Flâner is an AI companion designed to help users take small steps outside by creating brief, actionable checklists. The app responds to user inputs about errands or walks and generates a simple plan before prompting users to put their phones away. Unlike typical apps, it avoids engagement loops by omitting points, streaks, or leaderboards, focusing instead on real-world experiences. After an outing, Flâner prompts reflection on what was noticed and enjoyed to cultivate observational skills. The tool is intended for those who struggle with initiating outings or wish to be more present in their surroundings.
A refresh token without an expiry date functions similarly to a permanent password, negating the security benefit of short-lived access tokens. These tokens, defined in technical standards RFC 6749 and 6819, allow attackers prolonged access if stolen, as they can be replayed without user interaction. Common problematic configurations include issuing tokens without expiration, not binding them to a specific device, and failing to rotate them upon use. This setup bypasses security measures like password changes and multi-factor authentication, making stolen credentials highly valuable to attackers.
U.S. import duties are determined by a product's 10-digit HTS code. For goods originating in China, an additional Section 301 tariff of 7.5% or 25% applies to most codes. This guide outlines a method to find both the base and supplemental duty rates from official sources. A significant majority of rated tariff lines are subject to these Section 301 measures. The process involves searching the HTS by product description and checking specific lists for additional duties.
Claude Code employs a hidden orchestration layer using sub-agents and hooks to manage multi-step automation efficiently. Sub-agents are deployed for independent tasks requiring specialized tools, state isolation, or parallel execution to conserve resources. Hooks act as invisible guardrails that enforce security, validate inputs, check permissions, and ensure compliance during operations. This system balances performance with controlled execution to prevent excessive token usage while maintaining safety protocols.
