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

With no annotations present, the description carries the full behavioral burden and it does disclose the most important trait: this tool produces a request but performs no execution and moves no payment, i.e. it is side-effect free. It also flags an external protocol (x402), but omits whether the returned request needs signing, auth, or a rate limit.

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 packs the purpose, the returned content, and the critical non-execution caveat with no filler. The parenthetical enumeration is dense but earns its place by naming the output components.

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 2-parameter request builder with no output schema or annotations, the description adequately covers intent and the key side-effect-free behavior, but leaves the optional contest_id parameter and any required input format undocumented, which an agent would need in order to invoke it correctly.

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% for two parameters, so the description must compensate and largely does not. 'Archived vote room' loosely maps to the required 'room' parameter, but 'contest_id' is never mentioned and no format or accepted values are given for either argument.

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 object ('Returns the exact HTTP request needed to compute standings for an archived vote room') and enumerates the payload it targets (raw and deduped tallies, per-voter breakdown). It does not explicitly differentiate itself from structurally similar siblings like archive_digest_request or tclk_audit_request, which also appear to be request builders.

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 clarifies the boundary of the tool ('does NOT run it or move any payment itself'), which implies it is used to obtain a request for later execution. However, it never states when to choose this over alternatives such as get_room_stats, nor what prerequisites or follow-up step the returned request entails.

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