stats

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

No annotations provided, and the description only explains the output metrics. It does not disclose if the tool modifies data, requires specific permissions, or handles errors (e.g., missing file).

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?

Single sentence that conveys the tool's purpose efficiently. No wasted words.

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?

Given the lack of output schema, parameter descriptions, and annotations, the description is insufficient for an agent to reliably invoke the tool. It does not explain return format, error handling, or file path requirements.

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 input schema has 0% coverage with no parameter descriptions. The description only mentions 'bookmark file' but fails to explain what 'filePath' means, accepted formats, or constraints.

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 tool's purpose with specific verb and resources: 'Get bookmark count, folder count, and top-level distribution'. It distinguishes from siblings like 'get_stats' which might have a different scope.

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 this tool versus siblings like 'get_stats' or 'get_tree'. No context on prerequisites or alternatives.

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