Coding agent CLI with read, bash, edit, write tools and session management
AI Security Review
scanned 2mo ago · by lpm-firewall-aiInspected source is a coding-agent CLI with no install hooks and no hidden exfiltration; scanner high-severity hits are minified vendor and example files plus expected agent shell tools. Remaining risk is incomplete AST coverage of those blobs, an unreadable Doom WASM example, and unpinned GitHub binary downloads, so this is a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
The user installs the package and later runs the CLI, loads example extensions, or uses find/grep tools that fetch helper binaries.
Impact
No install-time compromise is shown. Runtime shell use and GitHub binary download remain user-activated product behavior, with incomplete analysis of minified and binary blobs.
Mechanism
Dual-use agent runtime plus unparsed minified and WebAssembly example assets

Decision evidence
public snapshotAI called this Suspicious at 68.0% confidence as Dangerous Capability with high false-positive risk.
Evidence for warning
- Package advertises a coding-agent CLI with bash, edit, and write tools, which is dual-use by design.
- The Doom example ships minified Emscripten glue that static parsers cannot fully cover, plus a companion WebAssembly binary.
- Vendored highlight.min.js is minified Highlight.js and likewise fails complete AST coverage.
- At runtime the agent downloads the latest GitHub release assets for fd and ripgrep and executes them.
- Shared exec and shell helpers spawn child processes when the user runs the agent.
- Example extensions run PowerShell toast commands and the GitHub CLI after the user loads them.
Evidence against
- package.json has no preinstall, install, or postinstall scripts.
- Runtime dependencies are same-vendor @leanandmean packages, not a nested self-lifecycle chain.
- High-similarity hits are Highlight.js vendor code, Doom Emscripten glue, and documented sample extensions.
- Install telemetry sending was removed; the remaining flag only reads a setting or env value.
- Inspected network use is GitHub tool downloads and documented AI provider URLs, not a hidden drop host.
- dist/index.js only re-exports SDK modules and does not run install-time side effects.
