Quality Gate Calculator

Quality Gate Calculator Skill

Purpose: Calculate appropriate quality gates based on work type and phase.

When to Use: At workflow start to set expectations, and at phase transitions to validate progress.

How to Use This Skill

Executable Script: execute.sh

# Basic usage
bash .claude/skills/quality-gate-calculator/execute.sh <work-type> <phase>

# Examples:
bash .claude/skills/quality-gate-calculator/execute.sh Feature 3
bash .claude/skills/quality-gate-calculator/execute.sh Hotfix 1
bash .claude/skills/quality-gate-calculator/execute.sh Bug 4

Parameters:

• work-type: Feature|Bug|Hotfix|Documentation|Refactoring (required)
• phase: 1|2|3|4|5 (required)

Script outputs:

• Required percentage for quality gate
• Target score (points needed to pass)
• Rationale for threshold
• Pass/fail examples
• Exports quality gate to /tmp/quality-gate.env

Exit codes:

• 0: Quality gate calculated successfully
• 1: Invalid work type or phase

Quality Gate Philosophy

Not all work is equal:

• Features: Highest rigor (new functionality, high risk)
• Bug Fixes: Moderate rigor (fixing existing code)
• Hotfixes: Minimal rigor (production emergency)
• Documentation: High completion, moderate validation
• Refactoring: High quality, no behavior change

Universal Rule: ALL work types require 100% test pass rate in Phase 4.

Quality Gate Matrix

Phase 1: Requirements

Phase 2: Design

Phase 3: Implementation

Phase 4: Testing

CRITICAL: Phase 4 is ZERO TOLERANCE for all work types. One failing test = cannot advance.

Phase 5: Finalization

Usage Examples

From Orchestrator (Workflow Start)

Use the quality-gate-calculator skill to set quality gates for this feature work

Manual Calculation

# Calculate quality gate for bug fix in design phase
bash .claude/skills/quality-gate-calculator.md Bug 2

# Calculate for hotfix in implementation
bash .claude/skills/quality-gate-calculator.md Hotfix 3

From Validator

# Phase validator loads quality gate
source /tmp/quality-gate.env
echo "Required: $REQUIRED_PERCENTAGE%"
echo "Target: $TARGET_SCORE / $MAX_SCORE"

Work Type Classification Guide

Feature

Characteristics:

• Adds new functionality
• Creates new user-facing capabilities
• Introduces new APIs or components

Examples:

• "Add event registration system"
• "Implement user dashboard"
• "Create teacher profile pages"

Bug Fix

Characteristics:

• Fixes existing functionality
• Addresses reported issues
• Resolves unexpected behavior

Examples:

• "Fix login button not working"
• "Resolve event date display issue"
• "Correct user role assignment"

Hotfix

Characteristics:

• Production emergency
• Blocking critical functionality
• Requires immediate deployment

Examples:

• "Fix payment processing failure"
• "Resolve database connection timeout"
• "Patch security vulnerability"

Documentation

Characteristics:

• Creates or updates documentation
• No code changes (or minimal)
• Improves developer/user understanding

Examples:

• "Document API endpoints"
• "Create onboarding guide"
• "Update architecture diagrams"

Refactoring

Characteristics:

• Improves code quality
• No behavior changes
• Performance or maintainability focus

Examples:

• "Extract service layer"
• "Optimize database queries"
• "Simplify component structure"

Integration with Validators

Each phase validator loads work type-specific quality gates:

#!/bin/bash
# In phase-1-validator.md

# Load quality gate for this work type
source /tmp/quality-gate.env

# Use in validation
if [ "$PERCENTAGE" -ge "$REQUIRED_PERCENTAGE" ]; then
    echo "✅ PASS - Meets quality gate"
else
    echo "❌ FAIL - Below quality gate"
    echo "   Required: $REQUIRED_PERCENTAGE%"
    echo "   Actual: $PERCENTAGE%"
fi

Common Issues

Issue: Work Type Misclassification

Problem: Feature classified as bug fix to lower quality gates Impact: Lower quality work slips through Solution: Orchestrator validates work type at workflow start

Issue: Quality Gate Gaming

Problem: Developer tries to lower requirements Impact: System integrity compromised Solution: Quality gates are non-negotiable per work type

Issue: Hotfix Abuse

Problem: Everything labeled "hotfix" to skip rigor Impact: Production quality degrades Solution: Hotfix requires prod issue ticket + approval

Progressive Disclosure

Initial Context: Show work type and required percentage only On Request: Show full matrix with rationale During Validation: Show pass/fail threshold On Failure: Show how far from target and what's needed

Remember: Quality gates ensure appropriate rigor for the work being done. Features get highest scrutiny, hotfixes get pragmatic validation, but ALL work requires 100% test pass rate. This balances quality with velocity.
