On npm postinstall, the package writes its bundled Tigris Claude Code skill into an existing global Claude skills directory. No install-time network or payload execution was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 92.0% - **Started:** 2026-08-24T07:12:32.973Z - **Finished:** 2026-08-24T07:13:30.949Z - **Download time:** 512 ms - **Static scan time:** 297 ms - **AI review time:** 57163 ms - **Total time:** 57976 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package writes its bundled Tigris Claude Code skill into an existing global Claude skills directory. No install-time network or payload execution was confirmed. - **Trigger:** npm postinstall when ~/.claude exists - **Impact:** Influences Claude Code's storage-tool preference. - **Evidence paths:** postinstall.cjs, SKILL.md, dist/chunk-RQGIXHG5.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T07:13:30.949Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** same-vendor global AI-agent skill installation - **Rationale:** This is a guarded first-party agent extension lifecycle risk, not a concrete malicious chain. The package should warn rather than block. - **Files touched:** postinstall.cjs, SKILL.md, ~/.claude/skills/tigris/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall copies bundled SKILL.md into an existing Claude Code global skills directory., Bundled skill directs agents to prefer Tigris for object-storage tasks. - **Evidence against:** The postinstall hook makes no network request or command execution., The install-time write is limited to a same-vendor Tigris skill and only when ~/.claude already exists., Broader MCP/editor configuration writes occur only through interactive \`tigris init\`. ## Public findings ### 1.
