network, filesystem, Node.js, Python, Java, npm, pip, git, Docker, SQL and Windows codes), explains the cause in plain English and fills the concrete file, host, port or package from your message into the steps.\n\nMethodology:\n- Every pattern is a regular expression with a specificity score from 1 (generic, e.g. \"permission denied\") to 10 (one exact error code).\n- All matching patterns are ranked by specificity, then by how early in the message they match; the top one is explained, the rest are listed.\n- If you pick a context, patterns from matching categories get +2 specificity when ranking.\n- Concrete values (URL, host, port, path, module, package, status/error code) are extracted from the message and inserted into the steps.\n- No match → generic triage steps; nothing is guessed.", "tags": [ "internet" ], "x-mcp-tool": "error_message_translator", "requestBody": { "required": true, "content": { "application/json": { "schema": { "$ref":
