Empty Trash

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

Goes beyond annotations: emphasizes 'PERMANENTLY', 'UNRECOVERABLE', and 'bypasses the move-to-Trash safety net'. Clearly conveys destructive nature and requirement for confirmation.

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 sentences with no waste. Front-loaded with the critical purpose and severity. Every sentence earns its place.

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?

Covers purpose, usage, behavioral details, and parameter requirement. With output schema present, return value explanation is unnecessary. Complete for a low-complexity tool.

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 100%. Description adds context that 'confirmed' must be true and stresses unrecoverability, reinforcing schema info. Provides slight additional meaning.

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?

Clearly states the verb 'PERMANENTLY delete' and resource 'every message in the Trash mailbox'. Distinct from siblings like move_to_trash and delete_email by specifying it bypasses the safety net and empties the entire trash.

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?

Explicitly states when to use (permanent deletion of all trash) and that it only touches Trash mailbox, never live mail. However, no explicit alternatives when not to use, though implication is strong.

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