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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description does not contradict them. The description adds scope (free, published by TQP) but no behavioral details like pagination, ordering, or default limits. Since annotations cover the safety profile, this is acceptable but not enhanced.

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 sentence that front-loads the core action ('List free resources') and immediately mentions the optional filters. There is no redundant or tangential information, making it maximally concise.

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 simple list tool with two optional parameters and an output schema, the description covers the essential scope and filters. It does not mention pagination or default limits, but those are minor given the schema already specifies max/min values and the output schema exists. Slightly more context on ordering or result count could improve it, but it is complete enough for correct invocation.

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 100% with clear descriptions for both parameters ('Optional result limit' and 'Optional resource category slug'). The description only restates these options without adding extra meaning, so a baseline score of 3 is appropriate.

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 verb ('List') and a specific resource ('free resources published by The Quiet Protocol'), which clearly distinguishes it from sibling tools like list_kits, list_benchmarks, and get_resource. The optional filters are mentioned, making the tool's scope unambiguous.

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 description implies usage for enumerating free resources but does not explicitly state when to prefer this tool over alternatives such as get_resource or find_best_resource. No exclusions or alternative conditions are provided, leaving the agent to infer based on the 'list' verb.

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