Test development and improvement system that tracks quality patterns and progressively improves the test suite.
Full audit of test suite quality including coverage gaps, brittle patterns, and assertion quality. Use this skill when the user asks to "audit tests", "review test quality", "find test gaps", "are my tests good enough", or any request to assess the overall health and completeness of the project's test suite.
Generate tests for a specified module using project conventions. Use this skill when the user asks to "write tests for", "generate tests", "add test coverage", "test this module", or any request to create new test files following the project's existing patterns, fixtures, and assertion style. Optionally generates an eval suite if the eval-framework plugin is installed.
Extract testing lessons from bug fixes and update the knowledge base. Use this skill when the user asks to "learn from this bug", "extract a testing lesson", "update test knowledge", "what should we test for this", or after completing a bug fix to capture reusable test patterns that prevent similar regressions.
A 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)
claude-md/ # CLAUDE.md templates
hooks/ # Hook recipes
mcp/ # MCP server configs
tools/ # Development & validation tooling
tests/ # Plugin validation gates
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
