January 2026 monthly summary: Focused delivery of two major CLI tooling enhancements centered on spaced-repetition-based DSA problem revision to accelerate learning workflows and improve tooling stability. In gittools-bot/homebrew-core, introduced the Data Structures & Algorithms Problem Revision CLI Tool, enabling users to manage and revisit problems via spaced repetition (corresponding to the 1.2.0 release). In ScoopInstaller/Extras, released LeetSolv CLI Tool v1.2.0 with the same spaced repetition revision approach, including architecture details and auto-update functionality to keep tooling current. No major bugs reported this month; efforts prioritized feature delivery, packaging, and release engineering across repos. Impact: enhanced developer learning workflows, shorter preparation cycles for coding interviews, and improved user experience via automated updates and well-documented releases. Technologies/skills demonstrated: CLI design and UX for problem revision, integration of spaced repetition algorithms, release engineering, Homebrew packaging, auto-update mechanisms, versioning, and cross-repo collaboration.
