create_meta_campaign

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

With no annotations, the description carries full burden and discloses key behavioral traits: the campaign is created in PAUSED state (requiring separate activation), has a minimum budget constraint, and requires a specific subscription plan. It doesn't mention rate limits, error handling, or response format, leaving some gaps.

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?

Front-loaded with core purpose, followed by essential behavioral details in a single, efficient sentence. Every clause adds value with no wasted words, making it easy to scan.

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 complex creation tool with no annotations or output schema, the description covers purpose, usage context, and key constraints well. It could improve by hinting at return values or error cases, but it's largely complete given the structured input schema.

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 the schema fully documents all 9 parameters. The description adds no parameter-specific information beyond what's in the schema, meeting the baseline for high coverage but not enhancing understanding.

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 verb ('Create') and resource ('complete Meta ad campaign') with specific scope ('campaign + ad set with targeting + creative + ad'), distinguishing it from siblings like 'create_tiktok_campaign' (different platform) and 'enable_meta_campaign' (different action).

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?

Explicitly states when to use ('Create a complete Meta ad campaign in one call') and when not to use ('Created in PAUSED state. Call enable_meta_campaign to activate'), with clear prerequisites ('Requires Starter plan or higher') and constraints ('Minimum budget $1/day').

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