build_request_url

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

Annotations already indicate readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is clear. The description adds no additional behavioral context beyond 'build a URL', but it does not contradict annotations. Therefore, it meets the baseline given annotation coverage.

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 a single efficient sentence with no unnecessary words. While it is very short, it earns its place by stating the core function without fluff.

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?

Despite having an output schema (not shown), the description does not mention what the tool returns (a URL). With 5 parameters and 0% schema description coverage, the description is far from complete; it lacks essential context for an agent to use parameters 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%, yet the description provides no explanation of any parameters. The schema lists 5 parameters (authority_slug, title, default_letter, body, tags) with no semantic hints, and the description fails to add meaning such as what 'prefilled' entails or how parameters map to the URL.

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 clearly states the tool builds a prefilled request URL for WhatDoTheyKnow, specifying the verb 'build' and the resource 'prefilled request URL'. However, it does not distinguish this from sibling tools like 'create_request_record' which actually creates a record, leaving room for confusion about when to use which.

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 is provided on when to use this tool versus alternatives. For example, it doesn't mention that this tool only generates a URL and does not submit a request, or that for actually creating a request one should use 'create_request_record'.

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