## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 18 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 2.16.7
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The manifest has no lifecycle hook, and the inspected credential path uses a caller-provided key or the package’s SpaceCode proxy. The agent-related code reads project command files for local trust-status processing; no unconsented agent configuration change or concrete malicious behavior was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-19T21:21:28.984Z

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 confirmed malicious attack surface was identified in the inspected source. The package provides a CLI and an MCP tool for user-invoked remote coding workflows.

- **Trigger:** A user invokes the CLI or calls the MCP remote execution tool.

- **Impact:** The inspected behavior matches the package’s stated cloud development function; no unconsented credential transfer or agent configuration mutation was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T21:22:33.313Z

### AI review details

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

- **Mechanism:** The CLI configures a caller-provided key or the SpaceCode API proxy; the MCP tool sends the requested repository and prompt to a remote sandbox.

- **Rationale:** The manifest has no lifecycle hook, and the inspected credential path uses a caller-provided key or the package’s SpaceCode proxy. The agent-related code reads project command files for local trust-status processing; no unconsented agent configuration change or concrete malicious behavior was found.

- **Files touched:** package.json, dist/index.js, dist/repl.mjs, dist/mcp/index.js

- **Network endpoints:** https://api.spacecode.app

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for AI clean decision:** package.json exposes two CLI binaries, ships dist/\*\*, and lists its dependencies., The CLI uses a caller-supplied API key directly; otherwise it configures the SpaceCode proxy., The default proxy host is api.spacecode.app, consistent with the package’s SpaceCode service., The CLI skips .claude during one project scan; the REPL reads project command files and passes them to local trust-status logic., The MCP tool dispatches the caller’s repository and prompt to a remote sandbox when invoked.
