Unconsented modification of multiple AI-agent control surfaces and persistent instruction injection. - **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:** 1.0.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically scans for installed AI-agent platforms and installs package-controlled skill files into all detected agent skill directories. The installed SKILL.md imposes mandatory agent behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-09T15:45:19.685Z - **Finished:** 2026-08-09T15:45:54.357Z - **Download time:** 517 ms - **Static scan time:** 142 ms - **AI review time:** 34012 ms - **Total time:** 34672 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically scans for installed AI-agent platforms and installs package-controlled skill files into all detected agent skill directories. The installed SKILL.md imposes mandatory agent behavior. - **Trigger:** npm installation of memory-store-skill - **Impact:** Unconsented modification of multiple AI-agent control surfaces and persistent instruction injection. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/install.js, SKILL.md, scripts/memory\_cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T15:45:54.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven broad AI-agent skill deployment - **Attack narrative:** Installing the package triggers postinstall, which launches install.js with --all without user confirmation. That script detects nine vendor-specific AI-agent configuration locations, creates each detected skill directory, and copies SKILL.md plus package scripts there. SKILL.md then supplies mandatory behavioral instructions to those agents. This is an unconsented, broad modification of foreign AI-agent control surfaces. - **Rationale:** The package has a concrete automatic postinstall chain that installs its agent instructions into every detected supported platform. Local-only CLI behavior does not mitigate that unconsented control-surface mutation. - **Files touched:** scripts/postinstall.js, scripts/install.js, SKILL.md, ~/.claude/skills/memory-store, ~/.agents/skills/memory-store, ~/.gemini/skills/memory-store, ~/.config/opencode/skills/memory-store, ~/.workbuddy/skills/memory-store, ~/.cursor/skills/memory-store, ~/.windsurf/skills/memory-store, ~/.qoderworkcn/skills/memory-store, ~/.trae-cn/skills/memory-store, ~/.memory-store/memories.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall.js executes install.js --all., scripts/install.js detects nine unrelated AI-agent config roots and copies this skill into each., SKILL.md contains mandatory agent-behavior instructions that claim to override normal workflow. - **Evidence against:** No network, credential harvesting, or remote payload execution found., memory\_cli.js is local JSON memory storage/retrieval using Node built-ins. ## 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 scripts/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 scripts/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. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** memory-store-skill - **Ecosystem:** npm - **Version:** 1.0.3 - **License:** MIT - **Version published:** 2026-08-07T09:57:29.531Z - **Package first seen:** 2026-08-06T02:55:03.812Z - **Package last seen:** 2026-08-13T03:25:42.080Z - **Known versions:** 4 - **Latest version:** 1.1.1 - **Appeal under review:** No - **Description:** Conversation memory skill for multi-agent AI workflows — store, share, and recall across sessions and agents - **Author:** xws - **Keywords:** memory, agent, ai, claude, skill, conversation, llm, multi-agent, memory-store, codex, claude-code, opencode - **Runtime engines:** node: \>=18 - **Artifact files:** 13 - **Artifact unpacked size:** 127,395 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
