Soundiiz

Check Soundiiz transfer compatibility

getSoundiizTransferCompatibility
Read-onlyIdempotent

Check transfer and one-way playlist-sync capabilities between two exact public platform slugs, such as spotify and youtube-music. Return supported item types and human-readable web guide URLs from the cached Soundiiz capability catalog. Show the exact returned guideUrl links, including query parameters, to users. This does not check account eligibility or live status. Import corenames can differ from public slugs.

Input Schema

NameRequiredDescriptionDefault
sourceYesExact source slug from https://soundiiz.com/capabilities.json; not a URL.
destinationYesExact destination public slug, for example youtube-music rather than import corename ytmusic.

  2. First observed

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, and the description adds real value on top: results come from a cached catalog rather than live status, account eligibility is out of scope, and guideUrl values must be surfaced verbatim including query parameters. It does not discuss staleness of the cache or failure behavior for unknown slugs.

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?

Front-loaded with the core action and scope, then constraints and the guideUrl display rule. Dense but each sentence carries distinct information; the final corename note is slightly abrupt but relevant.

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

Completeness5/5

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

An output schema exists so return values need not be re-explained, and the description still covers the important output-handling rule (show exact guideUrl links with query parameters) plus scope limits. Nothing an agent needs to invoke and use the result correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds meaning beyond the schema by stressing 'exact public platform slugs' and warning that import corenames can differ from public slugs (e.g. ytmusic vs youtube-music), which is the main misuse risk for these parameters.

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?

States a specific verb and resource ('Check transfer and one-way playlist-sync capabilities between two exact public platform slugs') and scopes it to the cached Soundiiz capability catalog, which clearly separates it from createSoundiizImportLink and listSoundiizImportDestinations.

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?

Gives clear context for when to call it (checking transfer/one-way sync support between two platforms) and an explicit exclusion ('does not check account eligibility or live status'). It does not name the sibling tools as alternatives, so it stops short of a 5.

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