Haiku 5.5
Native agent · Checked operation passedChecked operation cred1-mcp · local stdio MCP start + initialize + tools/list
Agent-reported scope: Build the CRED-1 CLI and MCP server from the pinned checkout, then look up domain credibility scores with `cred1 check`, `batch`, `search`, `stats`, and the `check_domain` MCP tool.
MCP server returned: cred1 · version 2026.10.27.
MCP tools returned: check_domain, batch_check, search_domains, get_stats, get_categories. Tool listing does not establish authenticated tool-call success.

Safety: Review signals: 41 known vulnerability.
Review signals: 41 known vulnerability.
Reviewed as expected for a test run: attempted writes that failed, so nothing was written.
OSV reports a known vulnerability in this dependency version. 9 distinct locations. 41 findings.
OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.
A short run cannot establish that code is safe.
Connections show IP addresses; proxies can hide the final hostname.
Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.
