prx User Guide
prx is a conversation-first terminal UI for prioritizing code review. It uses AI to score each PR on how much human judgment it requires.
How It Works
- prx fetches your open PRs and scores each one on configurable risk criteria
- You see the assessment as scrollback content in a chat interface
- You interact via chat messages, slash commands, or keyboard shortcuts
- A diff overlay and bulk approve screen are available as secondary views
Scenes
- Conversation (primary): Chat + PR assessment. Type messages or slash commands.
- Diff Overlay (
ctrl+d or /diff): Full-screen diff with file/hunk navigation and inline comments.
- Bulk Approve (
/bulk): Select and approve multiple low-risk PRs at once.
Common Questions
How do I navigate between PRs?
ctrl+n next, ctrl+p previous. Or type /next and /prev.
How do I see the diff?
ctrl+d opens the diff overlay. q or esc returns to conversation. On return visits, the diff automatically shows only what's new — unchanged hunks are collapsed.
What is incremental review?
prx tracks what you've seen by snapshotting hunk and comment content hashes when you exit the diff. On your next visit (after a refresh or app restart), if anything changed, the diff opens in incremental mode: new hunks are expanded with a green "new" badge, unchanged hunks collapse, and new comments get a green badge. Edited comments get a blue "edited" badge. The scoring panel shows a green "New" summary line. Use > to expand everything back to the full diff, or {/} to jump between only the expanded (new) hunks.
How do I approve/merge/reject?
Type /approve, /merge, or /reject. Or just ask in chat: "approve this PR". All actions require confirmation.
How do I add a comment?
Type /comment to open the comment modal in the diff view. Or press c while in the diff overlay to comment on the current line.
How do I change the scoring model?
Ask in chat: "change the model to opus". Or use the set_model config tool.
How do I adjust what gets auto-approved?
Ask in chat: "set approve threshold to 2.5" or "set review threshold to 4.0". Config file: ~/.config/prx/config.toml under [thresholds].
How do I customize scoring criteria?
Ask in chat: "add a criterion for security" or "remove the novelty criterion" or "increase blast radius weight to 2.0". Criteria live in ~/.config/prx/config.toml under [[criteria]].
How do I change the merge method?
Ask in chat: "change merge method to squash". Options: merge, squash, rebase.
What do the verdicts mean?
- APPROVE: score below
approve_below (default 2.0) — safe to approve quickly
- REVIEW: between thresholds — needs normal review
- INVESTIGATE: score above
review_above (default 3.5) — needs careful attention
How do I add custom skills?
Create a directory in ~/.config/prx/skills/ with a SKILL.md file. See the reference guide for the format.
