## Tools
- lakera_guard_create_policy(name: string, detectors?: object[], default_threshold: string, custom_guardrail_ids?: string[]) — Create an Enterprise Lakera policy with built-in detectors and/or custom guardrails. Lakera may omit the new policy ID; if omitted, later retrieval, replacement, and deletion require external policy l
- lakera_guard_create_project(name: string, action?: string, policy_id?: string, project_metadata?: object) — Create an Enterprise Lakera project, optionally assigning a policy, metadata, and detect-or-flag action. Omit policy_id to use the default policy. Lakera does not return the generated project ID, so l
- lakera_guard_delete_policy(policy_id: string) — Permanently delete an Enterprise Lakera policy by ID. The provider rejects deletion while any project is assigned to the policy.
- lakera_guard_delete_project(project_id: string) — Permanently and irreversibly delete an Enterprise Lakera project by ID. Historical requests lose their association with the project's metadata and assigned policy.
- lakera_guard_evaluate_detectors(dev_info?: boolean, messages: object[], metadata?: object, project_id?: string) — Evaluate content and return one confidence result per configured detector without producing an aggregate flagging decision or Guard screening log. Use for analysis and tuning, not runtime allow/block 
- lakera_guard_get_policy(policy_id: string) — Retrieve an Enterprise Lakera policy by ID, including its detector configuration, custom guardrails, version, and assigned projects.
- lakera_guard_get_project(project_id: string) — Retrieve an Enterprise Lakera project by ID, including its assigned policy, metadata, and detect-or-flag action.
- lakera_guard_screen_content(payload?: boolean, dev_info?: boolean, messages: object[], metadata?: object, breakdown?: boolean, project_id?: string) — Screen the latest LLM or agent interaction with Lakera Guard and return the policy decision. Use this for runtime allow/block decisions; earlier messages provide context, but only the latest interacti
- lakera_guard_update_policy(name: string, detectors?: object[], policy_id: string, default_threshold: string, custom_guardrail_ids?: string[]) — Replace an Enterprise Lakera policy's complete configuration and create a new policy version. Omitted detectors or custom guardrails are removed, so retrieve the policy first when preserving existing 
- lakera_guard_update_project(name: string, action?: string, policy_id?: string, project_id: string, project_metadata?: object) — Update an Enterprise Lakera project by ID. Name is required by the official request schema; retrieve the project first when preserving its current name or other optional settings.
