SubWorkflows\n[Read more about Execute Workflow Trigger](https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-base.executeworkflowtrigger)\n\nIncorporating Subworkflows into your main workflow is an advanced technique and sometimes necessary if you're working with a lot of nested items or loops.\n\nIn this scenario, we perform quite a few lookups to get the data we need; users, messages and replies, which in template terms would require many loop nodes to string together. However, when you nest loops nodes within loop nodes, item reference becomes difficult to keep track of.\n\nUsing subworkflows, we can break down each loop into a separate execution which handles items and item references in a simpler, linear way. The result is predictable data flow throughout our template.

Have AI crawl through last week's activity, summarize all threads 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* Each message thread are grouped by user and data mined for replies.\n* Combined, an AI analyses the raw messages to pull out interesting observations and highlights.\n* The summarized threads of the user are then combined together and passed to another AI agent to generate a higher level overview of their week. These are referred to as the individual reports.\n* Next, all individual reports are summarized together into a 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* Slack for chat platform\n* Gemini for LLM\n\n### Customising this workflow\n* If the slack 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": {"Filter": {"main": [[{"node": "Simplify Thread Comments", "type": "main", "index": 0}]]}, "Switch": {"main": [[{"node": "Get User", "type": "main", "index": 0}], [{"node": "Split Out1", "type": "main", "index": 0}], [{"node": "Map Reply UserIds", "type": "main", "index": 0}]]}, "Get User": {"main": [[{"node": "Messages to Items", "type": "main", "index": 0}]]}, "Aggregate": {"main": [[{"node": "Get User Info", "type": "main", "index": 0}]]}, "Split Out": {"main": [[{"node": "Map Users to Messages", "type": "main", "index": 0}]]}, "Aggregate1": {"main": [[{"node": "Loop Over Items", "type": "main", "index": 0}]]}, "Aggregate2": {"main": [[]]}, "Aggregate3": {"main": [[{"node": "Aggregate4", "type": "main", "index": 0}]]}, "Aggregate4": {"main": [[]]}, "Get Thread": {"main": [[{"node": "Filter", "type": "main", "index": 0}]]}, "Split Out1": {"main": [[{"node": "Loop Over Items", "type": "main", "index": 0}]]}, "Split Out2": {"main": [[{"node": "Get Reply Users", "type": "main", "index": 0}]]}, "Message Ref": {"main": [[{"node": "Get Thread", "type": "main", "index": 0}]]}, "Reply Users": {"main": [[{"node": "Messages to Items1", "type": "main", "index": 0}]]}, "Monday @ 6am": {"main": [[{"node": "Get Last Week's Messages", "type": "main", "index": 0}]]}, "Group By User": {"main": [[{"node": "Split Out", "type": "main", "index": 0}]]}, "Get Reply Users": {"main": [[{"node": "Aggregate Reply Users", "type": "main", "index": 0}]]}, "Has ReplyUsers?": {"main": [[{"node": "Split Out2", "type": "main", "index": 0}], [{"node": "Reply Users", "type": "main", "index": 0}]]}, "Loop Over Items": {"main": [[{"node": "Aggregate3", "type": "main", "index": 0}], [{"node": "Message Ref", "type": "main", "index": 0}]]}, "Simplify Message": {"main": [[{"node": "Aggregate", "type": "main", "index": 0}]]}, "Aggregate Results": {"main": [[{"node": "Team Member Weekly Report Agent", "type": "main", "index": 0}]]}, "Map Reply UserIds": {"main": [[{"node": "Has ReplyUsers?", "type": "main", "index": 0}]]}, "Messages to Items": {"main": [[{"node": "Simplify Message", "type": "main", "index": 0}]]}, "Summarise Threads": {"main": [[{"node": "Aggregate2", "type": "main", "index": 0}]]}, "Merge with Results": {"main": [[{"node": "Team Weekly Report Agent", "type": "main", "index": 0}]]}, "Messages to Items1": {"main": [[{"node": "Summarise Threads", "type": "main", "index": 0}]]}, "Aggregate Reply Users": {"main": [[{"node": "Reply Users", "type": "main", "index": 0}]]}, "Fetch Message Replies": {"main": [[{"node": "Summarize Message Threads", "type": "main", "index": 0}]]}, "Map Users to Messages": {"main": [[{"node": "Fetch Message Replies", "type": "main", "index": 0}]]}, "Get Last Week's Messages": {"main": [[{"node": "Group By User", "type": "main", "index": 0}]]}, "Google Gemini Chat Model": {"ai_languageModel": [[{"node": "Summarise Threads", "type": "ai_languageModel", "index": 0}]]}, "Simplify Thread Comments": {"main": [[{"node": "Aggregate1", "type": "main", "index": 0}]]}, "Team Weekly Report Agent": {"main": [[{"node": "Post Report in Team Channel", "type": "main", "index": 0}]]}, "Google Gemini Chat Model1": {"ai_languageModel": [[{"node": "Team Member Weekly Report Agent", "type": "ai_languageModel", "index": 0}]]}, "Google Gemini Chat Model2": {"ai_languageModel": [[{"node": "Team Weekly Report Agent", "type": "ai_languageModel", "index": 0}]]}, "Summarize Message Threads": {"main": [[{"node": "Aggregate Results", "type": "main", "index": 0}]]}, "Team Member Weekly Report Agent": {"main": [[{"node": "Merge with Results", "type": "main", "index": 0}]]}, "When Executed by Another Workflow": {"main": [[{"node": "Switch", "type": "main", "index": 0}]]}}}
