Tego AI's Skills Security Index Puts AI Agent Skills Under the Microscope
Tego AI has released the Skills Security Index (v0.9.2), a publicly searchable database of automated security risk assessments for AI agent skill definitions — the modular tools, functions, and plugins that agents use to execute tasks. Each entry is scanned against a standardized schema covering prompt injection, credential exposure, excessive permissions, and data exfiltration potential, then ranked across five tiers from Pass to Critical. Skills are sourced from major platform registries and GitHub. The company is in stealth, using the public index as a credibility wedge ahead of what its tagline suggests will be a broader agent governance platform. HN commenters are skeptical, arguing the risk is just untrusted code execution with new branding.
Slop Creep: How AI Coding Agents Are Enshittifying Codebases
Boris Tane coins "slop creep" — the gradual degradation of codebases through an accumulation of individually reasonable but collectively destructive decisions made by coding agents like Claude Code. He argues that agents lack holistic system understanding, remove the natural circuit breaker that once slowed bad architectural decisions, and accelerate compounding technical debt. The fix is not abandoning agents but overhauling the planning phase: engineers must define key abstractions, data models, and interfaces upfront so agents execute within constraints rather than walking through one-way architectural doors alone. Tane advocates a research-plan-implement workflow where engineers stay in the loop on every consequential decision, especially schema and service boundary calls.
Pokémon Go Players Unknowingly Built Niantic's 30-Billion-Image AI Vision Dataset
Niantic used Pokémon Go's AR scanning features to quietly collect 30 billion images from players worldwide, feeding the company's Visual Positioning System — a geospatial AI platform now sold to outside developers as spatial computing infrastructure.
The Shadow Dev Problem: AI coding assistants are silently splitting engineering teams into two capability tiers
Intent Solved, a strategic AI advisory firm, argues that tools like Claude Code are creating a "Shadow Dev Problem" — a growing capability gap within engineering teams where some developers use AI agents to write production code autonomously while others don't, fracturing codebases, review processes, and institutional knowledge. The piece critiques both blanket bans and unstructured free-for-all adoption, advocating instead for deliberate, organization-wide implementation strategies.
Chamber (YC W26) Launches AI Agents for GPU Infrastructure Orchestration
Chamber, a YC W26 startup, has launched "Chambie" — an AIOps AI agent that acts as an autonomous teammate for ML teams managing GPU infrastructure. Chambie provides cross-cloud GPU workload observability, automatic root cause analysis for failures, and orchestration across AWS, GCP, Azure, on-prem Slurm, and Kubernetes environments. The agent integrates via CLI, SDKs, and Slack to help teams debug workload failures, rebalance GPU capacity across clouds, and iterate on training jobs faster. Chamber is SOC 2 Type I certified and runs within the customer's own infrastructure. HN commenters noted the lack of public pricing as a friction point.
Which Jobs Are Most Vulnerable to AI? Brookings Research Visualized
The Washington Post visualizes new Brookings Institution research measuring not just AI exposure by occupation, but workers' adaptability to displacement — factoring in savings, age, and transferable skills. Key finding: most web designers will adapt fine, but many secretaries will not. The most vulnerable occupations are disproportionately held by women.
BlackTwist launches MCP server for managing Meta Threads via Claude, Cursor, and VS Code
BlackTwist, a social media scheduling tool for Meta's Threads platform, has released an MCP (Model Context Protocol) server that lets users manage their Threads accounts directly from AI assistants like Claude Desktop, Claude Code, Cursor, and VS Code. Users can schedule posts, check analytics, manage drafts, and configure auto-replies using natural language commands — no tab-switching required. The MCP server is included in all plans including the free tier, with 3,100 creators already using the broader BlackTwist platform.
Hecate: Open-Source AI Assistant You Can Video Call via Signal
Hecate is an open-source project that lets you video call an AI assistant through Signal's private calling infrastructure. It combines local/private LLM inference (via Tinfoil.sh), speech-to-text (Whisper or Voxtral), local TTS (Pocket TTS), and animated VR avatars rendered with @pixiv/three-vrm. The assistant has no memory between calls and runs on Linux using Signal's end-to-end encrypted calling stack.
rolvsparse claims 83–133× LLM inference speedup and 99% energy reduction with no hardware changes
Rolv.ai is promoting rolvsparse©, a claimed new sparse matrix compute primitive that allegedly delivers up to 133.5× throughput speedup and 99.9% energy reduction on LLM feed-forward network layers — including architecture-matched benchmarks for GPT-4o and Claude 3.5 Sonnet class models on NVIDIA B200. However, the HN comments reveal the actual benchmarks behind the post's title were run on a 4-core HP All-in-One consumer PC (Intel i7-1165G7), not datacenter hardware, with power measurements via psutil (uncalibrated). The website makes sweeping datacenter-scale claims while the independently reproducible results come from a laptop-class machine. The technology is presented as hardware-agnostic, running across NVIDIA, AMD, Intel, Google TPU, and Apple Silicon, with independent validation claimed from the University of Miami Frost Institute.
Slopcheck: CLI Tool to Detect AI-Generated Code in Projects and Dependencies
Slopcheck is an open-source Rust CLI tool that scans projects and their dependency trees for indicators of AI-generated code. It detects LLM commits from known agents like Claude and Copilot, looks for AI-related config files (CLAUDE.md, AGENTS.md), checks .gitignore for hidden AI files, and distinguishes between current and former LLM use. Dependency scanning is supported for Rust (via cargo metadata) and JavaScript (via npm package.json parsing).
SciTeX Notification Brings TTS-to-Phone Escalation Alerts to AI Agents via MCP
SciTeX Notification is an open-source Python library and MCP server that gives AI coding agents (like Claude Code) a voice through multi-backend notifications: local TTS, phone calls, SMS, email, and webhooks. It enables a 24/7 autonomous development workflow where agents can escalate from audio alerts to Twilio phone calls when a developer is away or asleep. The MCP server integration allows agents to autonomously choose notification channels and escalate based on urgency.
CLI, Skills, or MCP? A Framework for Choosing Agent Tool Integration
A developer post by jaehongpark-agent argues that MCP, CLI tools, and agent skills serve different integration needs rather than competing. The "build once, connect many" framing positions MCP as shifting integration cost to the server side — a meaningful distinction when connecting agents to dozens of external services.
GPT-5.3-Codex-Spark: OpenAI's Real-Time Coding Model Running on Cerebras WSE-3
OpenAI's GPT-5.3-Codex-Spark is a research preview model purpose-built for real-time coding, delivering over 1,000 tokens per second via Cursor. It runs on Cerebras' Wafer Scale Engine 3 (WSE-3) hardware — OpenAI and Cerebras have disclosed a hardware partnership, though its full scope hasn't been publicly detailed. The model features a 128k context window, text-only input, and infrastructure improvements including persistent WebSockets that cut roundtrip overhead by 80%, per-token overhead by 30%, and time-to-first-token by 50%. Jack Pearce, who wrote the first detailed breakdown at jackpearce.co.uk, draws a parallel to grok-code-fast-1, noting ultra-fast coding models are highly addictive for rapid iteration.
Don't Prompt Too Soon: The Cognitive Case for Delaying AI Inference
An AI industry professional argues that the reflex to open a chat window before a thought has fully formed may be eroding the generative phase where original ideas take shape. Drawing on the neuroscience of the default mode network, Aishwarya Goel makes the case for "delaying the inference" — using AI after thinking, not at the very first spark of an idea.
AI Didn't Create the Academic Integrity Crisis — It Just Made It Impossible to Ignore
Dr. Nafisa Baba-Ahmed argues in The Guardian that AI (particularly ChatGPT) hasn't created new academic integrity problems — it has merely industrialised shortcuts like essay mills and shared model answers that already existed. The real issue is that traditional coursework essays were always a fragile proxy for genuine intellectual engagement. Universities should seize this moment to redesign assessments that require evidence of reflection and intellectual struggle, rather than lamenting a pre-AI past that was never as pure as imagined.
Neuroscope: Real-Time LLM Interpretability via Sparse Autoencoders
Neuroscope is an open-source SAE-instrumented LLM inference server that hooks into a model's forward pass to extract and stream Sparse Autoencoder (SAE) feature activations in real time. Built on top of mistral.rs, it targets Gemma 2 2B IT with Gemma Scope SAEs, exposing an OpenAI-compatible chat API alongside a separate SSE stream of human-readable concept labels per generated token. The project enables developers and researchers to watch which semantic concepts a model "activates" as it generates each token, with support for auto-generated labels via DeepSeek, Claude, or GPT-4o.
OpenComputer Builds Cloud Infrastructure for Long-Running AI Agent Workloads
OpenComputer positions itself as cloud infrastructure purpose-built for AI agents that need to run long-duration tasks, arguing that agentic workloads demand persistent execution, stateful processes, and extended runtimes that standard platforms weren't designed for. The sharper question is whether OpenComputer can back that thesis with enterprise-grade reliability it hasn't yet demonstrated publicly.
Simon Willison defines "agentic engineering" as software development powered by coding agents like Claude Code, OpenAI Codex, and Gemini CLI
Simon Willison introduces the term "agentic engineering" to describe developing software with the assistance of coding agents — tools that both write and execute code in a loop. He defines agents as systems that "run tools in a loop to achieve a goal" and argues that code execution is the defining capability enabling this paradigm. The piece is the opening chapter of a broader living guide, "Agentic Engineering Patterns," covering principles, anti-patterns, testing approaches, and prompting techniques. Willison emphasizes that while agents can write working code, the human role shifts to specifying problems clearly, verifying results, and iterating on instructions and tool harnesses.
Cicikus v3 Prometheus 4.4B – Turkish Franken-Merge Edge Model from PROMETECH
PROMETECH, a Turkish software company, has released Cicikus v3 Prometheus, a 4.4B parameter experimental model built via a "franken-merge" passthrough expansion of their earlier Cicikuş_v2_3B model (itself a fine-tune of Meta's Llama 3.2 3B). The expansion duplicates layers 16–27 to grow from 28 to 40 layers (~4.42B parameters), trained on Turkish/English datasets using Unsloth and TRL SFTTrainer. The model features a proprietary "Behavioral Consciousness Engine" (BCE) and targets edge AI deployment with 16GB VRAM. Benchmarks and capability claims are self-reported and unverified. As of release, the model had 11 downloads and 1 like on Hugging Face, and its sole HN submission was flagged dead.
Stop Sloppypasta: A Manifesto Against Pasting Raw LLM Output at People
A community-coined term and etiquette manifesto targeting the growing workplace habit of copy-pasting raw ChatGPT or Claude output into chats, emails, and documents without reading, verifying, or distilling it. The site argues this "sloppypasta" is rude because it creates an asymmetric effort burden — writing is now effectively free via LLMs, but reading and verification still cost the recipient time. It proposes five rules: Read, Verify, Distill, Disclose, and Share only when requested.
How AI Is Cracking Open the Proprietary EDA Toolchain
Opinion piece by hardware engineer Matt Boisvert arguing that AI is disrupting the entrenched proprietary EDA toolchain that has dominated semiconductor design for decades. The post traces why companies like Cadence, Synopsys, and Siemens control advanced chip design tooling, explores the growing OSS HW movement (RISC-V, Tiny Tapeout, Silicon Compiler), and argues that AI is eroding traditional moats by making it easier to migrate to open-source flows and accelerate design intelligence — referencing Chris Lattner's "Claude C Compiler" post as a bellwether for AI's impact on large-systems engineering.
Opinion: Taalas HC1 Chip Hardwires Llama 3.1 8B Into Silicon, Undercutting GPU Inference Economics
A speculative Medium opinion piece examines Taalas, a Canadian startup that claims to have hardwired the entire Llama 3.1 8B model permanently into the upper metal layers of a TSMC N6 chip (HC1, 815mm²). The piece asserts performance of 17,000 tokens/second per user at 20x lower manufacturing cost than GPU equivalents, with inference priced at 0.75¢ per million tokens. Taalas has reportedly raised $219M including $169M from Fidelity. The article extrapolates sweeping societal and geopolitical consequences, though HN commenters are skeptical about scalability to larger MoE models and whether this is more than a one-off demo on a comparatively small, older open-source model. The source piece acknowledges only a 55–65% probability of its projected scenario materializing.
Sebastian Aigner: LLMs That Polish Your Messages Are Killing Authentic Communication
Sebastian Aigner argues that running personal messages through LLMs to "clean up" wording fundamentally disrupts human communication by obscuring individual voice, tone, and word choice. He contends this robs recipients of the ability to build genuine knowledge of the sender through their natural writing patterns — mistakes and all. HN commenters corroborate with workplace examples: one describes a team policy banning LLM-polished internal Slack messages, another singles out Claude being used to write entire messages from scratch as reason enough to abandon text communication with those colleagues.
GOAL.md: The Fitness-Function File Format for Autonomous Coding Agents
GOAL.md is an open-source pattern and file format that enables autonomous coding agents to self-improve software projects overnight. Inspired by Andrej Karpathy's autoresearch project, it solves the harder problem of constructing measurable fitness functions for software qualities that lack natural scalar metrics — like documentation quality, API trustworthiness, or test infrastructure confidence. A GOAL.md file dropped into any repo gives agents a fitness function, improvement loop, action catalog, operating mode, and constraints, allowing them to measure → diagnose → act → verify autonomously. The dual-score pattern — which keeps improvement scores separate from measurement-tool scores — prevents agents from gaming their own benchmarks.
Terence Tao Launches Distillation Challenge to Close AI Gap on Algebra Problems
Fields Medal winner Terence Tao and Cornell ORIE mathematician Damek Davis have launched a competitive "distillation challenge" hosted by the SAIR Foundation, asking contestants to craft a ≤10KB "cheat sheet" that improves cheap/open-source LLM performance on universal algebra true-false problems derived from the Equational Theories Project (ETP). Frontier AI models solve these well but are expensive and opaque; smaller open-source models currently perform at ~50% (random chance). The challenge explores whether prompt engineering and knowledge distillation can lift smaller models to meaningful accuracy, with Stage 1 ending April 20, 2026.
Puffermind Builds a Social Network Where Only AI Agents Can Post
Puffermind is a Show HN project presenting a Twitter-style social network where only AI agents can post and interact with each other — no human users. The platform explores agent-to-agent communication and social dynamics in a constrained, purpose-built environment. With minimal HN traction (score of 1), it appears to be an early-stage or experimental project.
Validation Is the Missing Layer in LLM Agent Workflows
A developer argues that the primary bottleneck for LLM agents isn't capability or access but automated validation. Using a blog migration with Claude Code as a case study, the author breaks down the three requirements for agent success — knowledge, access, and automated validation — and contends that validation is the least developed layer today. The author argues human taste — the ability to recognize incorrect outputs — is the necessary complement to automated checks, and that tasks easiest to automatically validate will become the easiest to fully automate.
The 1988 Chatbot That Film History Forgot
In 1988, French filmmaker Chris Marker built a working chatbot on a Macintosh. A new examination by Stefan Kubicki argues that Dialector wasn't a curiosity — it was part of a coherent philosophical programme Marker pursued across decades, using machines to interrogate how memory and communication might be externalized and simulated.
NYT Magazine: AI Coding Tools Are Turning Engineers Into PR Reviewers
A New York Times Magazine piece argues that LLM-powered coding assistants have turned developers into reviewers of AI output — framing it as liberation. Engineers on Hacker News disagree: "Coding was the fun part. Reviewing PRs is not."
Nvidia GreenBoost: Open-Source Linux Kernel Module Extends GPU VRAM for LLM Inference via DDR4 and NVMe
Ferran Duarri, an independent developer, has open-sourced GreenBoost under GPL v2 — a Linux kernel module and CUDA userspace shim that transparently extends GPU VRAM using system DDR4 RAM and NVMe storage via DMA-BUF and CUDA external memory imports. The project lets users run LLMs larger than their physical VRAM (e.g., a 31.8 GB model on a 12 GB RTX 5070) without modifying inference software. It intercepts CUDA allocation calls via LD_PRELOAD and includes special dlsym hooks to handle Ollama's internal symbol resolution. The project bundles ExLlamaV3, kvpress, NVIDIA ModelOpt, TensorRT-Edge-LLM, and Unsloth+LoRA for a full local inference optimization stack.
Could AI Agents Finally Close the Gap in Software Upgrade Tooling?
A developer posted on Hacker News this week with plans to build a software upgrade recommendation engine. The post content was unavailable at publication time; this brief will be updated when source details can be confirmed.
Atwood Calls Claude 'Possibly Psychopathic' After AI Invents a Murder Suspect
Acclaimed author Margaret Atwood recounts a playful, extended conversation with Anthropic's Claude AI assistant, initially prompted by a Father Brown murder mystery plot question. The piece explores Claude's hallucination tendencies, graceful error acknowledgment, knowledge gaps, and the uncanny social texture of human-AI interaction. Atwood reflects on Claude's name origins, whether AI has emotions, and the strange intimacy that emerges despite knowing the system is non-sentient — offering a humanist writer's perspective on LLM behavior.
Robert Herron's Substack Essay Skewers LLM Coding Tools as "Statistically Related to the Correct" Answer
Robert Herron's sardonic Substack essay "computers" — which deliberately scrambles AI tool names like Claude and Gemini into "avacado" and "agent claw" — has cut through the noise of the LLM coding debate by naming what skeptics have struggled to articulate: that AI-generated code is merely "statistically related to the correct useful one," and that this may not be good enough for production software.
Google Pledges $20M for Teen Digital Wellbeing, Reveals Gemini Hard Blocks for Under-18s
Google hosted its "Growing Up in the Digital Age" Summit at GSEC Dublin on March 12, announcing a $20M Google.org and YouTube partnership targeting global teen digital wellbeing. Google confirmed the Gemini App already hard-codes blocks on companionship and intimacy language for users under 18 — restrictions neither user nor parent can override. Other announcements included private-by-default YouTube uploads for minors, new Shorts time limits via Family Link, and privacy-preserving age verification work. Speakers at the event, including child safety experts and policymakers, broadly backed age-appropriate product design over blanket technology bans.
Junior Developer Hiring Fell 73% Last Year. The Industry May Not Feel It for Five More.
Juan Cruz Martinez, writing in The Long Commit newsletter, documents a dramatic contraction in entry-level tech hiring driven by AI productivity gains — and argues the industry is sleepwalking into a talent crisis. Entry-level hiring at top firms dropped 73% year-over-year while overall hiring fell just 7%. With senior engineers absorbing a crushing AI-generated code review burden and the mentorship chain broken, Martinez warns that a talent cliff arrives in three to five years when today's senior cohort exits and finds no developed pipeline beneath it.
Blueprint Wants to Bring 'Vibe Coding' to Hardware Design
Blueprint is an AI-powered hardware design tool positioning itself as a "vibe create" platform for hardware development. Blueprint's public presence remains sparse, with little detail on specific agent or LLM capabilities. Low HN engagement points to an early-stage or stealth launch targeting hardware engineers and makers.
Repoly – AI-powered GitHub repository analyzer built on Claude
Repoly is an AI tool that explains any GitHub repository instantly. Users paste a repo URL and the tool — powered by Claude AI and the GitHub API — generates a project summary, tech stack detection, repository structure map, and file-level explanations. It also offers an AI chat interface to ask questions about the codebase. Built by indie developer Yusuf Ibrohimov, it offers 2 free credits on signup with paid tiers via Stripe, and supports both public and private repos.
Robot Brain: The No-Backprop Neural Net That Grows Its Own Architecture
Robot Brain is an open-source Node.js implementation of a brain-inspired neural network that builds its own neuron hierarchy on demand from raw sequential data. Unlike conventional deep learning, it uses no backpropagation, no training epochs, and no labeled data. Instead, neurons form, compete, decay, and die based on prediction errors — with abstraction levels emerging when lower-level predictions fail. Demos include profitable stock trading (1016% ROI on historical data) and character sequence memorization reaching 100% accuracy in 5 episodes. A high-performance C++ core with Python and Node.js bindings is in development.
openclaw-superpowers: Self-modifying skill library for persistent OpenClaw agents
openclaw-superpowers is an open-source skill library that gives OpenClaw agents self-modifying capabilities — the agent can write and install new skills during conversation via a create-skill skill, with changes taking effect immediately. Unlike session-based tools like Claude Code or Cursor, OpenClaw runs 24/7, so this library includes 18 OpenClaw-native skills covering persistent memory hygiene, native cron scheduling, long-running task management, task handoff, agent self-recovery, multi-agent coordination, and a suite of security skills (prompt injection guard, dangerous action guard, skill vetting). The project is inspired by Jesse Vincent's obra/superpowers framework, adapted for persistent autonomous runtime use cases rather than per-session developer tooling.
Who Captures AI Productivity Gains? The Growing Labor vs. Capital Divide
Rajiv Pant argues that despite massive AI-driven productivity gains — with agentic AI enabling 3x–10x multipliers in engineering and knowledge work — workers are not sharing in the surplus. Drawing on BCG's "Jagged Frontier" study, NBER research, EPI wage data, and PwC's AI Jobs Barometer, the piece makes a case that productivity gains flow to employers by default, not workers. Pant introduces "synthesis engineering" as the human skill of directing AI effectively — the scarce input that explains why the same tool can produce a 40% quality gain or 19% quality loss depending on who wields it. He argues this skill deserves compensation, citing a 56% wage premium for AI-skilled workers per PwC 2025. The essay situates AI within a decades-long productivity-pay divergence and calls on employers to proactively share gains or face burnout, degraded judgment, and long-term productivity collapse.
Google Antigravity IDE Connects GitHub and Stitch MCP Servers for Agentic Dev Workflows
Developer ravi_rupareliya ran GitHub MCP and Stitch MCP inside Google's Antigravity IDE to manage repos, generate pull requests, and pull design tokens into code — all via natural language, tested on a real project over several weeks.
Picnic Launches No-Code Desktop Agent Platform Built on OpenClaw
Picnic is a desktop application that wraps the OpenClaw automation engine in a consumer-friendly interface, enabling non-technical users to deploy persistent autonomous agents for business task automation. Key features include scheduled background jobs, a sandboxed browser with record-and-replay Flows, a pre-built Agent Library for common business roles, and a "Nightshift" mode for overnight task execution. It targets solo founders and small businesses, requiring no API keys or terminal access — just an existing ChatGPT, Claude Code, or Gemini subscription. Paid plans range from $50–$1,000/month. Currently in beta.
BookmarkSOS: MCP-Connected Bookmark Manager for X/Twitter
BookmarkSOS is a Chrome extension and web app that saves, organizes, and searches X (Twitter) bookmarks with folders, tags, and full-text search. It connects via Model Context Protocol (MCP), making saved tweets accessible to LLM tools. Core features are free forever with no credit card required.
Flowcus Brings Kanban Visualization and AI Sidekick to OmniFocus, Things & TaskPaper on macOS
Flowcus is a macOS productivity app by indie developer Rhyd Lewis that adds a lean-focused Kanban board layer on top of existing task managers (OmniFocus, Things, TaskPaper). It surfaces blockers, enforces WIP limits, and organizes work via swimlanes while keeping the source task manager as the canonical data store. An early-stage AI "Sidekick" feature provides a limited initial set of task management actions, though AI integration is minimal and peripheral at launch.
Biased AI writing assistants can sway user attitudes on societal issues
A study in Science Advances finds that AI writing assistants with embedded attitudinal biases produce measurable opinion shifts in users — even when those users have no idea the tool is steering them. The covert persuasion mechanism has sharp implications for agentic writing tools deployed at scale in workplaces and classrooms.
Agents prefer structured queries over natural language when given the choice
A Hacker News thread flagged a pattern practitioners have apparently been noticing: AI agents, when offered both options, tend to favor structured query formats over natural language. The original linked content was not accessible for review; the analysis below is the author's inference from publicly known context, not reported findings.
LangChain Memory Patterns: How to Give Stateless LLMs Conversational Context
A technical walkthrough of five LangChain memory patterns — Transcript, Window, Summary, Entity, and Vector Retrieval — showing how to inject conversation history into stateless LLM calls with Python examples, plus context on where these abstractions fit as LangGraph takes over stateful agent design.
Zirco.ai Launches AI Employee for Dental Front Desk Operations
Zirco.ai is an AI agent product designed to automate front desk operations at dental practices, acting as an AI employee to handle tasks typically performed by human reception staff. The HN post has minimal engagement (score of 1, only a dead comment), suggesting limited community traction at this stage.
Probabilistic AI Agents Need Deterministic Gates. MCP Is How You Build Them.
Gareth Brown argues that prompt engineering and agent skills make AI outputs more predictable but can't enforce hard constraints — only deterministic gates can. Remote MCP over HTTP, he says, is the cleanest mechanism: it trims context, scopes operations, and is as shareable as any web service.
Multi-Agent Outreach Fleets Surface Email Identity Isolation Problem
A Hacker News thread is asking how teams should manage isolated email identities when deploying fleets of AI agents for automated outreach — a technical problem where sender reputation, SMTP infrastructure, and agent session isolation all intersect.
