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

Annotations already carry readOnly, idempotent, and non-destructive signals, so the description need not re-state them. It adds the affordable per-mint price and lighter payload comparison, but it does not disclose output shape or any rate-limit/error behavior beyond what the annotation hints provide.

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?

Three sentences are efficient and front-load the action and scope. The final sentence somewhat repeats the one-request idea already in the first sentence, which keeps it from a 5.

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 single-parameter, read-only batch tool, the description covers purpose, range, token format, pricing, and when to use it. With no output schema, it could say a bit more about what the returned scores contain, but the main context an agent needs to call it correctly is present.

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% and the schema already documents mints as Solana mint addresses in base58, 2 to 10. The description repeats the 2-10 range but adds no new param-level meaning, so baseline 3 is appropriate.

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?

Description begins with a specific verb-plus-resource: produces Watchdog scores for 2-10 Solana tokens side by side in one request. It also names get_token_snapshot as a sibling alternative, so an agent can distinguish it from similar token tools.

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?

It clearly frames the tool for screening a watchlist in one call and compares pricing to get_token_snapshot, implying when the lighter payload is preferable. It stops short of explicitly saying when not to use it or naming other alternatives, so not a full 5.

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