+# Step 4: Self-Check
+
+**Goal:** Audit completed work against tasks, tests, AC, and patterns before external review.
+
+---
+
+## AVAILABLE STATE
+
+From previous steps:
+
+- `{baseline_commit}` - Git HEAD at workflow start
+- `{execution_mode}` - "tech-spec" or "direct"
+- `{tech_spec_path}` - Tech-spec file (if Mode A)
+- `{project_context}` - Project patterns (if exists)
+
+---
+
+## SELF-CHECK AUDIT
+
+### 1. Tasks Complete
+
+Verify all tasks are marked complete:
+
+- [ ] All tasks from tech-spec or mental plan marked `[x]`
+- [ ] No tasks skipped without documented reason
+- [ ] Any blocked tasks have clear explanation
+
+### 2. Tests Passing
+
+Verify test status:
+
+- [ ] All existing tests still pass
+- [ ] New tests written for new functionality
+- [ ] No test warnings or skipped tests without reason
+
+### 3. Acceptance Criteria Satisfied
+
+For each AC:
+
+- [ ] AC is demonstrably met
+- [ ] Can explain how implementation satisfies AC
+- [ ] Edge cases considered
+
+### 4. Patterns Followed
+
+Verify code quality:
+
+- [ ] Follows existing code patterns in codebase
+- [ ] Follows project-context rules (if exists)
+- [ ] Error handling consistent with codebase
+- [ ] No obvious code smells introduced
+
+---
+
+## UPDATE TECH-SPEC (Mode A only)
+
+If `{execution_mode}` is "tech-spec":
+
+1. Load `{tech_spec_path}`
+2. Mark all tasks as `[x]` complete
+3. Update status to "Implementation Complete"
+4. Save changes
+
+---
+
+## IMPLEMENTATION SUMMARY
+
+Present summary to transition to review:
+
+```
+**Implementation Complete!**
+
+**Summary:** {what was implemented}
+**Files Modified:** {list of files}
+**Tests:** {test summary - passed/added/etc}
+**AC Status:** {all satisfied / issues noted}
+
+Proceeding to adversarial code review...
+```
+
+---
+
+## NEXT STEP
+
+Proceed immediately to `./step-05-adversarial-review.md`.
+
+---
+
+## SUCCESS METRICS
+
+- All tasks verified complete
+- All tests passing
+- All AC satisfied
+- Patterns followed
+- Tech-spec updated (if Mode A)
+- Summary presented
+
+## FAILURE MODES
+
+- Claiming tasks complete when they're not
+- Not running tests before proceeding
+- Missing AC verification
+- Ignoring pattern violations
+- Not updating tech-spec status (Mode A)
