ring:generating-llms-txt is a skill for Claude Code, Codex from LerianStudio/ring. It costs 109 tokens per session (1,142 once invoked), scanned A, original, Apache-2.0.

A workflow for creating or checking llms.txt, CLAUDE.md, and AGENTS.md files that explain a repository to AI coding tools.

In plain words
What is it for?
Use it to improve a repository's AI-readable documentation or audit existing agent guidance.
Why use it?
It turns scattered information in readmes, build files, documentation, and APIs into guidance that helps coding agents understand a project.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ring:generating-llms-txt 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 4d 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.

LLMs.txt & AI Documentation Generator

When to use

  • Creating a new llms.txt for a repository
  • Auditing an existing llms.txt for completeness
  • Generating CLAUDE.md or AGENTS.md for AI coding agents
  • Improving AI readability of a repository

Skip when

  • Repository already has a complete, up-to-date llms.txt
  • Task is code implementation with no documentation scope
  • Repository is private/internal with no LLM discoverability need

Complementary: ring:running-dev-cycle, ring:implementing-tasks

Generates llms.txt, CLAUDE.md, and AGENTS.md for repositories.

Step 1: Analyze Repository

1. Read README.md — project name, description, purpose
2. Read CONTRIBUTING.md — build, test, lint instructions (if exists)
3. Read Makefile / package.json / go.mod — build system, language, dependencies
4. Scan /docs/ — available documentation
5. Scan /api/ or OpenAPI specs — API surface
6. Read existing llms.txt / CLAUDE.md / AGENTS.md (if mode=audit)
7. Identify: language, architecture, test framework

Step 2: Generate llms.txt

Follow llmstxt.org specification exactly:

# {Project Name}

> {One-line description: language, what it does, license.}

{Optional: architecture, key concepts, domain terminology needed to work with this project.}

## Docs

- [{Doc title}]({url}): {Brief description}

## API Reference

- [{API name}]({url}): {What this covers}

## Code

- [{Key module}]({path}): {What this module does}

## Optional

- [{Secondary resource}]({url}): {Description}

Rules:

  • One H1 (project name), required
  • Blockquote summary — required, include language and license
  • H2 sections only (no H3+)
  • Links: [title](url): description format
  • File in repo root: /llms.txt
  • Target: fits in ~2K tokens

MUST include: name, architecture overview, key domain concepts, links to README/CONTRIBUTING/API docs/key modules.

MUST NOT include: internal-only docs, CI/CD details, issue tracker, full dependency lists, changelog.

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.
