Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, destructiveHint, and openWorldHint, so the safety profile is covered. The description adds minimal context about a 'frozen Brain Scanner policy' and 'closed scope,' which slightly clarifies but does not disclose return behavior, authorization needs, or failure semantics.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is brief, but brevity here is under-specification, not efficiency. It spends its only sentence on a generic directive and offers none of the essential details about what the tool does.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a complex oneOf schema, nested payload objects, no output schema, and sibling tools that overlap, the description is severely incomplete. An agent cannot correctly select operations, build a valid payload, or understand the result from this definition.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for the lack of parameter documentation. It mentions no parameters at all and gives no meaning to operation, payload, projectId, sessionId, or executionId. An agent gets no help understanding which operation shape to use.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description says to 'Use the closed scope read capability family,' which only restates the tool name with extra vagueness. It never states what the tool actually does, what data it returns, or that it wraps the operations get_ownership and get_pending_scope_organizations. It fails to give an agent a concrete actionable purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to invoke this tool versus the sibling tools get_ownership and get_pending_scope_organizations, nor how to choose between the two operations in the oneOf schema. The frozen-policy context is the only hint, which is not actionable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
