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

Annotations already flag destructiveHint=true and idempotentHint=false; the description adds the crucial detail that existing layout data is replaced wholesale for that language, which tells the agent what gets overwritten. It stops short of saying whether formats or languages omitted from the payload are preserved or dropped, which matters for a destructive whole-document save.

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 with no filler, and the most consequential fact (whole-document replacement) is stated up front in sentence two of a very compact definition.

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 so return values need not be described, and the core replace semantics are covered. However, for a destructive 7-parameter tool with partial schema coverage, the definition never clarifies partial-payload behavior, format coverage, or prerequisites, leaving real ambiguity.

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 57%, with language, projectId/generationId alias, and socialPrimaryFormat already explained in the schema. The description's phrase 'for one language' reinforces the language scoping but adds no format, bounds, or default semantics beyond what the schema states.

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?

States a specific verb and resource: it replaces complete social-graphics layout data for one language. The second sentence correctly frames the operation as a whole-document save rather than a field patch. It does not, however, distinguish itself from close siblings like save_graphics_format, transform_graphics, or update_graphics_settings.

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?

The 'whole-document save rather than a targeted field patch' line implies when this tool is appropriate, but there is no explicit routing to alternatives such as save_graphics_format for a single format or transform_graphics for derived versions. The agent must infer the choice from sibling names alone.

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