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

No annotations are provided, so the description carries the full burden and fails it. It does not say whether deletion is irreversible, whether contained files are removed, what permissions are required, or what happens when the named store does not exist.

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 single sentence is front-loaded with the verb and free of filler, so nothing is wasteful. However, brevity here reflects under-specification rather than economy, leaving the definition too thin to act on.

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 destructive mutation with no annotations, no output schema, and an undocumented parameter, the description omits everything an agent needs: irreversibility, side effects on contained data, and error semantics. It is inadequate for the tool's risk profile.

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%, so the single required parameter "name" is entirely undocumented in structured data. The description only implies name refers to a store identifier; it gives no format, case sensitivity, or whether it must already exist.

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 gives a specific verb and resource ("Delete a store"), but "store" is never defined and no distinction is drawn from the closely-named sibling storage_file_delete. An agent can guess the gist but cannot tell whether a store is a namespace, a bucket, or a file collection.

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 when-to-use, when-not-to-use, or alternative routing guidance. The presence of storage_file_delete and storage_list in the sibling list makes the missing distinction (deleting an entire store vs. one file) a real ambiguity the description does nothing to resolve.

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