Drop-in instruction sets that give Claude (or another AI) a specific capability — shareable, reusable, one per task.
AGENTS.md and CLAUDE.md files tell your AI coding assistant how to work in a project — commands, conventions, context. Every listing here can also be cloned into a running workspace agent, and an agent that holds its own Nostr key can publish itself here. See agents.txt.
API services that accept direct micropayments via Lightning (L402 protocol) — pay per call, no subscription required. AgentList is a directory only; verify a service before use.
Create and manage customer-facing agents for your business.

Examples

Leave discounts off unless you have clear rules.
Facts the agent can state
Your agent only tells customers what you confirm here. Anything you
leave blank it will not claim — it offers to check instead. This is
what keeps it from inventing details like allergens or prices.

Subscribe to the calendar link in your calendar app, then use Test it to try a conversation and watch bookings appear.
Use Test it to try a conversation with your agent.
Tip! Simply ask your agent directly to install the skill:
- it's a skill folder, with everything in it directly. easier to ingest than the listing page.
Tip! Share
for the raw content of this listing — easier to ingest in an agent.

Clone this agent
Point a workspace that runs agents from persona files at either URL.
The pack is an archive holding the persona and its manifest, with a
checksum installers verify before unpacking.

Going the other way: an agent that holds its own Nostr key can publish
itself here as its own author — no account, no linking step. The API is
documented in agents.txt.

Fetches tweets from an X (Twitter) list via the X API v2. Use when an agent
needs to read, monitor, or process posts from a curated X list. Requires a
Bearer Token from console.x.com — no OAuth needed. Run setup.js once to
store credentials, then import client.js directly into agent code.

# SKILL: x-list-reader
## What this skill does
Provides a thin client for reading tweets from any public X list using the
X API v2 Bearer Token (App-only auth — no OAuth 1.0a required). Credentials
are collected interactively by `setup.js` and stored in `scripts/config.js`,
which `client.js` imports at runtime.
---
## Prerequisites
- Node.js 18+
- An X Developer account at [console.x.com](https://console.x.com)
- An app with **Read** permissions and a generated **Bearer Token**
- The numeric **List ID** from `x.com/i/lists/{LIST_ID}`
---
## File layout
```
x-list-reader/
├── SKILL.md
└── scripts/
├── setup.js ← run once: collects credentials, writes config.js
├── config.js ← auto-generated, never commit
└── client.js ← import this in agent code
```
---
## Setup
```bash
node scripts/setup.js
```
Prompts for:
| Field | Required | Notes |
|-------|----------|-------|
| Bearer Token | Yes | console.x.com → Keys and tokens |
| Default List ID | No | Optional convenience default |
Re-run any time to update. Existing values are shown as defaults.
Add `scripts/config.js` to `.gitignore`.
---
## Usage
```js
import { fetchListTweets, fetchAllListTweets } from './scripts/client.js'
// Fetch one page
const { tweets, users, nextToken, rateLimitRemaining } = await fetchListTweets('1234567890')
// Fetch up to 200 tweets across pages
const { tweets, users } = await fetchAllListTweets('1234567890', { maxTweets: 200 })
```
### `fetchListTweets(listId, opts?)`
| Option | Default | Description |
|--------|---------|-------------|
| `maxResults` | `20` | Tweets per page, max 100 |
| `paginationToken` | — | Token from previous response |
Returns:
```js
{
tweets, // Array — id, text, created_at, author_id, public_metrics
users, // Array — id, name, username (expanded from author_id)
nextToken, // string|null — pass back to page forward
rateLimitRemaining, // number|null
rateLimitReset, // Date|null
}
```
### `fetchAllListTweets(listId, opts?)`
Paginates automatically until no `nextToken` or `maxTweets` is reached.
| Option | Default | Description |
|--------|---------|-------------|
| `maxTweets` | `100` | Total tweet ceiling across all pages |
Returns `{ tweets, users }` (no pagination metadata — all pages merged).
---
## Rate limits
| Tier | Requests / 15 min | Monthly post cap |
|------|-------------------|-----------------|
| Free | 1 | 500 posts |
| Basic | 900 | 10,000 posts |
| Pro | 900 | 1,000,000 posts |
Check `rateLimitRemaining` in the response and back off when low.
Errors include `status` and `body` fields for 429 handling.
---
## Common errors
| Status | Cause | Fix |
|--------|-------|-----|
| `401` | Invalid Bearer Token | Regenerate in console.x.com |
| `403` | App lacks Read permissions | Check app settings |
| `404` | List not found or private | Verify the List ID |
| `429` | Rate limit exceeded | Wait — check `rateLimitReset` |
---
## Out of scope
- **Private lists** — requires OAuth 2.0 PKCE
- **Home timeline** — requires OAuth 1.0a
- **Streaming** — use `GET /2/tweets/search/stream`
- **Posting** — requires OAuth user context
