Update comment

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 reveals that only pending comments can be edited and that text/scheduledAt are independently updatable, but it omits permissions, error behavior for non-pending comments, side effects, and return values.

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?

A single, front-loaded sentence with no filler. It conveys the action, target, and editable fields efficiently.

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 update tool with three parameters and no output schema, the description gives the core information needed. However, the lack of annotations, date format guidance, and any mention of constraints or failure cases leaves meaningful gaps for an agent to call it correctly in edge cases.

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%, so the description must compensate. It usefully maps 'text' and 'due time' to the text and scheduledAt parameters and implies optionality via 'and/or', but it does not explain the scheduledAt format or clarify that commentId is the target identifier beyond the schema's required field.

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 ('Edit'), the resource ('pending comment'), and the editable fields ('text and/or due time'). This also distinguishes it from siblings like create_comment, delete_comment, and update_post.

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 phrase 'pending comment' implies when to use this tool, but there is no explicit guidance about when not to use it or how it differs from alternatives like update_post or reschedule_post. The usage context is present but mostly inferred.

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