PRfait

/pɹ̩.feɪ/ — a quadruple pun across two languages. It's PR fait (French: "PR done"), parfait (French: "perfect", English: the dessert), and sounds like PR fate — because every pull request deserves to meet its destiny, not languish in review limbo.

A terminal UI for reviewing pull requests with semantic diff analysis.

PRfait fetches open PRs from configured GitHub repositories, runs semantic analysis (via inspect-core and sem) to identify meaningful entity-level changes, and presents them in a TUI with structural diffs, risk scoring, and inline review comments.

Features

• Semantic diffs — diffs are grouped by entity (function, type, module) rather than raw line changes, powered by tree-sitter
• Risk scoring — entities are ranked by risk score incorporating blast radius, dependency count, public API surface, and change classification
• Cross-PR overlap detection — when the same entity is modified in multiple open PRs, it's flagged as a merge conflict risk and boosted in sort order
• Inline review comments — write review comments directly in the TUI, with multi-line drag selection and GitHub suggestion blocks
• Side-by-side and unified diff modes — toggle with d
• External editor integration — press e to open a file in your editor; edits are converted to GitHub suggestion comments automatically
• Reviewed file tracking — mark files as reviewed with x; state persists across sessions
