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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It states 'Toggle disabling' which implies a mutation (changing app state), but doesn't disclose effects (e.g., visual changes, performance impact), reversibility, permissions needed, or side effects. The RPC mention hints at network communication but lacks details like error handling or response format.

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 front-loads key information ('RPC: Toggle disabling of clip layers in the Flutter app'). Every word contributes meaning without redundancy, making it appropriately concise.

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 (mutating app state via RPC), lack of annotations, and no output schema, the description is insufficient. It doesn't explain what 'clip layers' are, the impact of toggling them, error conditions, or return values. For a debugging tool that alters runtime behavior, more context is needed.

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 100%, so parameters 'enabled' and 'port' are fully documented in the schema. The description adds no additional parameter semantics beyond implying the toggle action relates to 'clip layers'. This meets the baseline for high schema coverage.

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 ('Toggle disabling') and target resource ('clip layers in the Flutter app'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'debug_disable_opacity_layers' or 'debug_disable_physical_shape_layers', which appear to be similar debugging tools for different layer types.

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?

No guidance is provided on when to use this tool versus alternatives. The description mentions it's an 'RPC' but doesn't specify prerequisites (e.g., needing a running Flutter app), appropriate contexts, or exclusions. This leaves the agent without usage direction.

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