follow_artists_or_users

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states the action 'Follow' without explaining side effects, authentication requirements, idempotency, or what happens when an ID is already followed. It does not mention that this is a mutating operation requiring an access token, which is critical context for an agent. The verb itself signals mutation, but little else is disclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the core purpose, followed by a compact Args section. Every sentence contributes value and there is no filler, making it easy for an agent to parse quickly.

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

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

The tool has no output schema and no annotations, so the description needs to be self-sufficient. It covers the main parameters but omits authentication expectations, return/response behavior, and any error or edge-case context. For a state-changing follow operation, this leaves important gaps that an agent would have to guess or infer.

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

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

The description adds concrete meaning for two of the three parameters: 'ids' is explained as a comma-separated list, and follow_type is constrained to 'artist' or 'user'. However, access_token is left undocumented, and the schema has no descriptions, so the token parameter's role and optionality remain unclear. This is partial compensation for a 0% schema description coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Follow artists or users.' It clearly distinguishes this from sibling tools like unfollow_artists_or_users and follow_playlist by naming exactly which entity types are affected. The Args block reinforces the scope by showing the follow_type values.

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

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

The description implies when to use the tool: whenever the goal is to follow artists or users. However, it provides no explicit guidance about alternatives, such as using get_followed_artists to list followed artists or unfollow_artists_or_users to reverse the operation. This leaves routing to inference rather than clear instruction.

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