It presents an autonomous customer support and returns agent as an example and recommends hard infrastructure-level controls: cryptographic signatures for database writes, kernel-level sandboxing with gVisor for dynamic code execution, and deterministic gateways for validating I/O, business logic, and data leakage. These controls address prompt injection, unauthorized state changes, credential leakage, and host compromise. ### Source excerpt Building autonomous AI agents that mutate production state requires moving beyond soft system prompts to a robust zero-trust architecture. To secure Google Agent Development Kit (ADK) workflows against prompt injections and malicious execution, developers must implement hardware-backed cryptographic signatures for database writes, kernel-level sandboxing with gVisor for dynamic code, and deterministic semantic gateways for I/O validation. By enforcing these hard security boundaries at the infrastructure level, you can safely deploy multi-tool AI agents without risking unauthorized data manipulation or server compromise. ## Vercel Sandbox now provides 64 GB of storage DevFeed: [Vercel Sandbox now provides 64 GB of storage]() Original publisher: [Read original article]() Author: Luke Phillips-Sheard Published: 2026-09-11T06:00:00Z Content type: release Language: en Sources: [Vercel News]() Topics: [Vercel]() Tags: [agent](), [dependencies](), [documentation](), [sandbox](), [sandboxes](), [storage](), [vercel]() ### AI overview Vercel Sandbox storage has increased from 32 GB to 64 GB for all sandboxes, including those created from managed or custom images and those using the deprecated runtime property. ### Source excerpt Every Vercel Sandbox now includes 64 GB of storage, up from 32 GB.

That creates a problem: generated code shouldn't have access to the user's credentials. We faced that decision when building the v0 Snowflake integration. It lets users connect Snowflake, inspect schemas, query data, and generate applications that run against their warehouses. That generated code has to authenticate to Snowflake, but it is written by a model and runs without human review, and prompt injection can steer it into exfiltrating whatever it can read, so the user's OAuth token should never enter the environment the code runs in. We solved this with a Snowflake request proxy for v0 sandboxes, built on the Vercel Sandbox firewall. The sandbox can run normal Snowflake clients, but the real credential is resolved at request time in a server proxy outside the sandbox runtime. This lets existing Snowflake clients work inside the sandbox without exposing the user's credential to generated code. The harder problem was deciding where the proxy could safely inject the credential. The obvious implementation, replacing a placeholder token wherever it appears, introduces another credential leak. Isolation doesn't protect secrets v0 runs generated applications in isolated sandboxes. Isolation protects the rest of the system from untrusted code, but it doesn't protect secrets inside the sandbox. If a generated app can read a token from the filesystem, that token can be copied into logs, returned in an API response, embedded into generated client code, or sent to another host. Sandbox isolation limits what the application can access, but it does not help once the credential itself is available inside the sandbox. For Snowflake, the credential represents the Snowflake role the user connected with. v0 should be able to help the user explore and build with data they are authorized to access, but generated code should not receive raw provider credentials just because it needs o ## 17,600 Actions: Agent Security Is a Systems Problem DevFeed: [17,600 Actions: Agent Security Is a Systems Problem]() Original publisher: [Read original article]() Author: Jin Kim Published: 2026-08-18T16:00:00Z Content type: opinion Language: en Sources: [Docker]() Topics: [AI Agent](), [Security](), [incident](), [Securing AI](), [Incident response](), [Vulnerabilities](), [Benchmark](), [benchmarking]() Tags: [agent](), [agents](), [ai](), [ai-agent](), [ai-ml](), [benchmark](), [community](), [company](), [dhi](), [docker](), [docker-ai-governance](), [docker-hardened-images](), [engineering](), [evaluation](), [hugging-face](), [incident](), [infrastructure](), [model](), [network](), [openai](), [opinion](), [persistence](), [sandboxes](), [security](), [solutions](), [systems](), [vulnerabilities]() ### AI overview The article argues that AI-agent security is a systems problem, using the OpenAI/Hugging Face incident and its approximately 17,600 attacker actions to show why human approval and ordinary alert triage cannot control persistent, high-rate workloads. It emphasizes constraining authority, credentials, network access, state, and execution across environments. ### Source excerpt The OpenAI/Hugging Face incident exposed a new challenge for AI agent security. 17,600 attacker actions show why AI agent security can't rely on human review.

It emphasizes automation designed to improve reviewer efficiency while preserving human accountability for agent-generated changes. ### Source excerpt The AI SDK is one of the most popular open-source AI projects in the world. It serves over 20 million npm downloads a week and the repo has over 26,000 stars. Maintaining the codebase means tracking four moving targets at once: Model providers: new providers, new capabilities, and new bugs UI frameworks: bindings for React, Next.js, Svelte, Vue, and others Sandboxes: the execution environments agents run code in Harnesses: adapters for Codex, Claude Code, Pi, and others After multiple years of growth, the repo was getting 100+ new issues every month, and when Anthropic's Opus 4.6 model was released, PRs hit an inflection point. By late June, that compounding had accumulated over 1,000 open issues and almost 800 pull requests. That backlog is not a discipline problem. No maintainer, however good, can close that gap by working harder, and because generating code is cheap, it will only grow. Instead of trying to scale ourselves, we built a software factory. Four weeks in, it authors between 25 and 35% of PRs we merge and closes 70-80% of issues. Deciding what type of factory to build Before we built anything, we had to answer three questions: Why our existing approach using agents wasn't enough What level of automation fit a project like the AI SDK How to align automation and human effort to risk Why not add more agents? The best maintainers are already using agents aggressively. Mitchell Hashimoto runs Ghostty with the goal of an agent always working, and encodes every agent failure in AGENTS.md so it never repeats. Simon Willison runs four coding agents in parallel, and review bots like Vercel Agent and CodeRabbit sit on millions of repos. Other maintainers like Daniel Stenberg have opted to block AI-generated submissions to curl. All of it helps, but none of it solves for the core constraint: every one of these solutions still routes every change through one human's attention. We believe that human accountability is still the core of trust in agentic engineering, so ## Ron Efroni on giving agents a deterministic place to run DevFeed: [Ron Efroni on giving agents a deterministic place to run]() Original publisher: [Read original article]() Author: WorkOS Published: 2026-08-05T23:26:44Z Content type: article Language: en Sources: [WorkOS Blog]() Topics: [Nix](), [Deployment](), [Software](), [Shell](), [Docker](), [Meta]() Tags: [architecture](), [declarative](), [deployment](), [developer](), [docker](), [product](), [sandboxes](), [software]() ### AI overview Flox CEO Ron Efroni discusses using Nix-based, hermetic environments to give software agents deterministic places to run.

It also discusses warning signs that AI may be experiencing a financial bubble. ### Source excerpt There's been a fair bit of publicity of the Open AI "rogue agent" that hacked into Hugging Face. This prompted Anthropic to check what their models were up to and, to my complete lack of surprise, discovered three incidents where models had gained unauthorized access to data in other organizations. Simon Wilison concluded: It's abundantly clear now that running evals of cyberattack potential in models is a spectacularly risky business. Every AI lab needs to pay attention to this. Keeping a close eye on what's happening in those sandboxes is crucial It strikes me that this is akin to a virus escaping from a laboratory. It makes clear that the model builders are not putting sufficient controls in place to prevent these lab escapes. They are morally responsible for any consequences of this, and that should extend to legal liability too. The bigger concern however is that this same kind of thing can happen with any organization running open-weight models. Lots of labs playing around with dangerous tools and little idea how to contain them. We are sitting in state that Johann Rehberger describes as the Normalization of Deviance in AI. No big disasters have occurred yet, despite all of these worrying signs. But when does our Challenger-moment appear? ❄ ❄ ❄ ❄ ❄ If the sense that we're in the calm before a storm of rogue AIs worming their way into sensitive software systems isn't enough, there's also knowledge that AI is also a financial bubble. Big advances in technology, whether it be railways or the internet, come with bubbles, and those of us old enough to remember the dotcom bubble see all the signs of that now - only bigger. The problem is that bubbles may be obvious, but the way they grow and pop, particularly when they pop, isn't as clear. The dotcom bubble was widely understood to be one, indeed the chairman of US Federal Reserve talked of irrational exuberance. The trouble is that he said this in 1996, and the bubble took years to grow and burst.

Existing code-review users remain on per-request pricing for 30 days before automatically moving to the new model. ### Source excerpt Vercel Agent pricing is changing. You no longer need to pre-load credits or manage a separate wallet for Vercel Agent. Instead of a $0.30 per-request fee, you now pay a Vercel Token Rate of $0.25 per million tokens, plus provider inference costs at the underlying token rate. The new Vercel Token Rate scales with the actual work each task requires. A quick question costs less than a deep investigation that reads your logs, deployments, configuration, and runtime data, spins up sandboxes, and writes across projects. You pay for the intensity of the work, not a flat fee regardless of what Agent did. The Vercel Token Rate covers: Joining your project context: logs, deployments, configuration, and runtime data Custom model routing and execution across your projects Processing and infrastructure costs It applies to input, output, and cached tokens, and is charged in addition to provider inference costs. For new Vercel Agent users, the Vercel Token Rate begins applying today. If you're already using Vercel Agent for code reviews, nothing changes for the next 30 days. You'll continue on per-request pricing for code reviews through that window, then automatically move to the new pricing, no action required. Learn more about Vercel Agent in the documentation.

Using a snapshot resets its expiration timer, allowing active workflows to keep dependent snapshots available while unused snapshots follow their retention policy. ### Source excerpt Vercel Sandbox snapshots now expire based on when they were last used, not when they were created. Active snapshots stay alive as long as workflows depend on them, while unused snapshots expire on their retention policy. Every time a snapshot is used, its expiration timer resets. This lets you set shorter retention windows without worrying that a snapshot will disappear between sessions, making it safer to build long-running workflows on top of Sandbox persistence.

It standardizes capabilities including skills, sandboxes, sessions, permissions, runtime configuration, compaction, and sub-agents, while allowing applications to switch harnesses without changing their agent flow or user interface code. ### Source excerpt AI SDK 7 introduces HarnessAgent, a single API for running established agent harnesses, including Claude Code, Codex, and Pi. AI SDK has always let you switch models without rewriting your agent. Now you can switch the harness the same way. Write the agent once. Use the best harness available. Today. In 3 months. A year from now. Harnesses manage the components above a model call, including skills, sandboxes, sessions, permission flows, compaction, runtime configuration, and sub-agents. The AI SDK normalizes access to those capabilities through a unified harness abstraction. Initial harness adapters for this experimental release include Claude Code, Codex, and Pi, with more coming soon. Swap claudeCode for codex or pi and keep the same HarnessAgent flow. Every harness runs the agent in a sandboxed workspace, keeping the host environment safe. Both HarnessAgent.generate() and HarnessAgent.stream() return AI SDK-compatible results. If your app already uses useChat or related AI SDK tooling, you can swap in HarnessAgent without changing your user interface code. HarnessAgent is available on the AI SDK canary release.

It recommends running each potentially destructive task in an isolated, disposable Sprite rather than letting the agent execute commands in its own environment. ### Source excerpt Building agents is fun. Rebuilding agents that break themselves... less so. A lot of Fly people are building agents with less of a penchant for self-destruction by teaching their agents to do anything risky in a Sprite. You get an agent that stays alive long enough to actually use its snazzy self-improvement features, and you can allow your agent to try things that would otherwise be battleship-scale footguns. Here's how to do it. Brains vs Hands Your agent would be pretty useless without a shell, because this is where it does agent things. Run the test suite, apply the migration, install the dependency, delete the temp files. Unfortunately, your agent's shell access is also what tends to ruin your afternoon, simply because "delete the temp files" and "delete the wrong files" are one fat-fingered glob apart, and as we're frequently warned, AI can make mistakes. This is why we have sandboxes. But a lot of people default to putting an agent that's going to do potentially scary work in a sandbox. This comes with a long list of tradeoffs that you really don't have to make, because where your agent lives and where it runs code are two entirely separate considerations. PPE for agent workers. The agent process is a loop. It calls a model, reads the response, picks a tool, rinse and repeat. It's a long-lived process that only becomes more competent and less stupid if memory, skills and history persist. So a Fly Machine that sleeps when idle and wakes on a message, a small VPS. Your laptop while you iterate. These are all fine homes for a loop calling an API, which doesn't need a blast shield. It's when you want your agent to execute that things get hairy. bash -c + whatever string the model just produced needs to be run in a padded room. Somewhere where the agent's code can't break itself or anything connected to it. And if your agent is doing more work than you are, you're going to want a whole facility of padded rooms that can be thrown away and rebuilt on a whim.

Drives can preserve agent workspaces, repositories, dependencies, and build outputs, and can be managed through the beta SDK or CLI. ### Source excerpt Vercel Sandbox now supports drives in private beta. Drives are persistent, attachable storage with a lifecycle independent from any sandbox. Create a drive once, then mount it at a configurable path when starting a sandbox. When the sandbox stops, the drive remains available to attach to a later sandbox. Install the beta SDK (@vercel/sandbox@beta) or beta CLI (sandbox@beta), then create and mount a drive: Sandbox Drives are useful for: Keeping agent workspaces across disposable sandboxes Retaining cloned repositories, dependencies, and build outputs Managing data independently from the sandbox lifecycle During the private beta, a drive can be mounted read-write by one sandbox at a time. Sandbox drives should not be used for production data while in private beta. Sign up here to join the waitlist, learn more in the docs, or read the complete guide. Read more [Next page]()
