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

Annotations already declare readOnlyHint and idempotentHint as true. The description adds no behavioral traits beyond stating it is 'verified against official IRCC guidance,' which builds trust but does not contradict annotations. Adequate for a read-only informational tool.

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 two sentences, efficiently front-loaded with the core purpose ('What happens at the Canadian citizenship oath ceremony'). Every sentence adds value: first sentence lists content, second notes verification. No wasted 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?

Given no parameters, existing output schema, and annotations, the description fully covers what the tool does. It specifies scope, content, and verification source. No additional information is needed for an agent to use it 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?

No parameters are defined in the input schema (schema coverage 100% trivially). The description compensates by explaining the tool's purpose and content, providing meaning beyond the empty schema. Baseline 4 per guidelines for 0 parameters.

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 provides information about the Canadian citizenship oath ceremony, including specific topics like oath text, what to bring, and ceremony flow. It distinguishes itself from sibling tools (e.g., get_study_guide, get_test_info) by focusing on the oath ceremony.

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 explicit guidance on when to use this tool versus alternatives. The context of sibling tools and the specific topic imply usage for oath ceremony info, but no direct comparisons or exclusions are stated.

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