serper-search

serper-search is a skill for Claude Code, Codex from agentscope-ai/ReMe. It costs 53 tokens per session (412 once invoked), scanned A, original, Apache-2.0.

A search skill that retrieves current public web results through the Serper search service. It is intended for coding agents that need information or links not available in local files or project APIs.

In plain words
What is it for?
Searching for current information, general web sources, and specific URLs. It helps agents refine queries, inspect returned results, and summarize sources without exposing the search API key.
Why use it?
It gives an agent a defined way to search the web when outside information is needed. It also instructs the agent to prefer authoritative sources and verify important claims.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

serper-search scanned grade A with 1 finding 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 9d 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.

What it actually says

Use Serper whenever external web search is needed. Prefer local files and project APIs when they already contain the required information.

Rules

  • Do not use the built-in WebSearch tool.
  • Do not expose the API key in answers, logs, committed fixtures, or browser/client code.
  • Prefer authoritative and primary sources in the returned results.
  • Refine the query when freshness, date, company, product, or source type matters.

API

  • Endpoint: POST https://google.serper.dev/search
  • Auth header: X-API-KEY: $SERPER_API_KEY
  • Content type: application/json
  • Required body: {"q":"query text"}

Curl

curl -s --location "https://google.serper.dev/search" \
  --header "X-API-KEY: $SERPER_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{"q":"apple inc"}'

Response Use

  • Prefer organic results for normal search answers.
  • Use searchParameters to confirm the query actually sent.
  • Treat credits as usage accounting.
  • Verify important claims against the linked source rather than treating snippets as complete evidence.
  • Summarize results with source titles and links; do not copy large passages from snippets or pages.

Failure Handling

  1. If DNS/network fails, report it as an environment/network issue and retry only when external network is available.
  2. If authentication fails, report that SERPER_API_KEY is missing or invalid without printing its value.
  3. If results are irrelevant, refine the query with names, dates, locations, or source domains.

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.
