Fl Notes Add

fl_notes_add

Queue MIDI notes into the active FL Studio piano roll, specifying pitch, time, duration, velocity, and more. Applies when FL Studio is the foreground window.

Instructions

Queue notes for the open piano roll: [{midi, time, duration, velocity?, pan?, color?, slide?, porta?, fcut?, fres?, pitchofs?}] (beats; velocity 0-1). Applied by the FL Bridge Notes script; auto_trigger presses its hotkey only when FL Studio is already the active window.

B3.2/5.0
Behavior3/5

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

With no annotations, the description carries the full burden of disclosing behavior. It does explain that notes are queued, applied by the FL Notes Bridge script, and that auto_trigger only presses the hotkey when FL Studio is active. However, it omits the effect of the replace parameter and any side effects of queuing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense but not bloated; it packs important note fields, units, and behavioral caveats into two sentences. It is front-loaded with the primary action and resource. Minor redundancy in the note field list is acceptable given the schema provides no descriptions.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description provides the essential purpose and note structure, but it lacks guidance on the replace parameter and does not mention the return value or output schema. Given the moderate complexity and missing schema descriptions, it is adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description compensates for the missing schema descriptions by detailing the notes array fields, units, and velocity range. It also partially explains auto_trigger. But the replace parameter is not mentioned at all, leaving one of three parameters undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool queues notes for the open piano roll, identifying the resource and action. It also lists the note fields, which helps distinguish it from editing or state-related sibling tools. However, it does not explicitly contrast with fl_notes_edit or mention the replace behavior.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 versus alternatives like fl_notes_edit or fl_notes_state. It mentions the auto_trigger hotkey behavior but gives no guidance on when queuing is appropriate or how it relates to other note operations.

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