Search Modes
- online: E-commerce sites (Amazon, Walmart, etc.) via Google Shopping
- local: Nearby stores via Google Places API
- hybrid: Both online and local results merged and ranked
- auto: Intelligent mode selection based on query (default)
Parameters
query: Product search query (required)--mode: Search mode (online|local|hybrid|auto, default: auto)--budget: "low/medium/high" or "€X"/"$X" amount (default: medium)--location: Location for local/hybrid searches--preferences: Comma-separated (e.g., "brand:Sony, wireless, black")--max-results: Maximum products to return (default: 5, max: 20)--sort-by: Sort order (relevance|price-low|price-high|rating)--output: text|json (default: text)--country: Country code for search (default: de). Use "us" for US, "uk" for UK, etc.
Budget Levels
- low: Under €50
- medium: €50-€150
- high: Over €150
- exact: "€75", "€250" (or "$X" for US searches)
Output Format
Default (text): Markdown table with product details, ratings, availability, and buy links
JSON: Structured data with all product metadata, scores, and links
Scoring Algorithm
Products are ranked using weighted scoring:
- Price match (30%): Within budget range gets full points
- Rating (25%): Higher ratings score better
- Availability (20%): In stock > limited > out of stock
- Review count (15%): More reviews = more trustworthy
- Shipping/Distance (10%): Free shipping or nearby stores score higher
- Preference match (bonus): Keywords in product description
API Keys Required
- SERPAPI_API_KEY: Required for online shopping (all modes except local-only)
- GOOGLE_PLACES_API_KEY: Only required for local and hybrid modes
Limitations
- API limits: SerpAPI and Google Places have usage quotas
- Real-time data: Prices and availability may change
- Stock accuracy: Online availability reflects last API update
- Local inventory: Store stock not guaranteed via Places API
Error Handling
- Invalid query → Returns error with suggestions
- No results found → Relaxes filters and retries
- API failures → Retry with exponential backoff (3 attempts)
- Missing API keys → Clear error message with setup instructions

pdf-to-markdown
aliceisjustplaying
Convert entire PDF documents to clean, structured Markdown for full context loading. Use this skill when the user wants to extract ALL text from a PDF into context (not grep/search), when discussing or analyzing PDF content in full, when the user mentions "load the whole PDF", "bring the PDF into context", "read the entire PDF", or when partial extraction/grepping would miss important context. This is the preferred method for PDF text extraction over page-by-page or grep approaches.

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y").
