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

No annotations are provided, so the description carries the full behavioral burden and discloses nothing. It does not say whether this is a mutation, what happens to rows already scheduled, whether it requires publishing permissions, whether it is reversible, or what the result contains. For a bulk scheduling operation this is a serious gap.

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 comes from under-specification rather than efficiency. The one sentence is a label, not a front-loaded purpose statement, and it contains no information an agent could act on.

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 no annotations, no output schema, and a bulk mutation whose scope and side effects are undefined, the description leaves everything an agent needs unanswered. It is inadequate for a tool that likely modifies many calendar rows at once.

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 single notification_message parameter is fully documented in the schema itself, which sets the baseline at 3. The description adds nothing about the parameter, but the schema does the work.

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 a restatement of the tool name prefixed by an API label ('Audience Resolver publisher API'), not an explanation of what scheduling all calendar rows means. It never states the resource scope (all rows in a calendar? all calendars?) or a verb-plus-object description beyond the identifier. An agent cannot distinguish it from the sibling schedule_calendar_row from this text.

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?

No when-to-use, when-not-to-use, or prerequisite information is given. The sibling list contains schedule_calendar_row and unschedule_calendar_row, which are obvious alternatives for the same resource, yet the description offers no criteria for choosing bulk vs. single-row scheduling.

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