging a bad run: --op analyze --transcript run.json classifies failure modes (GEPA's failure-class taxonomy) from a transcript array.
