Deletes or cancels 1Claude Code: deny
  • revoke_covenantRevoke a covenant immediately and terminally.No findings

    Why it is in this group

    • The name "revoke_covenant" says "revoke": a word for removing or ending something.
    Description, as the server wrote it
    Revoke a covenant immediately and terminally. All subsequent checks deny.
Changes things 3Claude Code: ask
  • check_actCheck (and if allowed, record) a proposed act against a covenant.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.
  • grant_covenantGrant an agent a covenant: an explicit lease of authority.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.
  • verify_auditVerify the tamper-evident audit chain of allowed/denied acts.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Verify the tamper-evident audit chain of allowed/denied acts.

    Why it is in this group

    Description, as the server wrote it
    Current state, consumed/remaining budget, and check count.
  • describe_agentFleet-standard self-description.No findings

    Why it is in this group

    • The name "describe_agent" says "describe": a word for reading.
    Description, as the server wrote it
    Fleet-standard self-description.
  • list_covenantsList covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED) and/or the bound agent.No findings

    Why it is in this group

    • The name "list_covenants" says "list": a word for reading.
    Description, as the server wrote it
    List covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED) and/or the bound agent.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
