How I went from inconsistent AI coding to 10x improvement in success rates
The Problem We All Know
// Monday
AI: generates perfect, clean code
Me: „This is amazing!“
// Tuesday
AI: same prompt, produces garbage
Me: „Why does this work sometimes and not others?!“
Sound familiar? After months of this frustration, I dug into why AI development feels so random.
TL;DR: Most AI failures aren’t model failures – they’re context failures. I built a systematic solution.
What I Discovered
The real issue isn’t that AI models are inconsistent. It’s that we’re giving them inconsistent, incomplete context.
Think about onboarding a new developer:
✅ You show them the codebase patterns
✅ You explain the business requirements
✅ You share coding standards and best practices
✅ You provide examples of good/bad implementations
✅ You explain the testing strategy
But with AI, we often just throw a prompt and hope:
❌ „Build me a user auth system“
❌ „Add error handling to this function“
❌ „Write tests for this component“
No wonder results are inconsistent!
Enter Context Engineering
While everyone focuses on prompt engineering (better wording), I focused on context engineering (better information architecture).
Context Engineering = systematically providing AI with comprehensive, structured information needed to complete tasks reliably.
The Framework: 5 Specifications as Code
I built a complete framework with five integrated specifications:
- Specification as Code
What it does: Defines systematic, executable project requirements
Why it matters: Replaces vague requirements with structured, testable specifications
tomlTASK „Implement User Authentication“ {
[manifest] {
target_file = „src/auth/mod.rs“,
task_type = „CodeGeneration“,
failure_strategy = „SequentialDebug“
}
id: implement-auth
depends: [implement-config, setup-database]
description: „JWT-based auth with refresh tokens, rate limiting, and audit logging“
validation_criteria: [„tests_pass“, „security_scan_clean“, „performance_benchmarks_met“]
} - Context Engineering as Code (hats off to Andrej Karpathy and Toni Lutke)
What it does: Dynamically assembles relevant context for each AI task
Why it matters: This is the game-changer – AI gets exactly the information it needs
tomlDEFINE_CONTEXT_PATTERN(rust_actor_implementation) {
context_template = {
instructions = „implement_rust_actor_using_tokio_mpsc“,
examples = [„existing_actor_implementations“, „error_handling_patterns“],
constraints = [„non_blocking_async“, „comprehensive_error_handling“],
validation_criteria = [„cargo_build_succeeds“, „all_tests_pass“, „clippy_clean“]
}
} - Testing as Code
What it does: 15+ advanced testing strategies beyond basic unit tests
Why it matters: AI writes code that’s systematically validated
Property-based testing
Mutation testing
Fuzz testing
Chaos engineering
Security testing
- Documentation as Code
What it does: Living documentation that evolves with code
Why it matters: Knowledge stays current automatically - Coding Best Practices as Code
What it does: Enforceable coding standards (SOLID, DRY, language-specific patterns)
Why it matters: AI follows best practices systematically, not randomly
The Results
After implementing this framework:
10x improvement in AI task success rates
50% reduction in debugging time
Predictable outcomes instead of random results
Systematic quality across all AI-generated code
Technical Implementation
The specifications work together as a pipeline:
Project Requirements (PRD)
↓
Specification as Code (defines tasks)
↓
Context Engineering (assembles context)
↓
AI Actors (execute with rich context)
↓
Quality Validation (testing + practices)
↓
Documentation Generation
Each AI actor receives:
Structured instructions from specifications
Relevant examples from the codebase
Domain knowledge about the business logic
Quality constraints and validation criteria
Available tools and functions
Code Example: Before vs After
Before (Prompt Engineering):
„Create a user service that handles authentication with JWT tokens“
After (Context Engineering):
rust// AI receives comprehensive context:
// – Existing service patterns from codebase
// – JWT implementation examples
// – Error handling standards
// – Testing requirements
// – Security constraints
// – Performance requirements
// – Documentation standards
// Result: Consistent, high-quality implementation every time
Why This Works
Traditional AI development: Inconsistent context → Inconsistent results
Context Engineering approach: Systematic context → Reliable results
The AI isn’t getting smarter – it’s getting better information, structured in a way it can use effectively.
Getting Started
All five specifications are open source:

What’s Your Experience?
Have you struggled with inconsistent AI coding results?
What strategies have you tried to make AI more reliable?
Would you be interested in implementing systematic context engineering?
Community Discussion
I’m looking for:
Feedback on the approach
Contributors to help improve the specifications
Early adopters to share their experiences
Ideas for new context patterns
The Future
We’re moving from „vibe-based AI development“ to systematic AI engineering. The teams that adopt context engineering first will have a massive advantage.
This isn’t just about making AI more reliable (though it does that). It’s about fundamentally changing how we approach AI-assisted development.
