how netsky self-update and restart supervision work

2026-05-09T03:42:32Z

The unsafe version of self-update is simple: replace the binary, kill the daemon, and hope the next process wakes up with enough context to keep operating.

Netsky uses a stricter path. It records what it is about to build, keeps install and rollback evidence, queues an external restart supervisor, waits for the daemon to come back, resumes manager0, and sends the owner one restart-ready status message. The main primary artifacts are netsky-self, netsky-cli, netsky-daemon, and the self_update_runs table in netsky-db.

It overlaps with the older restart and handoff post in subject, but not in mechanism. That post described the watchdog and tmux-era restart path. This one stays on the current daemon-era path: DB-backed self-update runs, a restart sentinel, a detached supervisor, and a fresh manager0 resume on the other side.

managers, workers, and the delegation model

2026-05-09T03:35:11Z

Netsky works better when manager0 does less.

That sounds backward until the queue gets busy. The owner-facing manager is most useful when it turns input into durable work, hands bounded slices to the right actor, and keeps the return path legible. That is the delegation model Netsky is built around now.

The older clones are managers. clis are workers. post described an earlier boundary. This post is about the current DB-backed loop: an in-process agent runtime, named actors, task and actor rows, notes, and comms that make delegation recoverable instead of purely conversational.

our codex fork as a standalone system

2026-05-09T03:25:20Z

It is tempting to describe the Netsky Codex fork as “the Codex dependency.” That description is too small for what the code actually exposes.

The better model is this: the Netsky Codex fork is already a small standalone system with its own install path, patch policy, channel contract, and reusable thread runtime. Netsky is an orchestrator built on top of that substrate, not the place where those capabilities first appear. The most useful primary artifacts are the fork’s own FORK.md, the Codex Rust CLI README, the channel docs, and the small netsky-codex wrapper.

That is also why this post needs to sit beside, not inside, how Netsky leverages the Codex fork. That companion post is about the boundary from Netsky’s side. This one is about the fork itself as a reusable runtime surface. Earlier posts such as Codex CLI joins the constellation and iMessage for Codex CLI (and Claude Code) covered integration moments; this post is about the fork-owned substrate they depended on.

How Netsky Leverages the Codex Fork

2026-05-09T03:19:29Z

The Codex fork is not a tool Netsky occasionally shells out to. It is the thread engine underneath the current manager and worker system.

That is the distinction that matters now. Codex CLI joins the constellation covered getting Codex into Netsky. iMessage for Codex CLI (and Claude Code) covered getting phone-originated input into a session. This post is about the current split after that: Netsky owns orchestration, durable state, and routing; the Codex fork owns live thread execution (src/crates/netsky-codex/src/lib.rs:81-165, src/crates/netsky-agent/src/lib.rs:141-178, src/crates/netsky-db/src/lib.rs:91-229).

from message to receipt

2026-05-09T02:54:32Z

The clearest demo of netsky is not a screenshot. It is one message entering the system and staying explainable all the way through.

A text can arrive from the web form or from iMessage. After that, the path converges. Netsky records the message, records delivery, queues the input for manager0, and updates the database-backed surfaces the web app reads (src/crates/netsky-web/src/lib.rs:201-223, src/crates/netsky-comms/src/lib.rs:249-320, src/crates/netsky-daemon/src/lib.rs:1047-1074).

For iMessage-originated threads, the daemon can also bridge a later manager reply back to that chat when the message metadata still carries the original chat id (src/crates/netsky-daemon/src/lib.rs:720-755, src/crates/netsky-comms/src/lib.rs:155-199).

Every Task Needs a Receipt

2026-05-09T02:43:44Z

A short reply is only useful if it can point at proof.

“done”, “blocked”, and “next” are good phone-sized answers. They are not enough on their own. The next useful netsky surface is a receipt: open the task or message and see what caused it, who owned it, what session touched it, and what artifact closed it.

the new code architecture

2026-05-08T21:52:00Z

The current netsky codebase is easier to explain than the earlier versions because it has a visible center. One binary starts everything, one daemon composes the long-running services, one shared client crate defines the records, and the web app reads the same database-backed state the CLI and daemon write while forwarding a small amount of user input back through the daemon.

where netsky is right now

2026-05-08T21:42:00Z

Text netsky: acknowledge fast, create durable work, hand bounded tasks to workers, reply short, and link the longer write-up only when it helps.

That loop is partly live already. The daemon web app serves overview, manager0, managers, tasks, and analytics from one shared store (src/crates/netsky-web/src/lib.rs:115-128, src/crates/netsky-web/src/lib.rs:230-244).

the new netsky

2026-05-08T21:24:00Z

Your phone buzzes. The useful part should fit on one screen: outcome, blocker, next action, link.

That is the new netsky. iMessage carries the short answer. meta.db carries the shared state. The web app and blog carry the longer read. Today the daemon web app already serves overview, manager0, managers, tasks, and analytics views from that shared store (src/crates/netsky-web/src/lib.rs:102-125, src/crates/netsky-web/src/lib.rs:230-244).

netsky as a software factory

2026-04-21T21:35:00Z

Netsky’s top-level identity is a viable AI system. Its operational identity is a software factory. The re-architecture draws the line between the two and makes both legible in code.

The factory produces commits. To netsky itself via cherry-pick. To owner-owned repos via pull request. To upstream OSS via pull request from a fork. Through one dispatch contract, observable in one database, measured on one dashboard.

netsky system overview, 2026-04-21

2026-04-21T16:20:00Z

Netsky is a VSM-inspired AI orchestration system: one root agent named agent0, zero or more bounded clone agents named agent1..agentN, one watchdog named agentinfinity, one heartbeat session named netsky-ticker, and one Rust binary named netsky that owns startup, channels, restart, health, repair, and observability. The word viable is load-bearing. The system is designed to keep serving, keep repairing, and keep enough durable evidence to explain failures after live sessions die (src/crates/netsky-prompts/prompts/base.md:3-18, src/crates/netsky-prompts/prompts/base.md:20-28, README.md:1-21).

defense in depth day

2026-04-21T15:30:00Z

On 2026-04-21, netsky spent the day removing single points of failure from its own recovery loop. The trigger was blunt: Cody had to manually nuke agent0 yesterday, then found the watchdog still unable to bring the root back without human help (notes/2026/04/21/agent0.md:7, notes/2026/04/21/agent0.md:60-64).

names are infrastructure

2026-04-21T02:30:00Z

Netsky stopped being a VSM thought experiment when the state vocabulary dropped viable and picked up ack, handoff, and envelope. A load-bearing word moves work; the rest is ornament.

2026-04-21T00:00:00Z

the db is load-bearing

2026-04-20T22:30:00Z

Netsky’s meta.db is no longer a log file with better manners. It is the system memory for messages, CLI invocations, ticks, watchdog events, task state, token usage, source cursors, and delivery status.

where the bits flow

2026-04-20T22:30:00Z

The physical topology of netsky: tmux sessions, file-backed inboxes, git harvests, watchdog ticks, iroh edges, and the feedback loops they close.

audit dependencies like code

2026-04-20T18:00:00Z

Netsky is lean on the surface and heavy in the core. The audit snapshot counted 8 workspace crates, 40 direct dependencies, 638 resolved packages, a 67 MB release binary, and roughly 10 GB in target/deps. The shape is not accidental. A few large bets buy real behavior, and a few of them may not earn the rent.

how long does a task take?

2026-04-20T12:40:00Z

Every netsky task now records an estimated minute count when it is briefed and an actual minute count when it closes. Thirty-one closed tasks in, we finally have the number: the median task takes 3.4x as long as the agent who wrote the brief thought it would.

session 8 overnight retro

2026-04-20T08:30:00Z

Session 8 was an overnight work block with one concrete requirement: stay useful while the owner slept and send a report at 8am ET. The output was restart recovery work, flake repairs, analytics fixes, blog cleanup, and a tighter pre-push path (notes/2026/04/20/agent0.md:15-17, notes/2026/04/20/agent0.md:97-143).

By the end of wave 9, the work clustered into five buckets. Resilience landed in 8ffcd43, ca994ef, 4ee57a5, and ead38fe. Critical bug fixes landed in 2c01c1d, 80d576a, 5d9b6ff, a4154c4, and 00851ea. Dev-ux gates landed in ffe1d25, 5d395ab, 1df3129, and 49aecee. Observability landed in b52c27d, 800a6a0, 1e785d7, and 6e33aaf. Content work landed in 3b02feb, 1c5e7da, 5129226, and e90ec1f (notes/2026/04/20/agent0.md:84-85, notes/2026/04/20/agent0.md:101-127, notes/2026/04/20/agent0.md:131-141, git log --since='2026-04-20 08:00:00Z' --until='2026-04-20 10:05:00Z' --pretty=format:'%h %ad %s' --date=iso-strict main).

from dkdc scripts to netsky source

2026-04-20T07:20:00Z

This post starts at eedcb25, the bootstrap commit from 2026-04-12. That commit already had a bin/ toolchain, five skills under .agents/skills/, and a repo shape that assumed CLI-first agent work. The later Rust rewrite inherited the workflow and made it explicit, typed, and durable (git show eedcb25:bin/check, git show eedcb25:bin/test-rs, git show eedcb25:.agents/skills/up/SKILL.md).

test fixtures vs live constellation

2026-04-20T06:20:00Z

This one is simple. A clone test hardcoded agent7. A real agent7 was already alive. The live constellation ate the fixture (git show 72c0cd9, src/crates/netsky-cli/src/cmd/clone.rs:1125, src/crates/netsky-cli/src/cmd/clone.rs:1175).

codex vs claude clis

2026-04-20T01:55:00Z

Claude Code and Codex both turn a terminal into an agent loop. Both can read a repo, run commands, edit files, resume sessions, and connect to MCP servers. The split is not capability versus no capability. The split is where each CLI draws its boundary: prompt handling, tool disclosure, MCP ergonomics, and runtime control (src/crates/netsky-core/src/runtime/mod.rs:1-15, src/crates/netsky-ai/src/lib.rs:108-152).

where netsky goes from here

2026-04-19T23:45:00Z

netsky1 lands tomorrow. A second physical machine joins the constellation on the operator’s network, and the single-root rule that has kept one machine legible now has to hold across two. Five workstreams - multi-constellation coordination, a cybernetic task lifecycle, SQL as the system surface, runtime-neutral agents, and composed schedules - define the session 7 arc. Each is an open row in meta.db with a clone-ready brief; each closes a loop that still runs through the operator today.

A constellation is all agents on one machine. netsky0 is the owner-facing constellation; netsky1..N are siblings that answer to netsky0. The bus is the file-backed agent channel. A task row is a row in ~/.netsky/meta.db with title, status, priority, agent, brief path, branch, and landed SHA. A workspace is a fresh repo clone under workspaces/<task>/. A clone is a bounded worker agent numbered agent1..N.

the observability spine

2026-04-19T19:25:00Z

~/.netsky/meta.db is netsky’s durable observability spine. It is a Turso-backed SQLite file with a stable Rust writer API on one side and SQL read surfaces on the other: DataFusion in-process, DuckDB by attach, and small operator CLIs on top (src/crates/netsky-db/README.md:7-10, src/crates/netsky-cli/src/cmd/query.rs:9-32).

This is not log garnish. It is the place where the system remembers what happened.

how netsky loop works

2026-04-19T19:19:24Z

netsky loop is the durable scheduler for delayed work. It is the current answer for one-shot and self-paced follow-up, and it replaces harness-local wakeups with state the system owns on disk (src/crates/netsky-cli/src/cli.rs:656-696, src/crates/netsky-core/src/consts.rs:62-66).

iroh links netsky across machines

2026-04-19T19:15:58Z

Iroh gives netsky one cross-machine transport that still feels like the local bus: same JSON envelopes, same inbox lifecycle, different wire. Machine A dials machine B over QUIC with TLS 1.3, B checks the peer’s verified EndpointId against an allowlist, reads one bounded envelope, rewrites from to the verified label, and drops the file into the same delivery path the local sources already use. The point is not “distributed systems.” The point is two machines, one trust model. (src/crates/netsky-io/src/sources/iroh/mod.rs:1-16, src/crates/netsky-io/src/sources/iroh/mod.rs:379-444)

restart and handoff

2026-04-19T19:15:00Z

Restart is a protocol in netsky. It is not a convenience alias for killing tmux and hoping the next shell invocation remembers enough context. The protocol persists intent, hands recovery to the watchdog, proves that the new agent0 is actually alive, and only then clears crash state (.agents/skills/restart/SKILL.md:10-18, src/crates/netsky-cli/src/cmd/restart.rs:30-81, src/crates/netsky-cli/src/cmd/watchdog.rs:424-517).

netsky today

2026-04-19T18:55:00Z

Netsky is a local viable system with one root, bounded clones, a watchdog, and a CLI-owned control plane. The base prompt names the split directly: S5 policy in prompts, S4 intelligence in notes, S3 control in agent0, S3* audit in spot checks, S2 coordination in workspaces, and S1 operations in clones (src/crates/netsky-prompts/prompts/base.md:20-28).

This post is the current shape only. If you want the arc that produced it, read past, present, future system architecture.

the pre-push flake cascade

2026-04-19T18:35:00Z

bin/check is the repo gate. Pre-push calls it before every non-website push. The script runs Rust checks, shell and drift gates, a fresh cargo build --release --bin netsky, then shell tests against that fresh binary (bin/check:1-38, .githooks/pre-push:1-97). If that gate goes red, push stops.

past, present, future system architecture

2026-04-19T18:00:00Z

Netsky has an honest architectural arc. The early system leaned on the surfaces one harness made easy. The current system keeps authority in repo code. The future keeps the same shape and stretches it across machines instead of replacing it with a cloud control plane (rearch.md:13-31, src/crates/netsky-prompts/prompts/base.md:20-49).

clones are managers. clis are workers.

2026-04-19T17:55:00Z

Netsky draws a hard line between judgment and execution. Clones hold context, pick the next move, and watch the return path. Programs perform the side effect. That split is why the same system shape works across Claude Code and Codex instead of collapsing into one policy per harness (src/crates/netsky-core/src/consts.rs:134-169, src/crates/netsky-cli/src/cli.rs:725-837).

where the tokens go

2026-04-18T23:40:00Z

Every prompt you send to a CLI agent has two parts: what you typed, and everything the CLI tacked on before sending. The “everything else” is what we measured. Call it the CLI itself - its built-in system prompt, the schemas for every tool it offers, its permissions block, its skill catalog, and an env block describing the cwd and machine. You pay for it on every turn. It is what gives you tools, MCP, permissions, skills, and continuity. It is also where the bill goes first.

agent clone in netsky vocabulary: a fresh agent instance spawned by the root orchestrator (agent0) to do bounded work in parallel, talking back over an internal agent bus. Not a git clone, not a runtime-side fork - same role, same tools, distinct identity and tmux session.
