reply_to_forum_post

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 behavioral disclosure. It states it sends a reply, implying a write operation, but does not mention any side effects, authorization requirements, rate limits, or error conditions. More transparency is needed for a mutation tool.

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 that front-loads the action and target. Every word is necessary, and there is no redundancy or fluff. It is appropriately sized for the tool's simplicity.

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 simple tool with two parameters and no output schema, the description is minimally complete. However, it lacks mention of what the tool returns upon success (e.g., confirmation or message object). Given the context, adding a brief note about the result would improve completeness.

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% with basic descriptions for both parameters. The tool description itself adds no additional meaning beyond the schema. While the schema is adequate, the description could elaborate on allowed formats or constraints for 'content' or 'thread_id'.

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 clearly states the action ('Send a message (reply)') and the resource ('existing forum post thread'). It effectively distinguishes from siblings like 'create_forum_post' (new thread) and 'edit_forum_post' (editing existing), so the agent knows exactly what this tool does.

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 implies usage when you have an existing thread to reply to, but it does not explicitly state when to use this tool versus alternatives. Given sibling tools like 'get_forum_post_messages' and 'list_forum_posts', explicit guidance on when to reply versus read would improve clarity.

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