Get Jlcpcb Database Stats

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering the safety profile. The description adds the 'local' qualifier, clarifying that it accesses the local database rather than a remote service, but otherwise does not elaborate on behavior or output specifics.

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 sentence, front-loaded with the verb and resource, with no wasted words. It exactly states the purpose without any redundant explanation.

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?

This is a simple, side-effect-free stats query with no parameters and an output schema to define returns. The description, combined with strong annotations and the output schema, provides everything an agent needs to decide to invoke it.

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 tool accepts zero parameters, so schema coverage is trivially 100%. Per the baseline for 0-parameter tools, the description doesn't need to document parameter semantics, and it correctly avoids adding any.

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 the specific verb 'Get' and identifies the resource as 'statistics about the local JLCPCB parts database', clearly distinguishing it from sibling tools like search_jlcpcb_parts and get_jlcpcb_part. The 'local' qualifier adds needed 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?

The description implies usage when an agent needs statistics about the local JLCPCB parts database, but it does not explicitly state when to prefer this over alternatives such as download_jlcpcb_database or search_jlcpcb_parts. No exclusions or alternative references are given, leaving the agent to infer the appropriate context.

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