git_commit_no_fixup

Fail on residual fixup! / squash! / amend! commits left in scope — the ones git commit --fixup / --squash produce, meant to be collapsed by git rebase --autosquash before merging. Forgetting to rebase is the universal case; this rule catches the leftover so it doesn’t land on the main branch.

No configuration knobs — the matched subject prefixes are exactly what --autosquash understands. Shares the commit-validation family’s since: / include_merges: semantics and failure modes.

Options

Option	Type	Required	Default	Description
`include_merges`	boolean		`false`	When validating a range (`since:` set), include merge commits. Has no effect when `since:` is unset; combining `include_merges: true` with no `since:` is a load-time error.
`since`	string		`null`	Git ref to use as the base of the commit range. When set, validates every commit in `<since>..HEAD` instead of just HEAD. Accepts anything `git rev-parse` does. Use the canonical `{{env.X}}` interpolation to pass a SHA via an env var, e.g. `since: "{{env.ALINT_BASE_SHA \| default('origin/main')}}"`.

Plus the common level, id, and when fields. This rule analyses the whole repository, so it takes no paths. This table is generated from the JSON Schema; option types and defaults are authoritative.

Example

A leftover `fixup!` commit never autosquashed
