The package can alter future agent behavior without an explicit setup command and steer agents toward package-controlled deployment and update actions. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.11.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. An npm postinstall writes a package-controlled agent skill into multiple unrelated user-wide agent control surfaces. The installed skill broadly intercepts deployment requests and instructs agents to keep this package updated. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-06T03:49:33.769Z - **Finished:** 2026-09-06T03:50:36.437Z - **Download time:** 765 ms - **Static scan time:** 740 ms - **AI review time:** 61163 ms - **Total time:** 62668 ms The recorded confidence comes from the underlying analysis.

The installed skill broadly intercepts deployment requests and instructs agents to keep this package updated. - **Trigger:** Installing the package through npm with lifecycle scripts enabled. - **Impact:** The package can alter future agent behavior without an explicit setup command and steer agents toward package-controlled deployment and update actions. - **Evidence paths:** package.json, bin/install-skills.mjs, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-06T03:50:36.437Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-platform AI-agent skill installation and update instruction injection. - **Attack narrative:** During npm installation, the postinstall script creates directories and copies its skill into shared and vendor-specific AI-agent skill locations. That skill is designed to activate on generic deployment requests, route work through this package, and instruct agents to update or reinstall it. This is an unconsented mutation of broad, foreign agent control surfaces. - **Rationale:** This is concrete automatic install-time modification of multiple user-wide AI-agent control surfaces, not an explicit user-command setup. The injected instructions create a continuing path to package-directed updates and deployment behavior. - **Files touched:** SKILL.md, ~/.agents/skills/sfdeploy/SKILL.md, ~/.cursor/skills/sfdeploy/SKILL.md, ~/.cursor/skills-cursor/sfdeploy/SKILL.md, ~/.claude/skills/sfdeploy/SKILL.md, ~/.codex/skills/sfdeploy/SKILL.md, ~/.copilot/skills/sfdeploy/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs an installer automatically after npm installation., The installer creates and overwrites skill files across six user-wide AI-agent directories., The injected skill activates for broad hosting and deployment requests and directs agents to this CLI., The skill directs agents to update or globally reinstall the package before deploying. - **Evidence against:** The postinstall installer itself does not send files or environment values over the network., The ordinary API client appears tied to explicit CLI operations rather than the install hook. ## Affected versions and remediation This report applies to @studyfetch/sfdeploy@0.11.0. - Avoid installing @studyfetch/sfdeploy@0.11.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
