    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.

The file

We split this skill into the rules it gives an agent

3 rules. 0 are common, 3 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 167 edited versions we read keep these.

  • 3

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Treat every MCP tool call as attacker-controlled structured input even after authentication.

    line 8
  2. Distinctive:

    Never log bearer tokens, pairing codes, tool args, file contents, terminal output or tool results.

    line 13
  3. Distinctive:

    Prefer argv execution; shell mode is explicit and documented as privileged.

    line 18

“Common” is measured: kept by at least 6 in 10 of the 167 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Security review

Treat every MCP tool call as attacker-controlled structured input even after authentication.

Mandatory invariants:

  • Prove device ownership before online-state lookup or dispatch.
  • Never log bearer tokens, pairing codes, tool args, file contents, terminal output or tool results.
  • Store device/pairing secrets only as hashes; compare secrets in constant time.
  • Require TLS outside loopback; validate configured URLs on startup.
  • Canonicalize symlinks/ancestors before allowed-root checks; refuse direct symlink overwrite.
  • Bound frame/body/header sizes, list counts, reads/writes, process buffers, process count and in-flight calls.
  • Prefer argv execution; shell mode is explicit and documented as privileged.
  • Cloud components never execute arbitrary local commands.
  • Production access tokens require subject, expiration, scope and exact resource audience.
  • Database audit is metadata-only by default.

For dependency changes, prefer standard library or widely reviewed upstream packages, pin versions, run govulncheck, and document why the dependency is needed.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
