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 effectively describes the tool's actions (stopping the browser and cleaning up the sandbox) and the outcome (freeing up resources), which are critical for understanding this destructive operation. However, it doesn't mention potential side effects like losing unsaved data or session state.

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 perfectly concise with two sentences that each earn their place: the first states the action and resource, the second provides usage guidance. It's front-loaded with the core purpose and wastes no 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?

Given the tool's simplicity (0 parameters, has output schema), the description is complete. It explains what the tool does, when to use it, and the outcome, which is sufficient for a cleanup operation. The output schema will handle return values, so no need to describe them here.

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, so the baseline is 4. The description appropriately doesn't discuss parameters, as none exist, and instead focuses on the tool's purpose and usage context.

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 tool's purpose with specific verbs ('stop', 'clean up') and identifies the resource ('browser', 'Daytona sandbox'). It distinguishes itself from sibling tools like browser_start, browser_status, and browser_close_tab by focusing on termination and cleanup rather than initialization, monitoring, or tab management.

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 provides explicit guidance on when to use this tool ('Call this when you're done using the browser') and implicitly suggests alternatives (e.g., use other browser tools while active, avoid calling prematurely). This clearly differentiates it from siblings that perform actions during browser usage.

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