anthropic: add unit and integration tests

- Unit tests for transformation functions (FromMessagesRequest, ToMessagesResponse)
- Unit tests for error handling and edge cases
- Middleware integration tests with httptest
- Fix lint issues (gofmt)
- Fix unused struct fields in StreamConverter
- Add fallback for crypto/rand errors

+Ollama Benchmark Tool
+---------------------
+
+A Go-based command-line tool for benchmarking Ollama models with configurable parameters and multiple output formats.
+
+## Features
+
+ * Benchmark multiple models in a single run
+ * Support for both text and image prompts
+ * Configurable generation parameters (temperature, max tokens, seed, etc.)
+ * Supports benchstat and CSV output formats
+ * Detailed performance metrics (prefill, generate, load, total durations)
+
+## Building from Source
+
+```
+go build -o ollama-bench bench.go
+./ollama-bench -model gpt-oss:20b -epochs 6 -format csv
+```
+
+Using Go Run (without building)
+
+```
+go run bench.go -model gpt-oss:20b -epochs 3
+```
+
+## Usage
+
+### Basic Example
+
+```
+./ollama-bench -model gemma3 -epochs 6
+```
+
+### Benchmark Multiple Models
+
+```
+./ollama-bench -model gemma3,gemma3n -epochs 6 -max-tokens 100 -p "Write me a short story" | tee gemma.bench
+benchstat -col /name gemma.bench
+```
+
+### With Image Prompt
+
+```
+./ollama-bench -model qwen3-vl -image photo.jpg -epochs 6 -max-tokens 100 -p "Describe this image"
+```
+
+### Advanced Example
+
+```
+./ollama-bench -model llama3 -epochs 10 -temperature 0.7 -max-tokens 500 -seed 42 -format csv -output results.csv
+```
+
+## Command Line Options
+
+| Option  	| Description | Default |
+|----------|-------------|---------|
+| -model	| Comma-separated list of models to benchmark	| (required)		|
+| -epochs	| Number of iterations per model		| 1			|
+| -max-tokens	| Maximum tokens for model response		| 0 (unlimited)		|
+| -temperature	| Temperature parameter				| 0.0			|
+| -seed		| Random seed					| 0 (random)		|
+| -timeout	| Timeout in seconds				| 300			|
+| -p		| Prompt text					| "Write a long story."	|
+| -image	| Image file to include in prompt		| 			|
+| -k		| Keep-alive duration in seconds		| 0			|
+| -format	| Output format (benchstat, csv)		| benchstat		|
+| -output	| Output file for results			| "" (stdout)		|
+| -v		| Verbose mode					| false			|
+| -debug	| Show debug information			| false			|
+
+## Output Formats
+
+### Markdown Format
+
+The default markdown format is suitable for copying and pasting into a GitHub issue and will look like:
+```
+ Model | Step | Count | Duration | nsPerToken | tokensPerSec |
+|-------|------|-------|----------|------------|--------------|
+| gpt-oss:20b | prefill | 124 | 30.006458ms | 241987.56 | 4132.44 |
+| gpt-oss:20b | generate | 200 | 2.646843954s | 13234219.77 | 75.56 |
+| gpt-oss:20b | load | 1 | 121.674208ms | - | - |
+| gpt-oss:20b | total | 1 | 2.861047625s | - | - |
+```
+
+### Benchstat Format
+
+Compatible with Go's benchstat tool for statistical analysis:
+
+```
+BenchmarkModel/name=gpt-oss:20b/step=prefill 128 78125.00 ns/token 12800.00 token/sec
+BenchmarkModel/name=gpt-oss:20b/step=generate 512 19531.25 ns/token 51200.00 token/sec
+BenchmarkModel/name=gpt-oss:20b/step=load 1 1500000000 ns/request
+```
+
+### CSV Format
+
+Machine-readable comma-separated values:
+
+```
+NAME,STEP,COUNT,NS_PER_COUNT,TOKEN_PER_SEC
+gpt-oss:20b,prefill,128,78125.00,12800.00
+gpt-oss:20b,generate,512,19531.25,51200.00
+gpt-oss:20b,load,1,1500000000,0
+```
+
+## Metrics Explained
+
+The tool reports four types of metrics for each model:
+
+ * prefill: Time spent processing the prompt
+ * generate: Time spent generating the response
+ * load: Model loading time (one-time cost)
+ * total: Total request duration

+Ollama provides compatibility with the [Anthropic Messages API](https://docs.anthropic.com/en/api/messages) to help connect existing applications to Ollama, including tools like Claude Code.
+
+## Usage
+
+### Environment variables
+
+To use Ollama with tools that expect the Anthropic API (like Claude Code), set these environment variables:
+
+```shell
+export ANTHROPIC_BASE_URL=http://localhost:11434
+export ANTHROPIC_API_KEY=ollama  # required but ignored

+## Using with Claude Code
+
+[Claude Code](https://docs.anthropic.com/en/docs/claude-code) can be configured to use Ollama as its backend:
+
+```shell
+ANTHROPIC_BASE_URL=http://localhost:11434 ANTHROPIC_API_KEY=ollama claude --model llama3.2:3b
+```
+
+Or set the environment variables in your shell profile:
+
+```shell
+export ANTHROPIC_BASE_URL=http://localhost:11434
+export ANTHROPIC_API_KEY=ollama
+```
+
+Then run Claude Code with any Ollama model:
+
+```shell
+claude --model llama3.2:3b
+claude --model qwen3:8b
+claude --model deepseek-r1:14b
+```

+## Models
+
+Before using a model, pull it locally with `ollama pull`:
+
+```shell
+ollama pull llama3.2:3b
+```
+
+### Default model names
+
+For tooling that relies on default Anthropic model names such as `claude-3-5-sonnet`, use `ollama cp` to copy an existing model name:
+
+```shell
+ollama cp llama3.2:3b claude-3-5-sonnet
+```
+
+Afterwards, this new model name can be specified in the `model` field:
+
+```shell
+curl http://localhost:11434/v1/messages \
+    -H "Content-Type: application/json" \
+    -d '{
+        "model": "claude-3-5-sonnet",
+        "max_tokens": 1024,
+        "messages": [
+            {
+                "role": "user",
+                "content": "Hello!"
+            }
+        ]
+    }'
+```
+
+## Differences from the Anthropic API
+
+### Behavior differences
+
+- API key is accepted but not validated
+- `anthropic-version` header is accepted but not used
+- Token counts are approximations based on the underlying model's tokenizer
+
+### Not supported
+
+The following Anthropic API features are not currently supported:
+
+| Feature | Description |
+|---------|-------------|
+| `/v1/messages/count_tokens` | Token counting endpoint |
+| `tool_choice` | Forcing specific tool use or disabling tools |
+| `metadata` | Request metadata (user_id) |
+| Prompt caching | `cache_control` blocks for caching prefixes |
+| Batches API | `/v1/messages/batches` for async batch processing |
+| Citations | `citations` content blocks |
+| PDF support | `document` content blocks with PDF files |
+| Server-sent errors | `error` events during streaming (errors return HTTP status) |
+
+### Partial support
+
+| Feature | Status |
+|---------|--------|
+| Image content | Base64 images supported; URL images not supported |
+| Extended thinking | Basic support; `budget_tokens` accepted but not enforced |

+### REQUIRES
+
+The `REQUIRES` instruction allows you to specify the minimum version of Ollama required by the model.
+
+```
+REQUIRES <version>
+```
+
+The version should be a valid Ollama version (e.g. 0.14.0).

 ## Notes
 
 - the **`Modelfile` is not case sensitive**. In the examples, uppercase instructions are used to make it easier to distinguish it from arguments.

+## How it works
+
+- Parses MDX files looking for fenced code blocks with filenames (e.g., ` ```python basic.py `)
+- Groups examples by their `<CodeGroup>` and prefixes filenames with `01_`, `02_`, etc.
+- Writes all extracted files to a temp directory

 Sometimes the Ollama can have difficulties initializing the GPU. When you check the server logs, this can show up as various error codes, such as "3" (not initialized), "46" (device unavailable), "100" (no device), "999" (unknown), or others.
