qt_invoke_slot

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

No annotations are provided, so the description must carry the full behavioral burden. It says it invokes a slot or method but does not disclose side effects, whether the invocation can be destructive, permission requirements, or what happens if the method has arguments or fails.

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 short and front-loads the core action in the first sentence. The Args section is compact and easy to scan, with no unnecessary prose.

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 an arbitrary QObject method-invocation tool with no annotations and only 0% schema description coverage, the description is too thin. It omits the optional instance parameter, invocation argument behavior, and side-effect expectations, though the output schema reduces the need to explain return values.

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 only explains ref and method_name. The optional instance parameter is completely undocumented, and there is no detail on how method arguments are supplied despite this being an invocation tool.

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 states a specific verb and resource: invoke a slot or method on a QObject. It is clear enough to distinguish from general property setters or signal readers, but it does not explicitly name or contrast with close siblings such as qt_trigger_action or qt_set_property.

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 only usage context is that ref comes from qt_snapshot. There is no guidance on when to choose this tool over qt_trigger_action, qt_set_property, or direct interaction tools, and no exclusions or prerequisites beyond the ref source.

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