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

With no annotations provided, the description carries full burden. It only says 'list all... with optional filtering', lacking details on whether the operation is read-only, how the 'limit' parameter affects results, or what the return format is. There is a subtle inconsistency: 'list all' suggests unbounded results, but the 'limit' parameter contradicts this.

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 a single concise sentence of 8 words, front-loaded with the key action and resource. No unnecessary words or repetition.

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 listing tool, the description covers the basic purpose. However, it lacks return format details and does not explain the behavior of the 'limit' parameter (e.g., pagination or truncation). The absence of output schema increases the need for such info, which 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?

Schema description coverage is 100%, so each parameter already has a description. The tool description adds only 'optional filtering', which does not enhance meaning beyond what the schema provides. 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 'List all available ReactBits components with optional filtering' clearly specifies the action (list), the resource (ReactBits components), and the optional filtering capability. This distinguishes it from siblings like 'get_component' (details), 'list_categories' (categories only), and 'search_components' (text search).

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 states 'optional filtering' but does not explicitly guide when to use this tool versus alternatives like 'search_components'. It implies listing all or by category/style, but no exclusion criteria or context for choosing are provided.

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