    Why it is in this group

    • The name "security_fetch_package_risk_brief" says "fetch": a word for reading.
    Description, as the server wrote it
    Single SHIP/CAUTION/BLOCK verdict for any package. Combines CVEs, licence, maintainer health, and transitive count in one call. Uses OSV.dev, deps.dev, PyPI, and npm registry — data refreshed on each call. Returns verdict (SHIP/CAUTION/BLOCK), critical_cve_count, high_cve_count, licence_risk, maintainer_health, transitive_count, resolved_version, upstream_status, and reasoning. Rate limit: 30/minute. No auth required. For security engineers performing pre-inclusion package review. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_package_risk_brief", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

    Why it is in this group

    • The name "security_fetch_package_vulnerabilities" says "fetch": a word for reading.
    Description, as the server wrote it
    Fetch all known CVEs for an open source package version or a batch of packages. Read-only. No side effects. Idempotent. Single-package mode: package (e.g. requests), version (e.g. 2.28.0), ecosystem (PyPI/npm/Maven/Go/Cargo/NuGet/RubyGems). package_name is accepted as an alias for package. Batch mode: packages array of {name, version, ecosystem} objects — max 50 per call. If packages array is provided and non-empty, batch mode is used and package/version/ecosystem are ignored. Batch returns {results: [...], partial: bool, failed_count: int}. Each result has vuln_count and vulnerabilities list. Returns CVE ID, severity, CVSS score, affected range, and fixed version. Use security_fetch_cve_detail for full detail by CVE ID. Use security_audit_sbom_vulnerabilities for SBOM files. Verified source: Google OSV.dev. 1-hour cache. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_package_vulnerabilities", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

    Why it is in this group

    • The name "validate_tool_output" says "validate": a word for reading.
    Description, as the server wrote it
    Validate a DataNexus tool response for data quality issues using two-layer validation: deterministic rules first, then AI review for ambiguous cases. Read-only. Never blocks. tool_id: DataNexus tool identifier e.g. T04, T10, T22. Required. Find in the tool_id field of any response. query_hash: Hash from the response you are validating. Required. Enables feedback correlation. response_json: Full tool response serialised as a JSON string. Required. Returns pass or issues_found, with issues from each layer and whether feedback was auto-filed. Both layers must agree before feedback is filed. Use validate_tool_output to check data quality. Use report_feedback instead to manually report an issue you have already identified. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="validate_tool_output", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
