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

Beyond the destructiveHint and idempotentHint annotations, the description explains the concrete effect (PermitSnag stops checking and sends no more openings), the reversibility path (can be turned back on from the website), the blast radius (never cancels a booking, permit application, or paid plan), and the no-op case. That is unusually thorough behavioral disclosure for a mutation tool.

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?

Four short sentences, each carrying distinct information: scope, source of the id, side effects, reversibility, and safety boundary. The scope statement is front-loaded and nothing is redundant.

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?

With one required parameter, full schema coverage, an output schema, and annotations covering safety and idempotency, the description supplies everything else an agent needs. No gaps remain that would affect correct invocation.

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 description coverage is 100%, so the alertId parameter is already documented as "The alert id from list_my_alerts." The description reinforces that provenance but adds no new format, validation, or constraint information beyond the schema, 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?

The description states a precise verb and resource ("Turn off one alert"), scopes it to "the person's own linked PermitSnag account," and ties the identifier to the sibling tool list_my_alerts, so an agent can distinguish it from create_alert or list_my_alerts without reading 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?

It tells the agent where the alertId comes from (list_my_alerts) and that re-enabling happens on the website rather than through a tool, which implicitly rules out a companion "enable" call. It does not spell out an explicit when-not-to-use condition, but no sibling competes for the same action.

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