C2.2/5.0
Behavior3/5

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

Annotations already declare this is a non-read-only, open-world, non-idempotent but non-destructive operation. The description adds useful payment and route context, but it does not explain what the threat model does with the manifest, what side effects occur, or what auth/payment flow is required beyond the price line.

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

Conciseness3/5

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

The description is short and front-loads the route and price, but its opening sentence merely repeats the title. It is concise only because substantive information is missing rather than because it is efficiently structured.

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

Completeness2/5

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

Even accounting for the available annotations and output schema, the description does not state what the tool produces, how to use its parameters, or when to select it over related tools. It is not complete enough for reliable selection or invocation.

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

Parameters1/5

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

Schema description coverage is 0%, and the description says nothing about the two parameters 'manifest' and 'ownership_proof'. With zero parameter meaning supplied by either the schema or the description, an agent cannot infer the expected format or role of these inputs.

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

Purpose2/5

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

The description largely restates the title, 'Tool Permission Threatmodel,' without explaining what the tool actually does. The remote route adds an endpoint but not a functional purpose, and there is no differentiation from siblings such as v1_security_threatmodel.

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

Usage Guidelines2/5

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

There is no guidance on when to use this tool, when not to use it, or how it differs from related threat-modeling or security siblings. The endpoint and price are stated, but usage conditions are absent.

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