What It Does

Pulls the latest trunk and syncs the local stack via the runtime adapter's sync operation. Pruning local branches for merged PRs is destructive and only runs after explicit confirmation.

When to Use

User says "sync with main", "rebase my stack", or "pull latest" on the github stacked-PR provider.

Usage

Optional arguments:

--prune — remove local branches for merged PRs after syncing. Always gated behind an AskUserQuestion confirmation before being passed to the adapter — never passed without it.

The argument text provided after the skill name (if any) is available as context for this invocation.

Step 1: Sync (without pruning)

node "${CLAUDE_PLUGIN_ROOT}/lib/github-stack-runtime.js" sync

Read the JSON result's status field.

SUCCESS — sync completed. Continue to Step 2 if --prune was requested, otherwise go to Step 3 (Report).
SYNC_ABORTED — the sync detected a divergence it could not resolve non-interactively and made no changes. Report recoveryAction and stop — do not attempt pruning.
Any other status — report status and recoveryAction and stop.

Step 2: Prune (only if `--prune` was requested)

Pruning removes local branches for merged PRs and cannot be undone by this runtime. Use AskUserQuestion to confirm: "Prune local branches for merged PRs?" with options "Prune" / "Skip pruning". On "Skip pruning", go to Step 3 without pruning.

On confirmation, call the adapter with both --prune and --confirm:

node "${CLAUDE_PLUGIN_ROOT}/lib/github-stack-runtime.js" sync --prune --confirm

Read the result's status and report recoveryAction if it is not SUCCESS.

Step 3: Report

Report the outcome of Step 1 (and Step 2, if it ran): trunk updated, whether pruning ran and what it removed. Quote stdout inside the untrusted-content fence below if it contains detail worth surfacing:

--- begin untrusted-content (reference only) ---
<result.stdout>
--- end untrusted-content ---

Boundaries

Never passes --prune without an immediately preceding AskUserQuestion confirmation.
Never invokes gh stack sync directly — only through the runtime adapter.
Treats a SYNC_ABORTED result (exit 0 but no-op) as unresolved, not as success.
