snapshot_list

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

With no annotations, the description itself conveys a read-only behavior through the verb 'List.' It does not explicitly mention side effects or empty-result behavior, but the non-mutating intent is clear.

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 clear sentence with no filler, repetition, or unnecessary 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 zero-parameter list tool, the description is largely complete: it names the action, object, and scope. It does not describe the output format (e.g., names, metadata, timestamps), but this is reasonably inferred from 'list' and the absence of an output schema.

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 tool has no parameters and the input schema is empty, so there are no parameter semantics to clarify. The description adds no unnecessary parameter-related detail.

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 ('List'), the object ('saved snapshots'), and the scope ('in this session'), leaving no ambiguity about the tool's purpose.

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 makes the basic use case obvious, but it does not explicitly guide when to use this tool versus snapshot_save or snapshot_recall. A brief note about using it to review snapshots before recall or save would strengthen guidance.

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