THE COACH for Your Agentic Coding Tool
LIGHTMAN gives AI agents the tools and context they need to modernize your legacy code safely, effectively, and reliably!
LIGHTMAN processes large-scale RPG-programs so that AI agents can analyze structures, dependencies, and business logic more reliably, and so that this information is presented to the user in a readable and modern format.
Many RPG programs contain business logic that is decades old. These programs are complex, poorly documented or undocumented, and technically difficult to understand. AI agents can help, but when dealing with large and, above all, old programs, they quickly reach the limits of their context or lose track of important relationships.
- very large RPG programs
- scattered business logic
- missing or outdated documentation
- difficult-to-detect dependencies
- significant effort required for maintenance and modernization
- AI tools lose track of things when dealing with large codebases
LIGHTMAN gives AI agents the tools and context they need to work safely, effectively, and reliably!
LIGHTMAN analyzes and structures large RPG programs and entire libraries WITHOUT AI, ensuring that AI agents not only see individual code fragments but also understand the relevant contexts, which consist entirely of valid data. This results in more precise analyses, better documentation, and more informed modernization decisions.
Identify Code Structure
LIGHTMAN helps break down large RPG programs into logical sections and make their structure easier to understand.
Making business logic visible
Conditions and processes will be easier for AI agents to identify and explain.
Provide context for AI agents
LIGHTMAN organizes information in a way that allows agents to work with a clearer sense of context and less loss of context.
Enable the analysis of large files
Even large RPG files can be examined in a more targeted manner without losing important context.
Support the documentation
The analysis results can be used as a basis for technical documentation, knowledge retention, or handoffs.
Prepare for modernization
LIGHTMAN helps teams better understand risks, dependencies, and relevant areas of code before refactoring or migration.
From RPG code to usable AI context
Typical applications
Provide your agentic coding tool (whether IBM Bob, Claude Code, CoPilot, or similar) with a reliable and secure environment, as well as tools to modernize legacy RPG or COBOL code effectively, securely, and reliably.
Understand more quickly and reliably what a program does and which logic is involved.
With the LIGHTMAN Child tools, your Agentic Coding Tool can analyze existing code much more effectively and accurately and generate clear documentation based on it.
Help new team members understand complex RPG programs more quickly.
Uncover critical expertise from legacy systems before it is lost.
For teams working with legacy RPG or COBOL applications
LIGHTMAN is designed for companies, development teams, and modernization projects that want to better understand, document, or further develop IBM i / RPG code.
- IBM i / AS400-Teams
- IBM z Teams
- RPG and/or COBOL developers
- Legacy modernization projects
- IT Managers and Technical Decision-Makers
- external consulting teams
- Companies with established business logic in RPG or COBOL
Why not just use any AI tool?
General-purpose AI tools can explain individual code snippets. However, when dealing with large RPG files, they often lack the full context. LIGHTMAN was developed specifically for this purpose: it processes large RPG codebases so that AI agents can work with them in a structured and context-aware manner.
- less loss of context with large files
- improved analysis quality
- faster understanding of complex programs
- Support for documentation and modernization
- More targeted use of AI agents in legacy environments
