Type Alias: ToolTier

ToolTier = "session" | "agent" | "shared"

Defined in: packages/agentos/src/emergent/types.ts:35

Lifecycle scope tier for an emergent tool.

Tools progress through tiers as they prove reliability. Higher tiers require more stringent promotion verdicts and multi-reviewer sign-off.

• 'session' — Exists only for the current agent session; discarded on shutdown.
• 'agent' — Persisted for the agent that created it; not shared globally.
• 'shared' — Promoted to a shared tool registry; available to all agents.
