The people who understood the system have left.
Every large codebase has the same problems.
New developers take months to become useful.
The documentation describes a system that has changed.
Finding the cause of an incident takes longer than fixing it.
Old code carries vulnerabilities nobody is patching.
This is not a small tax on your engineering team.
Developer time goes to understanding existing code rather than writing it.

Onboard new developers fast.
A new developer asks the agent why a service calls another one, what breaks if a field changes, or where a rule is enforced. Every answer cites the files it came from, so they can check it rather than trust it. Your senior engineers keep their week back.
Documentation the agent maintains for you.
Senpiper Codebase documents what each service does, what it depends on, and how data moves through it. When the code changes, it updates the documentation, so nobody has to remember to.
Find the cause in minutes, not hours.
During an incident or a production issue, the agent follows the failure back through code and finds the path it took, down to the change that caused it.
One path at a time, not one big rewrite.
The agent maps where an old framework or vulnerable dependency reaches across the codebase, then rewrites the affected paths one at a time. Nobody has to approve a rewrite of everything at once.
Banks, ministries and defence suppliers cannot send source code across their own firewall, whatever assurances come with it. This is why they can use it.
