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

The description explicitly states the operation is "permanent," which directly conflicts with the annotation destructiveHint=false (a hint that means only additive changes occur). An agent trusting the annotation would treat this as non-destructive and skip confirmation. The description is the accurate side here, but the contradiction is the dangerous part.

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, with the destructive consequence and the confirmation requirement front-loaded. Nothing is redundant and nothing needed is buried.

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 one-parameter mutation with no output schema, the description covers what is removed, that it is irreversible, and that the ID should be verified first. The remaining gap is the unresolved conflict with the destructive hint, which an agent cannot reconcile from the description alone.

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?

There is a single parameter at 100% schema coverage, and the schema already explains the ID comes from creation or listing. The description only adds a confirmation instruction, which is workflow rather than additional semantics for alert_id.

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?

"Delete one of your price alerts" names a specific verb (delete) and resource (price alert), and the verb alone separates it from list_market_alerts, create_market_alert, and update_market_alert. No agent could confuse this with a sibling.

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 supplies a concrete pre-call workflow ("confirm the alert ID with the user before deleting") and a clear consequence that governs use. It does not mention alternatives — e.g. that update_market_alert should be used to modify rather than remove an alert — so it stops short of a 5.

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