+# AGENTS.md - Agent Guidelines for Assimp
+
+This document provides guidelines for AI agents working on the Assimp codebase.
+
+## Project Overview
+
+Assimp (Open Asset Import Library) is a C++ library that loads various 3D file formats into a shared, in-memory format. It supports 40+ import formats and several export formats.
+
+## Build Commands
+
+### Basic Build (CMake + Ninja recommended)
+```bash
+# Configure with CMake
+cmake -G Ninja -DASSIMP_BUILD_TESTS=ON -DASSIMP_WARNINGS_AS_ERRORS=ON -S . -B build
+
+# Build
+cmake --build build
+```
+
+### Key CMake Options
+- `-DASSIMP_BUILD_TESTS=ON` - Build unit tests (default ON)
+- `-DASSIMP_WARNINGS_AS_ERRORS=ON` - Treat warnings as errors (default ON)
+- `-DASSIMP_BUILD_ASSIMP_TOOLS=ON` - Build command-line tools
+- `-DASSIMP_BUILD_SAMPLES=ON` - Build sample applications
+- `-DASSIMP_DOUBLE_PRECISION=ON` - Use double precision for calculations
+- `-DASSIMP_NO_EXPORT=ON` - Disable export functionality
+- `-DBUILD_SHARED_LIBS=OFF` - Build static library
+
+### Running Tests
+
+#### Run All Tests
+```bash
+# Using ctest
+cd build && ctest
+
+# Or run unit directly
+./build/unit
+```
+
+#### Run Single Test
+```bash
+# Using ctest with filter
+cd build && ctest -R "TestName"
+
+# Or run unit with filter
+./build/unit --gtest_filter="TestSuiteName.TestName"
+```
+
+For example:
+```bash
+./build/unit --gtest_filter="utObjImportExport.*"
+./build/unit --gtest_filter="utMaterialSystem.*"
+```
+
+#### Test Directory
+Tests are located in `test/unit/` and use Google Test. Test files are named `ut<Feature>.cpp`.
+
+## Code Style
+
+### Formatting
+- **Use clang-format** before committing. Run: `clang-format -i <file>`
+- The project uses a `.clang-format` file at the root with LLVM-based style
+- Key settings:
+  - Indent width: 4 spaces
+  - Tab width: 4, UseTab: Never
+  - ColumnLimit: 0 (no line length limit)
+  - BreakConstructorInitializers: AfterColon
+  - AccessModifierOffset: -4
+
+### Header File Organization
+```cpp
+// Order of includes (use clang-format to enforce):
+// 1. Module's own header
+// 2. Other assimp headers (assimp/*)
+// 3. External headers (contrib/*)
+// 4. Standard library headers
+// 5. System headers
+
+#include "Common/Importer.h"
+#include <assimp/version.h>
+#include <assimp/config.h>
+#include "../contrib/some_lib/some.h"
+#include <vector>
+#include <string>
+```
+
+### Naming Conventions
+- **Classes/Types**: PascalCase (e.g., `Importer`, `aiScene`)
+- **Functions**: PascalCase (e.g., `ReadFile`, `GetExtension`)
+- **Variables**: camelCase (e.g., `scene`, `importStep`)
+- **Constants**: kCamelCase or UPPER_SNAKE_CASE (e.g., `kMaxVertices`)
+- **Member variables**: Often prefixed with `m_` (e.g., `mScene`)
+- **Static variables**: Often prefixed with `s_`
+
+### File Naming
+- **Header files**: PascalCase (e.g., `Importer.h`, `ScenePrivate.h`)
+- **Source files**: PascalCase (e.g., `Importer.cpp`)
+- **Test files**: Prefixed with `ut` (e.g., `utObjImportExport.cpp`)
+
+### C++ Guidelines
+
+#### Language Standard
+- Minimum: C++17
+- Use modern C++ features (smart pointers, constexpr, etc.)
+
+#### Error Handling
+- Use exceptions for recoverable errors (derived from `std::exception`)
+- Use `ai_assert` for debugging assertions in code
+- Return error codes from C API functions
+
+#### Classes
+- Use `ai_enable_erasing` pattern for optional features
+- Use PImpl idiom for ABI stability where appropriate
+
+#### Memory Management
+- Use smart pointers (`std::unique_ptr`, `std::shared_ptr`)
+- Prefer RAII patterns
+- Document ownership semantics in function comments
+
+### Importers/Exporters
+
+#### Structure
+Each importer typically has:
+1. Header in `code/AssetLib/<Format>/`
+2. Implementation in `code/AssetLib/<Format>/`
+3. Registration in `code/Common/ImporterRegistry.cpp`
+4. Unit tests in `test/unit/ImportExport/`
+
+#### Registration
+```cpp
+void GetImporterInstanceList(std::vector<BaseImporter*>& out);
+// Add to registry
+out.push_back(new MyFormatImporter());
+```
+
+### Post-Processing
+
+- Located in `code/PostProcessing/`
+- Each process inherits from `BaseProcess`
+- Implement `ExecuteOnScene` method
+
+### Documentation
+
+- Use Doxygen-style comments for public APIs
+- Example:
+```cpp
+/// <summary>
+/// Loads a file from disk.
+/// </summary>
+/// <param name="pFile">Path to the file.</param>
+/// <returns>Pointer to the imported scene.</returns>
+aiScene* Importer::ReadFile(const char* pFile);
+```
+
+### Contributing
+
+1. Create a fork of assimp
+2. Create a branch for your feature/fix
+3. Run `clang-format` on modified files
+4. Ensure tests pass
+5. Open a PR against `master` branch
+

+# Asset-Importer-Lib AI Tool Use Policy
+
+## Policy
+
+Assimp's policy is that contributors can use whatever tools they would like to
+craft their contributions, but there must be a **human in the loop**.
+**Contributors must read and review all LLM-generated code or text before they
+ask other project members to review it.** The contributor is always the author
+and is fully accountable for their contributions. Contributors should be
+sufficiently confident that the contribution is high enough quality that asking
+for a review is a good use of scarce maintainer time, and they should be **able
+to answer questions about their work** during review.
+
+We expect that new contributors will be less confident in their contributions,
+and our guidance to them is to **start with small contributions** that they can
+fully understand to build confidence. We aspire to be a welcoming community
+that helps new contributors grow their expertise, but learning involves taking
+small steps, getting feedback, and iterating. Passing maintainer feedback to an
+LLM doesn't help anyone grow, and does not sustain our community.
+
+Contributors are expected to **be transparent and label contributions that
+contain substantial amounts of tool-generated content**. Our policy on
+labelling is intended to facilitate reviews, and not to track which parts of
+Assimp are generated. Contributors should note tool usage in their pull request
+description, commit message, or wherever authorship is normally indicated for
+the work. For instance, use a commit message trailer like Assisted-by: <name of
+code assistant>. This transparency helps the community develop best practices
+and understand the role of these new tools.
+
+This policy includes, but is not limited to, the following kinds of
+contributions:
+
+- Code, usually in the form of a pull request
+- RFCs or design proposals
+- Issues or security vulnerabilities
+- Comments and feedback on pull requests
+
+## Details
+
+To ensure sufficient self review and understanding of the work, it is strongly
+recommended that contributors write PR descriptions themselves (if needed,
+using tools for translation or copy-editing). The description should explain
+the motivation, implementation approach, expected impact, and any open
+questions or uncertainties to the same extent as a contribution made without
+tool assistance.
+
+AI tools must not be used to fix GitHub issues labelled [`good first
+issue`][good-first-issue]. These issues are generally not urgent, and are
+intended to be learning opportunities for new contributors to get familiar with
+the codebase. Whether you are a newcomer or not, fully automating the process
+of fixing this issue squanders the learning opportunity and doesn't add much
+value to the project. **Using AI tools to fix issues labelled as "good first
+issues" is forbidden**.
+
+[good-first-issue]: https://github.com/llvm/llvm-project/issues/?q=is%3Aissue%20state%3Aopen%20label%3A%22good%20first%20issue%22
+
+## Extractive Contributions
+
+The reason for our "human-in-the-loop" contribution policy is that processing
+patches, PRs, RFCs, and comments to Assimp is not free -- it takes a lot of
+maintainer time and energy to review those contributions! Sending the
+unreviewed output of an Assimp to open source project maintainers *extracts* work
+from them in the form of design and code review, so we call this kind of
+contribution an "extractive contribution".
+
+Our **golden rule** is that a contribution should be worth more to the project
+than the time it takes to review it. These ideas are captured by this quote
+from the book [Working in Public][public] by Nadia Eghbal:
+
+[public]: https://press.stripe.com/working-in-public
+
+> \"When attention is being appropriated, producers need to weigh the costs and
+> benefits of the transaction. To assess whether the appropriation of attention
+> is net-positive, it's useful to distinguish between *extractive* and
+> *non-extractive* contributions. Extractive contributions are those where the
+> marginal cost of reviewing and merging that contribution is greater than the
+> marginal benefit to the project's producers. In the case of a code
+> contribution, it might be a pull request that's too complex or unwieldy to
+> review, given the potential upside.\" \-- Nadia Eghbal
+
+Prior to the advent of LLMs, open source project maintainers would often review
+any and all changes sent to the project simply because posting a change for
+review was a sign of interest from a potential long-term contributor. While new
+tools enable more development, it shifts effort from the implementor to the
+reviewer, and our policy exists to ensure that we value and do not squander
+maintainer time.
+
+Reviewing changes from new contributors is part of growing the next generation
+of contributors and sustaining the project. We want the LLVM project to be
+welcoming and open to aspiring compiler engineers who are willing to invest
+time and effort to learn and grow, because growing our contributor base and
+recruiting new maintainers helps sustain the project over the long term. Being
+open to contributions and [liberally granting commit access][commit-access]
+is a big part of how LLVM has grown and successfully been adopted all across
+the industry.  We therefore automatically post a greeting comment to pull
+requests from new contributors and encourage maintainers to spend their time to
+help new contributors learn.
+
+[commit-access]: https://llvm.org/docs/DeveloperPolicy.html#obtaining-commit-access
+
+## Handling Violations
+
+If a maintainer judges that a contribution doesn't comply with this policy,
+they should paste the following response to request changes:
+
+    This PR doesn't appear to comply with our policy on tool-generated content,
+    and requires additional justification for why it is valuable enough to the
+    project for us to review it. Please see our developer policy on
+    AI-generated contributions: http://llvm.org/docs/AIToolPolicy.html
+
+The best ways to make a change less extractive and more valuable are to reduce
+its size or complexity or to increase its usefulness to the community. These
+factors are impossible to weigh objectively, and our project policy leaves this
+determination up to the maintainers of the project, i.e. those who are doing
+the work of sustaining the project.
+
+If or when it becomes clear that a GitHub issue or PR is off-track and not
+moving in the right direction, maintainers should apply the `extractive` label
+to help other reviewers prioritize their review time.
+
+If a contributor fails to make their change meaningfully less extractive,
+maintainers should escalate to the relevant moderation or admin team for the
+space (GitHub, Discourse, Discord, etc) to lock the conversation.
+
+## Copyright
+
+Artificial intelligence systems raise many questions around copyright that have
+yet to be answered. Our policy on AI tools is similar to our copyright policy:
+Contributors are responsible for ensuring that they have the right to
+contribute code under the terms of our license, typically meaning that either
+they, their employer, or their collaborators hold the copyright. Using AI tools
+to regenerate copyrighted material does not remove the copyright, and
+contributors are responsible for ensuring that such material does not appear in
+their contributions. Contributions found to violate this policy will be removed
+just like any other offending contribution.
+
+## Examples
+
+Here are some examples of contributions that demonstrate how to apply
+the principles of this policy:
+
+- [This PR][alive-pr] contains a proof from Alive2, which is a strong signal of
+  value and correctness.
+- This [generated documentation][gsym-docs] was reviewed for correctness by a
+  human before being posted.
+
+[alive-pr]: https://github.com/llvm/llvm-project/pull/142869

-#
-#    IL_LIBRARIES -   the name of the IL library. These include the full path to
-#                     the core DevIL library. This one has to be linked into the
-#                     application.
-#    ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
-#                     library is for filters and effects, not actual loading. It
-#                     doesn't have to be linked if the functionality it provides
-#                     is not used.
-#    ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
-#                     library interfaces with OpenGL. It is not strictly needed
-#                     in applications.
-#    IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
-#    IL_FOUND -       this is set to TRUE if all the above variables were set.
-#                     This will be set to false if ILU or ILUT are not found,
-#                     even if they are not needed. In most systems, if one
-#                     library is found all the others are as well. That's the
