delete_monthly_registration

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It does add some useful auth context by noting the API key falls back to MESS_API_KEY, but it does not disclose whether deletion is permanent, what happens if no registration exists, or any side effects. For a destructive mutation tool, this leaves important behavior under-specified.

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 compact and front-loaded with the action. The Args block is brief, every line adds meaning, and there is no repetition of schema titles or wasted phrasing.

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 thre-parameter, no-nested-object tool with an output schema, the descrition covers the core purpose and all parameter semantics. Missing caveats like irreversibility or error behavior slightly reduce completeness, but the operation is simple enough that an agent can likely invoke 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?

Schema description coverage is 0%, so the description must supply parameter meaning. It does: month is a number 1-12, year is YYYY, and api_key has an environment-variable fallback. This fully compensates for the schema's lack of descriptive text.

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 uses a specific verb and resource: 'Remove the monthly registration for a given month.' This clearly distinguishes the tool from siblings like create_monthly_registration, get_monthly_registration, and cancel_meal.

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 makes the usage context reasonably clear: this is the tool to call when removing a monthly registration. It does not explicitly name alternatives or provide when-not-to-use conditions, but the target operation is unambiguous enough that an agent can select it correctly.

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