Verify MusicBrainz connectivity

musicbrainz_healthcheck
Read-onlyIdempotent

Confirm MusicBrainz API connectivity and OAuth write configuration, returning status and a plain-English hint.

Instructions

Confirm the MusicBrainz API is reachable (and our User-Agent accepted) by looking up a stable entity, and report whether the OAuth write path is configured. Reports {ok, reachable, oauth_configured} with a plain-English hint. Read-only.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, and openWorld hints. The description adds behavioral detail beyond this: it performs a lookup on a stable entity, verifies User-Agent acceptance, and reports on the OAuth write path. It also explicitly includes 'Read-only', reinforcing the annotations without contradicting them.

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 two sentences with no wasted words. The primary purpose is front-loaded, and the return shape and read-only nature are stated efficiently. Every clause adds meaningful information.

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?

For a zero-parameter, no-output-schema health check, the description is complete. It explains what the tool verifies, what it returns, and its safety profile. An agent can invoke it without any inputs and interpret the result correctly from the described fields and hint.

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?

The tool has zero parameters, and the input schema is empty, so there is no parameter semantics burden. The description usefully explains what the tool reports (ok, reachable, oauth_configured) and that a plain-English hint is included, which is sufficient for a no-argument health check.

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's function: confirm MusicBrainz API reachability and User-Agent acceptance, and report whether the OAuth write path is configured. This is a specific verb+resource combination that distinguishes it from sibling tools that perform lookups, searches, or submissions.

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 gives clear context for when to use it: to verify connectivity and OAuth configuration before or alongside other MusicBrainz operations. It does not explicitly name alternatives or exclusions, but the health-check purpose is self-evident and distinct from all listed siblings, so no further disambiguation is needed.

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