plan-execute（计划执行）

Plan Execute Skill

Purpose

When the user runs /plan-execute {plan-file-path}, start the "orchestrated plan execution" workflow:

1. I (Claude Code) ask Codex to implement the code according to the plan.
2. After Codex finishes, I review the generated code.
3. I write the review into the reviews/ directory, then ask Codex to inspect and fix the issues.
4. Repeat until the code quality bar is met.

Core principle: I do not write or edit code myself. I only do two things: review code and orchestrate Codex. All code changes, including implementation and fixes, are performed by Codex.

Usage

/plan-execute plans/my-feature-plan.md

Session Reuse

After each Codex invocation, extract session_id=xxx from the script output and save it as the session ID for the current task. In later Codex calls for the same task, pass --session <id> to reuse context so Codex remembers prior implementation and fix history instead of rereading the entire codebase every time.

My Workflow (Claude Code)

Step 1: Read the Plan and Split Execution Steps

Read the specified plan file and understand:

• The overall goal and scope of the plan
• The list of files to create or modify
• The order of implementation steps
• Relevant project conventions, especially from CLAUDE.md

If the plan already contains a checklist (- [] / - [x]), use those items as execution units. If it does not define clear steps, split the work into reasonable batches, with no more than 5 file changes per batch.

Step 2: Ask Codex to Implement the Code

Use the /codex skill and give Codex the following instruction:

Implement the code according to the plan in {plan-file-path}.

Current execution scope: {specific step or batch description}

Requirements:
- Follow the design in the plan exactly. Do not improvise beyond it.
- Obey the Code Quality Hard Limits defined in `CLAUDE.md`.
- Single file <= 800 lines, single function <= 50 lines, nesting <= 3 levels
- Run `pnpm build` after implementation to confirm compilation succeeds
- If the plan includes a checklist, mark completed steps as `[x]`

After implementation, list all changed files and provide a summary of each change.

Step 3: Review Codex Output (My Core Responsibility)

After Codex finishes, I perform a code review. Important: I only read code and write reviews. I never directly modify source files.

1. Read every changed file and review them one by one.
2. Compare against the plan to verify the implementation matches the intended design.
3. Check code quality, including:

- Whether it violates the Code Quality Hard Limits - Whether it introduces security risks - Whether error handling is missing - Whether naming and organization are clear - Whether it follows existing project patterns

1. Run pnpm build to confirm the compilation status.

Step 4: Write the Review and Hand Fixes Back to Codex

Append the review to reviews/{topic}-review.md (shared with plan-review):

---

## Code Review Round {N} — {YYYY-MM-DD}

**Scope**: {code scope covered in this review}
**Build Status**: PASS / FAIL

### Issues

#### Issue 1 ({severity}): {title}
**File**: {file-path:line}
{issue description}
**Fix**: {specific fix recommendation}

...

### Verdict: NEEDS_FIX / APPROVED

If Verdict: NEEDS_FIX, call /codex and have Codex fix the issues instead of editing them myself:

Read the latest Code Review round in {review-file-path}.
Check each issue one by one. Fix the valid issues, and explain why any disputed item is not actually a problem.
After making fixes, run `pnpm build` to confirm compilation succeeds.
List the issues that were fixed and the corresponding code changes.

If Verdict: APPROVED, skip to Step 6.

Step 5: Verify Fixes and Iterate

After Codex applies fixes, I review again, still without editing code directly:

• Check whether each issue was truly fixed
• Check whether the fixes introduced new problems
• If issues remain, write a new review round and hand it back to Codex for another fix pass (repeat Step 4)
• If everything passes, mark the review as Verdict: APPROVED

Step 6: Update Plan Progress

After each batch is completed, ask Codex to update the checklist in the plan file (- [] -> - [x]). If unfinished steps remain, go back to Step 2 for the next batch. Once all work is complete, move to the wrap-up.

Step 7: Wrap Up

Report the following to the user:

• Which steps were completed
• How many code review rounds were needed
• Which major issues were fixed
• Final build status
• List of changed files
• Path to the review log file

Review Severity Levels

Verdict rules:

• If any Critical or High issue exists -> NEEDS_FIX
• If all issues are Medium or below -> APPROVED with optional improvement notes

File Convention

• Share the same review file as plan-review: reviews/{topic}-review.md
• {topic} is the plan file name without .md
• Both plan review rounds and code review rounds are appended to the same file
• Distinguish them by heading: ## Round {N} for plan review and ## Code Review Round {N} for code review
