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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is fully covered structurally. The description adds nothing beyond that – no pagination behavior, no note on whether the listing spans all secret managers or just the given one, no rate/limit context.

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?

One short sentence with zero padding and the action front-loaded, so there is no filler. It is arguably under-specified rather than efficiently concise, which caps it at a middling 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?

An output schema exists, so return values need not be explained, and the schema documents every parameter. Still, for a list tool in a crowded sibling set, the description omits filtering semantics, pagination expectations, and disambiguation from adjacent list tools, leaving it only minimally adequate.

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 all four parameters (limit, query, offset, secretsmanager_id) are documented in the schema, so the baseline is 3. The description contributes no additional meaning about how query matches, how limit/offset interact, or what the required secretsmanager_id scopes to.

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 specific verb and resource ("list secrets"), so the action is discernible. However, it is close to a restatement of the tool name/title and offers no differentiation from siblings like list_unified_secretsmanagers or list_unified_secretsmanager_instructions, leaving ambiguity about scope.

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 prerequisites, and no named alternatives. An agent cannot tell from the description alone whether to reach for this tool or list_unified_secretsmanagers.

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