    How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 2 are distinctive, and 2 are very specific to this project.

  1. Very specific:

  2. Very specific:

    If you can see the project's code, offer to make the fix where the headers are set (web server config, framework middleware, hosting config …

    After a fix is deployed, run it again and show the new grade.

  4. Distinctive:

    Only public http/https sites on ports 80/443.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Unchore site check

For "is my site locked properly?", "why is my security grade low?", "add a security badge to the README".

How to use

  1. Run from this skill's folder (Node 22+, no install): node scripts/site-check.mjs example.com (add --json for machine-readable output)
  2. Tell the user the grade, then the failed checks in order of points lost, each with its fix, in the user's language. If you can see the project's code, offer to make the fix where the headers are set (web server config, framework middleware, hosting config such as vercel.json, netlify.toml, _headers, nginx add_header).
  3. After a fix is deployed, run it again and show the new grade.
  4. Offer the badge line from the output for the README. It says what was measured (security headers) — don't describe it as a full security audit.

Rules

  • Only public http/https sites on ports 80/443. Private, local and cloud-metadata addresses are refused on purpose.
  • It sends one ordinary GET to the site — nothing else, and nothing to Unchore.
  • Headers are one layer. For logs, code or a suspicious file, use the unchore-defend skill.
