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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine context beyond that: the topic root is included for topic targets, each message carries a replyAction tied to its feedback id, replies are optional, and community content is separated from the KG.

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 tight sentences, front-loaded with the core purpose before the response-shape and cost details. No filler, though the sentence about replyAction is arguably a return-value detail that the output schema already covers.

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?

An output schema exists, so return values need not be spelled out, and the description still covers target scoping, the optional-reply behavior, and the community-vs-KG boundary. It is complete enough to call correctly, with pagination already handled by the schema's limit/offset descriptions.

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 schema already documents every parameter including the standalone-comment default for targetId/targetType. The description restates the entity/topic/section scoping and the topic-root behavior but adds no syntax or format detail beyond the schema, so the baseline 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 (Read) and resource (public discussion threads) and scopes it to entity/topic/section targets. It partially differentiates from siblings by noting community content is separate from the KG, which distinguishes it from search_knowledge_graph and get_knowledge_entity, though it never names closer siblings like get_popular_feedback or list_community_feed.

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 implied through 'Reading is free of search and LLM calls,' hinting this is the cheap way to read discussion, but there is no explicit when-to-use versus get_popular_feedback or list_community_feed guidance. No exclusions or alternatives are named.

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