PIA connects to your YouTrack instance and enriches tickets with context pulled directly from your codebase. When you type a ticket ID in JetBrains AI Assistant, PIA fetches the issue, scans relevant source files, and returns a synthesised summary including affected code areas, linked tickets, and suggested next steps. It requires three environment variables: your YouTrack URL, a YouTrack permanent token, and an Anthropic API key. PIA runs locally via uvx and never sends your code to external services — only ticket metadata and matched file paths are included in the LLM prompt.
