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

Annotations already declare readOnlyHint=true and openWorldHint=false, and the description is fully consistent with a safe read. Beyond that it discloses the non-obvious behavioral traits: the data is a pre-synthesized snapshot rather than live data (with query_sentiment named as the live alternative), and that quote ids are indirect references requiring a second resolution call.

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?

Front-loaded with the core definition before the routing guidance, and each sentence carries actionable information. The 'fastest way to get a high-level picture of player sentiment' line mildly restates the pre-synthesized framing, a small redundancy in an otherwise tight definition.

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 carries the return-value burden and does so thoroughly by naming every returned field group and the quote-id indirection. Combined with the sibling routing and skill preloading instruction, nothing an agent needs to invoke and interpret this tool is missing.

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% and both parameters (projectId, environment) are documented in the schema itself, including the list_projects discovery hint. The description adds no additional meaning about scoping, defaults, or environment semantics, so it sits at the baseline for a fully documented two-parameter 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?

States a specific verb and resource ('Get the latest Community Pulse snapshot') and immediately defines it as 'the pre-synthesized topic rollup the dashboard's Community Pulse page shows', which anchors it to a concrete artifact. It also enumerates the payload (volume, sentiment split, trend, insight clusters, quote ids), so an agent can distinguish it from query_sentiment without opening either schema.

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?

Explicitly routes between this tool and the sibling: use this for a high-level picture, use query_sentiment for live data, drill-downs, or custom time windows. It even names the exact follow-up call syntax (query_sentiment({ operation: 'quotes', contentIds })) for resolving quote ids, and recommends loading the understand-community-pulse skill first.

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