Pass `--no-sandbox` to disable it and accept the warning. `odek run` keeps sandbox opt-in (Docker isn't installed everywhere), but emits a startup warning when running unsandboxed. +**The sandbox is on by default for CLI runs.** `odek run`, `odek continue`, and `odek repl` sandbox every session unless something opts out: `--no-sandbox` / `ODEK_NO_SANDBOX=1`, or an explicit `"sandbox": false` in trusted config. When the sandbox is wanted only by *default* (nobody asked for it explicitly) and Docker is unavailable — or a project `Dockerfile.odek`/sandbox knobs lack approval — the run degrades to unsandboxed with a loud notice instead of failing, since breaking every Docker-less user is not containment either. That fallback is reversible policy, not fate: `ODEK_REQUIRE_SANDBOX=1` makes any unsandboxed fallback fatal, and an explicit `--sandbox` always hard-fails as before. `odek continue` pins the session's original sandbox posture rather than inheriting the new default, so containment never flips mid-conversation. The rationale is simple: the sandbox is the one control that actually contains the "agent ran attacker-controlled code" class — the failure mode where model quality does not help — so isolation is what you get unless you deliberately give it up. `odek serve` keeps its own default-on behavior. **Implicit `Dockerfile.odek` builds are approval-gated.** A `Dockerfile.odek` in the working directory is repo-controlled, and `docker build` executes its `RUN` instructions outside the sandbox threat model (default capabilities, entire working directory readable as build context). The implicit build is therefore gated like project sandbox overrides: an interactive TTY prompt at startup (`y` = once, `t` = trust this project), persisted approvals in `~/.odek/project_sandbox_approvals.json`, or `ODEK_APPROVE_PROJECT_SANDBOX=1` for CI. Non-TTY runs without approval fail closed. The approval key includes the **Dockerfile content hash**, so editing the file invalidates a prior trust and forces re-review, and `setupSandbox` re-verifies approval immediately before building — closing the window where a Dockerfile appears or changes after startup (e.g. a serve-mode sandbox created per WebSocket connection). Builds run with `--network=none` by default, so `RUN` steps cannot fetch payloads or exfiltrate build-context data; `ODEK_SANDBOX_BUILD_NETWORK=1` (operator-only) opts back into networked builds for legitimate package installs. @@ -110,7 +110,7 @@ If the sidecar flags content, the behavior mirrors a local scan flag: writes are ### Danger classifier -The `shell` tool tokenises commands and classifies each into one of 9 risk classes (`safe`, `local_write`, `system_write`, `destructive`, `network_egress`, `code_execution`, `install`, `unknown`, `blocked`).

Covered targets: shell profiles (`.bashrc`, `.zshrc`, `.profile`, `.zprofile`, fish `config.fish`, …), direnv `.envrc`, `.git/hooks/*`, CI workflow files (`.github/workflows/`, `.gitlab-ci.yml`, …), cron (`crontab` installation, `/etc/cron.*`), systemd system and user units, macOS LaunchAgents/LaunchDaemons, `/etc/profile.d`, `npm pkg set`/`npm set-script` lifecycle hooks, and `jq '.scripts…'` rewrites of `package.json`. Write tools additionally sniff content: a `package.json` edit that plants an install lifecycle script (`preinstall`, `postinstall`, `prepare`, …) or a `conftest.py` edit that plants an `autouse=True` fixture escalates even though the file itself is ordinary. The class ranks above `system_write`, prompts by default, is denied under non-interactive `deny`, and — like `destructive` — is never eligible for the session-trust shortcut: its writes execute *outside* the session that granted the trust.

A **failed** read never licenses execution — the observed failure mode of a capable model whose `cat` errored on a path typo and fell back to running the file stays gated. The gate intercepts approval even when `code_execution` was set to `allow` or its class trusted (the entire point is per-script review), is never session-trust-shortcuttable, and honors an explicit `"unread_exec": "allow"` override for operators who want exactly that. + ### Tool-call approval When a classification is set to `prompt`, an approver pauses the agent until the user decides. Three implementations share the same policy helpers: the **TTYApprover** (CLI / REPL, reads from `/dev/tty`), the **WSApprover** (Web UI — sends `approval_request` over WebSocket and relays responses through a non-blocking send on a capacity-1 channel, so a duplicate, late, or raced response cannot block the read goroutine), and the **TelegramApprover** (inline keyboards). -- **Trust shortcuts are withheld for dangerous classes.** The "trust class for session" shortcut is hidden for `destructive`, `blocked`, `unknown`, and the synthetic `tool_batch` class. The exclusion lives in one shared place, `danger.TrustShortcutAllowed` — used by the TTY and Web approvers and mirrored in the Telegram approver — and a forged or stale "trust" response for those classes is refused: the Web approver coerces it to a single approve of the pending call, the Telegram approver denies it, and the TTY approver re-prompts with a notice. One Trust click on a batch card can never auto-pass every per-tool prompt for the session. +- **Trust shortcuts are withheld for dangerous classes.** The "trust class for session" shortcut is hidden for `destructive`, `blocked`, `unknown`, `persistence`, `unread_exec`, and the synthetic `tool_batch` class.

One Trust click on a batch card can never auto-pass every per-tool prompt for the session. - **Friction mode** engages after 3 approvals of the same class in 60 s: the next prompt requires typing the literal word `approve` (no single-letter / button shortcut) and imposes a 1.5 s pause before accepting input. This breaks reflex click-through under sustained LLM-driven approval pressure. - TTY prompts are serialized process-wide (one mutex, one shared approval log), so concurrent tool calls cannot print overlapping prompts, and the friction counter and trust cache persist across prompts and across `shell`/`parallel_shell` tool instances. -- **Non-interactive defaults to deny.** When no TTY is available (headless/CI/piped input), prompted operations fall back to the `non_interactive` action, whose built-in default is `"deny"`. Only `"allow"` and `"deny"` are accepted; any other value is coerced to deny at load time with a warning, because a non-interactive environment cannot prompt. Unattended runs must explicitly opt in to auto-approval via `~/.odek/config.json` or the CLI. Sub-agents and other TTY-less contexts default the same way (configurable). +- **Non-interactive defaults to read-only.** When no TTY is available (headless/CI/piped input), prompted operations fall back to the `non_interactive` action, whose built-in default is `"read_only"`: read-only inspection proceeds — `safe`-classified shell commands (`ls`, `cat`, `tree`) and native read tools over ordinary paths — while writes, execution, egress, and reads of sensitive locations (anything at `system_write` or above) are denied. `"deny"` (block everything prompted, including reads) and `"allow"` remain available; an explicitly configured *invalid* value fails closed to `"deny"` with a load-time warning. The read_only default exists because containment via inability is not safe-and-useful: a headless agent that cannot even `ls` gets its operator to flip `non_interactive` to `allow`, which removes every protection — `read_only` is the setting that survives contact with a deadline. **Batch approval card.** `classifyToolCall` (in the loop) classifies every command inside `parallel_shell`, every path inside `batch_patch`, and the `browser` tool (action + URL → `network_egress`); MCP tools (detected by the `__` naming convention) classify as `unknown`. The card shows full command/path text instead of truncating, and blanket `SetTrustAll` is refused for any iteration that still contains an unclassifiable tool — those must pass their own internal gates. Session-trusted risk classes are honored uniformly across `write_file`, `patch`, and `batch_patch`. +### Reply/ledger reconciliation + +Detection that lands *after* a side effect is reporting, not prevention — but a final reply that **misreports** the side effect is worse than silence, because a confident all-clear actively stops the user from looking.

Before a final answer is returned, the loop diffs its claims against a run-scoped ledger of completed mutating tool calls (`write_file`/`patch`/`batch_patch` successes; `shell`/`parallel_shell` commands classified `local_write` or higher; failed calls excluded). When a reply denies actions the ledger shows completed ("I did not run…", "no changes were made", "the setup is blocked"), odek appends a clearly-attributed consistency notice — the runtime speaking, not the model — naming up to five of the actions, and emits a `reply_ledger_mismatch` signal.

Non-TTY runs without approval fail closed. The approval key includes the **Dockerfile content hash**, so editing the file invalidates a prior trust and forces re-review, and `setupSandbox` re-verifies approval immediately before building — closing the window where a Dockerfile appears or changes after startup (e.g. a serve-mode sandbox created per WebSocket connection).
