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

The annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description still adds real value beyond them by disclosing a non-obvious side effect — dependent video assets are retained rather than cascaded. It does not state permission requirements or whether the deletion is recoverable, which keeps it from a 5.

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 sentences, zero preamble, with the destructive action front-loaded ahead of the retention caveat. Minor phrasing awkwardness ('will remain as it is') keeps it just short of ideal.

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 single-parameter destructive tool with an output schema and full annotation coverage, the description covers the key behavioral fact an agent needs (assets survive). It could add whether the action is reversible or what authorization is required, but it is nearly complete.

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 single `profile_id` parameter is fully documented in the schema, so baseline is 3. The description only restates that the id identifies the profile to delete, adding no format or sourcing detail beyond the schema.

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 ('removes a profile given its unique `profile_id`') and immediately scopes the blast radius by noting video assets created with the profile survive. That side-effect clause is what separates it from siblings like delete_asset or delete_source, which an agent could otherwise confuse it with.

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 explicit when-to-use or when-not-to-use guidance. The description never mentions sibling alternatives (e.g., update_profile, list_profiles) or any precondition such as confirming the profile is unused before deletion.

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