Guidelines for Trust
Developers define trustworthy code primarily by its correctness (18 participants) and comprehensibility (16 participants). Correct code is precise and error-free, matching requirements. Comprehensible code is easy to understand, transparent, and often uses simple logic and good naming conventions.
Maintainability and similarity to codebase also emerged as significant factors. Other considerations included robustness, minimal code, and the absence of side effects. External factors like positive prior experience and task complexity also influenced trust.
When evaluating AI-suggested code, developers prioritize Comprehensibility most frequently, followed by Correctness. This contrasts with their definitions, where Correctness was top. Factors like Dependency and Safety/Security were considered in assessments but often overlooked in definitions.
Highly correlating with high trust were Common/Generic/Typical Code and Safe and Secure Practices. Conversely, Incomplete Code and Incorrect Code deterministically correlated with distrust, along with Code-Docstring Mismatch and Risk Associated With A Decision.
Out of 142 AI suggestions, 82% were initially accepted, but only 52% ultimately remained in the codebase. This means 48% of initially accepted suggestions were later rejected, changed, or removed.
Reasons for altered trust included:
- Incorrect Correctness assessment: 6 instances where flaws were discovered later.
- Overlooked Minimality: 7 instances where suggestions were correct but introduced unwanted changes.
- Blind Acceptance: 13 instances of accepting code without evaluation, 8 of which later required modification due to incorrectness.
Four validated guidelines emerged to improve developer-AI interactions:
- G1: Double-Sided Clarification: Use structured, precise prompts; AI should ask clarifying questions.
- G2: Prioritize Code Quality Preferences: Define preferences (e.g., comprehensibility, performance) in prompts.
- G3: Evaluate Thoroughly: Treat AI code skeptically, apply thorough unit tests, and request chain-of-thought explanations.
- G4: Value Simplicity: Prioritize minimal, straightforward code; prevent unnecessary features.

Enhance AI-Developer Interactions
| Factor | Defined as Important | Assessed as Important |
|---|---|---|
| Correctness | High | High |
| Comprehensibility | High | Very High |
| Maintainability | Moderate | Low |
| Similarity to Codebase | Moderate | Low |
| Dependency | Low | Moderate |
| Safety/Security | Low | Moderate |
| Notes: Developers define trust differently than how they assess it in practice. Comprehensibility dominates assessment, while factors like Maintainability are often overlooked during real-time evaluation. | ||
Challenges in Real-time Trust Assessment
Our study revealed a significant gap: while developers prioritize correctness and comprehensibility in defining trustworthy code, they lack adequate real-time support to evaluate these characteristics. This often leads them to assess proxy characteristics instead, or to 'blindly' accept suggestions that later require extensive rework.
For instance, 48% of initially accepted AI suggestions were ultimately discarded or heavily modified due to issues like hidden flaws, unwanted changes, or outright incorrectness. This highlights the urgent need for tools that can proactively flag potential issues and support more informed trust decisions on-the-fly, particularly for complex or high-risk code.

Your AI Implementation Roadmap
A phased approach to integrating AI into your development workflow, ensuring sustainable success and enhanced trust.
Phase 01: Assessment & Strategy
Evaluate current development practices, identify key areas for AI integration, and define clear trustworthiness criteria and quality preferences. This phase aligns with our guidelines for Double-Sided Clarification and Prioritizing Code Quality.
Phase 02: Pilot & Integration
Conduct pilot programs with AI code assistants on low-risk projects. Integrate tools for thorough evaluation, including unit testing and code quality checks. Focus on immediate feedback loops to build initial developer trust and adapt prompts.
Phase 03: Scaling & Optimization
Expand AI adoption across teams, refining guidelines and prompt engineering techniques based on early learnings. Introduce mechanisms to detect high-stakes scenarios and encourage simplicity in AI-generated code. Continuously monitor trust dynamics and tool effectiveness.
Phase 04: Continuous Improvement
Establish ongoing training and feedback channels. Explore advanced AI capabilities like explainability and uncertainty markers to further support developer evaluation and reduce over-reliance. Adapt to evolving AI models and maintain high standards for code trustworthiness.
