clear_sketch

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

No annotations are present, so the description carries full burden. It states 'Clear the drawing canvas' implying destructive behavior, but lacks details on reversibility, confirmation prompts, or what happens to existing content beyond being cleared.

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 concise sentence that directly states the action and purpose. Every word earns its place; no extraneous information.

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?

The description is adequate for a simple, zero-parameter action. However, it does not explain the result (e.g., success feedback, return value) or any side effects. With no output schema, slightly more context about what the user can expect after clearing would improve completeness.

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?

There are no parameters (0), and schema coverage is 100%. The description adds no parameter information, but none is needed. Baseline 3 applies for high coverage, but given zero parameters, a 4 is warranted as no additional meaning is required.

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 clearly states the verb 'Clear' and the resource 'drawing canvas', indicating a specific action. It distinguishes from sibling 'get_sketch' which retrieves data. However, it does not explicitly differentiate the tool's purpose from alternatives.

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 use or not use this tool. There is no mention of prerequisites, alternatives, or scenarios where this tool should be avoided. Only a single sibling exists but no comparison is provided.

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