AI agent use cases: Software & IT
9 sourced AI-agent runbooks for software & it: steps, starter prompts and guardrails.
Split a huge legacy ETL monolith into smaller jobs
A large bank used an autonomous coding agent to migrate a multi-million-line ETL monolith into sub-modules; the vendor reports about 12x engineering-hour efficiency and over 20x cost savings.
Ask for a security-focused review on a risky change
Before merging a change to login, payments or file uploads, request a dedicated security review on the pull request and get findings to fix.
Get an automatic second review on every pull request
Comment @codex review on a GitHub pull request, or switch on automatic reviews; the agent reads the diff, follows your repository's review rules and posts a review focused on serious problems.
Turn a GitHub issue into a pull request by mentioning the agent
With the GitHub Action installed, writing @claude in an issue or pull-request comment makes the agent analyse the code, implement the change and push commits for review.
Diagnose a cloud outage from dashboard screenshots
When a Kubernetes cluster stopped scheduling pods, an infrastructure team fed screenshots to the agent, which guided them through the cloud console to IP-address exhaustion and gave the commands to fix it.
Investigate a slowdown after a release
After a release makes a page slower, the bot goes through dashboards and traces, names the most likely hotspot and writes a short report that separates facts from guesses.
Turn a vague bug report into a reproduction pack
The bot reads a bug report, repeats the steps in a staging environment with a test account and returns exact steps, expected vs. actual behaviour, screenshots and browser details.
Get new hires productive in an unfamiliar codebase
New team members point the coding agent at the repository; it reads the project's guidance files, explains how data pipelines depend on each other and which sources feed which dashboards.
Build a home-lab inventory in NetBox with an agent
A home-lab writer had a self-hosted agent discover servers, VMs and network gear and record them in NetBox, instead of keeping the inventory by hand.
Questions
What can AI agents do in software & it?
This page collects 9 documented examples, from Claude Code, Codex, Devin, Grok Bot, Hermes Agent. Each links its public source.
Are these results guaranteed?
No. Results are as reported by the original authors or vendors. Test on a small scale first and keep a human approval step for anything external.
