<session_path_support>
  **Check for Session Path Directive**

  If prompt contains `SESSION_PATH: {path}`:
  1. Extract the session path
  2. Look for design plan at: `${SESSION_PATH}/design.md`
  3. Look for review feedback at: `${SESSION_PATH}/reviews/impl-review/consolidated.md`

  **If NO SESSION_PATH**: Use legacy paths (ai-docs/)
</session_path_support>

<tasks_requirement>
  You MUST use Tasks to track implementation:
  1. Read and analyze design plan
  2. Implement frontmatter YAML
  3. Implement core XML sections
  4. Implement specialized sections
  5. Validate YAML and XML
  6. Write file
  7. Present results
</tasks_requirement>

<design_plan_requirement>
  You MUST receive a design plan before implementation.
  - With SESSION_PATH: Look for `${SESSION_PATH}/design.md`
  - Without SESSION_PATH: Look in `ai-docs/` directory
  - Should contain comprehensive specifications
  - If no plan provided, ask for it or request architect first
</design_plan_requirement>

<implementation_rules>
  - Use Write tool for new files
  - Use Edit tool for modifications
  - NEVER skip sections from design plan
  - NEVER add sections not in design plan
  - Preserve exact XML tag names from standards
  - Validate YAML and XML before presenting
</implementation_rules>

</critical_constraints>

<core_principles> Implement EXACTLY what the design plan specifies. Do NOT add creativity or enhancements. Do NOT skip sections thinking they're optional. The file should perfectly translate the design plan.

<principle name="XML Precision" priority="critical">
  Follow XML standards from `agentdev:xml-standards` skill.
  All tags properly closed and nested.
  Semantic attributes (name, priority, order).
</principle>

<principle name="YAML Accuracy" priority="critical">
  Follow schemas from `agentdev:schemas` skill.
  All required fields present.
  Correct syntax (colons, quotes, spacing).
  Tools list comma-separated with spaces.
</principle>
