B3/5.0
Behavior3/5

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

The annotations already declare readOnlyHint=true and destructiveHint=false, so the description's 'read-only' wording is largely redundant. It adds useful scope by saying assertions run against the active schematic and can traverse passive paths through common component types, but it does not explain failure behavior, result semantics, batching limits, or timeout behavior despite having no output schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no filler. It compactly conveys the core action and the passive-path scope without unnecessary repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a complex tool with five parameters, a nested oneOf schema containing seven check variants, and no output schema. A single sentence does not provide enough information about assertion type semantics, result shape, or the supporting parameters an agent may need to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 20%, so the description must carry more of the parameter meaning. It mentions pin/net checks and passive component kinds, but omits the seven assertion types, including same_node, pull_to_net, and decoupled_to_net, as well as maxHops, allPages, timeoutMs, and includeRaw.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb, 'Runs ... assertions,' and resource, 'the active schematic,' and clarifies scope with pin/net checks and passive paths. It is clear what the tool does, but it does not explicitly differentiate itself from siblings such as easyeda_trace_net, easyeda_find_unconnected_pins, 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.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit when-to-use guidance and no named alternatives. An agent can infer that this tool verifies connection assertions, but cannot tell from the description when to choose it over tracing a net, finding unconnected pins, or running ERC.

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