My biggest issue is the difference of behavior with the other commands (with the check of arguments). I would prefer to forward them verbatim for now.
If we really want to do some check, it makes sense to do that globally (for example, --dry-run will probably be a mess for commit too).
Here is what Claude said:
Code
1. git_commit.rs:62 — extend opts before --amend --no-edit --allow-empty, not after. This is already the placement commit_opts/commit_captured use (git commit -S -m x), so it's the deviation, not a new rule. Last-wins then neutralises --no-amend, --edit, --fixup, --squash, -F, -c/-C.
2. Delete reject_content_args (fold.rs:202) and its four call sites.
3. Keep no_git_args, committed_onto, undo_commit_attempt and the tree/parent guards — emptiness-only and state-only, both already allowed by the convention. They cover what's left: no commit at all, amend-instead-of-commit, amend-did-nothing.
4. git_commit.rs:102 — drop the private rev_parse, call super::rev_parse.
5. fold.rs:1772 — skip the reset_soft when HEAD still equals head_oid, so a plain failed hook can't produce the "could not put your commit back" warning.
6. Soften the tree-guard message so it doesn't assert the -- argument was the cause (a reformatting pre-commit hook trips it).
Docs/specs
7. specs/021-git-args.md — drop "fold is the one exception"; rewrite Fold Commits Too around ordering + state guards; fix the placement example to git commit -n --amend --no-edit --allow-empty; and replace "a rebase runs no commit hook" with a plain "not covered yet" for absorb/split/reword.
8. fold.md / specs/007-fold.md — replace the three rejected classes with the honest gaps: a forwarded -m rewords the amend, a pathspec restricts it, and --dry-run/--amend are caught after the fact and rolled back.
Tests
9. Drop the two reject_content_args unit tests; add coverage that -- --amend on the fixup path and -- --dry-run roll back with history intact. The integration cases keep their shape — assert rollback instead of "cannot forward".

That's not entirely true. At least split would benefit, as it's creating a new commit. Pretty sure others could benefit too (Claude said absorb and reword)... I've added a task to review the other in #291

fold makes a commit of its own — the amend, or the `fixup!` commit for a non-HEAD target — and that one runs the user's commit hooks, which there was no way to skip. It now takes the same `--` separator as commit and add. A form that only rebases rejects the separator, having no commit to forward to. Everything else reaches git verbatim, as on the other commands; loom's own arguments go last, so a boolean git resolves last-wins keeps the value loom asked for. The rest is the user's business, except a commit that never happened: `--dry-run` and the status formats make git print and exit 0, so both commit paths check what git did and take the attempt back before anything is rewritten.

In `@specs/021-git-args.md`:
- Around line 132-138: Update the fold semantics in the sections covering
--fixup and --squash in specs/021-git-args.md and specs/007-fold.md: distinguish
intermediate fixup!, amend!, and squash! commit messages from the final
autosquashed target message, including that plain --fixup discards its message,
--fixup=amend:/reword: replaces the target message, and --squash combines
messages. Apply these distinctions consistently to direct folds and folds moving
files or hunks between commits, without claiming these options reword every
created commit.
In `@tests/integration/test_fold.sh`:
- Line 1085: Update the expected text passed to assert_contains in the
fold_rebase_only_msg assertion to include the literal backticks emitted by
no_git_args: match “runs no `git commit`” exactly.

I don't know if you want to fix or comment the last AI comments. Thank you for the changes, looks good,
I'm confused. Which comment is still open? |

fold makes a commit of its own — the amend, or the
fixup!commit for anon-HEAD target — and that one runs the user's commit hooks, which there was
no way to skip. It now takes the same
--separator as commit and add.A form that only rebases rejects the separator, and so does an argument that
changes what the commit holds or says, or that skips the commit: fold rewrites
on top of that commit, and would otherwise amend or squash the wrong one. A
blocklist only stops what it knows, so both commands also check what git
actually did before anything is rewritten.
