# loading-addressable-markdown

Pulls exactly one Markdown section out of a filesystem tree by an address like file.md#h2-slug. Handy when a task points at a spec section instead of a whole file.

## What it does

The skill parses `file.md#h2-slug` or `file.md#h2-slug/h3-slug` and returns the full heading span, child sections included. Slugs are lowercased, emphasis and code markers are stripped from the heading, and every other non-alphanumeric run collapses to `-`. Headings inside fenced code blocks are skipped, so examples in triple backticks will not confuse the parse.

It runs the bundled `scripts/resolve-markdown.mjs`. Relative paths resolve from `--root`, and without it from the current directory. Duplicate or missing paths fail loudly rather than silently returning something. Quote the address in your shell, or the `#` starts a comment.

\`rig context get` is the wrong tool for an arbitrary disk path — that command resolves context-library refs. Hand-slicing headings with `sed` or line numbers is out too, since the resolver owns span and fence behavior.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill loading-addressable-markdown -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill loading-addressable-markdown -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/loading-addressable-markdown/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill loading-addressable-markdown -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/loading-addressable-markdown/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mvschwarz/openrig loading-addressable-markdown
```

2. **Manually: put the files in place**
- File: `.github/skills/loading-addressable-markdown/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill loading-addressable-markdown -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mvschwarz/openrig --path packages/daemon/assets/plugins/openrig-core/skills/loading-addressable-markdown
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill loading-addressable-markdown -a opencode
```

### 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/mvschwarz/openrig/tree/HEAD/packages/daemon/assets/plugins/openrig-core/skills/loading-addressable-markdown/SKILL.md

## When to use it
- pull a single SPEC.md section by heading slug
- read an H3 nested in an H2 without opening the whole file
- point an agent task at one spec section
- catch a duplicated or missing address before it spreads
- parse headings without tripping over fenced code examples

## Example prompts
- load the section `slices/09-source-cleanup/SPEC.md#proposal`
- read `docs/SPEC.md#api/errors` and show me what's there
- resolve `SPEC.md#proposal` from the mission root

# Loading Addressable Markdown

## Overview

Load exactly one addressed Markdown section from any filesystem tree. The resolver mirrors OpenRig's shipped H2/H3 grammar without requiring the file to live in the context library.

## Use

Run the bundled script. Relative file references resolve from `--root`; without it they resolve from the current directory.

```bash
node ~/.agents/skills/loading-addressable-markdown/scripts/resolve-markdown.mjs \
  --root /path/to/mission \
  'slices/09-source-cleanup/SPEC.md#proposal'
```

The accepted forms are:

- `file.md` — whole file
- `file.md#h2-slug` — full H2 span, including child sections
- `file.md#h2-slug/h3-slug` — full H3 span

Slugs are lowercase; Markdown emphasis/code markers are removed; each other non-alphanumeric run becomes `-`. Duplicate or missing paths fail loudly. Headings inside fenced code blocks are ignored.

## Common mistakes

- Do not use `rig context get` for an arbitrary filesystem path; that command resolves context-library refs.
- Do not hand-slice headings with `sed` or line numbers; the bundled resolver owns span and fence behavior.
- Quote addresses in shell commands.

The third-party file has ended. Everything between the 9591c57e19825b57 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
