> - **Agent tool consent:** Add `"never"` to `AgentToolConsent` schema,
update imports to `lib/schemas`, surface "Never allow" in settings UI,
and prevent consent prompts/execution for tools marked `"never"`
(skipped in `buildAgentToolSet`; error if prompted).
> - **Type checks tool:** Remove settings gate so `run_type_checks` is
available by default; keep default consent `"always"`; reflected in e2e
tool list.
> - **UI/UX:** Truncate long tool descriptions to 100 chars in Agent
Tools settings.
