# Project Core Dev This is a thin project overlay, not a standalone implementation workflow. Use it with matching implementation guidance only when repository-specific checks or gaps remain unclear. Omit it when another selected skill plus repo context already supplies exact commands and reporting obligations. ## When to use The task is a routine repo-owned change whose completion path is not yet concrete. ## Not for Use `project-config-and-tests`, `project-platform-diagnose`, `project-release-maintainer`, or `project-vendor-boundary` when that specialized concern leads. Do not use this skill to restate a generic validation checklist. ## Completion Workflow 1. Read the applicable repository instructions, README, CI configuration, contributor docs, and presets. Identify authoritative commands and mandatory gates; do not invent a second workflow. 2. Map the touched surface to the narrowest honest repo-defined proof. Do not run broad checks merely because they exist. 3. Execute within the task's authority. Prefer check modes for read-only work; do not install tools, start services, or mutate the environment just to close a checklist. 4. Report exact commands, outcomes, gaps, and the narrowest next command that would close each material gap without implying it passed.
