| name | codex-prompt-generator |
| description | Generate clear, ready-to-paste prompts for Codex that turn rough requests into executable instructions with scope, constraints, acceptance criteria, and validation steps. Use when you want a high-quality prompt before asking Codex to implement features, fix bugs, refactor code, review changes, write tests, or perform deployments. |
Codex Prompt Generator
Overview
Transform an incomplete task request into a production-ready Codex prompt.
Return one final prompt block the user can paste directly into Codex.
Workflow
- Extract task intent, target repo or folders, and expected outcome.
- Normalize missing details into explicit assumptions.
- Add implementation constraints, validation commands, and handoff format.
- Output only the final prompt unless the user asks for alternatives.
Prompt Output Contract
Use this structure in every generated prompt.
You are working in: <repo-or-path>
Mode: Plan
Objective:
<single outcome-focused objective>
Scope:
- In scope: <what to change>
- Out of scope: <what not to touch>
Requirements:
- <functional requirement 1>
- <functional requirement 2>
Constraints:
- Preserve backward compatibility for <contracts/fields/behaviors>
- Do not revert unrelated local changes
- Keep edits minimal and targeted
- Run in Plan Mode first; do not start implementation without a plan
Implementation Notes:
- Update both frontend and backend when contracts or payloads change
- Add or update tests for meaningful behavior changes
Validation:
- Run: <command 1>
- Run: <command 2>
- Run: <command 3>
- If any command fails, report the exact failure and stop
Handoff:
- Summarize changed files and behavior impact
- List validation commands with pass/fail status
- List risks, compatibility notes, and follow-up items
Generation Rules
- Prefer precise verbs: implement, refactor, validate, audit, migrate, deploy.
- Convert vague words into measurable checks.
- Include exact directories when known.
- Include acceptance criteria for user-visible behavior.
- Keep the final prompt concise enough to execute in one Codex run.
Reusable Blueprints
Use prompt-blueprints.md for task-specific prompt patterns:
- feature implementation
- bug fix
- code review
- test hardening
- release/deploy
