remove_automation_point

Deletes an automation breakpoint at a given beat position on a track's envelope. Specify track, slot, envelope, and time to remove the point.

Instructions

Remove a single automation breakpoint at a specific beat position.

TDQS

C2.7/5.0
Behavior2/5

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

With no annotations, the description carries the full burden. It states it removes a single breakpoint at a beat position but does not disclose side effects (e.g., what happens if the point doesn't exist, undo behavior, impact on playback). Minimal behavioral context is provided.

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 a single concise sentence that is front-loaded with the core action. However, it is so brief that it sacrifices necessary detail for conciseness, missing parameter context and behavioral notes.

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

Completeness1/5

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

Given the tool has 5 parameters with no schema descriptions, no annotations, and no output schema, the description is severely incomplete. It fails to explain how parameters relate to the operation, what values to use, or what the result looks like. The agent cannot reliably use this tool based solely on the description.

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

Parameters1/5

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

Schema description coverage is 0%, meaning param names and types are the only clues. The description adds no meaning for any of the five parameters (track_index, slot_index, envelope_index, time, duration), leaving an agent to guess their roles. This is wholly inadequate.

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

Purpose5/5

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

The description explicitly states the action 'Remove', the resource 'automation breakpoint', and the scope 'single', with a location 'at a specific beat position'. This clearly distinguishes it from siblings like 'clear_automation_envelope' (removes all points) and 'add_automation_points' (adds points).

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?

No guidance is provided on when to use this tool versus alternatives such as 'clear_automation_envelope' or 'delete_automation_envelope'. The description only states what it does, not when or when not to use it.

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