API Route Planner
Plans build-ready product specs, app flows, and implementation checklists for solo builders and vibe coders. Use when Codex needs to turn goals, constraints, and context into a sequenced plan with decisions, dependencies, and QA criteria.
What this skill helps you do
API Route Planner turns a repeated app building task into a narrow operating procedure your agent can follow with less drift, clearer inputs, and a stronger verification pass.
Best-fit workflow
- Use API Route Planner when the task belongs to app building and needs a repeatable workflow instead of a one-off prompt.
- Start with the project context, target audience, constraints, source material, and the exact artifact you want the agent to produce.
- Ask the agent to run the skill, produce the requested output, and finish with the built-in verification checklist before you use the result.

Expected output
A structured first-pass artifact that follows the skill workflow.
Clear assumptions, missing inputs, and decisions the agent made while working.
A final QA pass against the quality bar so weak or generic output gets caught before shipping.
