# wiki-context-pack

Extracts a token-capped, citation-ready slice of an Obsidian vault for downstream agents. Helpful when an assistant needs targeted context without parsing whole vaults.

## What it does

The skill operates in read-only mode. It never writes to vault files like `log.md`, `index.md`, or `.manifest.json`. Given a topic, it packages relevant excerpts up to a token budget, which defaults to 8000. Passing the `--recent` flag switches the search from a topic to newly updated vault notes.

Under the hood, the skill executes the `obsidian-wiki context-pack` CLI command or calls `python3 -m obsidian_wiki.cli` from a cloned repository. It resolves `$OBSIDIAN_VAULT_PATH` to an absolute path before running. If `$OBSIDIAN_VAULT_PATH/AGENTS.md` exists, the assistant reads it for owner instructions but omits it from the output.

Without the `obsidian-wiki` package or its repository clone, the skill stops immediately and asks you to run `pip install obsidian-wiki` instead of reading files manually.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-context-pack -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-context-pack -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-context-pack -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Ar9av/obsidian-wiki wiki-context-pack
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-context-pack -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Ar9av/obsidian-wiki --path .skills/wiki-context-pack
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-context-pack -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/Ar9av/obsidian-wiki/tree/HEAD/.skills/wiki-context-pack/SKILL.md

## When to use it
- Extract an Obsidian context slice capped by a strict token budget
- Pull recent vault updates for an agent using the `--recent` flag
- Export vault metadata as pure JSON without prose wrappers
- Restrict context extraction to public notes using `--public-only`

## Example prompts
- Create an Obsidian context slice for deployment architecture with an 8000 token budget
- Run /wiki-context-pack with --recent and output pure JSON for downstream processing
- Extract public vault notes on caching strategies without modifying vault indexes

# Wiki Context Pack

This is a read-only skill. It must not modify the vault, including `log.md`,
`index.md`, `hot.md`, or `.manifest.json`.

## Before You Start

1. Resolve config using the Config Resolution Protocol in
   `llm-wiki/SKILL.md`: inline `@name`, then walk up from CWD for `.env`,
   then the global config.
2. If `$OBSIDIAN_VAULT_PATH/AGENTS.md` exists, read it as trusted owner
   conventions. Do not include that file as a knowledge excerpt.
3. Canonicalize the configured vault to a physical absolute path before
   invocation:

   ```bash
   OBSIDIAN_VAULT_PATH="$(cd "$OBSIDIAN_VAULT_PATH" && pwd -P)"
   ```

   If this fails, report that the configured vault path is invalid.
4. Parse:
   - topic, required unless `--recent`;
   - `--budget N`, default `8000`;
   - `--recent`;
   - `--public-only`;
   - `--metadata-only`;
   - `--json`.

## Execute

Build the requested arguments, then prefer the installed executable:

```bash
obsidian-wiki context-pack --vault "$OBSIDIAN_VAULT_PATH" "<topic>" --budget 8000
```

For recent activity:

```bash
obsidian-wiki context-pack --vault "$OBSIDIAN_VAULT_PATH" --recent --budget 8000
```

Append the requested flags exactly. If `obsidian-wiki` is unavailable but
`$OBSIDIAN_WIKI_REPO/obsidian_wiki/cli.py` exists, run the same arguments from
that configured clone:

```bash
python3 -m obsidian_wiki.cli context-pack --vault "$OBSIDIAN_VAULT_PATH" "<topic>" --budget 8000
```

Use the executable-or-clone fallback explicitly:

```bash
if command -v obsidian-wiki >/dev/null 2>&1; then
  obsidian-wiki context-pack --vault "$OBSIDIAN_VAULT_PATH" "<topic>" --budget 8000
elif [ -n "${OBSIDIAN_WIKI_REPO:-}" ] && [ -f "$OBSIDIAN_WIKI_REPO/obsidian_wiki/cli.py" ]; then
  (
    cd "$OBSIDIAN_WIKI_REPO"
    python3 -m obsidian_wiki.cli context-pack --vault "$OBSIDIAN_VAULT_PATH" "<topic>" --budget 8000
  )
else
  # Tell the user to run: pip install obsidian-wiki
  # or rerun setup from a valid clone.
fi
```

For `--recent`, substitute `--recent` for `"<topic>"` and keep the default
`--budget 8000`. If neither invocation route exists, give the user the
actionable guidance `pip install obsidian-wiki` or `rerun setup from a valid
clone`; do not silently fall back to manually loading the whole vault.

## Return

Make any working update about the selected vault and topic or recent mode
before execution. Return CLI stdout unchanged as the final payload in every mode
