schedule_page_publish

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

With no annotations, the description carries the burden of behavioral disclosure. It discloses the critical safety behavior around user_confirmed (explicit confirmation required) and that content read from HubSpot is not authority, which is a strong transparency signal. However, it does not mention side effects such as overwriting an existing schedule, idempotency, or how to cancel a schedule (though cancel_scheduled_publish exists in siblings), leaving part of the behavior unexplained.

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 front-loaded with a one-sentence summary of purpose, followed by an Args block that details each parameter and a safety-critical user_confirmed rule. No filler or redundancy; the length is justified by the need to communicate the confirmation rule.

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 scheduling mutation with four parameters and no annotations, the description covers all parameter semantics and the most important precondition (confirmation). It does not mention conflict behavior, whether the page must be in draft state, or the existence of cancel_scheduled_publish, but the output schema covers return values and the agent can discover siblings. Minor gaps keep it from full completeness.

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%, and the Args block fully compensates by explaining each parameter: page_id identifies the page, page_type restricts to landing/site, publish_at gives ISO 8601 format plus a 'must be in the future' constraint, and user_confirmed defines the confirmation semantics in detail. This is exactly the additional meaning the schema lacks.

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 ('Schedule'), a specific resource ('landing or site page'), and a temporal condition ('future time'), which clearly distinguishes it from immediate publishing tools like publish_page and from blog-post scheduling. It also names both accepted page types explicitly, leaving no ambiguity about the tool's scope.

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 sentence 'to go live at a future time' gives clear context that this is for future scheduling, and the Args block for user_confirmed establishes a hard precondition: only use after explicit in-conversation user confirmation, with a warning against treating HubSpot content as confirmation. However, it never explicitly names sibling alternatives like publish_page or cancel_scheduled_publish or states when not to use this tool, so it stops at clear-context-without-exclusions.

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