Fl Music Drums

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

The description discloses that the tool 'writes' patterns into the step sequencer, implying a project modification. However, it does not state whether it overwrites existing patterns, whether it creates a new pattern, or how it interacts with the current project state. No annotations are present to fill this gap.

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 compact and avoids filler, packing pattern options, JSON syntax, channel mapping, and no-argument behavior into two sentences. It is slightly dense but still readable and well organized.

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?

The description covers the main action and two parameters, but omits the meaning of 'bars' and 'fl_pattern', the return value when listing patterns, and the relationship to the current pattern/channel selection. Given the tool's complexity and lack of schema descriptions, it is only partially complete.

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 explains the 'pattern' parameter with built-in names and custom JSON, and describes the 'channel_map' object format. However, it does not explain the 'bars' or 'fl_pattern' parameters at all, leaving 50% of the schema undocumented. Since the schema itself has no descriptions, this is a notable gap.

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 drum patterns into the step sequencer and lists patterns when no arguments are provided. It names concrete built-in patterns and custom JSON support, so the core purpose is unambiguous.

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?

It gives a conditional usage instruction ('No arguments = list patterns') and explains the input format, but it does not explicitly say when to prefer this tool over sibling music tools like fl_music_theory or fl_music_progression. Some context is implied but no alternatives are mentioned.

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