Fix Feature Bug

Fix a bug in a feature or module.

Configuration is read from foundation-config.yaml.

This workflow can also be triggered automatically via .claude/rules/bug_fix_detection.md (or foundation/agent_instructions/cursor_rules/bug_fix_detection.md) when you mention bug/error-related patterns in natural language (e.g., "bug", "error", "fix", "broken"). Both paths execute the same workflow.

Workflow

1. Load configuration:

   • Read foundation-config.yaml for bug fix settings
   • Check if error classification is configured
   • Determine feature/module directory structure

2. Identify feature/module from error, path, or context.

3. Load relevant documents:

   • Repository navigation guide (if configured)
   • Feature/module spec and manifest (if available)
   • Error classification documentation (if configured)
   • Relevant subsystem/module documentation (if configured)

4. Classify bug (if error classification configured):

   • Use configured error classification system
   • Determine correction approach based on class

5. Apply correction rules:

   • If Class 1 (Implementation bug): Patch code only
   • If Class 2 (Spec bug): Update spec/manifest first, then align code/tests
   • If Class 3 (Architectural bug): Update subsystem/architecture docs first, then rebuild
   • If no classification: Fix bug and update relevant documentation

6. Always add a regression test.

7. Run tests:

   • Run configured test commands
   • Verify fix doesn't break existing functionality

8. Output:

   • Error class (if classification configured)
   • Reason for classification
   • Corrected files
   • Tests added/updated

Error Classification (Configurable)

If development.bug_fix.error_classification.enabled: true in foundation-config:

• Class 1: Implementation bug - spec is correct, code doesn't match spec
  • Action: Patch code only
• Class 2: Spec bug - spec is incomplete or wrong, code matches spec but spec is wrong
  • Action: Update spec/manifest first, then align code/tests
• Class 3: Architectural bug - subsystem/architecture docs are wrong or incomplete
  • Action: Update architecture docs first, then rebuild

Configuration

Bug fix workflow uses settings from foundation-config.yaml:

development:
  bug_fix:
    enabled: true
    error_classification:
      enabled: false  # Enable if you have error classification system
      classes:
        - name: "Class 1"
          description: "Implementation bug"
          correction: "Patch code only"
        - name: "Class 2"
          description: "Spec bug"
          correction: "Update spec first, then code"
        - name: "Class 3"
          description: "Architectural bug"
          correction: "Update architecture docs first"
    require_regression_test: true
    test_commands:  # Optional, repo-specific test commands
      - "npm test"
      - "npm run test:integration"

Inputs

• feature_id or module_name (optional): The feature/module identifier to fix
