Let me provide a complete summary:\n\n## Data Directory Structure for Language Support in Vulnhalla\n\nBased on my thorough exploration, here's the complete pattern for adding a new language to Vulnhalla:\n\n### Directory Structure\n\n```\ndata/\n├── queries/\n│   ├── cpp/                          # C++ language queries\n│   │   ├── issues/                   # Vulnerability detection queries\n│   │   │   ├── Copy function using source size.ql\n│   │   │   ├── qlpack.yml\n│   │   │   └── codeql-pack.lock.yml\n│   │   └── tools/                    # Context extraction queries\n│   │       ├── Classes.ql\n│   │       ├── GlobalVars.ql\n│   │       ├── Macros.ql\n│   │       ├── FunctionTree.ql\n│   │       ├── qlpack.yml\n│   │       └── codeql-pack.lock.yml\n│   └── go/                           # Go language queries\n│       ├── issues/\n│       │   ├── SQL injection.ql\n│       │   ├── Command injection.ql\n│       │   ├── Path traversal.ql\n│       │   ├── qlpack.yml\n│       │   └── codeql-pack.lock.yml\n│       └── tools/\n│           ├── FunctionTree.ql\n│           ├── GlobalVars.ql\n│           ├── Types.ql\n│           ├── qlpack.yml\n│           └── codeql-pack.lock.yml\n└── templates/\n    ├── cpp/                          # LLM prompt templates\n    │   ├── Copy function using source size.template\n    │   ├── general.template\n    │   └── template.template\n    └── go/\n        ├── SQL injection.template\n        ├── Command injection.template\n        ├── Path traversal.template\n        ├── general.template\n        └── template.template\n```\n\n### qlpack.yml Configuration\n\nEach language has two qlpack.yml files (one in issues/, one in tools/):\n\n**For C++ (issues):**\n```yaml\nname: vulnhalla-cpp\nversion: 0.0.0\ndependencies:\n  codeql/cpp-all: \"*\"\n```\n\n**For C++ (tools):**\n```yaml\nname: vulnhalla-cpp\nversion: 0.0.0\ndependencies:\n  codeql/cpp-all: \"*\"\n```\n\n**For Go (issues):**\n```yaml\nname: vulnhalla-go\nversion: 0.0.0\ndependencies:\n  codeql/go-all: \"*\"\n```\n\n**For Go (tools):**\n```yaml\nname: vulnhalla-go-tools\nversion: 0.0.0\ndependencies:\n  codeql/go-all: \"*\"\n```\n\nThe pattern is straightforward: reference the appropriate CodeQL pack (e.g., `codeql/cpp-all`, `codeql/go-all`).\n\n### Query File Types\n\n**Issues queries** (detect vulnerabilities):\n- Location: `data/queries/<LANG>/issues/`\n- Format: `.ql` files with CodeQL syntax\n- Metadata: `@name`, `@description`, `@kind`, `@id`, `@problem.severity`, `@security-severity`, `@precision`, `@tags`\n- Example: `SQL injection.ql` for Go, `Copy function using source size.ql` for C++\n- Language imports: `import go`, `import cpp`\n- Taint tracking: Use language-specific taint tracking modules (e.g., `semmle.go.dataflow.TaintTracking`, `semmle.code.cpp.ir.dataflow.TaintTracking`)\n\n**Tools queries** (extract context for LLM analysis):\n- Location: `data/queries/<LANG>/tools/`\n- Names are standardized across languages:\n  - **FunctionTree.ql** - Extract function call chains and caller information\n  - **GlobalVars.ql** - Extract global/package-level variables\n  - **Classes.ql** (C++ only) - Extract classes, namespaces, user types\n  - **Macros.ql** (C++ only) - Extract C/C++ preprocessor macros\n  - **Types.ql** (Go only) - Extract Go struct and interface types\n- Output: CSV format with columns like `function_name`, `file`, `start_line`, `end_line`, `function_id`, `caller_id` (for FunctionTree)\n\n### Language-Specific Query Differences\n\n**C++ (cpp):**\n- Tools include: FunctionTree, GlobalVars, Classes, Macros\n- Classes.ql extracts namespaces and user-defined types with complex logic for anonymous structs\n- Macros.ql is C/C++ specific for preprocessor directives\n- FunctionTree uses `Function` and `FunctionCall` from cpp AST\n\n**Go (go):**\n- Tools include: FunctionTree, GlobalVars, Types\n- Types.ql extracts struct and interface types (no macro equivalent)\n- FunctionTree uses `DeclaredFunction` and `CallExpr` from go AST\n- Distinguishes between `StructType` and `InterfaceType`\n\n### Template Files\n\n**General template structure** (`template.template`):\n```\n### Issue Overview\nName: {name}\nDescription: {description}\nMessage: {message}\nLocation: {location}\n\n### Hints for Validation\n{hints}\n\n### Code\n{code}\n```\n\n**Query-specific templates** (e.g., `SQL injection.template`):\n- Plain text instructions for the LLM\n- Language/query-specific validation questions\n- Guidance on what to look for in the code analysis\n- Example: `SQL injection.template` asks about parameterized queries, string interpolation, input validation\n\n**General template** (`general.template`):\n- Used as fallback when query-specific template doesn't exist\n- Contains: \"1. Is this a real security issue that you can exploit?\"\n\n### Language Code Mapping\n\nThe codebase uses these language codes:\n- **\"c\"** - Maps to \"cpp\" directory for C/C++ analysis (special case in code)\n- **\"go\"** - Maps directly to \"go\" directory for Go analysis\n\nThis mapping occurs in:\n- `/home/josie/development/personal/Vulnhalla/src/codeql/run_codeql_queries.py` (line 263):\n  ```python\n  queries_subfolder = \"cpp\" if lang == \"c\" else lang\n  ```\n- `/home/josie/development/personal/Vulnhalla/src/vulnhalla.py` (line 295):\n  ```python\n  lang_folder = \"cpp\" if self.lang == \"c\" else self.lang\n  ```\n\n### CLI Integration\n\nLanguages are exposed via `--lang` flag in pipeline.py (line 214):\n```python\nparser.add_argument(\"--lang\", choices=[\"c\", \"go\"], default=\"c\", help=\"Programming language to analyze (default: c)\")\n```\n\nSupported invocations:\n```bash\npoetry run vulnhalla redis/redis                    # Defaults to C/C++\npoetry run vulnhalla redis/redis --lang go          # Go analysis\npoetry run vulnhalla --local /path/to/db --lang go  # Local Go database\n```\n\n### Data Flow in Pipeline\n\n1. **Fetch step** - Uses language to find CodeQL databases on GitHub (filters by language tag)\n2. **Query step** - Compiles and runs all `.ql` files from `data/queries/<LANG>/issues/` and `data/queries/<LANG>/tools/`\n3. **Analysis step** - Reads `FunctionTree.csv`, `GlobalVars.csv`, etc. to build LLM context\n4. **Templating step** - Loads templates from `data/templates/<LANG>/` and formats with query-specific hints\n\n### Key Files to Modify for New Language Support\n\nTo add a new language (e.g., \"rust\"), you would need to create:\n\n1. **Query directories:**\n   - `/home/josie/development/personal/Vulnhalla/data/queries/rust/issues/` - with `.ql` files for vulnerability detection\n   - `/home/josie/development/personal/Vulnhalla/data/queries/rust/tools/` - with FunctionTree.ql, GlobalVars.ql, etc.\n\n2. **qlpack.yml files:** In both issues/ and tools/ with dependency on `codeql/rust-all`\n\n3. **Template directories:**\n   - `/home/josie/development/personal/Vulnhalla/data/templates/rust/` - with issue-specific `.template` files, `general.template`, and `template.template`\n\n4. **Code changes:**\n   - Update pipeline.py choices to include \"rust\" in the `--lang` argument\n   - Update language mapping logic if custom directory naming needed\n\nAll file paths are absolute within the project root."}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":0,"cache_creation_input_tokens":619,"cache_read_input_tokens":42656,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":619},"output_tokens":1,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CY2MfDNMqwEhgR98hqLwh","type":"assistant","uuid":"6d7bb4c9-e7bc-4d97-b5d7-aaa7ad7b74fc","timestamp":"2026-02-11T13:26:00.299Z"}
