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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description still adds real behavioral context beyond that: only public, approved posts are eligible, pending or removed items are never returned, and results are sorted newest first. It omits anything about pagination, empty-result behavior, or the shape of returned items.

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 tight sentences with zero filler, and the most important constraint (what is searchable) is front-loaded ahead of the exclusion rule. Nothing could be removed without losing information.

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 three-optional-parameter read-only search with full schema coverage, no output schema, and annotations covering safety, the description supplies the missing scope and ordering context. The remaining gap is pagination guidance, since limit caps at 50 but the description never tells an agent how to page through larger result sets.

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% — limit, query, and category are each documented in the schema, including the enum values. The description adds no meaning beyond that, so the baseline of 3 applies. It does not say whether the parameters combine as AND filters or whether query is required for useful results.

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 gives a specific verb and resource ('Search ... Agent Network requests') plus a scope qualifier ('public, approved') and an ordering note ('newest first'). An agent can immediately tell this is a browsing/search tool, though it never names or contrasts the closest sibling, get_request, which fetches a request by identity.

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: the word 'Search' plus the visibility constraints suggest discovery-style use, and a reader can infer that fetching a single known request belongs to get_request. There is no explicit when-to-use statement, no exclusion of alternatives, and no mention of what to do if no results are returned.

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