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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is largely covered. The description adds the shared-scope consequence ("for everyone who could use it") and reversibility ("cannot be restored"), which is useful but closely overlaps the destructiveHint the agent already sees. No mention of auth requirements or failure modes.

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?

Two short sentences, front-loaded with the action and resource, each earning its place. No hedging or filler.

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 single-parameter destructive tool whose annotations carry the safety hints, the description supplies the scope and irreversibility an agent needs before calling. An output schema is unnecessary for a delete, and little is missing.

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?

Only one parameter at 100% schema coverage, and the schema already explains it is the id from list_saved_replies. The description contributes nothing about the parameter, so the baseline 3 applies.

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 (delete) and resource (saved reply), making it immediately distinguishable from siblings like delete_email_template or delete_journey. It stops short of naming a sibling or contrasting scope, but the action is unambiguous.

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?

The phrase "for everyone who could use it" implies the operation removes a shared/workspace resource rather than a personal draft, which nudges usage. However, there is no explicit when-to-use, when-not-to-use, or pointer to an alternative such as update_saved_reply if the intent is only to modify.

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