Browser Network Unblock

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does disclose the broad 'all' scope, signaling this is a sweeping destructive action on every blocking rule, which is important context. However, it does not mention reversibility, whether in-flight requests are affected, or whether the action is idempotent.

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?

A single six-word sentence with zero filler. Every word earns its place, and the scoping qualifier 'all' is front-loaded where it matters most.

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?

For a parameterless tool with an output schema present, the description is nearly complete. An agent can correctly invoke it with no arguments. The only gap is the absence of any note about side effects or scope consequences beyond 'all,' which is a minor omission given the tool's simplicity.

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 tool has zero parameters with 100% schema coverage, so the schema documents everything there is to know. Per the rubric, a zero-parameter tool earns a baseline of 4; the description correctly adds no parameter noise since none exist.

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 all URL blocking rules' states a specific verb (remove) and resource (URL blocking rules), making the purpose immediately clear. It pairs naturally with the sibling browser_network_block as its inverse, though it does not explicitly name that counterpart.

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 gives no guidance on when to use this tool versus alternatives, no exclusions, and no mention of preconditions. Usage is only implied as the natural undo for browser_network_block, which an agent would have to infer from the sibling list rather than from the description itself.

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