A reproducible, self-documenting, and recoverable OpenCode development workstation — configuration, agent skills, MCP stack, and an MCP server that clones the entire setup onto any Linux machine (locally or over SSH).
Homepage & remote MCP: https://opencode-workbench.simonmak.com · POST https://opencode-workbench.simonmak.com/mcp
This repository is the single source of truth for a complete cloud development workstation. Everything needed to rebuild from scratch is versioned here:
- Workstation configuration and automation
- OpenCode configuration (model, providers, MCP servers)
- Agent skills (45 reusable AI instructions across research, dev, data, science and ops)
- Operational prompts (disaster recovery, backup, security)
- Recovery procedures (playbook, checklist, gap analysis)
- Security governance (secret management, threat model)
- OpenCode sandbox (bubblewrap) — run the agent with a read-only system and no secret mounts
opencode-workbench— an MCP server that installs this profile on any Linux box
No important knowledge exists only in human memory.
Register the MCP server with OpenCode:
{
"mcp": {
"opencode-workbench": {
"type": "local",
"command": ["npx", "-y", "@simonmak-ascent/opencode-workbench"],
"enabled": true,
"timeout": 600000
}
}
}Then ask the agent to run inspect_target → plan_clone → apply_clone { confirm: true } → verify_clone, for { "mode": "local" } or { "mode": "ssh", "host": "<your-box>", "user": "<your-user>" }. apply_clone is consent-gated: without confirm:true it returns a plan (components + privileged-command preview) and changes nothing. Run list_required_credentials to see which keys the box still needs and how to acquire them, and bash scripts/selftest/run-selftest.sh to verify it works. See mcp-server/README.md and docs/architecture/clone-mcp.md.
The clone is key-resilient: with no model key it still boots on the OpenCode Zen free floor, and MCP servers whose credentials are absent are disabled and reported (not left to fail at runtime).
The connector never reads or transmits secret values; it writes an empty ~/.env.workbench template for you to fill in.

| Prompts | 9 operational prompts in docs/prompts/ |
This workstation operates under a formal charter. Key principles:
- Single Source of Truth: Runtime must match repository. Drift is a bug.
- Secrets Never Touch Disk: All secrets flow through the build box Secrets.
- Immutable History: Changelog is append-only. Every change is traceable.
- Documentation Lives With Code: Docs describe the system as it is, not as imagined.
Read the full charter: docs/WORKBENCH_CHARTER.md
# Master backup — full inventory, security scan, commit prep
bash scripts/backup/run-master-backup.sh
# Quick backup — save state before risky operations
bash scripts/maintenance/sync-runtime-config.sh && \
git diff > /tmp/quick-backup-$(date +%Y%m%d).diffOr use OpenCode prompts:
docs/prompts/RUN_MASTER_BACKUP.md— execute backup via AIdocs/prompts/QUICK_BACKUP.md— rapid state preservation
Assume the build box is deleted. Only Git repo + build box Secrets survive.
# 1. Create new build box
gh SWAS create --repo simonmak-ascent/opencode-workbench --machine basicLinux32gb
# 2. Wait for automation (3-5 min)
# 3. If needed (usually done by setup.sh):
npx playwright install chromium
# Vercel MCP uses VERCEL_ACCESS_TOKEN (token auth — no OAuth step)
# 4. Validate recovery
bash scripts/recovery/validate-recovery.shFull details: docs/recovery/RECOVERY_PLAYBOOK.md
| Type | Count | Notes |
|---|---|---|
| Remote | 9 | context7, gh_grep, vdd, exa, cloudflare, clerk, vercel (token auth), sentry, stripe |
| Local | 26 | npm / vendored / binary stdio servers |
Totals: 35 configured (33 enabled, 2 disabled: google-search, google-workspace).

- MCP Server: Add npm package to
.devcontainer/setup.sh, add toopencode.json, document indocs/architecture/mcp-inventory.md - Agent Skill: Create
.opencode/skills/<name>/SKILL.md, follow naming convention - Tool: Add to
scripts/bootstrap-tools.sh - Prompt: Create in
docs/prompts/, updateprompt-index.md - After any change: Update
CHANGELOG_WORKBENCH.md, run master backup
Validated disaster recovery within < 10 minutes using repository + build box Secrets alone.
