setlist_get_user

Read-only

Retrieve a setlist.fm user's public profile by username to identify concert activity and provide a clickable source link for attribution.

Instructions

Get a setlist.fm user's public profile by their userId (their setlist.fm username). 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

TableJSON Schema
NameRequiredDescriptionDefault
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns Setlist.fm's payload untouched. 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.

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, and the description does not contradict that. It adds useful behavioral context beyond the annotation by explaining the setlist.fm attribution requirement: present the returned url as a clickable source link, use followable attribution with no nofollow, and fall back to https://www.setlist.fm when no url exists.

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 compact and front-loaded: the first sentence states the operation and key parameter, while the following sentences address attribution behavior. Every sentence carries necessary information, and there is no filler or repetition.

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?

For a simple read-only lookup with fully documented parameters and a readOnlyHint annotation, the description covers the essential operational details: what the tool returns (a profile with a url), how to attribute the result, and the fallback behavior when no url is present. It does not describe error cases or all return fields, but those are less critical given the tool's simplicity.

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 description coverage is 100%, so the schema already documents both userId and view. The description adds only marginal clarification by equating userId with the username, which the schema already states. No additional parameter semantics are provided, so the baseline of 3 is appropriate.

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'), a specific resource ('a setlist.fm user's public profile'), and the key identifier ('their setlist.fm username'). This clearly distinguishes it from sibling tools like setlist_get_user_attended and setlist_get_user_edited, which target different user-related data.

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 makes the usage context clear: call this tool when you need a user's public profile by username. It does not explicitly mention alternatives or exclusion criteria, but the resource is specific enough that an agent can infer when this tool applies versus the attended/edited list tools.

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