    "title": "A Bank Built Its Own Coding Agent. It Took Off — Felipe Felisola Caso & Francesco Galletta, Monzo",
    "one_liner": "Monzo's in-house remote coding agent, Agent Chip, now authors over 10% of all merged PRs and runs 1,800+ tasks a day. The speakers say this came from 'lots of little multipliers': existing platform capabilities, an MCP gateway and a sandboxed agent orchestration system, which together made the agent a composable building block.",
    "summary": "Monzo engineers describe Agent Chip, a Slack-native remote coding agent. It went viral internally in January 2026 because you could prompt it just by reacting to a message with its emoji. They argue the 'secret sauce' isn't the model. It is a strong existing platform plus two investments: an MCP gateway that controls agents' access to internal services and knowledge sources, and an orchestration system that runs agents in isolated sandboxes with controlled egress. Because Agent Chip is itself a composable, provider-agnostic building block, teams across the bank keep building new uses on it, including incident investigation, ask-channel responses, data-quality on-call and work by non-engineers.",
    "key_points": [
      "Scale of the problem at Monzo: 3,000+ backend services, around 13,000 data warehouse models, and dozens of ML predictors (credit, financial crime, etc.).",
      "Agent Chip went viral inside Monzo in January 2026: reacting to any Slack message with its emoji turns that message into a prompt. It became an always-available teammate you can @-mention, ask for code reviews, or assign Linear tickets to.",
      "Today Agent Chip authors over 10% of all merged PRs across tech (data, ML, backend, app), runs more than 1,800 tasks per day, and is being adopted by business users for queries and self-serve questions.",
      "'LLMs' is reframed as 'lots of little multipliers': existing platform capabilities (alerting, monitoring, third-party integrations, a staging environment, queuing, easy deployment, database abstractions) are what let it be built quickly.",
      "Before remote agents, Monzo built an MCP gateway for local coding agents. It exposes internal services and knowledge sources deterministically, choosing what agents can see, and handles authentication and authorization per agent.",
      "The orchestration system runs agents in sandbox pods in an isolated namespace, separate from production. An agent image defines the exact tools, CLIs and auth. A proxy allows only chosen egress, such as to code repositories. The innermost 'box inside the box inside the box' is where the non-determinism is allowed to run loose.",
      "Use cases built on top: an incident mode that joins incident channels and investigates logs, traces, services and code while staying 'high signal'; drafting answers in squad-to-squad 'ask channels'; and 'Agent Chip on Call', which triages data-quality alerts reactively and, in a proactive version, flags backend changes that could break data before the next batch run.",
      "The platform is provider-agnostic: the agent box can be swapped for any model chosen per purpose. Non-specialists can get a tested-in-staging draft before involving an engineer for review and deployment, without lowering engineering rigor."
    ],
    "takeaways": [
      "Invest in platform primitives first (staging, deployment, queuing, monitoring, integrations). These are what make a coding agent cheap to build and valuable.",
      "Put internal services and knowledge sources behind an MCP gateway that deterministically chooses what to expose and centralises authentication and authorization for all agents, local and remote.",
      "Run remote agents in isolated sandboxes, separate from production, with a defined agent image and egress allowed only through a proxy, so non-determinism is contained, especially in regulated environments.",
      "Design the agent as a composable, model-agnostic building block with low-friction entry points (Slack emoji, @-mention, Linear assignment) so other teams can build use cases on it.",
      "Keep humans in the loop for review and deployment, and tune agents to be high-signal in sensitive contexts like incidents."
