arthai is a development toolkit that turns Claude Code into a coordinated engineering team — specialized agents, slash-command workflows, and automatic guardrails, installed as Claude Code plugins and adapted to your codebase.
Claude Code out of the box is one generalist assistant. It’s powerful, but:
| Layer | What it is | Example |
|---|---|---|
| Agents | Specialists with the right model tier for the job — QA, SRE, frontend, backend, planning, research | A Haiku agent handles file searches at 1/60th the cost of Opus |
| Skills | Slash-command workflows that encode multi-step engineering sequences | /fix #42 runs root-cause analysis, scope lock, fix, regression tests |
| Hooks | Automatic behaviors at session lifecycle events | A guard blocks rm -rf and force-pushes before they execute |
| Calibration | /calibrate deep-learns your codebase and seeds a knowledge base; the knowledge graph builds from it automatically at session start and workflows query it |
Fixes match your conventions; QA understands your domain rules |
| Observability | Arth Intelligence — a local dashboard of every session, tool call, agent spawn, and dollar | See exactly what the AI did and what it cost, on your machine |
It also includes role-based flows (/welcome, /wizard) for non-engineers on the team.
