Create a press release

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

With no annotations provided, the description carries the burden of disclosing behavior. It mentions that free accounts receive an error, which is a clear behavioral note. However, it does not describe success behavior (e.g., what is returned) or any side effects, leaving some behavioral aspects unspecified.

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 a single, focused sentence that puts the primary action first ('Creates a new press release / blog article') and then adds the essential membership constraint. It is concise with no extraneous information, making it easy to parse and act upon.

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?

The schema is simple (flat, no enums, no nested objects) and the description covers the core purpose and a key constraint. However, it lacks any mention of return values or the distinction between creating a draft and publishing (sibling tools include post_press_release). This omission leaves some contextual ambiguity for an agent deciding which tool to use.

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 already provides descriptions for all parameters (100% coverage), so the description adds no additional meaning to the parameters. The tool description does not clarify parameter usage beyond what the schema already states, keeping it at the baseline for high schema coverage.

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 tool's function: 'Creates a new press release / blog article.' It explicitly names the resource (press release) and the action (create), and the mention of 'blog article' broadens its scope. This effectively distinguishes it from sibling tools like create_banner or create_youtube_ad.

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 provides a business constraint ('Requires a paid membership') and notes an error condition for free accounts, but it does not offer comparative guidance on when to use this tool versus alternatives such as update_press_release or post_press_release. There is no explicit instruction about selecting this tool over others for creating versus updating or publishing.

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