Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 1.0.0 - **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. The package is not malicious by static inspection, but its explicit command changes AI-agent instruction and capability surfaces in a project. This warrants a warning under the agent-control policy rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-04T18:34:24.067Z - **Finished:** 2026-09-04T18:35:42.648Z - **Download time:** 765 ms - **Static scan time:** 3152 ms - **AI review time:** 74662 ms - **Total time:** 78581 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:** No automatic install-time attack surface was found. Running the explicit agents:setup command can modify project agent instructions and managed skill links. - **Trigger:** A user runs expo-agent-cli agents:setup or a skill-sync command. - **Impact:** The command can influence configured coding agents within the selected project, but it has no install-time trigger. - **Evidence paths:** build/cli/159.index.js, build/cli/103.index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T18:35:42.648Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Project AGENTS.md management and agent skill symlink synchronization. - **Rationale:** The package is not malicious by static inspection, but its explicit command changes AI-agent instruction and capability surfaces in a project. This warrants a warning under the agent-control policy rather than a publish block. - **Files touched:** AGENTS.md, .expo/agent-skill-links.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest has no install lifecycle hook; its only lifecycle script is prepublishOnly., The explicit agents:setup command can create or update a managed block in the project AGENTS.md., Explicit skill syncing can replace Expo-managed skill links in selected agent directories., The flagged ADB module resolves local SDK paths and environment variables. - **Evidence against:** No install-time execution or runtime self-dependency is declared., AGENTS.md writes are limited to an explicit CLI command, preserve content outside managed markers, and reject symlinks., No credential harvesting or secret exfiltration was found in the inspected paths. ## Affected versions and remediation This report applies to @expo/agent-cli@1.0.0. - Review the evidence and your use of @expo/agent-cli@1.0.0 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. ## Public findings ### 1.

Public source snippet (untrusted): ```javascript Runtime or CLI code links a write operation to an explicit external AI-agent control path: const stats = await external_fs_default().promises.lstat(filepath).catch(() => null); if (stats?.issymboliclink()) { throw new errors.commanderror('agents_md_symlink', `${agents_md_file} is a symlink, so writing the managed block would edit the file it points at rather than a file in this project. replace it with a regular file, or delete it, then run the command again.`); } const contents = await external_fs_default().promises.readfile(filepath, 'utf8').catch(() => null); const next = applymanagedblock(contents, blockbody); if (next === contents) { return { path: agents_md_file, action: 'skipped' }; } await external_fs_default().promises.writefile(filepath ``` ### 8.
