AWS Bedrock Adds Temporal Policies as AI Agent Control Moves Beyond the Model

AWS this week expanded Amazon Bedrock AgentCore with temporal policies and an open-source policy language called Dogwood, enabling AI agent gateways to evaluate sequences of actions rather than individual tool calls in isolation. The update addresses scenarios where each single action appears compliant but the cumulative pattern violates organizational intent, such as an agent making multiple near-limit purchases. The architectural shift places runtime control outside the model itself, meaning agents no longer rely on faithfully recalling constraints from their prompts. A parallel trend is emerging across the ecosystem, with platforms like Tenable's CyberAgents Exchange decomposing agents into discrete, reusable components including skills, plans, and policies. However, analysts note that runtime policy enforcement still leaves open a deeper question: determining whether the underlying organizational judgment or evidence actually warrants an approval, a problem distinct from simple tool authorization.

How I Protected My Express API from Spam and High AI Costs Using Redis

When I was building my backend API, I realized a big problem: anyone could spam my endpoints. If a user repeatedly reloads a page or hits an endpoint calling an external AI service, it can crash the server or run up high API costs. To fix this, I added Rate Limiting. Here is why I used Redis for it and how I set it up. At first, I thought about saving request counts in a simple JavaScript object: // ❌ Simple in-memory check (Not good for production) const requestCounts = {}; app.use((req, res, next) => { const ip = req.ip; requestCounts[ip] = (requestCounts[ip] || 0) + 1; if (requestCounts[ip]

Developer builds zero-dependency Go clipboard tool for terminal-based text sharing

A developer has released cpynet, a single-file Go binary designed to simplify text sharing between remote servers and local machines entirely from the terminal. The tool requires no signup, no database, and no external dependencies, operating purely through curl commands over standard HTTP. Snippets are stored in memory only and auto-delete either after the first read or when a configurable TTL expires. For sensitive data, the tool supports AES-256-GCM client-side encryption, ensuring the server never processes plaintext. The project was motivated by the friction developers face when using traditional pastebins or clipboard utilities in headless or restricted server environments.
