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

No annotations exist, so the description carries the full burden, but for a zero-parameter read it has little to disclose. It does add genuine behavioral context by scoping results to the current user, yet says nothing about result ordering, pagination, or what a returned report entry looks like — and no output schema covers that 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?

A single sentence with no filler, and the scoping constraint is front-loaded. Nothing could be trimmed without losing information.

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 zero-param list tool the description is nearly sufficient, but with no annotations and no output schema the agent still cannot know the shape or fields of the returned report entries (id, name, type), nor whether results are paginated. A short clause on return contents would close the gap.

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 no parameters (0 params, empty schema), so there is nothing for the description to clarify. Baseline 4 applies; no parameter meaning is missing or misstated.

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?

States a specific verb and resource ('List all online reports') with a scope qualifier ('available to the current user'), so the operation is unambiguous. However, it offers no differentiation from siblings that also enumerate resources (list_documents, list_names, list_library) or from the report-specific get_report_data/delete_report, so an agent must infer the boundary itself.

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 and no alternatives named. Nothing tells the agent whether this is a discovery step before get_report_data, how it relates to list_documents, or whether there are prerequisites. Usage is only weakly implied by the 'list' verb.

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