A consumer who only installed the CLI globally gets this package's plugins and skills registered in Claude, Codex, and Cursor user control surfaces without a separate install command. - **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:** 0.7.38 - **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 context plugin install with the default agent all. That refreshes Claude, Codex, and Cursor user-level plugin and skill configuration from the bundled marketplace. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-25T20:21:22.849Z - **Finished:** 2026-09-25T20:22:57.654Z - **Download time:** 1762 ms - **Static scan time:** 10812 ms - **AI review time:** 82230 ms - **Total time:** 94805 ms The recorded confidence comes from the underlying analysis.

That refreshes Claude, Codex, and Cursor user-level plugin and skill configuration from the bundled marketplace. - **Trigger:** npm postinstall when npm\_config\_global is set, or when CONTEXT\_CLI\_AUTO\_PLUGIN\_INSTALL=1. - **Impact:** A consumer who only installed the CLI globally gets this package's plugins and skills registered in Claude, Codex, and Cursor user control surfaces without a separate install command. - **Evidence paths:** package.json, scripts/postinstall.mjs, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-25T20:22:57.654Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.mjs spawnSyncs the bundled cli.js as plugin install. The command defaults to all hosts, then calls the claude and codex CLIs and copies plugin files into home agent directories. - **Attack narrative:** On a global install, postinstall skips only CI, re-entry, and an explicit opt-out, then runs the bundled CLI as plugin install. That command defaults to every supported agent. It registers the bundled marketplace with Claude at user scope, enables the Codex plugin and rewrites Codex config, and copies Cursor and shared skill trees into the user home. Local project installs do not take this path, but a normal global install does, so three foreign agent control surfaces change without a separate plugin command. - **Rationale:** Postinstall on a global install unconditionally launches plugin install, and that command defaults to mutating Claude, Codex, and Cursor user configuration together. That is an unconsented lifecycle write across a broad foreign agent control surface, not a user-invoked single-host setup. - **Files touched:** ~/.claude/skills, ~/.claude/plugins/cache, ~/.agents/skills, ~/.codex/config.toml, ~/.cursor/plugins/local ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json registers a postinstall hook that runs scripts/postinstall.mjs., On a global npm install, or when CONTEXT\_CLI\_AUTO\_PLUGIN\_INSTALL is 1, postinstall chooses action install; CI, re-entry, and an explicit skip variable are the main gates., That install path spawns the bundled cli.js with plugin install and no agent argument., The plugin install command defaults --agent to all, and selectedAgents expands all to claude, codex, and cursor., Install writes user-level skill and plugin directories under the home .claude, .agents, and .cursor trees, and Codex config under .codex., The Claude path invokes the claude CLI to add this package marketplace and install the plugin with --scope user. - **Evidence against:** Local dependency installs and CI are skipped unless the force variable is set., CONTEXT\_CLI\_SKIP\_PLUGIN\_INSTALL=1 is an explicit opt-out, and a re-entry variable prevents the spawned CLI from looping., The written content is this package's bundled plugin tree, not a downloaded payload. ## Affected versions and remediation This report applies to @c4a/context-cli@0.7.38. - Avoid installing @c4a/context-cli@0.7.38. 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.
