Installation conditionally writes a Tigris skill into an existing Claude Code skills directory. The installed skill can influence future agent selection of storage commands, but no concrete malicious payload or exfiltration chain was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-03T10:03:36.361Z - **Finished:** 2026-08-03T10:04:04.446Z - **Download time:** 1018 ms - **Static scan time:** 174 ms - **AI review time:** 26890 ms - **Total time:** 28085 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation conditionally writes a Tigris skill into an existing Claude Code skills directory. The installed skill can influence future agent selection of storage commands, but no concrete malicious payload or exfiltration chain was found. - **Trigger:** npm postinstall when ~/.claude already exists - **Impact:** Unconsented first-party agent-extension setup may steer Claude Code toward Tigris operations. - **Evidence paths:** package.json, postinstall.cjs, SKILL.md, dist/chunk-3QCSRNXC.js, dist/chunk-VNUR4TRP.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T10:04:04.446Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** copies package-owned non-user-invocable Claude Code skill - **Rationale:** This is an unconsented but package-owned agent-extension lifecycle action, warranting a warning under policy. Direct inspection found no concrete malicious behavior. - **Files touched:** postinstall.cjs, SKILL.md, ~/.claude/skills/tigris/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall.cjs on install., postinstall.cjs copies SKILL.md to ~/.claude/skills/tigris/SKILL.md when ~/.claude exists., SKILL.md is non-user-invocable and directs Claude Code to prefer Tigris, including storage write/delete commands. - **Evidence against:** The install hook performs no network request, shell execution, credential read, or payload download., The copied file is a package-owned Tigris skill, not a broad Claude configuration rewrite., SKILL.md contains CLI reference material; no prompt-escape, exfiltration, or covert instruction was found., Network and credential handling in dist is tied to explicit Tigris CLI authentication/storage operations. ## Public findings ### 1.
