This can modify project or global agent-skill directories without an explicit CLI command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-07-23T09:44:21.342Z - **Finished:** 2026-07-23T09:44:40.998Z - **Download time:** 514 ms - **Static scan time:** 2 ms - **AI review time:** 19140 ms - **Total time:** 19656 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation automatically invokes a Customer.io binary to install its agent skill. This can modify project or global agent-skill directories without an explicit CLI command. - **Trigger:** npm postinstall, globally or in the invoking project - **Impact:** Adds Customer.io skill-routing content to .agents or .claude control surfaces. - **Evidence paths:** package.json, .npm/postinstall.js, .npm/run.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-23T09:44:40.998Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time first-party agent-skill setup through platform binary - **Rationale:** This is an unconsented install-time, first-party agent-extension setup, not concrete malware. Source inspection found no direct exfiltration, destructive action, or remote-code chain in this package. - **Files touched:** .npm/postinstall.js, .npm/run.js, package.json, .agents/skills/\/, .claude/skills/\/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json defines postinstall., .npm/postinstall.js runs the platform cio binary during install., The postinstall invokes \`cio skills install --project\` or \`--global\`., README.md documents writes to .agents and .claude skill directories. - **Evidence against:** Wrapper contains no network, credential-read, eval, or file-write code., Execution is limited to the matching declared @customerio platform dependency., README.md identifies the installed item as the package's Customer.io bootstrap skill. ## Public findings ### 1.
