When work-loop plans a rename, removal, or refactor, checks that a fix reaches live code, or when bug-fix traces a bad value through its callers, it can now hand that question to repository-exploration. That skill uses a code-navigation tool your agent already has when one fits, and otherwise searches the repository.
repository-exploration now activates when a workflow or a user needs evidence to settle a pending decision, and leaves planning, building, and fixing to the workflow that asked.
