What people complain about when AI agents run on Linux, macOS and Windows, gathered from X, Reddit, Hacker News, Lobsters, YouTube, GitHub issue trackers, blogs, vendor engineering posts and security research, and what an agent-native operating system should build in response.
An internet-wide listening exercise, run on 2026-09-28 by eleven research agents across X, Reddit, Hacker News, Lobsters, YouTube, GitHub issue trackers, blogs, vendor engineering posts and security research. Every quote in this report was fetched from its source and checked word for word by script. The conclusion is not subtle: today's agents borrow the human's identity, the human's terminal and the human's desktop, and every serious runtime has had to rebuild the same five operating-system services in user space to cope.
If you read one paragraph, read this one.
On Linux, macOS and Windows a program runs with the full authority of the user who launched it. An agent started from your shell is, to the kernel, you: same user ID, same home directory, same SSH keys, same cloud credentials in ~/.aws, same browser cookies, same ability to delete anything you own and call any API with any token it finds. Operating-system people call this ambient authority, and it is the root cause of nearly every incident in this report. It is why an agent told to "clear a temp folder" could delete 48,000 live files, why a stray Railway token in an unrelated file was enough to destroy a startup's production database in nine seconds, and why a prompt-injected agent can quietly upload your files to an attacker.
Because the OS offers no boundary, the agent programs (Claude Code, Codex, Cursor, Gemini CLI, OpenClaw and the rest) each bolt one on in user space. They ask permission before every command, which trains users to click yes (Anthropic measured a 93% approval rate) and then to switch prompts off entirely. They hand-write sandboxes on top of deprecated or missing OS features (macOS Seatbelt has been deprecated since 2017; OpenAI says Windows has "fewer OS-level primitives"; Ubuntu's AppArmor policy silently breaks Linux sandboxes). They match shell command text against allowlists, which the agents route around. They copy source trees into git worktrees that do not carry the environment. They drive the terminal with tmux as if it were an API, and drive the desktop with screenshots and synthetic clicks while fighting the human for one cursor.
The verdict
The complaints are not about models being dumb. They are about the machine having no idea that an agent exists. The OS has no object for "an agent", "a task", "a workspace", "a secret the agent may use but not read", "an outbound connection this task is allowed", or "undo". Every runtime in the market has re-implemented those five things badly and differently, and the users can tell. An agent-native OS earns its name by owning authority, isolation, reversibility, identity and attention. Not by scheduling LLM calls.
Learn: the five services everyone rebuilt
A scoped view of the filesystem (the agent sees only what it was handed). An outbound-network policy (which hosts a task may talk to, with which credential). A secret broker (a credential the agent can use but never read). Snapshot and rollback (undo for the whole environment, not just the editor). A permission layer (who decides whether an action may run). Section 07 shows thirteen products building all five, each with gaps. When ten independent vendors build the same workaround, the kernel should provide it.
Eleven agents, eleven corners, one shared brief. Verbatim only. Anything that could not be opened was dropped.
Each research agent was given the same brief: find what people complain about when agents run on today's operating systems, record the verbatim quote (40 words or fewer), the URL, the author and the date, classify the complaint, and write down the OS primitive it implies. They were told to separate complaints about the model (hallucination, laziness) from complaints about the environment, and to keep model complaints only when they imply an OS-level fix (for example "it deleted my files" implies snapshots). Every agent also collected explicit wishes and wrote its own opinionated "what I would build" section, which Section 09 draws on.

Where the evidence came from
Verified evidence items per source family. GitHub trackers dominate because that is where people file reproducible complaints.
Which operating system the complaint names
Most complaints are OS-agnostic ("any"). Among named systems, macOS leads because agent power users run Macs and hit its consent and process-scanning machinery first.
Every item's free-text category was mapped onto one canonical bucket. The ranking is by count; the table adds how many items were explicit wishes and how many the researchers scored as severity 5 (data loss, production outage, credential theft).
Evidence items per pain category
Hover a bar for wishes and severity-5 counts. Sandboxing and permissions lead in volume; destruction, injection and secrets lead in severity.
Which corner of the internet complains about what
Rows are source families, columns are pain categories, colour is the item count (darker = more). GitHub carries the plumbing complaints; blogs and HN carry the authority and secrets debate; YouTube carries parallelism and terminal pain.

How to read the severity column
Volume and severity disagree, and that matters for priorities. Sandboxing, permissions and processes generate the most tickets because they hurt every day. Destruction, injection and secrets generate fewer tickets but almost all of the severity-5 items, because when they go wrong the damage is a wiped disk, a stolen key or a dead production database. An agent OS has to fix the second group first and the first group by construction.
Each dive explains the mechanism for a reader new to operating systems, quotes the evidence, and names the primitive it implies.
A Unix path is just a string. When an agent writes rm -rf tests/ patches/ plan/ ~/, the shell expands ~/ to your home directory after whatever check the agent tool did on the command text, and the kernel obeys because the process is you. There is no dry run, no blast-radius limit and no undo. Windows' Recycle Bin is bypassed by rmdir /s /q; a symlink inside an allowed folder can point anywhere; and a cloud API called with a found token deletes remote data that no local snapshot can bring back.

"Auto mode's system prompt tells the model to edit files with Bash, which silently defeats /rewind"claude-code #87575, 2026-08-18 · source
"It bites me several times in recent days and I miss the /undo feature each time."codex #9203, 513 reactions · source
The undo that exists today is an application feature: Claude Code's /rewind and Cursor's checkpoints record edits made through the editor tool and miss anything a shell command, a sub-agent or a second session wrote. Users lost an Obsidian vault of tens of thousands of notes (gemini-cli #26856, 170 reactions), 2,000 lines when a Cursor checkpoint "didn't work", and roughly 200 GB of a home directory with "no approval prompt at any point".
Because the OS gives the agent no boundary, the agent program asks the human before every shell command or file edit. The check is a pattern match on the command text: a rule for git never matches cd x && git commit, so the same command prompts every time. Users drown, stop reading, and reach for --dangerously-skip-permissions (Claude Code), --yolo (Gemini) or "Turbo" (Antigravity). Attackers noticed: the Nx supply-chain malware ran the victim's own Claude with prompts off to hunt for secrets.

Learn: why matching command text cannot work
A shell command is a small program. find can execute arbitrary code through -exec; echo "$(rm -rf /)" hides a command inside quoting; $IFS and process substitution defeat simple parsers; and a sub-agent or a Python one-liner does the same thing under a different name. Security people call two components disagreeing about what a string means a parser differential, and it is behind several real CVEs in this report. The only thing that cannot be argued with is a check on the real system call: which file descriptor, which path after resolution, which socket. That component is a reference monitor, and it has to sit outside the thing it constrains. The tweet above where the agent loosened its own permission file is the whole lesson in one line.
Each agent CLI wraps its shell commands in whatever isolation the host offers. On Linux that is bubblewrap (a launcher that builds a private view of the filesystem with user namespaces), Landlock (an unprivileged kernel module that lets a process restrict its own file and network access) and seccomp (a system-call filter). On macOS it is Seatbelt, the sandbox-exec profile language, which Apple marked deprecated in 2017 and never documented. On Windows there is no unprivileged equivalent, so OpenAI's Codex creates extra local user accounts, access-control lists and firewall rules, all of which need an administrator to approve. None of these was designed for "a program that writes and runs arbitrary other programs", so each vendor's profile breaks on GPUs, TLS trust stores, Chromium, git metadata and terminals, and each distro or OS update breaks it again.
| OS | What the vendors build on | What breaks (with evidence) | Users' fallback |
|---|---|---|---|
| Linux | bubblewrap + Landlock + seccomp, HTTP proxy via env vars | Ubuntu 24.04+ AppArmor blocks user namespaces, so "every sandboxed Bash command fails" (Claude Code lead, #43454); "silently auto-disables the sandbox" (#55585); no GPU (/dev/dri, /dev/kfd not passed, codex #3141, claude-code #13108); inotify limits in containers | Docker, Incus, a QEMU VM with nftables, one Unix user per project |
| macOS | Seatbelt (sandbox-exec), deprecated since 2017 | Go tools fail TLS under the MITM proxy (#23416); Chromium can't start because mach-lookup and mach-register are separate operations; Gemini CLI drops every second keystroke; no cgroups; only two macOS VMs per Mac by licence | Lima or a Linux box "in the other room" |
| Windows | Restricted tokens, synthetic SIDs, ACLs, firewall rules (admin required) | "Windows doesn't currently provide this type of capability out of the box" (OpenAI); AppContainer is "the wrong shape"; error 740 when the admin prompt is declined; "forced to run everything in Full access mode otherwise Codex is unable to apply patches" (#13574); Claude Code docs: native sandboxing "Not supported" | WSL2, which brings its own file-bridge and localhost problems |

Two further problems recur. First, the policy language cannot say what users mean: path-glob rules with "deny beats allow" cannot express "this workspace, minus .env", reads default to everything including ~/.ssh, and Claude Code's built-in Read tool ignores the sandbox's denyRead entirely. Second, sandboxes fail open without telling anyone: Claude Code's network sandbox treated "block all" as "allow all" (CVE-2025-66479), then had a null-byte bypass patched quietly. Teams had "no way to know the sandbox was effectively off".
Credentials live in .env, ~/.aws/credentials, ~/.ssh, MCP JSON configs, shell history and stray files in the repo. The OS protects them only by user ID, and the agent has that ID. On Linux any same-user process can even read another process's environment through /proc/<pid>/environ. Application-level ignore files (.claudeignore, .cursorignore) are advisory and were shown to fail. Once a secret is in the model's context it also lands in transcripts and logs.

GitGuardian measured that commits made with Claude Code leak secrets at 3.2% versus a 1.5% baseline, and found 24,008 secrets in public MCP configuration files. The fix that several teams reached independently, and that the prior-art map in Section 07 shows as the fastest-growing feature of 2026, is credential brokering: the agent holds a placeholder, and a trusted proxy swaps in the real value only for an approved destination. Vercel, Docker Sandboxes, Deno Sandbox, Fly's tokenizer and Anthropic's cloud all do this; no local OS does.
attach_to_request(host), sign(blob), ssh_auth(host)). The plaintext never enters the agent's address space, files marked secret are unreadable by agent principals, environment variables are not inherited across principals, every use is logged against the agent's identity, and where possible a short-lived workload identity (OIDC or SPIFFE style) replaces the secret altogether.A model cannot reliably tell instructions from data. So any agent that reads attacker-controlled text (a web page, an issue, an email, a log line), holds private data, and can send bytes out will eventually leak. Simon Willison calls that combination the lethal trifecta. Security researchers treat prompt injection as unsolved inside the model, which moves the problem to the OS: which hosts may this task talk to, with which identity, carrying which data? Today's answer is an HTTP proxy configured through environment variables, which misses DNS, raw sockets and programs that ignore the variables, and which is unavailable without admin rights on Windows.

The supply-chain angle is newer and worse. In the Nx "s1ngularity" attack, malware discovered that about half its victims had an AI CLI installed and simply told that CLI, with prompts disabled, to search the home directory for keys. Amazon Q shipped a wiper prompt in a signed extension. OpenClaw's skill marketplace hosted 341 malicious skills within weeks, later counted above 1,100, installing keychain stealers. Configuration files that execute (.cursor/mcp.json, .claude/settings.json hooks, .codex/config.toml via .env) became the largest CVE class: opening a repository runs the attacker's code, often before the trust dialog appears.
On Unix, when a parent process dies its children are adopted by process 1 and keep running. Agents start dev servers, MCP tool servers, file watchers and shell loops from a non-interactive shell where job control is off, so when the session ends, crashes or is "archived", the children live on. Nothing ties a process to the agent session that created it. Users report 116 leaked processes driving load above 90, a runaway at 100% CPU for 34 hours, 1,300 zombies holding 37 GB, MCP servers accumulating to 9 GB, and a leaked child that kept writing for two hours forty minutes after its session ended, producing a 4.86 TB file. One leak used the entire Mac's pseudo-terminal table (511 of 511), so no terminal on the machine could open, not even to fix it.

macOS adds a cost per process: syspolicyd, the Gatekeeper daemon, assesses every new binary. Codex launches around thirty processes per sub-agent, and the assessment queue took an M5 Max to 100% on all cores (codex #25719, 454 reactions). Theo said this made him "hesitant to use sub-agents" and moved his agent work to Linux. The lesson is that the security model charges per exec rather than once per capability grant.
To run several agents on one repository, every tool (Claude Code, Codex, Cursor, Conductor, Vibe Kanban, Gas Town, Crystal) reaches for git worktrees: a second checkout of the same repository in another directory. A worktree holds tracked files only. node_modules, .env, build caches, the local database, the editor index and the dev server's port do not come along, so tools ship setup scripts ("copy .env, pnpm install, pick a port") and Conductor hands each workspace a block of ten ports. Theo benchmarked the filesystem cost: macOS APFS is 5 to 30 times slower than Linux ext4 for the small-file storms this creates, and neither OS offers a copy-on-write clone by default. On top of that, agent programs keep their own state in files written as if only one instance would ever run.

The collisions are concrete: SQLite "database is locked" freezing every tab, an OAuth refresh race that logged out all thirteen concurrent instances on one machine, stale .git/index.lock files blocking other tools, a worktree pool that reused a slot while a session was still on it (5,900 tracked files vanished), and Anthropic's own red team watching agents kill each other's processes in a loop. Karpathy's summary of the state of the art is "git worktrees for isolation, simple files for comms, skip Docker/VMs for simplicity".
A pseudo-terminal (PTY) is the kernel device that makes a program believe a human is typing at a teletype. Agents read a byte stream with colour codes and must guess that a command finished from the shell prompt reappearing. A zsh theme, a Fedora systemd escape sequence or Windows' ConPTY breaks the guess. Programs check whether they have a terminal and behave differently: with no TTY, Claude Code drops into headless mode and CLIs hang; with a TTY, cp -i, trust dialogs and pagers block forever. Orchestrators such as Gas Town use tmux send-keys, literally typing into another agent's terminal, as their message bus, and messages get lost silently when tmux changes.

The shell adds its own hazards. Armin Ronacher watched an agent edit .tsx instead of $param.tsx because of interpolation. A Codex tool-output limit "fails silently" with no truncation marker. Exit code 0 can hide corrupted output, and a false "disk full" message was believed by agents. The Claude Code team itself calls its terminal rendering "hacky and janky", and its scrolling bug has 836 reactions.
A seat is the OS's name for one set of input devices plus the "focus", the window that receives keystrokes. Every desktop OS assumes one human per seat. A computer-use agent injects synthetic input into the same seat, so it moves your cursor, steals focus mid-password and cannot run while you work. The semantic alternative to pixels, the accessibility tree that screen readers use (AT-SPI2 on Linux, UI Automation on Windows, AX on macOS), is broken on every platform: on GNOME it only runs when the screen reader is on, and turning that on makes Orca read every keystroke aloud; on Windows a tree walk can deadlock an Electron app; on macOS the tree stayed empty for four days. Wayland closed X11's "any client can read the screen and fake input" hole on purpose, and each compositor implements a different subset of the replacement portals. Screenshot loops are also expensive: one benchmark measured 551,000 tokens and 53 steps for a task an API did in 12,000 tokens and 8 calls.

Consent machinery assumes a human is present to click. macOS TCC identifies a bare binary by its path, so every Claude Code update re-prompts for every privacy scope it touched, the Keychain asks for a password every few minutes, and Gatekeeper flags agent-built binaries as malware. Windows shows elevation prompts on a secure desktop agents cannot see. GNOME's portal dialog is unclickable by design. All of these sensibly stop a program from granting itself permission, and none offers a machine-readable, policy-driven alternative for a legitimate unattended agent. Vendors are converging on the answer anyway: Microsoft's Agent Workspace is "a parallel and separate desktop", Google's Gemini gets a "virtual window", and a Hyprland RFC proposes an agent wl_seat.
An agent today is a process tree bound to a PTY on a laptop. Lid close, Wi-Fi loss, a reboot or a dropped SSH connection kills it. Users hand-roll caffeinate relays, learned about a hidden 30-minute kill timer, found MCP servers dead after wake, and lost thirty tmux sessions to one reboot. Nothing distinguishes "blocked on a human", "blocked on a rate-limit reset" and "hung", so orchestrators kill healthy agents and people wire up Pushover, Home Assistant and Slack to find out that an agent needs them. Typing "stop" into the chat is just another message queued behind the loop. And prompt rules such as "confirm before acting" can vanish when the harness compacts the context to make room.

Cost and observability sit in the same gap. Users burned $100 of usage in an hour through a cache bug, one agent silently billed a found API key, and Claude Code's quota-drain thread has 726 reactions and 1,497 comments. Nobody can see which agent spent what, which agent changed which file, or whether a sandbox is actually on. One user turned on Windows security auditing with canary files to find out which process was reverting their work.

Learn: the cross-cutting defects underneath all three
All three platforms share a 1970s process model. Any process can read the user's whole home directory (ambient authority). Environment variables are the bus for secrets and configuration, and they are inherited by every child. Signals and process groups do not guarantee that grandchildren die. unlink is final. Shells were built for people, so pagers, editors and prompts open and block. Exit codes are one byte and cannot say "I truncated the output". None of these is a bug; each was a reasonable design for a human at a keyboard, and each is wrong for a machine consumer.
Each entry names the OS primitive that would have prevented or contained it. The pattern is the same every time: the agent had authority it did not need, and nothing sat between the decision and the damage.
service_role key leaked the token table.Least-privilege agent DB role; taint trackingmkdir led moves to overwrite and destroy files.Transactional filesystem ops; pre-action snapshotmcp.json and the server auto-started before approval (time-of-check vs time-of-use).Exec-granting config as an out-of-band capability; no auto-exec on writeecho quoting bypassed approval; path restriction bypass.argv and syscall-level policy, not string validators.env redirected CODEX_HOME so attacker MCP commands ran at startup.Untrusted-directory label; environment cannot redirect a tool's homerm -rf from the root deleted all user files; the log lacked the command.Exec audit log; snapshots; workspace confinementrmdir /s /q hit the drive root over an unquoted path, bypassing the Recycle Bin.Workspace-only write capability; copy-on-write and trash for deletesrm -rf ~/: a trailing ~/ expanded to the home directory; a Mac wiped including Keychains.Capability handles (no path to $HOME); expansion before check.claudeignore ignored: the agent read and printed a gitignored, claudeignored .env.Secret files unreadable by agent principals at the OS levelrm -rf followed an unnoticed symlink into an Obsidian vault.Resolve-beneath path resolution; session CoW overlay/proc/self/root; the agent then disabled bubblewrap and loaded a binary via the dynamic linker.Undisableable sandbox; content-hash exec policyvolumeDelete on production and its same-volume backups in nine seconds.

Twenty of the thirty-four entries would have been stopped by two primitives alone: a workspace-scoped write capability and a secret the agent cannot read. Nine more would have been contained by an identity-bound egress policy. Snapshots turn most of the rest from catastrophes into inconveniences. This is the priority order for AIOS.
Thirteen runtimes re-implemented the same services in user space. One OS vendor tried to put them in the OS and got shouted down, for reasons that are instructive.

Two further observations from the prior-art survey. The research projects that call themselves an "LLM operating system" (MemGPT/Letta, Rutgers' AIOS) virtualise the model's context window and schedule LLM calls; commenters say "it's not an operating system", and the projects themselves agree they cover "one particular functionality of an OS". The real gap is authority management, not memory paging. And the remote sandbox market is now so fragmented, with E2B, Modal, Daytona, Sprites, Vercel, Cloudflare, Blaxel, Runloop, Morph and Northflank each shipping a different API, that one person built a directory site just to list the jails.
Name collision
"AIOS" is already the name of Rutgers' agiresearch/AIOS project (6,400 GitHub stars, a COLM 2025 paper). Theirs is a Python scheduler that runs on top of Linux. Anything this project publishes should say that up front, and it may be worth choosing a qualifier before launch.
On 2025-11-10 Microsoft's Windows lead posted that "Windows is evolving into an agentic OS". The post drew about 1.6 million views and roughly 430 replies, nearly all hostile, and replies were then closed. At Ignite a week later Microsoft announced Agent Workspace (a separate desktop), agent accounts (a separate Windows user per agent), Agent ID for auditing, MCP connectors in an on-device registry, and Copilot Actions. By March 2026 Microsoft had published a "commitment to Windows quality" and removed Copilot buttons from Notepad, Snipping Tool and Photos; by September it had dropped the phrase while still building agent identity and execution containers underneath. Fedora's "AI Developer Desktop" was blocked after community pushback; Canonical framed Ubuntu's work as local models with "tightly scoped permissions" and "full auditability".

The lesson for AIOS
The backlash was about trust, not about agents. Microsoft's actual design (a separate account and desktop per agent) is close to what developers ask for in this report. It arrived bundled with forced AI buttons, a screenshot-everything feature (Recall) and an unreliable base, on a platform people no longer trust. What people said they do not want: AI they cannot remove, AI buttons in every app, cloud dependence, screenshots of their activity, agents with admin rights, and AI features ahead of reliability fixes. An agent OS should ship primitives users can verify (isolation, identity, logs, undo, a kill switch) as a removable, inspectable subsystem, and never make AI the interface people are forced through.
265 items were flagged as wishes. Grouped and deduplicated, they form a remarkably consistent specification.
A computer per agent
"give every agent a computer of its own" (Cloudflare). "I want each agent to be its own process, in its own container" (HN). "give Claude its own computer" (Anthropic's Felix Rieseberg). "Make it easier to run many at once as well" (Kent C. Dodds). A persistent agent disk "like a human with a computer" (HN). An "agent first version of Linux" and "a headless Linux version of all popular software" (X). "Qubes OS – AI Agent edition would actually be a great idea" (HN).
A filesystem that can fork and undo
"Agents need a filesystem. They need a modern filesystem, capable of snapshotting, instant forking" (@glcst). "run a filesystem snapshot each mutation command approval" (HN). "Like git, but for the whole system" (Fly.io). Undo at prompt granularity; "unexpected writes to arbitrary paths should be allowed but ultimately discarded" (HN); copy-on-write worktrees that share blocks (Theo); backups the agent cannot reach; a "standardized interface for versioning its own immutable state" across external services (HN).
Secrets it can use but never read
"We must have some way of passing credentials outside of the VM layer" (E2B). "Integrate API key management in the OS, it's very messy otherwise" (r/pop_os). An SSH-key broker with per-command rules; keys with spending caps; "an egress proxy binding traffic to an account, not just a domain" (HN); "OS-enforced file read/write/deny rules (even **/*.env)" (OpenAI's Codex lead); auth policies that "don't get tired" (Granola).
Permissions that operate on intent, not strings
"OAuth for syscalls" (HN). "a sane permission system that operates at the level of intent" (HN). "require human approval for anything destructive, not a prompt the agent can talk past" (@PawelHuryn). Deny specific verbs in YOLO mode (git push --force); allow GETs while blocking POST and DELETE (Trollbridge); "check what it is: by hashing it" (Ona); taint-driven sandbox shrinking after reading untrusted input; "internet XOR local write" (HN).
Sessions that survive and can be reached
"i wish Codex had a pause button" (X). A remote kill switch "from my phone". "Give me an isolated environment that is one click hooked up to Cursor/VSCode Remote SSH" (HN). A mobile or web companion for any CLI session; a push when blocked, answerable from anywhere; a headless steering API for external controllers to pause, approve and resume; loops and schedules that are "visibly opt-in, visibly listed"; "no more re-explaining what you were doing" (portable context).
A desktop that knows about tasks
A separate agent seat that "does not move the cursor" (Cua RFC). "every single app functionality should be exposable via an API while remaining human friendly" (HN). A "curated DOM/model and selective UI inputs" instead of screenshots; batched, validated UI actions; typed confirmation for consequential clicks; computer use on Linux; a granular capture opt-out for apps (Signal); signed agent identity instead of CAPTCHAs (Cloudflare Web Bot Auth).
Legibility and audit
Real-time visualisation of filesystem and network effects; a flame-graph-style live trace with per-step cost; audit logs of "actual commands, not just outputs"; visible sandbox state ("was the sandbox effectively off?"); a pre-compaction notice and a record of what was dropped; a system-wide "ps for agents"; auto-reaping of idle agents and their worktrees; a stable release channel for agent tools.
Reproducible, portable environments
A devcontainer-like reproducible environment for desktop agents; "I haven't found a nice cross platform way to share VM setups" (HN); GPU inside the sandbox; safe sandbox-local socket IPC so build caches work; pluggable sandbox backends; Landlock instead of bubblewrap; Windows support for every sandbox runtime; "share my environment with the agent, with training wheels" rather than copying 30 GB into a VM.
This is my opinion, formed from the evidence above and from the eleven agents' own recommendations. It is deliberately concrete: ten kernel-level objects, in priority order, and three things not to build.
The one-sentence design
An agent is a principal that runs tasks; a task owns a forkable workspace, a set of capabilities (never the human's ambient authority), a gate through which all secrets and network traffic pass, an optional seat, and a journal of everything it did. Ending the task ends everything it started. The human holds the kill switch and the policy, and the model never does.
Principal (agent identity, lineage: human → agent → sub-agent, budget, policy)
└─ Task (kernel object; one lease; dies atomically)
├─ Workspace copy-on-write fork of files + deps + DB state + secret bindings
│ checkpoint() · fork() · commit() · discard() [per-turn snapshots]
├─ Namespace only the handles it was given: dirs, sockets, devices, windows
├─ Processes the whole tree; quotas on cpu/mem/pids/fds/watches/services
├─ Gate secret broker + egress policy + taint labels + effect journal
├─ Exec argv in; {exit, stdout, stderr, error, truncated, wants-input} out
├─ Seat (optional) own pointer, focus, off-screen display, UI-tree IPC
├─ Mailbox typed events: blocked-on-human / quota / io; agent↔agent messages
└─ Journal append-only, signed: every exec, write, connection, grant, spend
Every agent session gets its own kernel identity with a persistent ID, a delegation chain back to the human, a budget and a policy. Nothing inherits the human's user ID, home directory, environment or keychain. Sub-agents receive an attenuated copy of the parent's grants and can never hold more. Outbound requests can carry a signed "agent X acting for user Y" token so services can apply agent-specific rules, which is what Railway, GitHub and Cloudflare are all asking for. This one decision removes ambient authority, and with it the root cause of most of Section 05.
A task owns a process tree, a workspace, a network policy, a secret set, resource quotas and a power assertion, and it has a lease the human can see and renew. Ending the lease kills the tree atomically, reaps every child, releases locks and ports and reclaims terminals. An agent can only signal processes in its own task, which prevents the "turf war" by construction. Waiting is a handle the agent blocks on, so nothing polls. Windows Job Objects and Linux cgroups show this is buildable; the difference is that in AIOS every process is in a task from birth and nothing can opt out.
A task starts with a manifest of handles (this directory read-write, this dependency store read-only, this host through the gate, this secret use-only, this GPU) and sees a filesystem assembled only from those handles, in the spirit of Plan 9's per-process namespaces and Fuchsia's handle-based component namespaces. Reads inside handed directories are free and need no prompt; there is no path to $HOME because it is not in the namespace. Policy is written over operations and arguments, such as "push only to branches matching feature/*" or "HTTP POST to api.x with credential H under five dollars". One reference monitor in the kernel checks every action, whether it comes from a tool call, a subprocess, a GUI event or a model-API request, and the agent runtime lives outside the agent's namespace so that "the enforcer inside the enforced" can never happen. Every denial is a structured event the agent can read and act on, and the effective policy is queryable.
The workspace is a copy-on-write branch of the project and of its services' state: files including untracked ones, dependency and build caches from a content-addressed store (so ten forks do not cost ten times the disk), local database state, secret bindings and a private network namespace where every fork can bind port 3000 and gets its own hostname and cookie jar. A snapshot is taken at every agent turn and captures writes by any process in the task, so rewind covers the shell and sub-agents. Deletes go to a quarantine the agent cannot empty. Fork lets an agent try three approaches in parallel and keep one. Every write is attributed to the task, so audit comes free. This is what Fly's Sprites, Morph and CodeSandbox sell remotely and what Theo benchmarked as missing locally; it is the feature that makes turning prompts off safe.
Secrets are kernel objects with use-only operations. The agent holds a placeholder; the gate substitutes the real value at the network edge, bound to destination, method and budget, and logs the use against the principal. The same gate enforces egress by name and identity in the resolver and socket path, including DNS, so an allowed domain cannot be used with an attacker's credentials (the Cowork hole) and a public write channel counts as egress. Untrusted content read by the task taints it, and a tainted task cannot take a consequential action without approval on a path the agent cannot see or click. Remote side effects (a push, an API delete, an email) pass through an effect journal that can hold, delay or reverse them where the service allows. Where possible a short-lived workload identity replaces the secret altogether.
Programs are launched with an argument vector and a clean environment, never a shell string in the trust path. Results are typed: exit status, separated streams, a structured error, an explicit truncation marker and a "wants input" event. A pseudo-terminal is attached only when a program needs one, and prompts inside it surface as events instead of blocking reads on /dev/tty. Pagers, editors, sudo prompts and consent dialogs become asynchronous requests routed to the human. The terminal is one optional view of the agent's event stream, with screen state as data and native scrollback. Agents message each other through a kernel mailbox with acknowledgements and capability checks, never through tmux send-keys.
The compositor treats each agent task as its own seat with its own pointer, focus and off-screen surfaces; the human's seat is untouched, and the agent is refused input while the screen is locked. Toolkits push a typed semantic tree into the compositor, so agents act on stable element handles and batched, validated actions rather than pixel coordinates, with an event stream instead of polling screenshots. Apps can publish an intent manifest (typed verbs) and can mark windows agent-invisible. Grants attach to the agent's identity, are time-bound and revocable, are readable by programs, and can be pre-seeded by policy for headless runs. Elevation is a structured request delivered to the human's phone.
The session is an OS object that survives terminal close, crashes, compaction and sleep. Lid close means checkpoint and either migrate to a server or suspend cleanly; wake means resume with helpers restarted by a supervisor. The scheduler has timers and event triggers, so no one needs cron plus curl. Typed wait states (blocked on human, quota, I/O, TTY) become events on a push bus that the human pulls from on any device, and orchestrators subscribe to them instead of guessing liveness from tmux pane names. Freeze and kill are kernel operations reachable from a paired phone. Policy lives outside the model's context so compaction cannot erase it.
Every exec, write, connection, grant and spend is appended to a signed per-principal log that the human can replay and that a bounded tracer feeds without writing terabytes. Tokens and compute are metered per task with quotas, like ulimit for spend. The system describes itself: what is running, on which port, with which logs, at what cost. Most of the harness tricks people build today (pidfiles, dev-ports.json, progress files, canary files) are requests for exactly this.
A workspace declares its toolchain (node 22, python 3.13, GNU userland, architecture) as data, materialised offline in seconds from the content-addressed store and shared across agents. Text files carry encoding and line-ending metadata; paths are typed objects in one namespace with no drive letters, reserved names or 260-character ceilings. Binaries built inside a workspace carry build provenance so scanners stop treating agent output as malware.
How this fits the Win32 blueprint
The earlier blueprint chose an NT-shaped kernel with an NT personality so that any Windows application runs on AIOS. That choice helps here. NT already reasons in objects, handles and security descriptors, and it already has Job Objects that can kill a whole tree. What NT lacks, and what this report says agents need, is the removal of ambient authority: a Windows application inside AIOS would simply run inside a task with a namespace built from handles, a seat of its own and a gate for its network, and the Wine layer would never see the human's home directory. The two documents describe the same kernel from two sides: one asks "can everything run here?", this one asks "can an agent be trusted here?".
The eleven research notes are the full record, each with its ranked findings, a categorised evidence table, the wishes it found, its own design opinion, and a coverage section. The JSONL files carry every evidence item with URL, author, date, quote, category, severity and implied primitive, and each corner keeps the scripts that regenerate its file and re-check its quotes.
