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

Adds behavioral context beyond annotations: execution is asynchronous, returns an operation ID, and the quote bounds spending and rights scope. No statement contradicts the readOnly, destructive, or idempotent hints.

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?

Three compact sentences with the core action front-loaded. Every sentence earns its place: async behavior, return/polling, and the removal distinction are all covered without redundancy.

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 low-complexity, 2-parameter async tool with no output schema, it covers the operation, return value, polling step, and a key exclusion. It omits idempotency-key semantics and failure/operation state behavior, but the essential call path is clear.

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%, so the description must compensate. It loosely describes what the quote contains (spending bounds, rights scope) but never names quote_id, and idempotency_key is not explained at all.

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?

States a specific verb and resource: 'Execute a pre-approved monitor quote asynchronously.' The phrase 'pre-approved' distinguishes it from quote creation, and 'Submission is distinct from removal' disambiguates it from takedown/removal tools.

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?

Clear context is provided: use only with a pre-approved quote, expect async execution, and poll get_operation for the result. The exclusion 'distinct from removal' gives a when-not signal, though it does not name sibling alternatives such as pause_monitor or resume_monitor.

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