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 |
The table above is the canonical rubric. Score with max(file_count, LOC, dependency_count, unknowns), not an average: one Level 5 axis makes the task Level 5. Run scripts/assess-complexity.md or scripts/analyze-codebase.sh <target> to measure the inputs.
Blocking Thresholds
| Condition | Threshold | Action | |-----------|-----------|--------| | YAGNI Gate | Justified ratio > 2.0 | BLOCK with simpler alternatives | | YAGNI Warning | Justified ratio 1.5-2.0 | WARN with simpler alternatives | | 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
The escalation protocol and gate decision logic are both in "Quick Reference" below. The YAGNI ratio, tier LOC budgets, and simpler-alternative surfacing live in rules/yagni-gate.md.

Quick Reference
Gate Decision Flow
0. YAGNI check (runs FIRST — before any implementation planning)
→ Read project tier from scope-appropriate-architecture
→ Calculate justified_complexity = planned_LOC / tier_appropriate_LOC
→ If ratio > 2.0: BLOCK (must simplify)
→ If ratio 1.5-2.0: WARN (present simpler alternative)
→ Security patterns exempt from YAGNI gate
1. Assess complexity (1-5)
2. Count critical questions unanswered
3. Check dependencies blocked
4. Check attempt count
if (yagni_ratio > 2.0) -> BLOCK with simpler alternatives
else if (questions > 3 || deps blocked || attempts >= 3) -> BLOCK
else if (complexity >= 4 && no plan) -> BLOCK
else if (yagni_ratio > 1.5 || complexity == 3 || questions 1-2) -> WARNING
else -> PASS
Gate Check Template
## 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
## 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

**Recommendation:** [Suggested action]
Integration with Context System
// 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
// 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' };
}
Best Practices Pattern Library
Track success/failure patterns across projects to prevent repeating mistakes and proactively warn during code reviews.
| Rule | File | Key Pattern |
|------|------|-------------|
| YAGNI Gate | rules/yagni-gate.md | Pre-implementation scope check, justified complexity ratio, simpler alternatives |
| Pattern Library | rules/practices-code-standards.md | Success/failure tracking, confidence scoring, memory integration |
| Review Checklist | rules/practices-review-checklist.md | Category-based review, proactive anti-pattern detection |
Pattern Confidence Levels
| Level | Meaning | Action | |-------|---------|--------| | Strong success | 3+ projects, 100% success | Always recommend | | Mixed results | Both successes and failures | Context-dependent | | Strong anti-pattern | 3+ projects, all failed | Block with explanation |
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 |

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 |
