What problem does it solve? Working with the Jac programming language requires up-to-date knowledge of its compiler, toolchain commands, and evolving syntax, and outdated patterns cause confusing diagnostics. This Skill provides a structured workflow for building, migrating, and validating Jac projects against the installed toolchain. ## Core Features & Use Cases - Project Workflow Orchestration: Routes requests to task-specific bundled Jac skills and enforces a consistent inspect, implement, validate sequence using jac check, jac fmt, and jac test. - Migration Guidance: Maps obsolete Jac syntax to current forms, such as updated lambda signatures and traversal filter syntax, treating compiler diagnostics as authoritative. - Jacpack Handling: Expands and verifies Jacpack templates with jac create, and creates new packs from template directories. - Use Case: A developer inherits a Jac full-stack application that fails to compile after a toolchain upgrade. The Skill walks through inspecting jac.toml, fixing the root compiler diagnostic first, and validating incrementally until jac test passes. ## Quick Start Use the jac-codex-workflow skill to migrate this Jac project to the installed toolchain and verify it with jac check and jac test.
