browser_localstorage_remove

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

No annotations are provided, so the description must fully disclose behavior. It only states removal but does not mention error handling when key is missing, side effects, or the role of session_id. The removal action implies irreversibility but this is not explicit.

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 short sentence, but it sacrifices informative content for brevity. It is under-specified rather than concisely comprehensive.

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 annotations, low schema coverage, and a required parameter, the description fails to provide sufficient context. It does not explain the output, prerequisites, or behavioral nuances like session isolation.

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 0%, meaning the schema lacks parameter descriptions. The tool description adds nothing about the 'key' parameter or the optional 'session_id'. The agent must infer meaning solely from parameter names and titles.

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 ('Remove') and resource ('localStorage key'). It distinguishes from siblings like browser_localstorage_clear (which removes all keys) through the verb 'remove' vs 'clear' and the explicit mention of 'a key'. However, it could be more specific about removing a single key.

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 on when to use this tool versus alternatives like browser_localstorage_clear, browser_localstorage_set, or browser_sessionstorage_remove. The description simply states the action without context or exclusions.

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