Documentation

README

Excerpt

Code Reviewer

Two responsibilities: requesting review (dispatching a reviewer subagent) and receiving review (acting on feedback with technical rigor). Review early, review often. Verify before implementing feedback.

Part 1: Requesting Review

Mandatory after: each task in SDD, each planned execution wave, each major feature, before merge. Optional: when stuck, before refactoring, after fixing complex bugs.

This is the opening of the README. Read the full README on GitHub.
