Agent Claude Code
Part of velocitai
A code-review agent focused on Python and Playwright tests that use the page object model (POM), a way to organize tests by web pages. It looks for bugs and checks rules without changing functionality.
Agent
Part of spectre
Write or update behavioral tests, drive a strict RED→GREEN→REFACTOR loop, or diagnose failing tests for a given working set. Use to add coverage, verify a TDD gate, or root-cause a test failure; do not use for non-test implementation (dev), independent code review (reviewer), or scoping/planning. Returns tests…
