Confidence Check Skill

Purpose

Prevents wrong-direction execution by assessing confidence BEFORE starting implementation.

Requirement : ≥90% confidence to proceed with implementation.

Test Results (2025-10-21):

• Precision: 1.000 (no false positives)
• Recall: 1.000 (no false negatives)
• 8/8 test cases passed

When to Use

Use this skill BEFORE implementing any task to ensure:

• No duplicate implementations exist
• Architecture compliance verified
• Official documentation reviewed
• Working OSS implementations found
• Root cause properly identified

Confidence Assessment Criteria

Calculate confidence score (0.0 - 1.0) based on 5 checks:

1. No Duplicate Implementations? (25%)

Check : Search codebase for existing functionality

# Use Grep to search for similar functions
# Use Glob to find related modules

✅ Pass if no duplicates found ❌ Fail if similar implementation exists

2. Architecture Compliance? (25%)

Check : Verify tech stack alignment

• Read CLAUDE.md, PLANNING.md
• Confirm existing patterns used
• Avoid reinventing existing solutions

✅ Pass if uses existing tech stack (e.g., Supabase, UV, pytest) ❌ Fail if introduces new dependencies unnecessarily

3. Official Documentation Verified? (20%)

Check : Review official docs before implementation

• Use Context7 MCP for official docs
• Use WebFetch for documentation URLs
• Verify API compatibility

✅ Pass if official docs reviewed ❌ Fail if relying on assumptions

4. Working OSS Implementations Referenced? (15%)

Check : Find proven implementations

• Use Tavily MCP or WebSearch
• Search GitHub for examples
• Verify working code samples

✅ Pass if OSS reference found ❌ Fail if no working examples

5. Root Cause Identified? (15%)

Check : Understand the actual problem

• Analyze error messages
• Check logs and stack traces
• Identify underlying issue

✅ Pass if root cause clear ❌ Fail if symptoms unclear

Confidence Score Calculation

Total = Check1 (25%) + Check2 (25%) + Check3 (20%) + Check4 (15%) + Check5 (15%)

If Total >= 0.90:  ✅ Proceed with implementation
If Total >= 0.70:  ⚠️  Present alternatives, ask questions
If Total < 0.70:   ❌ STOP - Request more context

Output Format

📋 Confidence Checks:
   ✅ No duplicate implementations found
   ✅ Uses existing tech stack
   ✅ Official documentation verified
   ✅ Working OSS implementation found
   ✅ Root cause identified

📊 Confidence: 1.00 (100%)
✅ High confidence - Proceeding to implementation

Implementation Details

The TypeScript implementation is available in confidence.ts for reference, containing:

• confidenceCheck(context) - Main assessment function
• Detailed check implementations
• Context interface definitions

ROI

Token Savings : Spend 100-200 tokens on confidence check to save 5,000-50,000 tokens on wrong-direction work.

Success Rate : 100% precision and recall in production testing.
