pcb_analyze_via

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'Analyze via electrical characteristics.' This reveals nothing about whether the operation is read-only, what outputs are produced, how calculations are performed, or any limitations. It is essentially a rephrasing of the tool name.

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 only four words, which is extremely concise but also under-specified. For a tool with six required parameters, this brevity is underspecification rather than effective conciseness.

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 tool has six required parameters, no output schema, and no annotations, yet the description provides only a vague statement about analyzing via electrical characteristics. It fails to explain what the tool computes, what the inputs mean, or what the user can expect as a result. This is grossly inadequate for an AI agent to select and invoke the tool correctly.

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 0%, so the description must compensate for the six undocumented parameters. It does not explain any parameter names, units, or how they relate to the analysis. The parameter names are self-explanatory, but the description adds no semantic value beyond the schema.

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 analyzes via electrical characteristics, distinguishing it from sibling tools like pcb_calc_via_stitching or pcb_analyze_current_loop. However, it does not specify which electrical characteristics (e.g., impedance, capacitance) are computed, making the scope somewhat broad.

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 is provided on when to use this tool versus alternatives. It lacks any mention of prerequisites, use cases, or comparisons with other analysis tools.

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