- New Terminal tab in the workspace shell, backed by xterm.js, that connects
to the worker's PTY WebSocket using a short-lived token minted by
/api/agent-jobs/:id/terminal-token (owner-auth'd, never exposes the worker
secret to the browser)
- Site-matched xterm theme (light/dark, live theme switching), Victor Mono,
binary stdin + JSON resize protocol, reconnect, graceful 'not configured'
state when NEXT_PUBLIC_SPOON_AGENT_WORKER_WS_URL is unset
- env: NEXT_PUBLIC_SPOON_AGENT_WORKER_WS_URL (client), SPOON_AGENT_TERMINAL_SECRET
- attachTerminalServer() upgrades /jobs/:id/terminal WS connections, verifying a
short-lived job-scoped HMAC token (verifyTerminalToken) so the browser never
holds the worker secret
- Bridges the socket to a bash PTY via dockerode exec (Tty) in a persistent
per-job shell container (spoon-agent-term-<id>) mounting the workspace; binary
frames = stdin, JSON text frames = resize; idle containers reaped after 30m
- New env: SPOON_AGENT_TERMINAL_IMAGE/SECRET/IDLE_MS (secret falls back to the
shared worker internal token)
- Add spoon-dark/spoon-light Monaco themes built from the site's design tokens
(teal --primary accent), switched by next-themes resolvedTheme
- Use Victor Mono (with ligatures + italic comments) for the editor font
- Disable Monaco's in-browser TS *semantic* diagnostics, which were false
positives (no node_modules / path aliases in the browser) e.g. 'Cannot find
module ~/server/auth'; keep real syntax-error reporting
- Gate the tree/diff/status loads (and 5s poll) on workspaceStatus being
active/idle, so we no longer hammer the 'workspace is not active' endpoint
while a worker is still picking up the job
- Show a 'Setting up your workspace…' pending state instead of surfacing
startup as a console error / stale-workspace recovery box; escalate to a
softer 'still waiting' hint after 90s if no worker picks it up
- Auto-reload the diff and file tree (debounced) whenever the agent records a
workspace change or a turn starts/ends, so diffs appear without a manual
Refresh
- The recovery box now only appears for a genuinely lost workspace (Convex
reports active but the worker can't reach it)
Replace the raw single-blob diff dump (Monaco, language=diff) and the plain
<pre> file diffs in chat with @git-diff-view/react:
- Parse the unified git diff into structured per-file entries (status,
+/- counts, binary detection) via parseDiffFiles()
- Workspace Diff tab: collapsible per-file cards with status badges, line
counts, syntax highlighting, and a Unified/Split toggle
- Agent chat: render each change's diff highlighted instead of plain text
- Theme follows next-themes resolvedTheme (light/dark)
Root cause of the prod empty-response: the spoon-agent-worker image shipped
without a docker CLI binary, so it could never launch the codex job container.
On Debian trixie (the bun base) 'docker.io' + --no-install-recommends installs
the daemon package but omits the client (split into 'docker-cli'), leaving no
'docker' on PATH. execa('docker', ...) hit ENOENT, and with reject:false that
resolves with exitCode undefined -> coerced to 0 -> looked like a successful
empty run -> 'Codex completed without producing an assistant response'.
- agent-worker.Dockerfile: drop docker.io, install the official static docker
CLI client pinned to 29.5.3 (matches the host daemon) to /usr/local/bin/docker
- runtime/docker.ts: normalizeRunResult() so a spawn failure (exitCode null) is
always a non-zero exit carrying the real reason, never a silent empty success
- tests: cover the spawn-failure and normal-result paths
- Pin codex@0.142.0 + opencode-ai@1.17.9 in the job image (was @latest,
causing dev/prod drift)
- Worker now s the job image once per process so prod stops
running a stale Codex
- Surface Codex error/turn.failed events instead of swallowing them, so the
real failure reason is reported rather than 'no assistant response'
- Harden the Codex JSON parser to also handle the legacy msg-wrapped shape
- Fix the docker-in-docker workdir: bind-mount identical host:container path
and set SPOON_AGENT_HOST_WORKDIR (named volume can't be mounted by sibling
job containers)
- Add docs/compose.prod.yml as a documented reference deployment
