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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds the behavioral detail of pagination, which is useful but minimal. It does not describe response format, ordering, or rate limits, and it does not contradict 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 concise sentence with no filler, front-loading the key action and resource. It is appropriately sized for a simple tool, though slightly too terse to convey additional nuance.

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?

Despite having an output schema and good annotations, the description lacks essential context for selecting this tool among many similar siblings. It gives no usage guidance, no differentiation, and minimal parameter explanation. The presence of output schema reduces the need to describe return values, but the tool still feels incomplete for its search purpose.

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 0%, so the description must compensate for parameter meaning. It mentions the fuzzy hash criterion and hints at limit/offset via 'paginated', but it does not explain the format or semantics beyond what parameter names already imply. This is insufficient given the lack of schema descriptions.

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 the tool searches JS fingerprints by fuzzy hash, using a specific verb and resource. However, it does not differentiate from sibling tools like search_js_fingerprint_by_fuzzy_hash (singular) or search_by_fuzzy_hash, so it falls short of a 5.

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 on when to use this tool versus alternatives. The description only states the basic action and pagination, with no context on exclusions, prerequisites, or when a sibling tool would be more appropriate.

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