llms.txt Generator

Generate llms.txt and llms-full.txt files that provide LLM-friendly access to wiki documentation, following the llms.txt specification.

When This Skill Activates

• User asks to generate llms.txt or mentions the llms.txt standard
• User wants to make documentation "LLM-friendly" or "LLM-readable"
• User asks for a project summary file for language models
• User mentions llms-full.txt or context-expanded documentation

Source Repository Resolution (MUST DO FIRST)

Before generating, resolve the source repository context:

1. Check for git remote: Run git remote get-url origin
2. Ask the user: "Is this a local-only repository, or do you have a source repository URL?"
   • Remote URL → store as REPO_URL
   • Local → use relative paths only
3. Determine default branch: Run git rev-parse --abbrev-ref HEAD
4. Do NOT proceed until resolved

llms.txt Format (Spec-Compliant)

The file follows the llms.txt specification:

# {Project Name}

> {Dense one-paragraph summary — what it does, who it's for, key technologies}

{Important context paragraphs — constraints, architectural philosophy, non-obvious things}

## {Section Name}

- [{Page Title}]({relative-path-to-md}): {One-sentence description of what the reader will learn}

## Optional

- [{Page Title}]({relative-path-to-md}): {Description — these can be skipped for shorter context}

Key Rules

1. H1 — Project name (exactly one, required)
2. Blockquote — Dense, specific summary (required). Must be unique to THIS project.
3. Context paragraphs — Non-obvious constraints, things LLMs would get wrong without being told
4. H2 sections — Organized by topic, each with a list of [Title](url): Description entries
5. "Optional" H2 — Special meaning: links here can be skipped for shorter context
6. Relative links — All paths relative to wiki directory
7. Dynamic — ALL content derived from actual wiki pages, not templates
8. Section order — Most important first: Onboarding → Architecture → Getting Started → Deep Dive → Optional

Description Quality

llms-full.txt Format

Same structure as llms.txt but with full content inlined:

# {Project Name}

> {Same summary}

{Same context}

## {Section Name}

<doc title="{Page Title}" path="{relative-path}">
{Full markdown content — frontmatter stripped, citations and diagrams preserved}
</doc>

Inlining Rules

• Strip YAML frontmatter (--- blocks) from each page
• Preserve Mermaid diagrams — keep ```mermaid fences intact
• Preserve citations — all [file:line](URL) links stay as-is
• Preserve tables — all markdown tables stay intact
• Preserve <!-- Sources: --> comments — these provide diagram provenance

Prerequisites

This skill works best when wiki pages already exist (via /deep-wiki:generate or /deep-wiki:page). If no wiki exists yet:

1. Suggest running /deep-wiki:generate first
2. OR generate a minimal llms.txt from README + source code scan (without wiki page links)

Output Files

Generate three files:

The root ./llms.txt links into wiki/ (e.g., [Guide](./wiki/onboarding/contributor-guide.md)). The wiki/llms.txt uses wiki-relative paths (e.g., [Guide](./onboarding/contributor-guide.md)).

If a root llms.txt already exists and was NOT generated by deep-wiki, do NOT overwrite it.

Validation Checklist

Before finalizing:

• All linked files in llms.txt actually exist
• All <doc> blocks in llms-full.txt have real content (not empty)
• Blockquote is specific to this project (not generic boilerplate)
• Sections ordered by importance
• No duplicate page entries across sections
• "Optional" section only contains truly optional content
• llms.txt is concise (1-5 KB)
• llms-full.txt contains all wiki pages
