restore_session

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

No annotations are provided, so the description carries the full burden. It discloses that the operation restores a disk session into active memory, but it does not mention whether the current session is overwritten, whether unsaved work is at risk, or how invalid IDs are handled.

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?

Two short sentences, with the action stated first and the prerequisite lookup second. There is no filler and every sentence earns its place.

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 tool is simple with one required parameter and has an output schema to cover return values. The description covers the core action and how to find a valid ID, but omits state-change risks such as overwriting the active session, which would be helpful for safe invocation.

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 only declares session_id as a required string with no description, and coverage is 0%. The description partially compensates by telling the agent to call list_sessions to obtain valid saved session IDs, but it does not explain ID format or error behavior.

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 uses a specific verb ('restore') with a clear resource ('saved disk session') and target state ('active memory'). It also references list_sessions, which distinguishes this session-restoration tool from dataset-loading siblings like load_dataset.

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?

It provides a clear precondition: call list_sessions to discover available saved session IDs. It does not explicitly discuss when not to use the tool or compare it against alternatives, so it stops short of a full usage-guide, but the context is clear.

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