snapshot_create

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

With no annotations, the description carries full responsibility for behavioral transparency. It explains how snapshots capture state and that the returned path is used for binding, but does not mention side effects, error conditions, permissions, or idempotency. The description is informative about the snapshot mechanism but incomplete regarding creation-specific behavior.

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 concise and well-structured, starting with a clear one-line purpose, then elaborating with context. It avoids unnecessary jargon and stays focused, though the second sentence partially repeats the first. Overall, it is efficient without being overly terse.

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?

The description provides solid conceptual context for snapshots and hints at the return path, which is helpful. However, it omits potential edge cases (e.g., duplicate names, behavior on failure) and does not clarify if the operation has any prerequisites. For a simple create operation, it is reasonably complete but leaves some gaps.

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?

The schema provides only 'name' with no description, and the tool description adds only 'Snapshot name.' This offers minimal additional meaning beyond the parameter label, lacking details on constraints, uniqueness, or format. The description does not meaningfully compensate for the sparse schema.

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 'Create a mixer snapshot' and explains the concept of a snapshot as capturing mixer state changes. It distinguishes this creation action from other snapshot operations (list, info, rename, delete, bind) by focusing on the act of creation.

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 this tool (when you need a new snapshot) but does not explicitly mention alternatives or contrast with other snapshot functions. It does reference the complementary snapshot_bind_group, which provides some guidance, but lacks explicit 'use when' or 'instead of' statements.

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