GPTaku Plugins – a plugin marketplace for Claude Code

What it is – A curated set of 19 open‑source plugins that extend Anthropic’s Claude Code IDE. Each plugin solves a concrete “wall” you hit while using the AI‑powered coding environment: bypassing blocked web pages, extracting design tokens, getting a code review from a stronger model, generating full product specs, and many more workflow helpers.

How you get it – Inside a running Claude Code session run the two‑step marketplace command:

/plugin marketplace add https://github.com/fivetaku/gptaku_plugins.git   # add the repo
/plugin install <plugin‑name>@gptaku-plugins   # e.g. insane-search
/reload-plugins                                 # apply without restarting

The flagship plugin is insane-search, which you’re encouraged to install first because most other plugins only need a live Claude Code session.

Key plugins (the “insane‑*” series)

Plugin	What it does	Typical prompt
insane-search	Tries a cascade of public readers, syndication gateways, TLS impersonation and a headless browser to fetch pages blocked by WAFs, 403s, CAPTCHAs, or login walls – no API keys required.	“Find what people are saying about Claude Code on Reddit and summarize the top threads.”
insane-design	Pulls the full CSS from any URL and distills it into design tokens (colors, fonts, spacing, shadows) plus a design.md spec and an interactive HTML report.	“Extract the design system from https://stripe.com.”
insane-review	Sends the current repository (via repomix) to a logged‑in ChatGPT Pro/Plus web session and returns a line‑by‑line code review – again without needing an OpenAI API key.	“Have GPT‑5.5 Pro review the auth flow in src/auth.”
insane-research	A 7‑phase, multi‑agent pipeline that scopes a research question, spawns specialist agents, cross‑checks sources, and produces a citation‑rich Markdown report.	“Research the best vector database for RAG in 2026, with citations.”

Other useful plugins

• show-me-the-prd – Turn a one‑sentence idea into a full product‑requirements document, data model, phase plan and spec.
• goaljaby – Convert a PRD into a verified /goal execution contract for Claude Code’s goal‑oriented workflow.
• pumasi – Connect Claude Code to the external Codex CLI so the AI can act as a project manager while a parallel dev team runs on the host machine.
• kkirikkiri – Build a team of AI agents from a single sentence description.
• nopal – Google Workspace orchestration (Gmail, Calendar, Drive, etc.) via OAuth.
• git-teacher – Interactive Git/GitHub onboarding with analogies.
• vibe-sunsang – AI mentor that analyses your conversations and produces growth reports.
• skillers-suda – Four expert agents debate your idea and output a ready‑to‑use Claude Code skill.

Trust & setup

• Most plugins run entirely inside Claude Code and need no external credentials.
• Plugins that talk to outside services clearly label the requirement:
  • nopal – Google Workspace OAuth (one‑time login via the gws CLI).
  • insane-review – Requires an active logged‑in ChatGPT Plus/Pro browser session.
  • pumasi – Needs the Codex CLI installed locally.
• All plugins are MIT‑licensed and the source for each lives in its own sub‑module with a dedicated README.

Why it matters – Claude Code is a powerful LLM‑driven IDE, but it hits practical limits (blocked web content, lack of design data, need for stronger model reviews, etc.). GPTaku Plugins turn those limits into plug‑and‑play capabilities, letting developers stay inside the same conversational environment while accessing the web, design assets, research pipelines, and project‑management tools.
