First release — understand pull requests instead of reading diffs

grsp opens a pull request in a read-only worktree, lets your own Claude Code or Codex explore it, and verifies everything the agent says against git before showing it to you.

Features

  • Review sessions — paste a GitHub PR URL, pick from a repo's open PRs, or compare two branches
  • Gist — "Author says" next to "Code does", a mismatch callout when they disagree, the affected entry points (including the ones the PR should have touched and didn't), comprehension questions, and a digest of the GitHub discussion
  • Ask — questions answered from the code, with an excerpt and verified file:line references
  • Walkthrough — step through the changed behaviour block by block, with "what if" inputs that re-route the path
  • Review — an AI review with your own prompt, editable findings (Blocking / Should fix / Nit), and one-click posting to GitHub with inline comments where the line is part of the diff
  • Verification layer — every code reference is checked against the worktree; change status, line numbers and excerpts come from git, never from the agent
  • Runs on your existing Claude Code or Codex subscription — no API keys
  • Per-repo review prompt in .grsp/prompt.md and analysis excludes in .grsp/config.toml
