- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

Free Search Aggregator
Reliable, provider-diverse web search for OpenClaw with high uptime + low operator overhead.
Why use this skill
12 search providers, 6 requiring no API key at all Automatic failover: if one provider fails, the next is tried instantly Quota-aware: tracks daily usage, warns at 80%, skips exhausted providers Task search mode for multi-angle research queries Built-in storage lifecycle (cache / index / report), no workspace clutter Self-healing: health-based smart routing automatically promotes reliable providers Quality optimization: relevance scoring, fuzzy dedup, domain diversity, re-ranking Auto-discovery: probes candidate search engines and SearXNG instances for new sources Self-diagnostic: doctor and setup commands for zero-friction onboarding

Credential model (important)
No mandatory API key โ DuckDuckGo + Bing RSS + Mojeek + Wikipedia work out of the box. API-key providers fail gracefully if key is missing (AuthError โ skip, no quota consumed, no latency): BRAVE_API_KEY EXA_API_KEY TAVILY_API_KEY SERPER_API_KEY SEARCHAPI_API_KEY GOOGLE_API_KEY + GOOGLE_CX BAIDU_API_KEY MOJEEK_API_KEY (optional โ without it uses HTML scraping)
1. Search failover
Default provider order: brave โ exa โ tavily โ duckduckgo โ bing_html โ mojeek โ serper โ searchapi โ google_cse โ baidu โ wikipedia First successful non-empty result returns immediately.
2. Task-level multi-query search
Expands one goal into multiple targeted queries Aggregates + deduplicates results Prefix presets: default: workers=1 @dual ... โ workers=2 @deep ... โ workers=3 + deeper query coverage
3. Quota intelligence
Per-provider daily tracking Real quota retrieval where supported (Tavily, SearchAPI, Brave via probe) Auto concurrency reduction at 80% quota saturation
4. Provider health monitoring
Tracks success rate, latency, and error types per provider over time Computes health scores (success 50%, latency 30%, freshness 20%) Smart ordering: auto-promotes healthy providers, demotes degraded ones View dashboard: python -m free_search health
5. Result quality optimization
Relevance scoring (query-title-snippet token overlap) Enhanced dedup: URL + title similarity (Jaccard threshold) Domain diversity: limits same-domain results (default max 3) Automatic filtering of low-quality results (short titles, missing URLs)
6. Source auto-discovery
Probes all configured providers for availability Scans candidate search engines (Marginalia, Wiby, public SearXNG instances) Validates response format, latency, and result quality Generates recommendations for new sources to integrate Run: python -m free_search discover
7. Managed persistence
memory/search-cache/YYYY-MM-DD/*.json memory/search-index/search-index.jsonl memory/search-reports/YYYY-MM-DD/*.md
Quick commands

Bing RSS (bing_html) โ No key needed
Uses Bing's built-in RSS endpoint (format=rss) โ bypasses bot detection. Works out of the box.
Mojeek โ No key needed (API key optional)
Out-of-the-box HTML scraping. For higher quotas/stability: Register at https://www.mojeek.com/services/search/api/ Set MOJEEK_API_KEY โ automatically switches to JSON API mode
Wikipedia โ No key needed
Multilingual support โ change lang in providers.yaml: wikipedia: lang: it # en | zh | it | de | fr | ja ...
Exa.ai โ API key required
Register at https://exa.ai/ Set EXA_API_KEY Free tier: 1000 searches/month (~33/day)
Google Custom Search โ API key + CX required
Get API key: https://developers.google.com/custom-search/v1/introduction Create search engine: https://programmablesearchengine.google.com/ Set GOOGLE_API_KEY and GOOGLE_CX Free tier: 100 queries/day
Baidu Qianfan โ API key required
Register at https://cloud.baidu.com/ Set BAIDU_API_KEY Best for Chinese-language content
SearXNG โ Self-hosted instance required
Public instances rate-limit server-to-server requests. Use your own: docker run -d -p 8080:8080 searxng/searxng Then in providers.yaml: searxng: endpoint: http://localhost:8080 enabled: true
Post-install self-check
# 1) Confirm provider load scripts/status --compact # 2) Smoke test (uses duckduckgo/bing/mojeek out of the box) scripts/search "openclaw" --max-results 3 --compact # 3) Verify storage paths ls -la /home/openclaw/.openclaw/workspace/memory/search-cache/ | tail -n 5 # 4) Check real quota (optional) scripts/remaining --real --compact
Output contract (stable)
Search: query, provider, results[], meta.attempted, meta.quota Task search: task, queries[], grouped_results[], merged_results[], meta Quota: date, providers[], totals; with --real: real_quota.providers[]
Operator notes
Default mode: workers=1 โ conservative for cost control Use @dual / @deep only for research tasks SearXNG and YaCy are enabled: false by default (self-hosted only) MOJEEK_API_KEY is optional โ provider gracefully falls back to HTML scraping Provider health data stored in memory/provider-health/health.jsonl Discovery results stored in memory/provider-discovery/discovery.jsonl Run python -m free_search doctor after setup to verify everything works Run python -m free_search discover periodically to find new search sources
