The prompt should point to durable context
A one-message prompt is fragile because it mixes product intent, implementation detail, and done criteria. IdeaPico separates those pieces into documents, then gives Codex a concise handoff.
Codex Handoff Prompt
Give Codex a handoff, not a vague prompt
A strong Codex session needs more than one instruction. IdeaPico creates the product and implementation context first, then gives you a handoff prompt that points the agent at the right documents.
Codex can work better when completion is measurable
The ship document names commands, checks, and expected behavior. That gives the agent a finish line beyond simply producing code that looks plausible.
Useful for founder prototypes and production features
Use the handoff when the task is important enough to need scope, decisions, and review criteria before the agent starts editing files.
Workflow
From idea to handoff packet
The goal is not more planning theater. The goal is enough product and engineering truth for an AI coding agent to make fewer guesses.
- 1
Create the project packet
IdeaPico interviews you and generates the four-file packet.
- 2
Copy the Codex handoff prompt
The prompt tells Codex where the documents are and how to use them.
- 3
Let Codex build against the packet
Codex can plan, edit, test, and report progress against the generated context.
Packet
Four documents, one implementation context
product.md
What Codex is building, for whom, and what must count as complete.
tech.md
How the work should be approached technically, including architecture and data assumptions.
design.md
What the interface should look and feel like, including states and responsive behavior.
ship.md
How Codex should verify the implementation and summarize the finished work.
Example
Codex handoff example
Create an onboarding flow for a team knowledge base with role selection and first document import.
IdeaPico turns that into:
- Defines owner/member roles, import states, and first-run success criteria.
- Adds technical assumptions for auth, storage, and document parsing.
- Gives Codex verification steps for onboarding, import failure, and empty workspace states.
FAQ
What is a Codex handoff prompt?
A Codex handoff prompt is the final instruction that tells Codex what context to use, what to build, and how to verify the work. IdeaPico backs that prompt with structured documents.
Why does the handoff include multiple documents?
Product, technical, design, and shipping concerns are different. Splitting them makes the task easier for an agent to follow and easier for a human to review.
Can the same handoff work with other coding agents?
Yes. The packet is plain markdown, so it can be used with Codex, Cursor, Claude Code, Windsurf, v0, or a human teammate.
