On dependency installation, the package conditionally adds a bundled Tigris skill to an existing Claude Code global skills directory. No install-time network or command execution beyond Node file operations was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-18T10:09:02.516Z - **Finished:** 2026-08-18T10:09:53.359Z - **Download time:** 756 ms - **Static scan time:** 291 ms - **AI review time:** 49792 ms - **Total time:** 50843 ms ## Security analysis ### Published attack-surface review - **Summary:** On dependency installation, the package conditionally adds a bundled Tigris skill to an existing Claude Code global skills directory. No install-time network or command execution beyond Node file operations was found. - **Trigger:** npm dependency installation where ~/.claude already exists - **Impact:** Adds persistent first-party agent guidance without an explicit setup command. - **Evidence paths:** package.json, postinstall.cjs, SKILL.md, dist/chunk-L6I5MSYU.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T10:09:53.359Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded postinstall copy into a Claude Code skill directory - **Rationale:** This is a real, unconsented install-time mutation of an AI-agent control surface, but it is narrowly scoped to a pre-existing Claude installation and copies a bundled first-party skill. It meets the lifecycle-risk warning boundary rather than concrete malicious behavior. - **Files touched:** postinstall.cjs, SKILL.md, ~/.claude/skills/tigris/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** A postinstall lifecycle hook runs automatically on dependency installation., Postinstall copies the packaged SKILL.md into an existing global Claude Code skills directory., The installed skill is non-user-invocable and directs agents to prefer Tigris for object-storage tasks. - **Evidence against:** The postinstall action is guarded by the pre-existing ~/.claude directory and only copies a bundled local file., No install-time network request, shell execution, credential harvesting, or payload download is present., Broader MCP and agent configuration changes occur through the explicit interactive \`tigris init\` command, not postinstall. ## Public findings ### 1.
