The through-line was coding agents and the scaffolding they need: a wave of Show HN harnesses for running agents locally, in parallel, and over long-horizon tasks, plus a look at how Dropbox and LinkedIn are operationalizing them in-house.","Underneath the tooling, two quieter threads mattered. On the research side, the conversation turned to evaluation hygiene — why sloppy RL environments quietly degrade models, and a push for fairer deep-research benchmarks. On infrastructure, Google and Databricks both leaned on making inference faster and more reliable rather than bigger.","And a sharp note on trust: as AI-generated pull requests flood open source, maintainers like SerenityOS's Andreas Kling are rethinking whether a substantial patch still signals good faith."],"highlights":["Coding agents dominated: new local-first harnesses (Jeju, Lich), a long-horizon agent (Lazarus), and a Claude Code / Gemini CLI–powered reviewer (Gito v4.1.0).","Dropbox unveiled Nova, an internal platform to orchestrate AI coding agents at engineering scale.","Latent Space argued broken RL environments are actively making models worse — fix the harness before the model.","Google's LiteRT-LM hit up to 2.2x faster local inference via Gemma 4 multi-token prediction.","SerenityOS's Andreas Kling will no longer accept public PRs as AI-generated patches erode the effort-as-good-faith signal."],"article_count":13,"categories":[{"name":"Coding
