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

Annotations already establish that this is a non-read-only, non-destructive mutation, and the description adds genuinely useful non-obvious context: MCP approval requirements are organization-configurable and business workflow approvals always apply. It stops short of detailing exact permissions or side effects, but the approval disclosure is substantive beyond the annotations.

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?

Two sentences with the core action front-loaded and no wasted phrasing. The approval sentence is relevant and earns its place, though it is somewhat general.

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 creation tool with a required nested data object and no schema property descriptions, the definition should say more about what an item contains and what id refers to. The output schema reduces the need to explain returns, and the approval context helps, but parameter meaning and usage guidance remain incomplete.

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 0% and the description does not explain that id is the template UUID or what the nested data fields (name, priority, orderIndex, description) mean. The word "item" gives only a vague hint about the data payload, leaving field-level semantics to the bare schema.

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?

"Add an item to a project_task template" states a specific verb and resource, making the core operation clear. It does not explicitly distinguish this tool from close siblings like create_task_template_item or create_project_task_template, but the resource is still identifiable.

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 does not say when to use this tool versus alternatives such as create_task_template_item, list_project_task_template_items, or update_project_task_template_item. The approval sentence is behavioral context, not usage guidance, and no prerequisites or exclusions are given.

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