Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. This release is the Mastra Code agent SDK with ordinary build scripts and no npm lifecycle hooks. File writes, shell use, and PostHog telemetry are caller-invoked product features rather than a hidden install attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-27T20:07:54.422Z - **Finished:** 2026-09-27T20:08:44.213Z - **Download time:** 1036 ms - **Static scan time:** 994 ms - **AI review time:** 47760 ms - **Total time:** 49791 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:** No install-time or import-time attack was identified. Shell and file writes belong to the coding-agent SDK and run only when a caller uses those features. - **Trigger:** No automatic install or import trigger. Agent tools and settings writes run only when application code calls them. - **Impact:** No unconsented credential theft, remote payload execution, persistence, or foreign agent-control mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-27T20:08:44.213Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle scripts are absent. Settings are written to the package app-data settings file, and telemetry is optional product analytics to PostHog. - **Rationale:** This release is the Mastra Code agent SDK with ordinary build scripts and no npm lifecycle hooks. File writes, shell use, and PostHog telemetry are caller-invoked product features rather than a hidden install attack. - **Network endpoints:** https://us.posthog.com ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no preinstall, install, or postinstall hooks; scripts are only build, typecheck, test, and lint., dist/index.js is a library entry that imports the Mastra coding-agent SDK and related local modules, with no install-time side effect., saveSettings writes JSON under the package settings path returned by getSettingsPath, which joins the app data directory and settings.json., Product telemetry posts usage metadata to us.posthog.com and is turned off when MASTRA\_TELEMETRY\_DISABLED is set. - **Evidence against:** Shell spawn, git, clipboard, LSP, and hook execution exist for coding-agent features and are not tied to an npm lifecycle script., The package does not depend on its own name and does not mutate foreign agent control files at install time. ## Affected versions and remediation This report applies to @mastra/code-sdk@1.5.0. - Review the evidence and your use of @mastra/code-sdk@1.5.0 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.
