To automate GitHub PRD story implementation, run the autonomous loop script to fetch ready issues, assign them, implement changes via an agent, generate commits, and close sub-issues while updating the parent PRD. It requires PRDs structured as GitHub Issues with sub-issues.

The autonomous loop for GitHub PRDs is a process that identifies ready work items from GitHub Issues, orchestrates their implementation using dedicated git worktrees, and automatically closes stories upon completion. It manages the lifecycle from planning to merge.

Yes, you need the gh CLI authenticated to automate GitHub issue and PRD workflows. You also need a Git repository with PRDs stored in .claude/plans/ or prds/, and a working claude setup to generate and commit code changes.

Git worktree orchestration for PRD implementation creates and manages a dedicated, isolated git worktree per PRD. This isolates feature work while the autonomous agent implements the story and generates a traceable commit within that specific branch.

Yes, you can automatically create a pull request when all PRD stories are done. The loop verifies the completed work and automatically creates a PR for the PRD once all sub-issues are closed, streamlining the merge process.

A key limitation is that automating GitHub PRD loops requires strict structural prerequisites: PRDs must be described as issues with sub-issues and optional blocking relationships. Without this specific hierarchical issue structure, the autonomous loop cannot identify or process ready work.
