Bulk Update Action Plan Template Item

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

Beyond annotations (readOnlyHint=false, destructiveHint=false), the description discloses the partial update behavior ('only the supplied fields are changed') and confirms the return of the modified object. However, it omits details like permissions or error handling.

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 reasonably concise with 4 sentences, but it contains repetitive language ('Updates multiple Action Plan Template Items' and 'Updates the specified Action Plans') and a slight inconsistency in naming.

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 description lacks critical context such as how to use the completion_mode parameter, the expected structure of plan_template_items array, and error scenarios. Given the absence of an output schema, more details on return format would be helpful.

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?

With 100% schema coverage, the description adds minimal new parameter information (only lists required params, which the schema already shows). It does not explain the meaning of completion_mode enum values or the structure of plan_template_items beyond what the schema provides.

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 updates multiple Action Plan Template Items. However, it inconsistently references 'Action Plans' instead of 'Action Plan Template Items', and does not explicitly differentiate from similar siblings like 'bulk_update_action_plan_template_item_company'.

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 basic usage guidance ('Use this to update an existing Action Plans') but does not include when to avoid this tool or mention alternative tools for company-level updates.

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