Trace EasyEDA Pro component connections

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description usefully discloses what the response contains (pins, nets, adjacent components, confidence ratings), which matters because there is no output schema. It says nothing about scope/behavior of allPages, timeout handling, or the oddly non-idempotent hint.

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?

One compact sentence with the resource list front-loaded and zero filler. It is appropriately sized, though the enumerated list could have been paired with a scoping clause without adding much length.

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?

For a 4-parameter tool with no output schema, the description covers the return contents reasonably well but leaves three parameters entirely unexplained and offers no routing guidance among very similar siblings. It is minimally adequate rather than complete.

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 only 25% — only 'query' is documented. The description adds no meaning for allPages, timeoutMs, or includeRaw, all of which are undocumented in both schema and description. With low coverage the description should compensate, and it does not.

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?

States a specific verb ('Traces') and enumerates the resources returned: component pins, connected nets, adjacent components, and confidence ratings. This clearly identifies a component-centric connectivity trace. However, it never distinguishes itself from the closely related siblings easyeda_trace_net and easyeda_get_component_pins, so the agent must infer the boundary.

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?

'for schematic debugging' is the only context given, which is a general theme rather than a when-to-use rule. There is no guidance on when to pick this over easyeda_trace_net (net-centric) or easyeda_get_component_pins (pins only), and no prerequisites or exclusions are stated.

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