List every team in the Linear workspace. Returns each team's identifier (key), human-readable name, and UUID. Use this first when you don't know a team's key.

List cycles (sprints) for a team. Cycles have per-team monotonic numbers (HYD-cycle-2 is different from another-team-cycle-2). Filter by scope to narrow to only past, current, or future cycles.

List issues in a Linear cycle. Provide EITHER cycle_id (from list_cycles) OR both team and cycle_number. Returns identifier, title, state, assignee, priority, estimate — enough to render a cycle overview.

Fetch full details for one Linear issue. Accepts either the human identifier (e.g. 'HYD-123') or the internal UUID. Returns description, state, assignee, cycle, labels, and the most recent comments.

Search the workspace's issues by text. Matches title, description, and comments. Returns identifier, title, state, URL — shape aligned with list_issues_in_cycle so results can be treated the same way.
