The emerging skillset of wielding coding agents — Beyang Liu, Sourcegraph / Amp

It's raining coding agents! But while many are saying they're feeling the AGI, others say they're not that useful for serious programming. How much is hype and how much is a skill issue? We'll share empirical observations that help explain the divergence of developer opinion. And we'll cover emergent strategies uncovered by users of Amp, a new coding agent in research preview, that can help you employ agents to complete more complex tasks in production codebases. About Beyang Liu Beyang is the co-founder and CTO of Sourcegraph, the company behind Sourcegraph Code Search and Amp. Beyang started his career working on software for some of the largest banks as an engineer at Palantir, where he brought a background in machine learning and data analysis at Stanford.

While some elite programmers are skeptical, many developers find significant value in AI tools, suggesting a disconnect between top-tier and mainstream experience. Liu frames the discussion by referencing opinions from figures like Jonathan Blow and Eric S. Raymond, highlighting the varied perspectives in the field. [03:01] Paradigm Shift: The most significant mistake developers make is using new agents with old mental models. Liu emphasizes that we are in a "step function transition" in model capabilities, meaning that strategies from even six months ago are already outdated for leveraging the full power of today's agents. The Three Eras of AI Coding Tools [05:06] GPT-3 Era (2022): This era was defined by text completion models. The primary application was "copilot" or "autocomplete," where the AI would suggest the next few lines of code based on the preceding context. [05:2
