Erik Seliger (Lead Product Engineer at Sourcegraph) and Robert Lin (Lead Platform Engineer at Sourcegraph) join FINOS Zenith Project Lead Peter Smulovics to break down the mechanics of Agentic Batch Changes. They reveal how implementing a multi-layered agent architecture solves the high economic cost of pure "vibe coding" by combining deterministic scripting pipelines with localized, token-efficient AI coding models.🗽 Catch Us in New York!

Traditional coding assistants immediately blow through millions of context-window tokens trying to execute code changes repo-by-repo. Furthermore, when these blind refactoring attempts trigger continuous integration (CI) failures, the model encounters a non-deterministic loop, spinning out out-of-bounds calculations, custom exceptions, and configuration drift that burns cash without hitting production.🏗️ The Solution: The Multi-Layered Agentic Batch Architecture Sourcegraph delivers a structural framework that decouples project coordination from individual script executions:The Outer Loop Project Manager: Running an orchestration agent governed by immutable system prompts to research, manage repository staging, and continuously audit diff outputs.Deterministic Baseline Integration: Using the planning agent to write efficient, low-cost scripts for programmatic tasks (like straightforward find-and-replace or package manager updates) instead of burning tokens on every file.Inner Loop Containment: Deploying localized coding engines (such as Cody or Cloud Code) strictly inside isolated base Docker images to handle ambiguous, complex code edge cases on demand.⚙️ Why This Matters for Financial EngineeringAutomated CI Hook Blocks: Injecting localized AI hooks directly into failing build logs, empowering inner loop agents to dynamically correct pipeline issues in real time based on compilation feedback.Deep MCP Integration: Setting up customized Model Context Protocol (MCP) layers to bridge context lines, letting inner agents instantly ask the master outer orchestrator for repository-scale search data when hitting technical roadblocks.🌐 More about FINOS: https://www.finos.org/📧 Join our newsletter: https://www.finos.org/sign-up🎙️ Listen to our Open Source in Finance Podcast: https://www.youtube.com/@FINOS/podcastsLinkedIn: https://www.linkedin.com/company/finosfoundation
