Project Vendor Boundary
Read AGENTS.md first. This is a composable overlay, not a standalone workflow.
Use alongside the repo's implementation skill when work touches vendored
dependencies or their integration boundary.
When to use
The change involves vendored third-party code, the boundary between app-owned and vendored code, or dependency integration (subtrees, vendor directories, copied sources).
Not for
App-owned code that does not touch vendor boundaries (use the implementation skill directly), or release/packaging concerns (use project-release-maintainer).
Rules
- prefer app-side integration changes before editing vendored code
- treat vendored code as subtree/vendor content, not normal project code
- keep notices, provenance, and install rules aligned with vendor changes
- avoid unrelated churn inside vendor trees
