ide

Run Unix commands, background jobs, and structured filesystem operations from the iii engine, on the host or forwarded into a sandbox microVM.

Notice: renamed from `shell`

This worker used to be called shell. Only its identity changed, so nothing that talks to it needs to be rewritten:

worker name, binary, Cargo package and registry entry: shell → ide (iii trigger compose::add worker=ide, npx skills add iii-hq/workers --skill ide)
source directory: shell/ → ide/; dependents pin ide in their iii.worker.yaml
unchanged on purpose: the shell::* function ids (shell::exec, shell::fs::*, shell::pty::*, …), coder::*, the shell::changed trigger type, the shell configuration entry, the data/shell/ data directory and the #/ext/shell console page

Install

iii trigger compose::add worker=ide

Sandbox-targeted execution and shell::fs::* forwarding need the iii-sandbox worker; iii trigger compose::add worker=ide does not pull it in. To surface shell::* to LLM agents, pair with iii-directory:

iii trigger compose::add worker=iii-sandbox worker=iii-directory

Running

The binary needs no required environment variables — it boots against a local engine with pure defaults. The full operator surface:

Knob	Default	What it does
`--url` / `III_URL` env var	`ws://127.0.0.1:49134`	WebSocket URL of the iii engine. The CLI flag wins over the env var.
`--config`	`./config.yaml`	Seed config sent as `initial_value` on FIRST registration only; the stored value wins afterwards (see Configure).
`--version`	—	Print the worker version (also registered with the engine as worker metadata).
`RUST_LOG` env var	`info`	Log filter (tracing `EnvFilter` syntax, e.g. `RUST_LOG=ide=debug,info`).

If the engine is unreachable at boot, a pre-connect probe (run detached, so it never delays startup) logs one ERROR ("engine unreachable at : — is the iii engine running? Set --url or the III_URL env var...", logging the resolved host/port rather than the raw URL) and the worker keeps retrying in the background every 2s — it never exits, so supervised deployments recover as soon as the engine is up.

A --config seed file that exists but fails to parse (for example, one still carrying 0.6.x keys) aborts boot rather than silently falling back to the permissive built-in default — see Upgrading to 0.7.0. A genuinely missing file still falls through gracefully to the stored value or the built-in zero-config default.

Configure

Settings are managed through the central configuration worker. On boot, the shell worker registers its schema (id shell) and fetches the live value over RPC — that live value is the authoritative config, not a local file. The optional --config flag (default ./config.yaml) provides the initial_value sent on first registration only; once registered, subsequent boots pull the stored value from the configuration worker. When the config changes, the worker hot-reloads the security policy and fs backend automatically (see Hot-reload).

The worker refuses to start unless fs.host_roots is set, or fs.allow_unjailed: true is explicitly opted in, because an unset root exposes the whole host filesystem behind only the advisory denylist.

By default, mkdir/chmod/write reject modes carrying setuid/setgid/sticky bits (the top octal digit, e.g. 4755) with S210, since they are a privilege-escalation primitive when the worker runs as root. Set fs.allow_special_bits: true only if your workload genuinely needs them.

max_timeout_ms: 120000       # foreground exec hard cap; per-call timeout_ms is clamped to this
max_bg_timeout_ms: 0         # host bg job hard cap in ms; 0 = unbounded (foreground uses max_timeout_ms)
default_timeout_ms: 30000    # applied when the caller omits timeout_ms (code default 10000)
max_output_bytes: 1048576    # 1 MiB; stdout/stderr past this set *_truncated
env:
  inherit: true              # forward the worker's env to children; per-call dangerous keys still blocked
  allow: [PATH, HOME, LANG, LC_ALL, TERM]  # forwarded when inherit is false; has no effect on per-call `env` (deny-only — dangerous keys never settable)

# Command policy is deny-only: allow/ask policy lives in the approval-gate.
# denylist_patterns are advisory regex over argv.join(" "), a tripwire for
# catastrophic mistakes only, NOT a security boundary. Command-shaped
# patterns are anchored to argv[0] (tolerating a sudo/doas/nohup/env/timeout
# wrapper) so `grep -rn shutdown src/` is not rejected but `sudo shutdown -h
# now` still is; argument-shaped ones (rm -rf /) stay unanchored. See the
# shipped config.yaml for the full patterns.

Zero-config default

With no --config file and no value stored in the configuration worker, the worker seeds a built-in default on first registration — so it boots with nothing configured (database-style). That built-in default is the shipped config.yaml: unjailed (fs.allow_unjailed: true, empty host_roots), env forwarded, deny-only exec with a catastrophic-only denylist (kept in sync by a unit test). Unjailed means shell::fs::* and shell::exec's per-call cwd operate against the real filesystem, confined only by fs.denylist_paths — matching shell::exec itself, which has never been confinement-based. coder::* is the one exception: it falls back to its own default roots (engine workspace cwd + /tmp) whenever fs.host_roots is empty, so it stays reasonably scoped even under the zero-config default. Set fs.host_roots if you want shell::fs::*/cwd jailed too. If the stored value is later nulled, the worker does not silently fall back to this seed: boot fails closed and a hot-reload keeps the last-good config. A config that is present but leaves fs.host_roots unset (without fs.allow_unjailed: true) also fails closed — the failure mode only disappears once you explicitly opt in, one way or another.

Host shell::exec is not a security boundary: any interpreter (sh, node, python3) can construct a denylisted token at runtime and bypass the regex. Run untrusted input with target: { kind: "sandbox", sandbox_id }, which forwards through the iii-sandbox microVM. The denylist still applies on top of either backend.

Per-call `cwd`, `env`, and `stdin` (host target)

shell::exec and shell::exec_bg each accept optional fields so an agent can scope a single command to a directory, set specific env values, and feed it standard input without wrapping everything in sh -lc (which would blur what the argv actually was):

cwd (string): the working directory for this one call. It is confined to the fs jail exactly like shell::fs::* paths — jail-relative when fs.host_roots is set (else absolute), canonicalized, and required to resolve inside a jail root and miss denylist_paths. A cwd that escapes the jail returns S215; one that doesn't exist or isn't a directory returns S211/S210. Omit it to use the configured working_dir (unchanged default).
env (object of string→string): per-call environment values. Deny-only, like the exec/fs command policy: a key may be set to any value except an exec-hijacking key — PATH, IFS, HOME, every LD_*/DYLD_* variant, and other loader/lookup-path and interpreter startup-file keys (GCONV_PATH, BASH_ENV, ENV, PYTHONSTARTUP, PERL5OPT, RUBYOPT, NODE_OPTIONS, …), which are rejected unconditionally. env.allow plays no role in this gate at all — that list's only job is which vars get forwarded from the worker's own environment when env.inherit is false (see Configure); it has nothing to do with what a per-call override may set. Supplying a dangerous key rejects the whole call with S210 (the offending key is named); the env is never silently dropped. A per-call value overrides the value that would otherwise be forwarded for that key. So an agent can do NODE_ENV=test freely, but can never inject PATH, HOME, or LD_PRELOAD.
stdin (string): written to the program's standard input, which is then closed (EOF). Use it to feed tee, patch, cat, or any stdin filter instead of a shell heredoc. Omit it and stdin is /dev/null.

All three fields are host-only. The sandbox::exec protocol does not forward cwd/env/stdin, so a sandbox-targeted call that supplies any of them is rejected with S210 rather than silently ignoring it. Omit them and behaviour is identical to prior versions.

Quick start

npm install iii-sdk

import { registerWorker } from 'iii-sdk'

const iii = registerWorker(process.env.III_URL ?? 'ws://127.0.0.1:49134')

const result = await iii.trigger({
  function_id: 'shell::exec',
  payload: { command: 'echo', args: ['hello'] },
})

console.log(result)

The example runs on the host. The same payload retargets at a microVM with target: { kind: 'sandbox', sandbox_id: '' }. The other entry points are shell::exec_bg, shell::status, shell::kill, shell::list, shell::config-status, plus the shell::fs::* family (ls, stat, read, write, grep, sed, mkdir, rm, chmod, mv).

Functions

Function	Purpose
`shell::exec`	Run a command in the foreground; returns stdout, stderr, exit code, and timing. Blocks until exit or timeout. Accepts optional host-only `cwd` (confined to `fs.host_roots` when set, else absolute), `env` (deny-only, gated by a dangerous-key denylist), and `stdin` (string piped to the program's stdin, then EOF) — see Per-call `cwd`, `env`, and `stdin`.
`shell::exec_bg`	Spawn a command as a background job; returns `{ job_id, argv }` immediately. Accepts an optional caller-chosen `job_id` on host and sandbox targets so you can subscribe before starting the job. Host-targeted jobs run until they exit or `shell::kill` terminates them — unbounded by default, and capped only when the operator sets a positive `max_bg_timeout_ms` (default `0` = unbounded), after which a runaway job is killed and its status becomes `killed`. Sandbox jobs honor `timeout_ms`. Same optional host-only `cwd`/`env`/`stdin` as `shell::exec`.
`shell::status`	Fetch one job's full record: state, exit code, and captured stdout/stderr. A missing id — one that never existed or aged out past `job_retention_secs` — returns an `S211` ("no such job") error.
`shell::list`	Enumerate current jobs as lightweight summaries; argv, stdout, and stderr are redacted.
`shell::kill`	Terminate a running background job by `job_id`. Sandbox jobs cannot be hard-killed: the record flips to `killed` but the in-VM process runs until its `timeout_ms` (or `sandbox::stop`).
`shell::config-status`	(operator/automation only — not agent-callable) Report the last hot-reload outcome: `last_outcome` (`applied`/`rejected`), `last_error`, and `rejected_reloads` (count since boot). A rejected outcome or non-zero count means a stored config was refused and shell is enforcing an older policy than the central store. Takes no arguments.
`shell::fs::ls`	List a directory's entries with structured metadata, sorted by name and paginated: `page` (1-based, default 1), `page_size` (default 500, max 2000); the response carries `total`, `page`, `page_size`, `has_more`.
`shell::fs::stat`	Read one path's metadata (size, mode, symlink flag).
`shell::fs::mkdir`	Create a directory, optionally with missing parents. Returns `{ created, path, already_existed }`.
`shell::fs::rm`	Remove a file or directory, optionally recursive. Returns `{ removed, path, was_present }`.
`shell::fs::chmod`	Change a path's mode, and optionally its uid/gid. Returns `{ entries_changed, path, recursive }`. (Breaking: field renamed from `updated` to `entries_changed`.)
`shell::fs::mv`	Rename or move one path within the jail. Returns `{ moved, src, dst, overwrote }`.
`shell::fs::grep`	Recursive regex search across a tree; returns structured matches. Keys are singular `include_glob`/`exclude_glob`; the case flag is `ignore_case`.
`shell::fs::sed`	Regex find-and-replace across one file or many.
`shell::fs::write`	Write a file. Simplest form passes inline string `content` (host target only): `{ path, content: "file text" }`, with `mode` (octal, default `"0644"`) and `parents: true` to create parents. A `ContentRef` object in `content` instead streams large/staged payloads through an SDK channel (temp file + atomic rename) and is required for sandbox targets — an inline string on a sandbox target returns `S210`. Batch form: pass `files: [{ path, content, mode?, parents? }, ...]` (host, inline per file) to write several files in one call; the response then carries per-file `files: [{ path, bytes_written }]`. A single-file write leaves `files` empty and returns `{ bytes_written, path }`. Supplying both single `path`/`content` and `files` returns `S210`.
`shell::fs::read`	Stream a file's bytes out through an SDK channel. For an inline read on the web surface, use the `harness::fs::read_inline` wrapper instead.

Every shell::fs::* call accepts the same optional target as exec, so host and sandbox share one wire shape.

Code surface (`coder::*`)

The shell worker also serves the coder::* code-file functions (the former standalone coder worker, folded in). They are agent-ergonomic, structured file operations that share shell::fs::*'s jail when fs.host_roots is set. When it's empty (the shipped default — see Zero-config default), the two surfaces diverge: shell::fs::* becomes fully unjailed, but coder::* falls back to its own default roots (engine workspace cwd + /tmp) instead — it never runs fully unjailed, regardless of fs.allow_unjailed.

Function	Purpose
`coder::info`	Discover the jail: roots, caps, response budgets, exclude/non-accessible globs. Call first.
`coder::read-file`	Windowed reads (`line_from`/`line_to`), `stat` probe, byte-budgeted full reads, and multi-file batch reads.
`coder::search`	Literal/regex content + path search with context lines, bounded by match/byte budgets. `respect_gitignore: true` skips what `.gitignore` hides; `fuzzy_paths: true` ranks path matches quick-open style, best first.
`coder::list-folder`	Paginated single-folder listing.
`coder::tree`	Recursive depth- and per-folder-bounded directory snapshot.
`coder::create-file` / `coder::update-file` / `coder::delete-file` / `coder::move`	Batched create, line/regex edits, delete, and atomic rename/move.

Roots come from fs.host_roots (with the cwd+/tmp fallback noted above); protection globs come from code.non_accessible_globs in the shipped config.yaml's code: block — the same list shell::fs::* enforces. coder::* returns its own C2xx codes. Since 0.10.0, shared C2xx and S2xx numbers mean the same failure class; coder-only failures are called out explicitly below:

Code	Meaning	fs twin
`C210`	Malformed input: bad payload, illegal line numbers, overlapping ops.	`S210`
`C211`	Path not found, permission denied, matched `non_accessible_globs`, or under `fs.denylist_paths` — deliberately ONE code and wording for all four, so a caller can't probe for a denied path's existence.	`S211`
`C213`	`create-file`/`move` saw an existing target and `overwrite=false`.	`S213`
`C215`	Path escapes every allowed root, lexically or through a symlink (jailed mode only).	`S215`
`C216`	Underlying I/O error.	`S216`
`C218`	File exceeds `max_read_bytes`/`max_write_bytes`.	`S218`
`C220`	Path resolves inside a configured root but outside the per-call `scope_root` the session is scoped to.	`S220`
`C221`	Optimistic whole-file save conflict: the file no longer matches `expected_revision`; no bytes were written.	n/a

No separate install: iii trigger compose::add worker=ide brings the whole surface.

Terminal sessions (`shell::pty::*`)

The console's terminal runs on this worker: shell::pty::open starts a persistent host PTY, write sends base64 keystrokes, resize follows the pane, attach/detach survive a reload (buffered output replays from a sequence number, out of a 2 MiB ring buffer), and close terminates the session. These are console plumbing — flagged internal and trace_hidden, so their spans stay out of the default trace view; one span per keystroke buries the work worth reading.

A session runs the user's login shell by default, or the program a caller names:

Field on `open`	Meaning
`program`	Program to run instead of the login shell, resolved on PATH. A caller that can open a login shell can already run any program by typing it, so this is reach, not privilege — it is what lets a session BE one program, with no shell around it.
`args`	argv for `program`; ignored without it.
`env`	Extra environment for the session. Deny-only exactly like `shell::exec`'s per-call `env`: an exec-hijacking key (`PATH`, `LD_`, `DYLD_`, `BASH_ENV`, ...) refuses the whole call, and so does a key that is not a variable name (`[A-Za-z_][A-Za-z0-9_]*`) — a key like `PATH=/tmp/evil` would otherwise carry its own assignment past the `PATH` rule.

cwd resolves through the same jail as shell::fs::*, so what it can reach is whatever that config says:

fs.host_roots set: a session can only start inside a configured root.
fs.allow_unjailed: true with fs.host_roots empty (the shipped default): there is no root to be inside, and cwd reaches the real filesystem, held back only by fs.denylist_paths.

Either way this bounds where a session STARTS. A login shell can then cd anywhere its user can, which is the point of a terminal.

Output goes to a browser-registered console handler and nowhere else: iii::-ui::pty-output::console-. The -ui segment is not pinned to this worker's own page — a worker that runs its own program in a session serves its own console page, and therefore its own handler — but the shape is enforced, so a session can never be pointed at an arbitrary function on the bus.

Each pane carries a font-size stepper (8–40 px, 14 by default; Ctrl or ⌘ + scroll does the same). The size is a browser preference rather than a worker setting — the same person reading the same engine from a laptop and from a wall display wants two different answers — so it is stored per browser and read by every terminal the console renders, this worker's panes and the agent-CLI pages alike. A change refits the pane, which resizes the PTY through the ordinary shell::pty::resize path.

Taking a session back (`shell::pty::adopt`)

The reconnect token is what proves a caller opened a session, and a browser that loses its storage loses the token while the program keeps running — an agent still working in a workspace nobody can reach. shell::pty::adopt is the way back, under two rules that keep it from being a way in:

The session must be unattached. A terminal someone is watching is never taken from them; only one nobody holds.
The new output handler must name the same console page as the old one. The browser id may differ — that is the point — but iii::claude-ui::… cannot adopt a session whose output went to iii::pi-ui::….

Credentials rotate on adoption, so whatever the previous owner still held stops working, and an in-flight retry of the old attach cannot resurrect it. shell::pty::sessions is how a page finds its orphan: every session reports ui, the console page it belongs to (a page, never a browser), whether or not anyone is attached.

shell::pty::sessions lists live sessions with their program, cwd, status, last sequence number, replayable frames and bytes, and current output target. No credentials: it exists to separate a terminal that shows nothing because no output arrived from one whose frames the browser dropped.

Two surfaces, one contract

shell::fs::* and coder::* are two views of the same filesystem, served by this one worker under ONE policy: the same jail (fs.host_roots), the same unjailed opt-in (fs.allow_unjailed), the same protected globs (code.non_accessible_globs), the same operator denylist (fs.denylist_paths), and — since 0.10.0 — the same error-code semantics (equal digits, equal meaning) and the same existence redaction (a denied path reads exactly like a missing one on both surfaces).

They differ in ergonomics, and each operation has a twin:

Task	`coder::*` (agent-ergonomic)	`shell::fs::*` (byte-level)
read	`coder::read-file` — inline text, windowed, batched	`shell::fs::read` — streams bytes via channel
create	`coder::create-file` — batched inline text	`shell::fs::write` — inline or streamed, modes
edit	`coder::update-file` — line ops + regex, post-apply echoes	`shell::fs::sed` — regex replace across files
delete	`coder::delete-file` — batched, per-entry errors	`shell::fs::rm` — single path
list	`coder::list-folder` / `coder::tree` — paginated, noise-filtered	`shell::fs::ls` — single directory, paginated
move	`coder::move` — batched, cross-root copy+delete	`shell::fs::mv` — single path
search	`coder::search` — budgeted, context lines	`shell::fs::grep` — raw matches
introspect	`coder::info` — mode, roots, caps, globs	`shell::fs::stat` — one path's metadata

Conventions (hold these when adding functions to either surface):

Batching: coder::* operations are batched with per-entry error isolation. shell::fs::* point operations are single-path (write and sed are the historical exceptions).
Naming: coder::* uses verb-noun kebab (read-file); shell::fs::* uses the unix tool name (read, ls, mv). Follow the surface you are extending.
Errors: one { code, message } envelope; C/S codes with equal digits mean the same failure class (see Errors). Redaction: never let a denied path read differently from a missing one.
Discovery: coder::info is the agent-facing contract report. shell::config-status (reload health), shell::workspace::* (console working-directory picker and the explorer's chunked byte reads) and shell::turns::* (per-session change history and its revert) are operator/console control plane, not agent tools.
Sandbox: shell::fs::*/shell::exec accept target: sandbox; coder::* is host-only.

Custom trigger types

Trigger type	Fires when	Payload to subscribers
`shell::job-finished`	A background job finishes, is killed, or fails. A binding filtered by `job_id` also receives a retained terminal result when registered after completion.	`{ job_id, argv, status, exit_code, started_at_ms, finished_at_ms, duration_ms }`
`shell::changed`	A file or directory under the watched root changes.	`{ path, kind, root, dir }`

Background job completion (`shell::job-finished`)

Choose a job ID, register a completion subscription, then start the job with shell::exec_bg using that same ID. The subscription tells you when the job ends without polling shell::status.

shell::exec_bg accepts an optional job_id on both host and sandbox targets. It must be a string containing at least one non-whitespace character. Omitting it or passing null generates a job- ID, preserving the existing behavior. A supplied ID is reserved atomically before the command starts or the sandbox execution request is sent. If that ID already belongs to a running job or a retained finished job, the request is rejected without executing the command or changing the original job.

IDs belong to one worker process. Generate a fresh, globally unique ID for every execution, even after an older record has been pruned. This field is not an idempotency key: resubmitting an ID does not resume or return its original job.

The trigger's binding configuration accepts one field:

Field	Type	Default	Meaning
`job_id`	Optional string	No filter	Receive the named job's completion. Omit it to receive future completions of all background jobs in this worker process.

A filtered subscription also receives the result if its job has already completed, including a job that finished before shell::exec_bg returned. Registration and live completion are deduplicated for that binding. An unfiltered subscription receives future completions only; it does not replay existing records.

For a harness agent, generate a new ID, such as job- followed by a UUID. Call engine::register_trigger with that ID and wait for registration to succeed before starting the job. Save its returned subscription_id for cleanup if execution cannot start. Omitting function_id registers a wake for the calling session; sibling workers instead register the trigger with their own handler as its target:

{
  "trigger_type": "shell::job-finished",
  "config": { "job_id": "<new-unique-job-id>" },
  "once": true
}

Then call shell::exec_bg with the same ID and await its response:

{
  "job_id": "<new-unique-job-id>",
  "command": "pnpm",
  "args": ["build"],
  "cwd": "/path/to/project"
}

If shell::exec_bg fails before starting a job, no completion event will be emitted for that attempted job. Remove the subscription by calling engine::unregister_trigger with the saved harness subscription ID:

{ "id": "<returned-subscription-id>" }

A session whose policy forbids unregistration, including a leaf sub-agent, can bound the wake when registering it with "lifecycle": { "expires_in_ms": 600000 } (ten minutes in this example). An expiry notification reports that the wake ended; it is not a job completion event.

The existing flow also works: call shell::exec_bg without job_id:

{ "command": "pnpm", "args": ["build"], "cwd": "/path/to/project" }

Then call engine::register_trigger with the generated job_id from the response. A job that already completed is replayed while its record remains in memory:

{
  "trigger_type": "shell::job-finished",
  "config": { "job_id": "<returned-job-id>" },
  "once": true
}

The completion event contains:

Field	Type	Meaning
`job_id`	String	The ID returned by `shell::exec_bg`.
`argv`	Array of strings	The command and arguments as spawned.
`status`	String	`finished`, `killed`, or `failed`; never `running`.
`exit_code`	Integer or `null`	The process exit code, when available.
`started_at_ms`	Non-negative integer	Job start time in milliseconds since the Unix epoch.
`finished_at_ms`	Non-negative integer	Completion time in milliseconds since the Unix epoch.
`duration_ms`	Non-negative integer	Elapsed milliseconds, clamped to zero if the clock moved backwards.

The event excludes stdout and stderr. Read captured output with shell::status using { "job_id": "" }.

Replay and output retrieval depend on the job record remaining in this worker's memory. Finished records are pruned after job_retention_secs (default 3600, one hour after completion), and a worker restart loses them. Subscribe and retrieve output within that window; a pruned record cannot be replayed and shell::status returns S211. Delivery is best effort, without retries or a durable event history.

Live change feed (`shell::changed`)

The worker registers a custom trigger type backed by a system-level directory watch (FSEvents on macOS, inotify on Linux, via the notify crate). A subscriber names the directory in its binding config:

{ "type": "shell::changed", "config": { "path": "/some/dir" } }

Paths the root ignores — git-ignored inside a repository; data/, config/, .iii/, node_modules/ and the root .gitignore outside one — are not delivered unless the binding also sets include_ignored: true. A watch on a project root would otherwise fire on the engine's own data/observability and data/session-manager writes, i.e. on the subscriber's own transcript. The workspace UI opts in to count them.

Every fire carries the binding's registered metadata and namespace back to the bound function, the same way the engine's own trigger types do — the harness relies on it to match a wake to its __binding.

Each registration starts one recursive watcher; unregistering (or the console GC'ing a closed tab's binding) tears it down. config.path goes through the same path policy as every coder::* call — jail containment (fs.host_roots), the operator denylist, canonicalization — and must be a directory: watching a tree is a read of every filename under it, so a path you can't read is a path you can't watch.

The payload is lean — { path, kind, root, dir } with kind ∈ created | modified | deleted, path relative to the watched root, and dir true when the path is a directory (a subscriber that opens files must skip those; deleted paths can't be probed and report false). A subscriber that wants content asks coder::read-file; one that wants the diff asks git.

Semantics:

Catches every writer — an agent calling coder::*, a shell::exec command's side effects, or an editor outside the engine entirely. Nothing is coupled to the harness and no other worker is involved.
Coalesced: raw OS events storm, so each watcher batches per path in a 200 ms window; kinds merge toward the visible outcome (a create plus the write that fills it is created, a deletion supersedes what came before, a create-after-delete is created). .git internals are filtered — the visible outcome arrives as worktree events of its own.
Best-effort fan-out: events fire with no reply expected; a slow or absent subscriber never delays anything.

The console explorer page binds this on its browsed root: the tree and git panels refresh live, a clean active buffer follows the disk (a dirty one keeps the user's edits), and the last written file follows the writer into view as a diff — git baseline in a repo, empty baseline for created files, the page's last-seen content otherwise. Hidden segments, noise directories (target, node_modules, dist, build, …) at any depth, and build/temp artifact extensions never steal the view.

Hot-reload

When the configuration worker pushes an updated config, the shell worker swaps in the new security policy and fs backend atomically. A few things to know:

Each call executes against one consistent runtime snapshot; there is no mid-call config change.
Already-running background jobs are not retroactively re-checked when the policy tightens — they continue under the policy that was active when they were spawned.
A reload that widens the jail (for example, clearing host_roots) succeeds but is logged as a privilege change.
If the incoming config is invalid or unsafe, the worker keeps the last-good runtime and logs an error. The rejection is also surfaced through shell::config-status (a rejected outcome with a non-zero rejected_reloads count), so the divergence between the central store and the policy shell is actually enforcing is detectable instead of silent. Rejections are kept last-good and not retried (re-fetching returns the same bad value), so they will not retry-storm.
At boot the reconcile against the configuration worker is fail-closed: the worker refuses to start (and exposes no functions) if it cannot confirm the authoritative config, so it never serves a possibly stale security policy.

Errors

Returned error bodies carry a stable code field. Denylist rejections come back as a plain message (command matches denylist: ) rather than an S-code.

Code	Meaning
`S200`	In-VM execution failure on a sandbox target.
`S210`	Invalid request: non-absolute path, empty command or pattern, bad octal mode, malformed payload, `sandbox.enabled: false` on a sandbox-targeted call, a `cwd` that is not a directory, an `env` key in the dangerous-key denylist, `cwd`/`env`/`stdin` supplied on a sandbox target (host-only), an inline string `content` on a sandbox-targeted `shell::fs::write`, or both single `path`/`content` and `files` on `shell::fs::write`.
`S211`	Path not found, permission denied, matched the protected globs, or under `fs.denylist_paths` — ONE code and wording for all four (redaction: a denied path reads exactly like a missing one). Includes a `cwd` that does not exist.
`S212`	Wrong file type for the operation (for example, a file where a directory was expected).
`S213`	Path already exists.
`S214`	Directory not empty (non-recursive `rm`).
`S215`	Path (or a per-call `cwd`) escapes the `fs.host_roots` jail — exclusively a confinement escape; denylist and permission-denied fold into `S211`.
`S216`	Generic shell-internal failure: host spawn error, channel error, or a bad engine response.
`S217`	Invalid regex passed to `grep`/`sed`.
`S218`	`fs.max_read_bytes` / `fs.max_write_bytes` cap exceeded.
`S300`	Sandbox VM boot failed (needs a virtualization host: Apple Silicon or `/dev/kvm`).

Sandbox-forwarded fs::*/exec errors can also surface engine codes verbatim instead of collapsing to S216: S001–S004 (sandbox lifecycle), S100–S102 (image/VM/resource), S300, and S400. Branch on the specific code where relevant; only an unrecognized engine code falls back to S216.

Upgrading to 0.10.0

BREAKING: three coder::* error codes renumbered to align with the S2xx scheme (equal digits now mean the same failure class on both surfaces): already-exists C217 → C213; too-large C213 → C218; outside-session C218 → C220. Consumers branching on the old numbers must update; the approval-gate's jail-scope allowlist ships the matching change in the same release wave.
BREAKING: shell::fs::* existence redaction. Permission-denied, protected-glob (code.non_accessible_globs), and fs.denylist_paths rejections now return S211 with the same "not found or not accessible" wording as a missing path, instead of S215. S215 is now exclusively a jail-confinement escape. Callers must not distinguish "missing" from "denied" — that distinction was an existence-probing side channel.
coder::* is permissive when unjailed. With the explicit opt-in (fs.allow_unjailed: true, empty fs.host_roots) the coder surface now follows the same deny-only policy as shell::fs::*: absolute paths anywhere on the host, the cwd + /tmp fallback roots demoted to relative-path anchors, and the harness-selected working directory trusted as the anchor. fs.denylist_paths now applies to coder::* in every mode. Jailed deployments (explicit fs.host_roots) are unchanged. coder::info reports the effective mode.

Upgrading to 0.8.0

BREAKING: allowlist removed. The command allowlist is gone — the shell is deny-only now (see Configure); allow/ask policy lives entirely in the approval-gate. Any stored config still carrying the key, including the inert allowlist: [] written by older seeds, fails closed at boot with a migration hint. Rewrite the stored value to drop it:
```
import { registerWorker } from 'iii-sdk'
const iii = registerWorker(process.env.III_URL ?? 'ws://127.0.0.1:49134')
const { value } = await iii.trigger({ function_id: 'configuration::get', payload: { id: 'shell' } })
delete value.allowlist
await iii.trigger({ function_id: 'configuration::set', payload: { id: 'shell', value } })
```
If you seed from a --config file instead, just delete the allowlist: [] line.
BREAKING (fresh installs only): the fs jail is unjailed by default. The shipped config.yaml now sets fs.allow_unjailed: true with empty fs.host_roots — shell::fs::* and shell::exec's per-call cwd operate against the real filesystem by default (see Zero-config default). This only affects a genuinely fresh install or a config that gets nulled — an existing deployment with an explicit fs.host_roots already in its stored config is unaffected; the stored value always wins over the seed. To keep the old jailed-to-/tmp behavior, set it explicitly:
```
fs:
  host_roots: [/tmp]
```
The per-call env override is deny-only. env.allow no longer gates which keys shell::exec/exec_bg's per-call env may set — only the hardcoded dangerous-key list does (see Per-call cwd, env, and stdin). This is a pure widening: nothing that worked before now fails, and no stored config needs a rewrite. env.allow keeps its other job (forwarding when env.inherit is false) unchanged.

Upgrading to 0.7.0

BREAKING: env config keys renamed and nested. The top-level inherit_env and allowed_env keys are replaced by one env block — no legacy aliases:
```
# 0.6.x                                # 0.7.0
inherit_env: true                      env:
allowed_env: [PATH, HOME, LANG]          inherit: true
                                         allow: [PATH, HOME, LANG]
```
The old keys are rejected at parse with a migration hint ("config keys removed in 0.7.0: inherit_env -> env.inherit ..."), because serde would otherwise ignore them silently and boot with env forwarding OFF. A stored configuration value still carrying the old keys makes the worker fail closed at boot; rewrite it via configuration::set (id shell) with the nested shape. Sequencing matters: update the binary FIRST, then the stored value — writing the new shape while 0.6.x is still running makes the old worker hot-reload it, ignore the unknown env block, and silently stop forwarding env until restart. A half-migration (nesting the OLD key names under the new block, e.g. env: { inherit_env: true }) is also rejected — env denies unknown fields — rather than silently falling back to the wider default allow list. A --config seed file carrying any of these removed keys now aborts boot rather than warning and falling back to the permissive built-in seed; only a genuinely missing seed file falls through gracefully.
BREAKING: fs.host_root (single-root alias) removed. The 0.6.x one-entry alias for the jail root is rejected at parse with a migration hint ("config key removed in 0.7.0: fs.host_root -> fs.host_roots (one-entry list)"). Replace it with the list form:
```
# 0.6.x                                # 0.7.0
fs:                                    fs:
  host_root: /srv/app                    host_roots: [/srv/app]
```
Same fail-closed rationale as the env keys: serde would otherwise ignore the stale key and the worker would see no jail configured at all.
BREAKING: code.base_path/code.base_paths removed from the schema and REJECTED at parse. They were inert even before removal — the code resolver has taken its roots from fs.host_roots since the coder merge — but this is a hard migration: "never had an effect" is not an exception. A stored value still carrying either fails closed with a hint naming both keys, same as every other removed key. Set the jail once via fs.host_roots.
The one-shot coder→shell config migration is removed. 0.7.0 no longer folds a legacy standalone-coder configuration entry into the shell value at boot, and the hidden migrated_from_coder marker field is REJECTED at parse rather than silently tolerated. Boot also no longer probes configuration::get for the coder entry, so the "configuration 'coder' not found" WARN retries at startup are gone. Two distinct upgrade scenarios:
- An install that ALREADY has a shell entry (it went through the fold under 0.6.x, so the entry carries migrated_from_coder: true) now fails closed at 0.7.0 boot with a migration hint, instead of silently parsing past the marker.
- An install with ONLY a standalone coder entry and NO shell entry at all has nothing to reject — it still boots 0.7.0 with the generic permissive /tmp dev seed for shell, silently, because there is no stored shell value to fail closed on. The old coder roots and protected globs are NOT carried over. Boot 0.6.x once first (it performs the migration and writes the shell entry) before upgrading to 0.7.0 to avoid this.
--version added, and --url/III_URL and RUST_LOG are now documented (see Running).
Unreachable-engine boot is loud: one ERROR naming the host/port and the fix hint, instead of only the SDK's silent retry WARNs. The probe runs detached so it never delays boot.
Every config field now carries a schema description, so the console configuration UI documents each knob inline.
Command-shaped denylist patterns tolerate a wrapper prefix (sudo/doas/nohup/env/timeout [duration], optionally path-qualified): sudo shutdown -h now trips the tripwire again.

Upgrading to 0.4.0

0.4.0 is a breaking release. Migrating from 0.3.x:

shell::fs::chmod response field renamed updated → entries_changed; read entries_changed. Inbound legacy { updated } from an older engine still deserializes (serde alias), but new consumers should read entries_changed.
mkdir/rm/mv gained structured fields (path/already_existed, path/was_present, src/dst/overwrote) alongside the original boolean. Additive: existing readers of created/removed/moved keep working.
Configuration moved to the central configuration worker (database-style) with hot-reload. --config is now a first-boot seed only; the live value from the configuration worker wins once an entry exists. --manifest was removed (the interface is collected live).
New read-only shell::config-status reports the last hot-reload outcome. Operator/automation only; it is denied to agents.
Error envelope: the S-code is now the top-level wire code. Every S-coded failure returns { "code": "S211", "message": "no such job: ..." } with the S-code as the top-level code. Previously the code was buried — handlers returned the {code,message} JSON stringified into message under the generic invocation_failed code. Consumers that branched on code == "invocation_failed" or parsed the embedded JSON out of the message must update to read error.code directly.
Host background jobs are unbounded by default. A host-targeted shell::exec_bg job runs until it exits or shell::kill terminates it — long installs, builds, dev-servers, and tails are not killed. To force-kill a runaway host bg job, set a positive max_bg_timeout_ms (new operator config field, default 0 = unbounded; separate from max_timeout_ms, which bounds foreground shell::exec); a job that exceeds it is killed and its status becomes killed. Sandbox jobs still honor timeout_ms.
Per-call env denylist broadened. The always-rejected key set now includes HOME and loader/lookup-path keys (LD_*, DYLD_*, GCONV_PATH, …) and interpreter/shell startup-file keys (BASH_ENV, ENV, PYTHONSTARTUP, PERL5OPT, RUBYOPT, NODE_OPTIONS). These are rejected even if listed in allowed_env. LD_*/DYLD_* are matched by family prefix, so a loader variable not in the explicit list is still rejected. Note that HOME is in the default allowed_env for the worker's own forwarded env but is not settable per-call.
Sandbox-forwarded fs/exec errors can now surface engine S-codes that 0.3.7 collapsed to S216 — e.g. S001–S004 (lifecycle), S100–S102 (image/VM), S300, and S400. Branch on the specific code where relevant.

Troubleshooting

fs.host_roots is empty ... refusing to start unjailed: set fs.host_roots to at least one directory, or set fs.allow_unjailed: true.
S215 path escapes the fs jail roots on a path inside the jail: a symlink in the path resolves outside the jail. Resolve it yourself, or move the target inside a jail root.
S300 on a sandbox target: the host cannot boot microVMs. Sandbox execution requires Apple Silicon or /dev/kvm.
Worker never connects: the engine is not running or not bound on the configured --url. Start the engine first; the default WebSocket port is 49134.
config keys removed in 0.7.0: ... at boot or on reload: the seed file or the stored configuration value still uses the 0.6.x inherit_env/allowed_env keys (nest them under env: as inherit/allow) or the single-root fs.host_root alias (use fs.host_roots: []) — see Upgrading to 0.7.0.
`allowlist` (removed in 0.8.0, no replacement) at boot or on reload: the seed file or the stored configuration value still carries the removed allowlist key (even an empty allowlist: [] trips this) — see Upgrading to 0.8.0 for the fix.
A relative path (including ~) passed to shell::fs::*/cwd behaves unexpectedly: paths are never shell-expanded. ~ is not resolved to your home directory — when jailed, a relative path (including one starting with ~) resolves against the primary fs.host_roots entry, so ~/foo is interpreted as a path literally named ~ under that root, not your home directory; when unjailed, only absolute paths are accepted at all, so a relative path (including ~/foo) is rejected outright. Pass an absolute, already-expanded path instead.
