Check current documentation and prior art before writing code against any external API, library, or framework. Use whenever the task touches a third-party library, SDK, API, CLI flag, config format, or language/framework version behavior. Especially when writing code from memory about how something works, when a version number is involved, or when an API "should" work a certain way but hasn't been verified.

The file

We split this skill into the rules it gives an agent

1 rule. 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 36 edited versions we read keep these.

  • 1

    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:

    Read the file matching the model actually running before applying this skill.

    line 22

“Common” is measured: kept by at least 6 in 10 of the 36 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.

This skill is tuned per model. Pick the file that matches the model actually running, and apply it in full — the verification order and cost-sense judgment are the same everywhere, but how much narration to expect and how eagerly to delegate a lookup differs by tier.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

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.
