-description: Find open Dependabot PRs for the current GitHub repo, compare each PR head to its base branch, replay only the net dependency changes in a fresh worktree and branch, run npm validation, and optionally commit, push, and open a PR. Use when you want to batch or manually replicate active Dependabot updates.

-# Dependabot PR Rollup
-
-## When to use
-
-Use this skill when the user wants to:
-- find all open Dependabot PRs in the current repo
-- reproduce their net effect in one local branch
-- validate the result with the repo's standard npm checks
-- optionally commit, push, and open a PR
-
-## Workflow
-
-1. Inspect the current checkout state, but do not reuse a dirty worktree.
-2. List open Dependabot PRs with `gh pr list --state open --author app/dependabot`.
-3. For each PR, collect the title, base branch, head branch, changed files, and relevant diffs.
-4. Compare each PR head against `origin/<base>` instead of trusting the PR title. Dependabot PRs can already be partially merged, superseded by newer versions, or have no remaining net effect.
-5. Create a new worktree and branch from `origin/<base>`.
-6. Reproduce only the remaining dependency changes in the new worktree.
-   - Inspect `package.json` before editing.
-   - Run `npm ci --ignore-scripts` before applying updates.
-   - Use `npm install ... --ignore-scripts` for direct dependency changes so `package-lock.json` stays in sync.
-7. Run `npm run all`.
-8. If requested, commit the changed source, lockfile, and generated artifacts, then push and open a PR.
-
-## Repo-specific notes
-
-- Use `gh` for GitHub operations.
-- Keep the user's original checkout untouched by working in a separate worktree.
-- In this repo, `npm run all` is the safest validation command because it runs build, check, package, and test.
-- If dependency changes affect bundled output, include the regenerated `dist/` files.
-
-## Report back
-
-Always report:
-- open Dependabot PRs found
-- which PRs required no net changes
-- new branch name
-- new worktree path
-- files changed
-- `npm run all` result
-- if applicable, commit SHA and PR URL

+# 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
+├── download/            # Version resolution and binary downloading
+├── 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 ci --ignore-scripts
+```
+
+**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**: ~5 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__/`
+- Add a test in `.github/workflows/test.yml` if it affects integration
+- 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 ci --ignore-scripts` 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.

-# setup-uv agent notes
-
-This repository is a TypeScript-based GitHub Action for installing `uv` in GitHub Actions workflows. It also supports restoring/saving the `uv` cache and optional managed-Python caching.
-
-- The published action runs the committed bundles in `dist/`, not the TypeScript in `src/`. After any code change, run `npm run package` and commit the resulting `dist/` updates.
-- Standard local validation is:
-  1. `npm ci --ignore-scripts`
-  2. `npm run all`
-- `npm run check` uses Biome (not ESLint/Prettier) and rewrites files in place.
-- User-facing changes are usually multi-file changes. If you add or change inputs, outputs, or behavior, update `action.yml`, the implementation in `src/`, tests in `__tests__/`, relevant docs/README, and then re-package.
-- The easiest areas to regress are version resolution and caching. When touching them, add or update tests for precedence, cache invalidation, and cross-platform path behavior.
-- Workflow edits have extra CI-only checks (`actionlint` and `zizmor`); `npm run all` does not cover them.
-- Source is authored with bundler-friendly TypeScript, but published action artifacts in `dist/` are bundled as CommonJS for maximum GitHub Actions runtime compatibility with `@actions/*` dependencies.
-- Keep these concerns separate when changing module formats:
-  - `src/` and tests may use modern ESM-friendly TypeScript patterns.
-  - `dist/` should prioritize runtime reliability over format purity.
-  - Do not switch published bundles to ESM without validating the actual committed artifacts under the target Node runtime.
-- Before finishing, make sure validation does not leave generated or formatting-only diffs behind.
