syCode — the terminal agent with a central nervous system

syCode is a premium terminal coding agent: Skill Sets, MCP Integration, Dynamic Cloud Configuration, and Universal Context Sync, managed through sycode-cloud. Interfaces, not plumbing: log in once on any surface and your account, tier, models, devices, and sessions are all handled for you. Full documentation at code.synotech.dev/docs.

Install

curl -fsSL https://code.synotech.dev/install.sh | sh
sycode signup           # email + password, verified (or: sycode login)

Requires Node.js 22+ (the installer verifies and tells you exactly what to run if it's missing).

Use

sycode                        # interactive terminal agent
sycode -p "explain this repo" # headless single-shot
sycode --help                 # all options

One login initializes everything: your device is registered, your tier and model catalog are fetched, and your first session is created — ready to type. Sessions are automated: every turn syncs to the cloud so you can resume from any logged-in machine. No keys to copy, no sessions to sync, nothing to configure. (A web console for browsing sessions, managing devices, and remote drive is planned; today that surface is the TUI plus sycode logout [--purge].)

Agent modes: build has full tool access, plan is read-only analysis, goal is objective-driven delivery tracked against a durable goal. Switch with /mode [name], cycle with Shift+Tab, start in one with sycode --agent-mode plan. The current mode shows in the footer.

Autonomous mode: sycode --yolo (or /yolo on) auto-allows permission asks — deny rules still stand and every auto-approval is logged. Revert anytime with /yolo off or sycode --no-yolo.

Browser automation

syCode can drive your real, logged-in Chrome/Edge browser — for testing UIs, scraping data behind auth, filling forms, taking screenshots, or operating any site you're already signed into.

How it works:

• The sycode-browser CLI daemon is bundled with syCode and auto-installed on npm install (downloads the correct platform binary from GitHub Releases).
• The Chrome extension is a separate one-time install from the Chrome Web Store.
• Once both are in place, syCode registers 12 browser tools automatically.

Install the extension:

1. Go to Chrome Web Store → search "syCode Browser"
2. Click the extension icon → confirm it shows "Connected"
3. Ask syCode: "Open github.com and tell me what's on the page"

Security: ask-by-default at the permission gate. The agent never sees your cookies directly — it asks the local daemon to perform actions in a separate Agent Window. Tab borrowing requires your explicit approval in the extension popup.

See sycode-browser README for full details.

Team daemon

One process per team host for remote monitoring — and you never start it by hand: the first interactive run attaches or starts it (token minted, jail derived, loopback-bound). Bearer auth, audit log, quotas, live session streaming. Manual operation and servers still use env:

sycode-daemon   # needs SYCODE_DAEMON_TOKEN + SYCODE_WORKSPACES in the environment
sycode daemon status | stop   # escape hatch (ambient otherwise)

| Method | Route | Notes | |---|---|---| | GET | /health | public liveness | | GET | /daemon/status | sessions, quotas, workspace roots | | POST | /sessions {cwd} | cwd must be inside SYCODE_WORKSPACES | | GET | /sessions/:id/events | SSE stream (replay last 200 + live) | | POST | /sessions/:id/prompt {message} | rate-limited per token | | POST | /sessions/:id/steer /follow_up {message} | queue steering (rate-limited) | | POST | /sessions/:id/abort | abort current run | | POST | /sessions/:id/clear_queue | drop queued prompts | | POST | /sessions/:id/compact {customInstructions?} | compact now | | POST | /sessions/:id/fork {entryId} /clone | branch session | | POST | /sessions/:id/switch {sessionPath} | switch backing session | | POST | /sessions/:id/name {name} | rename session | | GET | /sessions/:id/messages ?since= | entries | | GET | /sessions/:id/tree /stats | branch tree / usage stats | | GET/DELETE | /sessions/:id | state / close child |

Security notes: tokens live on the daemon host only (env), never in logs or audit rows (fingerprint prefix only). Extension dialogs auto-cancel (non-interactive remote runs must never hang on a TTY prompt).

Interfaces & accounts

• TUI — the primary interface, works fully offline on cached models.
• Login page — email + password auth with CLI loopback handoff.
• Web console — planned: sign in, browse/resume sessions, manage devices and entitlements, drive a remote session.
• Accounts — email + password (GitHub/Google one-click lands later). Sessions are server-issued and tied to your account; sycode logout revokes this device, logout --purge also deletes your cloud data.
