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

No annotations are present, so the description carries full behavioral burden. It discloses that the action is 'irreversible' and requires 'explicit user approval', which are important safety traits. However, it does not mention that this is a destructive mutation, potential side effects, required permissions, or what happens on success/failure. The irreversibility is valuable but not sufficient for full transparency.

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, efficient sentence that front-loads the core action and its irreversibility. It avoids unnecessary words and is well-structured. It earns a high score for conciseness, though it could be slightly more informative without sacrificing 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?

Given no annotations, no output schema, and incomplete parameter descriptions, the description leaves out critical context: what a draft is, how to create or obtain it, the confirm workflow (prepare/confirm), expected response or receipt, and any caveats. For an irreversible action, this is insufficient for an agent to invoke it correctly and safely.

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 50% (customer_id has a description, draft_id does not). The description adds no parameter-specific meaning beyond the schema. It doesn't clarify what draft_id refers to, how to obtain it, or its relationship to the prepare step. With moderate coverage, the description should compensate but does not.

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 action: 'Confirm one irreversible entity-removal draft'. It names the verb (Confirm), the resource (entity-removal draft), and a key trait (irreversible). It is distinguishable from siblings like 'google_ads_entity_remove_prepare' and other confirm tools by explicitly focusing on removal confirmation. However, it doesn't explicitly contrast with the prepare counterpart or other removal confirm tools, which slightly weakens differentiation.

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 implies usage context via 'after explicit user approval', indicating it should only be invoked post-approval. But it provides no explicit guidance on when to use this vs. other tools, no mention of the prerequisite prepare step, and no exclusions. For a confirm operation that likely pairs with a prepare step, this is a significant omission.

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