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

With no annotations, the description carries the full burden of behavioral disclosure. It reveals the returned entry contains notes, price, and links, but it does not state that the operation is read-only, what happens when the id is not found, or any other behavioral traits. This is a partial but minimal disclosure.

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 and contains no filler, but it is a fragment ('pulsar — ...') rather than a complete instruction. It conveys some detail about the response content but omits crucial information such as the id parameter, making it under-specified rather than effectively concise.

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 simple get tool with one parameter and no output schema, the description is not complete enough. It fails to explain the input, the action, or how pulsar_get differs from pulsar_search, leaving an agent to infer the tool's purpose from its name and sibling context.

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 schema has one required string parameter 'id' with 0% description coverage, and the description never mentions this parameter or how to identify the entry. 'One entry' is too vague to tell an agent that an id must be supplied or what it represents.

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 names the resource ('pulsar') and hints at a singular result ('one entry with notes, price, and links'), but it never uses an explicit verb like 'get' or 'retrieve.' The tool name supplies the action, yet the description does not clearly distinguish this from the sibling pulsar_search.

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 guidance is provided about when to use pulsar_get versus pulsar_search or any other sibling. The description does not state that this is the right tool when an id is known, nor does it mention that search is available for querying.

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