ONE_FOR_ALL
An open-source educational skill for OpenAI Codex that uses a layered structure of a main instruction plus reference materials to fix a workflow of understanding first, then planning, then implementation, and finally verification, helping junior engineers complete coding tasks while learning.
Timeline (last 90 days)
Open-source developer Sagar Tarak released ONE_FOR_ALL, a skill for OpenAI Codex, positioned as a mentor for interns and junior engineers and aimed at explaining the reasoning behind engineering decisions.
ONE_FOR_ALL is an open-source skill, already open-sourced on GitHub at the repository path Sagar-Tarak/one-for-all, under the MIT license.
The functional scenarios ONE_FOR_ALL covers include: reading and understanding a codebase, handling tickets, debugging, learning system design, practicing data structures and algorithms, and code review.
The ONE_FOR_ALL workflow is: first understand the problem, then plan the change, then implement it, and finally verify the result.
The ONE_FOR_ALL repository structure includes the main file SKILL.md and five reference documents in the references directory: project-work.md, architecture-and-patterns.md, dsa.md, early-career-engineering.md, and quality-and-delivery.md.
The layered "main instructions + reference material" approach is often called progressive disclosure in practice: the main file keeps only the core workflow and task-routing logic, and detailed knowledge documents are loaded on demand only when the task type matches.
The author poses four questions to be validated: whether the explanations are useful or merely create verbosity, whether the workflow helps in understanding unfamiliar codebases, which development stages need better guidance, and how to encourage learning without slowing down experienced developers.
