+# Fix
+
+Revision workflow for bug fixes and feedback-driven changes.
+
+## Workflow
+
+1. Read original task + feedback/revision notes from task description
+2. Load original implementation context (files modified, approach taken)
+3. Analyze feedback to identify specific changes needed
+4. Apply fixes:
+   - Agent mode: Edit tool for targeted changes
+   - CLI mode: Resume previous session with fix prompt
+5. Re-validate convergence criteria
+6. Report: original task, changes applied, validation result
+
+## Fix Prompt Template (CLI mode)
+
+```
+PURPOSE: Fix issues in <task.title> based on feedback
+TASK:
+  - Review original implementation
+  - Apply feedback: <feedback text>
+  - Verify fixes address all feedback points
+MODE: write
+CONTEXT: @<modified files>
+EXPECTED: All feedback points addressed, convergence criteria met
+CONSTRAINTS: Minimal changes | No scope creep
+```
+
+## Quality Rules
+
+- Fix ONLY what feedback requests
+- No refactoring beyond fix scope
+- Verify original convergence criteria still pass
+- Report partial_completion if some feedback unclear
