Future Claude sessions and prompts execute package-controlled local commands without an explicit setup action. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.34.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. On npm installation, the package detects AI clients, copies its skill into their user directories, and modifies Claude's global settings. It creates SessionStart and UserPromptSubmit command hooks that execute later across projects. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T05:43:22.768Z - **Finished:** 2026-09-14T05:44:14.521Z - **Download time:** 511 ms - **Static scan time:** 233 ms - **AI review time:** 51008 ms - **Total time:** 51753 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package detects AI clients, copies its skill into their user directories, and modifies Claude's global settings. It creates SessionStart and UserPromptSubmit command hooks that execute later across projects. - **Trigger:** npm postinstall when Claude is detected and Python is available. - **Impact:** Future Claude sessions and prompts execute package-controlled local commands without an explicit setup action. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T05:44:14.521Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent hook installation. - **Attack narrative:** Installing the package automatically runs postinstall. When Claude is detected, it copies package content into the user's Claude skill directory and adds global SessionStart and UserPromptSubmit command hooks to Claude settings. Those hooks invoke the installed validator during later agent activity. The package does not require an explicit setup command or prompt before changing this broad agent control surface. - **Rationale:** The package performs unconsented postinstall mutation of a user-level AI-agent control surface and establishes future command execution. This meets the install-hook abuse blocking policy despite no observed network exfiltration. - **Files touched:** ~/.claude/settings.json, ~/.claude/skills/agentic-sdlc-skill, ~/.agentic-sdlc/orient-hook-wired, ~/.agentic-sdlc/remind-hook-wired ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Automatic postinstall runs package code., Postinstall copies the skill into detected AI-client directories., Postinstall silently adds global Claude SessionStart and UserPromptSubmit command hooks., Those hooks invoke the installed Python validator for future sessions and prompts. - **Evidence against:** No network endpoints or credential-exfiltration code were found., The hook commands point to the package's local validator, not a remote payload. ## Affected versions and remediation This report applies to @antoneeo/agentic-sdlc-skill@1.34.0. - Avoid installing @antoneeo/agentic-sdlc-skill@1.34.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
