What it does
LLMs Txt is an agent skill from thatrebeccarae/claude-marketing. Generate and maintain llms.txt files for AI discoverability. Scans repos to create curated content maps that help AI answer engines surface your project accurately. Implements the llms.txt specification from Answer.AI.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `EXAMPLES.md` and `REFERENCE.md`).
It sits in Marketing & SEO, covering AI search optimization. The repository describes itself as: A full marketing department for Claude Code. Skill packs for Klaviyo, Shopify, GA4, Looker Studio, paid media, and more. Audit, optimize, and report using natural language. The licence is MIT.

Example prompts

Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit a8a63ec. 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
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
llmstxt.org
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
LLMs Txt loads about 1.6k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 795 words of instructions outside code blocks.
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.

Generate and maintain llms.txt files that help AI answer engines surface your project accurately.
Install
git clone https://github.com/thatrebeccarae/claude-marketing.git && cp -r claude-marketing/skills/llms-txt ~/.claude/skills/When to Use
- Launching a new open-source project or documentation site
- Major documentation restructure or content overhaul
- Improving your project's visibility in AI search (ChatGPT, Perplexity, Google AI Overviews)
- Onboarding a project to AI-friendly discoverability standards
- Periodic refresh after significant repo changes
What Is llms.txt
llms.txt is a plain-text markdown file placed in a project's root that gives LLMs a curated map of the project's most important content. Think of it as robots.txt for AI comprehension — instead of telling crawlers where they can go, it tells them what matters and how the project is organized.
The specification was proposed by Answer.AI and is documented at llmstxt.org. Adoption is growing across developer tools, documentation sites, and open-source projects. Projects with an llms.txt are easier for AI to understand, cite, and recommend accurately.
Usage
/llms-txt generate [repo-path]
Scan a repository and generate a new llms.txt file. If no path is provided, uses the current working directory.
/llms-txt audit [repo-path]
Check an existing llms.txt for completeness, broken links, stale descriptions, and missing high-priority content. Produces a report with specific recommendations.
/llms-txt update [repo-path]
Refresh an existing llms.txt based on current repo state. Preserves manually curated descriptions while adding new content and removing references to deleted files.
Procedure
Step 1: Scan Repo Structure
Identify all documentation-relevant files in the repository:
- README.md (root and significant subdirectories)
docs/directory and its contents- API documentation (OpenAPI specs, API reference pages)
- Tutorials, guides, and getting-started content
- CHANGELOG.md, CONTRIBUTING.md, FAQ.md
- Architecture and design decision docs
- Configuration and deployment guides
- Example directories with their own READMEs
Step 2: Prioritize Content
Rank discovered content by importance to an LLM trying to understand the project:
| Priority | Content Type | Why It Matters |
|---|---|---|
| P0 | README, Getting Started, API Reference | Entry points — what the project is and how to use it |
| P1 | Tutorials, Guides, Architecture docs | Deeper understanding — how it works and common workflows |
| P2 | CHANGELOG, CONTRIBUTING, FAQ, Config docs | Supporting context — history, community, troubleshooting |
Step 3: Extract Metadata
For each content page, extract or write:
- Title: Clear, descriptive page title
- URL or path: Where to find the content (full URL for hosted docs, relative path for repo files)
- Description: One-line action-oriented summary of what the page covers
Step 4: Generate llms.txt
Assemble the file following the specification format:
- Title line:
# Project Name - Description block: 2-3 sentence summary of what the project does, who it is for, and its primary use case
- Sections: Group content logically (e.g., "Getting Started", "API", "Guides", "Community")
- Content items: Each item is a markdown link with a colon-separated description
See REFERENCE.md for the exact format specification.
Step 5: Optionally Generate llms-full.txt
For projects that benefit from it, generate an expanded version that inlines the actual content of key pages. This is useful for smaller projects where the full documentation fits in a single context window.
Show full SKILL.md (309 more words)Show less
Step 6: User Review
Present the generated llms.txt for review. Flag any decisions made during curation:
- Content that was excluded and why
- Descriptions that were inferred vs extracted from existing metadata
- Sections where additional documentation would improve AI discoverability
Step 7: Write to Repo Root
Save llms.txt (and optionally llms-full.txt) to the repository root.
For projects with hosted documentation sites, also note the recommended placement for the hosted version (site root, e.g., https://docs.example.com/llms.txt).
Hosted Docs and GitHub Pages
If the project has a documentation site (GitHub Pages, ReadTheDocs, Docusaurus, etc.):
- Generate llms.txt with full URLs pointing to the hosted docs, not repo file paths
- Place the file where it will be served at
https://yourdomain.com/llms.txt - For GitHub Pages: add llms.txt to the docs source directory so it deploys automatically
- Consider adding llms.txt to your sitemap or linking it from robots.txt
Key Principles
- Curate, don't dump. An llms.txt that lists every file in the repo is worse than useless. Select the 10-30 most important pages that give an LLM the clearest picture of the project.
- Prioritize entry points. The first few items should answer: what is this, who is it for, and how do I start?
- Keep descriptions action-oriented. "How to configure authentication for SSO providers" beats "Authentication configuration page."
- Match the reader's mental model. Organize sections the way a newcomer would learn the project, not the way the repo is structured.
- Maintain freshness. Stale llms.txt with broken links or outdated descriptions erodes trust. Run
/llms-txt auditafter major documentation changes.
Integration with Other Skills
- aeo-geo-optimizer — llms.txt complements broader AI search optimization; use both for maximum AI discoverability
- technical-seo-audit — Ensure AI crawlers can access your docs before generating llms.txt
- github-readme — A strong README is the foundation of a good llms.txt; optimize it first
For the full specification format, priority ranking criteria, and placement guidance, see REFERENCE.md.
