Composure

A plugin system for Claude Code that catches architecture, security, and quality issues inline — before they reach a commit.

Claude writes code fast. Composure makes sure it writes it right — enforcement hooks that run outside the model at zero token cost, architecture skills that load current patterns instead of stale training data, and a structural code graph that understands your whole project.

This repository is the public home for Composure — the showcase, use-cases, and where you file issues and pull requests. The plugins are distributed as a built artifact (see Install); the source lives in a separate maintained repository.

Install

One command — fresh install or update, macOS / Linux / Windows:

pnpm dlx create-composure

It installs the suite, authenticates your account in the browser, and sets up ~/.composure/. (bunx/npx create-composure also work.) Already inside Claude Code? Run /composure:sync to bring everything current.

Then initialize in any project:

/composure:initialize

Detects your stack, builds the code graph, and pulls in the companion plugins your project needs.

What's in the suite

Plugin	What it does
Composure	Code-quality enforcement, architecture skills, the code graph, Cortex memory, and the task queue — the foundation the others build on.
Sentinel	Security — secret detection on every write, insecure-pattern blocking, dependency CVE auditing, HTTP header analysis.
Testbench	Convention-aware test generation that reads your existing tests to match style, plus coverage nudges.
Shipyard	CI/CD generation and validation — GitHub Actions / GitLab / Bitbucket, Dockerfiles, production-readiness checks.
Design Forge	Premium web design patterns — components, animations, 3D, accessibility-first.

Full skill and hook reference lives on the website — this repo stays focused on showing what the suite does, not documenting every internal.

How it works (three layers)

• Hooks — the enforcer. Shell scripts that fire on every Read/Edit/Write, outside the LLM at zero token cost. The agent can't bypass them.
• Skills — the playbook. Slash commands for architecture, security, testing, CI/CD, and audits — each loading current, framework-specific guidance.
• The graph — the brain. A multi-language SQLite knowledge graph of your whole project (code, migrations, config, docs) Claude queries for instant structural answers.
