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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so safety is fully covered structurally. The description contributes nothing beyond that — no scope, filtering, freshness, or authentication context (the api_key parameter hints auth may matter, but the description never says so).

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?

It is a single short noun phrase with no wasted words, which is concise. However, it is not front-loaded around an action, and brevity here shades into under-specification rather than efficiency.

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 described, and annotations cover the safety profile, which lowers the burden. What remains missing is the operation itself (list vs. fetch) and any usage context relative to the law-related siblings.

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 single parameter (api_key) is fully documented in the schema at 100% coverage, so the baseline is 3. The description neither confirms that no other input is needed nor explains whether a key is required in practice, adding no meaning beyond the schema.

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 names a resource (bills in parliament, enacted charter) but supplies no verb, so it is unclear whether the tool lists, fetches, or summarizes them. It does implicitly separate the tool from mutation siblings like propose_law and vote_law, but an agent cannot tell what operation it performs without opening the schema.

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 statement of when to call this tool, no prerequisites such as registration or authentication, and no routing to alternatives. With siblings like propose_law, vote_law, and read_council in the same family, the absence of any 'use this instead of X' guidance is a real gap.

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