iptime_apply_change

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

It adds meaningful behavioral guardrails beyond the annotations: 'exactly one' plan is applied, and the confirmation text must be repeated verbatim. This is important for a destructive, non-idempotent operation, though it does not describe post-apply effects.

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?

A single sentence with no filler. It front-loads the action, resource, and constraint, making it quick for an agent to parse and 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?

The essential contract is stated, but for a destructive, open-world operation with no output schema, it omits what happens on success or failure and any prerequisite context such as how plans are created or confirmed.

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 0%, so the description must compensate. It succeeds in explaining that 'confirmation' is the verbatim text to repeat and implies 'plan_id' identifies the pending plan. It does not fully explain how to obtain the confirmation text, but the core semantics are present.

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 a specific verb ('Apply') and resource ('pending plan'), and clarifies the exact condition: it applies only one plan after verbatim confirmation. This distinguishes it from sibling tools like iptime_plan_change, iptime_cancel_change, and iptime_list_plans.

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 implies when to use the tool—when a pending plan exists and its confirmation text is available—but it does not explicitly mention alternatives or conditions where the tool should not be used.

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