Auto-configure external analytics

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

Annotations already indicate idempotentHint=true and destructiveHint=false. The description adds context that the tool derives settings from existing tracking and errors if none exist, which are important behavioral traits. No contradiction with annotations.

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 sentence that is clear and front-loaded, containing the core purpose and key constraints. However, it lacks parameter explanation, though this is partly compensated by the brevity.

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 simple tool with one parameter, no output schema, and good annotations, the description covers the main purpose and error condition. However, missing parameter documentation and lack of explicit usage context (e.g., when to use vs. set_analytics_config) leave some gaps.

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 has a single required parameter 'project' with no description (0% schema coverage). The description does not explain what 'project' is or its format, leaving the agent to guess. Since the description fails to add any meaning beyond the schema, this dimension scores low.

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 verb 'Derive the external analytics read config from the site's existing tracking settings' and mentions enabling the proxy. It distinguishes the tool from siblings like 'set_analytics_config' by automating configuration based on existing settings.

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 explains when to use the tool: to avoid retyping the domain/property. It also states an error condition when no analytics are configured, implying it should not be used in that case. However, it does not explicitly name alternative tools such as 'set_analytics_config' for manual configuration.

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