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

With no annotations at all, the description carries the full burden, and "Lists" only weakly signals a read-only, non-destructive operation. It does usefully disclose the returned fields, but says nothing about pagination, result caps, permission/auth requirements, or the default agent scope behavior.

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 front-loaded sentence with no filler. The trailing enumeration of returned fields is dense but each item is informative, so nothing needs to be cut.

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, and the description partially compensates by naming the returned fields. However, for a zero-annotation, zero-required-parameter listing tool it should also state result-set behavior (pagination or truncation) and confirm the default agent scope, which it leaves to the schema alone.

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%, so all four optional parameters (status, agentId, folderId, folderName) are already documented in the schema. The description only indirectly maps to them by mentioning validation status and folder assignments; it adds no filtering semantics such as how folderId and folderName interact or what ALL means in practice.

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 ("Lists all conversation flows") and enumerates what each entry carries (validation status, step counts, folder assignments, trigger types), which clearly separates it from get_flow_detail or create_flow. The one ambiguity is "flows and flow folders" – it's unclear whether folders are returned as separate items or only as assignments on flows.

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?

Usage is only implied: an agent can infer this is the discovery/browse call before drilling into get_flow_detail or mutating with update_flow/delete_flow. There is no explicit statement of when to use it, no mention of when a filtered get_flow_detail is preferable, and no exclusions.

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