Individual skill
harness-gepa
Load, validate or render a GEPA genome, or classify failure modes in a run transcript, via @metaharness/darwin/gepa. Use when inspecting or auditing a genome; use harness-evolve for sandbox-scored evolution. Degrades gracefully without darwin.

Read excerpt
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.
