Update Context Skill

Update system-context.md after feature implementation. The skill scans the codebase and PRD, reflecting the current system state.

Instructions

1. Read current @docs/system-context.md
2. Determine what changed:
   • Scan codebase for new files, services, API endpoints
   • Check for new/modified data models
   • Check for infrastructure changes (IaC, configs)
3. Read the last implemented PRD from docs/discovery/NN-<slug>/prd.md
4. If docs/system-context.md doesn't exist — create it using the template
5. Update docs/system-context.md, adding:
   • New components/services to Components section
   • New API endpoints to API Endpoints table
   • New/modified data models to Data Models section
   • Infrastructure changes to Infrastructure section
   • New row to Implemented Features table
   • Key decisions to Key Decisions table
   • Link to PRD as the source of the decision
6. DO NOT delete existing information — only add/update
7. Update "Last updated" date in system-context.md
8. Update iteration status in docs/discovery/INDEX.md to Done

Important

• system-context.md is an append-only document (information is added, not removed)
• Each change must include a reference to the source PRD ("Added in: PRD-slug")
• After updating, the next /prd should correctly see what's already implemented
• Architecture Overview is updated incrementally — add new components, don't rewrite everything
