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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered. The description's 'Permanently removes the record and cannot be undone' reinforces permanence but adds little beyond destructiveHint, and says nothing about permissions, error behavior for missing IDs, or side effects on related data.

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 short sentences, front-loaded with the action and the required argument, followed by the irreversibility warning and the sibling routing hint. No 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 with no output schema and annotations covering safety, the description supplies the required argument, the permanence warning, and the read-side alternative. Only failure/idempotency behavior is unstated, which is a minor gap given the annotations.

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 and schema description coverage is 100%, so the schema already documents `id` fully. 'Requires `id`' restates the schema without adding format, source, or retrieval guidance, which matches the baseline 3 for a fully-covered single parameter.

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 ('secretsmanager') with the scoping constraint 'by its ID from the connected account.' An agent can distinguish it from get_unified_secretsmanager and list_unified_secretsmanagers without opening any schema.

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 routes to `get_unified_secretsmanager` when the goal is retrieval rather than removal, and flags the operation as permanent. It does not state when deletion should be avoided (e.g., prerequisites, dependent resources), so it falls short of full when/when-not guidance.

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