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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description's remaining content (pagination, returned fields) largely restates the input schema and the output schema rather than adding new behavioral context such as rate limits or result-size caveats.

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?

A single front-loaded sentence with no filler; the pagination clause and the return-field clause both earn their place without padding.

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?

An output schema exists, so return values need not be spelled out, and the annotations cover the safety profile. The description adequately conveys pagination and lookup key, though it omits any note about empty results or how this differs from the singular sibling.

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, and it only partially does. It explicitly names limit and offset for pagination and implies hash_value ('with this SHA-1'), but gives no defaults, ranges, or format details for any of the three parameters.

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?

States a specific verb and resource: retrieving archived script fingerprints matching a given SHA-1, with clear scope ('with this SHA-1'). It reads clearly, but does not differentiate itself from the near-identical sibling search_js_fingerprint_by_sha1 (singular) or the other hash-variant searchers (by_md5, by_sha256), leaving the agent to guess which of the pair applies.

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?

There is no when-to-use, when-not-to-use, or alternatives guidance at all. The purpose implies lookup by SHA-1, but nothing steers the agent between this tool and the many sibling hash/pattern searchers listed.

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