Scope Guard tools (6, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

create_scope_contractwrite action
Define an agent's scope boundaries: allowed/forbidden tools, file access paths, and delegation limits.
detect_delegation_loop
Check a delegation chain for circular patterns. Detects when agents delegate back to each other creating infinite loops.
detect_work_duplication
Find agents doing the same work. Compares action logs across all agents — if 2+ agents called the same tool with similar arguments, flags as potential duplication.
get_compliance_report
Get a compliance summary for all agents: total actions, scope violations, delegation counts, and scope utilization percentage.
log_agent_action
Track what an agent is doing. Logs tool calls, delegations, file accesses, and completions for compliance monitoring and duplication detection.
validate_action
Check if a proposed action (tool call, file access) is within an agent's scope contract. Call this BEFORE the agent executes.
