send_campaign

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

No annotations are present, so the description carries the burden. It indicates the action is a write operation and imposes a precondition, but fails to detail side effects (e.g., error handling for invalid status, idempotency) or return value behavior. The output schema exists but is not described.

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, front-loaded with the core action and condition. Every word adds value, with no redundancy or fluff.

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?

Given the output schema exists, return values need not be described. However, the description lacks information on error conditions, what happens if the campaign is already sent, or any other behavioral details that would help an agent handle the tool safely. It is adequate for a simple tool but not comprehensive.

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 description does not mention the lone parameter 'campaign_id' at all. With 0% schema description coverage, the description should compensate, but it offers no explanation of how the parameter is used or its role in the operation.

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 the action ('send a campaign'), specifies it happens immediately, and provides a prerequisite (campaign must be in 'save' status with content set). This distinguishes it from siblings like schedule_campaign or cancel_campaign.

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 description implies usage when the campaign is ready to be sent immediately, but does not explicitly exclude other scenarios or mention alternatives like schedule_campaign. The prerequisite offers context for appropriate use.

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