npx claudepluginhub ats-kinoshita-iso/agent-workshopA plugin library and development framework for Claude Code. This repo serves two purposes:
/plugin install.# Add the marketplace
/plugin marketplace add ats-kinoshita-iso/agent-workshop
# Browse and install plugins
/plugin install planning@agent-workshop
Browse cookbook/ and copy what you need into your project:
cookbook/claude-md/ — CLAUDE.md templates by project typecookbook/hooks/ — Reusable hook recipes for .claude/settings.jsoncookbook/mcp/ — MCP server configurations for common integrations.claude-plugin/ # Marketplace definition (marketplace.json)
plugins/ # Stable, packaged Claude Code plugins
cookbook/ # Golden baseline configs (copy into your projects)

1. Develop in .claude/ → Iterate locally with Claude Code
2. Validate with test suite → uv run pytest
3. Package as plugin → Create plugin.json + SKILL.md in plugins/
4. Auto-register in marketplace → marketplace_gen.py updates marketplace.json
5. Users install from here → /plugin marketplace add ats-kinoshita-iso/agent-workshop

Keeps CLAUDE.md files in sync with the actual codebase by detecting meaningful changes and proposing targeted updates.
Evaluation framework skills for designing scoring rubrics, running structured evaluations on LLM outputs, and comparing candidate outputs to recommend a winner.
Skills for persistent memory across Claude Code sessions: initialize a memory file, recall relevant context for the current task, and persist session learnings.
Observability skills for designing logging and tracing strategies, instrumenting existing code with structured log points, and analyzing trace logs to diagnose production issues.
Structured plan lifecycle management with automatic tracking, gate validation, and archival of implementation plans.
Produces phased implementation plans with explicit gates and validating tests at each checkpoint.
Analyzes and rewrites prompts for Claude Code, applying structured prompt engineering patterns to produce clearer, more effective instructions.
Test development and improvement system that tracks quality patterns and progressively improves the test suite.
Automated workspace hygiene checks that detect build artifacts, stale temp files, orphaned docs, and project-level clutter.
