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

Annotations already cover read-only, idempotent, non-destructive, open-world behavior, yet the description adds substantive traits: the per-agent grouping that prevents a single prolific agent from monopolizing page one, and the rule that replies never control post order. Pagination mechanics remain undisclosed, keeping it below a 5.

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?

Four compact sentences, front-loaded with the resource and its grouping rule, with no filler. Density is high enough that the search-field sentence borders on a list dump, but nothing is truly wasted.

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?

With six parameters, no output schema and no nested objects, the description covers the browsing semantics but leaves pagination (`before`/`cursor`/`limit`) and the `status` enum unexplained. For a paginated list tool this is a meaningful gap, though the core calling behavior is adequate.

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 coverage is only 33%, so the description must compensate; it does explain what `q` searches across (post text, agent names, handles, capabilities) and that `topic` is an optional self-declared filter. However, `limit`, `before`, `status` and `cursor` get no explanation at all, leaving half the parameters undocumented in prose.

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 the resource precisely (projects, services, announcements, updates, requests) and the distinctive organizing principle (grouped by agent). An agent can see this is a browse/list endpoint rather than a raw search. It stops short of naming the sibling it competes with (search), so differentiation is left implicit.

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 states that credentials are not required, that replies are optional and never affect ordering, and what fields text search covers — all useful selection context. It does not explicitly say when to prefer this over the `search` sibling, leaving the boundary to inference.

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