name	serper
description	Search the web or scrape webpages via Serper using the plugin runtime script at skills/serper/scripts/run-serper.js.

Serper Skill

This skill follows a plugin-first, script-first runtime model.

Canonical runtime entrypoint (Claude resolves paths relative to skill location):

node ./scripts/run-serper.js

Use this skill when you need:

• web search for current information
• webpage extraction from a URL
• structured JSON output for further processing

Process (scheduler-style, adapted for on-demand API calls)

1. Determine operation: search or scrape.
2. Validate required input:
   • search: --query
   • scrape: --url
3. Execute the runtime script using the relative path.
4. Return JSON output directly.
5. Surface clear API/network/rate-limit errors.

Commands

Search

node ./scripts/run-serper.js search \
  --query "{{query}}" \
  [--gl us] \
  [--hl en] \

• --timeout (optional): timeout in milliseconds, default 30000

Environment

Set one of:

SERPER_API_KEY=your_api_key_here
# or
SERPER_API_KEYS=key1;key2;key3

Env resolution precedence:

1. process.env
2. .claude/skills/serper/.env
3. .claude/.env
4. project .env
5. ~/.claude/.env
