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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing. For a destructive delete it says nothing about whether rows/assets are cascaded, whether the action is reversible, what permissions are required, or what the confirmation behavior is.

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?

It is short, but the brevity reflects under-specification rather than economy. The only content beyond the name is an API namespace prefix that does not help an agent decide or invoke.

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 destructive operation with no annotations and no output schema, the description leaves every consequential question unanswered: what exactly is removed, whether calendar rows survive, and whether recovery is possible. The schema is trivial, so the description had room to say more and said nothing.

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 optional parameter with 100% schema description coverage, which documents notification_message fully. Baseline 3 applies; the description adds no meaning beyond the schema, but nothing is missing either.

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 is essentially a restatement of the tool name plus an API namespace label ("Audience Resolver publisher API"). It implies deletion of a content calendar, but offers no scope, no object identity, and no differentiation from siblings like delete_calendar_row, delete_calendar_rows, or cancel_publishing_history.

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?

There is no guidance on when to use this tool versus the many adjacent delete/cancel siblings, no prerequisites, and no exclusions. The agent must infer everything from the name alone.

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