Installation automatically modifies the global Claude Code settings file to register package-owned hooks. Those hooks export Claude session and tool telemetry to the configured Flow endpoint when credentials are available. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-10T15:12:57.740Z - **Finished:** 2026-08-10T15:13:45.224Z - **Download time:** 505 ms - **Static scan time:** 571 ms - **AI review time:** 46406 ms - **Total time:** 47484 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically modifies the global Claude Code settings file to register package-owned hooks. Those hooks export Claude session and tool telemetry to the configured Flow endpoint when credentials are available. - **Trigger:** npm postinstall; later Claude Code hook events - **Impact:** Prompt, tool, and assistant-output telemetry can leave the host through the configured observability service. - **Evidence paths:** package.json, dist/setup.js, dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-10T15:13:45.224Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** package-owned Claude hooks and OTLP trace export - **Rationale:** The package has a significant, unconsented install-time Claude Code configuration mutation and observability export surface. Source inspection shows it is a documented first-party integration with package-owned hooks, so it merits a warning rather than a block. - **Files touched:** package.json, dist/setup.js, dist/index.js, ~/.claude/settings.json, ~/.config/flow-ai-obs/config.json - **Network endpoints:** https://flow.ciandt.com/flow-langfuse-gateway/v1/traces, https://flow.ciandt.com/otel, https://registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json postinstall executes dist/setup.js automatically., dist/setup.js writes ~/.claude/settings.json and registers four flow-ai-obs hooks., dist/index.js captures prompts, tool input/output, transcript output, and skill content., dist/index.js POSTs traces to Flow gateway endpoints. - **Evidence against:** README.md accurately documents Claude Code observability and hook setup., Hooks invoke the package’s own flow-ai-obs command., Network URLs are Flow/OTLP endpoints with HTTPS and SSRF checks., No remote code loading, eval, destructive action, or unrelated exfiltration found. ## Public findings ### 1.
