## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 9.1.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM treats this as warn-only first-party agent extension lifecycle risk. Default installation does not mutate project, HOME, Codex, or global SKS state, apart from a package-local build stamp. With explicit SKS\_POSTINSTALL\_BOOTSTRAP=1, it can configure a global Codex MCP server and install global skills.

## Security analysis

### Published attack-surface review

- **Summary:** Default installation does not mutate project, HOME, Codex, or global SKS state, apart from a package-local build stamp. With explicit SKS\_POSTINSTALL\_BOOTSTRAP=1, it can configure a global Codex MCP server and install global skills.

- **Trigger:** npm install with SKS\_POSTINSTALL\_BOOTSTRAP=1

- **Impact:** Changes the user's AI-agent extension surface after explicit lifecycle opt-in.

- **Evidence paths:** package.json, dist/cli/install-helpers.js, dist/cli/install-helpers-install-support.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-20T10:17:25.066Z

### AI review details

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

- **Mechanism:** opt-in global Codex MCP and skill setup

- **Rationale:** This is not concrete malicious behavior because external agent mutations require an explicit environment opt-in. It warrants a warning because the opted-in lifecycle flow modifies global Codex capabilities.

- **Files touched:** dist/.sks-build-stamp.json, $HOME/.agents/skills

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** Defines an npm postinstall hook., Opt-in postinstall adds the Context7 MCP server to Codex., Opt-in postinstall installs global agent skills.

- **Evidence against:** Default postinstall returns before external mutations unless SKS\_POSTINSTALL\_BOOTSTRAP=1., Default mutation is limited to restoring a package-local build stamp., The MCP setup clears CODEX\_LB\_API\_KEY from its child-process environment.
