Delete account cron job

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

Annotations already provide destructiveHint=true, readOnlyHint=false, and idempotentHint=true. The description adds 'permanently' to emphasize irreversibility, which is a useful nuance beyond the raw destructive flag. It does not discuss side effects, permissions, or behavior on repeated/nonexistent uids, but no contradiction with annotations exists.

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 sentences with no filler. The deletion action is front-loaded, and the second sentence provides exactly the provenance needed for the uid. 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?

For a simple two-parameter delete tool, the description and annotations are largely sufficient: the target is identified, the uid source is given, and the destructive nature is covered. Minor gaps remain, such as the meaning of the required username parameter and what the response will look like, but these are unlikely to prevent 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?

Both parameters are covered by schema descriptions, so the baseline is 3. The description reinforces that uid is the identifier from the list cron jobs endpoint, matching the schema. It does not add useful meaning for the username parameter, whose schema description 'username parameter' is essentially a tautology.

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 concrete action ('Permanently deletes') and identifies the exact resource ('the cron job identified by its uid'). The title and tool name clarify it is an account-level cron job, which helps distinguish it from website-level cron job tools. However, the description itself does not explicitly differentiate it from sibling cron deletion endpoints.

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 description gives a clear precondition: the uid must come from the list cron jobs endpoint, which tells the agent where to obtain a valid identifier. It does not name alternative tools or state when not to use it, but for this simple deletion operation the usage context is reasonably clear.

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