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

Annotations already declare readOnlyHint=true, non-destructive and non-open-world, so safety is covered. The description adds genuine behavioral value by disclosing that items in Deleted/trash return with deleted: true in metadata, a return-value trait not present in 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?

Two tight sentences, both front-loaded with the essential action and the id contract first, then the trash edge case. No filler or redundancy.

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, the description carries some return-value burden and does cover the notable deleted: true edge case for trashed reports. It doesn't describe the general item shape returned, but for a low-complexity single-param lookup the coverage is nearly complete.

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% and the single id parameter is fully documented with matching examples in the schema itself. The description's id-format examples duplicate rather than extend the schema, so baseline 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?

States a specific verb (fetch) and resource (a single item), and pins down the expected input shape with concrete id formats (report:<id> or client:<id>). This partly distinguishes it from the many get_* siblings by tying it to ids produced by search, though it doesn't explicitly contrast with get_report or get_content_brief.

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?

"by the id returned from search" implies a prerequisite workflow (search first, then fetch), which is useful implied guidance. However, it never names alternatives or states when to prefer fetch over a dedicated sibling like get_report, leaving selection to inference.

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