wordpress_bulk_update_posts

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

With no annotations, the description is the only source of behavioral details. It only states the core action and an efficiency claim, but does not disclose whether the operation is atomic, what happens on partial failure, permission requirements, or the response format. For a mutation tool, this is a significant gap.

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 concise sentence that front-loads the key information ('Update multiple posts') and adds a small value statement. No wasted words.

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 one required parameter with an unclear structure, no output schema, and no annotations. The description does not explain how to construct the updates array or what response to expect, making it insufficient for an agent to invoke correctly. The minimal wording leaves critical invocation details unaddressed.

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 only defines 'updates' as an array with no item structure. The description says 'Update multiple posts' but does not clarify what the array should contain (e.g., IDs, field objects). With 0% schema coverage, the description needed to compensate but did not, leaving the parameter ambiguous.

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 says 'Update multiple posts in one operation' which clearly specifies the action (update) and resource (posts) while distinguishing it from singular update_post and bulk_create/bulk_delete siblings. The phrase 'multiple posts' makes the bulk scope explicit.

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?

'Efficient for batch modifications' implies the tool is intended for updating several posts at once, but it does not explicitly name alternatives like wordpress_update_post for single updates or exclude cases like needing different field structures. The guidance is implicit rather than explicit.

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