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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered structurally. The description adds nothing about what is returned, whether it reflects live state, or any rate/scope limits, leaving the behavioral picture empty beyond the annotations.

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?

A single short sentence is appropriately sized and front-loaded, so there is no waste to trim. However, its wording is cryptic enough that brevity comes at the cost of meaning rather than in service of it.

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?

With no parameters, no output schema, and annotations covering only safety hints, the description is the sole source of information about what this tool returns — and 'switches, limits, boards and protocol paths' does not tell the agent what to expect or how to use the result. For a zero-param discovery tool, this is under-specified.

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?

The tool takes zero parameters, so there is no parameter semantics for the description to supply; baseline 4 applies. Nothing in the description contradicts or muddies an empty 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 is a noun phrase naming content areas ('switches, limits, boards and protocol paths') with no verb or stated action, so an agent cannot tell whether this retrieves config, returns metadata, or does something else. It is not purely tautological, but it is far from a specific verb+resource statement.

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 when-to-use guidance, no conditions, and no mention of any sibling tool. Among 30 action-specific siblings such as commons_boards_list and commons_whoami, there is nothing telling the agent when this catch-all 'meta' tool is the right choice over them.

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