Foreign user agent control files for Claude, Codex, and Cursor are created or rewritten as a side effect of installing the package globally. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.7.35 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm install runs postinstall, which launches plugin install for Claude, Codex, and Cursor. That command writes user-level agent plugin configuration and skill directories without a separate plugin command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-22T17:00:40.636Z - **Finished:** 2026-09-22T17:02:37.982Z - **Download time:** 1008 ms - **Static scan time:** 10412 ms - **AI review time:** 105925 ms - **Total time:** 117346 ms The recorded confidence comes from the underlying analysis.

That command writes user-level agent plugin configuration and skill directories without a separate plugin command. - **Trigger:** npm postinstall when npm\_config\_global is set or CONTEXT\_CLI\_AUTO\_PLUGIN\_INSTALL is 1. - **Impact:** Foreign user agent control files for Claude, Codex, and Cursor are created or rewritten as a side effect of installing the package globally. - **Evidence paths:** package.json, scripts/postinstall.mjs, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T17:02:37.982Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.mjs spawnSyncs the bundled cli.js with plugin install. The default agent is all, which installs a user-scoped Claude plugin, enables a Codex plugin in config.toml, copies a Cursor user plugin, and materializes provider skills under home agent directories. - **Attack narrative:** On a global npm install, postinstall starts the bundled CLI with plugin install and no agent flag. The command treats the target as all and registers this package in the user Claude plugin scope, enables it in the Codex config file, copies a Cursor user plugin, and writes skills under the home agent skill directories. Local and CI installs are skipped, but the global path does not require a separate plugin command. Installing the package therefore mutates several foreign agent control surfaces. - **Rationale:** The postinstall hook automatically runs a broad plugin install into Claude, Codex, and Cursor user configuration during a global package install. That is unconsented lifecycle mutation of foreign agent control surfaces, so the package should be blocked. - **Files touched:** .claude, plugins/cache, .claude/skills, .codex, config.toml, .cursor/plugins/local, .agents/skills, .agents ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json postinstall runs scripts/postinstall.mjs on install., A global npm install or CONTEXT\_CLI\_AUTO\_PLUGIN\_INSTALL spawns the bundled CLI as plugin install without a separate user plugin command., plugin install defaults the agent target to all, which selects claude, codex, and cursor., That install path registers a user-scoped Claude plugin, writes Codex config.toml, copies a Cursor user plugin, and materializes skills under home agent directories. - **Evidence against:** CI, re-entry, CONTEXT\_CLI\_SKIP\_PLUGIN\_INSTALL, and ordinary local dependency installs skip the plugin refresh., The package is an agent-integration CLI, and the same plugin install command is also exposed for an explicit user run., Refresh failures are logged and the hook does not download a remote payload. ## Affected versions and remediation This report applies to @c4a/context-cli@0.7.35. - Avoid installing @c4a/context-cli@0.7.35. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
