createBudgetSchedule

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only restates that the tool 'creates' a schedule. It does not mention side effects, whether the schedule replaces an existing one, idempotency, validation constraints, or what happens on conflict.

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?

The description is a single clear sentence with no redundant flufftons. It is front-loaded with the core action and resource, but 'specific time window' is somewhat vague and could be more precise without adding length.

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 mutation tool with five required parameters, no annotations, and no output schema, the description is too sparse. It omits behavioral context, return value expectations, and parameter constraints such as timeStart needing to precede timeEnd, making it insufficient for confident 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 all five parameters already have semantic descriptions in the schema. The tool description only adds the vague phrase 'specific time window', which loosely maps to timeStart/timeEnd but provides no additional meaning beyond what the schema already states.

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 the action 'Create' and the resource 'budget schedule for a campaign', which is distinct from the sibling tools like updateCampaign or pauseCampaign. It adds 'with a specific time window', giving some scope. However, it does not explicitly differentiate from closely related budget operations or explain what a budget schedule entails.

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 alternatives such as updateCampaign or cloneCampaign. No prerequisites, conditions, or exclusions are mentioned, leaving the agent to infer appropriate usage solely from the tool name.

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