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

The description discloses behavioral traits such as creating a draft event (write operation) and the need for permission checks. It does not contradict annotations (readOnlyHint=false). It adds context about business restrictions beyond what annotations provide, though it omits details on side effects or error handling.

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 moderately concise and well-structured, with each sentence contributing value. However, it has slight redundancy (e.g., 'before offering this action' and 'before collecting inputs'). The critical information is front-loaded.

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?

Given the high complexity (29 parameters, nested objects, no output schema), the description is incomplete. It focuses heavily on preconditions but fails to document the parameter semantics, return values, or the draft event structure. The agent lacks necessary details to use the tool correctly.

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 description does not explain any of the 29 parameters. It only provides high-level context about the tool's purpose. The agent is left without guidance on how to use the parameters, making it difficult to construct a valid request.

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 clearly states the action ('create'), the resource ('draft event'), and the context ('for a community managed by the authenticated Nas.com user'). It distinguishes from sibling tools like 'publish_event' by specifying 'draft' and outlines critical prerequisites.

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 provides explicit guidance on when to use this tool: it requires checking business permissions via 'check_business_tool_access', warns that FREE businesses cannot use it, and instructs to show grace-period warnings and never proceed when access is blocked. It names a specific sibling tool to call first.

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