A4.4/5.0

Behavior5/5

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

Annotations declare non-read-only and non-destructive, but the description adds critical context beyond them: it saves a private draft, runs Google validate-only, captures a full affected-resource snapshot, and does NOT send the change. This draft/validation semantics is exactly the behavioral nuance the agent needs and cannot get from annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the purpose, followed by the draft behavior and the confirmation handoff. No filler; each sentence carries distinct information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values needn't be explained, and the description fully covers the draft lifecycle and confirmation requirement. The only shortfall is the absence of parameter guidance for the nested body fields, which matters given the low schema coverage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33% — customer_id is documented but body's nested campaign_id/geo_target_id and connection_context have no descriptions. The description does not compensate: it never explains what geo_target_id is (a canonical geo target constant vs. free text) or how to obtain one, leaving a meaningful gap for a geo-exclusion operation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('exclude a geographic target from a campaign') and explicitly distinguishes the prepare phase from the confirm phase by naming the sibling. An agent can immediately tell what this tool does and what it does not do.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names the follow-up tool (google_ads_negative_location_add_confirm) and states the precondition that execution requires the user's agreement in the conversation. Covers when to use this versus the confirm sibling with no inference required.

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