Go beyond tactics: mindset and philosophy for agentic developers.
The importance of planning:
"First, create an overall plan. Decide which technologies to use, how the file structure should look, and where each feature should live."
The value of prototyping:
"Create quick prototypes for two approaches and compare which is better."
ykdojo's real experience:
When building a diff viewer, he tried multiple approaches:
In the end, he didn't ship either, but the process reinforced how important planning is.
We live in an era of personalized, custom software.
ykdojo's examples:
You can do it too:
"Build me a CLI tool that automates my daily workflow."
ykdojo's advice:
"If you want something, ask Claude Code to build it. If the project is small enough, you can finish it in 1-2 hours."
ykdojo proposes a "1 billion token rule" instead of the "10,000-hour rule":
"If you want to truly understand AI and build intuition, spend a lot of tokens. Today, that's possible. Opus 4.5 is powerful and affordable enough to run multiple sessions in parallel."
Advice from a world-class rock climber:
"How do I get better at climbing?" "Climb."
The same applies to Claude Code. Using it is the best way to learn.
A virtuous cycle of sharing:
ykdojo learned even more while sharing his tips.

ykdojo submitted feature requests and bug reports, and many were adopted:
/permissions commandykdojo's advice:
"Knowledge sharing isn't one-way. Beyond branding or learning retention, you learn new things during the sharing process."
How to learn:
"Explain Claude Code Hooks in detail"
