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

Description discloses required scopes (email:write) and explicitly says 'Mutating: changes server state, which adds behavioral info beyond the annotations readOnlyHint=false. However, it does not describe side effects, idempotency behavior, or the nature of whitelisted entries. No contradiction with annotations.

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 compact and front-loaded with the action, then provides essential metadata (HTTP method, category, scopes, mutating flag) on separate lines. Every line carries information and nothing is fluffed.

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 mutating tool with an open, undeclared body schema and no output schema, the description is insufficient. It gives no indication of what the request body should contain, what a whitelist entry looks like, or what response/outcome to expect. An agent would likely be unable to invoke it correctly without external documentation.

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 input schema has 100% coverage for the body parameter, so the baseline is 3. The description adds no further parameter meaning: it does not describe expected body fields, formats, or examples. The schema itself only says 'Schema not statically declared — see API docs, leaving the agent without usable payload guidance.

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?

Description clearly states the action 'Add to whitelist' with the HTTP endpoint POST /v1/spam/whitelist, which distinguishes it from sibling spam tools like get/delete whitelist and add blacklist. It is a specific verb+resource, though it does not explain what a whitelist entry consists of.

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?

No when-to-use vs alternatives is provided. The description does not mention when adding to whitelist is preferable over blacklist, nor does it reference any related tool such as panelica_spam_post_v1_spam_blacklist or delete whitelist. Selection would depend only on the tool name and endpoint.

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