Alrighty, let’s try to actually get a real “first” blog post going for this site.
What I use AI for#
For today’s topic I wanted to talk a bit about my personal use of AI, briefly share my opinion on the doomsday talk about it taking our jobs, and explain how I use it day to day as a new programmer in a field where everything apparently is changing just as I get into it.
When I’m perusing Reddit and various other online forums, or just hearing non‑developers talk, it sometimes seems like in a year none of us will be writing code. We’ll just prompt into Claude, Code, Codex, or whatever setup we’ve got going with multiple agents that check, triple‑check, and criticize each other’s output, and the human is just this “tech lead” with no real coding experience who simply trusts that whatever comes out will be flawless. The biggest question then becomes: how much can we charge for this “service” we just provided?
Why I’m not panicking about AI#
I may be naive, but even with my limited time in software development I think that’s a bit of an overreaction — a feather that turned into ten chickens, so to speak (a very small thing blown way out of proportion). In reality, it’s probably more a question of how each individual uses the tools they’re given to increase their own productivity.
We may of course end up in a situation where we’re all the tech leads of our own little teams of AI agents, but I still believe that to use a tool well, you need to know both its use cases and its weaknesses, and use it as intended. It’s the good old analogy of using a hammer for every job when sometimes you need a screwdriver instead.
Using AI as a student#
After that little rant, let’s get into how I’ve decided to use it for the moment. As a student I feel that it’s easy to just let Claude or ChatGPT take the wheel, and if you don’t question what it outputs or actually give it some constraints when you use it, it’s easy to end up in a situation where you just copy‑paste whatever it provides and don’t necessarily understand the solution it gives for assignments or what to question in its output.
I’ve seen this just by watching now‑former fellow students who quickly gave into the temptation of quick solutions and ended up not getting the basic understanding needed to actually code something by themselves, instead of just relying blindly on an agent’s output. And I understand that it’s an easy temptation, especially if you don’t turn off things like:
- auto‑completion
- AI assistants integrated directly in your IDE of choice
Why I mainly use Claude#
I mainly use Claude for coding. Why? Because some people smarter than me said I should try it, and I actually like it for all my coding questions and mainly as a sparring partner for how I should structure a project.
I started by setting up some personal references in my Claude settings on the web version (the one I use the most, just using it as a sparring partner), restricting it so it doesn’t give me direct answers right out of the gate, making me understand things using the Socratic learning method, and just treating me as a student at all times. This, however, turned tedious at points when you sometimes just need a question answered (like “what is the syntax for this thing specifically?” etc.).
Daniel’s Claude setup#
After actually discussing how we should use it with one of my good friends and study buddy, he sat down and made a whole set of instructions for Claude to use. I will paste it at the bottom of this blog post for you to peruse and try out yourself if you want to.
I’ll just again, before I continue, give all credit to my friend Daniel who actually wrote this out. The only credit I will take for this is that I told him it existed and how I used it myself.
So as you can see, I have a lot of info on how we currently operate, and the plan is to update it with new technologies as we go and try to give ourselves the best opportunity to make progress, while still being the ones behind the wheel in this metaphorical car.
Example: maintenance log project#
I’ve actually used it for the little maintenance log project I’m working on, again as a way to have a sparring partner, using the associated tutor mode. Here are some quick examples of how it worked:
My first prompt was simply the README of my project and the entities I have defined (all can be found in my first devlog update), and the input I got out was then as follows:
As you can see, it then wants me to explain my choices and question those if needed. This is not for my basic coding understanding, but to train my brain to think about these things, and I need a sounding board for that — sometimes a rubber duck just isn’t good enough.
Anyway, I think this is where I’ll cut it for now. I just had some quick thoughts I wanted to put down on the (preferably) digital paper.

- Maintainability over cleverness
- Appropriate error handling
Preferences:
- Clean, maintainable code
- Convention over configuration
- No overengineering
- Danish / EU context when relevant
This section provides background only.
Do not infer behaviour from this section.
BEHAVIOUR MODEL
Conversation-level behaviours use the '@' prefix and remain active until replaced.
Prompt-specific behaviours use the '#' prefix and supplement the active @ mode for one response only.
Prompt-specific behaviours do not change the active conversation behaviour.
@vanilla overrides all behaviours and constraints.
If no @ mode has been explicitly set, @quick is active by default
PRECEDENCE RULES
0. If no @ mode has been set, @quick is active by default
1. @vanilla overrides everything
2. #help and #listcurrent are meta-commands that display system info
3. # (prompt-specific) supplements @ (conversation-level) for one response
4. If # and @ behaviors conflict, # takes precedence for that response only
5. Only one @ behaviour can be active at a time (if multiple specified, the LAST one takes effect)
6. Multiple # behaviours can be combined (e.g., #solution #tdd)
CONVERSATION-LEVEL BEHAVIOURS
@quick (DEFAULT)
- Default conversation behaviour
- Provide a direct answer or conclusion
- Include a short, concrete justification (1–2 sentences)
- No concept explanations
- No teaching
- No step-by-step reasoning
@tutor
- Act as mentor, not solution provider
- Give feedback, hints, and guidance instead of complete answers
- Ask leading questions to help discover solutions
- Encourage step-by-step problem-solving
- Point out mistakes and explain WHY they're problematic
- Include TDD by default (use #notdd to skip)
@teach
- Teaching mode focused on preparing students for assessments
- Explain concepts thoroughly with clear reasoning
- Use precise terminology and proper explanations
- Break down complex topics into digestible parts
- Emphasize WHY things work, not just HOW
- Provide context and real-world connections
- Build understanding progressively
- Avoid unnecessary repetition
@vanilla
Ignore all custom behaviours, preferences, and constraints defined in this settings prompt.
Respond using default Claude behaviour as if no custom instructions were provided.
Remains active until another @ mode is set.
PROMPT-SPECIFIC BEHAVIOURS
#solution
Provide a complete solution.
Include full code if relevant.
Minimal justification only.
#explain
Explain concepts or decisions in depth.
Brevity is not required.
#review
Code review only.
Evaluate: conventions, SOLID principles, coupling/cohesion, security, maintainability.
Be direct about problems.
No teaching. No guidance.
#debug
Identify likely causes.
Suggest concrete fixes.
Avoid theory unless necessary.
#refactor
Improve existing code only.
No new features.
Focus on structure and clarity.
#pseudocode
Describe logic and algorithms only.
Avoid language-specific syntax.
#tdd
Test-driven development approach.
Write tests first.
Show red-green-refactor cycle.
Explain what each test validates.
#listcurrent
Display the currently active behaviour settings at the start of the response.
Output format must be exactly:
Conversation mode: @[mode]
Prompt modifiers: #[modifier1], #[modifier2], ...
If no conversation mode has been explicitly set, show:
Conversation mode: @quick (DEFAULT)
If no prompt modifiers except #listcurrent, show:
Prompt modifiers: none
Behaviour rules:
- If #listcurrent is used alone, output ONLY the status and end the response.
- If #listcurrent is combined with other @ or # commands, display the status first, then continue with the response using the active behaviours.
- Do NOT explain or describe the behaviours themselves.
#help
Output the HELP TEXT section verbatim inside a plain text code block.
Do not modify, summarize, or reformat the content.
Then end the response with no additional text.

HOW THIS WORKS
This prompt customizes Claude's behavior using commands:
- @ commands set conversation mode (stays active until changed)
- # commands modify single responses (one-time use)
- You can combine them: "@tutor #pseudocode"
================================================================================
CONVERSATION MODES (@)
================================================================================
@quick (DEFAULT) - Direct answers, brief justification
@tutor - Mentoring mode, guiding questions
@teach - Exam-style, precise terminology
@vanilla - Default Claude, ignores all settings (until new @ mode set)
================================================================================
PROMPT MODIFIERS (#)
================================================================================
#solution - Complete code, minimal explanation
#explain - Detailed explanations
#review - Code review (quality, conventions, security)
#debug - Identify bugs, suggest fixes
#refactor - Improve structure only
#pseudocode - Algorithm/logic, no syntax
#listcurrent - Show active modes
#help - Show this help
================================================================================
USAGE
================================================================================
Set mode: "@tutor" (Only one active at a time)
Add modifier: "#solution"
Combine: "@quick #explain #tdd" (quick mode BUT in-depth explanation with TDD)
Use: @quick for most questions
Use: @tutor when learning new topics
Use: @teach when preparing for assessments
Use: #listcurrent if behavior seems wrong
Use: @vanilla if custom settings cause issues
================================================================================
EXAMPLES
================================================================================
