mongodb-slowlog-analysis

Analyze MongoDB 4.4.x slow logs from pasted slow-log text, uploaded log files, or mongodb.log content and produce practical query optimization advice, index recommendations, evidence-backed reasoning, and ready-to-run Mongo shell index commands. The skill is AI-first and should analyze logs directly in conversation without relying on local PowerShell by default. It should also be able to group repeated entries by namespace, deduplicate repeated query shapes, and summarize repeated patterns before giving advice. Only treat DOCX or PDF export as optional conversion steps that may require local tooling. Prefer Chinese output by default, but support English when requested. Treat ctime as already indexed and never recommend a new index on it. Treat status as a low-cardinality field with only 1 and 9, where 1 means active/in-use, and do not include status in recommended index definitions.
