WHAT IT DOES

What build_agent_context_pack does on Todos

AI agents call build_agent_context_pack to retrieve information from Todos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why build_agent_context_pack is rated Low

The tool constructs a deterministic context pack for AI agents and returns it as JSON or Markdown. It explicitly states it never calls hosted services, indicating no side effects. This is a read/query operation that assembles and returns information.

From the tool's definition 'Returns JSON or Markdown and never calls hosted services' — the tool builds and returns a context pack without modifying any data or executing external operations.

build_agent_context_pack Allowed

build_agent_context_pack is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
