Workflow

  1. Parse query — extract product category from user input
  2. Detect region — default to NL (Ralph is based in the Netherlands). Allow explicit override: /best airfryer de, /best earbuds fr, /best earbuds uk
  3. Search sources — query relevant aggregator for top-rated products via web_search (Brave Search API)
  4. Filter by region — keep products available in selected region
  5. Categorize picks:
    • Top Pick — best overall
    • Best Value — best performance per dollar/pound/euro
    • Budget — solid option under $50/£40/€50
  6. Generate output — 3 picks with summary + link
  7. Date rule: Always use today's actual date (resolved from the system at runtime). Never copy dates from review pages or search results.
  8. Price rule: Show approximate price range from search snippets (e.g., "€120-150"). Use "v.a. €X" for lowest found.
  9. Link rule: Use direct Google search link with full product name: https://www.google.[nl|de|co.uk]/search?q=[product-name]. Region defaults to NL.
  10. Summary rule: Always include 1-2 sentence summary explaining why it's top pick, best value, or budget in English.
  11. Language rule: Always output in the user's language where possible. For NL/BE queries, summaries may be in Dutch or English. For all other regions, use English.
  12. Cache — store results for 6 hours in ~/.openclaw/cache/best-products/

Price-Order Validation (MANDATORY — CHECK BEFORE OUTPUT)

After generating picks, validate price ordering:

  • Budget ≤ Best Value ≤ Top Pick
  • If violated: reorder the categories to match price, or discard the mismatched pick
  • Never output a "Budget" pick that is more expensive than Best Value or Top Pick

Example of a price-order violation:

Budget: Ninja Foodi AF300EU — €149  ← WRONG: more expensive than Top Pick
Top Pick: Philips Airfryer XXL — €130  ← WRONG: cheaper than Budget

Fix: Either swap the category labels to match actual prices, or replace the Ninja with a genuinely cheaper option.

Price-Sanity Checks (MANDATORY — CHECK BEFORE OUTPUT)

Before presenting any pick, verify:

  1. Budget is genuinely budget for the region (NL: ≤ €90, UK: ≤ £75, DE: ≤ €90)
  2. Best Value is cheaper than Top Pick
  3. Budget is cheaper than Best Value
  4. All three picks have real prices — never output "unknown" or leave price blank

If any check fails: do not output that pick. Find a cheaper/different alternative or flag the draft as needing review. If prices cannot be verified: output with a note: "⚠️ Prijzen niet live geverifieerd — check voor publicatie."

Region Detection

Default: NL (Netherlands) — can be overridden per query.

Command Region Retailers Checked
/best [product] NL (default) amazon.nl, Coolblue, MediaMarkt
/best [product] uk UK amazon.co.uk, Currys, John Lewis

Output Format

🎯 /best [product]

📍 [US/UK/DE/FR/IT/ES/NL/BE/PL] — [today's date, e.g. "maart 2026" or "March 2026"]

🏆 TOP PICK
[Product Name]
€[price range] • [Retailer]
[1-sentence summary why]
🔗 https://www.google.[nl|de|co.uk]/search?q=product+name

💎 BEST VALUE
[Product Name]
€[price range] • [Retailer]
[1-sentence summary why]
🔗 https://www.google.[nl|de|co.uk]/search?q=product+name

💶 BUDGET

Caching

  • Location: ~/.openclaw/cache/best-products/
  • Format: {product}-{region}.json (e.g., earbuds-nl.json)
  • TTL: 6 hours
  • Check: Always check cache first; if stale/missing, fetch fresh data
  • To disable/clear: rm -rf ~/.openclaw/cache/best-products/ — cache is optional, not required
  • Privacy note: Cached data is only product names and prices, no personal information

Link Verification (MANDATORY)

CRITICAL: All output URLs MUST be working Google search links. No exceptions.

Rule Requirement
✅ Use Google Search `https://www.google.[nl
✅ Full product name Always use exact name from reviews (e.g., "Philips Airfryer XXL 3000 Series NA342")
✅ Region match Use google.nl for NL, google.de for DE, google.co.uk for UK
❌ No direct retailer links These often block; Google search always works
❌ No markdown links Use raw URL format only: 🔗 https://www.google.nl/search?q=product — never [text](url)
✅ Default to NL Always use google.nl unless user explicitly specifies another region

Verification workflow:

  1. Search reviews → get exact product names
  2. Construct Google search URL with full product name
  3. Verify the product name is accurate from trusted sources (Consumentenbond, Which?, etc.)
  4. Output Google search link — user can click to see current prices

External Endpoints

Endpoint Data Sent Purpose
Brave Search API (web_search) Product search queries only (e.g. "best airfryer nl reviews") Find review pages from trusted sources
Google Search URLs Product names only Generate price comparison links for user (open in browser)
Review aggregator sites None — read-only via web_fetch Extract named product recommendations

No personal data, credentials, or API keys are sent to external services.

Privacy & System Access

  • Search queries: Product search terms only → Brave Search API (via OpenClaw's built-in web_search tool). This is the same as typing a product query into a search engine.
  • Google Search URLs: Product names embedded in links → Google (opens search results in browser)
  • Cache: Writes to ~/.openclaw/cache/best-products/ for 6 hours. Optional — can be disabled by clearing that folder.
  • Timezone detection: Reads system timezone to default to NL. Can be overridden per query (e.g., /best earbuds de).
  • No credentials required: Uses OpenClaw's built-in web_search and web_fetch tools only.
  • No PII: No user identifiers, emails, or personal information processed.

Trust Statement

This skill uses publicly available review data from trusted sources (Wirecutter, RTINGS, Which?, Tweakers, Consumentenbond, etc.) and price data from major retailers (Amazon, Best Buy, MediaMarkt, Coolblue, etc.). No personal data is collected or sent to third parties beyond standard search queries.

Model Invocation Note

This skill can be invoked autonomously when the user types /best [product]. Users can opt out by disabling this skill in their OpenClaw configuration.

Usage Guidance
This skill is internally consistent and doesn't request secrets or install code. Before installing: (1) accept that it will write cached results to ~/.openclaw/cache/best-products/ (you can delete the folder anytime); (2) note the default region is NL (you can override per query); (3) the skill enforces a price-order rule that may reorder or drop picks to maintain Budget ≤ Best Value ≤ Top Pick; (4) future versions may add scheduled checks or external APIs (Keepa, Coolblue) which could require credentials — review later versions for added env vars or background jobs. If any of these behaviors are unacceptable, do not install or inspect the SKILL.md/README again when updating.
Capability Analysis
Type: OpenClaw Skill Name: best-product Version: 1.0.7 The 'best-product' skill is a legitimate product recommendation tool that leverages web search and review aggregators to provide shopping advice. The instructions in SKILL.md are focused on data processing logic, such as price-order validation and regional filtering, and the only filesystem access is for a local cache directory (~/.openclaw/cache/best-products/). No evidence of malicious execution, data exfiltration, or prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description match the runtime instructions: the skill aggregates review sources, price comparisons, and retailer availability across regions. It does not request unrelated credentials, binaries, or config paths.
Instruction Scope
The SKILL.md confines activity to web searches (Brave Search via the platform's web_search/web_fetch), filtering by region, producing three categorized picks, and caching results locally. It explicitly instructs the agent to read the system date and write cache files to ~/.openclaw/cache/best-products/. This file I/O is within the stated purpose but is a persistent artifact the user should be aware of. The skill also enforces a price-ordering rule (Budget ≤ Best Value ≤ Top Pick), which is a functional choice rather than a security issue but can affect recommendations.
Install Mechanism
Instruction-only skill with no install spec and no code files. This is low risk because nothing is downloaded or written by an installer. Runtime behavior is limited to platform-provided web_search/web_fetch and writing a local cache.
Credentials
No required environment variables, credentials, or privileged config paths are declared. The SKILL.md and README explicitly state it uses the platform's web_search/web_fetch and requires no API keys. Planned enhancements (e.g., Coolblue API, Keepa, scheduled price alerts) could later require credentials, but they are not in this release.
Persistence & Privilege
always:false (normal). The skill writes cache files to the user's home (~/.openclaw/cache/best-products/) for 6 hours — a modest, declared persistence. Future planned features mention alerts stored in ~/.openclaw/cache/alerts.json and a daily cron; those would increase persistence/privilege if implemented, but are not present now.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install best-product
  3. After installation, invoke the skill by name or use /best-product
  4. Provide required inputs per the skill's parameter spec and get structured output
