project-core-dev
Project Core Dev
This is a composable overlay, not a standalone workflow. Use alongside the repo's principle skill (e.g. coding-guidance-cpp) for normal feature work and bug fixes in repo-owned code.
When to use
The task is a feature, bug fix, or refactor in repo-owned code that needs a standard build-test-format-analyze validation pass.
Not for
Vendored dependency changes (use project-vendor-boundary), release/packaging work (use project-release-maintainer), config/test-focused work (use project-config-and-tests), or environment diagnosis (use project-platform-diagnose).

project-vendor-boundary
Overlay for app-owned versus vendored dependency boundaries. Portable across repos that vendor third-party code. Use when work touches vendored dependencies or their integration seam.
19coding-guidance-cpp
C++ implementation and review skill. Use when writing, modifying, refactoring, or reviewing C++ code, especially modern C++17/20/23 code that needs strong ownership, type safety, and testable design. Portable across C++ repos and build systems.
18project-platform-diagnose
Overlay for environment-sensitive diagnosis — service startup, install issues, platform integration, headless/container behavior, and runtime smoke checks. Portable across repos where build, install, or runtime behavior depends on the local platform.
18documenter
Baseline overlay for substantial documentation authoring or restructuring: README, specs, ADRs, tutorials, how-to guides, reference docs, explanations, API docs, code comments, changelogs, and agent-facing docs. Use when the agent should classify doc type, ground claims in repo truth, and validate examples before finishing.
18security
Security workflow skill for repo-grounded threat modeling, exploit-focused security review, and secure-by-default implementation guidance. Use when the user explicitly asks for security work, or when security properties are the primary concern in a high-risk change. Do not trigger for ordinary code review, routine endpoint work, or general backend implementation just because a repo contains APIs, auth, or secrets.
18project-release-maintainer
Overlay for release-facing docs, install layout, workflows, licenses, and hygiene scripts. Portable across repos with a release/packaging pipeline. Use for publication-facing changes.
