ui_hint

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

The description lacks details beyond the basic action. It does not explain the 'transient' nature (e.g., duration), whether the message overwrites previous hints, or any side effects. Since no annotations are provided, the description carries the full burden but fails to sufficiently disclose behavior.

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 brief and front-loaded, but it is too terse, sacrificing helpful context. While concise, it could include more information without becoming verbose.

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 simplicity with one parameter and no output schema, the description is incomplete. It omits usage context, parameter details, and behavioral nuances that an AI agent would benefit from for correct invocation.

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 0% description coverage for its single parameter 'message'. The description does not add any additional meaning, constraints, or formatting hints for the parameter, leaving the agent unclear about what kind of string is expected.

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 ('Display') and the resource ('a transient hint message in FL Studio's status bar'). It is specific and distinguishes this tool from sibling tools like ui_hide_window or ui_show_window, which have different purposes.

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 instead of others. The description does not mention alternative tools, prerequisites, or scenarios where this tool is appropriate or inappropriate.

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