Claude Agent System

Turn Claude into your personal development team. Plugin skills that handle everything — from deep planning through implementation to code review, with parallel agent swarms and automatic quality gates.

v7.20.0 — State directory moved out of .claude/

All CAS state (plans, mailboxes, wave files) moved from .claude/plans/ to .cas/plans/. Claude Code treats .claude/ as a sensitive config directory, causing every plan/mailbox write to trigger a permission prompt — even in dontAsk mode. This blocked all swarm skills (Hydra, Legion, Siege, Spectre) in practice. 112 path references updated across 27 files. Also includes v7.19.0: all swarm teammates can now invoke any installed plugin skill via the Skill tool (24 templates updated).

The Claude Agent System is distributed exclusively as a Claude Code plugin. If you previously installed via the legacy setup script, uninstall the old files first:

rm -rf .claude/commands .claude/workflows .claude/middleware .claude/agents
/plugin marketplace add Kasempiternal/Claude-Agent-System
/plugin install cas

Quick Start

/plugin marketplace add Kasempiternal/Claude-Agent-System
/plugin install cas

Done! You now have 14 skills: /zk, /spectre, /gonk-test, /siege, /legion, /pcc, /pcc-opus, /hydra, /review, /cyberconan, /systemcc, /l30, /setup-swarm, and /setup-hooks. The Gonk MCP server (headless browser E2E testing) is bundled and auto-registers on install.

Anti-Vibe Coding Philosophy

"Vibe coding" = typing a prompt, accepting whatever the AI outputs, hoping it works.

This system is the opposite. Every skill enforces structure:

What Vibe Coding Does	What This System Does
Blindly accepts AI output	Parallel code review agents
No validation	Build config detection + linting enforcement
No learning	Session memory - learns your patterns and mistakes
No quality gates	Decision engines with complexity/risk/scope analysis
Hope it works	Post-execution validation + auto-fix critical issues

/gonk-test - E2E Frontend Testing with Gonk MCP NEW

Headless browser E2E testing, powered by direct Chrome DevTools Protocol. Describe what you want to test in plain English — Gonk launches a headless browser, navigates, interacts, asserts, and reports results. No visible browser needed.

/gonk-test https://localhost:3000
/gonk-test "test the login flow — fill email and password, click submit, verify dashboard loads"
/gonk-test "check that the checkout page has no JS errors and all API calls return 200"
/gonk-test "verify the landing page renders correctly on iPhone 15"

Why Gonk?

The Chrome extension MCP is slow and requires a visible browser. Maestro proved that headless, accessibility-tree-based testing is dramatically faster — but only works for mobile. Gonk brings this to the web.

	Chrome Extension MCP	Playwright MCP	Gonk
Speed	Slow (extension relay)	Medium (Playwright layer)	~5x faster (direct CDP)
Browser	Must be visible	Headless available	Headless, zero UI
Output	Screenshots	Accessibility snapshots	Hybrid AX+DOM with smart diffing
Framework awareness	None	None	React/Vue/Svelte/Angular component trees
Network	Basic logging	Basic logging	Full interception + mocking
Assertions	None	None	AI-native with self-correction suggestions
Flows	None	None	Maestro-style YAML record/replay
Token efficiency	Full snapshots	Full snapshots	Diff mode: ~50 tokens vs ~2000
