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

Discloses output format (application/x-ndjson), row ordering by domain, and a verification step. However, without annotations, it does not state whether the tool is read-only, what happens with invalid dates, or rate limits. The description partially fulfills the burden.

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 brief with two sentences and a verification line. No redundancy, but the first sentence is somewhat cryptic. Information is front-loaded but could be rephrased for clarity.

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?

Missing key context: the relationship to 'snapshot_manifest' and 'snapshot_diff', what a manifest is, and how to obtain the sha256. The date parameter is unexplained, and no return type is specified (despite no output schema needed). Incomplete for a tool with one parameter.

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 description does not explain the required 'date' parameter at all. Schema coverage is 0%, and the description provides no semantics (e.g., format, range, or purpose of date). This is a critical gap.

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 indicates the tool returns bytes matching a manifest's sha256, specifying content type and ordering. However, it lacks an explicit action verb like 'retrieve' or 'get', and the purpose is not contrasted with sibling tools like 'snapshot_manifest'.

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 on when to use this tool versus alternatives such as 'snapshot_manifest' or 'snapshot_diff'. The description does not mention prerequisites or typical workflow context, leaving the agent without decision criteria.

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