Individual skill
harness-similarity
Weighted similarity (ADR-152) between two harness fingerprints (genome + score JSON): an overall score in [0,1] plus per-component breakdown. Use when comparing two harnesses or detecting drift between them. Pure TypeScript; needs no @metaharness package.

Read excerpt
Surfaces the production similarity function from [`scripts/_similarity.mjs`](../../scripts/_similarity.mjs) as a callable skill. Use when an agent needs to:
- decide whether to fork an existing harness vs scaffold a new one
- rank candidate templates against a target repo's genome
- diff two harnesses produced by different teams to find duplicate work
- generate the confidence number that ADR-151 §3.2's Recommender wraps
## Algorithm (from ADR-152 §Decision)
```
overall = 0.60·cosine + 0.25·categorical + 0.15·jaccard
```
- **cosine** — over a 9-dim numerical vector of normalized scorecard + genome dims
