reply_to_discussion_entry

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. The description merely restates the action without mentioning side effects, permissions, reversibility, or what happens after replying. It does not disclose that this is a write operation or any other behavioral traits beyond the obvious action implied by the name.

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 short sentence, which is concise but under-specified. It adds no context beyond the action itself and does not front-load any critical information. The structure is not helpful for an agent seeking to understand when and how to use the tool.

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 required parameters, no annotations, and an output schema that is not described in the definition, the description is wholly inadequate. It does not mention any prerequisites (e.g., existing topic/entry), the expected response shape, or any nuances that would help an agent invoke it correctly. The tool is yet another discussion-related operation among many siblings, and this description does nothing to place it in context.

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 0%, meaning the description must compensate for the lack of parameter documentation. The description does not explain any of the four parameters (course_identifier, topic_id, entry_id, message) or provide any additional meaning beyond their names. This is a significant gap.

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: 'Reply to a specific entry in a discussion topic.' This is a specific verb and resource, and it distinguishes from siblings like 'post_discussion_entry' (creating a new entry) and 'list_discussion_entries' (listing entries). It is clear enough for an agent to understand the primary function.

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 like post_discussion_entry or list_discussion_entries. It does not mention any context, prerequisites, or exclusions. An agent would have to rely on the tool name and sibling names to infer usage.

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