ga4_delete_measurement_protocol_secret

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It adds useful context by stating the prerequisite checks and that deletion revokes the secret. However, it does not disclose potential side effects, required permissions, or the irreversible nature of the operation, which would be valuable for a destructive action.

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 exceptionally concise: two short sentences that front-load the tool type and action, then state prerequisites. Every sentence earns its place with no redundant content.

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 tool is a delete operation with no output schema, the description adequately covers the action and prerequisites. However, it could be more complete by mentioning that the operation is irreversible or that the name parameter must follow the correct format, though the schema already describes the name format. The lack of sibling differentiation beyond the resource name is a minor gap.

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 100% coverage with descriptions for both parameters. The description does not add meaning beyond the schema; it only repeats that 'confirm' must be true, which is already in the schema as a required boolean. Thus, no additional value is provided, meeting the baseline score.

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 that the tool deletes a Measurement Protocol secret and revokes it. The '[GA4 DELETE]' prefix helps categorize, and the verb 'Delete' with the resource 'Measurement Protocol secret' is specific and distinguishes it from sibling tools that delete other GA4 resources.

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 explicitly mentions prerequisites: 'Requires GA4_MCP_ENABLE_DELETES=true and confirm=true.' This provides clear context on when to use the tool. However, it does not suggest alternatives or explicitly state when not to use it, though the conditions imply it should only be used when deletion is intended and enabled.

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