HOL Guard Skill Guidance

Use this guidance when an AI agent is about to add or update dependencies.

Before package installs

Preview the install decision:
- hol-guard protect --dry-run -- npm install <package>
Check current workspace risk posture:
- hol-guard supply-chain scan --json
Explain a specific package verdict:
- hol-guard supply-chain explain <package>@<version> --ecosystem <ecosystem>
Confirm package manager interception is installed:
- hol-guard package-shims status --json
Repair a missing or tampered package manager shim:
- hol-guard package-shims repair --manager npm --json

Cursor editor and Cursor CLI

Cursor has two protection surfaces. Cursor editor covers MCP servers in .cursor/mcp.json. Cursor CLI covers the cursor-agent command path. Keep them distinct when activating, checking, repairing, or removing Guard.

Connect Cursor editor protection:
- hol-guard apps connect cursor --surface editor
Connect Cursor CLI protection:
- hol-guard apps connect cursor --surface cli
Test a Cursor surface without changing config:
- hol-guard apps test cursor --surface editor
- hol-guard apps test cursor --surface cli
Repair only the stale surface named by Guard Cloud:
- hol-guard apps repair cursor --surface editor
- hol-guard apps repair cursor --surface cli
Remove protection only after confirmation:
- hol-guard apps disconnect cursor --surface editor --confirm disconnect-cursor
- hol-guard apps disconnect cursor --surface cli --confirm disconnect-cursor

Guard owns trust checks, drift repair, redacted receipts, and Cloud sync. Cursor owns its native editor and CLI behavior. If a surface is missing, unsupported, or unavailable, report that state instead of inventing an install URL or fallback command.

During CI and automation

Route dependency installs through Guard:
- hol-guard protect -- npm ci
Use workspace audits before release:
- hol-guard supply-chain audit --json

If Guard blocks a package

Review the blocking reason and suggested fix version.
Prefer upgrading to a safe version.
If it is a verified false positive, use a scoped and expiring exception with recorded reason.
