API developmentA pair of Claude Code skills for building with CodeIgniter 4. Designed to give Claude a solid, accurate understanding of the CI4 framework
Overview
A trio of Claude Code skills for building with CodeIgniter 4. Designed to give Claude a solid, accurate understanding of the CI4 framework — including Shield authentication. - — Core CI4 framework: MVC conventions, routing, controllers, models, query builder, views, migrations, filters, Spark CLI. - — Building robust REST APIs with CI4: response envelopes, versioning, token auth, validation, rate limiting, CORS, and webhooks. - — Shield authentication & authorization: session auth, access tokens, HMAC, JWT, groups, permissions, email activation, 2FA, magic links. - — Covers advanced CI4 techniques for working outside app/: runtime addNamespace(), namespace-isolated migrations/seeds/commands, Registrars, module auto-discovery, service overrides, runtime config mutation, event bootstrap, and dynamic route inclusion. Each skill has a lean SKILL.

Claude Code Skills: CodeIgniter 4
A trio of Claude Code skills for building with CodeIgniter 4. Designed to give Claude a solid, accurate understanding of the CI4 framework — including Shield authentication.
ci4— Core CI4 framework: MVC conventions, routing, controllers, models, query builder, views, migrations, filters, Spark CLI.ci4-api— Building robust REST APIs with CI4: response envelopes, versioning, token auth, validation, rate limiting, CORS, and webhooks.ci4-shield— Shield authentication & authorization: session auth, access tokens, HMAC, JWT, groups, permissions, email activation, 2FA, magic links.ci4-advanced— Covers advanced CI4 techniques for working outside app/: runtime addNamespace(), namespace-isolated migrations/seeds/commands, Registrars, module auto-discovery, service overrides, runtime config mutation, event bootstrap, and dynamic route inclusion.
Each skill has a lean SKILL.md (~200-350 lines) that loads automatically, plus a references/ directory with comprehensive deep-dive docs that are pulled on demand — keeping context usage efficient.
Installation
Clone this repo directly into your Claude Code skills directory:
git clone https://github.com/enlivenapp/Codeigniter4-App-and-API-Skills-for-Claude-Code.git ~/.claude/skills/codeigniter4
Or if you already have other skills and want to add just these:
cd ~/.claude/skills
git clone https://github.com/enlivenapp/Codeigniter4-App-and-API-Skills-for-Claude-Code.git
cp -r Codeigniter4-App-and-API-Skills-for-Claude-Code/ci4 .
cp -r Codeigniter4-App-and-API-Skills-for-Claude-Code/ci4-api .
cp -r Codeigniter4-App-and-API-Skills-for-Claude-Code/ci4-shield .
cp -r Codeigniter4-App-and-API-Skills-for-Claude-Code/ci4-advanced .
Restart Claude Code. The skills are now available. Claude will automatically activate the relevant skill when it detects CI4-related work or loading via /ci4-{name}.
