Prefilled triggers, instructions and connectors. Review and save.
- SupportAnswer community questionsWhen someone runs /quantus in your community channel, look up the answer in your code and docs and reply with it.
- Bug triageAlert on critical Sentry issuesScore each new Sentry issue, explain what broke in plain words on Slack, and open a pull request with the fix. False alarms stay quiet.
- ScansReliability checkEvery hour, compare error rates, latency and saturation with their usual range, and alert Slack when something drifts.
- ScansReview observabilityEvery week, find code paths behind recent errors that are hard to debug, and open a pull request that adds the missing logs and spans.
- SupportAnswer support questionsWhen someone asks a question in your support channel, read the code and docs, then reply in the thread with an answer and links.
- OnchainInvestigate failed transactionsWhen reverted transactions on your contracts spike, decode the revert reasons, trace them to the code and post a summary.
