Installing the package automatically launches a platform-specific Customer.io binary to install agent skills. The binary is not included in this snapshot, so the resulting files cannot be verified here. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-09-04T05:24:12.685Z - **Finished:** 2026-09-04T05:24:52.005Z - **Download time:** 761 ms - **Static scan time:** 27 ms - **AI review time:** 38531 ms - **Total time:** 39320 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically launches a platform-specific Customer.io binary to install agent skills. The binary is not included in this snapshot, so the resulting files cannot be verified here. - **Trigger:** npm postinstall during a local or global package installation - **Impact:** It may modify the consumer project's or global agent-skill configuration without an explicit skills-install command. - **Evidence paths:** package.json, .npm/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T05:24:52.005Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic first-party agent-skill installation through a platform binary - **Rationale:** This package automatically invokes a skill installer during installation, creating a real agent-extension lifecycle risk. The inspected wrapper is otherwise bounded to Customer.io platform binaries and shows no direct exfiltration or payload behavior. - **Files touched:** package.json, .npm/postinstall.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs the bundled CLI's skills installer., For local installs it changes the child process directory to the consumer project and passes --project., For global installs it passes --global, allowing agent-skill setup outside the package directory. - **Evidence against:** The JavaScript wrapper selects only a matching Customer.io platform dependency., The inspected JavaScript contains no network request, credential harvesting, or shell evaluation., The observed action is a first-party CLI skill setup rather than a demonstrated payload or exfiltration chain. ## 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:** 91.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook automatically runs the bundled CLI's skills installer. Public source snippet (untrusted): ```json "bin": { "cio": ".npm/run.js" }, "scripts": { "postinstall": "node .npm/postinstall.js" } ``` ### 6. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** .npm/postinstall.js - **Public source:** [View source]() For local installs it changes the child process directory to the consumer project and passes --project. Public source snippet (untrusted): ```javascript const isGlobal = process.env.npm[redacted] === "true"; const scopeFlag = isGlobal ? "--global" : "--project"; const spawnOpts = { stdio: "inherit" }; // For project installs, npm runs postinstall with cwd inside node_modules. // INIT_CWD is the directory where the user ran npm install (the project root). if (!isGlobal && process.env.INIT_CWD) { spawnOpts.cwd = process.env.INIT_CWD; } 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:** 91.0% - **Path:** .npm/postinstall.js - **Public source:** [View source]() For global installs it passes --global, allowing agent-skill setup outside the package directory. Public source snippet (untrusted): ```javascript const isGlobal = process.env.npm[redacted] === "true"; const scopeFlag = isGlobal ? "--global" : "--project"; const spawnOpts = { stdio: "inherit" }; // For project installs, npm runs postinstall with cwd inside node_modules. // INIT_CWD is the directory where the user ran npm install (the project root). if (!isGlobal && process.env.INIT_CWD) { spawnOpts.cwd = process.env.INIT_CWD; } console.log(`[cio postinstall] Running: cio skills install ${scopeFlag}`); const child = spawn(binPath, ["skills", "install", scopeFlag], spawnOpts); ``` ## 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 0.0.26 (OptionalDependency) - @customerio/cli-darwin-x64 0.0.26 (OptionalDependency) - @customerio/cli-linux-arm64 0.0.26 (OptionalDependency) - @customerio/cli-linux-x64 0.0.26 (OptionalDependency) - @customerio/cli-win32-arm64 0.0.26 (OptionalDependency) - @customerio/cli-win32-x64 0.0.26 (OptionalDependency) ## Package metadata - **Package:** @customerio/cli - **Ecosystem:** npm - **Version:** 0.0.26 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-09-03T12:31:17.869Z - **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:** 17,768 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
