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

The description discloses a meaningful behavioral trait (cascading deletion of language targets) and bulk support, which goes beyond the sparse annotations. However, annotations declare destructiveHint: false even though deletion is inherently destructive, and the description does not address irreversibility, permissions, or batch execution consequences. It adds some value but leaves ambiguity regarding destructive semantics.

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 short and front-loaded with the main action, followed by a specific scope clarification and a bulk-support note. Every sentence earns its place, though the bulk support line could have included more parameter detail.

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?

For a delete operation with no output schema, no annotations beyond hints, and 0% schema coverage, the description should explain return behavior, error cases, and idempotency. It covers the core deletion and bulk aspect but is incomplete for an agent to confidently invoke it, especially given the destructive nature and sibling overlap.

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?

With schema description coverage at 0% and no parameter-level descriptions, the description must compensate, but it only mentions 'project_ids' for bulk support and implies 'project_id' via the delete action. The 'account' parameter is entirely unexplained, and the distinction between project_id and project_ids is not clarified beyond the bulk note.

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 states a specific verb ('Delete') and resource ('Dubbing Project'), clarifying it deletes a project and its language targets. It partially distinguishes from siblings like elevenlabs_delete_project by focusing on dubbing projects, though it shares the same generic delete action with many siblings.

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 when to use it—for deleting dubbing projects and their language targets—but does not explicitly contrast it with alternative delete tools like elevenlabs_delete_project or elevenlabs_delete_dubbing. The bulk support note adds a usage context, but no explicit when-not or alternative guidance is provided.

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