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

With no annotations present, the description carries the behavioral disclosure burden. It does usefully disclose that withdrawal takes effect immediately and that subsequent claims and completions are blocked, which are decision-relevant side effects for a mutating tool. It does not cover idempotency, reversibility, or permissions, but the most critical behavioral consequence is stated.

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 two short sentences with the core action front-loaded and the consequence in the second sentence. There is no filler or redundant restatement of the tool name, making it appropriately compact for a simple mutation.

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 single-parameter mutation with no output schema and no annotations, the description covers the main action and its blocking effect. However, it omits what the id parameter identifies and gives no indication of return behavior or failure cases, so fully confident invocation still requires inference.

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 schema has 0% description coverage and only defines id as an integer with minimum 1. The description never explains what id refers to, leaving the agent to infer that it is an offer ID from the tool name and sibling tools like list_compute. This is a real gap that the description fails to compensate for.

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-resource pairing: withdrawing a resource offer, and adds a meaningful consequence: further claims and completions are blocked. It clearly differentiates from sibling job-related tools like cancel_compute_job by framing this as an offer withdrawal, though it never explicitly names an alternative.

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 intended situation is implied: the agent should call this when it wants to retract a previously made resource offer. However, there is no explicit when-to-use or when-not-to-use guidance, and no mention of how this compares to related tools such as offer_compute or cancel_compute_job.

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