browser_sessionstorage_remove

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states the action without explaining edge cases (e.g., what happens if the key doesn't exist) or side effects.

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 very short (5 words), which is concise, but it omits necessary context. Brevity is maintained but at the cost of informativeness.

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 existence of an output schema and multiple sibling tools, the description is insufficient. It does not mention that the tool operates within a specific browser session (via session_id) or how it differs from clearing all session storage.

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%, and the description provides no explanation for the 'key' or 'session_id' parameters. Users cannot understand the meaning or usage of these parameters from the description alone.

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 'Remove a sessionStorage key.' clearly states the action (remove) and the resource (sessionStorage key). It is specific and distinguishes from siblings like browser_sessionstorage_clear (removes all) and browser_sessionstorage_set (sets a value).

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 vs alternatives like browser_sessionstorage_clear or browser_sessionstorage_set. The description does not specify any context or exclusions.

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