List Render toolsets

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

Beyond the annotations (readOnlyHint, idempotentHint, destructiveHint), the description adds valuable behavioral context: toolsets are fixed at startup, this tool only reports the state and cannot change it. It also explains the default state (all enabled), which helps the agent understand the meaning of the output without misleading expectations.

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?

The description is concise and front-loaded: the first sentence states the core action, the second provides context, and the third clarifies the fixed nature. Every sentence adds value without redundant or verbose language.

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 simple, parameterless listing tool with strong annotations and no output schema, the description is complete. It specifies what is returned (tool count, enabled status), why it is useful, and the key constraint (fixed at startup). No critical information 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?

The tool has zero parameters, so schema description coverage is 100% and there is nothing for the description to add. The baseline for 0-parameter tools is 4, and the description correctly omits any parameter explanations.

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 the tool's action precisely: 'Lists every Render toolset with its tool count and whether it is currently enabled.' It clearly identifies the resource (Render toolsets) and the specific details returned, distinguishing it from sibling tools that list other resource types (e.g., services, deploys).

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 description explains when this tool is useful: 'discovering which Render capabilities exist, and for finding out what the operator has to change when a needed toolset is disabled.' It provides clear use cases, though it does not explicitly mention alternatives or when not to use it, which is acceptable given there are no direct sibling alternatives.

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