Review Codex

Determine Review Type

Check which files exist:

1. If .task/plan-refined.json exists and no .task/impl-result.json -> Plan Review
2. If .task/impl-result.json exists -> Code Review

Session Management

Check if .task/.codex-session-active exists:

• If yes: This is a subsequent review (Codex has reviewed before)
• If no: This is a first review

For Plan Reviews

1. Read .task/plan-refined.json
2. Invoke Codex using Bash:

codex exec \
  --full-auto \
  --output-schema ".task/plan-review.schema.json" \
  -o .task/review-codex.json \
  "Review the plan in .task/plan-refined.json. Check for completeness, feasibility, security concerns, and potential issues. Apply standards from skill/multi-ai/reference/standards.md."

For Code Reviews

1. Read .task/impl-result.json
2. Invoke Codex using Bash:

codex exec \
  --full-auto \
  --output-schema ".task/review-result.schema.json" \
  -o .task/review-codex.json \
  "Review the implementation in .task/impl-result.json. Identify bugs, security issues, code style violations. Apply standards from skill/multi-ai/reference/standards.md."

For Subsequent Reviews

If .task/.codex-session-active exists, use resume:

codex exec \
  --full-auto \
  --output-schema ".task/review-result.schema.json" \
  -o .task/review-codex.json \
  resume --last \
  "Re-review the changes. Previous issues should be addressed."

After Codex Completes

1. Mark session as active: touch .task/.codex-session-active
2. Read .task/review-codex.json to get the result
3. Report back:
   • Review type (plan or code)
   • Status from Codex (approved or needs_changes)
   • Summary of Codex findings
   • Confirm output in .task/review-codex.json

If Codex Fails

If the Bash command fails or output is invalid:

1. Report the error to the user
2. Check if codex CLI is installed and authenticated
3. Try the command again with verbose output
4. If persistent failure, ask user to verify Codex CLI setup
