List follower ids of a Twitter profile

twitter_profile_followers_ids_list

Read-only

List numeric user ids of accounts following an X profile. Accepts a handle or numeric user id. Returns a list (use cursor when paginated).

Input Schema

TableJSON Schema

Name	Required	Description
`by`	No	Treat the path value as a handle or a numeric user id. Defaults to id when the value is all digits.
`trim`	No	Ignored if this tool does not support it.
`urls`	No	Alias for `handle`. Prefer `handle`.
`user`	No	Alias for `handle`. Prefer `handle`.
`limit`	No	Requested page size (1–5000).
`cursor`	No	Opaque pagination cursor returned by a previous response.
`handle`	No	X (Twitter) profile handle without the leading @, or a numeric user id.
`offset`	No	Ignored if this tool does not support it.
`context`	Yes	Describe the user's underlying goal in one sentence — not the tool you are calling.
`pageSize`	No	Ignored if this tool does not support it.
`userName`	No	Alias for `handle`. Prefer `handle`.
`username`	No	Alias for `handle`. Prefer `handle`.
`llm_model`	Yes	The exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.
`maxResults`	No	Ignored if this tool does not support it.
`profileUrl`	No	Alias for `handle`. Prefer `handle`.
`linkedinUrl`	No	Alias for `handle`. Prefer `handle`.
`max_results`	No	Ignored if this tool does not support it.
`screen_name`	No	Alias for `handle`. Prefer `handle`.
`conversation_id`	No	Echo the conversation_id from the server's previous response. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it.

TDQS

A3.8/5.0

Behavior3/5

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

Annotations already establish readOnlyHint=true and openWorldHint=true, so the description does not need to cover safety. It adds pagination and return-type behavior ('Returns a list (use cursor when paginated)'), which is useful, but it does not disclose details such as rate limits, empty-result behavior, or response envelope structure. No contradiction with annotations.

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 compact sentences with no filler. The core action and return type are front-loaded, and the pagination hint earns its place as immediately actionable operational guidance.

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 read-only listing tool with rich schema documentation, the description covers the essential invocation and pagination behavior. However, there is no output schema, and the description only vaguely says 'Returns a list' without spelling out the exact response shape or how the cursor is returned, and it does not differentiate from the sibling followers_list tool.

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%, and the schema already explains handle, by, limit, cursor, and required context/llm_model parameters. The description's mention of accepting a handle or numeric user id largely repeats the schema's `handle` description, so it adds minimal value beyond the structured schema.

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 and resource: 'List numeric user ids of accounts following an X profile.' It clearly differentiates this tool from siblings like twitter_profile_followers_list and twitter_profile_followers_verified_list by emphasizing that the return value is numeric user IDs, not full profile objects.

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

Usage Guidelines3/5

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

The description gives useful operational guidance—'Accepts a handle or numeric user id' and 'use cursor when paginated'—but does not explicitly state when to prefer this tool over the closely related twitter_profile_followers_list or twitter_profile_following_ids_list. The usage context is implied rather than explicitly contrasted with alternatives.

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