SKILL.md

Verify information accuracy against codebase and docs

Verifies if a statement is true by checking your project's code and documentation.

Usage

bash
# Basic usage
/check-fact "The Flutter app uses Riverpod"
# Check multiple facts at once
/check-fact "This project uses GraphQL and manages routing with auto_route"
# Check technical details
/check-fact "JWT is used for authentication, and Firebase Auth is not used"

How It Works

  1. Where I Look (in order)
  • The actual code (most trustworthy)
  • README.md and docs/ folder
  • Config files (package.json, pubspec.yaml, etc.)
  • Issues and PR discussions
  1. What You'll See
  • ✅ Correct - Statement matches the code exactly
  • ❌ Incorrect - Statement is wrong
  • ⚠️ Partially correct - Some parts are right, some aren't
  • ❓ Cannot determine - Not enough info to check
  1. Proof I Provide
  • File name and line number
  • Relevant code snippets
  • Matching documentation

## Fact Check Results
### What You Asked
"[Your statement]"
### Verdict
[✅/❌/⚠️/❓] [True/False/Partial/Unknown]
### Evidence
- **File**: `path/to/file.dart:123`
- **Code**: [The actual code]
- **Note**: [Why this proves it]

[If unknown, here's what I'd need to check]

Basic Examples

bash
# Check the tech stack
/check-fact "This app is built with Flutter + Riverpod + GraphQL"
# Check if a feature exists
/check-fact "Dark mode is implemented and can be switched from user settings"
# Check architecture choices
/check-fact "All state management is done with Riverpod, BLoC is not used"
# Check security setup
/check-fact "Authentication tokens are encrypted and stored in secure storage"

Collaboration with Claude

bash
# Check dependencies
ls -la && find . -name "pubspec.yaml" -exec cat {} \;
/check-fact "The main dependencies used in this project are..."
# Check how something is built
grep -r "authentication" . --include="*.dart"
/check-fact "Authentication is custom built, not using third-party auth"
# Check if docs match reality
cat README.md
/check-fact "Everything in the README is actually implemented"

When to Use This

  • Writing specs: Make sure your descriptions are accurate
  • Taking over a project: Check if you understand it correctly
  • Client updates: Verify what's actually built
  • Blog posts: Fact-check your technical content
  • Presentations: Confirm project details before presenting

Important

  • Code beats docs: If they disagree, the code is right
  • Old docs happen: Implementation is what matters
  • No guessing: If I can't verify it, I'll say so
  • Security matters: Extra careful with security-related facts

Security
