+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+This repository is a Go workspace for `github.com/oaswrap/spec`. Core package files live at the repository root and in `openapi/`, `option/`, `pkg/`, and `internal/`. Router adapters are separate modules under `adapter/<framework>openapi/`, each with its own examples, tests, and `go.mod`. Runnable examples live in `examples/` and adapter `example/` directories. Golden YAML fixtures and expected OpenAPI output live in `testdata/` and adapter `testdata/` directories.
+
+## Build, Test, and Development Commands
+
+- `make install-tools`: installs `golangci-lint`.
+- `make test`: runs core and adapter tests with `go test`.
+- `make test-adapter`: runs only adapter module tests.
+- `make test-update`: regenerates golden files when output changes intentionally.
+- `make testcov` / `make testcov-html`: produces coverage reports in `coverage/`.
+- `make lint`: runs `golangci-lint` for core and adapters.
+- `make tidy`: runs `go mod tidy` across core, adapters, and examples.
+- `make sync`: updates the Go workspace.
+- `make check`: runs sync, tidy, lint, and all tests.
+
+Use `go test ./... -run TestName` for focused core tests, or run the same command inside an adapter module for adapter-specific work.
+
+## Coding Style & Naming Conventions
+
+Use standard Go formatting (`gofmt`) and idiomatic Go naming. Package names are short lowercase names such as `openapi`, `option`, or `parser`. Test files must use the `_test.go` suffix. Adapter directories follow the `<framework>openapi` pattern, for example `fiberopenapi` and `ginopenapi`. Keep public APIs documented when exported names are not self-explanatory.
+
+## Testing Guidelines
+
+Tests use Go's standard `testing` package, with golden-file coverage for generated OpenAPI YAML. Add or update tests for behavior changes, especially changes to route registration, schema reflection, options, or adapter output. When running `make test-update`, review all generated fixture diffs before committing.
+
+## Commit & Pull Request Guidelines
+
+Use Conventional Commits:
+
+```text
+feat: add response header option
+fix: handle empty path group correctly
+docs: clarify WithSecurity usage
+```
+
+Accepted types include `feat`, `fix`, `docs`, `style`, `refactor`, `test`, and `chore`. Keep commits focused. Pull requests should describe what changed, why it changed, affected modules or adapters, related issues, and tests run. Include fixture updates when generated output changes.
+
+## Agent-Specific Instructions
+
+Follow existing patterns before adding abstractions. Changes to core generation may require adapter and golden-file updates. Do not modify release tags, generated coverage reports, or unrelated module files unless the task explicitly requires it.
