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

The annotations already indicate this is a non-read-only, non-idempotent mutation. The description adds no extra behavioral context such as side effects, required permissions, or duplicate handling; it merely restates the action and parameter hints, offering minimal added transparency.

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 consists of two short sentences with the action front-loaded and no filler. Every word earns its place, and it is appropriately sized for a simple create operation.

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 output schema and full schema coverage, the description adequately covers the core purpose and two optional associations. However, it lacks contextual details such as when to use this tool over update_task or list_tasks, and does not provide any business context about tasks. It is minimal but functional.

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%, so the baseline is 3. The description adds meaningful semantics for two parameters: 'link to a CRM account' clarifies accountId and 'assign to a team member' clarifies assigneeId, providing human-readable intent beyond the schema descriptions.

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 uses the specific verb 'Create' with the resource 'task,' making the primary action clear. It also mentions optional linking to a CRM account and team assignment, but it does not explicitly distinguish itself from other create_* siblings beyond the resource name.

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?

No guidance is provided on when to use this tool versus alternatives like update_task or list_tasks. The usage is only implied by the verb 'Create,' and no exclusions or alternative tool references are included.

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