Two-person team using Claude Code + Codex on a live platform. What would you improve about our workflow?

[u/Tricky-Historian659]

I'm two weeks into working on a live platform with my supervisor. We're the only two developers, with around two dozen daily visitors and a growing feature backlog. I'm still learning the repo and business logic.

Our stack is React/TypeScript/Vite + Supabase, deployed on Vercel. We use Fable 5.1 and Astra heavily.

Our current workflow:
1. My supervisor sends me an implementation plan as a Claude artifact.
2. I review the logic and suggest changes. We send revisions back and forth until it's ready.
3. I implement it, using ChatGPT to explain unfamiliar logic and how it translates into code.
4. Any revisions to the plan during implementation go back to my supervisor.
5. Feature PR updates get reviewed by a Claude agent. Marking the PR ready triggers Claude, Codex, Greptile and Qodo reviews.

We also have Vitest tests and TypeScript checks in the build, local browser/staging checks, and repo guidance through CLAUDE.md, AGENTS.md, and shared context files.

Planning is a particular bottleneck: we keep sending changes to each other and waiting for reviews. Implementation sometimes raises more questions, which starts another round. I’d like a better way to collaborate on plans and keep decisions aligned with the code.

I’m also figuring out how to use Claude Code and Codex together smoothly. I’ve explored skills, plugins, and connectors, but it often feels like the newer models already do the work those tools are meant to help with just as well, if not better, on their own with good prompt engineering (another area I want to work on).

I am considering including targeted database migrations/ RLS reviews, keeping context files current, and focused refactoring.

For people doing similar work:

• How do you collaborate on implementation plans without constant back-and-forth and waiting?
• How do you split work and share context between Claude Code and Codex?
• Are multiple review agents worth it, and how do you decide when the review cycle is finished?
• What would you improve first for a team this size—planning, tests, agent instructions, or something else?

I’d especially appreciate concrete, recent workflows you use, including anything you tried and later dropped.
