get_handwriting_status

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

With no annotations, the description carries the full behavioral burden. It discloses non-rendering behavior, lightweight operation, and the specific status fields checked. It doesn't discuss side effects or return format, but 'Check' implies a read-only operation.

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 two sentences with the purpose and key constraints front-loaded before usage triggers. Every fragment ('Lightweight', 'Does NOT render an image') adds decision-relevant information without redundancy.

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 zero-parameter read-only status tool, the description covers what it returns (status fields), what it avoids (rendering), and when to invoke it. No output schema exists, but listing the status fields is sufficient guidance for correct usage.

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 zero parameters, so the schema is vacuously 100% covered. No parameter-specific description is needed, and the baseline for zero-parameter tools is 4.

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?

States a specific verb ('Check') and resource ('tablet status') and enumerates the exact status fields: stroke count, revision, connected tablets, new-content flag. It also explicitly distinguishes itself from image-rendering tools with 'Does NOT render an image.'

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?

Gives explicit trigger phrases '有更新吗' and '有没有新内容' for when to call. The negative behavior 'Does NOT render an image' and 'Lightweight' help an agent choose it over image-producing alternatives, though no sibling tool is named directly.

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