get_pcb_statistics

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

No annotations provided, so the description carries full burden for behavioral disclosure. It does not mention whether the tool is read-only, has side effects, or requires specific permissions. The description only states it 'gets statistics,' which is vague on behavior.

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 sentence, which is concise and to the point. No wasted words. However, it lacks structure (e.g., bullet points) but remains efficient.

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 tool has an output schema (so return format is covered), the description is still lacking context. It does not explain what kind of statistics, or how this tool differs from the many analysis tools. An agent might be unsure when to invoke this vs. specific analyzers.

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% for the single parameter 'file_path'. The description does not add meaning beyond the schema, as it just restates the path purpose. Baseline of 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 states 'Get statistics about a KiCad PCB design,' which is a specific verb and resource. It distinguishes from sibling tools that target specific analyses (e.g., analyze_pcb_nets, analyze_pcb_power_integrity) by being a general statistics retrieval tool. However, it could be more specific about what statistics are included.

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 vs. alternatives. With many analysis tools as siblings, an agent would benefit from knowing that this provides a general overview, while other tools are for detailed analysis. No when-not or alternative references.

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