A package installation can alter available instructions and capabilities of unrelated AI coding 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:** 0.8.5 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation automatically adds an Uncloud instruction skill to already-present third-party coding-agent directories. This changes agent behavior without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-15T23:21:30.665Z - **Finished:** 2026-08-15T23:23:01.871Z - **Download time:** 506 ms - **Static scan time:** 137 ms - **AI review time:** 90562 ms - **Total time:** 91206 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically adds an Uncloud instruction skill to already-present third-party coding-agent directories. This changes agent behavior without an explicit setup command. - **Trigger:** npm install executes postinstall unless UNCLOUD\_SKIP\_SKILL=1 or CI=true. - **Impact:** A package installation can alter available instructions and capabilities of unrelated AI coding agents. - **Evidence paths:** package.json, bin/postinstall.js, lib/skill.js, skills/uncloud/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-15T23:23:01.871Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes a bundled SKILL.md into Claude Code, Codex, and opencode skill paths. - **Attack narrative:** On npm installation, postinstall calls install(). If a supported agent directory already exists, the package creates that agent's uncloud skill directory and writes its bundled instructions there. This is an unconsented install-time mutation of third-party AI-agent control surfaces, even though it has opt-outs and avoids replacing customized files. - **Rationale:** The package performs automatic postinstall writes into Claude Code, Codex, and opencode skill paths. This meets the firewall block boundary for unconsented install-time mutation of foreign AI-agent control surfaces. - **Files touched:** bin/postinstall.js, lib/skill.js, skills/uncloud/SKILL.md, ~/.claude/skills/uncloud/SKILL.md, ~/.agents/skills/uncloud/SKILL.md, ~/.codex/skills/uncloud/SKILL.md, ~/.config/opencode/skills/uncloud/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall automatically invokes the skill installer., Installer targets existing Claude Code, Codex, and opencode agent skill directories., Installer recursively creates a skill directory and writes SKILL.md into those foreign agent control surfaces. - **Evidence against:** Postinstall exits without changes when CI=true or UNCLOUD\_SKIP\_SKILL=1., It avoids overwriting unmarked customized skills and leaves symlinked destinations alone., The inspected JavaScript has no credential harvesting or postinstall network request. ## 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.postinstall = node bin/postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node bin/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. High: Sandbox Evasion Gated Capability - **Category:** Source - **Confidence:** 84.0% - **Path:** bin/uncloud.js - **Public source:** [View source]() Source gates dangerous network, credential, or execution behavior behind CI, host, platform, time, or geo fingerprint checks. Public source snippet (untrusted): ```javascript L10: L11: const { spawnSync } = require("child_process"); L12: const path = require("path"); ...

Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** lib/skill.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L9: * Nothing is created speculatively. A directory is written only where that L10: * agent is already set up — installing uncloud never conjures a ~/.claude L11: * for someone who has never run Claude Code. ...

Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** vendor/darwin-amd64/uncloud - **Public source:** [View source]() Package ships native binary artifacts.
