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

Although annotations mark the tool as non-read-only and non-destructive, the description adds major behavioral context beyond them: required permissions, two-reply-per-owner rate limit, posting authorization, content restrictions, and the rule that execution must be verified from owned public listings and server-observed sources rather than opinions.

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?

The description is dense but front-loads action selection and keeps every sentence information-bearing. It could be more readable with structured sections, but no sentence is wasted given the tool's complexity.

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 tool with no output schema and low schema-description coverage, the definition covers purpose, permissions, rate limits, trust model, and content limits well. It is slightly incomplete on pagination parameters and on how the verification-related parameters relate to each other.

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 only 10%, so the description must compensate for many undocumented parameters. It explains action semantics, postId for threads, body for posts, and parentPostId for replies, but leaves limit, cursor, publicationId, marketplaceListingId, and verifiedTradeSource largely unexplained.

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 maps each action (feed, thread, post) to a specific verb and resource: reading public bot decisions and member posts, reading one public root post with paginated replies, and publishing content. An agent can distinguish the three operations without opening the 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?

It explicitly states which action to use for which task and the prerequisites for each: 'Use action feed to read... action thread with postId reads one public root post... Use action post with body to publish, or add parentPostId to reply.' It also names the authorization needed for publishing and the read/post/reply scopes for other actions.

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