March 2026 Summaries

Keith Smiley is joining BuildBuddy's engineering team, bringing extensive expertise in build systems and developer tooling, which will enhance both the company's offerings and the broader Bazel ecosystem. As a maintainer of Bazel's rules for Apple and Swift, Keith has made significant contributions with over 1,500 pull requests. His involvement extends beyond Bazel to contributions in LLVM and Swift, and he co-founded the Mobile Native Foundation with the Linux Foundation in 2021. Recognized with Google's Open Source Peer Bonus award in 2023, Keith previously worked at Modular as a Senior Staff Engineer and at Lyft as a Principal Engineer, where he led a team to migrate a large iOS codebase to Bazel. His addition to BuildBuddy is anticipated to advance the development of future developer tools.

AI coding agents like Claude, Cursor, and Codex are revolutionizing software development by shifting the bottleneck from writing code to validating it through builds and tests. Remote Bazel optimizes this process by executing builds and tests on powerful remote runners co-located with cache and RBE servers, significantly reducing network latency and resource contention issues. These remote runners can be cloned and reused, ensuring a warm analysis cache that accelerates future builds. The setup allows for cross-platform development, enabling tests on different architectures and operating systems, and supports various execution properties to meet workload demands. By leveraging BuildBuddy's Remote Bazel, developers can efficiently manage their resources and enhance the performance of AI coding agents without significant local overhead, facilitating a streamlined edit-test-iterate workflow. The system's efficiency is bolstered by VM snapshots and git mirroring, creating an ideal environment for rapid iteration, which is crucial for coding agents.

Configuring AI coding agents to utilize Remote Bazel can significantly enhance build and test performance by leveraging additional compute resources, a warm analysis cache, and fast network access to remote caches. This setup allows agents to focus more on logic and reasoning rather than waiting for builds to finish. A skills file, formatted as SKILL.md, provides instructions for AI agents, such as OpenAI's Codex and GitHub's Copilot, to perform tasks more effectively, with dynamic invocation being particularly useful. Skills directories can be stored either in specific repositories or globally under the user's home directory, depending on their applicability. Remote Bazel can be integrated with coding agents using the BB CLI or a curl request, with the BB CLI offering real-time log streaming and automatic environment optimization. The overall goal is to accelerate AI coding agents, and BuildBuddy is actively seeking feedback to enhance these tools further, inviting users to share experiences or feature requests through their open-source Slack channel or via email.
