I made a Slack bot, but jarvis themed😉
This needs changes before we can consider it shipped. Review the Shipwright feedback, make updates, then ship again.

hi there!
i'm rejecting this project for the following reasons:
- please change your commands, as stated before there a lot of other bots with the same command style and name on the slack, making it hard for me and the community to test your bot, as we can't know which command points to your bot specifically. as a suggestion, try appending another word to your commands, such as your name.
for any questions please open a ticket in #ask-the-shipwrights

I have finished my Slack Bot mission which is named Jarvis, and it can now be acessed in: https://slack.com/app_redirect?app=A0BNWE36ME2&team=T0266FRGM
It is live 24/7 for free!

hi there!
i'm rejecting this project for the following reasons:
- please rewrite your readme by hand as it is ai generated.
- your banner is incorrect, it must show your bot in action, with a screenshot of its reply.
- please change your commands, there are a million other jarvis bots on the slack and it's really hard to test yours specifically if I don't know which one it is. preferably, append something additionally to each command.
for any questions please open a ticket in #ask-the-shipwrights

Heyo Lalith,
Awesome project but all of the commands seem to be working, it gives the error "invalid_service" whenever i send a command.
Please Fix and Request Re-Certification!
For any other questions, DM @Flux3tor or create a ticket in Slack—#ask-the-shipwrights.

Fixed Jarvis after my first review — moved the AI to Hack Club AI, found and fixed a hidden tool-schema bug, and got all 105 tests passing.I also repaired the broken GitHub Actions deployment workflow and rewrote the README based on what I actually built and learned.Only the final 24/7 Nest deployment + real #bot-spam demo is left before I resubmit.

Hey there, thanks for submitting your project, but it's not quite ready for voting yet. Here are some changes we would like you to make:
- You seem to have used a lot of AI in your README. Please rewrite it yourself, as we would like to see how you worked on the project!
- Your banner is incorrect. It should be a screenshot of the project in action.
- Your bot's demo link is incorrect currently; it points to the #welcome channel but this is not a channel for testing/using Slack bots. I instead recommend having your bot demo link be somewhere like #bot-spam
- Remember to declare all usages of AI in your project, no matter how minor. Currently, you say you used it for some things. This is not enough of an explanation as to what you used it for. You should aim to be decently specific about which parts you used it for.
Once you have fixed these issues, resubmit, and we will be happy to review it! If you have any questions, feel free to ask in #ask-the-shipwrights

hi, nice slackbot, but your demo doesn't work! please see the video for more info. additionally, you've written your entire README with AI! please rewrite it without using AI as well.

The channel you set for demo link seems to be private... Please set the demo link to a public channel for the bot, thank you!

I built Jarvis, an AI Slack bot for the Hack Club workspace that you can @-mention or DM — it chats back with some personality, remembers the conversation, reacts with emoji, and even has real skills like web search, fetching links you share, checking weather in any city, pulling today’s top Hacker News stories, and setting reminders that post right into the thread, plus a few slash commands like /jarvis-ping and /jarvis-joke. The hardest part was getting the AI working: OpenAI had no credits so I migrated the whole thing to Gemini, which meant figuring out a new key format and an OpenAI-compatible endpoint, and discovering the cheapest model isn’t even available to new accounts — plus wiring the agent’s async tool-calling into Slack’s streaming replies while keeping everything testable, which is why there are 48 unit tests with fake clients, a type-checked codebase, clean lint, and a green CI. I’m proud that it’s genuinely polished rather than a demo — every command is jarvis-prefixed so it never collides with the other bots, it has a proper systemd setup for running 24/7 on Nest, and the whole repo is tidy enough that anyone could run it themselves. To test it: invite @Jarvis to any channel in the Hack Club Slack (or DM it) and ask for weather, top stories, a reminder in a few minutes, or paste a link and ask what’s on it — code’s at github.com/Hustlenix/jarvis if you want to see the internals.
Finally, IG that this project is ready to ship as it is working just fine. But, the problem is that Nest is still pending so i can’t get it to 24/7, and IDK why but the app isnt working so the slash commands are still broken on Slack
Learning before building really helped me do it ASAP. To make this, what I did was — spend my first 20 minutes understanding how Slack bots actually work before writing a single line of code or building it. The pieces turned out to be simpler than I feared: a Slack app created at api.slack.com, Socket Mode (the bot connects over WebSockets, so it needs no public URL or server), and two tokens — a bot token (xoxb-…) and an app-level token (xapp-…). Once that clicked, everything else was just wiring.
I built it in Node.js with Slack’s official Bolt framework. One command, node index.js, and Jarvis connects to the Hack Club workspace. Then I gave it a personality and some skills:
- Talk to it — mention @Jarvis or DM it and it replies with AI: concise, friendly, lightly witty
- It remembers — conversation history per thread, so it can actually follow along
- It reacts — every message gets a themed emoji reaction
- 4 slash commands — /jarvis-help, /jarvis-ping, /jarvis-catfact, /jarvis-joke
- An App Home tab — commands list, online status, and feedback buttons
The build wasn’t smooth the whole way, and the failures taught me more than the wins:
- My OpenAI key had zero credits — first AI reply was a sad 429 You have no credits. I switched to Gemini with a free Google AI Studio key, pointed the SDK at Google’s OpenAI-compatible endpoint, and used gemini-3.1-flash-lite, the cheapest model available to new accounts.
- Command collisions — every Slack bot shares the workspace’s slash-command namespace, so I prefixed everything with jarvis- to keep them unique.
- “The app did not respond” — my commands were registered in code but not in the app’s config on Slack’s side. Updating the manifest at api.slack.com and reinstalling the app fixed it. Classic config-vs-code mismatch.
- Repo hygiene — I renamed the entry file to index.js, deleted template leftovers, and squashed the git history into one clean “Initial commit”.
Staying alive 24/7: I cloned the repo onto Hack Club Nest, wrote a systemd service (restarts on crash and on reboot), and enabled it. Jarvis now stays online even with my laptop closed — plus an optional GitHub Action redeploys it on every push.
Quality check: 28 passing tests, lint and typecheck clean.
Jarvis is live in #bot-spam right now. Say hi — or try /jarvis-joke and watch it bomb on purpose.
Spent the last hour last hour learning about slack bot and now i am training and building it in real life. I googled slack bot and a random guy said that hell tech me it and now I am here
