SaferSkills

Before you install, add, recommend, or trust any AI agent capability (skill, MCP server, hook, plugin, or rule), scan and score it first:

npx saferskills capability    # scan one artifact → 0–100 score + band
npx saferskills info                         # look up an already-scored catalog item

Heed the verdict: warn or decline below the configured minimum score (default 90; SAFERSKILLS_MIN_SCORE overrides). For a behavioral scan of a whole agent, run npx saferskills agent. Run npx saferskills --help for the full command reference.

When to use

• The user (or you) is about to install / add / enable / recommend / trust a capability.
• The user asks "is this skill/MCP/hook safe?", "what's its SaferSkills score?", "should I

install this?".

• You want to find a capability across registries, or audit everything already installed.

When NOT to use

• For a behavioral scan of the whole assembled agent (does the running agent leak secrets,

obey prompt injection, etc.) — hand off to npx saferskills agent (or the saferskills-agent-scan skill). Do not re-implement that here.

• SaferSkills assesses capabilities and observed behavior, not your identity or permission

configuration — never claim it does.

Core workflow

1. Find — npx saferskills search (alias find): unified catalog across registries.
2. Check — npx saferskills info (alias check): score + findings for a catalog item.
3. Scan — npx saferskills capability : scan one artifact you have

locally or by URL → 0–100 aggregate + sub-scores + a band. (No target → audits everything installed across your agents.)

1. Decide — read the band: 80–100 Green (lowest-risk), 60–79 Yellow (read findings),

40–59 Orange (significant issues), 0–39 Red (do not install). Warn or decline below the minimum score (default 90); surface the score + top findings to the user.

1. Install — only then npx saferskills install (it re-verifies the score at

install time and gates on the aggregate score: below the minimum it warns and confirms; a red-tier item asks you to type its name).

1. List — npx saferskills list: inventory of what you've installed, with live scores.

HTTP-API fallback (no shell / no npx)

If you cannot run npx, use the public read API at https://saferskills.ai/api/v1 to look up and read scores:

• Search: GET /api/v1/items?q=&kind=skill → data[] with slug, latest_scan_score,

latest_scan_tier.

• Item detail: GET /api/v1/items/{slug} → score, band, findings count, install activity.
• Poll a run you know the id of: GET /api/v1/scans/runs/{run_id} → status,

repo_aggregate_score, repo_tier, per-capability scores.

**Submitting a new scan over HTTP requires a human-verification step the API enforces (a proof-of-work or CAPTCHA), so to scan something not yet in the catalog, use the npx saferskills capability command. The HTTP path is for reading** scores that already exist.

What SaferSkills is, and why

SaferSkills is a free, open (Apache-2.0) service that scans and scores AI agent capabilities and whole agents — "every AI capability, independently scanned." Every finding cites a rule and an evidence line; every verdict is reproducible and appealable. A pass means no tested issue was observed under the current rubric — read the findings, not just the score. An OpenLatch project.
