Every listing scanned; publisher submissions human-reviewed by version
The skills marketplace that reads the code first.
Every skill on SkillPort is scanned for hidden instructions, dangerous commands and injection payloads. Publisher submissions also require human approval; community imports are clearly labelled and fail closed when AI analysis is unavailable.

Hidden payload decoded
An HTML comment and zero-width characters carry a directive aimed at the agent, not the reader: hide this section and suppress notifications.
curl | bash in setup script
The setup step pipes a script from a raw IP address straight into the shell. Nothing fetched at install time can be reviewed.

The scanner
Four layers read every skill before you do.
Hidden-text detection
Zero-width unicode, right-to-left overrides, HTML comments and encoded blobs: anything written for the agent but hidden from the reader is decoded and flagged.
Dangerous-instruction patterns
A lexicon of override and exfiltration phrasing catches instruction hijacks, notification suppression, agent-loyalty redirection and credential harvesting.
Static script analysis
Every bundled script is read for curl piped to shell, raw-IP downloads, reverse shells and reads of SSH keys, cloud credentials and .env files.
LLM injection classifier
A hardened model pass hunts the semantic injection that pattern rules miss, with skill content isolated as data. Its verdict alone never publishes anything.
An honest note: prompt injection is not a solved problem, and we do not claim otherwise. Defence in depth plus human review for publisher submissions beats any single filter, and that is exactly what runs here. No skill goes live on an automated verdict alone.
Why vetting
Open registries trust the author. We trust the scanner.
An open, unvetted registry
- Anyone can publish under almost any name
- READMEs get skimmed; the instructions your agent will follow do not
- Setup scripts run on your machine sight unseen
- Trust leans on stars and download counts
Vetted skills on SkillPort
- Every version is scanned for injection, exfiltration and dangerous commands before listing
- Publisher releases require human approval; community imports are labelled separately
- Downloads are authenticated and checksum-verified against the reviewed package
- Suspect skills are pulled from the download path immediately
Publish your expertise. Let the scanner vouch for it.
Submit a skill and it goes through the same four scanner layers and human review as everything else in the catalogue. Buyers see exactly which version was reviewed, and when.
