## What it does

The skill produces structured documentation index files per the llms.txt specification. It structures the output with a single project title, a concise summary blockquote, architectural context paragraphs, and categorized links arranged by topic priority from onboarding to optional sections.

It generates three distinct files: root `./llms.txt`, `wiki/llms.txt` for VitePress navigation, and `wiki/llms-full.txt`. For the inlined export, it strips YAML frontmatter from each markdown page while keeping Mermaid diagram fences, tables, citations, and source comments intact inside `<doc>` tags.

Before writing any files, the skill queries Git for the remote URL and default branch, stopping if unresolved. If an existing root `llms.txt` was not created by deep-wiki, the tool refuses to overwrite it. It operates best when wiki markdown pages already exist via `/deep-wiki:generate` or `/deep-wiki:page`.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill wiki-llms-txt -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/wiki-llms-txt/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/wiki-llms-txt/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/wiki-llms-txt/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/wiki-llms-txt/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills wiki-llms-txt
```

2. **Manually: put the files in place**
- File: `.github/skills/wiki-llms-txt/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/deep-wiki/skills/wiki-llms-txt
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/wiki-llms-txt/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/deep-wiki/skills/wiki-llms-txt/SKILL.md

## When to use it
- generate standard llms.txt files for project documentation
- combine multiple wiki markdown files into llms-full.txt
- export documentation while preserving Mermaid diagrams and tables
- prepare VitePress wiki links for language model discovery

## Example prompts
- Generate llms.txt and llms-full.txt from our wiki docs
- Create an llms.txt file following the llmstxt.org spec
- Bundle the documentation into llms-full.txt with inlined pages

# llms.txt Generator

Generate `llms.txt` and `llms-full.txt` files that provide LLM-friendly access to wiki documentation, following the [llms.txt specification](https://llmstxt.org/).

## 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](https://llmstxt.org/):

```markdown
# {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

| ❌ Bad | ✅ Good |
|--------|---------|
| "Architecture overview" | "System architecture showing how Orleans grains communicate via message passing with at-least-once delivery" |
| "Getting started guide" | "Prerequisites, local dev setup with Docker Compose, and first API call walkthrough" |
| "The API reference" | "REST endpoints with auth requirements, rate limits, and request/response schemas" |

## llms-full.txt Format

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

```markdown
# {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>
```
