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

No annotations are present, so the description must disclose behavior. It specifies the scope ('public object') and ordering ('newest occurrence first'), but does not mention side effects, pagination, or any constraints. The lack of a read-only hint or other safety information is a gap.

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?

The description is extremely short, but it is a sentence fragment rather than a complete sentence. It is under-specified, so while concise, it sacrifices clarity. It earns a partial score.

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?

Given no annotations and no output schema, the description must fully explain the tool's behavior. It only provides the output scope and sort order, leaving ambiguity about 'occurrence', pagination, and relationship to other tools. This is insufficient.

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 has zero parameters, so the schema is empty. The description adds meaning by indicating the output scope, which is sufficient for this dimension. Baseline of 4 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 is a noun phrase describing the output ('Every public object') rather than an explicit action. It conveys the tool's scope and sort order but does not clearly state what the tool does (e.g., 'List' or 'Get'). It somewhat distinguishes from siblings by implying a global list, but this is not explicit.

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 guidance is provided about when to use this tool versus alternatives like list_collection or search_collection. There is no mention of use cases or exclusions, leaving the agent to guess the tool's intended role.

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