• GitHub Actions CI/CD workflows
• Binary release automation (GoReleaser)
• Homebrew tap setup
• crates.io publishing

Explicitly Out:

• Property testing (future enhancement)
• Benchmarks (future enhancement)
• Extensive unit tests for trivial code (per AGENTS.md test proportionality)

Acceptance Criteria

1. Integration Tests

✅ Implement integration tests (file:tests/integration_test.rs):

Test: Basic Usage (Flow 2)

#[tokio::test]
async fn test_basic_usage() {
    // Setup: Create test project with sample files
    // Execute: ruley with mock LLM responses
    // Verify: Output files created with correct content
}

Test: Dry-Run Mode (Flow 4)

#[tokio::test]
async fn test_dry_run() {
    // Execute: ruley --dry-run
    // Verify: No LLM calls made, preview displayed
}

Test: Configuration Merging (Flow 5)

#[tokio::test]
async fn test_config_precedence() {
    // Setup: Config file, env vars, CLI flags
    // Execute: ruley with all three sources
    // Verify: CLI flags override env vars override config file
}

Test: Multi-Format Output (Flow 6)

#[tokio::test]
async fn test_multi_format() {
    // Execute: ruley --format cursor,claude,copilot
    // Verify: All three formats generated correctly
}

Test: Existing Files - Overwrite (Flow 3)

#[tokio::test]
async fn test_overwrite_with_backup() {
    // Setup: Existing output file
    // Execute: ruley with overwrite choice
    // Verify: Backup created, new file written
}

Test: Repomix File (Flow 10)

#[tokio::test]
async fn test_repomix_input() {
    // Setup: Create repomix file
    // Execute: ruley --repomix-file path/to/file
    // Verify: Rules generated from repomix content
}

Test: Chunking (Large Codebase)

#[tokio::test]
async fn test_chunking() {
    // Setup: Large codebase exceeding context limit
    // Execute: ruley with mock LLM
    // Verify: Chunking triggered, merge call made
}

Test: Error Handling (Flow 7)

#[tokio::test]
async fn test_rate_limit_error() {
    // Setup: Mock LLM to return 429
    // Execute: ruley
    // Verify: Retry attempted, contextual error displayed
}

✅ Use test fixtures (file:tests/fixtures/):

• Sample TypeScript project
• Sample Python project
• Sample repomix files (markdown, XML, JSON)
• Mock LLM responses

✅ Use assert_cmd for CLI testing ✅ Use insta for snapshot testing of outputs (optional, only for critical outputs)

2. Unit Tests

✅ Unit tests for critical functionality (per AGENTS.md test proportionality):

Config merging (file:src/cli/config.rs):

• Test precedence: CLI > env > file
• Test config file discovery
• Test invalid config handling

Token counting (file:src/llm/tokenizer.rs):

• Test tiktoken accuracy for OpenAI
• Test Anthropic tokenizer accuracy

Chunking logic (file:src/llm/chunker.rs):

• Test chunk boundaries
• Test overlap calculation
• Test edge cases (empty codebase, single file)

Compression (file:src/packer/compress.rs):

• Test tree-sitter compression ratio (~70%)
• Test whitespace fallback (~30-40%)
• Test parse error handling

Repomix parsing (file:src/packer/repomix.rs):

• Test markdown format parsing
• Test XML format parsing
• Test JSON format parsing
• Test unparsed fallback

State management (file:src/utils/state.rs):

• Test serialization/deserialization
• Test version migration

Plan

Observations

The ruley project already has a solid foundation with comprehensive CI/CD workflows (file:.github/workflows/ci.yml, file:.github/workflows/release.yml), existing test infrastructure (file:tests/integration_test.rs, file:tests/compression_test.rs, file:tests/repomix_test.rs), and test helpers (file:tests/common/mod.rs). The Cargo.toml has proper metadata. However, several integration tests from the ticket are missing, documentation needs expansion, the docs/ directory doesn't exist, and examples are incomplete stubs.

Approach

The implementation will focus on completing the missing integration tests, expanding documentation, creating the docs/ directory structure, and completing examples with working code. The existing CI/CD workflows already handle binary releases and crates.io publishing, so no GoReleaser configuration is needed (GoReleaser is for Go projects). The approach prioritizes test coverage for critical flows, comprehensive documentation following AGENTS.md standards, and working examples that demonstrate the public API.

Implementation Steps

1. Integration Tests - Add Missing Test Cases

Add the following integration tests to file:tests/integration_test.rs:

Test: Basic Usage (Flow 2)

• Create a new test module basic_usage_tests
• Implement test_basic_usage_with_mock_llm that:
  • Creates a mock TypeScript project using typescript_project_files()
  • Runs ruley CLI with --dry-run to verify scanning works
  • Verifies output shows discovered files and configuration
  • Uses assert_cmd for CLI testing

Test: Multi-Format Output (Flow 6)

• Add test_multi_format_output in a new multi_format_tests module
• Test --format cursor,claude,copilot flag parsing
• Verify dry-run shows all three formats in configuration
• Use parse_dry_run_output helper to validate format list

Test: Existing Files - Overwrite (Flow 3)

• Add test_overwrite_behavior in output_integration module
• Create a temporary output file
• Test behavior when output file exists (requires interactive prompt handling or --no-confirm flag)
• Verify backup creation logic (when implemented)

Test: Chunking (Large Codebase)

• Add test_chunking_large_codebase in a new chunking_tests module
• Create a large mock project that exceeds chunk size
• Use --dry-run with --chunk-size 1000 to verify chunking detection
• Verify output indicates chunking will be triggered

Test: Error Handling (Flow 7)

• Add test_error_handling in a new error_handling_tests module
• Test invalid provider: --provider invalid_provider
• Test missing API key scenario (clear env vars)
• Test invalid config file path
• Verify error messages are clear and actionable

2. Unit Tests - Add Missing Critical Tests

• Test Anthropic tokenizer accuracy
• Test edge cases: empty strings, very long strings, special characters
• Use representative code samples from rust_project_files() and typescript_project_files()

Chunking Logic Tests (create file:tests/chunker_test.rs):

• Test chunk boundaries respect token limits
• Test overlap calculation (default 10% of chunk size)
• Test edge cases: empty codebase, single file, file larger than chunk size
• Use ChunkConfig from file:src/llm/chunker.rs

State Management Tests (if state.rs exists in file:src/utils/state.rs):

• Test serialization/deserialization of state

- **Advanced Usage**: Custom prompts, multiple formats, repomix integration

Create `file:docs/configuration.md`:
- **Configuration File**: Location discovery (user config, git root, current dir, explicit path)
- **Configuration Sections**: Document all TOML sections with examples
- **CLI Flags**: Complete reference of all command-line flags
- **Environment Variables**: List all `RULEY_*` variables and provider API keys
- **Precedence Rules**: Detailed explanation of hierarchical merging
- **Examples**: Common configuration scenarios (multi-provider, custom paths, CI/CD)

Create `file:docs/architecture.md`:
- **Pipeline Architecture**: 10-stage pipeline diagram (Init → Scanning → Compressing → Analyzing → Formatting → Writing → Validating → Finalizing → Reporting → Cleanup → Complete)
- **Module Structure**: Describe cli/, packer/, llm/, generator/, output/, utils/
- **Provider System**: Trait-based LLM provider abstraction (`LLMProvider` trait)
- **Compression System**: Tree-sitter vs whitespace compression, language support
- **Chunking System**: Token counting, chunk boundaries, overlap, merge strategy
- **Cost Tracking**: Token counting, pricing models, cost estimation

### 5. Examples - Complete Working Examples

Update `file:examples/basic_usage.rs`:
- Remove TODO comments
- Import `ruley::MergedConfig` and `ruley::run`
- Create a minimal `MergedConfig` with defaults
- Call `ruley::run(config).await?`
- Add comments explaining each configuration field
- Ensure example compiles with `cargo run --example basic_usage`

Update `file:examples/custom_provider.rs`:
- Show how to configure Ollama provider (when feature is enabled)
- Show how to configure OpenRouter provider (when feature is enabled)
- Demonstrate provider-specific configuration from `ProvidersConfig`
- Add working code that creates `MergedConfig` with custom provider settings
- Ensure example compiles with appropriate feature flags

Create `file:examples/multi_format.rs`:
- Demonstrate generating multiple output formats in one run
- Show how to set `format: vec!["cursor".to_string(), "claude".to_string(), "copilot".to_string()]`
- Show how to set custom output paths per format using `output_paths`

Create `file:examples/repomix_input.rs`:
- Demonstrate using an existing repomix file as input
- Show how to set `repomix_file: Some(PathBuf::from("repo.txt"))`
- Explain when this is useful (pre-packed codebases, CI/CD integration)

### 6. API Documentation - Add Rustdoc Comments

Add comprehensive rustdoc comments to public APIs in `file:src/lib.rs`:
- Document `MergedConfig` struct with field descriptions and examples
- Document `PipelineStage` enum with stage descriptions
- Document `PipelineContext` struct and its methods
- Document `run()` function with usage example
- Document `init_logging()` function

Add rustdoc comments to public APIs in modules:
- `file:src/cli/config.rs`: Document config structures and merging logic
- `file:src/llm/tokenizer.rs`: Document `Tokenizer` trait and implementations
- `file:src/llm/chunker.rs`: Document `ChunkConfig` and chunking functions
- `file:src/packer/compress.rs`: Document `Compressor` trait and compression methods
- `file:src/packer/repomix.rs`: Document `parse_repomix()` and format detection
- `file:src/output/mod.rs`: Document output formatter traits and implementations

### 7. CI/CD - Verify Workflows

Review `file:.github/workflows/ci.yml`:
- Verify all test jobs run: quality, test (matrix), features, msrv
- Ensure clippy runs with `--all-features` and `-D warnings`
- Ensure tests run with `--all-features`
- Verify caching is configured for optimal performance

Review `file:.github/workflows/release.yml`:
- Verify multi-platform builds (Linux x86_64/aarch64/musl, macOS x86_64/aarch64, Windows x86_64)
- Verify changelog generation with git-cliff
- Verify GitHub release creation with artifacts
- Verify crates.io publishing (only for non-prereleases)
- Note: No GoReleaser needed - this is a Rust project, not Go

### 8. Cargo.toml - Verify Metadata

Review `file:Cargo.toml`:
- Verify version is ready for 1.0.0 release (currently 0.1.0)
- Verify description is accurate and compelling
- Verify keywords are relevant: "ai", "llm", "cursor", "claude", "copilot", "ide", "rules"
- Verify categories are appropriate: "command-line-utilities", "development-tools"
- Verify documentation URL points to docs.rs
- Verify repository and homepage URLs are correct
