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

With readOnlyHint=false potentially confusing an agent, the description resolves the ambiguity by stating these are read-like POST requests that do not publish to social platforms. It also discloses two behaviors annotations do not cover at all: that the call may consume paid API credits and that confirm=true is mandatory.

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?

Front-loaded with the purpose, then return shape, then pagination, then the credit/confirm caveat — a sensible ordering. The enumeration of seven returned fields is somewhat chatty, but each element is informative given there is no output schema.

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?

With no output schema, the description carries the full burden of the return contract and does so (followings array fields plus total count), alongside pagination guidance and the credit/confirm side-effect notice. Nothing material for a correct invocation is missing.

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?

Schema description coverage is 100%, so all five parameters are already documented, including min_time's pagination role and account's credential semantics. The description reinforces min_time pagination but adds no syntax or format detail beyond the schema, so the baseline 3 applies.

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?

Names a specific verb+resource (retrieves the following list) and defines the direction explicitly as 'accounts that a TikTok user follows', which cleanly separates it from the sibling tiktok_followers. The lookup key (handle) and the exact shape of the result are stated up front.

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?

Gives clear operational context: paginate using min_time from the previous response, and confirm=true is required for the credit-consuming call. It does not explicitly name a competing sibling (e.g. tiktok_followers, tiktok_profile) or state when-not to use it, so it falls short of full alternative routing.

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