mess_uncancel_registration

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

The description adds valuable behavioral context beyond annotations: it specifies the 424 error condition when the registration wasn't cancelled, and mentions the 204 success status. Annotations already cover idempotency (idempotentHint: true) and non-destructive nature, but the description provides concrete error/success details that enhance transparency.

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 perfectly structured and concise: purpose statement first, error condition second, parameter list third, return value fourth. Every sentence earns its place with zero wasted words, making it easy to parse and understand.

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 the mutation nature (readOnlyHint: false), the description covers the core purpose, error condition, and success response adequately. However, with 0% schema description coverage and no explanation of parameter semantics, there are significant gaps in understanding how to properly invoke this tool despite having an output schema.

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?

With 0% schema description coverage, the description carries full burden for parameter documentation. It only lists parameter names ('auth_key/session, meal_date, meal_type') without explaining their semantics, formats, or relationships. This minimal information doesn't adequately compensate for the complete lack of schema descriptions.

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 specific action ('Restore a previously cancelled meal registration') with the resource ('meal registration') and distinguishes it from its sibling 'mess_cancel_registration' by being the inverse operation. It's specific and unambiguous.

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 provides clear context for when to use this tool (to restore a cancelled registration) and implicitly contrasts with 'mess_cancel_registration' as the opposite action. However, it doesn't explicitly mention when NOT to use it or provide alternative tools for similar scenarios.

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