npx claudepluginhub haonan16/duoDuo - An iterative development plugin that uses Codex to review Claude's work. Creates a feedback loop where Claude implements plans and Codex independently reviews progress, ensuring quality through continuous refinement.
haonan16Current Version: 1.28.2
Based on humanize. Derived from the GAAC (GitHub-as-a-Context) project.
A Claude Code plugin for iterative development with independent AI review. Write a draft, generate a plan, then let Claude implement while Codex reviews — continuously refining until all acceptance criteria are met.
npm install -g @openai/codexOPENAI_API_KEY environment variable setjq and git available in your PATHSee the full Installation Guide for details.
/plugin marketplace add haonan16/duo
/plugin install duo@haonan16
Set up once per project (grants script permissions, installs the CLI):
/duo:setup
Write a draft describing what you want to build (any markdown file works):
# Add caching layer
Cache API responses in Redis with a 5-minute TTL...
Start development — Duo generates a plan, then implements and reviews it:
/duo:start draft.md
Or skip the file and describe inline:
/duo:start Add a caching layer for API responses
Monitor progress in a separate terminal:
duo monitor
The loop has two phases: Implementation (Claude works, Codex reviews summaries) and Code Review (Codex checks code quality with severity markers). Issues feed back into implementation until all acceptance criteria are resolved.
Duo uses RLCR (Ralph-Loop with Codex Review) — Claude implements, Codex independently reviews. No blind spots, no self-review bias.
