You have probably used Claude to write a script or two. But most senior IT professionals are using maybe 10% of what it can do for them on a daily basis. This is a practical list of high-value use cases — things you can try today, not theoretical future applications.
1. Writing Technical Documentation You Have Been Putting Off
Paste a script, a runbook, or an architecture diagram description and ask Claude to write the documentation for it. The output is rarely perfect but it is 80% of the way there and takes 30 seconds instead of an hour.
# Prompt:
# "Write an IT runbook for this PowerShell script.
# Include: purpose, prerequisites, step-by-step execution guide,
# expected output, common errors and fixes, and rollback procedure.
# [paste script]"2. Explaining Error Messages You Have Never Seen Before
Paste any cryptic error message — a Windows Event ID, a Bicep deployment failure, an Azure AD error code, a Wireshark trace — and ask what it means and what to check first. Claude knows the context behind most Microsoft-specific error codes and can explain them faster than searching TechNet.
3. Converting Between Formats and Languages
IT environments are full of format conversion tasks that eat time: ARM JSON to Bicep, CSV to PowerShell hash tables, YAML to JSON, regex patterns between flavours, bash scripts to PowerShell. Claude handles all of these accurately and instantly.
# Convert an ARM template to Bicep
# Prompt: "Convert this ARM template to idiomatic Bicep.
# Use symbolic references instead of resourceId() where possible.
# [paste template]"
# Convert a bash onboarding script to PowerShell
# Prompt: "Convert this bash script to PowerShell 7.
# Use native PowerShell idioms, not backtick-escaped bash commands."4. Generating Test Data and Edge Cases
Ask Claude to generate realistic test data for your scripts — a CSV of fake Active Directory users, a JSON payload that mimics a Graph API response, or a list of file paths that will stress-test a cleanup script. It saves the time you would spend either writing test data by hand or running scripts against production to see what they do.
5. Reviewing and Hardening Configurations
Paste a GPO export, a Conditional Access policy JSON, a Firewall rule set, or an NSG definition and ask Claude to identify security risks, compliance gaps, or misconfigurations. It will not catch everything but it will consistently find the obvious issues faster than a manual review.
# Prompt:
# "Review this Conditional Access policy JSON for security gaps.
# Check for: missing exclusions for break-glass accounts, overly broad
# app inclusions, missing location conditions, and any settings that
# could lock out all users. [paste JSON]"6. Writing Better Ticket Descriptions and Post-Mortems
Give Claude bullet points of what happened during an incident and ask it to write a structured post-mortem or a clear ticket description. The quality of incident documentation improves immediately, and it takes two minutes instead of twenty.
7. Learning Unfamiliar Services Quickly
When you need to work with a service you have not used before — Azure Container Apps, Microsoft Entra Verified ID, GitHub Advanced Security — ask Claude to give you the 80/20 explanation: what it does, when to use it, what the gotchas are, and a minimal working example. This is faster than reading an entire learn.microsoft.com module.
8. Building Regex and Complex Filter Expressions
Regex and LDAP/OData filter syntax are two of the most time-consuming things to get right from scratch. Describe what you want to match in plain English and Claude will produce and explain the expression.
# Prompt: "Write a regex that matches Windows file paths including UNC paths
# but excludes paths containing 'temp' or 'tmp' (case-insensitive).
# Explain each part."Summary
The pattern across all of these is the same: you are the domain expert, Claude handles the typing. The time you save on the mechanical parts of IT work is time you can spend on the decisions that actually require your experience.
