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

With no annotations provided, the description carries the full burden. It does disclose a key behavioral trait: the inclusion of 'safety approval gates'. It also hints at a coupling with runtime tools. However, it omits details like error behavior, permission/authentication requirements, or whether the execution is idempotent, which would be valuable for a planning/mutation tool.

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 sentences, each earning its place. The first states the core action and output; the second situates the tool in the broader ecosystem. No fluff, no repetition of schema-visible information, and front-loaded verb leads.

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 tool with 2 parameters, high schema coverage, and no annotations or output schema, the description covers the essentials—purpose, output medium, safety posture, and integration context. Still, for a safety-relevant agent that handles OS-level automation, a sentence on scope or expected usage flow would improve completeness.

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%, so this is a baseline 3. The description does add slight value by clarifying the OS-specific output context (cliclick/xdotool/PowerShell), which implicitly relates to the 'language' parameter's potential targets, but it does not go beyond what a well-documented schema already communicates.

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 uses specific verbs ('Plan', 'emit') and a clear resource ('GUI / computer-use task', 'OS-specific step scripts'), naming concrete technologies (cliclick / xdotool / PowerShell). It further distinguishes itself from the large sibling list by noting it 'Pairs with the runtime computer_use tools', which is a clear differentiation point.

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 when to use the tool: whenever a GUI/computer-use task must be planned and scripted. However, there is no explicit 'use when', 'not for', or named alternatives, which is notable given the enormous sibling list of specialized agents. The guidance is functional but relies on inference.

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