# Ensemble Command: /ensemble:validate-requirements This Codex skill mirrors the Ensemble slash command `/ensemble:validate-requirements`. Follow the workflow below, adapt to the current repository, and keep outputs structured. <!-- DO NOT EDIT - Generated from validate-requirements.yaml --> <!-- To modify this file, edit the YAML source and run: npm run generate --> Parse a PRD for all REQ-NNN and AC-NNN-M IDs, parse a TRD for all [satisfies] and [verifies] annotations, and report coverage gaps, orphaned annotations, and missing -TEST task pairs. CI-friendly: exits non-zero on errors, zero on warnings-only. ## Workflow ### Phase 1: Document Parsing **1. Input Validation** Verify that both required arguments are provided and that both files exist on disk. If $ARGUMENTS does not contain two tokens: print 'ERROR: Usage: /ensemble:validate-requirements <prd-path> <trd-path>' and EXIT with code 1. Resolve PRD_PATH from the first argument. If file does not exist: print 'ERROR: PRD file not found: <PRD_PATH>' and EXIT with code 1. Resolve TRD_PATH from the second argument. If file does not exist: print 'ERROR: TRD file not found: <TRD_PATH>' and EXIT with code 1. **2. PRD Parsing** Parse PRD document for all traceability IDs. Extract all REQ-NNN IDs from H3 headings matching '### REQ-NNN:' pattern. Extract all AC-NNN-M IDs from bullet items matching '- AC-NNN-M:' pattern. Build PRD_REQUIREMENTS map: REQ-NNN -> {description, acs: [AC-NNN-M, ...]} Build PRD_AC_SET: fl
