-      - bug: corrects wrong behavior, broken defaults, incorrect error codes,
-        retry/backoff defects, auth handling bugs, compatibility regressions.
-        Test-only changes that fix assertions for previously-wrong behavior
-        count as bug.
-      - enhancement: new API coverage, new features, new configuration
-        options, new test coverage, tooling improvements.
-        If only generated files changed with no bug claim, default to
-        enhancement.
-      - documentation: README, CONTRIBUTING, SECURITY, or other docs-only
-        changes with no runtime behavior change.
-
-      When a PR mixes categories: bug > enhancement > documentation.
-      Prefer diff evidence over the PR title.

-      You analyze CLI tool diffs for breaking changes. A breaking change is:
-      - Removal or rename of a CLI command or subcommand
-      - Removal or rename of a flag (--flag)
-      - Change in output format that would break scripts parsing the output
-      - Change in exit codes
-      - Removal of environment variable support
-
-      NOT breaking: adding new commands, adding new flags, internal refactors,
-      test changes, documentation, adding new output fields.
