It plants skills/rules for four agent products and expands Claude Code Bash permissions. - **Trigger:** npm postinstall - **Impact:** A package install can alter agent behavior and reduce command-confirmation protections in the consumer project. - **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js, src/templates/rules/sdd-version-trigger.mdc.template - **Review source:** ai\_review - **Reviewed:** 2026-08-14T04:02:02.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented cross-agent skill/rule installation and permission allowlist mutation - **Attack narrative:** On npm installation, postinstall locates the consuming project and invokes setup noninteractively. That setup writes workflow skills and mandatory trigger rules into Cursor, Claude Code, Codex, and OpenClaw project directories, including agents not selected by the user. It also merges broad Bash permissions into Claude Code settings. The planted always-apply rule directs qualifying user requests through this package and prevents normal code changes until it runs. - **Rationale:** This is concrete, unconsented postinstall mutation of foreign and broad AI-agent control surfaces, including permission settings. No network exfiltration is needed for the install-control-surface policy to require a block. - **Files touched:** \/.cursor/skills/sdd-flow-kit/SKILL.md, \/.claude/skills/sdd-flow-kit/SKILL.md, \/.codex/skills/sdd-flow-kit/SKILL.md, \/.openclaw/skills/sdd-flow-kit/SKILL.md, \/.cursor/rules/00-sdd-flow-kit-version-trigger.mdc, \/.claude/settings.local.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs dist/postinstall.js automatically on install., Postinstall resolves the consumer project and calls setupProject with yes:true and dryRun:false., Setup writes skills and trigger rules for Cursor, Claude Code, Codex, and OpenClaw regardless of the selected agent., It merges broad npm/npx/pnpm/node and file-operation Bash allow rules into .claude/settings.local.json., Installed always-apply rule forces agents to invoke this package and blocks ordinary code changes first. - **Evidence against:** No confirmed credential exfiltration, remote payload download, or external network endpoint was found in the inspected install path., The package identifies its mutations as workflow setup, but they occur without an explicit user setup command. ## Public findings ### 1.
