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

No annotations are provided, so the description carries the full burden of disclosure. It fails to mention that the tool is likely read-only, does not describe pagination behavior (skip/limit), or clarify if it requires specific permissions. The description is too minimal to inform the agent about behavioral traits.

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 a single concise sentence, but it is under-specified. While brevity is positive, the lack of detail outweighs the conciseness, making it only adequate.

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?

Given the tool has 4 parameters (2 required, with defaults) and an output schema, the description does not explain how to use the parameters, what a thread message is, or the expected behavior (e.g., ordering, pagination). The description is insufficient for an agent to correctly invoke the tool without external knowledge.

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?

With 0% schema description coverage and no parameter explanations in the description, the agent receives no additional meaning beyond the schema's field names and types. The description does not explain what 'id', 'message_id', 'skip', or 'limit' represent in the context of thread messages.

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 'Get Channel Thread Messages' uses a specific verb ('get') and resource ('channel thread messages'), clearly distinguishing it from sibling tools like 'get_channel_messages' (non-thread) and 'get_channel_message' (single message). The 'thread' qualifier provides differentiation.

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?

The description provides no guidance on when to use this tool versus alternatives such as 'get_channel_messages', 'get_channel_message', or 'get_pinned_channel_messages'. No context about prerequisites or specific use cases is given.

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