## 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:** 1.9.3
- **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. Postinstall mutates the consuming project’s Claude skill directory and may modify its ESLint config. This is a first-party developer-tool setup action, but occurs without an explicit setup command.

## Security analysis

### Published attack-surface review

- **Summary:** Postinstall mutates the consuming project’s Claude skill directory and may modify its ESLint config. This is a first-party developer-tool setup action, but occurs without an explicit setup command.

- **Trigger:** npm install of @impakers/debug

- **Impact:** Persistent AI-agent instructions and lint configuration are added to the consumer project.

- **Evidence paths:** package.json, scripts/setup.mjs, templates/ui-mapping-skill.md, dist/telemetry.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T22:13:06.400Z

### AI review details

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

- **Mechanism:** postinstall project configuration and Claude skill installation

- **Rationale:** Source confirms a guarded, first-party Claude skill setup rather than concrete malware. Per policy, this lifecycle control-surface mutation warrants a warning, not a block.

- **Files touched:** scripts/setup.mjs, templates/ui-mapping-skill.md, consumer/.claude/skills/impakers-ui-mapping/SKILL.md, consumer/eslint.config.mjs, consumer/eslint.config.js, consumer/eslint.config.cjs

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/setup.mjs at postinstall., scripts/setup.mjs writes consumer .claude/skills/impakers-ui-mapping/SKILL.md., It also patches a consumer eslint flat-config and executes node --check., The installed skill gives persistent instructions to Claude agents.

- **Evidence against:** Setup is guarded to consumer project roots and supports IMPAKERS\_DEBUG\_SKIP\_SETUP., Skill updates require its managed marker; user-created files are retained., No install-time network, credential collection, or payload download is present., Runtime telemetry redacts sensitive fields before its documented endpoint.

- **Confidence:** 90.0%
- **Path:** scripts/setup.mjs
- **Public source:** [View source](<https://unpkg.com/@impakers/debug@1.9.3/scripts/setup.mjs>)

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

Public source snippet (untrusted):

```javascript
L7: //
L8: //   1. .claude/skills/impakers-ui-mapping/SKILL.md 설치
L9: //      에이전트가 UI 코드를 짤 때 파일 매핑 규칙을 알고 있게 만든다.
