flutter_core_did_send_first_frame_rasterized_event

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. While 'Check' implies a read-only operation, it doesn't specify whether this is a one-time check, a polling mechanism, or what happens if the first frame hasn't been rasterized yet. It doesn't mention authentication needs, rate limits, or what the response format might be. For a tool with zero annotation coverage, this leaves significant behavioral questions unanswered.

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 extremely concise at just 7 words, front-loading the core purpose without any wasted words. Every word earns its place by specifying it's an RPC call and what it checks. The structure is optimal for quick comprehension.

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's complexity (checking a specific Flutter debugging event), lack of annotations, and no output schema, the description is insufficiently complete. It doesn't explain what 'rasterized' means in this context, what the return value indicates (boolean? status object?), or how this integrates with Flutter's debugging workflow. For a specialized debugging tool, more context would be helpful.

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 input schema has 100% description coverage, with the single parameter 'port' clearly documented in the schema. The description adds no additional parameter information beyond what's already in the schema. With complete schema coverage, the baseline score of 3 is appropriate as the description doesn't need to compensate for schema gaps.

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 the tool's purpose as 'Check if the first frame has been rasterized', which is a clear verb+action. However, it doesn't distinguish this tool from its sibling 'flutter_core_did_send_first_frame_event', which appears to check a similar event but without the 'rasterized' qualifier. The description is specific about what it checks but doesn't clarify the distinction between these two frame-related events.

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. It doesn't mention when this check is appropriate during Flutter app debugging, what triggers the first frame rasterization event, or how it differs from the sibling 'flutter_core_did_send_first_frame_event'. There's no context about prerequisites or typical use cases.

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