It targets global or invoking-project scope; the included wrapper does not itself show the resulting writes. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-21T21:50:09.633Z - **Finished:** 2026-08-21T21:50:47.465Z - **Download time:** 762 ms - **Static scan time:** 9 ms - **AI review time:** 37060 ms - **Total time:** 37832 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically launches the optional Customer.io platform binary to install an agent skill. It targets global or invoking-project scope; the included wrapper does not itself show the resulting writes. - **Trigger:** npm installation of @customerio/cli - **Impact:** May add a Customer.io bootstrap skill under agent configuration directories without an explicit CLI command. - **Evidence paths:** package.json, .npm/postinstall.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-21T21:50:47.465Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-triggered first-party agent skill installation - **Rationale:** This is a documented first-party agent-extension setup, not a demonstrated malicious chain, but it is automatically invoked at install time and affects agent configuration locations. Treat it as a lifecycle risk requiring a warning. - **Files touched:** .npm/postinstall.js, bin/cio, ~/.claude, ~/.agents, ./.claude, ./.agents ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Install-time postinstall hook executes automatically., Postinstall invokes the platform CLI with \`skills install\`., The hook chooses global or project scope and sets project cwd to INIT\_CWD., README states this installs a Customer.io agent bootstrap skill into \`.claude\` or \`.agents\` targets. - **Evidence against:** Wrapper source contains no network, credential-harvesting, eval, or file-write logic., Executed binary is selected only from declared same-package optional platform dependencies., Skill setup is documented as a Customer.io CLI feature, indicating first-party extension setup rather than stealth. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node .npm/postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node .npm/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 5. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Install-time postinstall hook executes automatically. Public source snippet (untrusted): ```json "scripts": { "postinstall": "node .npm/postinstall.js" } ``` ### 6. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 90.0% - **Path:** .npm/postinstall.js - **Public source:** [View source]() Postinstall invokes the platform CLI with \`skills install\`. Public source snippet (untrusted): ```javascript console.log(`[cio postinstall] Running: cio skills install ${scopeFlag}`); const child = spawn(binPath, ["skills", "install", scopeFlag], spawnOpts); ``` ### 7. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** README.md - **Public source:** [View source]() README states this installs a Customer.io agent bootstrap skill into \`.claude\` or \`.agents\` targets. Public source snippet (untrusted): ```markdown This installs only the Customer.io bootstrap skill — its `SKILL.md` routing index is written to `/skills//` for Claude Code (`.claude`) and the open agent skills convention (`.agents`) Codex, Cursor, and Windsurf read. ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 6 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 6 ### Published dependency entries - @customerio/cli-darwin-arm64 0.0.22 (OptionalDependency) - @customerio/cli-darwin-x64 0.0.22 (OptionalDependency) - @customerio/cli-linux-arm64 0.0.22 (OptionalDependency) - @customerio/cli-linux-x64 0.0.22 (OptionalDependency) - @customerio/cli-win32-arm64 0.0.22 (OptionalDependency) - @customerio/cli-win32-x64 0.0.22 (OptionalDependency) ## Package metadata - **Package:** @customerio/cli - **Ecosystem:** npm - **Version:** 0.0.22 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-08-20T15:02:18.195Z - **Package first seen:** 2026-07-03T00:00:52.435Z - **Package last seen:** 2026-09-04T05:24:52.005Z - **Known versions:** 6 - **Latest version:** 0.0.26 - **Appeal under review:** No - **Description:** Agent-first CLI for Customer.io APIs - **Maintainers:** ami-ci, ansible-runner - **Runtime engines:** node: \>=16 - **Artifact files:** 5 - **Artifact unpacked size:** 17,678 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
