Compare schematic and PCB

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

Annotations already declare this as read-only, non-destructive, and closed-world, so the safety profile is covered. The description adds useful analysis scope by listing the discrepancy categories and a synchronicity score, but it does not disclose operational behavior such as whether both targets must already be open or how the comparison is scoped.

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 tightly written sentences, front-loaded with the cross-domain comparison purpose and followed by a compact list of detected discrepancies. Every phrase contributes to identifying the tool's scope.

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?

There is no output schema, and the description lists detected issue types plus a synchronicity score but does not explain the result structure or whether omitted targets default to active documents. For a three-parameter nested-target analysis tool, it covers purpose well but leaves important operational and return-value details thin.

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 coverage is 67%: pcbTarget and schematicTarget already carry 'Expected PCB/schematic document target' descriptions, and timeoutMs is self-documented with default and bounds. The description reinforces the two-domain mapping with 'between Schematic and PCB' but adds no target-selection or timeout semantics 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 states a specific action and resource: cross-domain discrepancy analysis between Schematic and PCB in EasyEDA Pro. It then names concrete discrepancy types it detects, which clearly distinguishes it from single-domain siblings such as easyeda_run_drc or easyeda_run_schematic_erc.

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 cross-domain framing and issue list imply this is the tool for schematic-vs-PCB consistency checks, but it never explicitly says when to use it instead of easyeda_prepare_schematic_pcb_sync, easyeda_verify_connections, or single-domain validation tools. Usage is inferable rather than directly stated.

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