Installation

kamae-ts ships as a set of coding-agent skill plugins. Install them with either of the following CLIs.

Via gh skill

gh skill is the GitHub CLI’s agent skills extension.

# Install a single skill (interactive prompt for agent/scope)
gh skill install iwasa-kosui/kamae-ts kamae

# Install non-interactively for Claude Code at user scope
gh skill install iwasa-kosui/kamae-ts kamae \
  --agent claude-code --scope user

# Pin to a specific release
gh skill install iwasa-kosui/kamae-ts kamae@v1.0.0

Via skills CLI

skills is Anthropic’s general-purpose skill installer.

npx skills add iwasa-kosui/kamae-ts

This installs every skill the plugin provides at once.

Provided skills

Skill	Triggered when
kamae	Writing server-side TypeScript — domain models, use cases, repositories, state transitions, error handling, boundary validation, PII protection.
kamae-review	Reviewing code. Walks a checklist of severity-tagged review items and cites the canonical principle in kamae. Depends on kamae being installed — install both together.

Verifying the installation

After installing, your coding agent should see kamae (and optionally kamae-review) listed among available skills. Refer to your agent’s documentation for how to confirm — for example, in Claude Code, run /skills and look for kamae-ts:kamae in the list.

Customization

Both skills load applicable rules from the following locations, in priority order:

1. .claude/rules/*.md (project)
2. ~/.claude/rules/*.md (user-global)
3. The plugin’s own rules/defaults/*.md

A rule applies to kamae-ts when its frontmatter declares applies-to: kamae, applies-to: kamae-review, or applies-to: "*". See rules/README.md in the repository for the rule format and examples.

For full skill replacement, use Claude Code’s standard skill path-shadowing — .claude/skills/kamae/SKILL.md overrides the installed plugin’s version.
