Execute Linear Epic

Execute the child issues of a Linear epic with one fresh implementation subagent per task and integrate them through an aggregation branch.

Input

epic is required. Accept a Linear issue ID, project name, URL, or other unambiguous identifier. Stop and ask when it is missing or ambiguous.

Resolve context

1. Fetch the epic and its child issues through the Linear MCP or other available integration. Record identifiers, descriptions, acceptance criteria, statuses, priorities, dependencies, and links.
2. Inspect the repository before changing it: current branch, worktree status, remote, default branch, local instructions, contribution docs, package scripts, and CI checks.
3. Preserve unrelated local changes. Update the remote default branch without rewriting local work.
4. Create or resume an aggregation branch using repository conventions; fall back to epic/<epic-slug>.
5. Order unfinished tasks by dependency, then priority, then identifier. Skip only tasks proven complete or already integrated.
