list_discussions

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

With no annotations provided, the description carries the behavioral burden. It does disclose that results are paginated and how to navigate pages, which is useful, but it doesn't clarify ordering, the shape of returned items, or what happens when interest_id is omitted. The phrase 'within an interest area' could even be read as implying interest_id is mandatory while the schema marks it optional.

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 the core action and scope first and pagination details second. There is no filler or redundant prose.

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?

For a simple paginated list tool the basics are covered, but there is no output schema to define the returned discussion items, and the relationship between the optional interest_id and the phrase 'within an interest area' is left ambiguous. This leaves an agent without full information for a correct call under all conditions.

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 the parameters are already individually documented. The description only restates the default limit and offset usage rather than adding new semantics; it adds no detail about interest_id 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 names a specific verb and resource ('List discussions') and adds a scoping phrase ('within an interest area'), which helps distinguish it from read_discussion/create_discussion/delete_discussion. It doesn't explicitly contrast with search_posts or browse_interests, so it falls just short of full sibling differentiation.

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?

It gives clear context for the list action and explicit pagination guidance: default page size is 20 and offset is used for subsequent pages. It does not name alternatives or state when not to use this tool, so it lacks exclusionary guidance.

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