Behavior3/5

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

Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds that it returns vote data, but does not disclose rate limits, pagination behavior, or any other side effects. With annotations covering safety, the description provides minimal additional behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that efficiently front-loads the tool's purpose, source, optional filter, and return data. Every word adds value with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core functionality and return fields with an output schema present. It lacks explicit handling of pagination (limit/offset) but is otherwise complete for a low-complexity list tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description explains the 'session' parameter's purpose ('optionally filtered by session') but does not clarify 'limit' or 'offset', which are standard pagination parameters. Given the schema has 0% description coverage, the description partially compensates for session but not for the other two.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List'), identifies the resource ('recorded votes in the Canadian Parliament'), names the data source ('OpenParliament.ca'), and describes the optional filter and return fields. This clearly distinguishes it from sibling tools like 'list_bills' or 'list_committees'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states the optional 'session' filter but does not provide guidance on when to use this tool versus alternatives (e.g., when to list votes vs. bills). No exclusions or prerequisites are mentioned.

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