Restore snapshot

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

With no annotations, the description carries the full burden. It only discloses that the operation is itself undoable, which is helpful. However, it does not describe what restoration does to the current state, whether it overwrites data, requires specific permissions, or the return value.

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 extremely concise at two sentences. Each sentence adds some value: the first states the action, the second notes undoability. However, the first sentence essentially restates the tool name, so it earns its place only minimally.

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 tool with no annotations and no output schema, the description omits critical contextual information such as the effect of restoration, expected return, and relationship to current model state. This is insufficient for an agent to confidently invoke the tool in varied contexts.

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 has one parameter (snapshotId) with 0% description coverage. The description does not explain the parameter's meaning or format. Although the parameter name is self-explanatory, the description fails to compensate for the lack of schema documentation.

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 'Restore a snapshot' with a specific verb and resource. It does not explicitly distinguish from sibling tools like save_snapshot or undo, but the meaning is apparent. The phrase is somewhat tautological with the tool name, so it is clear but not exemplary.

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 no guidance on when to use restore_snapshot versus alternatives like undo or redo. There is no mention of use cases, prerequisites, or exclusions, leaving the agent without context for tool selection.

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