Harness Genome

Companion to harness-score. Where score is a 5-dimension numeric scorecard, genome is a 7-section categorical/numeric report covering repo type, agent topology recommendations, risk score (0-1), MCP surface area, test confidence (0-1), and publish readiness (0-1).

Algorithm

Implementation: scripts/genome.mjs.

1. Shell out to npx metaharness genome <path> --json (60s hard timeout).
2. Parse the shape: { repo_type, agent_topology[], risk_score, mcp_surface, test_confidence, publish_readiness }.
3. Preserve upstream's readiness verdict as verdict and verdictExitCode. Upstream exits 1 for needs-work and 2 for blocked; these are valid reports, so the wrapper returns them successfully.
4. If --alert-on-risk-above N: exit 1 when risk_score > N.
5. Output JSON (default) or markdown.

Phase-0 baseline (ruflo, measured 2026-06-16)

{
  "repo_type": "node_mcp_ci",
  "agent_topology": ["maintainer", "tester", "security", "release"],
  "risk_score": 0.27,
  "mcp_surface": "remote",
  "test_confidence": 0.8,
  "publish_readiness": 0.9
}

Ruflo's risk_score: 0.27 is low (good). publish_readiness: 0.9 is high. The mcp_surface: "remote" reflects that ruflo's MCP servers are hosted, not bundled.

When to use

• Pre-mint review: "before scaffolding a custom harness from this repo, should we?" — genome answers it categorically.
• Drift detection: capture genome snapshots over time, diff via cost-diff-style tooling to spot when agent_topology recommendations drift away from a deliberate architecture choice.
• CI gate: --alert-on-risk-above 0.5 fails the build when the repo's risk profile crosses a threshold.

Pairs with

• harness-score — numeric readiness
• harness-mcp-scan — static MCP security findings
• harness-threat-model — enterprise-review-grade threat model
