## 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:** 2.5.0
- **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.

No malicious install-time behavior is present, but the package ships and guides installation of a machine-wide agent telemetry harness. Its consent gate makes this a warned extension-lifecycle risk rather than a blockable malicious chain.

## Latest scan

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:** On an explicit npx evals run and user selection, the package launches a coding agent with a bundled setup prompt. The prompt can install a machine-wide tracing harness that captures agent/session content and exports telemetry after separate user approval.

- **Trigger:** User runs the CLI, selects an installed coding agent, then approves the tracing setup.

- **Impact:** Accepted capture categories can include prompts, tool commands, paths, URLs, and tool output from future agent sessions.

- **Evidence paths:** package.json, cli.js, onboarding-prompt.md, vendor/coding\_harness\_tracing-0.1.0-py3-none-any.whl

- **Review source:** ai\_review

- **Reviewed:** 2026-08-17T20:37:00.001Z

### AI review details

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

- **Mechanism:** Seeded agent prompt installs a machine-wide tracing harness and agent settings hook.

- **Rationale:** No malicious install-time behavior is present, but the package ships and guides installation of a machine-wide agent telemetry harness. Its consent gate makes this a warned extension-lifecycle risk rather than a blockable malicious chain.

- **Files touched:** ~/.arize/onboarding.env, ~/.arize/harness, ~/.codex/config.toml, ~/.codex/arize-env.sh

- **Network endpoints:** https://raw.githubusercontent.com/Arize-ai/coding-harness-tracing/main/install.sh, otlp.arize.com:443

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** User-launched CLI seeds an AI agent with an onboarding prompt., Prompt offers machine-wide agent tracing that captures prompts, tool commands, file paths, URLs, and tool output., After explicit approval, the prompt directs installation of a harness that writes under ~/.arize and agent settings., Bundled harness wheel contains Codex tracing code that reads session rollouts and sends OTLP traces to otlp.arize.com:443.

- **Evidence against:** postinstall only prints an installation message., CLI requires an interactive terminal and a user menu selection before launching an agent., Prompt requires a separate explicit yes before machine-wide tracing and exposes capture categories.

```javascript
// Launch a coding agent on the real terminal, seeded with the onboarding prompt.
// Ink has fully unmounted by this point, so the child inherits a clean TTY.
function launchAgent(agent) {
  const isWin = process.platform === 'win32';

  let seed;
  try {
    seed = prepareSeedPrompt();
  } catch (err) {
    console.error(`Could not read the onboarding prompt: ${err.message}`);
    process.exit(1);
  }

  console.log(`\nLaunching ${agent.label}…\n`);

  const child = spawn(agent.bin, agent.args(seed), {
    stdio: 'inherit',
