e2b_pause_sandbox

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

With no annotations provided, the description carries full responsibility for disclosing side effects. It states only "pause... resumed later" but does not explain whether the sandbox is snapshotted, whether running processes are affected, or what resource/state impact a paused sandbox has.

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 one short, front-loaded sentence with no filler or repetition of the tool name. Every word contributes to the core meaning.

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?

This is a state-changing operation with no annotations and no output schema, so the behavioral context matters. A single sentence does not fully inform the agent about side effects, cold-boot differences, or failure conditions, even though the memory parameter is partially documented in the 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?

Schema description coverage is 50%, and the description adds no parameter-level value beyond that. The memory parameter is well explained in the input schema, but the required sandboxId lacks description in both the schema and the tool description, and the description does not compensate.

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 gives a specific action (pause), a resource (sandbox), and an outcome (resume later). It is clear and does not get confused with destructive siblings like e2b_delete_sandbox or state queries like e2b_list_sandboxes_v2.

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 phrase "running sandbox" implies a prerequisite and "so it can be resumed later" implies a preservation-focused intent. However, it does not explicitly state when not to use it or how it compares with related operations like setting a timeout or deleting the sandbox.

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