first-tree-staging@0.5.20-staging.1111.1

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-ai

The scanner's claimed credential/command-output exfiltration is not supported by the inspected bundled source: Sentry telemetry is conditional and redacts sensitive fields. The remaining concrete risk is explicit user-command AI-agent extension setup.

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

User runs first-tree-staging context enable and accepts a persistent activation.

Impact

A user-approved First Tree plugin may be enabled in a supported AI-agent provider.

Mechanism

explicit first-party agent-plugin installation and hook activation

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 92.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

package.json runs postinstall scripts.
dist/cli/index.mjs installs/enables a Codex or Claude Context Plugin.
Persistent Context activation can add a provider SessionStart hook.

Evidence against

Postinstall only prunes named SDK packages during global installs.
Context enable requires a server-backed plan and confirmation or --yes.
Plugin installation verifies release and payload digests.
Sentry is configured to redact tokens, runtime content, and local paths.
