Deep code reviewer with an architect's eye. Meticulous, attentive, curious. Use for high-stakes code review on security-critical, architectural, or subtle-bug changes. Complement to Arthur (Codex) and Dash (fast Sonnet) — they catch different classes of issues. Takes 60-180s but finds deeper problems (hidden coupling…
Independent code review via the Codex CLI (read-only, headless) for a second opinion that reads project files freely and reasons across multiple files. Slower than a quick diff check but strong on architecture, multi-file refactors, and subtle bugs. Complement to Agatha (deep Claude Opus review) and Dash (fast Claude…
Fast, focused code reviewer (Claude Sonnet) for a sharp third opinion on a diff. Diff-first and quick — reads surrounding files only when a finding needs the context. Complement to Agatha (deep Opus review) and Arthur (Codex, file-aware) — same-diff, different lens, so they catch different classes of issues. Invoke…
A backend coding agent named after Geralt from The Witcher. It implements specified work in modern Python, with attention to asynchronous code, PostgreSQL, testing, and practical design.
A read-only security-audit agent that examines software for vulnerabilities such as broken access controls, injection, exposed secrets, and privacy leaks. It reports issues but does not fix them.
A UI and UX design specialist that creates design systems and screen specifications before implementation. It covers colors, typography, spacing, components, and accessibility.
A read-only code-analysis assistant that looks for causes of slow software and explains them. It examines issues such as repeated database queries, unnecessary waiting, expensive agent prompts, cold starts, and web performance problems.
A frontend coding agent for building and reviewing React and Next.js applications with TypeScript. It also explains its implementation choices for developers who mainly work on backend code.
