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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds 'for good', which usefully emphasizes permanent deletion beyond the generic destructive flag, though it does not describe cascading effects or whether the operation can be undone.

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, front-loaded with the action and followed immediately by the key usage constraint. No filler or redundant material.

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?

Annotations adequately cover the destructive nature of the operation, and the tool has only one required parameter. However, with no output schema and 0% schema description coverage for point_id, the description leaves the parameter underspecified and does not clarify return or side effects.

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 single required point_id parameter is never mentioned in the description. The target resource is named, so the need for an identifier is inferable, but the description adds no format, source, or usage detail for the parameter.

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 and resource ('Delete a focus point'), and the verb alone distinguishes it from siblings such as add_focus_point, update_focus_point, and list_focus. No ambiguity remains about what the tool does.

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 gives an explicit usage condition ('Only when the user clearly asks to delete it'), which is a clear when-to-use and implicitly a when-not-to-use guideline. It does not name alternative tools such as update_focus_point, but the context is clear enough for selection.

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