react-router

Create and package React Router pull requests. Use when the user asks to create, open, prepare, or finish a PR for this repository, including branch/commit/push handoff, draft PR creation, PR body writing, and applying GitHub labels such as pkg:*, feat:*, docs, github-actions, or dependencies.

Bring a blocked React Router community pull request across the finish line. Use when the user invokes `/finish-line` or `$finish-line`, provides a PR number or URL, and asks Codex to resolve merge blockers such as an unsigned CLA, missing change file, missing documentation, or stale contributor follow-up. Handles deciding whether to push small maintainer fixes onto the contributor PR branch or recreate the PR from main under a maintainer branch when the contributor's CLA is not signed.

Fix a reported bug in React Router from a GitHub issue. Use when the user provides a GitHub issue URL and asks to fix a bug, investigate an issue, or reproduce a problem. Handles the full workflow: fetching the issue, finding the reproduction, writing a failing test, and implementing the fix.

Implement a React Router RFC from a GitHub discussion URL. Fetches the proposal, evaluates community feedback, resolves outstanding questions interactively, then implements the feature with tests, future flags (if breaking), and a changeset.

Prepare React Router release notes before running the changes/versioning scripts. Use when asked to review, polish, normalize, or prepare pending change files under packages/*/.changes, remove semantic commit prefixes from release bullets, enforce imperative tense, decide whether a manual scripts/changes/whats-changed.md section is warranted, or draft long-form release notes for new features, stable future flags, or unstable flags.

Build applications with React Router in Framework, Data, Declarative, and unstable RSC modes. Use when configuring routes, route modules, loaders, actions, forms, fetchers, navigation, pending UI, SSR/SPA/pre-rendering, middleware, URL params/search params, or React Router upgrades.
