Fl Write Midi File

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

The description discloses the mapping behavior (each track becomes a channel with GM sound, markers included) and that times are in beats. However, it does not mention side effects like file overwriting, permissions, or whether the operation is non-destructive.

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 concise, front-loaded with the main purpose, and uses a clear format to explain nested parameters. It avoids unnecessary verbosity while covering all 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 complexity of the parameter structure, the description covers purpose, parameter semantics, and key behavior. It does not mention return values, but an output schema exists, so this is acceptable. Minor gaps like file path handling are not critical.

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 description adds substantial meaning to the parameters by defining the structure of 'tracks' and 'markers', including field names, value ranges (channel 0-15, program 0-127), and units (time in beats). This goes far beyond the schema, which has no descriptions.

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 writes a multi-track MIDI file and explains the behavior when dragged into FL. The verb 'write' and resource 'MIDI file' are specific, and it is distinct from sibling tools that manipulate FL state directly.

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 does not explicitly state when to use this tool over alternatives. It lacks information about conditions or prerequisites, such as when writing an external MIDI file is preferable to using FL's native channel/note editing tools.

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