Changesets

Changesets describe user-visible behavior for release notes. Root AGENTS.md defines when automated contributions require one; CONTRIBUTING.md is canonical for package selection, versioning, branch targets, and prose format.

Decide Whether One Is Required

A changeset is required for behavior visible to users of the CLI, libraries, published crates, diagnostics, parser, formatter, linter, or assists.

No changeset is needed for an internal refactor with identical behavior, tests only, CI/build maintenance, or documentation-only edits.

Before opening a PR, explicitly confirm the user-facing classification as required by AGENTS.md. Do not infer user visibility only from the files changed.
