# Plan Then Execute
> **Frozen plans with human approval gates.**
Two-phase execution: plan in isolation, execute the frozen sequence.
> [!CAUTION]
> **Security first.** Tool outputs cannot alter the plan. Human approval required.
## Why This Exists
If tool outputs can alter the choice of later actions, injected instructions may redirect the agent toward malicious steps. This skill enforces:
1. **Plan phase** — Generate tool sequence before seeing untrusted data
2. **Approval gate** — Human reviews and approves
3. **Execution phase** — Run exactly that sequence

## Quick Example
```yaml
# PLAN.yml
plan:
name: "Deploy to staging"
status: approved # Frozen after approval
steps:
- id: 1
name: "Run tests"
tool_call:
tool: "terminal.run"
args: { command: "npm test" }
status: pending
```
## The Intertwingularity
Plan-then-execute is [planning](../planning/) with security guarantees.
