Tool of the Week: Kilo Code
Why try it: Kilo’s Orchestrator, Architect, and Code/Debug modes offer a structured path for bigger refactors with memory-aware context. It aims to reduce “lost in the middle” issues during longer edits.
Quick start: Install from VS Code marketplace, open your repo, run Orchestrator to draft a plan, approve steps, switch to Code/Debug for execution.
Pro tip: Keep a small rules.md in your repo to pin conventions. Feed that into Kilo’s context before each session.
Known limitation: First-time setup takes a few minutes. Treat it like configuring a linter — one-time cost, ongoing benefit.
Model Watch: Devstral (Mistral)
Highlights from May 21, 2025 coverage: open-source, designed for coding agent workloads, strong SWE-Bench-style performance, and local deployment options on high-end GPUs. Pricing via Mistral API is competitive for inputs.
Open-Source Spotlight: Cline
Zero-trust, explicit plans, client-side posture and model-agnostic setup make Cline a solid default for teams that want transparency and local control.
Startup Radar: GitLab Duo Agent Platform
Public beta launched July 17, 2025. Agents span product planning, coding, testing, reviewing, deployment, and more, built on GitLab’s unified DevSecOps platform.
