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.
