We split this skill into the rules it gives an agent

3 rules. 0 are common, 2 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 18 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

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

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Collect facts from the code: before writing a word:

    line 14
  2. Very specific:

    Mark unknowns: If a fact cannot be found (deployment URL, support channel), leave a clearly marked TODO: or ask.

    line 23
  3. Distinctive:

    When improving an existing README, keep correct content, fix what is wrong or stale, and list the changes you made.

    line 36

“Common” is measured: kept by at least 6 in 10 of the 18 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.

README Writer

Overview

A README answers, in order: what is this, why should I care, how do I run it in five minutes, and where do I go next. Every fact comes from the codebase. Nothing is invented.

Method

  1. Collect facts from the code before writing a word:
    • Manifests: package.json, pyproject.toml, pom.xml, go.mod, Cargo.toml — name, description, scripts, engines/versions.
    • Entry points, CLI flags (--help output if runnable), exported API.
    • Configuration: .env.example, config files, required environment variables.
    • Setup steps hidden in scripts, Dockerfiles, Makefiles and CI workflows.
    • License file, contributing guide, existing docs.
  2. Verify every command you will document exists (script name, binary, flag). Do not document npm run dev unless the script is there.
  3. Pick the audience: users of a library or CLI, operators of a service, or contributors. Lead with what that audience needs.
  4. Write using template.md. Drop sections that have no real content.
  5. Mark unknowns. If a fact cannot be found (deployment URL, support channel), leave a clearly marked TODO: or ask; never guess.

Rules

RuleWhy
First two lines say what it is and who it is forReaders decide in seconds
Quickstart works copy-paste on a clean machinePrerequisites and versions listed first
Show one real usage example with real outputExamples beat feature lists
Configuration table: variable, required, default, descriptionMost setup failures are config
No badges, links, screenshots or features that do not existBroken trust is hard to win back
Keep it short; link to docs/ for depthLong READMEs are skimmed, not read

When improving an existing README, keep correct content, fix what is wrong or stale, and list the changes you made.

Common mistakes

  • Generic filler ("This project is a powerful, scalable solution...").
  • Install steps that skip a required environment variable or service (database, API key).
  • Documenting scripts or flags that were renamed or never existed.
  • Copying the whole API reference into the README.
  • Wrong license name compared with the LICENSE file.

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.
