snapshot_buffer

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

The description implies a non-destructive save operation and the ability to revert, which gives basic transparency. However, it does not disclose whether snapshots are overwritten, if there are limits, or any permissions needed. With no annotations, the description carries the full burden but only partially fulfills it.

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 short sentence, making it concise and front-loaded. However, it is somewhat terse and could include a bit more detail (e.g., about the label parameter) without becoming verbose.

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 presence of an output schema reduces the burden on the description for return values. Given the tool's simplicity and the existence of sibling tools for similar actions, the description provides adequate context but could be more explicit about the snapshot lifecycle (e.g., how to revert and list snapshots).

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 input schema has one optional 'label' parameter with a default, but the description does not mention it at all. Given 0% schema coverage in the description, it adds no meaning beyond the schema itself. The parameter is optional, so some guidance on when to provide a label would improve this score.

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 tool saves a snapshot of the working buffer for later reverting. It uses a specific verb-resource pair ('save a snapshot') and conveys the purpose ('revert later'), but does not differentiate from similar sibling tools like 'save_buffer'.

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?

No guidance is provided on when to use this tool versus alternatives. For example, it does not mention that it is for temporary undo points compared to permanent saves, nor does it give any prerequisites or edge cases.

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