apply_style

Apply a .mss style file to a score and export the styled result.

Instructions

Apply a MuseScore style file (.mss) to a score and re-export.

Args: score_b64: Base64-encoded score file. input_suffix: Input extension, e.g. "mscz". style_b64: Base64-encoded .mss style file content.

Returns: Base64-encoded mscz with the style applied.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

B3.4/5.0

Behavior2/5

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

No annotations are provided, so the description carries the full burden. It states that the tool applies a style and re-exports a score, but it does not disclose any side effects, permission requirements, or failure modes. As a transformation, it implies no destruction, but the description could be richer.

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

Conciseness5/5

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

The description is brief, well-structured with clear sections for Args and Returns. Every sentence serves a purpose, and there is no redundant information.

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

Completeness4/5

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

The description covers the input parameters and return value adequately. Given the existence of an output schema, it does not need to elaborate on the return format. However, it lacks details on error handling or constraints on the style file, which would improve completeness.

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?

With 0% schema description coverage, the description compensates by explaining each parameter's purpose and format (e.g., Base64-encoded, input suffix example). However, it does not clarify the role of 'input_suffix' beyond an example, leaving some ambiguity.

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 clearly states the action (apply), the resource (MuseScore style file .mss to a score), and the outcome (re-export). It is specific and distinguishes this tool from its siblings, which include other operations like batch_convert, change_tempo, etc.

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 provide any guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or situations where it should not be used. It simply describes the operation without context.

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