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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive/closed-world behavior, so the safety profile is covered. The description adds a useful visibility constraint ('only data visible to the linked Market Brew account'), but says nothing about scoping to the required askWidgetId or about return format.

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 short sentences with no filler, and the usage trigger is front-loaded ahead of the account-visibility note. Efficient, even if under-specified.

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 carry more of the return-shape burden; it only hints at visibility scope and never explains what a conversation listing contains. With a required widget id and a nested filter object, an agent is left with open questions.

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 only 50%: the 'query' filter object is documented in the schema, but the required askWidgetId is not described anywhere. The description contributes no parameter meaning at all, so it fails to compensate for the coverage gap.

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 'list Ask conversations,' which is a clear verb+resource but essentially restates the tool name and title. It offers no differentiation from close siblings such as count_ask_widget_conversations or get_ask_conversation, so an agent must infer the distinction.

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?

'Use this when the user asks to list Ask conversations' gives an implied trigger condition, but there is no guidance on when to prefer this over the count_ or get_ siblings, and no stated prerequisites or exclusions.

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