Installation automatically invokes a Customer.io CLI subcommand that installs an agent skill. This can alter project or global agent-skill directories, but the inspected wrapper shows no exfiltration or destructive action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-28T16:51:19.770Z - **Finished:** 2026-08-28T16:51:54.488Z - **Download time:** 774 ms - **Static scan time:** 8 ms - **AI review time:** 33935 ms - **Total time:** 34718 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically invokes a Customer.io CLI subcommand that installs an agent skill. This can alter project or global agent-skill directories, but the inspected wrapper shows no exfiltration or destructive action. - **Trigger:** Installing the package with npm on a supported platform. - **Impact:** A project may receive a Customer.io agent-skill entry, or a global install may affect agent-skill configuration for future projects. - **Evidence paths:** package.json, .npm/postinstall.js, .npm/run.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T16:51:54.488Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Post-install execution of the bundled platform CLI with a skill-install command. - **Rationale:** This is an automatic first-party agent-extension setup, which warrants a warning under the lifecycle policy. The inspected source does not establish malicious behavior or a foreign broad control-surface takeover. - **Files touched:** .npm/postinstall.js, package.json, ./.claude, ./.agents, ~/.claude, ~/.agents ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The package runs a post-install hook automatically., The hook launches the platform CLI to install an agent skill into the project or global scope without an interactive command., The included documentation identifies the affected Claude and open-agent skill directories. - **Evidence against:** The wrapper resolves only a pinned same-vendor platform package before launching its binary., The inspected JavaScript contains no network requests, credential harvesting, obfuscation, or self-dependency., The post-install hook exits harmlessly when no matching platform binary is available. ## 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 package runs a post-install hook automatically. Public source snippet (untrusted): ```json "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]() The hook launches the platform CLI to install an agent skill into the project or global scope without an interactive command. 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:** README.md - **Public source:** [View source]() The included documentation identifies the affected Claude and open-agent skill directories. Public source snippet (untrusted): ````markdown # Installs the bootstrap skill; prompts for global (~/.claude, ~/.agents) # vs. project (./.claude, ./.agents) cio skills install cio skills install --global # install for every project cio skills install --project # install into the current directory cio skills install --target claude # Claude Code only (use --target codex for Codex) cio skills install --dry-run # show what would be written cio skills install --force # overwrite an existing SKILL.md ``` This installs only the Customer.io bootstrap skill — its `SKILL.md` routing index is written to `< ```` ## 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 0.0.24 (OptionalDependency) - @customerio/cli-darwin-x64 0.0.24 (OptionalDependency) - @customerio/cli-linux-arm64 0.0.24 (OptionalDependency) - @customerio/cli-linux-x64 0.0.24 (OptionalDependency) - @customerio/cli-win32-arm64 0.0.24 (OptionalDependency) - @customerio/cli-win32-x64 0.0.24 (OptionalDependency) ## Package metadata - **Package:** @customerio/cli - **Ecosystem:** npm - **Version:** 0.0.24 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-08-28T16:35:28.752Z - **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]()
