# Quality Gates

This skill teaches agents how to assess task complexity, enforce quality gates, and prevent wasted work on incomplete or poorly-defined tasks.

**Key Principle:** Stop and clarify before proceeding with incomplete information. Better to ask questions than to waste cycles on the wrong solution.

---

## Overview

### Auto-Activate Triggers
- Receiving a new task assignment
- Starting a complex feature implementation
- Before allocating work in Squad mode
- When requirements seem unclear or incomplete
- After 3 failed attempts at the same task
- When blocked by dependencies

### Manual Activation
- User asks for complexity assessment
- Planning a multi-step project
- Before committing to a timeline

---

## Core Concepts

### Complexity Scoring (1-5 Scale)

| Level | Files | Lines | Time | Characteristics |
|-------|-------|-------|------|-----------------|
| 1 - Trivial | 1 | < 50 | < 30 min | No deps, no unknowns |
| 2 - Simple | 1-3 | 50-200 | 30 min - 2 hr | 0-1 deps, minimal unknowns |
| 3 - Moderate | 3-10 | 200-500 | 2-8 hr | 2-3 deps, some unknowns |
| 4 - Complex | 10-25 | 500-1500 | 8-24 hr | 4-6 deps, significant unknowns |
| 5 - Very Complex | 25+ | 1500+ | 24+ hr | 7+ deps, many unknowns |

**See:** `references/complexity-scoring.md` for detailed examples and assessment formulas.

### Blocking Thresholds

| Condition | Threshold | Action |
|-----------|-----------|--------|
| Critical Questions | > 3 unanswered | BLOCK |
| Missing Dependencies | Any blocking | BLOCK |
| Failed Attempts | >= 3 | BLOCK & ESCALATE |
| Evidence Failure | 2 fix attempts | BLOCK |
| Complexity Overflow | Level 4-5 no plan | BLOCK |

**WARNING Conditions** (proceed with caution):
- Level 3 complexity
- 1-2 unanswered questions
- 1-2 failed attempts

**See:** `references/blocking-thresholds.md` for escalation protocols and decision logic.

## Quick Reference

### Gate Decision Flow

```
1. Assess complexity (1-5)
2. Count critical questions unanswered
3. Check dependencies blocked
4. Check attempt count

if (questions > 3 || deps blocked || attempts >= 3) -> BLOCK
else if (complexity >= 4 && no plan) -> BLOCK
else if (complexity == 3 || questions 1-2) -> WARNING
else -> PASS
```

### Gate Check Template

```markdown
## Quality Gate: [Task Name]

**Complexity:** Level [1-5]
**Unanswered Critical Questions:** [Count]
**Blocked Dependencies:** [List or None]
**Failed Attempts:** [Count]

**Status:** PASS / WARNING / BLOCKED
**Can Proceed:** Yes / No
```

### Escalation Template

```markdown
## Escalation: Task Blocked

**Task:** [Description]
**Block Type:** [Critical Questions / Dependencies / Stuck / Evidence]
**Attempts:** [Count]

### What Was Tried
1. [Approach 1] - Failed: [Reason]
2. [Approach 2] - Failed: [Reason]

### Need Guidance On
- [Specific question]

**Recommendation:** [Suggested action]
```

## Integration with Context System

```javascript
// Add gate check to context
context.quality_gates = context.quality_gates || [];
context.quality_gates.push({
  task_id: taskId,
  timestamp: new Date().toISOString(),
  complexity_score: 3,
  gate_status: 'pass', // pass, warning, blocked
  critical_questions_count: 1,
  unanswered_questions: 1,
  dependencies_blocked: 0,
  attempt_count: 0,
  can_proceed: true
});
```

## Integration with Evidence System

```javascript
// Before marking task complete
const evidence = context.quality_evidence;
const hasPassingEvidence = (
  evidence?.tests?.exit_code === 0 ||
  evidence?.build?.exit_code === 0
);

if (!hasPassingEvidence) {
  return { gate_status: 'blocked', reason: 'no_passing_evidence' };
}
```

## Common Pitfalls

| Pitfall | Problem | Solution |
|---------|---------|----------|
| Skip gates for "simple" tasks | Get stuck later | Always run gate check |
| Ignore WARNING status | Undocumented assumptions cause issues | Document every assumption |
| Not tracking attempts | Waste cycles on same approach | Track every attempt, escalate at 3 |
| Proceed when BLOCKED | Build wrong solution | NEVER bypass BLOCKED gates |

---

## Version History

**v1.1.0** - Added LLM-as-judge quality validation, retry logic, graceful degradation, triple-consumer artifact design

**v1.0.0** - Initial release with complexity scoring, blocking thresholds, stuck detection, requirements checks

---

**Remember:** Quality gates prevent wasted work. Better to ask questions upfront than to build the wrong solution. When in doubt, BLOCK and escalate.

## Key Decisions

| Decision | Choice | Rationale |
|----------|--------|-----------|
| Complexity Scale | 1-5 levels | Granular enough for estimation, simple enough for quick assessment |
| Block Threshold | 3 critical questions | Prevents proceeding with too many unknowns |
| Escalation Trigger | 3 failed attempts | Balances persistence with avoiding wasted cycles |
| Level 4-5 Requirement | Plan required | Complex tasks need upfront decomposition |
