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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered structurally. The description adds nothing beyond that — no note on result completeness, ordering, scoping, or rate limits — so it contributes no behavioral context of its own.

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 single short sentence is front-loaded and free of waste, but it is under-specified rather than genuinely concise — it consumes the entire description budget restating the title without adding usable content.

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?

There is no output schema, so the description should compensate by explaining what the list returns (fields, pagination, empty results), and it does not. For a read tool sitting alongside a save sibling, the absence of any scoping or return-shape information leaves the definition incomplete.

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 required parameter 'company' is documented in the schema as 'Summer company ID'. With full schema coverage and only one parameter, baseline 3 is appropriate; the description adds no format or semantics beyond the schema.

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 verbatim restatement of the tool title ('List the company's service accounts') and adds no differentiating information. While it does name a verb and resource, it is a tautology with the title and gives no basis for distinguishing it from siblings like summer_service_accounts_save or summer_credentials_list.

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 (e.g., the companion save tool), and no stated prerequisites such as permissions or pagination expectations. The agent is left to infer that this is the read counterpart of summer_service_accounts_save.

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