Install

# Install with uv
uv tool install dkb

# Or with pipx
pipx install dkb

Usage

$ dkb add tailwindlabs/tailwindcss.com/src/docs --version-url tailwindlabs/tailwindcss
✓ tailwindcss 4.3.3 → ~/.local/share/dkb/tailwindcss

$ dkb add colinhacks/zod/packages/docs/content
✓ zod 4.6.7 → ~/.local/share/dkb/zod

$ dkb                      # alone: the status

$ dkb update               # parallel, skips what did not move upstream
  - tailwindcss unchanged
  ✓ zod         updated

$ dkb update zdo
Error: not in the catalogue: 'zdo' (did you mean 'zod'?); `dkb status` lists it

$ dkb add n0-computer/iroh-ffi/IrohLib/Docs
Error: path 'IrohLib/Docs' not found; 'IrohLib/' has: .swiftpm/, Sources/, Tests/, .gitignore, README.md

Piped (dkb status | grep zod, an agent's shell), status prints one plain line per repo with a header and the docs location; dkb status --json prints everything. dkb -h lists the files dkb owns and more add examples.

Configuration

Two files, two owners:

The catalogue is the declaration and is meant to be tracked in a dotfiles repo. dkb update reconciles the cache with it: clones anything declared that is missing, re-clones anything whose upstream commit or declared paths/branch changed, re-reads every version and description, prunes clones nobody declares, and regenerates the skill; it exits 1 if any repo failed. A failed fetch keeps the previous clone and version: new content is assembled beside the old and swapped in only when complete. Without a declared branch, a repo follows its remote's default branch, whatever it is called. Metadata comes from gh when it is logged in, else from GitHub's public API (60 requests/hour). A fresh machine is one dkb update away from the same knowledge base. dkb status exits 1 while a declared repo has no clone, so it doubles as a drift check.

// ~/.config/dkb/config.json
{
  "repositories": {
    "next.js": { "url": "https://github.com/vercel/next.js.git", "paths": ["docs"] },
    "tailwindcss.com": { "url": "https://github.com/tailwindlabs/tailwindcss.com.git", "paths": ["src/docs"] }
  }
}

Upgrading from dkb 2: the catalogue used to live in the data dir as one file with the state mixed in. dkb 3 refuses to run while that file exists and prints where each half goes.

Features

• ✨ Auto-naming - No need to specify names, automatically derived from repositories
• 🎯 Path-specific URLs - Add only the docs you need: dkb add owner/repo/path
• 🔗 Multiple URL formats:
  • Full URLs: https://github.com/astral-sh/uv/tree/main/docs
  • Shorthand: tailwindlabs/tailwindcss.com/src/docs
  • Classic: https://github.com/denoland/docs.git
• 🏠 Gitea/Forgejo support - Works with codeberg.org and self-hosted forges: dkb add https://code.haverbeke.berlin/wordgard/website/src/branch/main/site/docs
• 📦 Version tracking - Track versions from a different repository with --version-url
• 🚀 Parallel updates - All repos update concurrently with live progress spinners
• ⚡ Smart skip - Unchanged repos detected via git ls-remote without cloning
• 📂 Sparse checkout - Repos with paths only fetch the files they need
• 🧭 Errors that say what to do - typo suggestions, the real contents of a mistyped path, git's own message instead of its command line
• 🤖 Claude Code skill - Maintains ~/.claude/skills/dkb/SKILL.md; the always-visible description indexes the catalogue so the agent knows what's cached without running anything

Roadmap

• Local repos - dkb add ~/Developer/my-lib symlinking the live checkout into the cache, so first-party libraries in the catalogue point at the working copy instead of a lagging remote clone
