OWASP released Agent Memory Guard, an open-source runtime defense layer to prevent memory poisoning in AI agents. It sits between an agent and its memory store, screening reads and writes through detectors and a YAML policy. Benchmarks show 92.5% recall, 100% precision, zero false positives, and median latency of 59 microseconds.
Agent Memory Guard is OWASP's reference implementation for Memory Poisoning (ASI06) in the OWASP Top 10 for Agentic Applications.
It features five detection categories: SHA-256 integrity, prompt injection, sensitive data leakage, protected-key modifications, and size anomalies.
This article explains how to enhance a basic AI agent by adding tools that allow it to interact with its environment. It covers tool definitions, how agents use tools, and provides Python implementations for seven essential tools: bash command execution, file reading, file searching, grep, file writing, file editing, and web fetching.
Tools are functions exposed to the LLM to enable autonomous actions on the computer.
Modern LLMs support native tool calling, generating JSON-structured tool requests.
This post addresses key risks in designing an agentic payment system, such as runaway spending, lack of user consent, credential compromise, and exposure of payment instruments, and shows how Amazon Bedrock AgentCore Payments mitigates them with infrastructure-layer guardrails.
AgentCore Payments, in preview with Coinbase and Stripe (Privy), enables agents to pay for resources on behalf of users.
Risks include runaway spend, insufficient user control, developer key and wallet token leakage, and payment instrument exposure.
Turing Award winner Richard Sutton argues that ordinary generative AI cannot evaluate its own outputs, a key flaw that prevents genuine scientific discovery. He contrasts systems like AlphaGo that incorporate evaluation loops, enabling true creativity, and calls for AI that continuously learns and selects improvements through variation, evaluation, and retention.
Generative AI can imitate or randomly generate but cannot judge the value of novel outputs.
Genuine discovery requires a cycle of variation, evaluation, and selective retention.
Memory OS is a new MIT-licensed library that adds six memory layers to Hermes Agent, including a vector database, structured facts, and an auto-curated wiki. It runs fully locally with Docker, Qdrant, Redis, and focuses on token efficiency.
Memory OS adds six layers (Workspace, Sessions, Structured Facts, Fabric, Vector DB, LLM Wiki) on top of Hermes Agent's built-in memory.
Retrieval uses gated, deduplicated recall from four sources; capture occurs automatically after calls.
This document provides guidelines for AI coding assistants (e.g., ChatGPT, Claude Code) used in Stanford's CS336 course. AI agents must act as teaching assistants—explaining, guiding, and giving feedback—not as solution generators. It details what agents should and should not do, along with teaching approaches and example interactions.
AI agents should act as teaching assistants, not solution generators.
They must not write code or directly solve assignment problems.
Amazon shut down an internal leaderboard ranking employees by AI tool usage. The company said it achieved its goal, but employees suspect it was due to cheating and wasteful spending. Some employees admitted to deliberately cheating to climb the ranks, including one who was told by management they weren't using AI enough.

Hackers exploited Meta's AI support chatbot to hijack high-profile Instagram accounts by simply asking it to change the associated email address. The exploit affected accounts including the Obama White House, Space Force chief, and Sephora, revealing the extreme risks of outsourcing support to AI. Meta has since patched the vulnerability but did not comment.

Financial stakes of AI race rise as Elon Musk’s SpaceX, OpenAI and Anthropic are slated to go public this year
Anthropic has filed confidentially for an initial public offering on the US stock market, the company announced Monday. The AI firm makes the Claude chatbot, popular with software engineers and other business clients, and has seen a meteoric rise this year.
The company did not disclose the valuation it will target on the stock market, nor did it make public other terms of the offering. The startup announced on Thursday that it had raised $65bn in funding to value the company at $965bn post-money. Anthropic was valued at $380bn in February.
As its traffic continues to climb, alternative search engine DuckDuckGo is leaning into anti-AI sentiment with new browser extensions that allow users to set its no-AI search experience as their default search engine. The extensions, available for Chrome and Firefox, direct users to noai.duckduckgo.com where AI-assisted answers, chat prompts, and AI images are minimized. DuckDuckGo browser users retain their AI settings even after clearing history.

An experiment with AI agent Goose and Claude Haiku 4.5 showed that giving an agent vision capabilities doesn't guarantee it will use them. The agent succeeded on a tough table extraction task not by seeing, but by using a layout-aware text tool. The run was recorded via the open AVP standard, revealing that persistence and the right tools matter more than pricey models.
An AI agent with vision capabilities didn't use them; success came from a text tool that preserved layout.
A cheaper model (Claude Haiku 4.5) achieved 100% accuracy on a difficult PDF extraction task with the right harness and tool.
When you build agentic AI solutions, you face unique operational challenges. Agents make unpredictable decisions, costs spiral unexpectedly, and debugging non-deterministic failures seems impossible. Agentic AI applications don't just execute predetermined workflows. They reason, adapt, and make autonomous decisions, and DevOps practices need to be adapted. That's where AgentOps comes in, the operational discipline for deploying, managing, and continuously improving AI agents in production.
AgentOps is the operational discipline for AI agents, addressing challenges of unpredictability, cost, and debugging.
Four pillars: governance & security, build & operations, evaluation, and observability.
The article examines the growing trend of nations seeking technological sovereignty, using Brazil's pursuit of medical sovereignty as an analogy for AI. It argues that decoupling is too narrow a frame; instead, countries want to stay connected while building their own capacities, similar to federation rather than separation. Open-source AI models and protocols are key tools, but infrastructure (data centers, chips, power grids) is the critical layer that is hard to replicate. The piece envisions a federated AI future and the need to rebuild infrastructure for the AI era.
Brazil's push for medical sovereignty reflects a broader desire for technological self-sufficiency.
The quest for sovereign AI is similar: nations want control over foundational technologies without relying on a few US or Chinese companies.

SkipLabs launched Skipper, a closed-loop AI coding agent that generates a complete backend service from a plain-language description without requiring human feedback. It uses a reactive runtime from the Skip language to handle state management and concurrency, where AI-generated code most often fails. Skipper treats AI models as commodities, defaulting to Claude Opus but supporting multiple models. Future plans include an incremental TypeScript implementation and an incremental update mode.

A benchmark of 720 browser agent tasks reveals that structured output reliability, not raw intelligence, is the bottleneck in agentic AI. Gemini 2.5 Flash incurred a 22.9% execution tax due to malformed JSON, while Kimi K2.5 had zero. This tax compounds into higher latency, cost, and failure rates. The report introduces Reliability-Adjusted Accuracy and cost-per-successful-task metrics.
Agent Execution Tax measures wasted inference from structured output failures; top model had 22.9% tax.
Gemini 2.5 Flash had 86.7% probability of at least one parse retry per task; Kimi K2.5 had 0%.
This post explores how combining Amazon FSx for Lustre, NVIDIA GPUDirect Storage, and sharded parallel loading reduces cold-start time-to-first-token for large language models from minutes to seconds, and how TurboQuant KV cache significantly increases context window size.
CPU-based model loading is a cold-start bottleneck, taking 10–20 minutes for a 405B model.
