llms.txt Generator

Generate llms.txt files — LLM-friendly markdown indexes of project documentation following the llmstxt.org specification.

Scope

This skill generates llms.txt and llms-full.txt files. Does NOT handle: hosting, deployment, SEO, robots.txt, sitemaps.

When to Use

• Project needs LLM-friendly documentation index
• Publishing docs site and want AI discoverability
• Creating context files for AI assistants
• User asks for "llms.txt", "LLM documentation", "AI-friendly docs"

Arguments

• No args: Scan current project's ./docs directory
• path: Scan specific directory or file
• --full: Also generate llms-full.txt (expanded with inline content)
• --output path: Custom output location (default: project root)
• --url base: Base URL prefix for links (e.g., https://example.com/docs)

Workflow

1. Gather Sources

From docs directory (default):

# Scout docs directory for markdown files

Use /ck:scout to find all .md, .mdx files in target directory.

From URL: Use WebFetch to retrieve existing documentation structure.

2. Analyze & Categorize

For each discovered file:

• Extract H1 title (first # heading)
• Extract first paragraph as description
• Categorize by section (API, Guides, Reference, etc.)
• Determine priority: core docs vs optional/supplementary

3. Generate llms.txt

Run generation script:

$HOME/.opencode/skills/.venv/bin/python3 scripts/generate-llms-txt.py \
  --source <path> \
  --output <output-path> \
  --base-url <url> \
  [--full]

Or generate manually following spec in references/llms-txt-specification.md.

4. Structure Output

Follow llmstxt.org specification strictly:

# Project Name

> Brief project description with essential context.

## Section Name

- [Doc Title](url): Brief description of content
- [Another Doc](url): What this covers

## Optional

- [Less Important Doc](url): Supplementary information

5. Validate

• H1 heading present (required)
• Blockquote summary present (recommended)
• All links valid markdown format: [title](url)
• Optional section at end for skippable content
• Concise descriptions, no jargon

Format Rules (llmstxt.org Spec)

Element	Rule
H1	Required. Project/site name
Blockquote	Recommended. Brief essential context
Sections	H2-delimited groups of related links
Links	[Title](url): Optional description
## Optional	Special section — skippable for short context windows
Language	Concise, clear, no unexplained jargon

See references/llms-txt-specification.md for full spec details.

Output Files

File	Content
llms.txt	Curated index with links and descriptions
llms-full.txt	Expanded version with inline doc content (use --full)
