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

The annotations clearly indicate destructiveHint=true, so the description does not need to re-state that it's destructive. The description adds no further behavioral context beyond that, such as irreversibility or side effects on related data. Given the annotation coverage, this is acceptable but could be improved by noting that deletion is permanent.

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 extremely concise (one short sentence), which is appropriate for a simple delete operation. It front-loads the action and resource. No fluff, but also no additional valuable context.

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 delete tool with one parameter accruing to a well-known resource (note), the description is arguably sufficient. However, it lacks any mention of what a 'note' is or how it is identified, and with no output schema, the agent has no info on success/failure response. Given the sibling list includes many other delete tools, a small clarification could help.

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?

The schema has 0% description coverage for the parameter 'id', and the description does not explain what 'id' refers to (probably the note's ID). The agent must infer that 'id' is the primary key of the note to delete. With no param info in the description, and schema lacking descriptions, this is a significant gap.

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 states a specific verb ('Delete') and a resource ('a note'), which clearly matches the tool's name and distinguishes it from the many sibling tools that operate on different resources (e.g., delete_application, delete_candidate). However, the description is minimal and doesn't provide additional context about what a 'note' is, but the name alone is 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 lacks any guidance on when to use this tool versus others. There is no mention of prerequisites (e.g., note must exist) or whether it can be deleted only under certain conditions. No alternatives are mentioned, but given the destructive nature, the user might need to confirm intent.

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