Prune Workflows Skill

VCS Provider

This skill's safeguards use VCS operations internally (open PR detection). The orchestrate handler manages VCS provider dispatch automatically. No gh/glab/az commands needed — the MCP server handles provider dispatch.

Overview

Bulk-cancel stale non-terminal workflows that have accumulated in the pipeline. Wraps the prune_stale_workflows orchestrate action with an interactive dry-run-then-confirm UX so the user always sees the candidate set before any state mutates.

Pruning is a maintenance operation -- not a workflow phase. It produces workflow.pruned events alongside the standard workflow.cancelled events emitted by the underlying cancel path, so downstream views can distinguish user-intent cancellations from batch cleanup.
