Unconsented modification of installed AI-agent control surfaces; installed instructions become available to those agents. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.87 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Global npm installation automatically detects AI agents and installs a large YuanFlow skill bundle into their skill directories. It removes existing same-named targets before creating symlinks or copies. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-03T20:16:38.712Z - **Finished:** 2026-08-03T20:17:13.813Z - **Download time:** 2586 ms - **Static scan time:** 2076 ms - **AI review time:** 30437 ms - **Total time:** 35101 ms ## Security analysis ### Published attack-surface review - **Summary:** Global npm installation automatically detects AI agents and installs a large YuanFlow skill bundle into their skill directories. It removes existing same-named targets before creating symlinks or copies. - **Trigger:** npm global install executes the postinstall hook. - **Impact:** Unconsented modification of installed AI-agent control surfaces; installed instructions become available to those agents. - **Evidence paths:** package.json, bin/yuanflow-skill.cjs, lib/skill-installer/agents.cjs, lib/skill-installer/installer.cjs, lib/skill-installer/repo-source.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-03T20:17:13.813Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-agent skill-directory mutation - **Attack narrative:** On a global npm install, the postinstall hook invokes the skill installer without an explicit install command. It detects configured directories for Codex, Claude Code, Cursor, and other agents, removes the package's target skill directory if present, then symlinks or copies the bundled skills into each detected agent. This is unconsented postinstall mutation of foreign AI-agent control surfaces. - **Rationale:** The automatic global postinstall materially alters third-party agent skill directories, rather than merely preparing this package. The skip flag and marker checks do not provide user consent or prevent broad cross-agent mutation. - **Files touched:** package.json, bin/yuanflow-skill.cjs, lib/skill-installer/agents.cjs, lib/skill-installer/installer.cjs, skills/yuanflow-skill ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`install --postinstall\` automatically., bin/yuanflow-skill.cjs proceeds on global install unless an opt-out env var is set., agents.cjs detects 13 third-party AI-agent installations., installer.cjs deletes/replaces agent skill directories and symlinks/copies the bundle., Postinstall defaults to global scope and installs every discovered packaged skill. - **Evidence against:** Postinstall is skipped for non-global installs., Targets are limited to detected agent markers and a named skill subdirectory., The packaged skill source is local, so this install path need not fetch a remote payload. ## Public findings ### 1.
