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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the description's job is to say what is destroyed; it does exactly that by clarifying that only the scheduled post is removed while published posts stay live on the network. It omits irreversibility, error behaviour for unknown/nonexistent ids, and any auth or rate-limit context, which keeps it below a 5.

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?

Two short sentences, zero filler, with the primary effect front-loaded and the important caveat second. Every sentence earns its place.

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 one-parameter destructive tool with annotations already covering the safety profile and no output schema, the definition covers purpose, intent, and side-effect scope adequately. The remaining gap is the undocumented id parameter and lack of any note on whether deletion can be undone.

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?

The single parameter 'id' has 0% schema description coverage, so the description carries the burden of explaining it, but it never mentions the id at all or says whether it is the Postmately post id versus a network-side identifier. The purpose wording implies 'a post' is identified, but no format, source, or lookup guidance is added.

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 ('Remove a post from Postmately') and adds scope nuance that published posts remain on the network, so the agent understands this affects scheduled posts only. It does not name a sibling such as update_post or reschedule_post to sharpen the distinction, but the resource and effect are unambiguous.

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?

Gives a concrete use case ('so a scheduled post does not go out') and a clear boundary that already-published posts are not affected, which steers the agent away from expecting a network-level delete. It stops short of naming an alternative tool or stating explicit when-not conditions.

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