Comet
Comet: agent skill harness for turning ideas into evaluated workflows
Is Comet safe? Promising trust profile, but some evidence still deserves review.
Compare Comet
How does it stack up against its Agent Skills neighbours?
Pick any agent to compare →In detail: Comet scores 64.1/100 (Grade C), ranked #62 of 371 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 5.9/10; 58% of recent commits are signed; no published advisory affects its latest release (@rpamis/comet); last pushed 2026-10-10. Every point is earned from checkable signals — never paid placement. How scoring works →
How Comet could raise its score
Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

- Raise the OSSF Scorecard from 5.9 to 9.0lowest checks: Branch-Protection 0, CII-Best-Practices 0, Fuzzing 0 +6.5 → 70.6 B · #30 of 371

Chain of custody
Scanners check what the code says. This traces who ships Comet and whether that has changed: from the source repository, through how changes are reviewed and released, to the package you install. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities and, for skills, AST02 Supply Chain Compromise.

Source Partly signed

Verify this score yourself
Every build re-issues Comet’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.
What this score doesn’t check
It covers who ships the code, not what the code does. It doesn’t read the skill’s instructions for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you install it, such as Cisco Skill Scanner.

Quick Trust Read
How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade C reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

What license does Comet use?
Are Comet's commits signed?
Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.
AI agent surface
MCP, providers, tool surface
These runtime-trust fields — detected from public repo docs and manifests — contribute a bounded adjustment to this project's HVTrust score alongside supply-chain evidence. The exact values each field can add or subtract are documented in the methodology → Compare this surface across every listed agent in the capability matrix →

Detected changes to Comet's runtime surface and supply-chain posture, from daily public-signal snapshots. A change here means our detectors see something different — a genuinely changed capability, or better evidence of an existing one.
Maintain Comet?
For maintainers
HVTrust scores Comet from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
