B3.3/5.0
Behavior3/5

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

readOnlyHint=true already signals a safe read, and the description adds that content is PLECS's own help text surfaced through system.methodHelp. It does not say what happens for an unknown or non-RPC method name, nor whether an empty string can be returned — gaps that matter for a passthrough lookup.

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?

One sentence, front-loaded with the verb and resource, with zero filler and the upstream RPC name folded in parenthetically. Nothing is wasted.

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

Completeness3/5

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

An output schema exists, so return values needn't be explained, and the read-only annotations cover the safety profile. However, the sole parameter is undocumented and the unknown-method behavior is unstated, leaving the definition minimal for correct invocation.

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?

The single parameter has 0% schema description coverage, so the description must carry the burden, and it only says "method" without stating the expected format (e.g., dotted name like model.get) or how to obtain a valid value. The neighboring plecs_list_methods tool hints at it, but nothing in this definition confirms it.

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?

States a specific verb and resource ("Return PLECS's own help text for an RPC method") and even names the underlying call, system.methodHelp, so the agent knows this is documentation lookup, not method invocation. It does not explicitly contrast with plecs_list_methods or plecs_rpc, leaving sibling differentiation to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

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

The purpose implies you call this to read docs before using an RPC method, but there is no explicit when-to-use or when-not-to-use guidance and no mention of plecs_list_methods as the way to discover method names. Usage is implied rather than stated.

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