Charts and collections

discover_music

Read-only

Browse live music charts, genre and mood walls, and artist spotlights, plus chart snapshots back to 1946 to find what's trending or number one in a year.

Instructions

Browse live charts, genre and mood walls, editorial playlists, artist spotlights, and chart snapshots back to 1946 — "what's trending", "number one in 1994". Charts move weekly: call rather than recall. No arguments gives the chambers and featured walls; year gives that year's snapshots; wall gives its entries, each with a query for resolve_music. Add resolve: true with wall to get number one's links in the same call. RootVine never fabricates. Every link existed at resolved_at. Limits: UK-focused stores, prices in GBP; music only today — games are not live yet. On partial, say which sources didn't answer; on no_results, tell the user plainly — never fall back to guessing a link.

Input Schema

TableJSON Schema

Name	Required	Description
`wall`	No	A wall or chart-snapshot slug from an earlier answer (a BeatsVine wall address also works). Lists its entries; on a ranked chart position 1 is number one. Takes priority over `chamber` and `year`.
`year`	No	Chart snapshots from this year (1946 to now), for questions about the past — 'number one in 1994'. Pass a snapshot's slug back as `wall` for its entries. Takes priority over `chamber`.
`limit`	No	Max walls, entries or snapshots to return: 10 by default, 30 at most.
`chamber`	No	Chamber to browse; omit for an overview of all chambers and featured walls. 'by-genre' = genre corridors. 'for-this-moment' = moods and activities. 'charts' = live streaming charts. 'by-era' = decades. 'spotlights' = artist features.
`resolve`	No	With `wall`: also fetch number one's stream and buy links, in the same call.

TDQS

A4.6/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, but the description adds genuinely useful behavior: charts move weekly so call rather than recall, every link existed at resolved_at, no fabrication, UK/GBP scoping, and music-only (games not live). It stops short of describing pagination or the shape of results, but the output schema likely covers returns.

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?

Dense but front-loaded: what it browses, then the call-shape recipes, then trust/limits caveats. Every clause carries signal, though the trust paragraph (RootVine never fabricates, resolved_at) runs long relative to the rest.

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 explained; the description instead covers the gaps that matter — invocation modes, error handling on partial/no_results, geographic/currency limits, and what is not yet live. Nothing needed to call it 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 combination semantics the schema does not: passing a snapshot slug back as `wall`, and pairing `resolve: true` with `wall` to get number-one links in one call. Priority ordering is repeated from the schema, so this is a modest lift above baseline rather than a full 5.

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 (browse) plus concrete resources: live charts, genre/mood walls, editorial playlists, artist spotlights, and historical snapshots back to 1946. It also names resolve_music as the follow-on for the `query` values returned, which cleanly separates it from that sibling.

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

Usage Guidelines5/5

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

Gives explicit invocation recipes: no arguments yields chambers and featured walls, `year` yields that year's snapshots, `wall` yields entries, and `resolve: true` with `wall` fetches number-one links inline. It also states when not to guess and how to handle partial/no_results outcomes.

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