Claude WebSearch Skill
Use the bundled script to search the web via Claude Code CLI (primary) or Codex CLI (fallback). Both CLIs expose a native WebSearch tool — no third-party search API key needed.
When to Use
- Tavily / Brave / Exa quota is exhausted
- User says "websearch搜一下X", "search for X", "查一下X"
- Any web search need where no API key is configured
Quick Usage
# Primary (Claude Code CLI — fast, recommended)
scripts/websearch.sh "your query"
# With result count
scripts/websearch.sh "your query" --max 3
# Explicit backend
scripts/websearch.sh "your query" --backend codex
Or use the global alias (if installed):
ccws "your query"
How It Works
| Backend | CLI flag | Notes |
|---|---|---|
claude (default) |
--allowedTools "WebSearch" |
Fast (~5s), clean output |
codex |
--search + reasoning_effort=low |
Slower (~30-60s), use as fallback |
The script auto-detects which CLI is available; claude is preferred when both exist.
Setup (one-time)
Install the global alias ccws for quick access:
ln -sf "$(pwd)/scripts/websearch.sh" ~/.local/bin/ccws
Troubleshooting
| Problem | Fix |
|---|---|
claude: command not found |
Install Claude Code CLI: npm install -g @anthropic-ai/claude-code |
codex: command not found |
Install Codex CLI: npm install -g @openai/codex |
| Claude returns empty output | Check claude auth status; re-login if expired |
| Codex times out | Normal — use --backend claude instead |
Not inside a trusted directory (Codex) |
Script handles this by running from a temp dir |
