What problem does it solve? Manually checking prices for products, flights, hotels, or tickets is repetitive and easy to forget, and naive alerts often fire on the wrong variant, pre-tax prices, or duplicate offers. This Skill sets up a persistent price watch with a precise item contract and a scheduled cron tick that fetches, normalizes, compares, and alerts only when a real condition is met. ## Core Features & Use Cases - Exact item contracts: Pin the source URL, variant, dates, travelers, seller, and acceptable substitutes so two variants cannot be confused. - All-in price normalization: Separate base price, mandatory fees, shipping, and taxes, and convert currencies only with timestamped rates. - Duplicate suppression and cooldowns: Store the last good observation and alert fingerprint in a state file so replays of the same offer never trigger a second alert. - Use Case: Ask to be alerted when a specific laptop drops below $1,000 all-in; the Skill fetches a live baseline, writes a watch contract to ~/.hermes/price-watches/, and creates a cronjob that checks every 6 hours and notifies you only on a qualifying drop. ## Quick Start Ask the agent to watch a specific product URL and alert you when its all-in price drops below your target amount.
