 # 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.
