gh-plan-issues

Turn a triaged milestone of issues into an execution plan: coherent workstream clusters by shared subsystem/files, with approach, dependencies, build order, and a lead train. Planning only — never merge, close, comment, or tag from this skill. Decide from code+tests+comments+checks, never from title alone.

When to use

• A milestone (e.g. v0.8.62) has a triaged but unsequenced issue list and you need workstreams, ownership boundaries, and a build order.
• You must separate epics from landable-now and expose hidden coupling before contributors start parallel work.
• Run after 03-community-inbox-steward triage; before 04-integration-train.
