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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states what the tool returns, without mentioning whether this is a read-only operation, if it requires specific permissions, what format the messages come in, or any rate limits. For a tool with no annotation coverage, this is insufficient behavioral context.

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 appropriately sized with a clear purpose statement followed by parameter details. The two-sentence structure is efficient, though the parameter explanation could be slightly more concise. Every sentence adds value without redundancy.

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?

Given the tool has an output schema (which handles return values) and only one parameter with description coverage, the description is minimally adequate. However, for a tool with no annotations and siblings offering various diagnostic functions, it should provide more context about when this specific console message retrieval is appropriate versus other debugging options.

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 description adds meaningful context for the single parameter 'level', explaining that 'Each level includes the messages of more severe levels' and providing the default value. With 0% schema description coverage and only one parameter, this compensation is effective, though it doesn't specify what the valid level values are (e.g., 'info', 'warning', 'error').

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's purpose with 'Returns all console messages', specifying the verb 'returns' and resource 'console messages'. It distinguishes from siblings like qt_screenshot or qt_click by focusing on console data retrieval rather than UI interaction or screenshots. However, it doesn't explicitly contrast with all siblings, keeping it at 4 instead of 5.

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 provides no guidance on when to use this tool versus alternatives. With siblings like qt_snapshot or qt_widget_details that might also return diagnostic information, there's no indication of when console messages are preferred over other debugging tools. The parameter explanation doesn't substitute for usage context.

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