Recording to composition (ISWC)

get_work_codes

Retrieve ISWC work codes for recordings using ISRC or SonoVault track ID. Essential for royalty and publishing workflows, especially for recordings with multiple works.

Instructions

Find the ISWC work code(s) behind a recording, by ISRC or SonoVault track ID. Useful for royalty and publishing workflows. One recording can carry several ISWCs (medleys, samples).

TDQS

A3.9/5.0
Behavior3/5

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

With no annotations, the description must cover behavioral traits. It mentions that one recording can have multiple ISWCs, a key nuance. However, it does not specify the return format, pagination, or error behavior, leaving gaps in transparency.

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 three concise sentences, front-loaded with the core action. Every sentence adds value without repetition or fluff.

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?

Without an output schema, the description should more fully explain the return structure. While it indicates multiple ISWCs may be returned, it omits details on format or empty results, leaving the agent with incomplete expectations.

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?

Schema coverage is 100% with clear parameter descriptions. The description restates the parameters without adding new meaning, so it does not exceed the baseline expectation for parameter semantics.

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 tool finds ISWC work codes based on a recording, using ISRC or track ID. It distinguishes from sibling tools by focusing specifically on ISWC mapping for royalty workflows.

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

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description indicates use for royalty and publishing workflows, providing clear context. However, it does not explicitly contrast with sibling tools like get_recordings_of_work or lookup_isrc, leaving some ambiguity about when to choose this tool over alternatives.

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