quicknotes

claude-marketplace

A collection of Claude Code plugins — installable via the litianningdatadog-marketplace plugin marketplace. Each plugin delivers a skill that extends Claude's capabilities with a specialized, repeatable workflow.

Each plugin has a .claude-plugin/plugin.json manifest and a skills/<name>/SKILL.md that becomes Claude's operating instructions once the skill activates. Supporting scripts live under <plugin>/scripts/. This README is the entry point for humans browsing or installing the repo.

Plugins

Skill	What it does
efficiency-audit	Analyzes recent Claude Code transcripts to surface recurring friction — corrections, re-explained context, tool-call failures, failing hooks — grouped by recurrence count and dominant project. LLM synthesis drafts ranked CLAUDE.md rules with token-savings estimates; idempotent marker blocks prevent duplicate accumulation across re-runs.
hook-doctor	Inspects and repairs installed plugin hook configurations (hooks.json). Detects unquoted ${CLAUDE_PLUGIN_ROOT} commands that fail in agent-mode, reports them, and applies safe idempotent fixes with explicit opt-in.
quicknotes	Low-friction quick-note capture and management. Centralized markdown notes (~/.quicknotes) with date/project/dir metadata, tags, fuzzy search, references, and time/location reminders; completing a note deletes it. Capture via the qn CLI (instant), /qn, or natural language.

Installing plugins

This repo is a Claude Code plugin marketplace. Add it once, then install skills à la carte:

# Add the marketplace (once per machine)
/plugin marketplace add litianningdatadog/claude-marketplace

# Install skills
/plugin install efficiency-audit@litianningdatadog-marketplace
/plugin install hook-doctor@litianningdatadog-marketplace
/plugin install quicknotes@litianningdatadog-marketplace

Plugins auto-update when you run /plugin marketplace update. Each skill activates automatically when your request matches the triggers in its SKILL.md description.

Development

No build system or third-party dependencies — skills are Markdown plus scripts. Scripts that ship tests use the Python standard-library unittest, run from the script's directory. Per-skill setup, CLI usage, and test commands live in each skill's README.

Contributing a new skill

1. Create a top-level directory named in kebab-case (matches the skill's name).
2. Add a .claude-plugin/plugin.json with name and description.
3. Add skills/<name>/SKILL.md as the agent procedure. Front-load trigger phrases in the frontmatter description — it's the only text read when deciding whether to activate. Reference supporting scripts via ${PLUGIN_ROOT}/scripts/... (resolved dynamically at runtime).
4. Put supporting code under <skill>/scripts/ (stays at the plugin root).
5. Add the plugin entry to .claude-plugin/marketplace.json and the skill to the table above.

See CLAUDE.md for the conventions Claude follows when working in this repo.
