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

With no annotations, the description carries the full burden and does disclose a non-obvious cascading side effect: it deletes every ignore rule (page, site-wide, route-pattern) and explains why. It still omits auth requirements, reversibility of those deletions, and error behavior when no rules exist.

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 tight sentences, front-loaded with the action and followed by the critical side effect and its rationale. No filler and nothing redundant with the schema.

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 mutation with no annotations and no output schema, the description covers the action and the important destructive consequence. It leaves a minor gap around response behavior and what happens when there are no ignore rules to delete.

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% for the single alertId parameter, so the schema already documents the input. The description adds no format, sourcing, or validity detail beyond that, which is the baseline-3 case for a one-parameter tool.

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?

"Reopen an ignored alert" states a specific verb and resource, and the concept of undoing an ignore makes it implicitly distinguishable from the sibling ignore_alert. However, it never names the sibling it inverts, so an agent must infer the pairing from semantics rather than being routed explicitly.

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 usage is implied by the verb (reopen something previously ignored), and the note about deleting ignore rules gives a strong hint about when this is the right call. But there is no explicit when-to-use vs. when-not statement and no named alternative such as ignore_alert.

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