## What it does

This skill implements a repository wiki following Andrej Karpathy's architecture. Content lives in three layers: raw files in `raw/`, agent-edited markdown documents, and `SCHEMA.md` defining conventions. You choose between two initial setups: a project record for engineering tasks or a research vault for study. The agent handles editing.

Every working session starts by reading `SCHEMA.md` and `index.md`. Ingestion computes sha256 checksums on incoming source files to detect drift. Pages require at least two `[[wikilinks]]`, while factual clashes get marked with `contested: true`. Work is saved via checkpoints. Without Python 3 available, running `tools/lint.py` fails and prevents proper validation. The wiki can deploy to GitHub Pages through Quartz on branch pushes.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add robertguss/claude-code-toolkit --skill project-wiki -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add robertguss/claude-code-toolkit --skill project-wiki -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add robertguss/claude-code-toolkit --skill project-wiki -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install robertguss/claude-code-toolkit project-wiki
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add robertguss/claude-code-toolkit --skill project-wiki -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/robertguss/claude-code-toolkit --path skills/project-wiki
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add robertguss/claude-code-toolkit --skill project-wiki -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/robertguss/claude-code-toolkit/tree/HEAD/skills/project-wiki/SKILL.md

## When to use it
- Track project decisions, sessions, and roadmap progress directly in markdown
- Archive external reference documents in `raw/` with immutable sha256 checksums
- Organize topic research into interconnected pages using bidirectional `[[wikilinks]]`
- Validate wiki links, orphan pages, and frontmatter constraints with a dedicated linter

## Example prompts
- Ingest the meeting summary from `raw/notes/kickoff.md`, link relevant entity pages, and record changes in `log.md`
- Run a session checkpoint: update the active plan status, refresh the synthesis note, and execute `tools/lint.py`
- Scan `index.md` for contested topics and summarize all contradictory claims marked in the wiki

# Project wiki

A wiki is a persistent, compounding record: interlinked markdown pages the agent
writes and maintains and the human reads. Knowledge is compiled once and kept
current, so every page already carries its cross-references, its contradictions,
and its place in the whole. The pattern is Karpathy's
([`references/karpathy-llm-wiki.md`](references/karpathy-llm-wiki.md)); this
skill is its shape for a repo.

Three layers, all inside the repo:

- **Raw sources** (`raw/`): immutable. Read, never edited. Corrections go on
  wiki pages.
- **The wiki**: the pages. Written by the agent only. In a project run by the
  `lead` skill, the lead writes them and the worker never does.
- **The schema** (`SCHEMA.md`): the page types, frontmatter, tag taxonomy, and
  conventions. The agent and the human co-evolve it; a convention changes there
  first, then on the pages.

Two presets, chosen at init: **project record** (plans, sessions, decisions, a
roadmap board, a standing synthesis, maps) for a repo being built, and
**research vault** (sources, entities, concepts, comparisons, filed queries) for
a topic being studied. Both share the operations below.

## Start of session

Read, in order: `SCHEMA.md` whole, `index.md`, the last 20 entries of `log.md`
(`grep "^## \[" log.md | tail -20` finds them). In a project record, also the
synthesis page and the roadmap board. Only then touch a page.

No `SCHEMA.md` in the repo means the wiki does not exist yet: follow
[`references/init.md`](references/init.md).

## Operations

### Ingest

A source arrives (a URL, a file, a pasted transcript, a worker's report).

1. Save it under `raw/<kind>/` with frontmatter (`source_url`, `ingested`, and
   `sha256` of the body), named by what it is and when.
2. Find what already exists: search `index.md` and the pages for every entity,
   concept, or step the source names. This is the difference between a wiki and
   a pile of duplicates.
3. Write or update pages by the schema's thresholds: a page when a thing appears
   in two sources or is central to one, an update when it is already covered,
   nothing for a passing mention. Every page carries frontmatter from the
   schema, two or more outbound `[[wikilinks]]`, and a `## Related` list. New
   information that contradicts a page keeps both claims with dates, marks
   `contested: true` and `contradictions:` on both, and names the pair for the
   human.
4. Update `index.md` for new pages and append one `log.md` entry naming every
   file touched.
```
