Feb 1, 2026

February 2026 monthly summary: Delivered substantive business and technical momentum across three primary repos. Wassette released as v0.4.0 with CLI enhancements and clearer separation of local vs remote commands, updated server components and checksums, and provisioning manifests for reliable deployments. Introduced GH-AW (GitHub Agentic Workflows) to enable AI-powered workflow creation, debugging, and shared component management, including pre-pulled API-proxy support for Claude and Codex engines to strengthen security posture. Orchestrated AWF upgrades across multiple releases (v0.13.7, v0.13.12, v0.19.0) with ARM64 multi-architecture builds and firewall/domain reliability improvements. Hardened browser-based tooling with WASM: in-browser gh-aw WASM compiler, comprehensive wasm golden tests, release asset bundling (gh-aw-wasm tar.gz) and Brotli pre-compression, plus significant editor UX improvements (syntax highlighting, imports support, inline prompts, and robust YAML output handling). Strengthened CI and cross-architecture support on macOS and ARM64 with runner upgrades and targeted fixes, boosting release reliability and developer productivity.

January 2026 — Delivered a Mermaid-based Security Architecture Diagram in the Security Guide for GitHub Agentic Workflows, articulating a defense-in-depth model across multiple layers: agent processes in sandboxes, MCP gateway/servers, skill sandboxes, and the proxy/firewall layers governing traffic flow. The update clarifies network interactions and service boundaries to improve security posture and operator clarity. A refinements tweak clarified that MCP servers and skills can connect to distinct external services, each guarded by its own proxy layer. This work enhances security documentation, accelerates secure deployment decisions, and reduces onboarding friction for engineers and operators.
