B3.4/5.0

Behavior3/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the write/irreversible profile is covered. The description adds that callers must supply the complete expected_changes and an expected_plan_digest, hinting at an integrity guard, but it never says what happens on a mismatch, whether the change is applied atomically, or what permissions are needed.

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

Conciseness4/5

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

A single sentence front-loaded with the action verb ('Confirm') and zero filler. Dense but not padded; the only cost is that cramming two alternative paths into one clause makes it slightly demanding to parse.

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

Completeness3/5

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 need no explanation, and the description does cover invocation. For a destructive mutation across 6 parameters with 17% schema coverage, it still omits prerequisites (prepare-first), safety framing, and handling of the optional parameters — meaningful gaps given the blast radius.

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

Parameters3/5

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

Schema description coverage is only 17% (customer_id only), so the description must carry weight; it does explain the two functional groupings of the six parameters, which the schema does not. But connection_context and the internal shape of expected_changes items remain undocumented in both places.

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

Purpose4/5

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

States a specific verb ('Confirm') applied to a specific resource ('a prepared change'), and immediately enumerates the two identifying key combinations. It does not name google_ads_bidding_update_prepare, but 'prepared change' strongly implies the pairing. Clear enough to distinguish from siblings without opening a schema.

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

Usage Guidelines3/5

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

Explains the two alternative parameterization paths (customer_id+draft_id vs. approval_ref+expected_plan_digest+expected_changes), which is real selection guidance. However it never states that a prepare step must precede this call, nor when to prefer one path over the other, leaving the actual 'when to use' implied.

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