Regenerate plugins/*/skills/ from plugins/*/.apm/ after the previous four commits, via scripts/sync-plugin-content.sh --all. The mirror is generated output (ADR-0017) that check-plugin-content-sync's pre-push hook diffs against .apm/; nothing here is hand-edited.

Use when managing Git submodules — the full lifecycle of a nested
|
|
repository inside a superproject — including phrasings that never say the
|
|
word, such as "add a dependency repo" or "vendor this repo inside ours".
|
|
Not multiple checkouts of one repo -> `git-worktrees`.
|
|
Not the superproject's own remotes -> `git-remotes`.

## Gotchas
|
|
|
|
- **`update` leaves the submodule in detached HEAD.** Branch inside the submodule before editing, or the work is unreachable once the pointer moves.
|
|
- **Push the submodule before the superproject.** The superproject stores only a SHA, and one missing from the submodule's remote breaks every collaborator's `update`.
|
|
- **`--recursive` is never the default.** Subcommands stop one level deep, so nested submodules go stale silently.
|
|
- **`git rm` leaves `.git/modules/<name>/` behind.** Nothing cleans it up, and it blocks re-adding a submodule there.
|
|
|
|
## Working rules
|
|
|
|
Run `rtk git` from the superproject root. Enter the submodule directory only for commits and pushes
|
|
that belong to the submodule's own history — the two repositories have independent histories, and
|
|
the same command from the wrong directory writes to the wrong one.
|
|
|
|
Before committing a superproject pointer, run `rtk git submodule status --recursive`. Prefixes: `-`
|
|
not initialized, `+` working tree differs from the recorded commit, `U` merge conflict. Add
|
|
`--cached` to read the SHAs the superproject index will record rather than the working-tree state.
|
|
A `-dirty` suffix means uncommitted changes inside the submodule, and committing the pointer over
|
|
them pins a state nobody else can reproduce.
|
|
|
|
To run one command across every submodule: `rtk git submodule foreach --recursive '<cmd>'`. Inside
|
|
`<cmd>`, Git sets `$name`, `$sm_path`, `$displaypath`, `$sha1` and `$toplevel`; append `|| :` to
|
|
continue past a failure instead of aborting the traversal. `$sm_path` and `$displaypath` name the
|
|
same directory from different vantage points — if which one you want is not obvious, read the
|
|
variable table in `references/setup-and-update.md` before writing the command.
|
|
|
|
## Dispatch
|
|
|
|
Read only the row that matches the request.
|
|
|
|
| Task | Reference |
|
|
|---|---|
|
|
| Clone a superproject with submodules; add, initialize, update or re-pin one; run a command across all of them with `foreach` | `references/setup-and-update.md` |
|
|
| Change where a submodule points — `sync`, `set-url`, `set-branch`, a local mirror override, `absorbgitdirs`, or any `.gitmodules` / `.git/config` key | `references/urls-and-config.md` |
|
|
| Remove a submodule, or `deinit` one without removing it | `references/removal.md` |
|
|
|
|
Removal and `deinit` are destructive: state what will be deleted and get confirmation before
|
|
executing.
|
|
|
|
