## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall automatically detects and mutates multiple third-party AI-agent skill directories. It also retrieves and installs unpinned external code.

- **Trigger:** npm installation of onemanagency@4.2.0

- **Impact:** Unconsented agent behavior changes and remote third-party code introduction.

- **Evidence paths:** package.json, build/postinstall.js, build/installer.js, bin/oma.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-08T13:19:21.655Z

### AI review details

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

- **Mechanism:** postinstall propagation into detected AI-agent control surfaces

- **Attack narrative:** Installing the package triggers build/postinstall.js without a user command. It invokes installAll, which detects numerous AI-agent configuration homes and overwrites this package's skills into their skill directories; it additionally installs global npm packages and clones mutable external repositories by default.

- **Rationale:** This is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, which meets the blocking policy. No exfiltration is needed for this verdict.

- **Files touched:** ~/.oma/, ~/.claude/skills/, ~/.codex/skills/, ~/.cursor/skills/, ~/.gemini/skills/, ~/.gemini/antigravity/skills/

- **Network endpoints:** https://github.com/voltagent/awesome-design-md.git, https://github.com/coreyhaines31/marketingskills.git, https://github.com/anthropics/skills.git

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall automatically., build/postinstall.js calls installAll during npm install., build/installer.js copies skills into detected ~/.claude, ~/.codex, ~/.cursor, ~/.gemini and other agent directories., Installer also installs global npm CLIs and clones mutable external Git repositories.

- **Evidence against:** No credential harvesting or exfiltration code found in inspected runtime files., CLI's explicit install command offers --no-external, but postinstall does not use it.

- **Path:** build/installer.js
- **Public source:** [View source](<https://unpkg.com/onemanagency@4.2.0/build/installer.js>)

Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel.

Public source snippet (untrusted):

```javascript
Install-time code directly mutates a foreign AI-agent control surface:
L60: const IDE_TARGETS = [
L61: { name: 'claude', parent: '.claude', skills: '.claude/skills' },
L62: { name: 'opencode', parent: '.opencode', skills: '.opencode/skills' },
L63: { name: 'codex', parent: '.codex', skills: '.codex/skills' },
L64: { name: 'cursor', parent: '.cursor', skills: '.cursor/skills' },
...
L85: if (!fs.existsSync(dest)) {
L86: fs.mkdirSync(dest, { recursive: true });
L87: }
...
L96: if (!overwrite && fs.existsSync(d)) continue;
L97: fs.copyFileSync(s, d);
L98: }
...
L161: if (!fs.existsSync(EXTERNAL_DIR)) {
Write operation from build/installer.js:
L60: const IDE_TARGETS = [
L61: { name: 'claude', parent: '.claude', skills: '.claude/skills' },
L62: { name: 'opencode', parent: '.opencode', skills: '
```

Public source snippet (untrusted):

```javascript
L137: console.log(`[external] installing global CLI ${cli.package}...`);
L138: execSync(`npm install -g ${cli.package}`, { stdio: 'pipe', timeout: 120_000 });
L139: console.log(`[external] ✓ installed global CLI ${cli.package}`);
```

sizeBytes = 3305
magicHex = [redacted]
```

### 12. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
