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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds valuable context beyond that: syncFrom 'replaces their current layouts, including custom work' and 'Changes are validated before saving,' which tells the agent exactly what is lost and that validation occurs before persistence.

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, front-loaded with the core action, followed by the destructive syncFrom behavior. Every sentence carries information an agent needs, with no repetition of structured fields.

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?

An output schema exists and annotations cover the destructive profile, so return values and safety need not be restated. The description supplies the key behavioral nuance (custom work is replaced, validation before save) that an agent needs to call this mutation safely; the remaining gap, sibling differentiation, is minor for a tool this specific.

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 86%, so the schema already documents formats, language, syncFrom, and the operations structure in detail. The description mentions syncFrom behavior but adds no parameter-level detail beyond the schema, so the baseline 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 states a specific verb ('Applies layout operations') and resource scope ('selected social-graphics formats and languages'), and explains the syncFrom mode. However, it does not differentiate this tool from close siblings such as transform_layout, sync_layout, or save_graphics, leaving the agent to infer the distinction from the enum of social-graphics formats.

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, nor any named alternative. The description explains what syncFrom does but not when an agent should choose this tool over transform_layout or sync_layout, and it does not state that operations is optional when syncFrom is set.

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