delete_region

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

The annotation destructiveHint: true already covers the destructive nature, so the description adds almost nothing beyond that. It does not disclose whether the operation is permanent, whether it can be undone, or what happens to the region's content. The description merely restates the action without additional behavioral context.

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, efficient sentence that front-loads the action. There is no wasted text, and it is appropriately sized for a tool with one parameter. Perfectly concise.

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 minimal schema and lack of output schema, the description should explain how to use the index (e.g., referencing get_regions to retrieve the list) and specify indexing semantics. It provides none of this, leaving an agent without enough information to call the tool correctly, especially regarding the meaning of 'index'.

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?

With schema description coverage at 0%, the description must compensate for the missing parameter documentation. It only mentions 'by index', which largely repeats the parameter name 'region_index'. It does not clarify indexing convention (0-based vs 1-based), how to obtain a valid index, or what the index refers to in the list of regions. This is insufficient for a tool with an undocumented 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 clear verb ('Delete'), resource ('region'), and identifier ('by index'). It is unambiguous about what the tool does and is distinct from siblings like delete_marker or delete_track based on the noun. However, it does not explicitly differentiate itself from other deletion tools, so it falls short of a 5.

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?

There is no guidance on when to use this tool versus alternatives such as delete_marker or delete_item. No context about prerequisites (e.g., needing to list regions first) or conditions that select it is provided. The usage is only implied by the verb and resource, which is minimal.

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