It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. The package performs install-time writes into local AI agent skill directories. This creates or updates agent instructions from a package lifecycle hook without explicit user invocation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-07-02T00:19:32.713Z - **Finished:** 2026-07-02T00:20:45.448Z - **Download time:** 767 ms - **Static scan time:** 357 ms - **AI review time:** 71610 ms - **Total time:** 72735 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 package performs install-time writes into local AI agent skill directories. This creates or updates agent instructions from a package lifecycle hook without explicit user invocation. - **Trigger:** npm install / postinstall - **Impact:** Local AI tools may later load package-supplied deployment instructions automatically or via skill discovery. - **Evidence paths:** package.json, bin/install-skills.mjs, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-07-02T00:20:45.448Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented lifecycle AI-agent skill installation - **Attack narrative:** On npm install, package.json invokes bin/install-skills.mjs. That script reads the bundled SKILL.md, creates common AI-agent skill directories in the user's home folder, and copies the skill into each location, causing agent-control instructions to be installed as a side effect of package installation. - **Rationale:** Although the copied skill is mostly product-aligned, installing AI-agent instructions during a package lifecycle hook is an unconsented control-surface mutation. This is concrete install-time behavior, so the package should be blocked. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **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:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for policy risk:** package.json runs postinstall: node ./bin/install-skills.mjs, bin/install-skills.mjs copies package SKILL.md into multiple agent skill folders under homedir, Targets include .agents, .cursor, .claude, .codex, and .copilot skill locations, Lifecycle install mutates AI-agent control surfaces without an explicit user command - **Evidence against:** SKILL.md content is package-aligned deployment guidance, not credential theft or reviewer manipulation, bin/sfdeploy.mjs only imports dist/index.js on CLI invocation, Network use is aligned to api.studyfetchdeploy.com and npm update checks, No install-time network exfiltration found ## Affected versions and remediation This report applies to @studyfetch/sfdeploy@0.7.1. - Review the evidence and your use of @studyfetch/sfdeploy@0.7.1 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.
