Skills

Opinionated, curated Claude Code skills — vendored from upstream sources (mattpocock-skills, superpowers, etc.) and drifted toward a personal style.

Plugins

• dev — general development tooling
  • manage-claude-md — create, review, and improve CLAUDE.md files
  • install-claude-sidecar — install the Claude sidecar viewer
  • tdd — test-driven development with a red-green-refactor loop
  • systematic-debugging — finding root cause before applying a fix
  • implement-with-review-loop — implement changes under a worktree-isolated implement-then-review loop
  • ponytail — force the laziest solution that actually works — YAGNI, stdlib first, shortest diff
• meta — skills for maintaining this marketplace itself
  • import-skill — vendor a new skill from a GitHub upstream
  • refresh-vendored — reconcile vendored skills against upstream changes
  • merge-skill — shared core that reconciles two skill versions into one (used by the above)
• productivity — process and workflow skills
  • grill-me — launcher that opens a grilling session (thin shim)
  • grilling — stress-test a plan, decision, or idea by relentless one-question-at-a-time interrogation
  • write-a-skill — reference for the craft of writing skills: predictability, context vs cognitive load, information hierarchy, leading words, failure modes
  • teach — turn the working directory into a stateful workspace for learning a topic across sessions
  • capture-decision — end-of-session capture into a decision archive via multi-agent review loop
  • recall-decision — mid-session lookup against a decision archive via a sub-agent digest
• personal — Mehrdad's personal working defaults
  • work-like-mehrdad — engineering defaults for judgment, building, and reviewing; loads at the start of any code-touching session
• in-progress — skills being actively authored or rewritten (under evaluation, not marketplace-listed)
  • wayfinder — plan oversized work as a map of decision tickets on an issue tracker, resolved one at a time
  • domain-modeling — pin down a domain's terms and boundaries; record choices as ADRs
  • research — resolve a factual question a decision waits on via a focused research subagent
  • prototype — make a cheap, rough artifact (outline, stub, UI/logic) to react to
  • weigh-feature-complexity — break a spec or PR into features and visualize the complexity each one adds
• deprecated — skills phased out, kept installable during transitions
  • handoff — compact the current conversation into a handoff doc for the next session

Installation

1. Run claude inside any repo
2. /plugin marketplace add mithredate/skills
3. /plugin install <plugin-name>@skills

Vendoring and maintenance

Most skills here are forks of upstream open-source work. Lifecycle:

• Add a new vendored skill — invoke /import-skill. Interactive: gathers upstream coords, clones, copies files into a target plugin, writes the canonical attribution footer with the fork-commit SHA, and updates marketplace.json and NOTICES.md.
• Refresh existing vendored skills — invoke /refresh-vendored. Surfaces upstream changes since the fork commit, lets you adopt or skip each change, and adjusts the attribution verb if local drift has shifted bands (Adapted from → Inspired by → Originally seeded from).

Attribution

Each vendored SKILL.md carries a one-line footer at the bottom with the source URL (including the fork-commit SHA) and license. The repo-level summary lives in NOTICES.md. Canonical footer format: meta/skills/import-skill/references/footer-format.md.
