Large Language Models (LLM) & AI Market: Building an AI Harness with Claude Agent SDK
Claire Vo demonstrates how she built a custom AI harness using the Claude Agent SDK to automate Sentry bug triage for her company ChatPRD. The episode explains what an AI harness is, when to build one versus using general-purpose tools, how to encode permissions, and the three core harness components. The live build used a custom terminal UI (Ink) and opinionated adapters for Sentry, Linear, GitHub and Vercel; it relied on Claude Sonnet 4.6 as the runtime model and leveraged Claude Opus and GPT-5.5 (Codex) to help generate the harness code. The post includes architecture notes, code structure, a demo of the harness in action, and links to referenced tooling and models. Publication date: 2026-07-08.
Practical technical how-to showing agent harness patterns and integrations with developer tooling; useful to engineers building agentic automation but not industry-shifting for AdTech/MarTech.
Wichtigste Kernpunkte & Evidenz
- Claire Vo published a tutorial (Jul 08, 2026) showing a custom harness for automating Sentry bug triage built for her company ChatPRD.
- The harness was built using the Claude Agent SDK and a custom terminal UI with the Ink library, plus adapters for Sentry, Linear, GitHub, and Vercel.
- Claude Sonnet 4.6 was used as the model inside the harness; Claire used Claude Opus and GPT-5.5 (Codex) to help generate the harness code.
- The harness automates evidence gathering, root-cause analysis, and follow-up artifact creation to reduce manual bug-triage prompts.
- The article is a technical how-to that includes architecture, code map, file layout, and a live demo of results.
