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

Without annotations, the description must fully disclose behavioral traits. It notes destructive actions require confirmation, which is good. However, it does not explain other behavioral aspects like idempotency, rate limits, or whether read operations are safe. It provides action signatures but not behavioral consequences beyond 'destructive.'

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 highly structured with categories (Read:, Write:, Destructive:) and concise parameter signatures. It is front-loaded with the purpose. However, it is relatively long and could be streamlined for quicker parsing by an agent. It earns a 4 for good structure but loses a point for verbosity.

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 description provides a comprehensive list of actions and their parameters, covering all operations. However, it lacks information about return values (no output schema), prerequisites (e.g., user permissions), and error handling. For a tool with many sub-actions, the agent needs more context on expected outcomes and failure cases.

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?

The input schema only defines action and params generically. The description compensates by explicitly listing each action's parameters with optionality indicators (e.g., display_name?, time_zone?), providing crucial semantic detail beyond the schema's sparse descriptions. This significantly aids parameter selection.

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 opens with 'GA4 property administration,' immediately conveying the tool's domain. It then enumerates specific actions (list, create, update, delete) with parameter signatures, clearly distinguishing read, write, and destructive operations. This provides high clarity and differentiates it from sibling tools like get_account_summaries or run_realtime_report.

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 includes a usage hint for destructive actions ('requires confirm:true'), but it does not provide explicit guidance on when to use this tool instead of sibling tools like get_property_details or run_report. It implies use for administration tasks but lacks comparative context.

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