Usage

AI PR Insight provides three main commands: fetch, analyze, and summarize.

Fetch PR Comments

To fetch PR comments from a specific year and month within an organization:

ai-pr-insight fetch --year 2024 --month 2 --org my-org --output_file pr-comments.json

You can also filter by a specific GitHub username:

ai-pr-insight fetch --year 2024 --month 2 --username my-user --output_file pr-comments.json

Analyze PR Comments

To analyze PR comments and generate a checklist:

ai-pr-insight analyze --input_file pr-comments.json --output_dir output --batch-size 20 --model-tier premium

• batch-size: Number of comments to process in each batch.
• model-tier: Choose between economy (GPT-3.5) and premium (GPT-4).

Summarize PR Analysis Results

To consolidate and summarize analysis results:

ai-pr-insight summarize --input_dir analysis_results --output_dir summary_results --similarity-threshold 0.9 --abstraction-threshold 0.85

• similarity-threshold: Defines similarity grouping (range: 0.0 - 1.0).
• abstraction-threshold: Defines abstraction grouping (range: 0.0 - 1.0).

Enable Debug Mode

For detailed logs, add the --verbose flag:

ai-pr-insight fetch --year 2024 --month 2 --org my-org --output_file pr-comments.json --verbose

---

Configuration

AI PR Insight uses a .env file for configuration. Place this file in the root directory with the following variables:

GITHUB_TOKEN=your_github_personal_access_token
OPENAI_API_KEY=your_openai_api_key
CACHE_EXPIRATION_MINUTES=120
DEBUG=false
SOURCE_CODE_LINES_OFFSET=3

Environment Variables Explained

• GITHUB_TOKEN: Your GitHub personal access token (required).
• OPENAI_API_KEY: Your OpenAI API key (required).
• CACHE_EXPIRATION_MINUTES: Cache expiration time in minutes (default: 120).
• DEBUG: Enable debug mode (default: false).
• SOURCE_CODE_LINES_OFFSET: Number of lines to include around a code snippet (default: 3).
