v0.10.26Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry behavioral disclosure. It reveals the background Win32 message mechanism, which is useful context, but does not describe whether actions are destructive, what permissions are needed, what happens on failure, or what state changes occur.
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 a single front-loaded sentence with no filler, so it is concise. However, it is so terse that it omits essential structure and detail for a 7-parameter tool.
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?
The tool has 7 parameters with no schema descriptions, no annotations, and many sibling GUI tools. The one-sentence description provides no parameter meanings, no usage context, and no behavioral detail, making it wholly inadequate for correct invocation.
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 0% and the description explains none of the 7 parameters. It does not clarify the valid values for 'action', the role of 'handle', 'control_id', 'class_name', 'window_title', 'text', or 'title'.
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 says it will 'Act on a Rohitab GUI control' but 'Act' is a vague verb that does not specify what operations are possible. It does not distinguish this tool from the many sibling GUI tools such as api_monitor_gui_click_point, api_monitor_gui_key, api_monitor_gui_select, or api_monitor_window_control.
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?
There is no guidance about when to use this tool versus the numerous other GUI-related tools. The phrase 'using background Win32 messages' hints at a mechanism but does not explain when that mechanism is preferred or what alternatives exist.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
