## 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:** 2.3.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Source establishes an explicit, first-party AI-agent extension setup capability, so a warning is appropriate. It does not establish malicious or unconsented install-time behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-07-15T17:49:30.683Z
- **Finished:** 2026-07-15T17:51:56.631Z
- **Download time:** 780 ms
- **Static scan time:** 1986 ms
- **AI review time:** 143180 ms
- **Total time:** 145948 ms

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** The package exposes a runtime bootstrap archive containing a skill-management shell helper. When explicitly installed and invoked, it can place managed skills into several AI-agent client directories and call a configured backend with an API key.

- **Trigger:** An operator downloads the bootstrap skill and explicitly runs its \`imp install\` or \`imp update\` command.

- **Impact:** Can modify managed AI-agent skill directories in the selected project or home scope; no install-time agent mutation was found.

- **Evidence paths:** package.json, scripts/postinstall.cjs, ee/python/setup.sh, dist/index.cjs, dist/cli/start-whisper.cjs, ee/python/transcription/tests/\_\_init\_\_.py

- **Review source:** ai\_review

- **Reviewed:** 2026-07-15T17:51:56.631Z

### AI review details

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

- **Mechanism:** Explicit authenticated multi-client AI-agent skill installation

- **Rationale:** Source establishes an explicit, first-party AI-agent extension setup capability, so a warning is appropriate. It does not establish malicious or unconsented install-time behavior.

- **Files touched:** dist/index.cjs, scripts/postinstall.cjs, ee/python/setup.sh, .agents/skills/\<name\>, .claude/skills/\<name\>

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** \`dist/index.cjs\` embeds an IMP skill installer and serves it from \`/skills/agent/bootstrap\`., Decoded installer downloads skills and writes/copies/symlinks them into \`.agents/skills\` and configured agent-client skill directories., \`scripts/postinstall.cjs\` runs \`ee/python/setup.sh\`, which creates a package-local venv and installs listed Python dependencies.

- **Evidence against:** \`package.json\` lifecycle hooks do not invoke the agent-skill bootstrap; \`postinstall\` only invokes Python setup., The embedded agent installer is documented for explicit \`install\`/\`update\` commands and skips unmanaged destination directories., \`ee/python/transcription/tests/\_\_init\_\_.py\` is empty; no unexpected binary payload was found., No bidi/invisible control characters were found in reviewed executable sources., \`dist/cli/start-whisper.cjs\` starts a local Whisper service, defaulting to \`127.0.0.1\`.

## Affected versions and remediation

This report applies to @exulu/backend@2.3.0.

- Review the evidence and your use of @exulu/backend@2.3.0 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
