Threatmodel Analyze

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false. The description adds genuinely useful non-annotation context: this is a paid route costing 0.25 USD via x402 on eip155:8453, which matters for invocation decisions. It still discloses nothing about what the analysis produces or side effects, so it is not strong overall.

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?

Very short, but the opening sentence is a wasted restatement of the title. The payment/route sentence earns its place; the size is fine but the content mix is poor.

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?

An output schema exists, so return values need no explanation, but for a two-parameter, fully undocumented, paid, open-world security analysis tool the description is far too thin. Purpose, inputs, and when to prefer it over the adjacent security tools are all missing.

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% and both parameters (tool_manifest, deployment_context) are undocumented in the schema; tool_manifest has no type at all. The description provides zero parameter information to compensate, leaving an agent unable to know what to pass.

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 is essentially the title restated ("Threatmodel Analyze") plus an endpoint path. It never states what the tool actually does — presumably analyze a tool manifest for security threats — so an agent cannot distinguish it from siblings like v1_mcp_threatmodel_tool_permission or v1_security_dependency_risk.

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 when-to-use guidance, no prerequisites, and no mention of the closely related security siblings. The only routing signal is the HTTP path, which does not help an agent decide whether this is the right tool for a given task.

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