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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=true, so the risk profile is carried by structured data. The description adds real value by explaining that all identifying fields must be nested in one body object, but it says nothing about irreversible effects, permissions, or what a failed action means beyond what the annotations cover.

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?

Front-loads the prerequisite call before the payload rules and closes with the single highest-risk mistake ('do NOT pass these as separate parameters'). Slightly heavy formatting (all-caps warning, bullet list) but each sentence addresses a distinct failure mode, so little is wasted.

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?

An output schema exists, so return values need no explanation, and the description covers the sequencing and the flat-object requirement that the schema cannot express. Given the destructive annotation, a sentence on error or partial-failure behavior would complete it, but the essentials for a correct call are present.

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?

Schema coverage is 0% and the single parameter is a free-form object with additionalProperties=true, so the description must carry the meaning — and it does, enumerating required body keys (action, workspace_id, brand_id, location_id) and the source for the remaining fields. It still defers the exact field list to a prior helper call ('any other fields from the helper response'), leaving some ambiguity about which actions need what.

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?

Names a concrete verb and resource ('Execute Google My Business actions') and positions it as the terminal write step in a 3-step workflow, which distinguishes it from the query siblings. The verb 'execute' alone is generic, but the payload hint (action/table name) makes the operation concrete.

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?

Explicitly states the prerequisites: run query_contexts with request='accounts' and request='actions_details' before calling, and labels this 'Step 3 FINAL'. An agent knows exactly what must precede invocation and which sibling does which part, with no inference needed.

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