add_task

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

No annotations are provided, so the description must carry the full burden. It states 'Add a new task' but does not disclose permissions, idempotency, duplicate handling, or effects on existing tasks; the output schema exists but is not described in the text. This is a mutation tool with minimal behavioral disclosure.

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 a single sentence with no filler, and the key verb/resource are front-loaded. It is appropriately brief for a simple tool, though it could include more context without becoming verbose.

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 trivial complexity and presence of an output schema, the description covers the basic purpose. However, with no annotations and no usage guidance, it leaves gaps around behavior and choice among sibling tools; it is minimally adequate.

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%, and the description adds no meaning beyond the schema's 'task' string titled 'Task'. It does not explain expected format, length, or whether the task string includes status/priority; the single parameter's semantics are only obvious from its name.

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 ('Add') and resource ('task'), clearly indicating the operation on the todo list. This differentiates it from siblings (complete_task, delete_task, list_tasks) by naming the create action.

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 guidance is given about when to use this tool over alternatives; siblings are listed but no exclusions or context are mentioned. The description only states the action, leaving the agent to infer usage from the tool name.

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