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

With no annotations, the description carries the burden and does so well: it discloses that the list is potentially limited and not guaranteed complete, and that restricted lists fail with an upstream error. It omits auth/permission requirements and rate-limit behavior, which keeps it from a 5.

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?

Three dense sentences, front-loaded with the core action and then the return shape, followed by the limitation and pagination rule. Every sentence carries distinct information and there is no filler.

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?

For a paginated read tool with no annotations and no output schema, the description covers return fields, pagination discipline, dataset limitations, and error behavior. The main remaining gap is authentication or access prerequisites for private/restricted creators.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning by tying max_cursor/min_cursor to the returned cursor values and constraining their use to when hasMore is true. That operational guidance goes beyond the schema's per-field strings.

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?

States a specific verb ('Get one native page') and resource ('TikTok's available follower list') with explicit scope ('for the specified creator'). It also distinguishes itself from the sibling audience_demographics by stating it is 'not audience demographics', so an agent can tell the tools apart without opening schemas.

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 concrete usage rules: advance cursors only while hasMore is true, and expect an upstream error for restricted lists. It implicitly routes away from audience_demographics for demographic data, but does not explicitly state when to prefer creator_following or other list tools, so it stops short of the full when/when-not/alternatives bar.

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