get_todo_list

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

Annotations already include readOnlyHint=true, so the read-only nature is covered. The description adds that the result includes items ('with its items'), which is useful context beyond the annotation, but it does not disclose details like pagination, auth requirements, or rate limits. This is consistent with the annotation.

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 short sentences: first states the action, second documents the argument. Every word earns its place with no redundancy or filler, making it appropriately concise and front-loaded.

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 simple get-by-ID tool with one parameter, an output schema, and readOnlyHint annotation, the description sufficiently covers the main purpose and parameter semantics. It could have added a note about return behavior or errors, but the existing output schema and the nature of the tool make it reasonably complete.

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 compensate. It does so by explaining that todo_list_id is 'The numeric to-do list ID', which adds meaning beyond the schema's raw integer type. However, this is still basic and does not provide additional constraints or context beyond identifying the parameter's role.

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 'Get a specific to-do list with its items' clearly states a specific action (get) on a specific resource (a to-do list) and distinguishes it from sibling tools like list_todo_lists and list_todo_items by indicating it targets a single list and includes items.

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?

Usage is implied through the phrase 'a specific to-do list' and the required todo_list_id parameter, suggesting it is for fetching one list by ID. However, there is no explicit guidance on when to use this instead of list_todo_lists or list_todo_items, and no mention of alternative tools.

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