Services_cancelServiceJobByServiceJobId

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

With no annotations, the description carries the burden of behavioral disclosure, and it does add one non-obvious fact: this is a catalog entry that runs in the user's Kuudo deployment, not in the current environment. However, it does not disclose cancellation effects, reversibility, required permissions, idempotency, or failure behavior, so the disclosure is only partial.

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 short and scannable, but it front-loads meta context ('Catalog entry. Runs in your Kuudo deployment, not here.') before the actual behavior, and the first two sentences are somewhat redundant. The core action could be stated more directly and compactly.

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 mutation tool with no annotations and no output schema, the description leaves important gaps: how the service job identifier should be provided, what a successful cancellation returns, and whether there are preconditions on the job state. The Kuudo deployment note is useful, but an agent still lacks enough detail to invoke the tool confidently.

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 input schema defines no properties, so the description's mention of a 'service job identifier' is the only parameter information available. It signals that an identifier is required but does not specify the parameter's exact name, location, type, or format, leaving the agent to infer serviceJobId from the tool name.

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 sentence 'Cancels the service job indicated by the service job identifier specified' clearly states a specific action and resource, and it distinguishes cancellation from sibling operations such as completing or retrieving a service job. The 'Catalog entry' and environment note add context without obscuring the core purpose, though the description does not explicitly contrast it with alternatives.

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?

There is no guidance on when to use this tool versus related tools like Services_completeServiceJobByServiceJobId, Services_getServiceJobByServiceJobId, or Services_cancelReservation. The note 'Runs in your Kuudo deployment, not here' is an environment caveat, not a selection rule, and prerequisites such as job state or whether the job can still be cancelled are not mentioned.

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