LLM Documentation (llms.txt)

Many libraries provide LLM-optimized documentation at /llms.txt following the llms.txt standard.

Available Sources

When to Use llms.txt

Use llms.txt when:

• Starting work with a library - Get the architectural overview first
• Context7 lacks recent updates - llms.txt is always current
• You need official API reference links - llms.txt links to authoritative docs
• Understanding library structure - See what sections/features exist

llms.txt vs Context7

Recommended workflow: Start with llms.txt for overview, then use Context7 for specific implementation details.

---

Workflow

1. Fetch llms.txt for Overview

Use Firecrawl to fetch the llms.txt file:

Copyfirecrawl_scrape({ 
  url: "https://effect.website/llms.txt",
  formats: ["markdown"]
})

This returns a structured overview with:

• Project description
• Key documentation sections
• Links to important resources

2. Fetch Full Documentation (if available)

For deeper context, some libraries provide llms-full.txt:

Copyfirecrawl_scrape({ 
  url: "https://effect.website/llms-full.txt",
  formats: ["markdown"]
})

Note: Full versions can be large. Only fetch when you need comprehensive documentation.

3. Follow Up with Context7

After understanding the structure from llms.txt, query specific topics:

Copycontext7_resolve_library_id({ libraryName: "effect typescript" })
→ /effect-ts/effect

context7_get_library_docs({ 
  libraryId: "/effect-ts/effect",
  topic: "schema validation with branded types"
})

Best Practices

1. Check llms.txt first - Before diving into code, understand the library structure
2. Use the registry - Reference llm-docs-registry.yaml for known URLs
3. Prefer llms.txt over scraping random pages - It's curated for LLM consumption
4. Combine sources - llms.txt → Context7 → specific doc pages
5. Cache when appropriate - For repeated work, save llms.txt content locally
