Go beyond theory: practical examples of how Claude Code solves real problems and boosts productivity.
Writing code isn't enough. You need to automate the full cycle: write tests, run them, fix failures.
A complete workflow:
"Write a user auth middleware, write the tests too, run the tests, and make sure everything passes."
# Claude:
# 1. Writes middleware code (src/middleware/auth.ts)
# 2. Writes test code (src/middleware/auth.test.ts)
# 3. Runs npm test
# 4. Fixes the code if tests fail
# 5. Repeats until all tests pass
TDD workflow:
"Work in a TDD style: write a failing test first, then write the code to make it pass."
ykdojo's custom workflow components:
/commit analyzes changes and commits/gha analyzes failures/handoff compresses contextList conversations:
$ claude -r
# or
$ c -r
Resume a specific conversation:
$ claude --resume stripe-integration
Search conversation contents (using grep):
# Search for "Stripe" in all conversation files
$ grep -r "Stripe" ~/.claude/conversations/
Claude Code is excellent not only for coding but also for writing technical docs, blog posts, and tutorials.
ykdojo's advice:
"Claude sometimes writes repetitive summaries. Explicitly tell it: 'Don't repeat earlier content in the last paragraph.'"
Claude Code can be a powerful research tool that can replace many Google searches.
ykdojo's real example: saving $10,000
ykdojo avoided a $10,000 subscription by researching with Claude Code and discovering he could build a similar capability himself.
Don't trust AI output blindly.
Method 1: write tests
Method 2: visual review with GitHub Desktop
Method 3: create a draft PR
Method 4: ask Claude to self-verify
| Claim | Verification | Result |
|---|---|---|
| "This function is O(n)" | code analysis | OK |
| "All edge cases handled" | test review | Missing null case |
ykdojo's advice:
"My favorite prompt is: 'Double-check everything and create a table of what is verifiable vs not verifiable.'"
Claude Code excels at automating complex DevOps tasks.
ykdojo built a /gha command to automatically investigate GitHub Actions failures.
ykdojo calls Claude Code a "universal interface to the computer":
ykdojo's philosophy:
"If there's something you want to do on your computer, ask Claude Code first. It's surprising how much it can do."
AI-generated code is fast, but it can produce mistakes just as fast. Tests are your safety net.
ykdojo's advice:
"Some say AI can't test its own work, but in practice it can. Writing tests makes you think about the problem differently."
Claude sometimes writes overly complex code.
A simplification prompt:
"This code is too complex. Explain why you wrote it this way and whether you can make it simpler."
ykdojo's advice:
"It's wrong to say that code written with AI can't be understood. If you ask enough questions, you may understand it even faster."
