Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00060 | $0.00774 |
| Opus 5 | $0.00030 | $0.00387 |
| Sonnet 5 | $0.00012 | $0.00155 |
| Haiku 4.5 | $0.00006 | $0.00077 |
Grade A, and why
lists-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

List Manager
File: src/listManager.js
Browser console script that creates lists, adds members by username, and exports member data.
How to Use
- Navigate to
x.com/YOUR_USERNAME/lists(or an existing list page) - Open DevTools (F12) → Console
- Edit the CONFIG section to enable desired operations
- Paste the script → Enter
Configuration
const CONFIG = {
createList: {
enabled: false,
name: 'My List',
description: 'Created by XActions',
isPrivate: true,
},
addUsers: {
enabled: true,
usernames: ['user1', 'user2'],
},
exportMembers: {
enabled: false,
maxMembers: 200,
},
actionDelay: 2000,
};
Create List
Sets createList.enabled: true to create a new list. Fills in the name, description, and privacy toggle, then saves.
Add Members
Sets addUsers.enabled: true with a list of usernames. Opens the add-member search, types each username, clicks the matching user cell, and repeats. Navigate to the target list page first.
Export Members
Sets exportMembers.enabled: true. Scrolls through the list members page and exports all members (username, display name, bio) as a JSON download.
DOM Selectors
| Element | Selector |
|---|---|
| Create list button | [data-testid="createList"] |
| List name input | [data-testid="listNameInput"] |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lists-management is a skill published in the GitHub repository nirholas/XActions (502 stars, last pushed today), licensed Apache-2.0. It adds 60 tokens to every session and 774 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
