Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. A global npm install automatically runs this package's plugin installer, which registers the bundled c4a agent plugin for Claude, Codex, and Cursor. Local and CI installs skip that path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-22T17:00:40.452Z - **Finished:** 2026-09-22T17:02:04.003Z - **Download time:** 1024 ms - **Static scan time:** 10596 ms - **AI review time:** 71929 ms - **Total time:** 83551 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically runs this package's plugin installer, which registers the bundled c4a agent plugin for Claude, Codex, and Cursor. Local and CI installs skip that path. - **Trigger:** npm postinstall when the install is global or CONTEXT\_CLI\_AUTO\_PLUGIN\_INSTALL is 1. - **Impact:** User-level agent hosts gain this package's plugin and marketplace without a separate plugin install command. No credential send or remote code fetch was found in that path. - **Evidence paths:** package.json, scripts/postinstall.mjs, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T17:02:04.003Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.mjs spawns cli.js plugin install, whose default agent is all. That copies the bundled plugin and enables it in user Claude, Codex, and Cursor plugin locations, including Codex config.toml. - **Rationale:** Postinstall on a global install refreshes this package's own Claude, Codex, and Cursor plugins, which is first-party agent extension setup rather than a hidden payload. Local installs are skipped and the inspected hook does not exfiltrate credentials or execute a remote payload. - **Files touched:** ~/.claude/plugins/cache, ~/.claude/skills, ~/.codex/config.toml, ~/.cursor/plugins/local/c4a, ~/.agents/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers an npm postinstall script that runs scripts/postinstall.mjs., On a global install, or when CONTEXT\_CLI\_AUTO\_PLUGIN\_INSTALL is 1, postinstall spawns the bundled cli.js with plugin install., plugin install defaults the agent target to all and writes this package's c4a plugin into Claude, Codex, and Cursor user locations., Claude setup shells out to claude plugin marketplace add and plugin install --scope user; Codex rewrites config.toml to enable c4a@c4a. - **Evidence against:** Local dependency installs, CI, an explicit skip env, and a re-entry guard do not run the plugin refresh., The writes register this package's own marketplace and plugin id rather than fetching a remote payload or copying credentials. ## Affected versions and remediation This report applies to @c4a/context-cli@0.7.36. - Review the evidence and your use of @c4a/context-cli@0.7.36 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
