git-wiki

A self-maintaining knowledge wiki that lives in your own git repo. Your agent ingests sources, writes the pages, keeps cross-references current, and answers from the wiki. On-device hybrid search. No server, no SaaS, no DB — local commits by default, optional GitHub publishing.

bash <(curl -sL https://raw.githubusercontent.com/rarce/git-wiki/main/install.sh)

Features

• Compounds over time — every ingested source and answered query enriches the wiki.
• Your repo is the store — versioned, portable, shareable locally or via GitHub, diffs as a change log. Zero hidden state to corrupt.
• On-device hybrid search — BM25 + vector + LLM rerank via qmd. No external API, no embeddings uploaded anywhere.
• No server, no SaaS — the only runtime is bash, git, qmd, and optionally gh for GitHub sync.
• Agent-Skills standard — works with Claude Code, Cursor, Codex, Copilot, or any Agent-Skills-compatible agent.
• Lint for drift — stale dates, orphans, broken links, index drift, missing cross-references, and contradictions.

How it works

Three layers from the Karpathy LLM-wiki pattern:

1. Raw sources (sources/) — articles, papers, notes. Immutable; the LLM reads but never rewrites them.
2. Wiki pages (pages/, people/, concepts/) — LLM-owned markdown; synthesis accumulates here.
3. Schema (CLAUDE.md + SKILL.md) — conventions and workflows the LLM follows.

Two navigation files:

• index.md — content catalog, grouped by category. Read first on every query.
• log.md — append-only chronological record, grep-friendly (## [YYYY-MM-DD] <op> | <title>).

git-wiki vs classic RAG

	Classic RAG	git-wiki
What's retrieved	raw chunks	curated wiki pages
Quality over time	flat	compounds with each ingest
Storage	vector DB	markdown in git
Contradictions	silently coexist	surfaced by lint
Ownership	vendor-specific DB	a git repo you own
Portability	migrate DB, reindex	git clone / local copy

Who this is for

• You read a lot (papers, articles, docs) and wish your agent remembered it.
• You want your knowledge portable, versioned, and yours — not locked in a vendor DB.
• You already work in an Agent-Skills-compatible editor (Claude Code, Cursor, Codex, Copilot…).
• You prefer plain markdown + git over proprietary formats.

This repo hosts the skill, not a wiki. Installing it gives your agent the git-wiki capability; running scripts/setup.sh creates your personal wiki as a separate repo. The installer creates a private GitHub repo by default, or a local-only repo with WIKI_VIS=local.

Pieces

piece	role
gh	create, clone, and push GitHub-backed wiki repos (optional for local-only)
git	local commits and branching
qmd	on-device BM25 + vector + LLM-rerank search over the wiki
the skill	runs from any Agent-Skills-compatible agent and edits the files

Prerequisites

• gh authenticated (gh auth status) for GitHub-backed installs
• git with user.name and user.email configured
• node + npm (for npx skills add)
• qmd installed and available on PATH
• An Agent-Skills-compatible agent (Claude Code, Cursor, Copilot, …)

Install

One-shot (recommended)

bash <(curl -sL https://raw.githubusercontent.com/rarce/git-wiki/main/install.sh)

The installer will:

1. Check dependencies (git, node, npm, qmd, and authenticated gh unless using local-only mode).
2. Prompt for a wiki repo name, visibility (private, public, or local), and local wiki path.
3. Create the wiki repo: gh repo create --clone for GitHub-backed installs, or git init for WIKI_VIS=local.
4. npx -y skills add rarce/git-wiki — drops the skill into .agents/skills/git-wiki/ inside the wiki repo.
5. Runs the bundled scaffolder (.agents/skills/git-wiki/scripts/setup.sh), which lays out CLAUDE.md, index.md, log.md, pages/, people/, concepts/, sources/, registers the wiki with qmd, commits, and pushes only when an origin remote exists. The scaffolder does not install external packages.

Non-interactive (env vars)

All three prompts can be pre-set:

WIKI_REPO=my-wiki WIKI_VIS=private WIKI_DIR=~/wiki \
  bash <(curl -sL https://raw.githubusercontent.com/rarce/git-wiki/main/install.sh)

For a local-only wiki that is never published to GitHub:

WIKI_REPO=my-wiki WIKI_VIS=local WIKI_DIR=~/wiki \
  bash <(curl -sL https://raw.githubusercontent.com/rarce/git-wiki/main/install.sh)

Inspect-then-run (paranoid option)

curl -sL https://raw.githubusercontent.com/rarce/git-wiki/main/install.sh -o install.sh
less install.sh
bash install.sh

Manual install

If you prefer to run each step yourself — for example, to add the skill to a wiki repo you already have:

# 1. Create (or cd into) the wiki repo
gh repo create my-wiki --private --clone
cd my-wiki

# 2. Install the skill into this repo
npx -y skills add rarce/git-wiki

# 3. Run the bundled scaffolder
.agents/skills/git-wiki/scripts/setup.sh

For manual local-only setup:

mkdir my-wiki
cd my-wiki
git init -b main
npx -y skills add rarce/git-wiki
GIT_WIKI_LOCAL=1 .agents/skills/git-wiki/scripts/setup.sh

The scaffolder expects to be run from inside a git repo; it will not create or clone a repo for you.

Usage

From inside the wiki repo (or with WIKI_DIR set), invoke your agent and use any of:

• Ingest a source: "ingest this article: <url|path>"
• Query: "what do I know about <topic>?"
• Lint: "lint the wiki" — checks for stale dates, orphans, broken links, index drift, and missing cross-references.

The skill takes care of file layout, index/log updates, qmd re-embedding, and local commits. GitHub-backed repos can also push to origin.
