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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the description should clarify what is destroyed or replaced and whether the update is partial or full. Instead the only behavioral content is about approval requirements, which is useful but does not address the mutation semantics the destructive hint demands.

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 short sentences with the operation stated first, so it is front-loaded and wastes little space. The approval sentence is borderline boilerplate but does carry real information about governance.

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?

An output schema exists so return values need not be explained, but this is a destructive, non-idempotent mutation with a nested data object and zero parameter documentation. The description leaves an agent without the information needed to call it correctly or safely.

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 adds nothing about the three required parameters. Critically, it never explains the difference between "id" (presumably the template) and "itemId" (the item within it), nor what fields of "data" are updatable or whether omitted fields are cleared.

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?

"Edit a project_task template item" gives a verb and a resource, but the sibling list contains update_project_task_template, update_task_template_item, update_project_task, and update_checklist_template_item, and the description does nothing to distinguish this tool from them. An agent can identify the general domain but not the precise object level (template item vs. template vs. live task).

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?

There is no statement of when to use this tool versus alternatives, and no prerequisites beyond a vague note that approvals may be configured by an administrator. The agent must infer that this is for modifying an existing template item and must guess how to disambiguate it from the near-identical sibling updaters.

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