Future Claude Code sessions can be influenced to use Tigris for object-storage tasks without the user's explicit setup action. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 3.11.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation automatically modifies an existing Claude Code control surface. It installs a non-user-invocable skill that steers future agent behavior toward this package's service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-01T14:44:34.695Z - **Finished:** 2026-09-01T14:45:15.311Z - **Download time:** 1020 ms - **Static scan time:** 346 ms - **AI review time:** 39247 ms - **Total time:** 40616 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically modifies an existing Claude Code control surface. It installs a non-user-invocable skill that steers future agent behavior toward this package's service. - **Trigger:** npm installation runs the postinstall hook when the user's .claude directory exists. - **Impact:** Future Claude Code sessions can be influenced to use Tigris for object-storage tasks without the user's explicit setup action. - **Evidence paths:** package.json, postinstall.cjs, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-01T14:45:15.311Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic installation of a Claude Code skill into the user's home directory. - **Attack narrative:** The package registers a postinstall lifecycle hook. On dependency installation, it detects an existing Claude Code directory and copies its bundled non-user-invocable skill into the user's global Claude skills directory. That skill instructs the agent to use Tigris for all object-storage tasks, creating an unconsented cross-session agent control surface. - **Rationale:** This is an automatic postinstall mutation of a foreign AI-agent control surface, not an explicit user-command setup flow. The hook installs behavioral instructions that influence future agent actions. - **Files touched:** postinstall.cjs, SKILL.md, .claude/skills/tigris/SKILL.md - **Network endpoints:** https://t3.storage.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs postinstall automatically., The install hook copies a package skill into the user's Claude Code skills directory when .claude exists., The installed skill is non-user-invocable and directs the agent to prefer Tigris for all object-storage work. - **Evidence against:** The hook does not show credential collection, network access, or shell execution., Other agent configuration changes are behind the interactive tigris init command. ## Public findings ### 1.
