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

With no annotations, the description is the sole source of behavioral info. It lists four distinct actions but provides no mechanism to specify which one, which contradicts the empty input schema. This omission leaves the agent unable to correctly invoke the tool.

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 very short (one sentence), which is concise, but it tries to pack multiple actions without structure. It lacks front-loading of the core function and could be more effective.

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?

Given no annotations, no output schema, and an empty input schema, the description is severely incomplete. It does not explain how to specify actions, what inputs are required, or what the return values look like, leaving the agent underinformed.

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 has 0 parameters (100% coverage, empty). The description implies parameters are needed (e.g., action type) but doesn't define them, creating confusion. Baseline of 4 for no params is reduced due to misleading implications.

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 states 'Workspace snapshots' and lists actions (create, restore, list, delete), but fails to specify which action is performed upon tool invocation. The lack of parameters in the input schema makes the action selection ambiguous, reducing clarity.

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 siblings like 'search' or 'exec'. The description does not explain under what circumstances snapshot management is appropriate, nor does it mention alternatives.

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