Unconsented control-surface mutation can cause installed AI agents to load package-provided instructions. - **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:** 1.10.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm installation automatically modifies multiple foreign AI-agent skill directories. It creates directories, removes matching prior skills, and links this package's skills into them. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-14T14:19:30.437Z - **Finished:** 2026-08-14T14:20:13.757Z - **Download time:** 260 ms - **Static scan time:** 46 ms - **AI review time:** 43013 ms - **Total time:** 43320 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation automatically modifies multiple foreign AI-agent skill directories. It creates directories, removes matching prior skills, and links this package's skills into them. - **Trigger:** npm postinstall - **Impact:** Unconsented control-surface mutation can cause installed AI agents to load package-provided instructions. - **Evidence paths:** package.json, bin/skills-link - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:20:13.757Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global symlink injection into agent skill directories - **Attack narrative:** During npm installation, the postinstall first checks all supported agent directories and, if any skill is absent or differs, reruns the linker globally. The linker creates agent skill directories, deletes existing matching skill directories or symlinks, and symlinks the package's skills into OpenCode, Claude, Codex, Cursor, and .agents locations without an explicit user command. - **Rationale:** This is a concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, meeting the blocking policy. No separate exfiltration chain is required for this verdict. - **Files touched:** package.json, bin/skills-link, skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install-time postinstall invokes the linker globally when its check finds drift., The linker targets five separate agent-control skill directories, including Claude, Codex, Cursor, and OpenCode., On install it removes existing same-named skill directories/symlinks and replaces them with package symlinks. - **Evidence against:** No network, credential harvesting, payload download, or shell-evaluation behavior is present in the lifecycle helper., The package content is Kubernetes skill documentation; the observed impact is the automatic broad agent-skill mutation. ## 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 = ./bin/skills-link --global --check > /dev/null 2>&1 || ./bin/skills-link --global ``` ### 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 = ./bin/skills-link --global --check > /dev/null 2>&1 || ./bin/skills-link --global ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 98.0% - **Path:** package.json - **Public source:** [View source]() Install-time postinstall invokes the linker globally when its check finds drift. Public source snippet (untrusted): ```json "scripts": { "postinstall": "./bin/skills-link --global --check > /dev/null 2>&1 || ./bin/skills-link --global", "skills-link": "./bin/skills-link" ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** bin/skills-link - **Public source:** [View source]() The linker targets five separate agent-control skill directories, including Claude, Codex, Cursor, and OpenCode. Public source snippet (untrusted): ```text # All known agent skill directories ALL_TARGETS=( "$HOME/.agents/skills" "$HOME/.config/opencode/skills" "$HOME/.claude/skills" "$HOME/.codex/skills" "$HOME/.cursor/skills" ) ``` ## 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:** k8s-agent-skills - **Ecosystem:** npm - **Version:** 1.10.0 - **License:** MIT - **Version published:** 2026-08-14T14:13:27.841Z - **Package first seen:** 2026-07-16T19:41:45.003Z - **Package last seen:** 2026-08-14T14:20:13.757Z - **Known versions:** 4 - **Latest version:** 1.10.0 - **Appeal under review:** No - **Description:** Agent skills for Kubernetes cluster operations — Cilium, Talos, Flux, Rook-Ceph, CNPG, Gitea, Tekton, Cert-Manager, VictoriaMetrics, ZITADEL, Harbor, Higress, KServe, Kubeflow, MariaDB, Vector, ExternalDNS, External Secrets, Vault, Dragonfly, Flagger, Sea - **Author:** Aidas - **Keywords:** ai-agent-skill, kubernetes, gitops, cilium, talos, flux, rook-ceph, postgresql, cnpg, gitea, tekton, cert-manager - **Runtime engines:** node: \>=18 - **Artifact files:** 78 - **Artifact unpacked size:** 636,664 bytes - **Artifact signatures:** 1 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
