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 installation automatically refreshes this package's bundled Codex, Cursor, and Claude integrations. It modifies user-level agent plugin locations and Codex configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-10T02:01:28.255Z - **Finished:** 2026-09-10T02:02:53.374Z - **Download time:** 763 ms - **Static scan time:** 14134 ms - **AI review time:** 70217 ms - **Total time:** 85119 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 installation automatically refreshes this package's bundled Codex, Cursor, and Claude integrations. It modifies user-level agent plugin locations and Codex configuration. - **Trigger:** Global npm installation of the package, or the explicit auto-install environment override. - **Impact:** User-level agent configuration and plugin caches can be changed without a separate plugin-install command. - **Evidence paths:** scripts/postinstall.mjs, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-10T02:02:53.374Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven installation of bundled agent plugins and configuration. - **Rationale:** This is a guarded, first-party agent-extension setup performed automatically during global installation, which warrants a warning under the lifecycle policy. The inspected source does not establish malicious payload delivery, secret collection, or network exfiltration. - **Files touched:** scripts/postinstall.mjs, cli.js, ~/.codex/config.toml, ~/.codex/plugins/cache/context4ai/c4a, ~/.cursor/plugins/local/c4a, ~/.claude/plugins/cache ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall lifecycle script., On global installation, the lifecycle script automatically invokes the bundled plugin installer., The installer writes a local marketplace entry and enables its plugin in the Codex user configuration., It also copies bundled plugins into Cursor and installs a user-scoped Claude plugin. - **Evidence against:** The lifecycle script skips ordinary local dependency installs and CI, unless an explicit override is set., No self-dependency is declared in package.json., Static inspection found no DNS, HTTP, or credential-exfiltration implementation; the DNS hint matches an internal forbidden-module list. ## Affected versions and remediation This report applies to @c4a/context-cli@0.7.8. - Review the evidence and your use of @c4a/context-cli@0.7.8 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.
