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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false; the description adds meaningful behavioral context by stating that no assessment target is contacted, which is a valuable safety guarantee beyond the annotations. It also clarifies the records are 'cleared' public records, adding scope information not present in the schema or 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 a single, well-structured sentence that front-loads the action and resource, then packs the search dimensions and safety constraint into the remainder. Every clause contributes useful information with no wasted words.

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 read-only search tool with no output schema, the description is nearly complete: it covers the searchable parameters, the publication status filter, and the no-target-contact guarantee. A small gap is that it does not mention paging behavior or default counts, though limit has a default documented in the schema. Overall, an agent can safely and correctly invoke it based on this description plus annotations.

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 100%, with query and limit already documented in the input schema. The description largely restates the query semantics (search by CVE identifier, project name, publication status), and the schema already says 'Text to match against CVE identifiers, project names, and publication status.' Thus the description adds limited new meaning beyond the structured schema.

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 begins with a specific verb ('Search') and clearly identifies the resource ('cleared public Hacker Bob CVE records') plus the search dimensions (CVE identifier, open-source project name, publication status). This distinguishes it from sibling tools like get_public_cve_record and list_public_cve_records, which imply fetching or enumerating rather than searching.

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 specifies the searchable fields and the behavioral constraint of 'without contacting any assessment target,' providing clear context for when the tool is appropriate. However, it does not explicitly state when to prefer this tool over the sibling get_public_cve_record or list_public_cve_records, so it stops short of naming alternatives or exclusions.

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