import_state

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

The description reveals that a new context is created, but lacks details on side effects (e.g., what happens to existing contexts, whether the import overrides any existing state). No annotations are provided, so the description carries the full burden.

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 brief and covers the essential information: purpose, argument, and return value. It could be slightly more concise, but it is well-structured with clear sections.

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 the simplicity of the tool (one parameter, no output schema), the description provides adequate information to understand basic usage. However, it lacks details on error handling, expected behavior when the file is invalid, or interaction with the current browser state.

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 with no description, but the description adds context: state_path is a path to a JSON file exported by export_state. This adds meaning beyond the schema type and title.

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: importing browser state from a JSON file by creating a new context. It distinguishes itself from sibling tools like export_state and reset_browser_state.

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 implies usage after export_state to restore state, but does not provide explicit guidance on when to use this tool versus alternatives like reset_browser_state, nor does it mention any prerequisites or context state requirements.

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