panelica_spam_post_v1_spam_blacklist

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

Annotations are absent, so the description bears full responsibility for behavioral transparency. It only indicates a POST operation (creation) but fails to disclose what the request body should contain, whether the operation is idempotent, or what happens upon success/failure. The behavior is under-specified.

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 very short, but it lacks critical details. The inclusion of HTTP method and category adds little value. Important information about input or behavior is missing, making it not appropriately sized for the tool's complexity.

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 the tool has no annotations, no output schema, and the input schema is empty, the description is severely incomplete. It fails to explain how to perform the addition or what the expected response is. The agent cannot correctly invoke this tool based solely on the provided description.

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 zero parameters with 100% schema coverage (empty). Despite no parameters, the description does not clarify how the blacklist entry is specified (e.g., via query string, request body, or URL). A baseline of 4 for zero parameters is not warranted because the description omits essential input information.

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 states 'Add to blacklist', which is a clear verb+resource. However, it does not specify what is being added (e.g., email address, IP, domain), leaving ambiguity. The tool name and HTTP method imply a POST to the blacklist endpoint, but the exact entity is unclear.

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 usage guidelines are provided. The description does not indicate when to use this tool versus alternatives like panelica_spam_post_v1_spam_whitelist or panelica_spam_delete_v1_spam_blacklist_id. There is no context for differentiation.

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