| description | Simultaneous Launch Button - Two-person rule for destructive commands. Use when coordinating dangerous operations between agents, requiring peer review for rm -rf, git push --force, kubectl delete, DROP TABLE, or terraform destroy. |
SLB — Simultaneous Launch Button
Core Capability: Two-person rule for running potentially destructive commands from AI coding agents. When an agent wants to run something risky, SLB requires peer review and explicit approval before execution.
Why This Exists
Coding agents can get tunnel vision, hallucinate, or misunderstand context. A second reviewer (ideally with a different model/tooling) catches mistakes before they become irreversible.
Critical: Commands run in YOUR shell environment, not on a server. The daemon is a NOTARY (verifies approvals), not an executor.
Quick Start
curl -fsSL https://raw.githubusercontent.com/Dicklesworthstone/slb/main/scripts/install.sh | bash
cd /path/to/project
slb init
slb session start --agent "GreenLake" --program "claude-code" --model "opus"
THE EXACT PROMPT — Basic Workflow
slb run "rm -rf ./build" --reason "Clean build artifacts" --session-id <id>
slb pending
slb review <request-id>
slb approve <request-id> --session-id <reviewer-id> --comment "Looks safe"
Risk Tiers
| Tier | Approvals | Auto-approve | Examples |
|---|
| CRITICAL | 2+ | Never | rm -rf /, DROP DATABASE, terraform destroy, git push --force |
| DANGEROUS | 1 | Never | rm -rf ./build, git reset --hard, kubectl delete, DROP TABLE |
| CAUTION | 0 | After 30s | rm file.txt, git branch -d, npm uninstall |
| SAFE | 0 | Immediately | rm *.log, git stash, kubectl delete pod |
Essential Commands
| Category | Command | Description |
|---|
| Session | slb session start --agent <name> | Start agent session |
| Session | slb session list | Show active sessions |
| Request | slb run "<cmd>" --reason "..." | Run dangerous command |
| Review | slb pending | List pending requests |
| Review | slb approve <id> --session-id <id> | Approve request |
| Review | slb reject <id> --reason "..." | Reject request |
| Hook | slb hook install | Install Claude Code hook |
| Pattern | slb patterns test "<cmd>" | Check command tier |
Claude Code Hook
slb hook install
Execution Verification (5 Gates)
| Gate | Check |
|---|
| 1. Status | Request must be APPROVED |
| 2. Expiry | Approval TTL must not have elapsed |
| 3. Hash | SHA-256 hash must match (tamper detection) |
| 4. Tier | Risk tier must still match |
| 5. First-Executor | Atomic claim prevents race conditions |
Emergency Override
For true emergencies, humans can bypass with extensive logging:
slb emergency-execute "rm -rf /tmp/broken" --reason "System emergency"
