Rules for code that calls the operating system directly. This skill covers file descriptors, file management, durable writes, processes, signals, threads, and interprocess communication. It also covers the toolchain that assembles, links, loads, and runs a program. Use this skill when you open, read, write, copy, move, delete, lock, or scan files. Use it when you start a process, handle a signal, or share memory. Use it when you debug a fault that appears only under load or only sometimes. This skill is not about software architecture. For architecture, use the system-design skill. The content comes from Advanced Programming in the UNIX Environment (Stevens and Rago) and Systems Programming (Donovan).

The file

Show its rules and text

We split this skill into the rules it gives an agent

30 rules. About 0 are common, 9 are distinctive, and 21 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈9

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 21

    Very specific

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

No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.

≈ “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.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

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.
