AI Colleagues: How monday.com Launched Production AI Agents on Amazon Bedrock

monday.com, which has a ten-year-old codebase, deployed the Sphera AI agent system on Amazon Bedrock to automate development. Agents such as Atlas (role: software engineer) have three "mailboxes": a Slack @mention, a task in monday, and a GitHub PR review request—all events land in a single queue via Amazon SNS and SQS. The infrastructure includes EKS (one pod per agent session), ElastiCache for fast state, EFS for memory and sessions, and S3 for audit logs. Amazon Bedrock provides routing, monitoring, and cross-region recovery. To work with the legacy codebase, five enhancements were introduced: two evaluation metrics (deterministic and LLM-based), file-based memory instead of vector databases, a remote sandbox for testing before review, automated Guardrails checks (tens of thousands of PRs per month, one-fifth rejected), and integration with monday boards for accountability. The Morphex agent is the first fully autonomous one: 19 out of 20 of its PRs are merged without human intervention, and it opens more PRs than most engineers. Statistics: nine out of ten developers use AI tools monthly, and PR throughput per engineer has more than doubled. About 30% of agent PRs pass all Guardrails checks and require no changes, while the rest receive fixes or questions before auto-merge.
