Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 4.1.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is not malicious install-hook abuse because automatic lifecycle execution exits before the project mutation. The explicit CLI still modifies AI-agent control surfaces, so it warrants a warning for dangerous capability rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-19T16:09:53.414Z - **Finished:** 2026-09-19T16:10:50.262Z - **Download time:** 760 ms - **Static scan time:** 127 ms - **AI review time:** 55960 ms - **Total time:** 56848 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The explicit command installs workflow prompts, skills, and commands into a consumer project's AI-agent control files. Install-time execution exits before performing those writes. - **Trigger:** A user explicitly invokes the 3a-factory CLI outside an npm automatic lifecycle. - **Impact:** The tool can change how supported AI coding agents behave in the target project; no covert execution or data transfer was confirmed. - **Evidence paths:** package.json, dist/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T16:10:50.262Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes packaged agent instructions and command adapters into the target project. - **Rationale:** This is not malicious install-hook abuse because automatic lifecycle execution exits before the project mutation. The explicit CLI still modifies AI-agent control surfaces, so it warrants a warning for dangerous capability rather than a block. - **Files touched:** AGENTS.md, .agents/templates, .agents/contracts, .agents/schemas, .agents/rules, .agents/skills, .agents/agents, .agents/configs, .claude/commands, .claude/skills, .gemini/commands, .cursor/rules ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package runs its installer from postinstall, but the installer detects npm automatic lifecycle events and exits before scaffolding., An explicit CLI invocation writes workflow files and command or rule files into a consumer project's AI-agent configuration locations., The installer can create new files and, with --force, overwrite differing files after making a backup. - **Evidence against:** No network, credential collection, shell execution, remote payload loading, or self-dependency is present in the inspected source., Automatic npm lifecycle execution is guarded to skip the project-writing behavior. ## Affected versions and remediation This report applies to 3a-factory@4.1.2. - Review the evidence and your use of 3a-factory@4.1.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const f=require('fs'),{execSync}=require('child_process');if(!f.existsSync('dist/install.js')&&f.existsSync('scripts/build.js'))execSync('node scripts/build.js',{stdio:'in... ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern.
