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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the bulk execution behavior, but does not disclose pagination, return format, or how project_id and project_ids relate. No contradiction with annotations.

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 core purpose. However, 'Retrieves a list of snapshots for a Studio project' largely restates 'List Studio Project Snapshots,' creating minor redundancy. The bulk support sentence adds useful information.

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 simple read-only list tool with strong annotations, the description covers the basic operation and bulk capability. However, with no output schema, it does not describe return values, pagination, or how the optional account parameter and project_ids interact with the required project_id.

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%, so the description must compensate for parameter semantics. It only explains project_ids as 'batched execution'; the required project_id and optional account parameters are not described, and the relationship between project_id and project_ids is unclear.

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 opens with 'List Studio Project Snapshots,' which is a specific verb+resource statement. It clearly distinguishes this tool from sibling chapter snapshot tools and the singular project snapshot endpoint by indicating plural list retrieval.

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 'Bulk support: accepts project_ids for batched execution' note provides some usage context for the bulk parameter. However, the description does not explicitly state when to prefer this tool over alternatives like elevenlabs_get_project_snapshot_endpoint or elevenlabs_get_chapter_snapshots.

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