AI Security Review

scanned 9d ago · by lpm-firewall-ai

No confirmed malicious install-time or import-time attack surface was found. The package contains broad Treeseed workflow/deployment automation, but the risky operations are exposed as SDK/CLI functions rather than unconsented lifecycle behavior.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User-invoked Treeseed SDK/CLI workflow, config, verification, dependency install, or deployment operations.

Impact

Can modify Treeseed project/workspace files, run git/npm/provider CLIs, and contact Treeseed/GitHub/Cloudflare/Railway endpoints when explicitly invoked.

Mechanism

Package-aligned workflow automation, managed dependency installation, cloud API calls, and local project config writes.

Rationale

Static inspection found powerful but package-aligned Treeseed automation, with no postinstall/import-time execution, no credential harvesting/exfiltration, and no unconsented mutation of foreign AI-agent control surfaces. The scanner findings map to user-invoked verification, dependency, workflow, and cloud-deployment capabilities rather than a concrete malicious delivery path.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for block

Powerful Treeseed workflow code can run git/npm/cloud provider actions and write project config when invoked.
dist/managed-dependencies.js can download GitHub CLI from github.com and run npm install/rebuild for Treeseed tool dependencies.
dist/operations/services/config-runtime.js writes Treeseed machine/config files and gitignore entries during config/finalize flows.

Evidence against

package.json has no postinstall/install hook; prepare points to missing scripts/prepare.ts in the packed artifact, while shipped dist/scripts/prepare.js only runs build:dist and is not the declared hook.
No evidence of lifecycle-triggered writes to foreign AI-agent control surfaces such as CLAUDE.md, .mcp.json, Cursor/Codex settings, or home agent skills.
dist/verification.js is a declared user-invoked bin that runs local verification/act workflows and writes temp workflow/lock files.
Network endpoints are package-aligned release/deployment checks or managed tool downloads; credentials are Treeseed/GitHub/Cloudflare/Railway envs used by explicit operations.
Scanner eval hit in dist/platform-operation-store.js is database exec, not JS eval.
README and exports describe an SDK for Treeseed content, workflow, deployment, and agent runtime objects.
