Contribute to Superset

Take the user from "I want to fix/build X in Superset" to a merge-ready PR that follows the repo's rules. If the checked-out repo has CONTRIBUTING.md, DEVELOPMENT.md, or AGENTS.md, those files are authoritative; read them and prefer them over this summary.

1. Scope first

• Bug fixes, docs, small improvements: straight to a PR, no issue needed
• New features or larger changes: open an issue first at https://github.com/superset-sh/superset/issues/new/choose to agree on the approach before building
• Questions: Superset Discord, not an issue

2. Set up

1. gh auth status, then fork and clone: gh repo fork superset-sh/superset --clone (or add a fork remote to an existing clone)
2. Best experience: add the clone as a project in the Superset app and create a workspace per change, so contributions develop inside managed worktrees
3. In the new workspace/worktree, run ./.superset/setup.local.sh once (configures per-workspace ports, app identity, local services, and a seeded dev account; no external credentials needed), then bun run dev
4. Bun only, never npm/yarn/pnpm. Read the root AGENTS.md and follow it.

3. Make it merge-ready

• Branch from main; one change per PR, so unrelated finds become a second PR
• Before pushing: bun run lint:fix, then verify bun run lint exits clean (CI fails on warnings too), bun run typecheck, bun run test
• PR title must be a conventional commit (feat(desktop): ..., fix(web): ...); PRs are squash-merged with the title as the commit subject
• Include proof it works: screenshots or recordings for anything user-visible, before/after for fixes. The dev desktop app exposes CDP for clean captures; see "Capturing screenshots via CDP" in CONTRIBUTING.md
• Check "Allow edits from maintainers" and link the issue for non-trivial changes

4. Open it

gh pr create against superset-sh/superset main, fill in the PR template honestly (what you ran, what you clicked, what's covered by tests), and report the PR URL back to the user.
