update_task_status

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

With no annotations, the description carries the full burden, yet it omits permissions required, side effects, idempotency semantics (despite an idempotency_key being required), and reversibility. The one clarifying statement about external approval is genuinely useful context but far short of what a mutation tool with zero annotation coverage needs.

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?

A single short sentence is efficient but cryptic; the most important content (what status is being set, on what object) is not front-loaded or stated at all. Length is fine, informativeness is not.

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 described, but for a three-parameter mutation tool with no annotations and no enum guidance on status, the description leaves too much unspecified for an agent to invoke it confidently.

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% across three required parameters, and the description names none of them. It gives no hint about valid status values, the meaning of task_id, or how idempotency_key governs retries, so it fails to compensate for the schema gap.

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 a vague action ('Record processing outcome') that loosely maps to the tool name update_task_status but never names the resource or the status field explicitly. It does add a distinguishing semantic (it is not an owner's external approval), which helps separate it from cancel_task or send_coordination, but the core purpose is only implied.

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 guidance on when to call this versus siblings such as cancel_task, get_task, or send_coordination. The single clause about external approval hints at a usage boundary but never states the conditions under which the tool should be invoked.

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