groove-utilities-task-install

Outcome

The configured task backend is installed and verified reachable. User is informed of what was installed and how to use it.

Acceptance Criteria

• Backend CLI is available in PATH after install
• User is shown a confirmation with the installed version or a reachability check
• No-op if tasks.storage: none

Constraints

• Read tasks.storage from .groove/index.md to determine backend (if the key is still named tasks.backend from an older config, treat it as the storage value). If the key is missing or invalid, you may pause and use AskUserQuestion so the user can choose a backend (beans, linear, github, or none); then ensure .groove/index.md is updated accordingly (via /groove-admin-config or an equivalent edit) before continuing.
• If tasks.storage: none, print friendly no-op message and exit
• Installation source of truth: Do not embed OS-specific install commands in this skill. You must follow the official installation instructions from the upstream project for the user’s OS (read that page and run what it specifies). Link only:

- beans: hmans/beans — Installation section - linear: schpet/linear-cli — install section (third-party CLI; not Linear’s hosted docs) - github: GitHub CLI

• After the CLI is on PATH per those instructions, run a reachability check (beans version, linear --version / linear --help, or gh version / gh auth status as appropriate)
• If the CLI is already installed before you start, report current version and skip fetching install instructions
• If tasks.storage: beans and .beans.yml does not exist at git root:

- Run beans init to initialise the task store and generate .beans.yml with beans defaults - Derive [PROJECT_PREFIX] from the git repo name (last path component of git remote get-url origin, stripped of .git, uppercased, non-alphanumeric stripped) — e.g. groove → GRV; fall back to the directory name if no remote - Update the prefix: field in the generated .beans.yml to the derived prefix (e.g. GRV-) - Set path: in .beans.yml to .groove/tasks so the task store lives under groove (aligned with git.tasks and .groove/.gitignore). Create .groove/tasks if it does not exist. If the default .beans directory was created and is non-empty, move its contents into .groove/tasks and remove the empty .beans directory. - Report the path written and the prefix used
