Claude Code vs. Codex: Loops, Graphs, and Harnesses
Details
## Claude Code vs. Codex: Loops, Graphs, and Harnesses
This is a casual pair-programming meetup for developers experimenting with Claude Code, Codex, and agentic coding workflows.
There is no formal presentation and no fixed curriculum. Bring a laptop, a repository, a side project, or a workflow you want to test. We will work in small groups, compare approaches, debug problems, and share what is working.
Possible areas to explore include:
- Building iterative coding-agent loops
- Comparing Claude Code and Codex on the same task
- Designing graph-based agent workflows
- Creating reusable coding harnesses
- Managing context across large repositories
- Running tests and validating agent-generated changes
- Using sandboxes, permissions, and approval steps
- Coordinating subagents or parallel tasks
- Measuring latency, token usage, cost, and completion quality
- Debugging failed or incomplete agent runs
You do not need to be an expert in either tool. This meetup is for people who want hands-on time to experiment, pair with other developers, and learn through building.
Bring something you are working on, or join someone else’s project.
Hosted by CODE.
