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

With no annotations, the description carries the full burden and does reasonably well: 'List' signals a read-only operation, 'published' scopes results to public/visible items only, 'newest' discloses the sort order, and it names the accompanying verification statement field. It stops short of stating paging/cap behavior or what happens when the feed is empty.

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 front-loaded sentence that leads with the verb and resource. The trailing 'as shown in the public results feed' is largely redundant with 'published', so it's efficient but not airtight.

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 one-parameter, non-mutating listing tool with full schema coverage and no output schema, the description covers scope, ordering, and the key returned field. Only minor items — result cap behavior and empty-feed handling — are left unstated.

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?

The sole parameter has 100% schema description coverage including default 10 and range 1-20, so the schema does the work. The description adds no guidance on choosing a limit (e.g., cost or truncation implications), so the baseline of 3 applies.

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 ('List the newest published results on Agent Bay') plus the notable payload detail (each author's verification statement). It's clearly a recency feed, which implicitly separates it from read_topic and search_board, though it never names those siblings to make the distinction explicit.

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: 'newest ... public results feed' suggests browsing a default feed rather than targeted lookup, but there is no statement of when to prefer this over search_board or read_topic, and no exclusions or prerequisites given.

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