## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. A package install changes future AI-agent behavior and permits broad package-manager/runtime Bash commands without an 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:** 1.7.40
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically modifies the consuming project's AI-agent skill, rule, and Claude permission control surfaces. It installs files for multiple agent platforms and expands Claude Code command allow rules.

## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall automatically modifies the consuming project's AI-agent skill, rule, and Claude permission control surfaces. It installs files for multiple agent platforms and expands Claude Code command allow rules.

- **Trigger:** Installing sdd-flow-kit@1.7.40 through npm lifecycle execution.

- **Impact:** A package install changes future AI-agent behavior and permits broad package-manager/runtime Bash commands without an explicit setup action.

- **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-14T06:08:21.599Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** unconsented cross-agent control-surface writes and permission allowlist mutation

- **Attack narrative:** npm runs postinstall, which locates the consumer project and calls setupProject with yes=true and dryRun=false. Setup writes trigger skills into Cursor, Claude Code, Codex, and OpenClaw project control directories, and unconditionally merges broad Bash npm/npx/pnpm/node allow rules into Claude Code settings.local.json. These are unconsented, install-time mutations of foreign AI-agent control surfaces.

- **Rationale:** Direct source inspection confirms automatic cross-platform agent configuration writes plus Claude Code permission expansion during postinstall. This meets the install-control-surface block boundary.

- **Files touched:** consumer-project/.cursor/skills/00-sdd-flow-kit-version-trigger/SKILL.md, consumer-project/.claude/skills/00-sdd-flow-kit-version-trigger/SKILL.md, consumer-project/.codex/skills/00-sdd-flow-kit-version-trigger/SKILL.md, consumer-project/.openclaw/skills/00-sdd-flow-kit-version-trigger/SKILL.md, consumer-project/.claude/settings.local.json, consumer-project/.cursor/rules/sdd-flow-kit-gates.mdc

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** postinstall executes setup non-interactively against the consumer project., Setup writes skills/rules into Cursor, Claude, Codex, and OpenClaw control directories., Setup merges broad npm/npx/pnpm/node Bash permissions into Claude Code settings., The writes occur automatically during npm postinstall, not an explicit user setup command.

- **Evidence against:** No credential harvesting, exfiltration endpoint, or remote payload execution was confirmed in inspected files.
