What it does
Harness Genome is an agent skill from ruvnet/ruflo. 7-section repo readiness report from metaharness genome {path}. Returns repotype / agenttopology / riskscore / mcpsurface / testconfidence / publishreadiness. Pure-read; degrades gracefully (ADR-150).
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Bioinformatics and Architecture decision records. It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
When your agent uses it
- Tasks that involve Bioinformatics
- Tasks that involve Architecture decision records
Example prompts
- “/harness-genome”
Requirements
- Node.js
- Pre-approved tools (allowed-tools): Bash
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Shell out to npx metaharness genome --json (60s hard timeout).
- Parse the shape: `{ repo_type, agent_topology[], risk_score,
- Preserve upstream's readiness verdict as verdict and
- If --alert-on-risk-above N: exit 1 when risk_score > N.
- Output JSON (default) or markdown.
What it can do on your machine
Read from SKILL.md and the folder at commit 6c04654. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Harness Genome loads about 558 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 201 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
- Shell out to
npx metaharness genome <path> --json(60s hard timeout). - Parse the shape:
{ repo_type, agent_topology[], risk_score, mcp_surface, test_confidence, publish_readiness }. - Preserve upstream's readiness verdict as
verdictandverdictExitCode. Upstream exits 1 forneeds-workand 2 forblocked; these are valid reports, so the wrapper returns them successfully. - If
--alert-on-risk-above N: exit 1 whenrisk_score > N. - 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_topologyrecommendations drift away from a deliberate architecture choice. - CI gate:
--alert-on-risk-above 0.5fails the build when the repo's risk profile crosses a threshold.
