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

Annotations already declare readOnlyHint and idempotentHint, and the description adds meaningful behavioral context: the server never requests vulnerability notes and instructs the AI to keep them local, and the template/guidelines flow to the AI for local analysis. This goes beyond the annotations and clarifies data handling.

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 description is two sentences, front-loaded with the main purpose, and each sentence adds distinct value (template contents, privacy behavior). No fluff or redundancy.

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?

For a zero-parameter, read-only template retrieval tool, the description covers what the template includes, the privacy/security behavior, and the local-analysis flow. It is sufficiently complete without needing an output schema.

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?

The tool has zero parameters, so the schema fully covers parameter semantics. The description does not add parameter details, which is appropriate since there are none to document. Baseline 4 applies.

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 clearly states 'Get Lenny Zeltser's one-page Vulnerability Advisory Brief template' and lists the included sections, making the tool's purpose specific and distinct from sibling template tools for other domains (e.g., cti_get_template, ir_get_template).

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?

The description implies when to use the tool by specifying the vulnerability advisory context and the sections covered, but it does not explicitly name alternative tools or state 'use this instead of X.' The privacy context ('never requests your vulnerability notes... local analysis') gives additional situational clarity.

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