felo-x-search

name	felo-x-search
description	Search X (Twitter) data using Felo X Search API. Use when users ask about X/Twitter users, tweets, trending topics on X, tweet replies, or when explicit commands like /felo-x-search are used. Supports user lookup, user search, user tweets, tweet search, and tweet replies.

Felo X Search Skill

When to Use

Trigger this skill when the user wants to:

• Look up X (Twitter) user profiles by username
• Search for X users by keyword
• Get tweets from a specific X user
• Search tweets by keyword or advanced query
• Get replies to specific tweets

Trigger keywords (examples):

• English: twitter, tweet, X user, X search, tweets from, replies to, trending on X
• 简体中文: 推特, 推文, X用户, X搜索, 推文回复
• 日本語: ツイッター, ツイート, Xユーザー, X検索

Explicit commands: /felo-x-search, "search X", "search twitter"

Do NOT use for:

• General web search (use felo-search)
• Webpage extraction (use felo-web-extract)
• Generating slides (use felo-slides)

Setup

1. Get API key

1. Visit felo.ai
2. Open Settings -> API Keys
3. Create and copy your API key

2. Configure environment variable

Linux/macOS:

export FELO_API_KEY="your-api-key-here"

Windows PowerShell:

$env:FELO_API_KEY="your-api-key-here"

How to Execute

Option A: Use the bundled script or packaged CLI

Packaged CLI (after npm install -g felo-ai):

felo x [query] [options]

Script (from repo):

node .agents/skills/felo-x-search/scripts/run_x_search.mjs [query] [options]

Usage Pattern

The x command uses parameter combinations to infer intent — no subcommands needed.

With query (search mode):

Usage	Behavior
felo x "AI news"	Search tweets (default)
felo x -q "AI news"	Same as above
felo x "OpenAI" --user	Search users

With --id (lookup mode):

Usage	Behavior
felo x --id "1234567890"	Get tweet replies (default)
felo x --id "elonmusk" --user	Get user info
felo x --id "elonmusk" --user --tweets	Get user tweets

Options

Option	Description
[query]	Positional arg, search keyword (equivalent to -q)
-q, --query <text>	Search keyword
--id <values>	Tweet IDs or usernames (comma-separated)
--user	Switch to user mode
--tweets	Get user tweets (with --id --user)
-l, --limit <n>	Number of results
--cursor <str>	Pagination cursor
--include-replies	Include replies (with --tweets)
--query-type <type>	Query type filter (tweet search)
--since-time <val>	Start time filter
--until-time <val>	End time filter
-j, --json	Output raw JSON
-t, --timeout <seconds>	Timeout in seconds (default: 30)

# Search tweets
curl -X POST "https://openapi.felo.ai/v2/x/tweet/search" \
  -H "Authorization: Bearer $FELO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "AI news", "limit": 20}'

# Search users
curl -X POST "https://openapi.felo.ai/v2/x/user/search" \
  -H "Authorization: Bearer $FELO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "artificial intelligence"}'

# Get user info
curl -X POST "https://openapi.felo.ai/v2/x/user/info" \
  -H "Authorization: Bearer $FELO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"usernames": ["elonmusk", "OpenAI"]}'

# Get user tweets
curl -X POST "https://openapi.felo.ai/v2/x/user/tweets" \
  -H "Authorization: Bearer $FELO_API_KEY" \
  -H "Content-Type: application/json" \

Link Validation

每次輸出推文連結前，必須執行以下檢核，確保連結正確：

1. 連結格式：推文連結必須為 https://x.com/{username}/status/{tweet_id}，username 與 tweet_id 均來自 API 回傳的資料，禁止自行推測或填入預設值。
2. 資料對應：連結中的 username 必須與該推文的 author.username 欄位一致，tweet_id 必須與 id 欄位一致。
3. 禁止捏造：若 API 未回傳 tweet_id 或 username，則該則推文不得附上連結，改為標注「連結不可用」。
4. 用戶連結：用戶頁面連結格式為 https://x.com/{username}，同樣只能使用 API 回傳的 username。

Error Handling

Common Error Codes

• INVALID_API_KEY — API Key is invalid or revoked
• X_SEARCH_FAILED — X search request failed (check parameters or downstream error)

Missing API Key

If FELO_API_KEY is not set, display setup instructions and stop.

API Reference (summary)

• Base URL: https://openapi.felo.ai. Override with FELO_API_BASE env if needed.
• Auth: Authorization: Bearer YOUR_API_KEY
• Endpoints:
  • POST /v2/x/user/info — Batch get user profiles
  • POST /v2/x/user/search — Search users
  • POST /v2/x/user/tweets — Get user tweets
  • POST /v2/x/tweet/search — Search tweets
  • POST /v2/x/tweet/replies — Get tweet replies

Important Notes

• ⚠️ 路徑安全：skill 腳本位於 repo root 的 .agents/skills/ 下。若 cwd 不在 repo root，先執行 git rev-parse --show-toplevel 取得路徑再 cd。禁止用 $(...) 語法。
• Always check FELO_API_KEY before calling; if missing, return setup instructions.
• Format output as readable Markdown by default; use --json for raw API response.
• Use pagination cursors (next_cursor) for fetching more results.
• For tweet search, advanced query syntax is supported (same as X advanced search).
