-# Copilot Instructions for setup-uv
-
-This document provides essential information for GitHub Copilot coding agents working on the `astral-sh/setup-uv` repository.
-
-## Repository Overview
-
-**setup-uv** is a GitHub Action that sets up the [uv](https://docs.astral.sh/uv/) Python package installer in GitHub Actions workflows. It's a TypeScript-based action that downloads uv binaries, manages caching, handles version resolution, and configures the environment for subsequent workflow steps.
-
-### Key Features
-- Downloads and installs specific uv versions from GitHub releases
-- Supports version resolution from config files (pyproject.toml, uv.toml, .tool-versions)
-- Implements intelligent caching for both uv cache and Python installations
-- Provides cross-platform support (Linux, macOS, Windows, including ARM architectures)
-- Includes problem matchers for Python error reporting
-- Supports environment activation and custom tool directories
-
-## Repository Structure
-
-**Size**: Small-medium repository (~50 source files, ~400 total files including dependencies)
-**Languages**: TypeScript (primary), JavaScript (compiled output), JSON (configuration)
-**Runtime**: Node.js 24 (GitHub Actions runtime)
-**Key Dependencies**: @actions/core, @actions/cache, @actions/tool-cache, @octokit/core
-
-### Core Architecture
-```
-src/
-├── setup-uv.ts          # Main entry point and orchestration
-├── save-cache.ts        # Post-action cache saving logic
-├── update-known-versions.ts  # Maintenance script for version updates
-├── cache/               # Cache management functionality

-├── utils/               # Input parsing, platform detection, configuration
-└── version/             # Version resolution from various file formats
-```
-
-### Key Files and Locations
-- **Action Definition**: `action.yml` - Defines all inputs/outputs and entry points
-- **Main Source**: `src/setup-uv.ts` - Primary action logic
-- **Configuration**: `biome.json` (linting), `tsconfig.json` (TypeScript), `jest.config.js` (testing)
-- **Compiled Output**: `dist/` - Contains compiled Node.js bundles (auto-generated, committed)
-- **Test Fixtures**: `__tests__/fixtures/` - Sample projects for different configuration scenarios
-- **Workflows**: `.github/workflows/test.yml` - Comprehensive CI/CD pipeline
-
-## Build and Development Process
-
-### Prerequisites
-- Node.js 24+ (matches GitHub Actions runtime)
-- npm (included with Node.js)
-
-### Essential Commands (ALWAYS run in this order)
-
-#### 1. Install Dependencies
-```bash
-npm install
-```
-**Timing**: ~20-30 seconds  
-**Note**: Always run this first after cloning or when package.json changes
-
-#### 2. Build TypeScript
-```bash
-npm run build
-```
-**Timing**: ~5-10 seconds  
-**Purpose**: Compiles TypeScript source to JavaScript in `lib/` directory
-
-#### 3. Lint and Format Code
-```bash
-npm run check
-```
-**Timing**: ~2-5 seconds  
-**Tool**: Biome (replaces ESLint/Prettier)  
-**Auto-fixes**: Formatting, import organization, basic linting issues
-
-#### 4. Package for Distribution
-```bash
-npm run package
-```
-**Timing**: ~20-30 seconds  
-**Purpose**: Creates bundled distributions in `dist/` using @vercel/ncc  
-**Critical**: This step MUST be run before committing - the `dist/` files are used by GitHub Actions
-
-#### 5. Run Tests
-```bash
-npm test
-```
-**Timing**: ~10-15 seconds  
-**Framework**: Jest with TypeScript support  
-**Coverage**: Unit tests for version resolution, input parsing, checksum validation
-
-#### 6. Complete Validation (Recommended)
-```bash
-npm run all
-```
-**Timing**: ~60-90 seconds  
-**Purpose**: Runs build → check → package → test in sequence  
-**Use**: Before making pull requests or when unsure about build state
-
-### Important Build Notes
-
-**CRITICAL**: Always run `npm run package` after making code changes. The `dist/` directory contains the compiled bundles that GitHub Actions actually executes. Forgetting this step will cause your changes to have no effect.
-
-**TypeScript Warnings**: You may see ts-jest warnings about "isolatedModules" - these are harmless and don't affect functionality.
-
-**Biome**: This project uses Biome instead of ESLint/Prettier. Run `npm run check` to fix formatting and linting issues automatically.
-
-## Testing Strategy
-
-### Unit Tests
-- **Location**: `__tests__/` directory
-- **Framework**: Jest with ts-jest transformer
-- **Coverage**: Version resolution, input parsing, checksum validation, utility functions
-
-### Integration Tests
-- **Location**: `.github/workflows/test.yml` 
-- **Scope**: Full end-to-end testing across multiple platforms and scenarios
-- **Key Test Categories**:
-  - Version installation (specific, latest, semver ranges)
-  - Cache behavior (setup, restore, invalidation)
-  - Cross-platform compatibility (Ubuntu, macOS, Windows, ARM)
-  - Configuration file parsing (pyproject.toml, uv.toml, requirements.txt)
-  - Error handling and edge cases
-
-### Test Fixtures
-Located in `__tests__/fixtures/`, these provide sample projects with different configurations:
-- `pyproject-toml-project/` - Standard Python project with uv version specification
-- `uv-toml-project/` - Project using uv.toml configuration
-- `requirements-txt-project/` - Legacy requirements.txt format
-- `cache-dir-defined-project/` - Custom cache directory configuration
-
-## Continuous Integration
-
-### GitHub Workflows
-
-#### Primary Test Suite (`.github/workflows/test.yml`)
-- **Triggers**: PRs, pushes to main, manual dispatch
-- **Matrix**: Multiple OS (Ubuntu, macOS, Windows), architecture (x64, ARM), and configuration combinations
-- **Duration**: ~20-30 minutes for full matrix
-- **Key Validations**:
-  - Cross-platform installation and functionality
-  - Cache behavior and performance
-  - Version resolution from various sources
-  - Tool directory configurations
-  - Problem matcher functionality
-
-#### Maintenance Workflows
-- **CodeQL Analysis**: Security scanning on pushes/PRs
-- **Update Known Versions**: Daily job to sync with latest uv releases
-- **Dependabot**: Automated dependency updates
-
-### Pre-commit Validation
-The CI runs these checks that you should run locally:
-1. `npm run all` - Complete build and test suite
-2. ActionLint - GitHub Actions workflow validation
-3. Change detection - Ensures no uncommitted build artifacts
-
-## Key Configuration Files
-
-### Action Configuration (`action.yml`)
-Defines 20+ inputs including version specifications, cache settings, tool directories, and environment options. This file is the authoritative source for understanding available action parameters.
-
-### TypeScript Configuration (`tsconfig.json`)
-- Target: ES2024
-- Module: nodenext (Node.js modules)
-- Strict mode enabled
-- Output directory: `lib/`
-
-### Linting Configuration (`biome.json`)
-- Formatter and linter combined
-- Enforces consistent code style
-- Automatically organizes imports and sorts object keys
-
-## Common Development Patterns
-
-### Making Code Changes
-1. Edit TypeScript source files in `src/`
-2. Run `npm run build` to compile
-3. Run `npm run check` to format and lint
-4. Run `npm run package` to update distribution bundles
-5. Run `npm test` to verify functionality
-6. Commit all changes including `dist/` files
-
-### Adding New Features
-- Follow existing patterns in `src/utils/inputs.ts` for new action inputs
-- Update `action.yml` to declare new inputs/outputs
-- Add corresponding tests in `__tests__/`
-- Update README.md with usage examples
-
-### Cache-Related Changes
-- Cache logic is complex and affects performance significantly
-- Test with multiple cache scenarios (hit, miss, invalidation)
-- Consider impact on both GitHub-hosted and self-hosted runners
-- Validate cache key generation and dependency detection
-
-### Version Resolution Changes
-- Version resolution supports multiple file formats and precedence rules
-- Test with fixtures in `__tests__/fixtures/`
-- Consider backward compatibility with existing projects
-- Validate semver and PEP 440 specification handling
-
-## Troubleshooting
-
-### Build Failures
-- **"Module not found"**: Run `npm install` to ensure dependencies are installed
-- **TypeScript errors**: Check `tsconfig.json` and ensure all imports are valid
-- **Test failures**: Check if test fixtures have been modified or if logic changes broke assumptions
-
-### Action Failures in Workflows
-- **Changes not taking effect**: Ensure `npm run package` was run and `dist/` files committed
-- **Version resolution issues**: Check version specification format and file existence
-- **Cache problems**: Verify cache key generation and dependency glob patterns
-
-### Common Gotchas
-- **Forgetting to package**: Code changes won't work without running `npm run package`
-- **Platform differences**: Windows paths use backslashes, test cross-platform behavior
-- **Cache invalidation**: Cache keys are sensitive to dependency file changes
-- **Tool directory permissions**: Some platforms require specific directory setups
-
-## Trust These Instructions
-
-These instructions are comprehensive and current. Only search for additional information if:
-- You encounter specific error messages not covered here
-- You need to understand implementation details of specific functions
-- The instructions appear outdated (check repository commit history)
-
-For most development tasks, following the build process and development patterns outlined above will be sufficient.

+This action controls where uv stores its cache on the runner's filesystem by setting `UV_CACHE_DIR`.
 It defaults to `setup-uv-cache` in the `TMP` dir, `D:\a\_temp\uv-tool-dir` on Windows and
 `/tmp/setup-uv-cache` on Linux/macOS. You can change the default by specifying the path with the
 `cache-local-path` input.

-> If the environment variable `UV_CACHE_DIR` is already set this action will not override it.
-> If you configured [cache-dir](https://docs.astral.sh/uv/reference/settings/#cache-dir) in your
