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

With no annotations provided, the description carries the full behavioral burden and does so well: it warns that this publishes a public comment, appears on someone else's post under the user's name, and counts against their daily comment limit. These are exactly the side effects an agent needs before invoking a public posting action.

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 front-loaded and well structured with a clear warning, usage note, and parameter list. The trailing 'Responses: 200' section is low-value boilerplate given there is no output schema, but the rest is efficient.

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 complexity of a public-posting action with three parameters and no annotations or output schema, the description covers purpose, required user consent, side effects, and every parameter's meaning and omission behavior. Nothing essential for correct invocation is missing.

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, and it does: handle is tied to list_comment_drafts, comment_text is a replacement that can be omitted to post the draft as written, and comment_at accepts 'now', ISO-8601 with offset, or omission to let Iridium pick a time.

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 states a specific verb and resource: approve one comment draft and schedule it to post. It explicitly distinguishes the action as publishing a public comment, separating it from siblings like approve_content_draft or approve_reply_draft.

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 gives a clear usage condition: call only when the user has explicitly approved this specific comment. It also warns that the action counts against the daily comment limit. However, it does not explicitly name alternative tools like edit_comment_draft or skip_comment_draft for adjacent workflows.

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