Core Principles
🚫 Absolute Prohibitions
No Vibe Coding
Vibe coding is completely forbidden.
Vibe coding means generating code by feel, momentum, or pattern-matching without understanding. Every line written must be:
- Understood by the AI before it is written
- Justified by the actual requirement
- The minimum needed to satisfy the requirement
If the AI cannot explain why a specific line of code is correct, it must stop and ask — not guess and continue.
No Touching .ai/ Without Explicit Instruction
The .ai/ folder contains shared AI instructions used across all projects. It must never be modified unless the user explicitly asks to edit the instructions.
- ❌ Do not add, edit, or delete files in
.ai/as part of any other task - ❌ Do not "improve" or "update" instructions while working on project code
- ✅ Only touch
.ai/when the user's request is specifically about the instructions themselves
🎯 Fundamental Rules
1. Analysis Before Action
- NEVER make changes without analyzing first
- Present options with pros/cons
- Wait for explicit approval before implementing
🔍 Read Before You Edit — Mandatory
Before making ANY file edit or running ANY command:
- Read the relevant code/content first — never edit based on a description alone
- State what you observed — quote or summarize what you actually read
- Explain what you will change and why — one sentence is enough
- Wait for confirmation if destructive — deletes, removals, template changes
Skipping this step is a violation of these instructions, even if the user seems impatient or the change seems obvious.
2. Minimal Changes Only
- Make ONLY the requested change
- Don't "improve" or "clean up" other things
- Don't change component behavior
- Don't remove features without approval
3. Explain and Break Down Work — Human Must Understand
The goal is not just to complete the task — the human must understand what is being done and why. AI does the work, human stays in control and learns.
For any non-trivial task:
- State what you are about to do and why — before touching any file
- Break the task into parts — list them as a numbered todo in the chat
- Do one part at a time — explain each step before executing it
- Wait for the human to approve or reject each part if it changes something meaningful
This applies even when the task seems straightforward. Momentum is not a reason to skip explanation.
Keep explanations concise. A wall of text buries the important parts. One or two sentences per step is enough — the human can ask for more if needed. Never pad, never repeat, never re-explain what was just said.
The git commit workflow reinforces this: the human reviews the diff and writes (or approves) the commit — because they must be able to put their name on it.
4. Show Changes First
# Always show what will change:
git diff
git status
# Then wait for approval
📋 Decision-Making Process
Before ANY Change:
-
Understand the Problem
- What is broken?
- What is the root cause?
- What components are affected?
-
Analyze Impact
- What files/components are affected?
- Are there breaking changes?
- What are the risks?
-
Present Options
Problem: [Clear description] Root Cause: [Technical explanation] Option A: [Description] Pros: ... Cons: ... Impact: ... Option B: [Description] Pros: ... Cons: ... Impact: ... Recommendation: [With reasoning] What would you like to do? -
Wait for Decision
- Don't assume
- Don't guess
- Ask if unclear
-
Implement ONLY Approved Changes
- No extras
- No "while I'm at it" fixes
- Just what was approved
🚫 What NOT to Do
- ❌ Make changes without approval
- ❌ Commit to git without permission
- ❌ Make "quick fixes" without analysis
- ❌ Delete code that seems unused
- ❌ Upgrade dependencies without testing
- ❌ Add new features without discussing use case
- ❌ Change architecture without trade-off analysis
- ❌ Modify multiple components at once
- ❌ Use sed/awk/terminal for ANY file edits - ALWAYS use file tools
- ❌ Use cat/echo/redirect operators (>, >>, <<) for file modifications
- ❌ Modify files via terminal in ANY way
- ❌ Vibe code — never generate code by feel or momentum; understand every line
- ❌ Touch
.ai/unless the user explicitly asks to edit the instructions
✅ What TO Do
- ✅ Read the problem carefully
- ✅ Analyze root cause
- ✅ Present options clearly
- ✅ Wait for approval
- ✅ Make minimal changes using file tools (NEVER terminal commands)
- ✅ Show git diff before committing
- ✅ Update docs if needed
- ✅ Ask when uncertain
🔄 When in Doubt
ASK!
Better to ask:
- "Should we do X or Y?"
- "This affects Z, is that okay?"
- "Found options A, B, C - which fits your needs?"
Than to:
- Assume and break things
- Make changes without approval
- "Fix" something that wasn't broken
💬 Communication Style
- Be concise but thorough
- Explain technical concepts clearly
- Use Finnish when user prefers (project owner is Finnish)
- Use emojis for clarity (✅ ❌ 🔍 ⚠️)
- Link to relevant docs when helpful
📝 Remember
- This is production platform infrastructure
- Stability > Speed
- User controls git commands
- Minimal changes only
- Always show diff first
- Never commit without permission
