- Fix AssetUploadStatus serialization to use snake_case (created/duplicate/rejected)
- Fix AssetOrder serialization to use lowercase (asc/desc)
- Add file_created_at/file_modified_at to UploadAssetBuilder
- Fix AddAssetsBuilder response type to Vec<Value> instead of AlbumResponse
- Fix ServerAbout model - version is String not ServerVersion struct
- Update upload_photos.rs to handle duplicate responses correctly

+# Agent Instructions for immich-sdk
+
+## Build & Test Commands
+
+**Quick Checks:**
+```bash
+cargo check                    # Fast compilation check
+cargo clippy                   # Run linter
+cargo fmt                      # Format code
+cargo test                     # Run all tests
+cargo test <test_name>         # Run single test (e.g., cargo test test_client_creation)
+```
+
+**Full verification before commit:**
+```bash
+cargo check && cargo clippy && cargo test && cargo fmt
+```
+
+## Running Examples
+
+All examples should be run using the provided wrapper script:
+
+```bash
+./scripts/run-example.sh <example_name>
+```
+
+The wrapper handles everything automatically:
+- Starts Immich containers (if not running)
+- Creates admin user and API key
+- Seeds test data (photos, albums)
+- Loads credentials
+- Runs the example
+
+**When adding new examples:**
+1. Read `IMMICH_URL` and `IMMICH_API_KEY` from environment variables
+2. Test with: `./scripts/run-example.sh <name>` (Important!)
+3. Verify it works with the seeded test data (3 photos, 1 album)
+
+## Code Style Guidelines
+
+### Imports
+- Group by: std, external crates, internal modules (crate::)
+- Use `use crate::` for internal modules, not relative paths
+- Example:
+  ```rust
+  use std::path::Path;
+  use std::sync::Arc;
+  
+  use crate::{
+      Client,
+      error::{ImmichError, Result},
+      models::AssetId,
+  };
+  ```
+
+### Types & Naming
+- Prefer using newtypes or type aliases instead of Strings or integers
+  For example: `AssetId` (Uuid alias), not `String` for asset IDs
+- Model types: PascalCase with `Response` or `Request` suffix
+- Enum variants: Use serde `rename_all` attributes for API compatibility
+- Builders: `FooBuilder` for constructing `Foo` operations
+- Type aliases for IDs: `pub type AssetId = uuid::Uuid;`
+
+### Error Handling
+- Use `crate::error::Result<T>` alias
+- Use `thiserror` for error enums
+- Prefer `ImmichError::Validation(String)` for user input errors
+- Convert external errors: `#[from] reqwest::Error`
+
+### API Design Patterns
+- **Builder pattern**: All API operations use builders
+  ```rust
+  client.assets().upload().file("path").execute().await?;
+  ```
+- Cheap cloning: `Client` wraps data in `Arc<ClientInner>`
+- API modules take `Client` by value
+- Store `Client` in builders, not references
+
+### OpenAPI
+Refer to `openapi-spec.yaml` for documentation regarding immich API.
+Note that some type definitions in this file are incorrect with regards to nullability.
+The file is big, so prefer to use nushell to query the things you need:
+```nu
+# List all api paths
+open openapi-spec.yaml | get paths | transpose key val | get key
+
+# Read the details about a particular path
+open openapi-spec.yaml | get paths.'/workflows' | to yaml
+```
+
+### Documentation
+- All public items must have doc comments
+- Module-level docs explaining purpose
+- Example code in docs should compile (use `no_run` or `ignore` if needed)
+- Include `# Errors` section for fallible methods
+
+### Rust Edition Features
+- Edition 2024 (use latest idioms)
+- Minimum Rust version: 1.85
+- Use `const fn` where possible
+- Prefer `impl Into<String>` for string parameters iff the function requires ownership of the String
+
+## Project Structure
+
+```
+src/
+  lib.rs          # Re-exports, module declarations
+  client.rs       # Client struct with Arc<ClientInner>
+  error.rs        # Error types with thiserror
+  models/         # Data models, types
+  apis/           # API modules (albums, assets, etc.)
+examples/         # Usage examples
+tests/            # Integration tests
+```
+
+## Lint Configuration
+
+From Cargo.toml - DO NOT SUPPRESS THESE:
+- `unused_async = "deny"` - No async fn without await
+- `wildcard_dependencies = "deny"` - No wildcard deps
+- `non_ascii_idents = "forbid"` - ASCII only
+- `rust_2018_idioms = "deny"` - Modern Rust idioms
+
+## Agile agentic workflow
+
+- You are responsible for high-level architecture.
+- You may (and should) read code to understand the architecture.
+- You should AVOID doing implementation work and testing. Use the `task` tool to spawn subagents for this.
+- You should also use the `task` tool to spawn subagents to for code review.
+- Prefer splitting subagent-tasks into small incremental bits of work.
+- Subagents must NEVER exit with compilation errors, but warnings due to stubbed implementations (`todo!()`) are fine.
+
+## Never Do
+
+- Never use `unsafe` without asking first
+- Never ignore clippy warnings (fix them)
+- Never suppress warnings with `#[allow(...)]`
+- Never use `panic!` or `unwrap()` in library code
+- Never break the builder pattern chain
+- Never write pointless tests to simply get more code coverage
