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

Annotations already carry the safety profile (destructiveHint=true, readOnlyHint=false), so the description only needed to add context beyond that. It does so by disclosing the key behavioral outcome: after removal the client 'falls back to the agency branding,' telling the agent the slot is not left blank. No contradiction with the destructive annotation, though it stops short of disclosing reversibility.

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 short sentences, front-loaded with the action and followed by the consequence; every word earns its place. There is no redundant restatement of the title or parameter list.

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 action, the essentials are covered: id comes from the schema, destructiveness from annotations, the removal target and fallback from the description, and return values from the output schema. Minor gaps remain around prerequisites and whether the logo can later be restored via update_client, but nothing needed to invoke the tool correctly 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 for the single parameter is 100% ('Client ID (from list_clients)'), so the schema already documents id fully. The description's 'client's' wording merely reinforces the schema's existing meaning and adds no format, source, or syntax detail. Baseline 3 applies per the high-coverage rule.

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 specifies a concrete action ('Remove a client's full logo') and identifies the exact field being removed, '(logo_url)'. The 'client's' scope and 'full logo' wording implicitly differentiate it from the sibling favicon and account-logo removal tools, though it never names a sibling explicitly.

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 when-to-use or when-not-to-use guidance is provided. Sibling tools like remove_account_logo, remove_client_favicon, and remove_account_favicon clearly overlap in purpose, yet none are mentioned to disambiguate selection. The fallback note describes a consequence, not a routing condition.

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