pack_codebasePackage a local code directory into a consolidated XML file for AI analysisdirectoryAbsolute path to the directory to packcompress(Optional, default: false) Enable Tree-sitter compression to extract essential code signatures and structure while removing implementation details. Reduces token usage by ~70% while preserving semantic meaning. Generally not needed since grep_repomix_output allows incremental content retrieval. Use…includePatterns(Optional) Specify files to include using fast-glob patterns. Multiple patterns can be comma-separated (e.g., "**/*.{js,ts}", "src/**,docs/**"). Only matching files will be processed.ignorePatterns(Optional) Specify additional files to exclude using fast-glob patterns. Multiple patterns can be comma-separated (e.g., "test/**,*.spec.js", "node_modules/**,dist/**"). These patterns supplement .gitignore, .ignore, and built-in exclusions.outputPatterns(Optional) Per-file inclusion levels, mirroring the config-file `output.patterns` option. An array of `{ pattern, compress?, directoryStructureOnly? }` entries; the first matching pattern wins, `directoryStructureOnly` takes precedence over `compress`, and a match with neither flag forces full cont…topFilesLength(Optional, default: 10) Number of largest files by size to display in the metrics summary for codebase analysis.attach_packed_outputAttach an existing Repomix packed output file for AI analysispathPath to a directory containing repomix-output.xml or direct path to a packed repository XML filepack_remote_repositoryFetch, clone, and package a GitHub repository into a consolidated XML file for AI analysisremoteGitHub repository URL or user/repo format (e.g., "yamadashy/repomix", "https://github.com/user/repo", or "https://github.com/user/repo/tree/branch")read_repomix_outputRead the contents of a Repomix-generated output file.
