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. The package has no install lifecycle hook, and the reviewed agent-skill writes occur during the documented CLI onboarding flow and are limited to skills shipped by this package. Authentication uses a user-approved device flow; telemetry is disclosed and can be disabled, while repository migration is user-directed and warns about sensitive Git metadata and conversation history. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-29T07:21:36.840Z - **Finished:** 2026-10-29T07:22:39.874Z - **Download time:** 771 ms - **Static scan time:** 352 ms - **AI review time:** 61910 ms - **Total time:** 63034 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 attack identified. The package performs documented sign-in, CLI setup, skill installation, and usage telemetry when its CLI is invoked. - **Trigger:** User invokes the CLI onboarding command; repo transfer behavior is described in a skill intended for an explicit migration request. - **Impact:** No evidence of credential theft or unauthorized account actions. Expected effects include local skill and credential files, telemetry, and repository transfer during an intentional migration. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T07:22:39.874Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI authenticates through the configured Instabox API, copies its own skills into user skill directories, and sends usage events to PostHog. Migration scripts transfer selected repository data to a user-created box. - **Rationale:** The package has no install lifecycle hook, and the reviewed agent-skill writes occur during the documented CLI onboarding flow and are limited to skills shipped by this package. Authentication uses a user-approved device flow; telemetry is disclosed and can be disabled, while repository migration is user-directed and warns about sensitive Git metadata and conversation history. - **Files touched:** ~/.claude/skills/\/, ~/.agents/skills/\/, ${XDG\_CONFIG\_HOME}/instabox/credentials.json, ${XDG\_CONFIG\_HOME}/instabox/telemetry.json, \ - **Network endpoints:** api.instabox.sh, us.i.posthog.com ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares no install, preinstall, or postinstall hook., The CLI installs only the skills shipped with this package under the documented Claude and agent skill directories; it supports --no-skills and only overwrites copies marked as installed by instabox., Onboarding runs for the documented bare CLI invocation or sh command; other arguments are passed to the CLI., Sign-in uses a device-code flow that presents a verification page and waits for the user’s approval., Telemetry sends usage events to PostHog; the CLI says events contain steps and outcomes, not names or arguments, and documents opt-out variables., The repo-migration skill warns that Git metadata can include token-bearing remote URLs and asks the user about copying conversation history that may contain secrets. - **Evidence against:** Onboarding writes package skills into ~/.claude/skills and ~/.agents/skills, which are outside the package directory., Onboarding sends usage telemetry by default to us.i.posthog.com., The migration skill can transfer .git data, including a remote URL with an embedded token, when the user requests migration. ## Affected versions and remediation This report applies to instabox@0.8.40. - Review the evidence and your use of instabox@0.8.40 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.
