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

Goes well beyond the annotations (destructive, non-idempotent, open-world) by explaining that the call only queues the comment, that it returns status pending with scheduled_for, that posting can be delayed by posting windows or hourly limits, and that delivery is irreversible once live. It also documents the comment_commit_blocked / COMMENT_ALREADY_POSTED failure paths, which no annotation could convey. Nothing here contradicts destructiveHint=true or idempotentHint=false; it reinforces both.

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?

Front-loaded with the crucial 'this only schedules, it is NOT live' correction, then layered with follow-up, cancellation, retry, and error semantics. It is dense and long, but each sentence carries distinct operational information; the error-code sentences in the tail could be tightened.

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?

Covers everything an agent needs despite an output schema being present: the queued semantics, the fields to quote back (scheduled_for), the follow-up verification path, the irreversibility boundary, retry safety, and the duplicate-comment rejection codes. Complete for a non-idempotent, destructive, open-world mutation.

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 coverage is 100% and the single parameter is already documented, so the baseline is 3. The description adds only mild value by framing the id as a draft to be scheduled rather than an already-posted comment, but the bulk of parameter meaning is still carried by the schema.

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?

States a specific verb and resource (commit a comment draft) and immediately clarifies the actual effect: it schedules a comment to be posted on LinkedIn under the user's name on someone else's post. That distinguishes it from the neighboring draft/schedule/publish siblings without the agent needing to open any schema.

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?

Explicitly names the follow-up and alternative tools and the conditions that select them: get_comment_draft to confirm the outcome, cancel_comment_draft to stop it before sending, and the fact that it is unsafe to retry because a re-commit is rejected. When-to-use and when-not-to-act guidance is fully covered.

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