AI Impact Assessment for Code Changes

CheckodAI

AI Impact Assessment for code changes - understand what Copilot changed before you commit it.

Overview

CheckodAI is a Python CLI tool that helps developers understand the scope and implications of their code changes by analyzing git diffs and extracting modified symbols (functions, classes, variables). It can optionally use a local LLM (Ollama) to assess the risk of each change.

Privacy

CheckodAI runs entirely locally.

• No code is uploaded
• No cloud calls required
• No telemetry
• Works offline with local LLM (Ollama)

All analysis happens on your machine.

Key Features:

• 🚀 Local-first: Runs entirely on your machine - no cloud calls
• 🔍 Symbol-level analysis: Detects changed functions, classes, and variables
• 🏷️ Change type detection: Identifies what type of change (added, removed, modified, signature changed)
• 💡 Impact summaries: Human-readable recommendations for each changed symbol
• 🤖 AI-powered risk assessment: Uses local Ollama for intelligent impact analysis
• 🛡️ Commit guard: Advisory warnings for HIGH risk changes (non-blocking)
• 🎯 CLI-first interface: Simple checkod assess command
• 📊 Summary reports: Clear output of what changed and risk levels
• ⚡ Graceful fallback: Works without Ollama using heuristic analysis

Installation

Prerequisites

• Python 3.8+
• Git
• Ollama (optional, for AI risk assessment)

Initial Setup

Install from PyPI:

pip install checkod-ai

How to Use

1. Make your code change (or let Copilot make changes)

2. Stage your changes with git

git add .
# For new files, you may need:
git add -N .

3. Run the assessment (no AI)

checkod assess

Or, to use AI-powered risk assessment (requires Ollama):

checkod assess-ai

Note: For newly created files, you must run git add -N . (intent-to-add) so that checkod assess or checkod assess-ai can detect them. This is a git limitation for diff tools.

Usage

Basic Commands

Analyze changes in the current repository:

checkod assess

Analyze a specific repository:

checkod assess --repo /path/to/repo

Example Output

🔍 Starting Impact Assessment...

📊 Changed Symbols (3 detected):
  • calculateDiscount
  • OrderStatus
  • userTier

📈 Change Summary:
  Functions: 1 function added
  Classes: 1 class added
  Variables: 1 variable added

================================================================================
📋 Impact Summary
================================================================================
You changed: calculateDiscount()
Change Type: function added
Risk Level: MEDIUM

This may affect:
  • checkout_service (logic flow)
  • /api/orders (user-facing behavior)
  • test_checkout (test coverage)

Recommended Actions:
  • Write unit tests for calculateDiscount
  • Test integration with checkout service
  • Document function parameters and return type

Optional: Install Ollama for AI Risk Assessment

Ollama enables intelligent risk scoring. Install and configure:

# macOS / Linux
curl -fsSL https://ollama.ai/install.sh | sh

# Or use Homebrew (macOS)
brew install ollama

# Pull the model
ollama pull llama3

# Start the server (runs on localhost:11434)
ollama serve

With Ollama running, you'll also get AI-powered risk assessment:

================================================================================
🤖 AI Risk Assessment (powered by local Ollama)
================================================================================
Symbol: calculateDiscount
────────────────────────────────
Risk Classification: MEDIUM

Reason: Used in multiple modules; requires testing and code review.

Validation Steps:
• Test discount calculation across pricing tiers
• Verify integration with checkout service
• Add regression tests if coverage is low

How It Works

1. Reads git diff - Gets all staged and unstaged changes
2. Extracts symbols - Finds functions, classes, and variables
3. Detects change type - Identifies what kind of change was made
4. Assesses risk - Uses local AI (Ollama) or heuristics
5. Generates recommendations - Suggests testing and review actions
6. Advisory warnings - HIGH risk changes trigger warnings
