run_content_optimizer

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

With no annotations, the description carries the full burden and does add real value by disclosing that the run is paid (a cost/spending side effect) and requires content:write and spending:execute scopes. However, it says nothing about execution behavior such as whether the run is async/long-running, what state it leaves content in, or whether it is idempotent or repeatable.

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 short, front-loaded sentences with zero filler. The action and its cost/authorization constraints come first, and 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?

The existence of an output schema means return values need not be described, and the description covers cost and scopes. But for an operationally significant paid run that likely triggers background work, the absence of any note on timing, preconditions, or side effects leaves an agent under-informed.

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 one parameter (project_id) at 0% schema description coverage, and the description adds no semantics for it. The name is largely self-explanatory and it is the only input, so the gap is minor rather than crippling.

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 specific verb+resource ('Start a paid content optimizer run') that is distinguishable from sibling optimizer tools like get_optimizer_settings or optimize_content_draft. It doesn't explicitly name which sibling it should not be confused with, so it falls short of a 5, but the purpose is unambiguous.

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 when-to-use guidance: nothing says when a paid optimizer run is preferable to optimize_content_draft, list_optimizer_suggestions, or the settings tools. The only conditional information offered is the permission prerequisite, which is about authorization rather than usage routing.

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