first-tree-staging@0.5.19-staging.1093.1
First Tree — unified CLI for Context Tree onboarding, agent management, and team messaging. (Source-tree dev build; CI rewrites `name` and `bin` for prod / staging publishes — see docs/local-dev-isolation.md.)
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has an install-time destructive primitive and default telemetry, warranting a warning, but inspection does not substantiate the scanner's credential or command-output exfiltration claim. There is no unconsented foreign AI-agent control-surface mutation or payload execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm install -g first-tree-staging; telemetry activates when the CLI initializes.
Impact
May remove runtime dependencies installed for this CLI's global tree; no confirmed credential or command-output exfiltration.
Mechanism
global dependency pruning and sanitized error telemetry
AI rationale
The package has an install-time destructive primitive and default telemetry, warranting a warning, but inspection does not substantiate the scanner's credential or command-output exfiltration claim. There is no unconsented foreign AI-agent control-surface mutation or payload execution.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs three postinstall pruning scripts.
- Pruning scripts recursively delete resolved Claude/Codex SDK platform packages and two SDK peers during global installs.
- dist/connect-token-68vMhBZC.mjs embeds a Sentry ingestion DSN enabled by default.
Evidence against
- Postinstall guards require npm_config_global=true and skip source-monorepo installs.
- Pruning targets declared SDK dependencies and has opt-out environment flags.
- Sentry setup disables default PII, breadcrumbs, and sanitizes sensitive keys/runtime content.
- Credential refresh and API calls use the configured First Tree server URL, not a hidden receiver.
- No source evidence of secret harvesting, command-output upload, remote payload execution, or foreign agent-config mutation.
