xxkeefer-skills

Claude Code skills for idiomatic, agnostic workflows. Organized into domains.

Layout

Path	Holds
skills/	The domain plugins -- one directory per domain (see table below).
hooks/	Claude Code hook holders (e.g. tool-policy) -- installable guardrails.
scripts/	Supporting tooling skills depend on (e.g. obsidian/ -- journal Templater scripts).
statusline/	The self-contained Claude Code status line script, installed by /setup-statusline.
output-styles/	Claude Code output styles (e.g. Terse.md).
.claude-plugin/	Marketplace registry (marketplace.json).

Setup

Install as a local marketplace

Add to ~/.claude/settings.json:

{
  "extraKnownMarketplaces": {
    "xxkeefer-skills": {
      "source": {
        "source": "directory",
        "path": "/path/to/this/repo"
      }
    }
  },
  "enabledPlugins": {
    "primitives@xxkeefer-skills": true,
    "developer@xxkeefer-skills": true,
    "journal@xxkeefer-skills": true,
    "projects@xxkeefer-skills": true,
    "meta@xxkeefer-skills": true,
    "omen@xxkeefer-skills": true,
    "scribe@xxkeefer-skills": true,
    "nix-manager@xxkeefer-skills": true,
    "utility@xxkeefer-skills": true,
    "experimental@xxkeefer-skills": true,
    "deprecated@xxkeefer-skills": true
  }
}

primitives is required by all other domains. Enable whichever domains you need.

Publishing a new version

1. Bump the version in the relevant domain's plugin.json (e.g. 1.0.0 -> 1.0.1)
2. Commit and push to main
3. Restart Claude Code on each consuming machine -- it detects the new HEAD SHA and re-caches

Attribution

Several skills were inspired by or adapted directly from Matt Pocock's skills repo:

• grill-it -- taken from Matt's repo
• spike-it -- inspired by Matt's approach to investigation workflows
• tdd -- inspired by Matt's TDD skill, particularly the tracer bullet pattern and anti-horizontal-slice philosophy

Thanks Matt for sharing these publicly.
