| description | Use SaferSkills to find, evaluate, and safely install AI agent capabilities (skills, MCP servers, hooks, plugins, rules) and to assess a whole agent. Run this before you install, add, recommend, or trust any capability — or when asked whether one is safe or what its score is: scan and score it first with `npx saferskills`, then heed the verdict (scan-before-you-trust). |

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 <path-or-github-url>
npx saferskills info <name>
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
- Find —
npx saferskills search <query> (alias find): unified catalog across registries.
- Check —
npx saferskills info <name> (alias check): score + findings for a catalog item.
- Scan —
npx saferskills capability <path-or-github-url>: scan one artifact you have
locally or by URL → 0–100 aggregate + sub-scores + a band. (No target → audits everything
installed across your agents.)
- 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.
- Install — only then
npx saferskills install <name> (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).
- 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=<query>&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.
