assign-categories-to-posts

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only says 'Bulk assign categories to multiple posts' and does not disclose whether existing categories are replaced or added, whether the operation is idempotent, or any side effects. The replaceExisting parameter is not mentioned, leaving a significant gap for a mutation tool.

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, front-loaded sentence that directly states the core function with no filler. It is concise and every word earns its place.

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 tool has three parameters, no output schema, and no annotations. The description is minimal and omits critical operational context, such as the add-versus-replace behavior, potential implications of bulk editing, and any prerequisites. The schema covers parameters but not the broader workflow, leaving the agent under-informed.

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 schema description coverage is 100% with clear descriptions for postIds, categoryIds, and replaceExisting. The tool description adds no parameter semantics beyond the schema, so the baseline of 3 is appropriate.

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 'Bulk assign categories to multiple posts' clearly states the specific action (assign), the resource (categories to posts), and scope (bulk/multiple). It distinguishes from sibling tools like assign-tags-to-posts by specifying 'categories' and from single-post tools like update-post.

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 no guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or alternative tools such as assign-tags-to-posts or update-post. No context is given for when bulk assignment is appropriate.

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