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

Annotations already declare destructiveHint=true, but the description adds genuinely useful context beyond that: the word 'Permanently' conveys irreversibility and the raw REST endpoint (DELETE /files/{uuid}/) is disclosed. It still omits permissions/auth requirements and what happens if the file is already deleted.

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?

Three terse sentences, with the operation and its destructive nature front-loaded before the implementation detail. Every clause earns its place and nothing is padded.

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 one-parameter destructive tool with no output schema, the description covers the essentials: what is deleted, that it is permanent, and the underlying API call. Minor gaps remain around auth/permissions and idempotency on repeated deletes, but nothing critical is missing.

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% with a single required uuid parameter that is already documented in the schema ('File UUID to delete.'). The description adds no format, source, or constraint detail beyond what the schema provides, so the baseline 3 applies.

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 names a specific verb (deletes) and resource (a file from the project) and qualifies it with 'Permanently', making the operation unambiguous and clearly distinct from siblings like uploadcare_get_file and uploadcare_store_file.

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?

Usage is implied rather than stated: 'Permanently deletes' plus 'Destructive' signals caution, but there is no explicit when-to-use guidance, no mention of the alternative uploadcare_store_file, and no note on prerequisites or recovery.

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