Architectural Planning for Codex CLI, Claude Code & Cursor

Q: How is this different from Codex CLI or Claude Code?

PlanToCode provides architectural pre-planning before you use Codex, Claude Code, or Cursor. It adds file discovery, multi-model synthesis, and merge instructions that complement the execution phase of those tools.

You can't possibly remember to mention every webhook, cache, background job, and API consumer that depends on that one function. That's how regressions sneak in.

The newest, most advanced models are brilliant at code, blind to architecture.
See the full scope, guide it to the right files, pick the approach that fits your system.

When AI needs architectural context

AI fixes the symptom in /components, misses the cause in /config

Guide it to the right abstraction layer with file discovery

One plan catches edge cases, another handles error states, third adds types

AI architect combines complementary insights into complete implementation

AI drifts from your requirements, builds what it thinks you want

AI architect keeps plans aligned with your actual goals, no drift

Your change breaks three downstream services, discovered in prod

File discovery maps all dependencies upfront, catches impacts early

These aren't "pain points." They're moments where you need visibility and control
before committing to an approach. That's what we built.

What you actually get

Know what will be changed before it happens

File discovery shows exact impact. See which files each plan touches. No surprises.

See how it works

AI architect merges plans with your guidance

Guide the merge with your architectural requirements. AI consolidates complementary details from multiple runs into one comprehensive plan

See how it works

One-click prompts that work

Copy buttons for your battle-tested prompts. No more retyping "make it type-safe" 20 times.

See how it works

Execution with full control

Review the plan, verify the scope, then execute. Or paste into your IDE's chat.

Why this matters now

AI models write excellent code

Modern models are capable. But they don't know **your** architecture, **your** patterns, **your** constraints.

Codebases are interconnected systems

Change the user service, break the mobile app. Update this interface, affect three microservices. AI doesn't see these connections.

Every IDE has AI now

Popular AI coding tools are brilliant at the micro level. You need something that sees the macro.

Frequently Asked Questions

Everything you need to know about PlanToCode

PlanToCode provides architectural pre-planning **before** you use Codex, Claude Code, or Cursor. It adds file discovery, multi-model synthesis, and merge instructions that complement the execution phase of those tools.

Yes. PlanToCode works alongside Codex CLI, Claude Code, Cursor, and Windsurf. Generate plans in PlanToCode, then execute in your preferred tool with full context.

Run the same task multiple times with different AI models. Each run surfaces different implementation details. PlanToCode merges them into one comprehensive plan with source attribution.

How it works

File Discovery

Multi-stage workflow surfaces the right files before you plan

Generate Plans

Run multiple models with different perspectives and token guardrails

AI Merges + You Guide

Provide merge instructions, AI consolidates complementary details from multiple runs

Execute

Run in terminal or paste into your AI coding tool

Who's using this

Senior engineers

"AI kept fixing symptoms, not causes. Now I guide it to the right abstraction layer first. File discovery shows the real architecture before any code is written."

CLI agent users

"My CLI agent would miss edge cases or break existing features. Now the AI architect catches gaps and regressions in plans before they hit my codebase."

Cursor & Windsurf users

"IDE agents lack architectural context. Now my AI architect pre-plans the right approach, considering all system impacts. Then I paste the validated plan into Cursor."

The progress you actually make

Ship complex features with confidence

AI architect merges complementary insights from multiple plans into complete implementation

Guide merges with your expertise

Tell AI what you like, what to avoid. It follows your architectural decisions surprisingly well

Execute with full visibility

See exact scope before running. Integrated terminal or paste to your IDE

AI generates the code. You architect the solution.
