Iterative Loop

# Define task with clear completion criteria
TASK="Implement user authentication with JWT.
Success criteria:
- All unit tests pass
- Integration tests pass
- No TypeScript errors
- Security audit passes
Output <promise>COMPLETE</promise> when all criteria met."

# Execute iterative loop (conceptual)
while ! task_complete; do
  claude_execute "$TASK"
  check_completion_criteria
done

# Using claude-flow hooks for iterative task
npx --no-install ruflo hooks pre-task --description "Implement auth with iteration" --taskId "auth-impl"

# Store iteration state in memory
npx --no-install ruflo memory store \

✅ All unit tests pass (npm test returns exit code 0)
✅ Coverage > 80% (coverage report shows 80%+)
✅ No TypeScript errors (tsc --noEmit returns 0)
✅ Linting passes (eslint returns 0)
✅ Performance < 100ms (benchmark shows < 100ms)

❌ "Code looks good" (subjective)
❌ "Works properly" (undefined)
❌ "Well-structured" (no measurable check)

## Task: Implement User Authentication

### Phase 1: Data Layer
- Create User model with Prisma schema
- Write migration
- Run tests: `npm test -- --grep "User model"`
- Criteria: Model tests pass

### Phase 2: Service Layer
- Implement AuthService with JWT
- Add token generation/validation
- Run tests: `npm test -- --grep "AuthService"`
- Criteria: Service tests pass

### Phase 3: API Layer
- Create /auth/login endpoint
- Create /auth/register endpoint
- Run tests: `npm test -- --grep "auth API"`
- Criteria: API tests pass

### Phase 4: Integration
- End-to-end authentication flow
- Run tests: `npm test`
- Criteria: ALL tests pass

Output <promise>AUTH_COMPLETE</promise> when Phase 4 passes.

## Safety Rules

1. **Max Iterations**: Stop after 20 attempts
2. **Stuck Detection**: After 5 iterations without progress:
   - Document what's blocking
   - List attempted approaches
   - Suggest alternative strategies
3. **Critical Errors**: Stop immediately if:
   - Database corruption detected
   - Security vulnerability introduced
   - Breaking changes to existing features

# Iteration pattern
1. Read previous state (files, git log)
2. Identify remaining work
3. Implement specific change
4. Run verification suite
5. If all pass -> output completion promise
6. If failures -> analyze and continue iteration

## TDD Iteration Task

1. Write failing test for [feature]
2. Implement minimal code to pass test
3. Run `npm test`
4. If test fails -> debug and fix implementation
5. If test passes -> check if more tests needed
6. Repeat until all acceptance tests pass
7. Refactor if needed
8. Output <promise>TDD_COMPLETE</promise>

## Bug Fix Task

1. Write failing test that reproduces bug
2. Implement fix
3. Run test suite
4. If reproduction test fails -> analyze why fix didn't work
5. If other tests fail -> fix regressions
6. If all tests pass -> output <promise>BUG_FIXED</promise>

Max iterations: 10
After 5 iterations without fix:
- Document root cause analysis
- Suggest alternative approaches

## Coverage Improvement Task

Target: 80% line coverage

1. Run coverage analysis
2. Identify uncovered code paths
3. Write test for highest-impact uncovered path
4. Run tests with coverage
5. If coverage >= 80% -> output <promise>COVERAGE_ACHIEVED</promise>
6. If coverage < 80% -> continue iteration

Max iterations: 30
Progress check: If coverage doesn't improve for 3 iterations -> analyze blockers

## Performance Optimization Task

Target: Response time < 100ms

1. Run performance benchmark
2. Identify slowest operation
3. Implement optimization
4. Run benchmark again
5. If target met -> output <promise>PERF_TARGET_MET</promise>
6. If not improved -> try different approach

Max iterations: 15
Record metrics each iteration for trend analysis

# Store iteration state
npx --no-install ruflo memory store \
  --key "current-iteration" \
  --value '{"task": "auth", "iteration": 5, "lastResult": "2 tests failing"}' \
  --namespace iterations

# Search for similar past iterations
npx --no-install ruflo memory search \
  --query "auth implementation" \
  --namespace iterations

# Learn from successful completions
npx --no-install ruflo hooks post-task \
  --taskId "auth-impl" \
  --success true \
  --quality 0.9

# Initialize swarm for parallel iteration
npx --no-install ruflo swarm init --topology mesh --max-agents 5

# Spawn specialized iterators
Task("Iterate on unit tests", "Fix failing unit tests until all pass", "tester")
Task("Iterate on integration", "Fix integration tests until all pass", "tester")
Task("Iterate on performance", "Optimize until benchmarks pass", "performance-engineer")

## Task: Implement Feature X

### Success Criteria (ALL must pass):
1. `npm test` exits with code 0
2. `npm run lint` exits with code 0
3. `npm run typecheck` exits with code 0
4. No console.log statements in production code

### Phases:
1. Write failing tests
2. Implement feature
3. Fix any failures
4. Clean up and refactor

### Safety:
- Max iterations: 20
- After 10 iterations: summarize blockers
- Stop if security issues detected

### Completion:
When ALL success criteria pass, output:
<promise>FEATURE_X_COMPLETE</promise>
