setlist_get_setlist_version

Read-only

Retrieve a specific historical version of a setlist by its version ID. Use this to view past edits and song details for any setlist revision.

Instructions

Get a specific historical version of a setlist by its version ID. Setlists are wiki-edited; each edit has a version ID returned in a setlist's versionId field. A setlist's songs live in sets.set[]; each set may have an encore number (1 = first encore) and a name (e.g. an acoustic set or a full album). Each song may carry: tape: true (pre-recorded intro/outro/interlude — not actually performed), cover (the original artist when it is a cover), with (a guest performer), and info (a note like "acoustic" or "first time live"). Results include a setlist.fm url; when you present this data, cite it as a clickable source link to setlist.fm (their API terms require followable attribution — no nofollow). If a result has no url, link to https://www.setlist.fm instead.

Input Schema

No field projection: this server has no verified record of which Setlist.fm fields matter, and inventing one would risk dropping a field a caller needs.

A4.6/5.0
Behavior5/5

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

Beyond the readOnlyHint annotation, the description discloses important attribution requirements: results include a setlist.fm url, and the agent must present it as a clickable source link with no nofollow. It also reveals a fallback behavior when url is missing (link to https://www.setlist.fm), which is the kind of non-obvious behavior an agent needs. It also explains field semantics like tape, cover, with, info, and encore.

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 substantial but every sentence adds necessary context: the wiki-edit concept, the data structure, and the attribution requirement. It could be slightly tighter, but it is logically organized and front-loads the tool's purpose.

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?

Given there is no output schema, the description carries the burden of explaining what the response looks like (sets, set[], songs, encore, name, tape, cover, with, info, url). For a GET tool with readOnlyHint and no destructive behavior, this is complete for an agent to call and interpret the result correctly.

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 description coverage is 100%, so the schema already documents both parameters. The description adds meaning to versionId by explaining where it comes from ('returned in a setlist's versionId field') and explains the response shape for view ('compact drops fields the response already carries elsewhere; full returns Setlist.fm's payload untouched'). This goes beyond the schema.

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 states a specific verb ('Get') and resource ('a specific historical version of a setlist by its version ID'), which is distinct from siblings like setlist_get_setlist. It also explains the wiki-edit context that frames what a version is.

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?

It clearly differentiates this tool from setlist_get_setlist by explaining that versionId comes from a setlist's versionId field, and it describes the data model enough to know when this version-specific lookup is needed. It does not explicitly name sibling alternatives or state 'use X instead', but the context is clear.

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