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

With no annotations, the description carries the behavioral burden and explicitly flags irreversibility, a confirmation requirement, and per-platform outcome recording. This is valuable for a potentially destructive publish action, though it does not discuss failure modes or authentication/permission requirements.

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?

Three short sentences front-load the essential action and then add the critical warnings. There is no filler or repetition of schema details.

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 two-parameter tool, the description is largely sufficient: it identifies the object, target, timing, irreversibility, and per-platform outcome. It could be more complete by noting how confirmation is obtained or what the response format is, but the sibling ambiguity is the main gap.

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?

At 0% schema description coverage, the description compensates by explaining that postId refers to a prepared post and platforms are the targets, with a published-outcome recorded per platform. It leaves detailed enumeration to the schema's platform enum, which is appropriate.

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 names a specific verb ('Publish'), resource ('prepared post'), identifier (postId), and target ('platforms'), and adds the per-platform outcome. It is clear on its own, but it does not distinguish itself from the near-identical sibling 'publish_post_now'.

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 context is implied: the post must already be prepared and the action should only happen after confirmation because it is irreversible. It does not explicitly state when to choose this tool over alternatives such as schedule_post or publish_post_now, so an agent must infer selection criteria.

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