What it does
Searxng Search is an agent skill from Luciole-Studio/Misaka-Agent. Free keyless meta-search aggregating 70+ engines.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/searxng.sh`).
It works with Python. The repository describes itself as: A multi-agent research system for the humanities and social sciences. The licence is MIT.
Example prompts
- “/searxng-search”
Requirements
- Python 3
- A Bash shell
- Docker
- A credential in FIRECRAWL_API_KEY
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- If SEARXNG_URL is set and the instance responds, use SearXNG
- If SEARXNG_URL is unset or unreachable, fall back to other available search tools
- If the user wants SearXNG specifically, help them set up an instance or find a public one
What it can do on your machine
Read from SKILL.md and the folder at commit 3bcf7a3. 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
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
curlpython3dockerpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
searxng.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
FIRECRAWL_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Searxng Search loads about 1.7k tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 567 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.

SearXNG Search
Free meta-search using SearXNG — a privacy-respecting, self-hosted search aggregator that queries 70+ search engines simultaneously.
No API key required when using a public instance. Can also be self-hosted for full control. Automatically appears as a fallback when the main web search toolset (FIRECRAWL_API_KEY) is not configured.
Configuration
SearXNG requires a SEARXNG_URL environment variable pointing to your SearXNG instance:
# Public instances (no setup required)
SEARXNG_URL=https://searxng.example.com
# Self-hosted SearXNG
SEARXNG_URL=http://localhost:8888If no instance is configured, this skill is unavailable and the agent falls back to other search options.
Detection Flow
Check what is actually available before choosing an approach:
# Check if SEARXNG_URL is set and the instance is reachable
curl -s --max-time 5 "${SEARXNG_URL}/search?q=test&format=json" | head -c 200Decision tree:
- If
SEARXNG_URLis set and the instance responds, use SearXNG - If
SEARXNG_URLis unset or unreachable, fall back to other available search tools - If the user wants SearXNG specifically, help them set up an instance or find a public one
Method 1: CLI via curl (Preferred)
Use curl via terminal to call the SearXNG JSON API. This avoids assuming any particular Python package is installed.
# Text search (JSON output)
curl -s --max-time 10 \
"${SEARXNG_URL}/search?q=python+async+programming&format=json&engines=google,bing&limit=10"
# With Safesearch off
curl -s --max-time 10 \
"${SEARXNG_URL}/search?q=example&format=json&safesearch=0"
# Specific categories (general, news, science, etc.)
curl -s --max-time 10 \
"${SEARXNG_URL}/search?q=AI+news&format=json&categories=news"Common CLI Flags
| Flag | Description | Example |
|---|---|---|
q | Query string (URL-encoded) | q=python+async |
format | Output format: json, csv, rss | format=json |
engines | Comma-separated engine names | engines=google,bing,ddg |
limit | Max results per engine (default 10) | limit=5 |
categories | Filter by category | categories=news,science |
safesearch | 0=none, 1=moderate, 2=strict | safesearch=0 |
time_range | Filter: day, week, month, year | time_range=week |
Parsing JSON Results
# Extract titles and URLs from JSON
curl -s --max-time 10 "${SEARXNG_URL}/search?q=fastapi&format=json&limit=5" \
| python3 -c "
import json, sys
data = json.load(sys.stdin)
for r in data.get('results', []):
print(r.get('title',''))
print(r.get('url',''))
print(r.get('content','')[:200])
print()
"Returns per result: title, url, content (snippet), engine, parsed_url, img_src, thumbnail, author, published_date
Method 2: Python API via requests
Use the SearXNG REST API directly from Python with the requests library:
import os, requests, urllib.parse
base_url = os.environ.get("SEARXNG_URL", "")
if not base_url:
raise RuntimeError("SEARXNG_URL is not set")
query = "fastapi deployment guide"
params = {
"q": query,
"format": "json",
"limit": 5,
"engines": "google,bing",
}
resp = requests.get(f"{base_url}/search", params=params, timeout=10)
resp.raise_for_status()
data = resp.json()
for r in data.get("results", []):
print(r["title"])
print(r["url"])
print(r.get("content", "")[:200])
print()Self-Hosting SearXNG
To run your own SearXNG instance:
# Using Docker
docker run -d -p 8888:8080 \
-v $(pwd)/searxng:/etc/searxng \
searxng/searxng:latest
# Then set
SEARXNG_URL=http://localhost:8888Or install via pip:
pip install searxng
# Edit /etc/searxng/settings.yml
searxng-runPublic SearXNG instances are available at:
https://searxng.example.com(replace with any public instance)
Workflow: Search then Extract
SearXNG returns titles, URLs, and snippets — not full page content. To get full page content, search first and then extract the most relevant URL with web_extract, browser tools, or curl.
# Search for relevant pages
curl -s "${SEARXNG_URL}/search?q=fastapi+deployment&format=json&limit=3"
# Output: list of results with titles and URLs
# Then extract the best URL with web_extractLimitations
- Instance availability: If the SearXNG instance is down or unreachable, search fails. Always check
SEARXNG_URLis set and the instance is reachable. - No content extraction: SearXNG returns snippets, not full page content. Use
web_extract, browser tools, orcurlfor full articles. - Rate limiting: Some public instances limit requests. Self-hosting avoids this.
- Engine coverage: Available engines depend on the SearXNG instance configuration. Some engines may be disabled.
- Results freshness: Meta-search aggregates external engines — result freshness depends on those engines.

Troubleshooting
| Problem | Likely Cause | What To Do |
|---|---|---|
SEARXNG_URL not set | No instance configured | Use a public SearXNG instance or set up your own |
| Connection refused | Instance not running or wrong URL | Check the URL is correct and the instance is running |
| Empty results | Instance blocks the query | Try a different instance or self-host |
| Slow responses | Public instance under load | Self-host or use a less-loaded public instance |
json format not supported | Old SearXNG version | Try format=rss or upgrade SearXNG |
Pitfalls
- Always set
SEARXNG_URL: Without it, the skill cannot function. - URL-encode queries: Spaces and special characters must be URL-encoded in curl, or use
urllib.parse.quote()in Python. - Use
format=json: The default format may not be machine-readable. Always request JSON explicitly. - Set a timeout: Always use
--max-timeortimeout=to avoid hanging on unreachable instances. - Self-hosting is best: Public instances may go down, rate-limit, or block. A self-hosted instance is reliable.
Instance Discovery
If SEARXNG_URL is not set and the user asks about SearXNG, help them either:
- Find a public SearXNG instance (search for "public searxng instance")
- Set up their own with Docker or pip
Public instances are listed at: https://searxng.org/
