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

With no annotations provided, the description carries full burden. It discloses the action ('Close'), resource release, and return value format ('dict with status "closed"'), covering key behavioral aspects. However, it doesn't mention side effects like terminating sessions or cleanup behavior.

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 front-loaded with the core action, followed by return value details. Both sentences earn their place: the first defines the action and resource release, the second specifies the return format. No wasted words.

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 0-parameter tool with no annotations or output schema, the description is mostly complete: it states the action, resource release, and return format. However, it could add more context like cleanup implications or prerequisites (e.g., browser must be launched).

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 0 parameters with 100% schema description coverage. The description doesn't need to explain parameters, and it appropriately doesn't add unnecessary details. Baseline is 4 for 0 parameters.

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 specific action ('Close') and resource ('the Camoufox browser'), distinguishing it from sibling tools like 'launch_browser' or 'reload'. It explicitly mentions 'release all resources', which adds specificity beyond just closing.

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 implies usage when needing to close the browser, but doesn't explicitly state when to use it versus alternatives (e.g., 'navigate' or 'reload' for other actions). It lacks explicit exclusions or comparisons to sibling tools.

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