+## Project Overview
+Roda (Portuguese for "wheel") is a pure Lua terminal spinner library and CLI tool for adding elegant loading indicators to bash scripts and Lua applications. It provides multiple spinner styles, colorized output, success/failure/warning states, and asynchronous command execution. The project includes a standalone executable built with static linking of luv and luasystem.
+
+## Repo Map
+- `lua/roda/` – Core Lua library modules (`init.lua`, `ansi.lua`, `spinners.lua`, etc.)
+- `spec/` – Busted unit tests (`*_spec.lua`)
+- `demo/` – Example scripts and recordings
+- `docs/` – Documentation
+- `assets/` – Images and demo GIF
+- `bin/` – CLI entry point (`spin.lua`)
+- `.github/workflows/` – CI/CD pipelines (tests, publish, release)
+- `justfile` – Primary task runner (format, lint, test, build)
+- `.luacheckrc` – Linting configuration
+- `lux.toml` – Dependency management (luasystem, luv, busted)
+
+## Setup
+- **Prerequisites:** Lua (5.1+), Lux (package manager), just (task runner), git, C compiler (for static builds)
+- **Install dependencies:** `just install` (uses Lux to fetch luasystem, luv, busted)
+- **Environment variables (optional):** `LUA_PREFIX` (path to Lua installation), `BUILD_DIR` (default `.build`), `LOG_LEVEL`
+
+## Common Commands
+All commands are run via `just <recipe>` from the repository root.
+
+| Command | Purpose |
+|---------|---------|
+| `just fmt` | Format Lua files (lux fmt) |
+| `just lint` | Lint Lua files (lux check) |
+| `just check` | Run both lint and format checks |
+| `just test-unit` | Run unit tests (via lux/busted) |
+| `just test` | Alias for `test-unit` |
+| `just test-cli` | Build the standalone binary and run CLI integration tests |
+| `just test-all` | Run unit + CLI tests |
+| `just test-perf` | Performance benchmark with hyperfine |
+| `just build` | Build standalone executable (static compile luv + luasystem) |
+| `just install` | Install lux dependencies |
+| `just dev <args>` | Run spinner directly without building (`lx lua -- bin/spin.lua`) |
+| `just validate` | Full pre‑commit validation (check + test) |
+| `just all` | Full CI pipeline (validate + build + integration tests) |
+| `just clean` | Remove build artifacts and binaries |
+| `just publish` | Publish to LuaRocks (requires confirmation) |
+
+## Coding Conventions
+- **Formatting:** Use `just fmt` (lux fmt). No manual formatting needed.
+- **Linting:** Follow `.luacheckrc` rules. Warnings are treated as errors except for ignored codes (deep nesting, long lines >120 chars, etc.).
+- **Global variables:** Only allowed globals are listed in `.luacheckrc`. Avoid adding new ones.
+- **Unused arguments:** Prefix with `_` (e.g., `_unused`) to suppress warnings.
+- **Line length:** Maximum 120 characters.
+- **Testing:** Write Busted specs in `spec/` following existing patterns. Use `describe`, `it`, `before_each`.
+- **Error handling:** Use Lua `error` and `assert` appropriately; library functions return `nil, err` on failure.
+- **Documentation:** Update README.md, CHANGELOG.md, and API reference in docs as needed.
+
+## Change Workflow
+1. **Make your change** – Ensure changes are focused and small.
+2. **Run `just check`** – Verify linting and formatting.
+3. **Run `just test-unit`** – Ensure existing tests pass.
+4. **Add/update tests** – Modify or create `*_spec.lua` files in `spec/`.
+5. **Test CLI changes** – If modifying CLI behavior, run `just test-cli`.
+6. **Build verification** – For changes to core library, run `just build` and test the binary.
+7. **Keep diffs small** – Avoid large, unrelated changes in a single commit.
+8. **Never commit secrets or credentials** – No secrets in the repository.
+
+## Gotchas
+- **Lua version:** Default development uses Lua 5.5; CI runs tests with Lua 5.4. Ensure compatibility across 5.1+.
+- **Static build dependencies:** Building the standalone binary (`just build`) clones luv and luasystem repos, compiles them statically, and links with liblua.a. Requires CMake, GCC/AR, and Lua development headers.
+- **Lux version:** CI uses Lux 0.28.0 (busted dependency issues resolved); local development uses newer versions. Be aware of version mismatches.
+- **Environment variables:** `LUA_PREFIX` may need to be set if Lua is installed in a non‑standard location (e.g., Homebrew on macOS).
+- **Performance overhead:** The CLI adds minimal overhead; benchmark with `just test-perf` to ensure it stays under 1.3s for a 1s sleep.
+- **Pre‑commit hooks:** The repo uses lefthook (see `lefthook.yml`); ensure hooks pass before committing.
+
+## When You're Stuck
+- **Ask 1 targeted question** instead of guessing or exploring blindly.
+- **If commands fail** due to environment/tooling, report the exact error and **STOP** rather than looping.
+- **Prefer the smallest reproducible check** that validates the change (e.g., `just test-unit` for library changes, `just test-cli` for CLI changes).
+- **When uncertain about architectural decisions**, ask before implementing.
+- **Check the justfile** for the exact command you need; it's the source of truth for workflows.
