+# AGENTS.md
+
+## Purpose
+
+This repository is a reference template for PANiXiDA .NET NuGet packages.
+The goal is to keep package structure, CI, versioning, tests, documentation, and release flow consistent across repositories.
+
+## Repository layout
+
+- `src/` — package source code
+- `tests/` — automated tests
+- `README.md` — package overview and usage examples
+- `Directory.Build.props` — shared build settings
+- `Directory.Packages.props` — centralized package versions
+- `version.json` — Nerdbank.GitVersioning configuration
+- `ci.yml` — CI pipeline
+
+## Technology baseline
+
+- .NET 10
+- Nullable enabled
+- Implicit usings enabled
+- Central package management enabled
+- Microsoft Testing Platform
+- xUnit v3
+- FluentAssertions
+- Nerdbank.GitVersioning
+
+## Coding rules
+
+- Preserve existing naming.
+- Do not introduce expression-bodied method declarations.
+- Prefer explicit, readable code over short clever code.
+- Public APIs must include XML documentation written in English.
+- Avoid breaking public API changes unless explicitly requested.
+- Do not weaken nullability annotations.
+- Do not silently change exception behavior.
+
+## Library design rules
+
+- Keep public API small and intentional.
+- Favor immutability for public models.
+- Validate all public method arguments.
+- Prefer deterministic behavior and stable error messages.
+- Do not add dependencies without a strong reason.
+
+## Tests
+
+- Add or update tests for every meaningful behavior change.
+- Cover happy path, guard clauses, and failure scenarios.
+- Verify public API behavior, not implementation details, unless required.
+- When fixing a bug, add a regression test first.
+- Do not add `using Xunit;` or `using FluentAssertions;` in test files, because they are provided as global usings in the test project.
+- Write `DisplayName` values in English.
+- Structure tests using the Arrange, Act, Assert pattern.
+
+## Documentation
+
+- Update `README.md` when public behavior, public API, package metadata, or development workflow changes.
+- Keep the README structure aligned with the repository standard.
+- Keep installation instructions, target framework, badges, and package information accurate.
+- Keep all examples compilable and aligned with the current API.
+- Ensure usage examples reflect real and recommended library usage.
+- Remove outdated or duplicate documentation when updating existing sections.
+
+## Build and validation
+
+Before considering work complete, run:
+
+- `dotnet restore`
+- `dotnet format`
+- `dotnet build --configuration Release`
+- `dotnet test --configuration Release`
+
+## Packaging and versioning
+
+- Package metadata must stay complete and consistent.
+- README and icon must be included in the package.
+- Changes affecting package contents must be reflected in versioning inputs.
+- Do not change package id, repository url, or license without explicit request.
+
+## Definition of done
+
+A change is done only when:
+
+- code is formatted,
+- code builds,
+- tests pass,
+- relevant tests were added or updated,
+- README was updated if public behavior changed,
+- no unnecessary files or dependencies were introduced.
