revoke_cancel_domain

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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond a restatement of the title – it does not say what revoking the cancellation restores (renewal/billing), whether it can be undone, or what happens if no cancellation is pending.

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?

Very short, but the same sentence is repeated verbatim after the HTTP path, which is pure waste. Front-loading is fine (the verb+resource comes first), but the duplication suggests an auto-generated description with no editing.

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 state-changing domain operation with no output schema, the description leaves important context unstated: the intermediate state required for it to succeed, the resulting domain status, and any billing/renewal implications. An agent could call it in the wrong lifecycle state and get an error it cannot predict.

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 description coverage is 100%, so both the 'domain' path parameter and the 'x-trace-id' header are already documented in the schema. The bracketed path hints that 'domain' is a path segment, but no format or example is added, so this is baseline.

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 plus resource ('Revoke cancellation for a specific domain') and includes the HTTP path, which makes the effect clear without opening the schema. It is distinguishable from the sibling cancel_domain by the word 'revoke', though the description never names that sibling as its inverse.

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?

No statement of when to use this versus cancel_domain, no prerequisites (e.g. that the domain must currently be in a cancellation state), and no exclusions. The agent must infer the usage from the tool name alone.

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