Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.01530 |
| Opus 5 | $0.00010 | $0.00765 |
| Sonnet 5 | $0.00004 | $0.00306 |
| Haiku 4.5 | $0.00002 | $0.00153 |
Grade A, and why
README Writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
README Writer
What this skill does
This skill directs the agent to read a project's structure, package.json (or equivalent manifest), source files, and any existing documentation, then generate a complete, professional README.md. The output adapts its tone and structure to the type of project — a CLI tool, a web app, a library, or a framework — and covers everything a new user or contributor needs to get started.
Use this when you have a new project without documentation, an outdated README, or an open-source project you want to present well.
How to use
Claude Code / Cline
Copy this file to .agents/skills/readme-writer/SKILL.md in your project root.
Then ask:
- "Use the README Writer skill to generate a README for this project."
- "Write a professional README.md for this repo using the README Writer skill."
The agent will explore the project structure on its own. You can also provide a description of what the project does if the code alone isn't self-explanatory.
Cursor
Add the "Prompt / Instructions" section to your .cursorrules file. Then open the relevant files (package.json, main entry point) and ask Cursor to write the README.
Codex
Paste your package.json (or equivalent), the main entry file, and a brief description of the project. Then include the instructions below.
The Prompt / Instructions for the Agent
When asked to write a README, follow these steps:
-
Gather information. Read:
package.json,pyproject.toml,Cargo.toml,go.mod, or equivalent manifest for name, description, version, dependencies, and scripts- The main entry point file to understand the project's purpose
- Any existing
README.md,CHANGELOG.md, ordocs/folder - The directory structure (top level) to understand the project layout
LICENSEfile to identify the license
-
Determine the project type and adapt accordingly:
- Library/Package — focus on API reference, installation, and code examples
- CLI tool — focus on installation, commands, flags, and usage examples
- Web application — focus on features, setup, and deployment
- Framework/boilerplate — focus on getting started, conventions, and architecture
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

README Writer is a skill published in the GitHub repository Notysoty/openagentskills (9 stars, last pushed 26d ago), licensed MIT. It adds 21 tokens to every session and 1,530 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
