Notch TouchEngine bridge

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

The description adds a valuable caveat beyond the annotations: 'This does not validate a Notch license or target runtime; live validation remains explicit.' This discloses a key behavioral limitation. The annotations already indicate a mutating operation (readOnlyHint=false) and non-destructive intent, and the description does not contradict them.

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 two sentences, front-loaded with the primary purpose and followed by a precise caveat. Every sentence adds value, and there is no redundant or filler content.

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 10-parameter schema with full descriptions and annotations covering mutation/non-destructiveness, the description is sufficient. It clarifies the scope ('guarded scaffold') and the validation limitation, but does not detail the 'guarded' mechanism or output behavior. Overall, this is adequate for the tool's complexity.

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 the baseline is 3. The description does not add extra meaning to parameters beyond summarizing the scaffold features (notes, output, controls), which is already reflected in the schema properties. No additional parameter-level guidance is provided.

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 action ('Build a guarded Notch TOP or Engine COMP/TouchEngine bridge scaffold') with specific components (notes, output, optional play/speed controls). It distinguishes itself from potential siblings by specifying that it creates a scaffold and explicitly disclaims license/runtime validation.

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 implies usage by describing what it builds, but it does not explicitly state when to use this tool over alternatives like 'connect_touchengine_notch' or 'create_engine_comp'. No exclusionary guidance is provided, leaving the agent to infer from the scaffold-focused language.

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