Install

Add this marketplace, then install the plugin:

# From a local clone
/plugin marketplace add /Users/levanhoang/works/henry-plugins
/plugin install henry-tools@henry-plugins

Or, once pushed to GitHub:

/plugin marketplace add <owner>/henry-plugins
/plugin install henry-tools@henry-plugins

Local development

Load the plugin directly without installing:

claude --plugin-dir /Users/levanhoang/works/henry-plugins/henry-tools

After editing skill files, run /reload-plugins to pick up changes.

Adding a new skill

1. Create henry-tools/skills/<skill-name>/SKILL.md.
2. Add YAML frontmatter — at minimum name and description. The description is what Claude reads to decide when to auto-invoke, so make it specific. Add disable-model-invocation: true for user-only commands with side effects.
3. (Optional) Bundle supporting files alongside SKILL.md (e.g. reference.md, scripts/).
4. Run /reload-plugins, then invoke as /henry-tools:<skill-name>.

No manifest edits are needed to add a skill — the plugin auto-discovers everything under skills/. Bump version in henry-tools/.claude-plugin/plugin.json when you ship a meaningful change.
