Pulled straight from the server with tools/list on 2026-10-17.
grant_covenant

Grant an agent a covenant: an explicit lease of authority. scopes support wildcards ('payments.*', '*'); budget_minor is the total spend ceiling in minor units; expires_at is ISO-8601. Returns the covenant_id.

check_act

Check (and if allowed, record) a proposed act against a covenant. Deny-by-default. Idempotent on act_id — retries never double-consume budget. Every check lands on the audit chain.

revoke_covenant

Revoke a covenant immediately and terminally. All subsequent checks deny.

covenant_status

Current state, consumed/remaining budget, and check count.

verify_audit

Verify the tamper-evident audit chain of allowed/denied acts.

list_covenants

List covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED) and/or the bound agent.

describe_agent

Fleet-standard self-description.
