flutter_core_profile_platform_channels

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool's purpose but doesn't explain what 'profiling of platform channels' entails, whether this requires specific permissions, if changes are persistent, what side effects might occur, or what the expected response looks like. For a tool that likely modifies runtime behavior, this is insufficient transparency.

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, efficient sentence that directly states the tool's purpose with zero wasted words. It's appropriately sized for a simple toggle tool and is front-loaded with the essential 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?

Given the tool's moderate complexity (controlling runtime profiling), lack of annotations, and no output schema, the description is minimally adequate but has clear gaps. It states what the tool does but doesn't explain the implications of enabling/disabling profiling, what data might be collected, or how to interpret results. For a tool that likely affects debugging/monitoring, 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 clear documentation for both parameters ('enabled' and 'port'). The description doesn't add any meaningful parameter information beyond what's already in the schema, so it meets the baseline score of 3 where the schema does the heavy lifting.

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 action ('Enable or disable profiling') and the resource ('platform channels'), providing a specific verb+resource combination. However, it doesn't differentiate this tool from sibling tools like 'dart_io_socket_profiling_enabled' or 'dart_io_http_enable_timeline_logging' that also appear to control profiling aspects, which prevents a perfect score.

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, nor does it mention any prerequisites or context for usage. While it's clear what the tool does, there's no information about appropriate scenarios or exclusions, leaving the agent to guess based on the tool name alone.

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