create_blog_category

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

With no annotations, the description carries the full burden. It discloses that the tool creates a category, returns the new ID, and requires the image to be a hosted URL. It also notes that post-list/blog pages bind to the category, providing useful integration behavior. It lacks detail on permissions or error handling but adds meaningful 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?

The description is two sentences, front-loaded with the main action. It efficiently communicates the purpose, return value, downstream usage, and an image constraint without redundancy or unnecessary detail.

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 simple 3-parameter create tool with no output schema, the description is complete. It explains the return value, how to use it with create_article, and a parameter constraint. The integration with post-list/blog pages gives sufficient context for an agent to invoke it correctly.

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 each parameter already has a description. The tool description only reiterates the image URL requirement, which is nearly identical to the schema's 'Hosted image URL'. No additional syntax or format details are provided beyond the schema, so it meets the baseline.

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 'Create a blog/article category', using a specific verb and resource. It distinguishes this from sibling create_product_category by specifying 'blog/article', and explains the returned category id's role with create_article, which further clarifies its purpose.

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 clear usage context by explaining to pass the returned ID to create_article's category_id, showing when to use this tool for grouping posts. It does not explicitly mention alternatives like create_product_category, but the 'blog/article' qualifier makes the intended domain clear.

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