SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validate Codex-generated architecture and planning quality for complex feature or refactor work by ensuring a proper context.md is created and validated before implementation.

Core Features & Use Cases

Collects context.md to establish the planning scope.
Runs the Codex MCP validation prompt to assess architecture and plan quality.
Produces a patch detailing pass/fail status, warnings, and actionable recommendations.

Quick Start

Provide a context.md and trigger the Codex MCP plan validation to generate a patch containing validation notes.

FAQPage Schema

How do I validate architecture and planning quality before a complex feature implementation?▼

Validate architecture quality by collecting context.md, running the validation prompt, and generating a patch with pass/fail status and recommendations. This ensures architectural soundness and planning quality before implementation begins.

What is context.md used for when planning a code refactor?▼

Context.md establishes the planning scope for complex feature or refactor work. It provides the architectural boundaries that the validation prompt reads to accurately assess plan quality and output actionable recommendations.

How do I check if my Codex plan passes architectural validation?▼

Check plan validation by triggering the validation prompt with context.md ready. It outputs a patch containing explicit pass/fail status, warnings, and actionable recommendations detailing the architectural soundness of your planning.

When do I need to verify plan quality for a complex software refactor?▼

Verify plan quality for a complex software refactor when architectural soundness must be guaranteed before writing code. Validating the plan early prevents structural flaws by generating a patch with warnings and actionable recommendations.

Does Codex architecture validation work without a context.md file?▼

Codex architecture validation requires a context.md file to function correctly. Context.md is actively collected to establish the planning scope, which is necessary for the validation prompt to assess architecture and plan quality accurately.

What outputs should I expect from a Codex plan validation prompt?▼

Expect a patch containing detailed validation notes from the plan validation prompt. This output explicitly includes the pass or fail status, identified warnings, and actionable recommendations for improving the architecture before implementation.
