Bulk Create Action Plan Template Item Assignees

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

Beyond the annotations (readOnlyHint false), the description discloses that the operation can have partial failures and returns the created collection with HTTP 201. This adds value by warning about partial success behavior and confirming the response status code. It does not describe error handling or response format in detail, but is sufficient.

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 four sentences but contains redundancy (repeats 'creates many Action Plans records'). It is structured with a title, usage, behavior, and required parameters, but repeats information unnecessarily. Could be more succinct without losing clarity.

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?

Given the tool has 3 parameters (all described in schema) and no output schema, the description covers the purpose, basic usage, and partial failure behavior. However, it lacks details on response structure, handling partial failures, or differentiating from similar bulk create tools. It is adequate but not comprehensive.

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 coverage is 100% (all parameters are described in the schema). The description merely lists required parameters (project_id, plan_template_item_assignees) already present in the schema, without adding semantic meaning about what values the fields accept or expected formats. It meets the baseline but does not exceed it.

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 states it's for bulk creating Action Plan Template Item Assignees in a single request. It mentions required parameters and the endpoint. However, there is a minor inaccuracy where it says 'create many Action Plans records' instead of 'create many Action Plan Template Item Assignees', and it does not differentiate from sibling tools like the company-level or item-level assignees versions.

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 context ('use this to create many... in a single request') and notes partial failures. However, it does not explicitly state when to use this tool over alternatives (e.g., company vs project, or item-level assignees), nor does it mention prerequisites or when not to use it.

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