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

Annotations already flag destructiveHint=true and readOnlyHint=false, so the description only needs to add context, and it does: the token is exact and single-use, calls cannot be rewritten/replayed, and the reply is a result, not an approval handle/JSON/debug internals. It doesn't detail the destructive side effect itself, but the annotation plus operation names cover the safety profile.

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 telegraphic sentences front-load the core constraint (exact single-use token) before alternatives and response format. No filler; every clause adds decision-relevant information.

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 confirmation tool with an output schema and safety annotations, this is complete: it covers when to use, what token to pass, what not to do, and where to go on failure. No critical workflow information 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?

With 0% schema description coverage, the description must carry parameter semantics, and it names confirm_token and its key constraints: exactness and single-use. That is meaningful beyond the schema's bare string type, though the token's source or exact format is left implicit; the lost-token routing partly compensates.

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 first clause names the exact operation family (QuickCreate/copy/recreate/clone) and the action (confirming an approved launch), so the tool's role is unambiguous. It also distances itself from the lost-token flow by naming operations_get_approval and operations_confirm_approval, which differentiates it from approval-workflow siblings.

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 explicitly states when to call: after approval for QuickCreate/copy/recreate/clone with an exact confirm_token. It also states when not to: if the token is lost, get the approval and use operations_confirm_approval instead, and never rewrite or replay.

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