Goal

Define JarvisAPI.Diagnostics surface. Implement getDevSnapshot query, devSnapshotUpdated event, toggleDevOverlay command. Wraps DevOverlay package.

Scope

  • JarvisAPI.Diagnostics protocol
  • getDevSnapshot returns typed DevSnapshot (agent state, last 5 tool calls, context tokens, latency breakdown)
  • devSnapshotUpdated event fires per state change
  • toggleDevOverlay command (legacy hotkey or menu item)

Files

  • packages/JarvisAPI/Sources/JarvisAPI/Surfaces/Diagnostics.swift (new)
  • packages/JarvisAPI/Sources/JarvisAPI/Surfaces/Diagnostics+Adapter.swift (new)
  • packages/DevOverlay/ bridge

Acceptance

  • Protocol + adapter compile
  • getDevSnapshot() returns hydrated state
  • devSnapshotUpdated emits on state change
  • toggleDevOverlay toggles overlay visibility

Test

Scenarios S-DIAG-001..003 (DevSnapshot round-trip, stream, toggle) green in both transport modes.
