Those hooks capture Claude session inputs for telemetry. - **Trigger:** npm install - **Impact:** Foreign AI-agent settings are modified and prompt/session data becomes available to package telemetry handlers. - **Evidence paths:** package.json, dist/setup.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T14:44:18.338Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented Claude Code hook registration via postinstall - **Attack narrative:** Installing the package runs dist/setup.js. Its startup calls the configuration writer before checking whether credentials exist, then creates or updates ~/.claude/settings.json and adds hooks for prompt, tool, and stop events. The installed handler records submitted prompts and session context for the package's telemetry flow. This is an unprompted install-time mutation of the foreign Claude Code control surface. - **Rationale:** The package has a concrete, manifest-reachable postinstall chain that silently registers hooks in Claude Code settings. Package-aligned telemetry does not remove the unconsented foreign AI-agent configuration mutation. - **Files touched:** package.json, dist/setup.js, dist/index.js, ~/.claude/settings.json, ~/.claude/settings.json.bkp, ~/.claude/settings.json.lock - **Network endpoints:** https://flow.ciandt.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall directly executes dist/setup.js., Setup invokes configuration before checking credentials., Setup writes ~/.claude/settings.json and registers four flow-ai-obs hooks., Hook handler captures submitted prompt and session context. - **Evidence against:** Default telemetry host is package-aligned flow.ciandt.com., README describes an explicit init command, though installation already mutates Claude settings. ## Public findings ### 1.
