task.analysis_update

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

With no annotations provided, the description must fully disclose behavior. It only states 'async' and 'start', implying non-blocking execution, but omits critical details: cancellation options, side effects, how to monitor or retrieve results, and any resource implications.

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?

At four words, the description is extremely concise, but this brevity sacrifices essential information. Every word is functional, but the description is under-specified for an agent to use effectively.

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 simple schema but rich sibling context (many analysis-related tools), the description is incomplete. It does not explain return values (no output schema), how to track the async task, or how this tool relates to analysis.update and analysis.update_and_wait, leaving key gaps for correct invocation.

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 0% and the description does not mention the session_id parameter at all. The parameter name hints at a session identifier, but the tool description adds no meaning beyond what the schema field name conveys, failing to compensate for the lack of 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 'Start async analysis update task' uses a verb phrase specifying the action (start) and resource (async analysis update task). It implicitly distinguishes from siblings like analysis.update (likely synchronous) and analysis.update_and_wait by emphasizing 'async', but it doesn't define what an analysis update involves.

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 async variant versus synchronous alternatives like analysis.update or analysis.update_and_wait. There is no mention of prerequisites, conditions, or situations to avoid, leaving the agent without decision criteria.

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