qt_call_method

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

No annotations exist, so the description carries the full burden. It discloses critical behavioral traits: destructive with no undo, methods execute for real, deleteLater destroys the element and invalidates its id, and args are silently coerced up to 10. This goes beyond the schema and gives essential safety warnings.

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 front-loaded with the core purpose, followed by crucial warnings and usage guidance. It is concise with no wasted words; every sentence provides necessary information.

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?

With an output schema present, return values are covered. The description covers purpose, usage, destructive behavior, and arg constraints. However, it leaves session_id/element_id semantics and failure behavior unexplained, which is a noticeable gap for a 4-parameter tool.

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 descriptions are 0%, so the description must compensate. It adds meaning for method (invokable, dangerous examples) and args (coerced, max 10), but session_id and element_id remain completely undefined. The description does not fully explain the parameters needed for correct invocation.

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 invokes a QMetaObject-invokable method on a UI element, with specific examples (close, deleteLater) and contrasts this with simulating user input. This distinguishes it from sibling input simulation and property tools.

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?

Explicitly advises preferring simulating user input (clicks/keys) and using direct method calls only when a direct API invocation is intended. This provides clear when-not-to-use guidance and names an alternative category (input simulation).

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