Rich connection diagnostics for the Figma bridge (never a bare boolean): plugin connection, leader/follower mode, port, heartbeat, queue, sessions, and an ordered list of concrete next-step hints when something is off.

Read the Figma canvas with a token-frugal response. Choose an operation and pass its params. layout_audit is the structured verify tool (declared vs rendered bounds, overflow, clipping, truncation). read_selection deep-reads the current selection in one call — the entry point of the selection-first edit-in-place lifecycle (read_selection → figma_write modify → layout_audit).

Execute modern-ES JavaScript in a sandbox against the figma.* proxy to draw/modify the canvas. state persists across calls in a session. Banned: require/process/fetch/timers/eval. Returns { ok, result, logs, warnings }.

One-call design-system rule sheet as markdown: styles + variables + components, fetched in parallel. Read before drawing so you reuse tokens/components instead of hardcoding.
