twitter_followers_you_know

Read-only

Find which followers of a target user ID you also follow, revealing mutual connections. Returns profile data per overlap plus cursor.

Instructions

List the 'Followers you know' for a target user id: the followers of that account that YOUR authenticated account also follows (mutual-connection overlap). Requires an authenticated session behind your key. Returns profile data per overlap account plus a cursor.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
ct0NoOptional. The account's ct0 cookie, paired with auth_token. Sent as the x-ct0 header.
countNoRequested page size, capped at 200. Advisory only for this endpoint: X's own search backend typically returns around 13 to 20 tweets per page regardless of the value requested here, an upstream limit, not something this API controls. To retrieve more results, page with the cursor from the previous response rather than raising this value.
cursorNoOpaque pagination cursor from a previous response's next_cursor field. Omit on the first call; pass on subsequent calls to fetch the next page.
user_idYesNumeric user id of the target account to compute shared followers against.
proxy_urlNoOptional. Residential proxy URL to egress this call through. Recommended for writes: X soft-blocks writes from datacenter IPs as automated. Sent as the x-proxy-url header.
auth_tokenNoOptional. The account's auth_token cookie, to act AS that account for this call (must be paired with ct0). Sent as the x-auth-token header; never placed in the URL.
user_agentNoOptional. User-Agent string to send for this session. Sent as the x-user-agent header.

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral context the annotations do not: it requires an authenticated session behind the key and discloses the return shape (profile data per overlap account plus a cursor).

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?

Two tight sentences: the first front-loads the operation and its precise semantics, the second covers the auth prerequisite and return values. No filler or repetition of the name.

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?

Covers purpose, auth prerequisite, and return payload, which is sufficient given a 100%-covered schema and no output schema. A mention of practical pagination behavior would complete it, but nothing essential for correct invocation is missing.

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%, so the schema already fully documents user_id, cursor, count, and the auth/cookie parameters. The description only restates the target user_id and cursor conceptually without adding syntax or format detail, so baseline 3 is appropriate.

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?

States a specific verb+resource ('List the Followers you know for a target user id') and immediately defines the exact semantic scope: mutual-connection overlap between the target's followers and the caller's own follows. This distinguishes it from the many sibling follower tools such as twitter_user_followers and twitter_user_following.

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?

Gives clear context: requires an authenticated session behind your key, and the target user id is the input. It does not name an explicit alternative (e.g. twitter_check_follow_relationship) or state when-not to use it, so it stops short of full routing guidance.

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