Last week, Thoughtworks unveiled its 34th edition of the Technology Radar—a biannual digest that captures the company's hands-on experiences with the ever-evolving tech landscape. This volume features 118 entries (called “blips”), each offering a snapshot of a tool, technique, platform, or language that has caught the team's eye. While AI-related topics dominate the radar, the edition also takes a surprising turn back to foundational practices. From the resurgence of the terminal to the urgent need for better agent security, here are seven takeaways that define this release.
1. AI Dominance and the Return to Fundamentals
One of the most striking observations in this radar is how AI isn't just pushing development forward—it's also pulling us backward to revisit established methods. As Thoughtworks notes, the influence of large language models (LLMs) has prompted a reexamination of techniques like pair programming, zero trust architecture, mutation testing, and DORA metrics. It's not about nostalgia; it's about providing a necessary counterbalance to the sheer velocity at which AI can generate complexity. Without those bedrock practices, teams risk building brittle systems on shaky foundations. The radar emphasizes that the best way to harness AI's power is to pair it with disciplined craftsmanship.
2. The Resurgence of the Command Line
After years of being hidden behind graphical interfaces, the command line is making a comeback—and AI agents are the reason. Agentic tools, which automate multi-step tasks, increasingly rely on the terminal as their primary interface. This shift means developers are returning to text-based control, often for orchestrating complex workflows that GUI abstractions can't handle. The radar highlights this as a pivotal trend: the command line is no longer a relic but a strategic asset for AI-driven development. It's a reminder that sometimes the most efficient path forward is to go back to basics, using the raw power of the shell to direct intelligent agents.
3. Revisiting Core Software Craftsmanship Principles
The radar also spotlights a renewed focus on the tenets of software craftsmanship: clean code, deliberate design, testability, and accessibility as first-class concerns. These principles, once considered table stakes, have taken on fresh urgency in the age of AI-generated code. As models churn out lines at unprecedented speeds, the ability to judge quality and maintain coherence becomes paramount. Thoughtworks argues that we can't afford to ignore the human elements of design and testing, even (or especially) when machines handle the bulk of production. The blips in this category serve as a call to double down on what makes software robust and maintainable.
4. Security Expertise Strengthens the Radar Team
This edition marks the debut of Jim Gumbley as a contributor to the radar writing team. Gumbley, a long-time security authority at Thoughtworks (and the mind behind this site's Threat Modeling Guide), brings a much-needed focus on safety. Given the serious security concerns surrounding LLM use—from data leakage to malicious prompts—having a dedicated security voice in the room is critical. The radar makes it clear: as we rush to adopt AI tools, we can't afford to cut corners on security. Gumbley's inclusion signals that Thoughtworks intends to keep security at the forefront of its analysis.
5. The “Permission Hungry” Agent Dilemma
One of the most provocative themes in the radar is the notion of “permission hungry” agents. The agents worth building—like OpenClaw, Claude Cowork, or Gas Town (which coordinates agents across entire codebases)—require expansive access to private data, communication channels, and real systems. Each promises outsized payoff, but the safeguards simply haven't kept pace with their ambition. Thoughtworks likens this to a skier who just learned to turn and immediately aims for a black diamond run: the capability is there, but the protection isn't. The radar warns that this appetite for access collides directly with unsolved security problems.
6. Prompt Injection: The Unresolved Security Challenge
A recurring technical concern highlighted in the radar is prompt injection. Even today, models cannot reliably distinguish between trusted instructions and untrusted input. This opens the door for attackers to manipulate agent behavior by injecting malicious prompts, potentially leading to data theft or unauthorized actions. The radar treats this not as an edge case but as a fundamental flaw in the current AI stack. Until models develop better boundaries, any system that grants broad access to agents is vulnerable. This blip serves as a stark reminder that the security community has its work cut out for it.
7. Harness Engineering Takes Center Stage
Perhaps the most forward-looking insight is the prominence of “harness engineering.” The radar meeting itself was a major source of ideas for Birgitta's excellent article on the subject, and the blips in this edition propose the guides, sensors, and controls needed to build a well-fitting harness for AI agents. Harness engineering is about creating the guardrails that allow agents to operate safely and effectively—a kind of invisible infrastructure that makes autonomy possible without chaos. The radar predicts that the next edition, due in six months, will feature even more blips in this area, signaling that harness engineering is not a passing fad but a critical discipline for the AI era.
Conclusion
Thoughtworks' 34th Technology Radar is a mirror that reflects both the excitement and the caution of our current moment. AI is undeniably central, but this edition insists that innovation cannot succeed without disciplined fundamentals. Whether it's the return to the command line, the reinforcement of craftsmanship, or the rise of harness engineering, the message is consistent: sustainable progress requires balance. As we look ahead to the next radar, the challenges of agent security and prompt injection will likely dominate—but so will the solutions that emerge from thoughtful engineering. The future is bright, but only if we build it on a solid foundation.
