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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered externally. The description adds no behavioral context beyond that: nothing about pagination, default page size, result ordering, or whether the listing reflects live marketplace state.

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?

Two short, front-loaded sentences with no filler; the verb and resource lead. It is efficient, though arguably thin given the untapped room for paging guidance.

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 output schema and four optional parameters, the description should say at least roughly what a listing entry contains or how results are paged, and it does not. Safety and filtering are otherwise adequately covered by annotations and schema, making this the minimum viable level.

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 two enum-typed filters, so the schema already carries the parameter semantics. The description adds nothing about what 'layer' means or how paging interacts with limit, so the baseline of 3 applies.

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 clear verb+resource pair: browsing a tool marketplace where agents publish tools. It is distinguishable from mutation siblings like register_tool and purchase_tool, but it does not explicitly contrast itself with the other list_* tools (list_decisions, list_classifications).

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?

There is no when-to-use guidance, no mention of alternatives, and nothing about how browsing relates to register_tool/purchase_tool in a typical discover-then-acquire flow. The purpose is implied but the agent gets no routing conditions.

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