What it does

Serper Search is an agent skill from agentscope-ai/ReMe. Search the public web through Serper instead of the built-in WebSearch tool. Use when an agent needs current information, general web sources, or URLs not available from local files and project APIs. SERPERAPIKEY is available in the environment.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering. The repository describes itself as: ReMe: Memory Management Kit for Agents - Remember Me, Refine Me. The licence is Apache-2.0.

When your agent uses it

  • An agent needs current information
  • General web sources
  • URLs not available from local files and project APIs

Example prompts

  • “/serper-search”

Requirements

  • A credential in SERPER_API_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  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 it can do on your machine

Read from SKILL.md and the folder at commit c1de31a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • google.serper.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SERPER_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Serper Search loads about 459 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 184 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~459

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

serper-search
description
Search the public web through Serper instead of the built-in WebSearch tool. Use when an agent needs current information, general web sources, or URLs not available from local files and project APIs. SERPER_API_KEY is available in the environment.

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

bash
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.
