/code-to-prd

Slash Command Source

Reverse-engineer a frontend codebase into a complete Product Requirements Document.

Usage

/code-to-prd                    # Analyze current project
/code-to-prd ./src              # Analyze specific directory
/code-to-prd /path/to/project   # Analyze external project

What It Does

  1. Scan — Run codebase_analyzer.py to detect framework, routes, APIs, enums, and project structure
  2. Scaffold — Run prd_scaffolder.py to create prd/ directory with README.md, per-page stubs, and appendix files
  3. Analyze — Walk through each page following the Phase 2 workflow: fields, interactions, API dependencies, page relationships
  4. Generate — Produce the final PRD with all pages, enum dictionary, API inventory, and page relationship map

Steps

Step 1: Analyze

Determine the project path (default: current directory). Run the frontend analyzer:

python3 {skill_path}/scripts/codebase_analyzer.py {project_path} -o .code-to-prd-analysis.json

Display a summary of findings: framework, page count, API count, enum count.

Step 2: Scaffold

Generate the PRD directory skeleton:

python3 {skill_path}/scripts/prd_scaffolder.py .code-to-prd-analysis.json -o prd/

Step 3: Fill

For each page in the inventory, follow the SKILL.md Phase 2 workflow: - Read the page's component files - Document fields, interactions, API dependencies, page relationships - Fill in the corresponding prd/pages/ stub

Work in batches of 3-5 pages for large projects (>15 pages). Ask the user to confirm after each batch.

Step 4: Finalize

Complete the appendix files: - prd/appendix/enum-dictionary.md — all enums and status codes found - prd/appendix/api-inventory.md — consolidated API reference - prd/appendix/page-relationships.md — navigation and data coupling map

Clean up the temporary analysis file: 

rm .code-to-prd-analysis.json

Output

A prd/ directory containing: - README.md — system overview, module map, page inventory - pages/*.md — one file per page with fields, interactions, APIs - appendix/*.md — enum dictionary, API inventory, page relationships
