Execute BASE PRP

PRP File: $ARGUMENTS

Mission: One-Pass Implementation Success

PRPs enable working code on the first attempt through:

• Context Completeness: Everything needed, nothing guessed
• Progressive Validation: 4-level gates catch errors early
• Pattern Consistency: Follow existing codebase approaches
• Read PRPs/README.md to understand PRP concepts

Your Goal: Transform the PRP into working code that passes all validation gates.

Execution Process

1. Load PRP

   • Read the specified PRP file completely
   • Absorb all context, patterns, requirements and gather codebase intelligence
   • Use the provided documentation references and file patterns, consume the right documentation before the appropriate todo/task
   • Trust the PRP's context and guidance - it's designed for one-pass success
   • If needed do additional codebase exploration and research as needed

2. ULTRATHINK & Plan

   • Create comprehensive implementation plan following the PRP's task order
   • Break down into clear todos using TodoWrite tool
   • Use subagents for parallel work when beneficial (always create prp inspired prompts for subagents when used)
   • Follow the patterns referenced in the PRP
   • Use specific file paths, class names, and method signatures from PRP context
   • Never guess - always verify the codebase patterns and examples referenced in the PRP yourself

3. Execute Implementation

   • Follow the PRP's Implementation Tasks sequence, add more detail as needed, especially when using subagents
   • Use the patterns and examples referenced in the PRP
   • Create files in locations specified by the desired codebase tree
   • Apply naming conventions from the task specifications and CLAUDE.md

4. Progressive Validation

   Execute the level validation system from the PRP:

   • Level 1: Run syntax & style validation commands from PRP
   • Level 2: Execute unit test validation from PRP
   • Level 3: Run integration testing commands from PRP
   • Level 4: Execute specified validation from PRP

   Each level must pass before proceeding to the next.

5. Completion Verification

   • Work through the Final Validation Checklist in the PRP
   • Verify all Success Criteria from the "What" section are met
   • Confirm all Anti-Patterns were avoided
   • Implementation is ready and working

Failure Protocol: When validation fails, use the patterns and gotchas from the PRP to fix issues, then re-run validation until passing.
