vs_indexes_delete

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

The description is consistent with annotations (destructiveHint: true), but adds no additional behavioral context beyond the word 'Delete'. It does not disclose consequences like irreversibility or required permissions, though annotations already indicate destructiveness.

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 sentence stating the purpose plus a REST endpoint, front-loaded with the action. Every character earns its place with no redundancy.

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 operation with one parameter and annotations covering destructiveness, the description adequately covers the basic purpose. However, it could be improved by mentioning that the action is irreversible or that the index must exist, but overall it is sufficient given the low complexity.

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 coverage is 100% and the parameter description 'Fully-qualified index name' is provided. The tool description adds no further semantics for the parameter, so baseline score of 3 is 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?

The description clearly states "Delete a Vector Search index" which specifies the verb and resource, distinguishing it from sibling tools like vs_indexes_create or vs_indexes_get. The inclusion of the REST API endpoint adds further precision.

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 usage guidance is provided beyond the purpose. There is no mention of when to use this tool versus alternatives, such as when to delete an index instead of syncing or querying it, nor any prerequisites or conditions.

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