Strong fit
- Implementation followed by independent review.
- A long task with a clear phase boundary.
- Parallel work with non-overlapping file ownership.
Multi-Agent workflow
Use Codex and Claude Code on the same project
Let Codex implement a bounded change, then start a separate Claude Code Session against the same saved Workspace files for review or continuation. Continuity comes from inspectable project state—not from pretending the Agents share private reasoning.
- Shared project files
- Separate Sessions
- Reviewable handoff
01 · Working evidence
Share project state, not hidden reasoning
Files, diffs, checks, Previews, and approved decisions can carry the work between Sessions while each Agent keeps its own execution loop.01CodexShared project files

03Claude CodeReviewable handoff
Give each Agent a separate bounded Session and make files, checks, and review evidence carry the handoff.

A practical Codex-to-Claude Code handoff
Give each Agent a bounded role and make the saved project state the evidence both must inspect.- 01
Codex implements
Define the outcome, ownership, protected files, and checks. Save the changed files, diff summary, commands, and open risks.
- 02
A person inspects
Review the current files and Preview, then write a concise handoff with goal, state, checks, risk, and next action.
- 03
Claude Code reviews
Start a separate Session, verify the handoff against the files, and continue only within the assigned boundary.
03 · Task fit
Use two Agents when the phase boundary adds value
Implementation followed by an independent review is stronger than two Agents editing the same files without ownership.Not the right fit
- Two Sessions editing the same files without coordination.
- A tiny task where handoff costs more than it saves.
- A workflow expecting access to another Agent's private reasoning.
04 · Boundaries
The Workspace preserves artifacts, not assumptions
The next Agent should verify the current files and checks rather than trusting a transcript summary.- 01
Separate Sessions can still create conflicting edits.
- 02
Agent.Space does not automatically resolve semantic merge conflicts.
- 03
The live selector governs compatible models and controls for each Agent.

Working with two Agent harnesses
Keep the shared and separate parts of the workflow clear.
Start in one Space
Keep the project stable while the Agent changes
Give each Agent a separate bounded Session and make files, checks, and review evidence carry the handoff.
