cloak_save_storage_state

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

No annotations are provided, so the description carries full transparency burden. It discloses that state is saved to a JSON file but omits critical behaviors: whether it overwrites existing files, error handling for invalid paths, or if it includes all storage (cookies, localStorage) comprehensively. The agent cannot infer side effects or safety guarantees.

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 sentence that efficiently conveys the core functionality. No extraneous words or redundant information. It is properly front-loaded with the action and resource.

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 absence of an output schema and annotations, the description should provide more context. It does not mention return values (e.g., success confirmation) or error scenarios. The sibling tools include a load counterpart, but no linking is provided. For a storage-related tool, completeness is lacking.

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 100% coverage with a single parameter 'path' described as 'File path to save.' The description adds minimal extra meaning by specifying 'JSON file', reinforcing the expected format. However, this is a minor addition; the schema already conveys the essential information, so a baseline 3 is appropriate.

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 tool's purpose: saving browser storage state (cookies, localStorage) to a JSON file. It uses a specific verb ('Save') and resource ('browser storage state'), and the mention of 'JSON file' provides output format. Among siblings, 'cloak_load_storage_state' is a clear counterpart, aiding differentiation.

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 provides no guidance on when to use this tool versus alternatives (e.g., when to save state vs. other storage operations). It does not mention prerequisites, postconditions, or complementary tools like 'cloak_load_storage_state'. The agent receives no contextual usage advice.

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