open_task

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

With no annotations, the description carries the burden of behavioral disclosure. It transparently notes that it directly executes chrome.exe and falls back to the default browser if Chrome isn't installed, and explains why this is necessary. This adds meaningful context beyond a simple 'open' statement, though it omits error handling or prerequisites.

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 two sentences: the first states the primary action and the second provides the rationale. It is concise, front-loaded, and contains no filler, making it easy to parse quickly.

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 simple one-parameter tool, the description covers the core purpose and adds contextual rationale about browser behavior. While it does not mention error handling or prerequisites, the presence of an output schema and the straightforward nature of the operation make this reasonably complete.

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 schema defines task_id as an integer with 0% coverage in the description. The description does not explicitly explain the meaning or format of task_id, relying entirely on the naming convention. Given low schema coverage, the description should have compensated but did not, leaving the parameter's purpose inferred rather than stated.

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 'Opens the task web screen in a new Chrome tab,' using a specific verb and resource. It distinguishes this tool from sibling tools that manipulate task data (e.g., update_task, delete_task) by focusing on launching the UI rather than modifying data.

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 explains why this tool exists—to guarantee opening in Chrome instead of VSCode's built-in browser—which provides clear context for when to use it. However, it does not explicitly name alternative tools or state when not to use this one, making the guidance implicit rather than explicit.

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