Development

Local Development Setup

When developing these plugins, you can install them from local source:

claude plugin marketplace add ./

Updating

After making changes, run /reload-plugins in Claude Code to pick up the changes without restarting.

Force Reinstall (Development)

Claude Code caches plugins by version number. If you modify plugin files without bumping the version in marketplace.json, /reload-plugins will reload from the stale cache and not pick up your changes.

Solution: run ./force-reinstall.sh to bypass the version cache and force a full reinstall from source:

./force-reinstall.sh

Use this when:

• You've modified SKILL.md, scripts, agents, or other plugin files
• /reload-plugins is not reflecting your changes

Plugin Root Resolution

Skills use the ${CLAUDE_SKILL_DIR} environment variable (introduced in Claude Code 2.1.69) to locate their packaged scripts. Claude Code substitutes this variable in SKILL.md content at load time with the skill's installed directory path.

Minimum required version: Claude Code 2.1.69

Skills will halt and display an error if run on an older version.

Testing

Scripts used by skills are tested using Node.js with the native node:test module.

Run tests with this plugin's dev-workflow:run-tests skill ("eat your own dogfood") or:

npm test

See test/CLAUDE.md for testing methodology, patterns, and examples.
