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

No annotations are provided, so the description carries the burden; it does disclose the operational workflow (pre-check with list_browsers, re-check after), which is useful behavioral context. However, it does not say whether the call is idempotent, how long provisioning takes or whether the agent must wait, what happens if a runner already exists, or whether licensing/session setup is required first.

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?

Two compact sentences, front-loaded with the action, then the trigger and follow-up step. Every clause carries operational information; nothing is redundant.

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 lifecycle/provisioning tool with no annotations and no output schema, the definition covers the trigger and the verification step but leaves the agent unsure what 'prepare' entails, how long it takes, and how to recognize success or failure. Adequate to invoke, not adequate to handle the outcome.

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 100% and the single optional parameter is fully documented in the schema, so the baseline of 3 applies. The description adds nothing about notification_message, but it doesn't need to.

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?

Names a specific action (start/prepare) and a specific resource (Nova remote BrowserGPT runner), and ties it to the underlying command name so the agent can map it to known behavior. It is clearly distinguishable from the browser_* siblings and from list_browsers, though 'prepare' remains somewhat fuzzy about what actually gets provisioned.

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?

Gives an explicit trigger condition ('when list_browsers shows no online+ready remote node') and the required follow-up ('then list_browsers again'), which is exactly what an agent needs to sequence this tool. No when-not conditions or failure handling are stated, keeping it short of a 5.

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