What it does

Write Readme is an agent skill from cdiggins/plato. Write or review a project README.md in plain technical-writer prose — problem it solves and doesn't, honest assessment of tested vs untested, trade-offs, prior art, organization, and usage. Use when the user says "write a README", "improve/review the README", "document this project", or a new project/repo lacks a README.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Technical documentation, Technical writing and Intellectual property. The repository describes itself as: A simple and efficient cross-platform programming language. The licence is MIT.

When your agent uses it

  • The user says write a README
  • Improve/review the README
  • Document this project
  • A new project/repo lacks a README

Example prompts

  • “write a README”
  • “improve/review the README”
  • “document this project”
  • “/write-readme”

What it can do on your machine

Read from SKILL.md and the folder at commit f6e02cf. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Write Readme loads about 1.6k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 857 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

write-readme — project READMEs in technical-writer prose

Every project and repository gets a README.md written for the user of the project, not its author. The measure of success: a reader of any background can decide whether this project is appropriate for them and, if so, how to use it effectively — without reading the code or asking anyone.

Voice and language (non-negotiable)

  • Write as a technical writer, not a marketer and not the proud author.
  • Complete sentences. No fragments, no note-style bullets that assume context.
  • No jargon. Every unfamiliar term is defined at first use or replaced with a plain phrase ("a YAML header that holds the item's state", not "frontmatter"). Expand every acronym once before using it.
  • No marketing language. Ban superlatives ("blazingly fast", "powerful", "simple yet flexible") and unfalsifiable claims. State measurable facts; let the reader judge.
  • Active voice, present tense. Say who does what: "the script rebuilds the index", not "the index is rebuilt".
  • Consistent terminology: pick one name per interface and never alternate synonyms.

Required content

Cover each of these. Order below is the recommended reading order — motivation before mechanics, honesty before installation.

  1. What it is — one or two sentences a stranger understands with zero context. Name the audience ("for developers who…").
  2. What problem it solves — the concrete failure or pain that exists without it. A reader who does not have this problem should realize it here and stop reading, satisfied.
  3. What problem it does NOT solve — explicit non-goals and out-of-scope needs. This prevents misuse and disappointed adopters, and it is the section most READMEs are missing.
  4. Show the thing early — a small, real example (input and output, a short session, or a screenshot for visual tools) before any long prose. Readers evaluate artifacts, not descriptions.
  5. How to use it — prerequisites stated exactly (language versions, OS, accounts), installation commands that have actually been run, and the shortest path to a first success. Include a way to verify the install worked.
  6. Trade-offs — what was deliberately given up and why (e.g. "no dependencies, so the parser is naive and the schema must stay flat"). Every design buys something by paying something; say both sides.
  7. Known and tested vs. untested — separate what is demonstrated (with dates, versions, or test evidence) from what is intended, hoped, or unproven. Use absolute dates ("extracted 2026-07-18"), never "currently" or "as of this writing" — those rot silently.
  8. Similar and related prior work — name the closest existing tools, state honestly how this differs, and keep originality claims narrow. Not inventing the category is normal; pretending to is a credibility hole. Caveat comparisons that may go stale.
  9. How the project is organized — a short map of the directories or files that matter (a table works well: path, purpose), so a reader can navigate without spelunking.
  10. Who it is for / who it is not for (yet) — the reader should find themselves in one of these lists.
  11. License, and where to get help or report problems if applicable.

Additional principles

  • The README is a front door, not a manual. Link to deeper docs rather than inlining design essays, full API references, or change history. Aim for a document readable in five to ten minutes.
  • Every claim must be verifiable against the project today. Before finishing: run the install and usage commands (or trace them against the code), check version requirements against the actual source (e.g. syntax features imply a minimum language version), and confirm paths and filenames exist. A README that lies once is distrusted everywhere.
  • Write for the skeptical evaluator. The most valuable reader is deciding whether to adopt. Honest weaknesses ("built for a single writer; two branches filing concurrently will collide") build more adoption than hidden ones, because evaluators always find out.
  • State maturity plainly. Experimental, personal-use, production, abandoned — say which, and date it. If the project is two days old, say it is two days old.
  • Prefer one concrete number to three adjectives. "About 250 lines, no dependencies" beats "lightweight and minimal".
  • Anti-patterns to remove on sight: badge walls; feature lists with no problem framing; "simply"/"just" before nontrivial steps; install steps that skip prerequisites; screenshots or examples that no longer match the current behavior; TODO sections; empty boilerplate headings ("Contributing: TBD").
  • Maintenance rule: the README changes in the same commit as any behavior it describes. A stale README is worse than a short one.

Procedure

  1. Read the project first: entry points, real commands, actual dependencies and minimum versions, directory layout, tests. Never write from the author's description alone — the code is the source of truth for every factual claim.
  2. Ask (or infer from context) anything material you cannot determine: intended audience, maturity, license. Do not invent these.
  3. Draft in the section order above. Cut any section that would be empty rather than padding it — but treat missing "does not solve", "untested", or "prior art" sections as gaps to research, not sections to skip.
  4. Verify every command, path, version, and filename against the project.
  5. Reread once as the target reader: could someone with no context decide, in five minutes, whether and how to use this? Fix whatever blocks that.

To copy it by hand, put the folder in .cursor/skills/write-readme, .gemini/skills/write-readme, .github/skills/write-readme and .opencode/skills/write-readme in your project.

What does Write Readme need to run?

SKILL.md names no scripts, command-line tools or credentials: Write Readme is instructions for the agent only.

Does Write Readme access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
