## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates an existing consumer Claude Code control surface without an explicit setup command. It deploys launcher and hook-capable scripts from the package into the project.

- **Trigger:** npm install of moflo in a project containing .claude

- **Impact:** Unconsented installation/update of Claude Code session-start and hook control code.

- **Evidence paths:** package.json, scripts/post-install-bootstrap.mjs, scripts/post-install-notice.mjs, bin/lib/shipped-scripts.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-10T07:47:02.211Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Copies package scripts and helpers into consumer .claude directories

- **Attack narrative:** During npm postinstall, the bootstrap checks for an existing consumer .claude directory and then copies a manifest-selected set of package scripts, including session-start-launcher.mjs and hook-related helpers, into that foreign Claude Code control surface. This occurs without the user invoking the package's setup command.

- **Rationale:** The package has a concrete, unconsented postinstall path that writes broad AI-agent launcher and hook code into an existing project control surface. This meets the install-control-surface block boundary despite no observed exfiltration.

- **Files touched:** \<project\>/.claude/scripts/, \<project\>/.claude/scripts/lib/, \<project\>/.claude/scripts/migrations/, \<project\>/.claude/helpers/, \<project\>/.moflo/bootstrap-failed.json

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall automatically., scripts/post-install-bootstrap.mjs writes into consumer .claude., bin/lib/shipped-scripts.json includes session-start launcher and hook helpers., Bootstrap activates whenever an existing .claude directory is found.

- **Evidence against:** Postinstall source shows no network or credential exfiltration., Native pruner is ownership-scoped to onnxruntime-node artifacts.
