Up to 12 agents (3 VMs x 4 agents each) can run simultaneously, each working an independent GitHub issue from its own isolated user account. ## Overview The dispatch pipeline runs entirely from your local machine via SSH: 1. **Create** cx22 VMs from a pre-baked Hetzner snapshot (30-90 seconds boot) 2. **Inject** credentials at session time via tmpfs (never in git or cloud-init) 3. **Provision** a git clone per agent slot with an issue assignment 4. **Launch** Claude Code via SSH into a named tmux session 5. **Monitor** via `/dispatch-status` or `agent-status.sh --all` 6. **Collect** PR URLs and commit hashes when work is done 7. **Destroy** VMs to stop billing ## Prerequisites | Tool | Install | Purpose | |------|---------|---------| | `hcloud` | `brew install hcloud` | Hetzner Cloud CLI | | `terraform` | `brew install terraform` | Infrastructure provisioning (optional) | | `packer` | `brew install packer` | Build golden images | | `gh` | `brew install gh` | GitHub CLI | | `jq` | `brew install jq` | JSON parsing | You also need: - A [Hetzner Cloud](https://console.hetzner.cloud) account with an API token - An [Anthropic API key](https://console.anthropic.com) for agents, or an active Claude Max subscription - A GitHub fine-grained PAT with `contents:write` and `pull_requests:write` scoped to the target repo - `ssh-agent` running with `SSH_AUTH_SOCK` set Set your Hetzner token: ```bash export HCLOUD_TOKEN=your-token-here # Or use named contexts: hcloud context create my-project ``` ## Quick Start ### 1. Build the Golden Image (one-time setup) ```bash cd modules/cloud-dispatch/packer packer init agent-image.pkr.hcl HCLOUD_TOKEN=$HCLOUD_TOKEN packer build agent-image.pkr.hcl ``` Build takes 5-10 minutes. Creates a Hetzner snapshot labeled `purpose=ccgm-agent`. ### 2. (Optional) Apply Terraform Infrastructure ```bash cd modules/cloud-dispatch/terraform cp terraform.tfvars.example terraform.tfvars # Edit terraform.tfvars with your SSH public key and firewall settings terraform init terraform apply ``` This creates the named SSH key and firewall rules in Hetzner that the VM scripts expect. ### 3. Dispatch Issues In Claude Code, run: ``` /dispatch owner/repo --issues 42,43,44 ``` Or run the pipeline directly: ```bash # Create VMs bash lib/vm-create.sh 1 # Initialize session credentials bash lib/secrets-init.sh # Inject GitHub token into all agents GITHUB_TOKEN=$(gh auth token) bash lib/secrets-inject-all.sh --github-token "$GITHUB_TOKEN" # Clone repo and assign issues bash lib/workspace-setup-all.sh "https://github.com/owner/repo.git" --issues "42,43" # Launch agents bash lib/agent-launch-all.sh --max-turns 200 ``` ### 4. Monitor Progress ``` /dispatch-status ``` Or directly: ```bash bash lib/agent-status.sh --all ``` ### 5. Collect Results and Clean Up ``` /dispatch-stop ``` Or directly: ```bash bash lib/workspace-collect.sh --all bash lib/agent-stop.sh --all bash lib/secrets-cleanup.sh bash lib/vm-destroy.sh --all --force ``` ## Commands ### /dispatch Orchestrates the full pipeline: creates VMs if needed, injects credentials, provisions workspaces, and launches agents. ``` /dispatch owner/repo --issues 42,43,44 /dispatch owner/repo --issues 42,43,44 --vm-count 2 --max-turns 100 ``` Arguments extracted from the message: - `REPO` - GitHub repo in `owner/repo` format - `ISSUES` - Comma-separated issue numbers - `VM_COUNT` - Number of VMs to create (default: 3, or ceil(issues/4), whichever is smaller) - `MAX_TURNS` - Max turns per agent (default: 200) ### /dispatch-status Checks the status of all running agents and reports PR URLs, last log line, and elapsed time. ``` /dispatch-status ``` ### /dispatch-stop Stops all running agents and optionally destroys VMs. ``` /dispatch-stop /dispatch-stop --destroy # also destroys VMs after stopping ``` ### /vm-manage Low-level VM management. Accepts sub-commands: | Sub-command | Description | |-------------|-------------| | `create [N]` | Create N VMs from golden image (default: 3) | | `destroy [--all \| name]` | Destroy one or all VMs | | `status` | List all VMs with state and IP | | `health` | Run health checks on all VMs | | `ssh ` | Open SSH session into a named VM | ## Architecture ### System Overview ``` MacBook (orchestrator) | +-- /dispatch owner/repo --issues 42,43,44 | +-- vm-create.sh # Boot cx22 VMs from golden snapshot +-- secrets-init.sh # Generate session SSH keypair +-- secrets-inject-all.sh # GitHub PAT -> /run/secrets/agent-N/ on each VM +-- workspace-setup-all.sh# git clone + issue assignment per agent slot +-- agent-launch-all.sh # SSH -> tmux -> claude --dangerously-skip-permissions | +-- VM 1 (fsn1): agent-0 (issue 42), agent-1 (issue 43) +-- VM 2 (nbg1): agent-2 (issue 44), agent-3 (idle) +-- VM 3 (hel1): idle ``` VMs are spread round-robin across three Hetzner datacenters (fsn1, nbg1, hel1) for availability. ### VM Layout Each VM runs Ubuntu 22.04 LTS with 4 isolated agent user accounts: ``` / +-- home/ | +-- agent-0/ # agent user 0 | | +-- workspace/ # git clone lives here | | +-- assignment.json # issue metadata | | +-- status # AGENT_RUNNING / AGENT_STOPPED / AGENT_TIMEOUT | | +-- run.log # stdout from claude process | +-- agent-1/ ... | +-- agent-2/ ... | +-- agent-3/ ... +-- opt/ | +-- ccgm/ | +-- auto-shutdown.sh # cron: idle shutdown after 15m, forced after 8h +-- run/ | +-- secrets/ # tmpfs - credentials live here only at runtime | +-- agent-0/ | | +-- github_token | | +-- claude_auth | +-- agent-1/ ... +-- var/ +-- lib/ccgm/ # auto-shutdown state (last-active, vm-start timestamps) +-- log/ccgm-shutdown.log ``` ### Security Model - **Credentials not in git or cloud-init**: GitHub PAT and Anthropic key are injected at session time via SSH, written only to `tmpfs` at `/run/secrets/agent-N/` - **Ephemeral session keys**: `secrets-init.sh` generates a per-session ed25519 keypair, loads it into ssh-agent, and registers the public key with Hetzner. `secrets-cleanup.sh` revokes it. - **Agent isolation**: Each agent runs as a dedicated Linux user with no sudo access, `chmod 700` home directory, and `HISTFILE=/dev/null` - **Network egress allowlist**: iptables rules allow only `github.com` (TCP 443+22), `api.anthropic.com` (TCP 443), and `registry.npmjs.org` (TCP 443) - **Hetzner metadata API blocked**: The metadata endpoint (169.254.169.254) is blocked for non-root processes - **Fine-grained PAT scoping**: Scope the GitHub token to the specific repo being worked on ### Network The Terraform config creates a Hetzner firewall (`ccgm-dispatch-firewall`) that: - Allows inbound SSH (port 22) from any source - Blocks all other inbound traffic On each VM, iptables rules (set by the golden image security hardening script) control egress: - Allowlisted outbound: `github.com`, `api.anthropic.com`, `registry.npmjs.org` - Everything else blocked for non-root users ### VM Sizing | VM Type | vCPU | RAM | Price/hr | Recommended agents | |---------|------|-----|----------|--------------------| | cx22 | 2 | 4 GB | ~$0.006 | 1-2 | | cx32 | 4 | 8 GB | ~$0.011 | 4 | | ccx63 | 48 | 192 GB | ~$0.58 | 4 (memory-rich) | Price/hr figures come from the canonical `HOURLY_RATES` table in `lib/budget-track.sh` (the single source of truth for module pricing). Default is `ccx63` (set in `lib/common.sh` as `CCGM_SERVER_TYPE`). Override with: ```bash CCGM_SERVER_TYPE=cx22 bash lib/vm-create.sh 3 ``` ### Cost Reference Cost depends on VM type, session length, and whether you're using a Claude API key or Max subscription. VM costs only (Claude API/Max subscription is separate): | VM type | VMs | Hours/day | VM cost/month estimate | |---------|-----|-----------|------------------------| | cx22 | 3 | 8 | ~$4 | | cx32 | 3 | 8 | ~$8 | | ccx63 | 3 | 8 | ~$418 | VMs are billed per second on Hetzner. Destroy them when done to stop charges. The auto-shutdown cron job on each VM shuts it down after 15 minutes of inactivity or 8 hours of wall-clock time (whichever comes first). ## Script Reference ### VM Lifecycle | Script | Usage | Description | |--------|-------|-------------| | `lib/vm-create.sh` | `vm-create.sh [count] [--type TYPE]` | Boot N VMs from golden snapshot | | `lib/vm-destroy.sh` | `vm-destroy.sh --all [--force]` | Destroy VMs; prompts unless `--force` | | `lib/vm-status.sh` | `vm-status.sh` | List all ccgm-agent-* VMs with IP and state | | `lib/vm-health.sh` | `vm-health.sh --all` | SSH reachability + agent user + disk + memory | | `lib/vm-ssh.sh` | `vm-ssh.sh ` | Interactive SSH into a named VM | ### Secret Management | Script | Usage | Description | |--------|-------|-------------| | `lib/secrets-init.sh` | `secrets-init.sh` | Generate session keypair, register with Hetzner | | `lib/secrets-inject.sh` | `secrets-inject.sh --github-token TOKEN` | Inject credentials to one agent slot | | `lib/secrets-inject-all.sh` | `secrets-inject-all.sh --github-token TOKEN` | Inject to all agents on all VMs | | `lib/secrets-cleanup.sh` | `secrets-cleanup.sh` | Revoke session key from Hetzner, clear tmpfs | | `lib/secrets-rotate.sh` | `secrets-rotate.sh --github-token TOKEN` | Rotate credentials without destroying VMs | ### Workspace Management | Script | Usage | Description | |--------|-------|-------------| | `lib/workspace-setup.sh` | `workspace-setup.sh ` | Clone repo on one agent slot | | `lib/workspace-setup-all.sh` | `workspace-setup-all.sh --issues "42,43"` | Clone and assign across all VMs | | `lib/workspace-assign.sh` | `workspace-assign.sh ` | Write assignment.json to one slot | | `lib/workspace-collect.sh` | `workspace-collect.sh --all [--json]` | Pull PR URLs and git state from all agents | | `lib/workspace-cleanup.sh` | `workspace-cleanup.sh --all` | Remove workspace dirs from VMs | | `lib/ccgm-headless-install.sh` | `ccgm-headless-install.sh <ccgm-repo-path> <preset> <target-user-home>` | Non-interactive CCGM installer for a cloud agent user; runs on the VM, invoked internally by `workspace-setup.sh` | ### Agent Management | Script | Usage | Description | |--------|-------|-------------| | `lib/agent-launch.sh` | `agent-launch.sh <ip> <agent-index> [--max-turns N]` | Launch one agent via SSH + tmux | | `lib/agent-launch-all.sh` | `agent-launch-all.sh [--max-turns N] [--jitter N] [--dry-run]` | Launch all assigned agents with jitter | | `lib/agent-status.sh` | `agent-status.sh --all` | Report status, issue, last log, PR URL per agent | | `lib/agent-stop.sh` | `agent-stop.sh --all` | Kill tmux sessions and write AGENT_STOPPED | | `lib/agent-collect.sh` | `agent-collect.sh --all [--json]` | Collect agent results (status, PR, log tail) | | `lib/recovery.sh` | `recovery.sh check` \| `recovery.sh retry <ip> <agent-index>` \| `recovery.sh retry-all` | Scan agents for failures (rate-limited, crashed, timeout, error) and re-dispatch failed ones | ### Cost Reporting | Script | Usage | Description | |--------|-------|-------------| | `lib/cost-report.sh` | `cost-report.sh session [--json]` \| `cost-report.sh monthly [--json]` | Cost report for the current/last session or the current calendar month, from `/tmp/ccgm-budget*.json` | ### VM Auto-Shutdown | Script | Location | Description | |--------|----------|-------------| | `lib/auto-shutdown.sh` | Installed on VM at `/opt/ccgm/auto-shutdown.sh` | Cron-based shutdown: idle after 15m, forced after 8h | Configure via environment variables on the VM (`/etc/ccgm/env`): | Variable | Default | Description | |----------|---------|-------------| | `MAX_HOURS` | `8` | Wall-clock hours before forced shutdown | | `IDLE_MINUTES` | `15` | Minutes of no active tmux sessions before idle shutdown | ## Golden Image ### Building ```bash cd modules/cloud-dispatch/packer packer init agent-image.pkr.hcl HCLOUD_TOKEN=$HCLOUD_TOKEN packer build agent-image.pkr.hcl ``` Build takes 5-10 minutes. Creates a Hetzner snapshot with label `purpose=ccgm-agent`. The `vm-create.sh` script selects the most recently created snapshot with this label. ### Building with Custom Versions ```bash HCLOUD_TOKEN=$HCLOUD_TOKEN packer build \ -var "image_version=1.1.0" \ -var "node_version=22" \ -var "claude_code_version=1.5.0" \ packer/agent-image.pkr.hcl ``` ### When to Rebuild Rebuild the golden image when: - A new major version of Claude Code is released - Node.js LTS version changes - Security patches are needed (or allow unattended-upgrades to handle them) - Every 4-8 weeks as general maintenance ### What Is Baked In | Component | Notes | |-----------|-------| | OS | Ubuntu 22.04 LTS | | Node.js | 22 LTS (via NodeSource) | | pnpm | Latest stable | | Claude Code CLI | Pinned version in `agent-image.pkr.hcl` | | Playwright + Chromium | Pinned version | | git, tmux, jq, curl, python3 | System packages | | Agent users | `agent-0` through `agent-3` created | | `/opt/ccgm/auto-shutdown.sh` | Installed and registered in cron | | iptables egress rules | Applied via security-hardening.sh | ### Packer Files | File | Description | |------|-------------| | `packer/agent-image.pkr.hcl` | Main Packer template | | `packer/scripts/install-tools.sh` | Node.js, pnpm, Claude Code, Playwright | | `packer/scripts/setup.sh` | Agent users, `/opt/ccgm`, SSH config | | `packer/scripts/security-hardening.sh` | iptables, sshd hardening, unattended-upgrades | | `packer/scripts/validate.sh` | Post-build verification | ## Terraform Infrastructure The Terraform config in `terraform/` creates Hetzner resources that the scripts depend on: - **SSH key** (`ccgm-dispatch-key`) - a placeholder used when creating VMs. The actual session key is generated by `secrets-init.sh`. - **Firewall** (`ccgm-dispatch-firewall`) - inbound SSH only, all other inbound blocked These resources are optional if you create them manually in the Hetzner dashboard, but Terraform makes it reproducible. ```bash cd modules/cloud-dispatch/terraform cp terraform.tfvars.example terraform.tfvars # Edit terraform.tfvars terraform init && terraform apply ``` ## Jitter The `--jitter` option in `agent-launch-all.sh` (default: 90 seconds) staggers agent starts to avoid simultaneous Claude API requests hitting the rate limiter. With 4 agents and a 90s max jitter, total launch time is up to 4.5 minutes. Increase jitter if you see rate limit errors. Set to 0 to disable (not recommended with more than 2 agents). ## E2E Testing A manual end-to-end test script is provided at `tests/e2e-dispatch.sh`. It validates the full pipeline against real Hetzner infrastructure. ```bash # Preview without executing (no cost) bash tests/e2e-dispatch.sh --dry-run # Full run (~$2-3 cost, auto-cleans up) bash tests/e2e-dispatch.sh # Leave VMs running after test (for manual inspection) bash tests/e2e-dispatch.sh --skip-cleanup ``` Prerequisites: `HCLOUD_TOKEN` set, golden image built, `gh` authenticated, `ssh-agent` running. ## Troubleshooting ### "hcloud not authenticated" Set `HCLOUD_TOKEN` in your environment or run `hcloud context create`. ### "No snapshot found matching label purpose=ccgm-agent" Build the golden image first: ```bash cd packer && packer build agent-image.pkr.hcl ``` ### VM boots but health check fails SSH may not be ready yet. Wait 60 seconds and retry `/vm-manage health`. Check whether the VM console in the Hetzner dashboard shows a boot error. ### Agent exits immediately after launch Check that secrets were injected: ```bash bash lib/vm-ssh.sh VM_NAME "ls /run/secrets/agent-0/" ``` If the directory is empty, rerun `secrets-inject-all.sh`. ### "SSH_AUTH_SOCK is not set" `secrets-init.sh` requires a running `ssh-agent`. Start one: ```bash eval "$(ssh-agent -s)" ``` Then rerun `secrets-init.sh`. ### Rate limit errors across agents Increase the `--jitter` value when launching: ```bash bash lib/agent-launch-all.sh --jitter 120 ``` The default is 90 seconds. At 120 seconds, 4 agents take up to 6 minutes to start. ### "No running ccgm-agent-* VMs found" Run `vm-status.sh` to see VM states. VMs may have auto-shutdown. Create new ones with `vm-create.sh`. ### Secrets-cleanup fails to find session file If `/tmp/ccgm-session.json` was removed (e.g., VM reboot), manually delete the session key from Hetzner: ```bash hcloud ssh-key list hcloud ssh-key delete ccgm-session-TIMESTAMP ``` ## Manual Installation If you are not using the CCGM installer, copy the files manually. The `lib/` scripts install into their own `~/.claude/lib/cloud-dispatch/` subdirectory — the slash commands invoke them by that hardcoded path (`bash ~/.claude/lib/cloud-dispatch/<script>.sh`), and a flat `~/.claude/lib/` would collide with other modules' files (e.g. `common.sh`). ```bash mkdir -p ~/.claude/commands ~/.claude/rules ~/.claude/lib/cloud-dispatch cp commands/*.md ~/.claude/commands/ cp rules/cloud-dispatch.md ~/.claude/rules/cloud-dispatch.md cp lib/*.sh ~/.claude/lib/cloud-dispatch/ chmod +x ~/.claude/lib/cloud-dispatch/*.sh ``` Then: 1. Set `HCLOUD_TOKEN` in your environment 2. Build the golden image (see Quick Start) The `packer/`, `terraform/`, and `tests/` directories stay in the repo — they are build and infrastructure sources, not installed files. Run them from a checkout. ## Files ### rule #### rules/cloud-dispatch.md ``` # Cloud Dispatch Rules Rules that apply when working with cloud-dispatched agents. ## VM Agent Behavior When running as an agent on a cloud VM: - Always create a feature branch before making changes - Commit frequently (every significant change) for git-based recovery - Create a PR when work is complete - Never push directly to main - Use --max-turns to prevent runaway execution ## Dispatch Workflow When dispatching work to cloud VMs: - Verify VMs are healthy before dispatching - Use jittered starts to avoid rate limit thundering herd - Monitor agent status periodically - Collect results and clean up VMs when done - Track costs and stay within budget ## Security - Never embed secrets in cloud-init or commit them to git - Use fine-grained GitHub PATs scoped to the target repo - Session SSH keys are ephemeral - generated per session, revoked on cleanup - Agent isolation: each agent runs as a separate Linux user with no sudo access ``` ### command #### commands/dispatch.md ```` --- description: Delegate work to cloud VMs - dispatch GitHub issues to autonomous Claude Code agents running on Hetzner Cloud allowed-tools: Bash --- # /dispatch - Delegate work to cloud VMs Dispatch GitHub issues to autonomous Claude Code agents running on Hetzner Cloud VMs. ## Usage The user will provide: - Which repo to work on - Which issues to dispatch (by number) - Optionally: number of VMs, max turns, time limit ## Execution Steps Follow these steps in order. Use the Bash tool to run the shell scripts. ### Step 1: Parse Arguments Extract from the user's message: - `REPO`: GitHub repo (owner/repo format, or just repo name to resolve from ~/code/) - `ISSUES`: Comma-separated issue numbers - `VM_COUNT`: Number of VMs (default: 3, or issues / 4 rounded up, whichever is smaller) - `MAX_TURNS`: Max turns per agent (default: 200) - `MAX_HOURS`: Max hours before auto-shutdown (default: 4) ### Step 2: Validate Prerequisites ```bash # Check required tools command -v hcloud >/dev/null 2>&1 || { echo "ERROR: hcloud CLI not installed. Run: brew install hcloud"; exit 1; } command -v gh >/dev/null 2>&1 || { echo "ERROR: gh CLI not installed. Run: brew install gh"; exit 1; } # Check Hetzner auth hcloud server-type list >/dev/null 2>&1 || { echo "ERROR: hcloud not authenticated. Set HCLOUD_TOKEN env var or run: hcloud context create"; exit 1; } # Check GitHub auth gh auth status >/dev/null 2>&1 || { echo "ERROR: gh not authenticated. Run: gh auth login"; exit 1; } ``` ### Step 3: Check VM Status ```bash source ~/.claude/lib/cloud-dispatch/common.sh bash ~/.claude/lib/cloud-dispatch/vm-status.sh ``` If no VMs are running, create them: ```bash bash ~/.claude/lib/cloud-dispatch/vm-create.sh $VM_COUNT ``` If VMs exist, health-check them: ```bash bash ~/.claude/lib/cloud-dispatch/vm-health.sh --all ``` ### Step 4: Initialize Session Secrets ```bash bash ~/.claude/lib/cloud-dispatch/secrets-init.sh ``` Ask the user for their GitHub token if not already configured: "I need a GitHub fine-grained PAT with `contents:write` and `pull_requests:write` scoped to the target repo. Provide it now, or press Enter to use the token from `gh auth token`." If the user provides a token, set `GITHUB_TOKEN` to that value. Otherwise: ```bash GITHUB_TOKEN=$(gh auth token) ``` Then inject secrets to all VMs: ```bash bash ~/.claude/lib/cloud-dispatch/secrets-inject-all.sh --github-token "$GITHUB_TOKEN" ``` ### Step 5: Set Up Workspaces ```bash bash ~/.claude/lib/cloud-dispatch/workspace-setup-all.sh "https://github.com/$REPO.git" --issues "$ISSUES" ``` ### Step 6: Launch Agents ```bash bash ~/.claude/lib/cloud-dispatch/agent-launch-all.sh --max-turns $MAX_TURNS --jitter 75 ``` > **Concurrency — avoid the 429 throttle.** The org-level rate limit applies across *all* VMs at once, not per machine — every remote agent's requests bill against the same ceiling. Keep `VM_COUNT` modest and the launch `--jitter` on (it staggers VM starts so they don't burst together). If a run reports `Server is temporarily limiting requests · Rate limited`, that is the server throttle, not a usage cap — reduce `VM_COUNT` and re-dispatch the affected issues rather than relaunching the whole fleet. See `~/.claude/rules/concurrency-and-rate-limits.md`. ### Step 7: Report Print a summary of what was dispatched: - Number of agents launched - Which issues were assigned to which VM/agent - How to check status: "Run /dispatch-status to check progress" - How to stop: "Run /dispatch-stop to terminate all agents" - Estimated cost: roughly $0.006/hour per cx22 VM (3 VMs = $0.018/hour). For the default ccx63, ~$0.58/hour per VM. See the canonical rate table in `~/.claude/lib/cloud-dispatch/budget-track.sh`. ```` #### commands/dispatch-status.md ```` --- description: Check the status of dispatched agents across all cloud VMs allowed-tools: Bash --- # /dispatch-status - Check agent status Check the status of dispatched agents across all cloud VMs. ## Execution ### Step 1: Check Agent Status ```bash bash ~/.claude/lib/cloud-dispatch/agent-status.sh --all ``` ### Step 2: Collect Results Pull PR URLs and completed work from all VMs: ```bash bash ~/.claude/lib/cloud-dispatch/workspace-collect.sh --all ``` ### Step 3: Present Summary Format and present the results showing each agent's: - VM name and agent slot (e.g. ccgm-agent-1 / agent-0) - Assigned issue number - Status: running / completed / failed / idle - PR URL (if a PR was opened) - Last git commit message (if available) If all agents have completed, remind the user they can run `/dispatch-stop` to clean up. ```` #### commands/dispatch-stop.md ```` --- description: Stop all dispatched agents and optionally destroy cloud VMs allowed-tools: Bash --- # /dispatch-stop - Stop dispatched agents Stop all running agents and optionally destroy VMs. ## Execution ### Step 1: Stop Agents ```bash bash ~/.claude/lib/cloud-dispatch/agent-stop.sh --all ``` ### Step 2: Collect Results Pull any final results, PRs, or uncommitted work before cleanup: ```bash bash ~/.claude/lib/cloud-dispatch/workspace-collect.sh --all ``` ### Step 3: Ask About Cleanup Ask the user: "Agents stopped. What do you want to do with the VMs? 1. Keep running (reuse for another dispatch later - saves ~2 min boot time) 2. Destroy VMs (clean shutdown, stops billing)" If the user chooses destroy: ```bash # Revoke session SSH keys and clear secrets from tmpfs bash ~/.claude/lib/cloud-dispatch/secrets-cleanup.sh # Destroy all dispatch VMs bash ~/.claude/lib/cloud-dispatch/vm-destroy.sh --all --force ``` Confirm destruction with a final status: ```bash bash ~/.claude/lib/cloud-dispatch/vm-status.sh ``` ```` #### commands/vm-manage.md ```` --- description: Manage Hetzner Cloud VMs for agent dispatch - create, destroy, status, health checks, and SSH access allowed-tools: Bash --- # /vm-manage - Manage cloud VMs Manage Hetzner Cloud VMs for agent dispatch. ## Usage The user will specify an action: - `create [N]` - Create N VMs (default 3) - `destroy [--all | name]` - Destroy one or all VMs - `status` - List all VMs and their current state - `health` - Run health checks on all VMs - `ssh <name>` - Open an SSH session into a VM ## Execution Parse the action from the user's message and run the corresponding script: ```bash # For create: bash ~/.claude/lib/cloud-dispatch/vm-create.sh $N # For destroy (all): bash ~/.claude/lib/cloud-dispatch/vm-destroy.sh --all # For destroy (specific VM): bash ~/.claude/lib/cloud-dispatch/vm-destroy.sh $VM_NAME # For status: bash ~/.claude/lib/cloud-dispatch/vm-status.sh # For health: bash ~/.claude/lib/cloud-dispatch/vm-health.sh --all # For ssh: bash ~/.claude/lib/cloud-dispatch/vm-ssh.sh $VM_NAME ``` After running each command, display the output clearly.
