Behavior2/5

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 only states 'Unlock advanced tools' and lists examples, without detailing side effects, persistence, toggling behavior, or any impact on the system. This is a significant gap for a tool that likely changes the available toolset.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is concise and front-loaded with the action 'Unlock'. It efficiently lists the advanced tools without unnecessary words, making it easy for an agent to grasp the purpose quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, no output schema), the description is largely complete in explaining what it does. It enumerates the unlocked tools. However, it does not clarify the nature of 'unlock' (e.g., UI display vs. feature activation) or mention the opposite action (hide_advanced_tools), which would provide fuller context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, so the baseline is 4 per the rubric. The description does not need to add parameter semantics because there are none, and the schema is empty with 100% coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the verb 'Unlock' and specifies the resource 'advanced tools', followed by a concrete enumeration of capabilities (network interception, request replay, API mocking, etc.). It clearly distinguishes itself from sibling tools like 'hide_advanced_tools' by indicating it is the action to expose these tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies that this tool should be used to gain access to advanced tools, but it does not explicitly state when to use it versus alternatives, nor does it mention any exclusions or prerequisites. The list of tools serves as indirect context, but there is no direct guidance.

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