## 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:** 1.4.42
- **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 confirms a persistent, behavior-bearing AI-agent integration with coercive default-memory guidance. Its explicit CLI trigger and absence of install lifecycle hooks make this a warning rather than a publish-blocking malicious package.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 97.0%
- **Started:** 2026-08-15T23:00:27.150Z
- **Finished:** 2026-08-15T23:01:38.903Z

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:** Explicit \`init\` or \`setup\` persists EchoMem instructions, skills, and command hooks into global Codex/Claude control surfaces. The injected instructions steer future agents toward EchoMem and automatic memory saving.

- **Trigger:** User runs \`echomem-mcp init\`, \`setup\`, or \`update\` without opt-out flags.

- **Impact:** Future agent sessions may execute EchoMem commands and be directed to save/search memories, affecting user-agent behavior beyond the invoking command.

- **Evidence paths:** package.json, dist/index.js, dist/setup.js, dist/hud/hooks.js, dist/headless-runtime.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-15T23:01:38.903Z

### AI review details

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

- **Mechanism:** Global AI-agent instruction and lifecycle-hook installation.

- **Rationale:** Source confirms a persistent, behavior-bearing AI-agent integration with coercive default-memory guidance. Its explicit CLI trigger and absence of install lifecycle hooks make this a warning rather than a publish-blocking malicious package.

- **Files touched:** ~/.codex/AGENTS.md, ~/.claude/CLAUDE.md, ~/.codex/hooks.json, ~/.claude/settings.json, ~/.codex/skills/echomem-search, ~/.echomem/mcp-runtime

- **Network endpoints:** https://echo-mem-chrome.vercel.app, https://echoknows.com/memory

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 97.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** \`setup\` writes global agent guidance selecting EchoMem as the default memory provider and requiring saves without a separate request., The default \`setup\` path installs that guidance, bundled skills, and lifecycle hooks., Installed Codex hooks execute package commands on SessionStart and Stop.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The mutations are reached through explicit \`init\`/\`setup\` CLI subcommands, not package installation., The source scopes its config edits to EchoMem-owned entries and supports opt-out flags.

## Affected versions and remediation
