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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds two pieces of context the annotations cannot: the cascading deletion of replies when the note starts a thread, and the authorization requirement (author or presentation owner).

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?

Two short sentences, no filler, with the core action and its cascade effect front-loaded before the permission clause. Every clause earns its place.

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?

With annotations covering the mutation/destructive profile, an output schema present, and the parameter fully documented, the description supplies the remaining critical facts: cascade deletion and who is authorized. Only the distinction from resolve_comment is left implicit.

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 100% for the single comment_id parameter, so the schema fully documents the input. The description adds no format, syntax, or lookup guidance beyond what the schema provides, making the baseline 3 appropriate.

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?

States a specific verb and resource ('Delete a note') and clarifies the cascade scope ('with its replies, when it starts a thread'). It is clearly distinguishable from add_comment/list_comments, though it does not explicitly contrast with resolve_comment, which is the nearest ambiguous sibling.

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?

Provides a permission condition ('Its author or the owner of the presentation may do it') but gives no explicit when-to-use guidance versus alternatives such as resolve_comment (which likely closes rather than removes a comment). Usage is only implied.

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