Claude Codex Bridge

Use this skill for bidirectional Claude-Codex review loops.

• Claude execution -> Codex audit -> Claude repair feedback.
• Codex execution -> Claude audit -> Codex repair feedback.

Default to automatic return after audit unless the user explicitly asks for audit-only mode.

Bridge delivery defaults to cli mode through the helper scripts. In cli mode, the target CLI performs the audit and prints the result back into this same conversation; do not use desktop App automation.

CLI runs are tracked under .agent-bridge/runs/<runId>/. Use .agent-bridge/runs/latest.json to inspect the latest run. A completed run has status: success and cli_done.json; a failed run has status: error and bridge_error.json. If a run still says status: started, it is in progress or was interrupted; do not treat that as a successful audit.

CLI preconditions: Codex CLI must be runnable for Codex audits. The bridge tries AGENT_BRIDGE_CODEX_BIN, then codex from PATH, then /Applications/Codex.app/Contents/Resources/codex. claude --version plus claude auth status must work for Claude audits. If the Claude auth preflight fails, tell the user to run Claude Code login/status rather than treating it as an App handoff failure.

If a CLI is missing or auth fails, run:

node "$HOME/.agent-bridge/bridge.mjs" doctor

Use the doctor's suggested fix. Common fixes are:

npm install -g @openai/codex
npm install -g @anthropic-ai/claude-code
claude auth login
claude auth status

If Codex Desktop is installed, the bridge can use /Applications/Codex.app/Contents/Resources/codex without an npm Codex install.

Use --delivery current, --delivery ax, or --delivery new only when the user explicitly asks to operate the desktop App UI. In ax or current mode, treat bridge success as macOS paste/submit automation completion. If the bridge reports a focus error or non-zero exit, do not tell the user the feedback was delivered; report the error and ask them to bring the target app conversation to the front before retrying.

Send Claude To Codex For Audit

When the user wants Codex/GPT-5.5 to audit Claude's latest work, create a concise handoff with:

• Original user goal.
• What was changed, including important file paths.
• Commands run and verification results.
• Anything uncertain, skipped, or risky.
• A direct request for Codex to audit correctness, completeness, safety, and missing verification, then automatically return the Suggested Reply To Claude.

Do not hide failed commands or partial work. Codex needs the sharp edges.

Send To Codex

Send the handoff through the local bridge:

node "$HOME/.claude/skills/claude-codex-bridge/scripts/send-to-codex.mjs"

Pass the full handoff on stdin. The bridge writes a Markdown transfer file under .agent-bridge/inbox/, writes durable run evidence under .agent-bridge/runs/<runId>/, runs Codex CLI in read-only mode, and returns the audit as command output in this same Claude conversation.

If the bridge script is missing, tell the user to install the global bridge runtime or run this from a workspace that contains agent-bridge/bridge.mjs.

Audit Codex From Claude

When a bridge prompt asks Claude to audit Codex/GPT-5.5 execution, read the provided transfer file first. If no file path is provided, use the newest .agent-bridge/inbox/*audit-codex-to-claude.md.

Output:

Findings
- [P0/P1/P2/P3] Concrete issue with file/command evidence when available.

Missing Verification
- Tests, commands, screenshots, or checks Codex should still run.

Suggested Reply To Codex
<a concise message the user can send back to Codex>

Prioritize behavioral bugs, incomplete work, risky commands, missing validation, and places where Codex claimed success without evidence. If no issues are found, say so clearly and still mention residual risk.

Default CLI path: read the newest handoff, produce the audit, and leave the result in .agent-bridge/runs/<runId>/audit.md plus .agent-bridge/outbox/latest-claude-audit.md. The command output is already the return path to this conversation.

Only when using App delivery modes, write Suggested Reply To Codex to:

.agent-bridge/outbox/latest-reply-to-codex.md

Then run:

node "$HOME/.claude/skills/claude-codex-bridge/scripts/send-file-to-codex.mjs" .agent-bridge/outbox/latest-reply-to-codex.md

If the command exits successfully, say the bridge sent paste/submit automation to Codex. If it fails, include the error and do not claim Codex received the feedback. If the user says "only audit", "do not forward", or equivalent, stop after showing the audit.
