@runcanary/cli@0.1.7
Canary CLI — authenticate and onboard your repo to Canary from the terminal.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package performs persistent, cross-agent skill installation with default-on behavior during explicit CLI use and embeds instructions for autonomous later agent actions. There is no registry-install lifecycle trigger or confirmed covert exfiltration, so a warning rather than a block is supported.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the Canary CLI login flow or a command that invokes agent-skill setup.
Impact
This is a guarded but broad AI-agent control-surface modification. No install-time attack was confirmed.
Mechanism
The CLI writes SKILL.md under existing agent home directories; the written instructions direct future agent behavior and CLI use.
AI rationale
The package performs persistent, cross-agent skill installation with default-on behavior during explicit CLI use and embeds instructions for autonomous later agent actions. There is no registry-install lifecycle trigger or confirmed covert exfiltration, so a warning rather than a block is supported.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Package metadata exposes a CLI binary rather than an install hook.
- The login flow enables agent-skill setup by default unless the user passes a disabling option.
- The CLI writes a Canary skill into existing Claude, Agents, and Codex home-directory skill locations.
- That installed skill tells coding agents to run Canary verification on uncommitted work without being asked.
- Requests can send the stored Canary token as a bearer credential to the selected API base URL.
Evidence against
- No preinstall, install, or postinstall lifecycle hook was found in package metadata.
- The agent configuration write is reached through CLI commands, not automatically on registry installation.
