The install hook invokes \`skyline setup\`, which documentation says configures a Skyline daemon and agent plugins. The wrapper source itself contains no confirmed network, harvesting, or destructive behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-07-13T12:44:39.647Z - **Finished:** 2026-07-13T12:45:23.409Z - **Download time:** 517 ms - **Static scan time:** 18 ms - **AI review time:** 43226 ms - **Total time:** 43762 ms ## Security analysis ### Published attack-surface review - **Summary:** The install hook invokes \`skyline setup\`, which documentation says configures a Skyline daemon and agent plugins. The wrapper source itself contains no confirmed network, harvesting, or destructive behavior. - **Trigger:** npm postinstall runs without \`CI\` or \`SKYLINE\_NO\_AUTO\_SETUP\`; alternatively a user runs \`skyline setup\`. - **Impact:** May alter local Skyline-owned service and agent-plugin configuration; the platform binary implementation is not present in this package. - **Evidence paths:** package.json, postinstall.js, bin.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-13T12:45:23.409Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-triggered first-party daemon and AI-agent plugin setup via platform binary - **Rationale:** Source supports a real install-time first-party agent-extension/daemon setup risk, not a concrete malicious chain. The scanner fingerprint alone is insufficient to block this package. - **Files touched:** package.json, postinstall.js, bin.js, README.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** \`package.json\` defines \`postinstall\`., \`postinstall.js\` automatically invokes \`bin.js setup\` outside CI unless opted out., \`README.md\` states setup installs an autostart daemon and agent marketplace plugins., \`README.md\` describes plugin hooks that redirect built-in Claude tools to Skyline MCP tools. - **Evidence against:** \`postinstall.js\` is best-effort, opt-out, and does not itself write files or send network requests., \`bin.js\` only resolves a platform sibling package and forwards user arguments to its binary., No credential harvesting, exfiltration, eval, dynamic code loading, or network client appears in the inspected JavaScript., No concrete malicious payload or destructive command appears in the inspected package files. ## 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 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 postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** bin.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = malicious_source_fingerprint_signature signature = 202b3dfd3937dab6 signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = @skylence-ai/skyline@1.0.73 matchedPath = bin.js matchedIdentity = npm:QHNreWxlbmNlLWFpL3NreWxpbmU:1.0.73 similarity = 1.000 shingleOverlap = 2 summary = package final verdict is malicious ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @skylence-ai/skyline - **Ecosystem:** npm - **Version:** 1.0.74 - **License:** Apache-2.0 - **Version published:** 2026-07-13T12:35:47.639Z - **Package first seen:** 2026-07-01T13:28:02.061Z - **Package last seen:** 2026-08-15T19:27:10.519Z - **Known versions:** 23 - **Latest version:** 1.2.5 - **Appeal under review:** No ## References - [HTML security report]()
