+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What is Sidecar?
+
+Sidecar is a Laravel package that lets you deploy and run AWS Lambda functions directly from your Laravel app. Write a function in Node, Python, Ruby, Java, or any Lambda-supported runtime, and call it from PHP as easily as `MyFunction::execute(['key' => 'value'])`.
+
+The package handles all the AWS complexity: packaging your code, uploading to S3, creating/updating Lambda functions, managing versions, and invoking them.
+
+## Testing
+
+```bash
+# Run all tests
+./vendor/bin/phpunit
+
+# Run a single test file
+./vendor/bin/phpunit tests/Unit/FunctionTest.php
+
+# Run a specific test method
+./vendor/bin/phpunit --filter test_runtime_value_resolves_enum_to_string
+```
+
+Tests use Orchestra Testbench. The test suite has unit tests in `tests/Unit/` and integration tests in `tests/Integration/`. Most development work uses unit tests with mocked AWS clients.
+
+## How the Code is Organized
+
+### The Main Players
+
+**`LambdaFunction`** is the abstract base class that users extend. Every function needs two methods:
+- `handler()` - tells Lambda which file/function to run (e.g., `'image.handler'`)
+- `package()` - lists files to include in the deployment ZIP
+
+Users call static methods like `MyFunction::execute($payload)` to run their functions.
+
+**`Manager`** (accessed via the `Sidecar` facade) does the actual work of invoking Lambda functions. It prepares payloads, calls the AWS SDK, and wraps responses in result objects.
+
+**`Deployment`** handles the deploy workflow: package the code, create or update the Lambda function, then optionally activate it by pointing an alias to the new version.
+
+**`Package`** builds the ZIP file for deployment. It collects files based on include/exclude patterns, computes a hash for change detection, and streams the ZIP directly to S3.
+
+### AWS Clients
+
+The `src/Clients/` directory has thin wrappers around AWS SDK clients:
+- `LambdaClient` extends the SDK client and adds retry logic for Lambda's "Pending" state
+- `S3Client` and `CloudWatchLogsClient` are simpler wrappers
+
+### Results
+
+When you execute a function:
+- Sync calls return a `SettledResult` with the response body, logs, and error info
+- Async calls return a `PendingResult` that resolves to `SettledResult` when you call `->settled()`
+
+### Runtime and Architecture
+
+`Runtime` and `Architecture` are PHP 8.1 backed enums. There are also deprecated `RuntimeConstants` and `ArchitectureConstants` classes for backwards compatibility.
+
+When working with these, use `runtimeValue()` and `architectureValue()` methods to get the string values - they handle both enum and string inputs.
+
+## Configuration
+
+Everything lives in `config/sidecar.php`:
+- `functions` - array of `LambdaFunction` classes to deploy
+- `env` - environment name, used to namespace function names (defaults to `APP_ENV`)
+- `timeout`, `memory`, `storage` - default Lambda settings
+- AWS credentials (`aws_key`, `aws_secret`, `aws_region`, `aws_bucket`, `execution_role`)
+
+Function names are automatically prefixed with app name and environment to avoid collisions.
+
+## Artisan Commands
+
+These are what users run (not needed for package development, but good to know):
+- `sidecar:deploy` - packages and deploys functions to Lambda
+- `sidecar:activate` - points the "active" alias to latest version
+- `sidecar:deploy --activate` - both in one step
+- `sidecar:warm` - pre-warms function instances to reduce cold starts
+- `sidecar:configure` - interactive wizard to set up AWS resources
+
+## Events
+
+The package fires Laravel events you can hook into:
+- `BeforeFunctionsDeployed` / `AfterFunctionsDeployed`
+- `BeforeFunctionsActivated` / `AfterFunctionsActivated`
+- `BeforeFunctionExecuted` / `AfterFunctionExecuted`
+
+## Things to Know
+
+- This package supports Laravel 10, 11, and 12 with PHP 8.1+
+- All source files use `declare(strict_types=1)`
+- The codebase uses constructor property promotion and typed properties throughout
+- Tests use Mockery for mocking AWS clients - check existing tests for patterns

+- Java 21: `Runtime::JAVA_21` or `'java21'`
+- Java 17: `Runtime::JAVA_17` or `'java17'`
+- Java 11: `Runtime::JAVA_11` or `'java11'`
+- Java 8: `Runtime::JAVA_8_LINUX2` or `'java8.al2'`
+- .NET 9: `Runtime::DOT_NET_9` or `'dotnet9'`

+You can use either the enum or a string:

+use Hammerstone\Sidecar\Runtime;
+
 class ExampleFunction extends LambdaFunction
 {
     public function runtime() // [tl! focus:3]
     {

-# Performance
+# Performance Tips
+
+Here are some tips for getting the best performance out of your Sidecar functions.
+
+## Reduce Cold Starts
+
+Cold starts happen when Lambda spins up a new container to handle your request. To minimize their impact:
+
+- **Use warming** - Configure `warmingConfig()` on your functions and schedule `sidecar:warm` to run regularly. See [Warming Functions](warming) for details.
+- **Use pre-warming** - Add `--pre-warm` when activating to warm functions before they go live.
+- **Keep functions warm** - Schedule `sidecar:warm` to run every 5 minutes to prevent containers from being frozen.
+
+## Optimize Your Package Size
+
+Smaller packages deploy faster and have quicker cold starts:
+
+- **Separate your node_modules** - Keep Lambda dependencies in a separate `package.json` from your main app.
+- **Use NCC** - Compile Node.js handlers into a single file with [NCC](https://github.com/vercel/ncc). See [Handlers & Packages](handlers-and-packages#compiling-your-handler-with-ncc).
+- **Only include what you need** - Be specific about what goes in your `package()` method.
+
+## Right-Size Memory
+
+Lambda allocates CPU proportionally to memory. More memory means more CPU:
+
+- **Profile your functions** - Use `$result->report()` to see memory usage and execution time.
+- **Test different memory settings** - Sometimes paying for more memory results in faster execution and lower total cost.
+
+## Use Async When Possible
+
+If you don't need the result immediately:
+
+- **Use `executeAsync()`** - Let your code continue while Lambda runs in the background.
+- **Use `executeMany()`** - Run multiple invocations in parallel instead of sequentially.
+- **Use `executeAsEvent()`** - For fire-and-forget scenarios where you don't need the response.
