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

The description contradicts the annotations. It states 'Get full details' implying a read-only operation, but annotations include destructiveHint: true and readOnlyHint: false. The description provides no disclosure of side effects, permissions, or required authentication, making it misleading.

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, clear sentence that front-loads the key action and includes an informative detail about the return value. It is concise with no unnecessary words.

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?

With no output schema, the description should explain return values, which it does partially by mentioning approval addresses. However, it fails to address the annotations indicating destructive behavior, leaving critical context unexplained. The tool appears simple, but the contradiction makes it incomplete for an agent to rely on.

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 coverage is 100% with proposal_id described as 'Proposal ID'. The description merely references 'by ID' without adding additional meaning about format, source, or range. Since the schema fully covers the parameter, a baseline of 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?

The description clearly states the tool's function: retrieving full details of a governance proposal by ID, specifically including the complete list of approval addresses. This verb+resource phrasing distinguishes it from siblings like list_proposals, which lists proposals without full detail.

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 implies usage when a specific proposal ID is known and detailed information is needed, but it does not explicitly mention when not to use this tool or provide alternatives. There is no direct comparative guidance with sibling tools.

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