Use when an agent needs the shared best-copilot contract for source priority, runtime adapters, init gates, work modes, dispatch packets, review, verification, memory, spec, state persistence, or closeout.
Use inside repo-init-scan after the official stage whenever scaffold verification, bounded repair, or `best-copilot.md` rewrite is still needed.
Use when coordinating large, ambiguous, cross-module, multi-agent, planning, dispatch, fan-in, closeout, or workflow-evolution work as the Senior Project Expert.
Use when maintaining requirements, design, tasks, ADRs, execution-plan state, closeout records, or memory/spec recovery as the Specification Writer.
Use when an approved tasks.md from a Spec Bundle, or a compact approved small-work plan, should be executed by fresh-context specialist subagents, with each task receiving implementation, spec-compliance review, code-quality review, and verification before closure. DO NOT USE FOR: missing plans, brainstorming, or simple single-file edits.
Create the target repository's local spec skeleton and reusable requirements/design/tasks templates. Use from repo-init-scan during first substantial plugin use, or from spec-writing flows when `spec/INDEX.md` or `spec/templates` is missing. Do not overwrite active project specs.
