Codex Prompt Generator
Codex is OpenAI's repo-aware coding agent: it takes a scoped task, works across files, runs the result, and hands back a reviewable change, often as a diff or pull request. Its output is only as reviewable as the task was bounded. Archly turns your idea into exactly that kind of bounded task.
Why prompting Codex is different
- Codex returns changes for review, so unscoped asks like 'improve the app' produce diffuse diffs nobody can evaluate. Small, verifiable units beat sprawling requests.
- It inherits your repository's stack and conventions, so the prompt should name the files and areas involved rather than describing an app from scratch.
- Without a stated test or verification signal, you get output you cannot confirm. The success check belongs in the prompt itself.
How Archly structures prompts for Codex
- The Codex platform profile frames each feature as one well-bounded task with explicit inputs, outputs, and acceptance criteria.
- Archly's intake captures which tests should pass and how to run them, so every task ships with its own verification signal.
- Repo-wide conventions get separated out for your AGENTS.md file instead of bloating every individual task.
Frequently asked questions
How should I scope tasks for Codex?
One coherent change per task, small enough that the resulting diff is reviewable in one sitting. Reference the files involved, state the acceptance criteria, and name the tests that prove it works.
What is AGENTS.md and does Archly use it?
AGENTS.md is a rules file Codex reads for repo conventions. Archly helps you split durable conventions into that file while keeping individual task prompts lean.
Is Codex a scaffolding tool like Lovable or Bolt?
No. Codex operates on an existing codebase. If you are starting from zero, scaffold with a builder like Lovable or Bolt first, then use Codex for scoped changes. Archly has profiles for both workflows.
Archly also works with
Lovable, Bolt, v0, Cursor, Replit, Claude Code, OpenCode, Antigravity, AI Studio, Anything AI, Base44, and more.
