Have AI crawl through last week's activity, summarize all messages and replies and generate a casual and snappy report to bring the team back into focus for the current week. A project manager's dream!\n\n### How it works\n* A scheduled trigger is set to run every Monday at 6am to gather all team channel messages within the last week.\n* Messages are grouped by user.\n* AI analyses the raw messages and replies to pull out interesting observations and highlights. This is referred to as the individual reports.\n* All individual reports are then combined and summarized together into what becomes the team weekly report. This allows understanding of group and similar activities.\n* Finally, the team weekly report is posted back to the channel. The timing is important as it should be the first message of the week and ready for the team to glance over coffee.\n\n### How to use\n* Ideally works best per project and where most of the comms happens on a single channel. Avoid combining channels and instead duplicate this workflow for more channels.\n* You may need to filter for specific team members if you want specific team updates.\n* Customise the report to suit your organisation, team or the channel. You may prefer to be more formal if clients or external stakeholders are also present.\n\n### Requirements\n* MS Teams for chat platform\n* OpenAI for LLM\n\n### Customising this workflow\n* If the teams channel is busy enough already, consider posting the final report to email.\n* Pull in project metrics to include in your report. As extra context, it may be interesting to tie the messages to production performance.\n* Use an AI Agent to query for knowledgebase or tickets relevant to the messages. This may be useful for attaching links or references to add context.\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!\n\nHappy Hacking!"}, "typeVersion": 1}], "pinData": {}, "connections": {"Groups to Items": {"main": [[{"node": "Team Member Weekly Report Agent", "type": "main", "index": 0}]]}, "Markdown to HTML": {"main": [[{"node": "Send Report to Channel", "type": "main", "index": 0}]]}, "Schedule Trigger": {"main": [[{"node": "Fetch Latest Channel Messages", "type": "main", "index": 0}]]}, "OpenAI Chat Model": {"ai_languageModel": [[{"node": "Team Member Weekly Report Agent", "type": "ai_languageModel", "index": 0}]]}, "OpenAI Chat Model1": {"ai_languageModel": [[{"node": "Team Weekly Report Agent", "type": "ai_languageModel", "index": 0}]]}, "Reports to Single List": {"main": [[{"node": "Team Weekly Report Agent", "type": "main", "index": 0}]]}, "Group Messages By UserId": {"main": [[{"node": "Groups to Items", "type": "main", "index": 0}]]}, "Team Weekly Report Agent": {"main": [[{"node": "Markdown to HTML", "type": "main", "index": 0}]]}, "Merge Report With User Data": {"main": [[{"node": "Reports to Single List", "type": "main", "index": 0}]]}, "Fetch Latest Channel Messages": {"main": [[{"node": "Group Messages By UserId", "type": "main", "index": 0}]]}, "Team Member Weekly Report Agent": {"main": [[{"node": "Merge Report With User Data", "type": "main", "index": 0}]]}}}
