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

Annotations already declare readOnlyHint=true, so only the 'pending' scoping and the shape of returned fields are added. Since there is no output schema, disclosing that each proposal carries upgrade name, target block height, and info is genuinely useful behavioral context; nothing about pagination or ordering is mentioned.

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 short sentences, purpose front-loaded, followed by return contents and a usage hook. Nothing is bloated, though the usage sentence is the weakest and does not add much beyond the purpose line.

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 parameterless read-only list tool with no output schema, the description covers scope, payload contents, and intent, which is essentially everything an agent needs to invoke it correctly. Absence of output schema slightly raises the burden, but the field list compensates.

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?

Zero parameters, so the baseline is 4; schema coverage is 100% and there is nothing for the description to clarify. No parameter-related claims are made or needed.

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 resource ('Returns all pending network upgrade proposals') and enumerates the returned fields. It is distinguishable from the singular 'get_upgrade_proposal' and 'get_upgrade_votes' siblings by the plural, list-shaped scope, though it never names them explicitly.

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?

'Use this to monitor upcoming network changes' gives an implied context but no when-not guidance and no explicit routing to the singular get_upgrade_proposal or get_upgrade_votes alternatives. Usage is inferable rather than stated.

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