OpenCode Workbench
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).

Overview
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 (76 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.
Clone This Workbench to Another Linux Machine
Register the MCP server with OpenCode:
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.
Quick Start (≤ 5 minutes)
Fastest path: no box required — register the MCP server with
npx -y @simonmak-ascent/opencode-workbench (config in
Clone This Workbench); or provision a fresh box:

What's Inside
Workstation Governance
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
Backup Workflow
Or use OpenCode prompts:
docs/prompts/RUN_MASTER_BACKUP.md — execute backup via AI
docs/prompts/QUICK_BACKUP.md — rapid state preservation
Recovery Workflow
Assume the build box is deleted. Only Git repo + build box Secrets survive.
Full details: docs/recovery/RECOVERY_PLAYBOOK.md
MCP Architecture
Totals: 31 configured (29 enabled, 2 disabled: google-search, google-workspace).
See: docs/architecture/mcp-inventory.md
Secrets Management
All secrets stored in the build box Secrets. Never in repository files.
Additional keys for opt-in servers (EXA_API_KEY, CLOUDFLARE_API_TOKEN,
STRIPE_SECRET_KEY, SURREAL_*, ALIBABA_CLOUD_*, AZURE_*, FIRECRAWL_API_KEY,
FRED_API_KEY, COMPANIES_HOUSE_API_KEY) are catalogued in
docs/architecture/secrets.md — never by value.
See: docs/architecture/secrets.md
Documentation Index
Adding to the Workbench
- MCP Server: Add npm package to
.devcontainer/setup.sh, add to opencode.json, document in docs/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/, update prompt-index.md
- After any change: Update
CHANGELOG_WORKBENCH.md, run master backup
Recovery Score: 94/100
Validated disaster recovery within < 10 minutes using repository + build box Secrets alone.
