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

The annotations already declare this as non-read-only, open-world, and destructive. The description adds useful context that no delivery runs immediately, but it does not disclose whether existing delivery settings are replaced, what permissions are needed, or what side effects occur.

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 is front-loaded, tightly written, and uses the final short clause to add a meaningful behavioral distinction. Every sentence carries useful information without repetition.

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?

This is a destructive six-parameter mutation with external delivery channels and no schema parameter descriptions. The description covers the high-level purpose but omits critical details about expected_version, schedule_id, overwrite behavior, and return semantics.

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 six parameters. The description loosely maps the delivery channels to slack, notify, sendTo, and webhook, but it never explains schedule_id, expected_version, or constraints such as version concurrency.

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 specific action (sets delivery destinations) and scopes it to records found by a monitor, naming the supported channel types. It also distinguishes configuration from execution with 'Nothing runs', though it does not name relevant sibling 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?

It implies configuration-time use rather than immediate sending, which helps orient the agent. However, it does not state when to use this over related tools such as send_to_destination or create_webhook, nor does it mention prerequisites.

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