Studio

Isolated OpenCode Studios for Concept, CAD, PCB, and Firmware, plus a general Files explorer.

Package: @oguzkaganozt/opencode-studio · CLI: opencode-studio

All Studios are always on. Install wires OpenCode once with globally registered tools, one managed skill and primary agent per Studio, and isolation permissions that keep Home/Files on stock build without Studio capabilities.

Prerequisites

1. OpenCode ≥ 1.18.16 — authenticate your model providers.
2. Bun ≥ 1.3 on PATH (install channel + CLI runtime).
3. Node + npm recommended for PCB project scripts (if missing, build falls back to bundled tsci).
4. Restart OpenCode after install/repair so plugins, skills, agents, and permissions load.

Install

bun add -g @oguzkaganozt/opencode-studio
hash -r
command -v opencode-studio

# Greenfield: postinstall is soft — always repair
opencode-studio repair
opencode-studio status --workspace /path/to/your/project
# exit 0; plugins + skills + agents + permissions + engines must pass

From a git checkout (before/without registry publish):

bun install && bun run build
bun link   # or: bun add -g "$(pwd)"
opencode-studio repair

Domain engines ship in the package:

Engine	Source
tsci	bundled tscircuit CLI
uv	downloaded once into XDG cache on first CAD/status use
ESP-IDF / QEMU / esp-emu	reused from ~/.espressif when present, otherwise downloaded once into XDG cache on first Firmware build/sim

Quick start

# after repair (wires plugins/skills/agents/permissions into OpenCode)
opencode-studio up
# → attaches or spawns OpenCode API, starts Studio host

Open http://127.0.0.1:4173/studio — Agent home, Concept / CAD / PCB / Firmware / Files. One browser URL; OpenCode API is proxied (loopback child by default).

URL	What
http://127.0.0.1:4173/studio	Studio shell (native Agent panel)
http://127.0.0.1:4173/studio/studios/concept	Concept briefs and moodboards
http://127.0.0.1:4173/studio/studios/cad	CAD viewer
http://127.0.0.1:4173/studio/studios/pcb	PCB schematic, layout, BOM, and 3D viewer
http://127.0.0.1:4173/studio/studios/fw	Firmware projects, UART console, build/sim
Status (drawer footer)	Compact health modal: repair / restart agent
http://127.0.0.1:4173/ or /opencode	Optional OpenCode web UI (same-origin proxy)

Lifecycle: opencode-studio up supervises OpenCode (opencode serve on loopback if nothing is healthy; auto-restarts when this host spawned it). Attach instead with OPENCODE_URL. Disable spawn: OPENCODE_STUDIO_NO_SUPERVISE=1. Disable host: OPENCODE_STUDIO_AUTOSTART=0. Studio Home defaults to $HOME; agent directory follows the open project. PATH wrapper is removed on repair — do not rely on it.

Health: opencode-studio status (exit 1 if unwired). Prefer OPENCODE_SERVER_PASSWORD when binding non-loopback (shared with Studio Basic auth).

Web / LAN

export OPENCODE_SERVER_PASSWORD='strong-password'
export OPENCODE_STUDIO_HOSTNAME=0.0.0.0
opencode-studio up
# → http://<server-ip>:4173/studio

Env	Role
OPENCODE_STUDIO_HOSTNAME / OPENCODE_STUDIO_BIND=0.0.0.0|web	Force Studio bind (default: inherit parent 0.0.0.0, else loopback)
OPENCODE_STUDIO_PORT	Studio port (default 4173; multi-user: one port per Linux user)
OPENCODE_STUDIO_WORKSPACE	Explicit fixed Studio Home override (default $HOME; restart serve to change)
OPENCODE_SERVER_PASSWORD or OPENCODE_STUDIO_PASSWORD	Required for non-loopback — Basic on all Studio routes except /studio-api/health
OPENCODE_SERVER_USERNAME / OPENCODE_STUDIO_USERNAME	Basic user (default opencode if only server password is set)
OPENCODE_STUDIO_ALLOWED_ORIGINS	Extra origins when browser Origin ≠ Host (reverse-proxy)

Prefer SSH tunnel to loopback. If public: TLS at your reverse-proxy; enable WebSocket upgrade; app stays HTTP.

Config (global)

File	Purpose
~/.config/opencode-studio/studio.json	Optional absolute roots only (domains always on)
~/.config/opencode/opencode.json	Package-local plugins + managed Studio isolation permissions
~/.config/opencode/skills/studio-<id>/	Managed skills (studio-concept, studio-cad, studio-pcb, studio-fw)
~/.config/opencode/agents/<agent>.md	Managed primary Studio agents (concept, cad, pcb, firmware)

{ "roots": { "cad": "/absolute/path" } }

Missing studio.json is fine. Default layout under Studio Home ($HOME or OPENCODE_STUDIO_WORKSPACE):

$STUDIO_HOME/studio/
  concepts/<id>/             # Concept (concept.json, moodboards/, BRIEF.md)
  designs/<id>/              # CAD (design.json, parts/, …)
  circuits/<id>/             # PCB (src/circuit.tsx, …)
  circuits/catalog/parts/    # optional PCB catalog
  firmware/<id>/              # Firmware (project.json, main/main.c, sim/)

roots.<id> are absolute domain-root overrides: Concept points at the concepts folder, CAD at designs, PCB at circuits, and Firmware at the firmware projects folder. Keep one of opencode.json / opencode.jsonc.

image_generate is a platform tool (not a Studio). It writes to outputPath or the workspace cwd. Fallback: ChatGPT OAuth → xAI Grok Imagine quality → fal Nano Banana 2. Set FAL_KEY only if you want the last fallback.

Upgrade from project-local config: if global config is missing and the domain still has .opencode/studio.json with roots, roots are migrated on plugin load. Run opencode-studio repair once to finish.

CLI

opencode-studio status [--workspace <path>]     # health + version (exit 1 if broken)
opencode-studio repair [--workspace <path>]     # reinstall managed OpenCode state
opencode-studio remove                          # uninstall managed OpenCode state
opencode-studio upgrade [--check]               # bun add -g @latest
opencode-studio --help | -v

Shell completion installs on global bun add -g. Skip: OPENCODE_STUDIO_SKIP_POSTINSTALL=1.

Upgrade / rollback

opencode-studio upgrade
# or: bun add -g @oguzkaganozt/opencode-studio@latest
opencode-studio repair
opencode-studio status
# restart OpenCode

# Rollback
opencode-studio remove
bun add -g @oguzkaganozt/opencode-studio@<previous>
opencode-studio repair

Package exports

Export	Role
@oguzkaganozt/opencode-studio	Primary OpenCode plugin
