# To greenfield

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User says 'greenfield this' or 'rescue this codebase', or names a field. |
| Authority | Reversible local: writes only named local artifacts for exactly one bounded first corrective action (read-only diagnosis first); rollback is stated before any mutation (version control or undo). No remote mutation. |
| Side effect | Field diagnosis and the first corrective action are reported in chat; durable effects are limited to the single bounded action this skill executes under its own authority. |
| Done | The field (dark, red, brown, or blue) is named with its one-fact evidence and the first corrective action has been executed. |

## Inputs

1. **Target scope** (required): one repository region or subsystem to diagnose. "Greenfield this" scopes to the subsystem the working session covers; a larger repository is diagnosed per subsystem, never as one undifferentiated whole.
