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

The description reveals billing implications ('charged like a generation') and conflict behavior ('Conflicts when the target has no edits to apply are ignored'). But annotations state destructiveHint=false while the description implies destructive replacement ('re-dub', 're-synthesizing') of the target dub, which is a contradiction in behavioral disclosure.

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 brief and front-loaded with the core purpose ('Regenerate Dubbing Target'), then adds caveats (enterprise-only, billing, conflicts). The two-paragraph structure is scannable and no fluff. Could be slightly more structured with explicit param headings.

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's complexity (mutating, enterprise-only, billing repercussions, conflict errors, bulk support) and minimal schema descriptions, the description should be richer: it's missing required enterprise prerequisites, auth requirements, the exact failure modes beyond 'no edits', and the relationship to the underlying transcript edits. Merely noting enterprise-only and a conflict case is insufficient for safe and correct use.

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 description coverage is 0% (all 3 params undocumented). Description partially compensates by explaining that project_ids and language_ids support bulk executionags, but it never explains their individual meaning, types, or how single vs. bulk modes are determined, so agents lack critical parameter guidance.

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 (

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 provides limited usage context: 'Enterprise only' and 'Bulk support' with project_ids/language_ids, plus a conflict condition (no edits → no dispatch/charge). However, it doesn't offer guidance on when to choose this over sibling tools such as update/delete/get transcript, or explain prerequisites for re-dubbing.

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