List known Circuits components

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

Annotations already cover readOnlyHint, idempotentHint, and destructeHint, so the bar is lower. The description adds meaningful behavioral context: the catalog is local, the tool does not scrape Autodesk, and it defines the accepted vocabulary for other operations. No contradiction with 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?

The description is compact and front-loaded: first sentence states what it does, second sentence removes a likely misconception about scraping Autodesk, and the args list is brief yet informative. Every line earns its place.

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 read-only list tool with two optional parameters and a rich annotation set, the description is largely complete. It could have mentioned that omitting query returns the full catalog, but this is easily inferred from the optional filter parameter and the list semantics.

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 is 100%, so baseline is 3. The description adds value by explaining query filters by id, label, or alias, which is more specific than the schema's example filter list. The response_format mention aligns with the schema's enum and default.

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 uses a specific verb and resource: 'List the local catalog of Tinkercad Circuits parts this server knows how to search for.' It also clarifies that it does not scrape Autodesk, and identifies itself as the allowed vocabulary for two sibling tools, making it easy to distinguish from other circuit-building tools.

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?

It provides clear context by naming tinkercad_add_component and tinkercad_build_circuit as consumers of this vocabulary, so an agent can infer when to call it. It does not explicitly state 'use before adding components' or give exclusion cases, but the intended role is strongly implied.

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