Personal AI agent toolkit installer for Claude Code, Codex CLI, OpenCode, Gemini CLI, Antigravity and graph-aware workflows.

AI Security Review

scanned 5d ago · by lpm-firewall-ai

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

Static reason

No blocking static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs agent-toolkit/setup-agent-toolkit CLI with selected install flags or interactive confirmation.

Impact

Can modify local/global AI agent skill/plugin surfaces and install external tools, but not during npm install and not stealthily based on inspected source.

Mechanism

CLI-driven installation of plugins, skills, external tools, and runtime CLIs with pinned provenance checks.

Rationale

This is not malicious by source inspection: risky primitives are aligned with the advertised installer and are activated by explicit CLI use, with no npm install-time foreign agent control mutation. Because it intentionally mutates AI-agent extension surfaces and installs external capabilities, a warning is appropriate rather than a publish block.

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

dist/src/skills.js copies bundled skills into ~/.claude, ~/.codex, opencode, ~/.gemini, Antigravity, or local project skill dirs when CLI is run.
dist/src/installers/superpowers.js invokes claude/codex/gemini plugin or extension install commands.
dist/src/installers/rtk.js downloads a GitHub release asset, verifies SHA-256, installs an rtk binary, then runs rtk init --global --auto-patch.
dist/src/runtimes.js can pipe the official Antigravity installer URL to bash, but only under --install-missing-clis/user-selected runtime flow.

Evidence against

package.json has no preinstall/install/postinstall hook; npm install does not run the agent config mutation path.
bin entrypoint only calls runInstaller; setup-agent-toolkit.sh is a wrapper around node dist/bin/agent-toolkit.js.
External tool sources are pinned in tools.lock.json and provenance checks reject mutable or identity-changing overrides unless explicitly allowed.
No credential harvesting, secret exfiltration, destructive filesystem sweep, obfuscation, eval/vm, or import-time execution found in inspected source.
