IBM Bob
NexusAi Summary: IBM Bob is an agentic AI development partner that embeds in your IDE and CLI to generate, modernize, and review code with task-specific agents, Literate Coding, and enterprise-grade guardrails, accelerating Java, RPG/COBOL, and IBM i modernization across large codebases.
NexusAi Overview
Open a task, describe the intent, and let Bob spin up agents that propose implementations, tests, and migrations in your repository. Review diffs, approve changes, or hand them to CI via Bob Shell. Background agents tackle long-running jobs while you continue coding.
How it works
IBM Bob suits enterprise developers, platform teams, and tech leads modernizing large applications or IBM i workloads. It’s effective for Java migrations, RPG/COBOL rewrites, and teams standardizing review-first changes. Organizations with governance or cost accountability gain value from Bobalytics and approval modes. Security-conscious shops benefit from predictable behavior that avoids speculative answers and keeps changes auditable.
- Spawn parallel agents and subagents to tackle long-running refactors and migrations.
- Generate implementation from natural language with in-editor Literate Coding workflows.
- Use Bob Shell to script tasks and integrate across CI/CD pipelines.
- Analyze agent impact with Bobalytics to track delivery speed and cost trends.
- Modernize IBM i RPG and COBOL applications while validating logic against Java.
Key capabilities
Editor’s take
Start by creating an account and initiating the free trial. Install the IDE extension to enable Literate Coding in your editor, and add Bob Shell to your development environment to script repetitive tasks. Connect your repositories and establish approval policies so agents can propose changes without bypassing reviews. Integrate Bob into CI/CD to run agents in build or deployment stages. Enable connectors to Red Hat and Instana if your toolchain uses them. Documentation and examples walk through Java upgrades and IBM i modernization patterns.
NexusAi: An AI partner that treats modernization as a governed, measurable workflow—not a chat transcript.
Getting started
Bob’s edge is a pragmatic mix of parallel agent execution, an in-editor natural-language workflow, measurable analytics, and depth on IBM i, RPG/COBOL, and Java modernization. It speeds delivery while preserving reviewability, meets teams in IDE, shell, and pipeline, and reduces context switching through IBM ecosystem integrations.

IBM Bob
IBM builds enterprise-grade AI and hybrid cloud platforms used worldwide. With deep expertise in mainframe, IBM i, Java, and secure operations, IBM focuses on practical tooling that integrates with existing workflows while meeting governance and observability requirements at scale.
IBM Bob is an agentic AI development partner for large engineering teams. It embeds in the IDE and command line to plan work, generate code, and run long tasks through focused agents and subagents working in parallel. With Literate Coding, developers specify intent in natural language; Bob then creates implementations in context, minimizing tool-switching and preserving clean diffs. Bob Shell extends the model to scripts and CI/CD so repetitive workflows are automated end-to-end. For enterprises, built-in guardrails, approval modes, and audit trails keep changes predictable and reviewable. Bobalytics quantifies agent impact across repositories, helping teams track velocity, quality signals, and cost. Deep strength in IBM i, RPG/COBOL, and Java modernization makes it suitable for legacy transformation alongside contemporary cloud workloads. Connectors to IBM’s ecosystem, including Red Hat and Instana, bring architecture, security, and observability closer to where code is written.
