5-dimension harness readiness scorecard from `metaharness score <path>`. Returns harnessFit / compileConfidence / taskCoverage / toolSafety / memoryUsefulness + estCostPerRunUsd + scaffoldReady. Pure-read; subprocess invocation; degrades gracefully when MetaHarness is absent (ADR-150 architectural constraint).
One-command drift detection. Composes audit-list + oia-audit + audit-trend into a single primitive — finds the most recent audit in `metaharness-audit` namespace, runs a fresh audit against the current repo, diffs them via ADR-152 §3.1 similarity, and alerts when structural distance crosses `--threshold`. Iter 53 of ADR-150 deep integration.
ADR-152 — weighted similarity between two harness fingerprints (genome + score JSON). Returns overall score in [0,1] plus per-component breakdown (cosine over 9 numerics, categorical agreement over 4 enums, jaccard over agent_topology). Unblocks ADR-151 §3.2 Recommender, §3.3 Drift Detection, §3.5 Plugin Compat. Pure-TS, no `@metaharness/*` dep — preserves ADR-150's four architectural constraints.
Composite Phase-2 audit worker (ADR-150). Bundles harness oia-manifest + threat-model + mcp-scan into one timestamped audit record stored in the `metaharness-audit` memory namespace. Designed for cron-scheduled drift detection.
7-section repo readiness report from `metaharness genome <path>`. Returns repo_type / agent_topology / risk_score / mcp_surface / test_confidence / publish_readiness. Pure-read; degrades gracefully (ADR-150).
Static security scan of a harness's declared MCP surface via `harness mcp-scan <path>`. Reads `.mcp/servers.json` + `.harness/claims.json`. Pure-read, no dispatch. Exits 1 on findings at or above `--fail-on` severity.
Scaffold a custom AI agent harness via `metaharness new <name> --template <id> --host <id>`. Defaults to DRY-RUN (no writes) unless --confirm is passed. Refuses to write to the calling repo root or anywhere inside it. Honors ADR-150 architectural constraint + ruflo's "destructive-action confirmation" pattern.

Surfaces the upstream metaharness score CLI as a ruflo skill. Use when
Claude Code needs to assess whether a repo is ready for harness adoption
before recommending the user run npx ruflo init or harness-mint.
Implementation: scripts/score.mjs.
npx metaharness score <path> --json (single subprocess,
60s hard timeout).{ harnessFit, compileConfidence, taskCoverage, toolSafety, memoryUsefulness, estCostPerRunUsd, recommendedMode, archetype, template, scaffoldReady, hardConstraints }.--alert-on-fit-below N: exit 1 when harnessFit < N.| Dimension | Value |
|---|---|
| harnessFit | 82/100 |
| compileConfidence | 100 |
| taskCoverage | 79 |
| toolSafety | 100 |
| memoryUsefulness | 40 |
| estCostPerRunUsd | $0.048 |
| recommendedMode | CLI + MCP |
| archetype | typescript-sdk-harness |
| template | vertical:coding |
| scaffoldReady | true |
Ruflo passes its own readiness check. memoryUsefulness: 40 is the
weakest dimension — track this as a leading indicator for future memory
work in the AgentDB layer.
node plugins/ruflo-metaharness/scripts/score.mjs --alert-on-fit-below 70 --format json
Exit 1 fails the build. Pair with harness-genome for the full
7-section view.
When metaharness is not installed and npx can't fetch it (offline,
no network, registry unreachable), the script emits:
{
"degraded": true,
"reason": "metaharness-not-available",
"hint": "Install metaharness manually with `npm i -D metaharness` or run `npx metaharness@latest --version` to verify network access."
}
and exits 0. Ruflo continues to function — this is the architectural constraint in action.
