# Secure npm package

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User wants to create, publish, or harden an npm package release using Trusted or Staged Publishing. |
| Authority | Reversible local: writes only named workflow drafts, project config files, and the handoff document; rollback is version control. No remote mutation, credential removal, tag creation, or publish. |
| Side effect | Writes hardened `publish.yaml` and `check-workflows.yaml` drafts, configures cooldown and postinstall-disablement in project config files, and lists every manual setting change in a human handoff. |
| Done | Both workflow drafts exist, cooldown and postinstall settings are written and read back, the handoff lists every human action with exact values, and no remote state changed. |

## Inputs

- Root `package.json` (required): read first to determine monorepo shape, package manager, build script, and repository URL.
