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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful content scope ('every widget... with examples'), but says nothing about size of the response, versioning, or whether the reference is static — modest added value beyond the annotations.

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?

A single front-loaded sentence that lists the covered domains after the core noun phrase. No filler, nothing that could be cut.

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 structure is not the description's responsibility, and a no-argument read-only reference is a simple tool. The only gap is the absence of any cue about when to reach for this reference relative to the other GraphMake tools.

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?

Zero parameters and 100% schema coverage, so there is nothing for the description to disambiguate. Baseline 4 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 resource — the GraphMake Script language reference — and enumerates its scope (widgets, charts, themes, styles, sizes, syntax, examples). It is unambiguous and clearly distinct from siblings like get_template or render_infographic, though it lacks an explicit verb to say whether it returns docs, a summary, or a pointer.

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 guidance on when to consult this reference versus the sibling template tools, and no statement of prerequisites or typical workflow (e.g., 'call before writing a script'). The agent must infer the use case entirely from the name and content list.

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