The commit handler ran `git add <paths>` followed by `git commit`
without a pathspec, so anything pre-staged externally before the
handler ran was swept into the commit. #2767 fixed every call site
to use --files but left the handler emitting a pathspec-less commit,
so the bug survived the well-formed form too.
Compute pathsToCommit once and pass `'--', ...pathsToCommit` to every
git commit invocation: regular, --amend, and commit-to-subrepo. The
staged-files check uses the same pathspec so "nothing staged" reflects
what would actually be committed, not unrelated index entries.
Two follow-up safeguards on the same surface:
* When `--files` is passed but every following token gets filtered out
(e.g. `--files --no-verify`), reject with `--files requires at least
one path` instead of silently falling back to .planning/.
* Both `git add` invocations now use the `--` separator so a path
starting with `-` (e.g. a file literally named `-A.md`) is treated
as a pathspec rather than a git option.
Adds five regression tests in `commit.test.ts`: three covering the
pathspec scope (`--files`, `.planning/` fallback, and `--amend` with
pre-staged unrelated changes), one covering the empty `--files`
rejection, and one covering the `-A.md` round-trip.
Closes#3061
scripts/fix-slash-commands.cjs SEARCH_DIRS did not cover agents/, sdk/src/,
or top-level files, so 9 colon-form references survived in 6 files. The hit
at agents/gsd-codebase-mapper.md:105 propagated into ~/.claude/agents/ at
install time (the fixer is not wired into install) and produced unrunnable
/gsd:<cmd> suggestions in agent output on non-Gemini runtimes.
This commit includes Pass 1 (the 9 line edits) AND Pass 2 (extending the
fixer's SEARCH_DIRS so future regressions are auto-rewritten and caught by
the bug-2543 guard, which mirrors that list). The standalone bug-3100 test
added in the prior revision is removed in favor of the bug-2543 guard's
extended scan, per CONTRIBUTING.md test standards (no source-grep tests on
non-.md files).
