cancel_campaign

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

Discloses that pending steps are skipped, but lacks details on reversibility, authorization needs, or side effects. With no annotations, the description should provide more behavioral context.

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?

Extremely concise with no redundant information. Two sentences plus a clear argument description.

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?

Despite having an output schema, the description omits important mutation aspects like reversibility, permission requirements, and impact on other campaigns. Siblings like pause_campaign suggest alternative behaviors, but no comparison is provided.

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?

Adds that 'id' is a Campaign UUID, which is not in the schema. However, it does not describe valid UUID format or where to obtain it. Schema coverage is 0%, so minimal compensation.

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 clearly states it cancels a campaign and notes that pending steps are skipped. This verb+resource combination distinguishes it from pause_campaign or abort_branch.

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 guidance on when to use this tool versus alternatives like pause_campaign or abort_branch. The description does not mention prerequisites or scenarios.

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