## Quick Reference
### Basic API Usage
```python
import anthropic
client = anthropic.Anthropic(api_key="your-api-key")
# Simple message
response = client.messages.create(
model="claude-3-5-sonnet-20241022",
max_tokens=1024,
messages=[{
"role": "user",
"content": "Hello, Claude!"
}]
)
```
### Tool Use (Function Calling)
```python
# Define a tool
tools = [{
"name": "get_weather",
"description": "Get current weather for a location",
"input_schema": {
"type": "object",
"properties": {
"location": {"type": "string", "description": "City name"}
},
"required": ["location"]
}
}]
# Use the tool
response = client.messages.create(
model="claude-3-5-sonnet-20241022",
max_tokens=1024,
tools=tools,
messages=[{"role": "user", "content": "What's the weather in San Francisco?"}]
)
```
### Vision (Image Analysis)
```python
# Analyze an image
response = client.messages.create(
model="claude-3-5-sonnet-20241022",
max_tokens=1024,
messages=[{
"role": "user",
"content": [
{
"type": "image",
"source": {
"type": "base64",
"media_type": "image/jpeg",
"data": base64_image
}
},
{"type": "text", "text": "Describe this image"}
]
}]
)
```

model="claude-3-5-sonnet-20241022",
max_tokens=1024,
system=[{
"type": "text",
"text": "Large system prompt here...",

3. Implement conversation memory
4. Add fallback mechanisms
See: `references/tool_use.md#customer-service`
### Implementing RAG
1. Create embeddings of your documents
2. Store in vector database (Pinecone, etc.)
3. Retrieve relevant context on query
4. Augment Claude's response with context
See: `references/capabilities.md#rag`
### Processing Documents with Vision
1. Convert document to images or PDF
2. Use vision API to extract content
3. Structure the extracted data
4. Validate and post-process
See: `references/multimodal.md#vision`
### Building Multi-Agent Systems
1. Define specialized agents for different tasks
2. Implement routing logic
3. Use sub-agents for delegation
4. Aggregate results
See: `references/patterns.md#agents`
## Best Practices
### API Usage
- Use appropriate model for task (Sonnet for balance, Haiku for speed, Opus for complex tasks)
- Implement retry logic with exponential backoff
- Handle rate limits gracefully
- Monitor token usage for cost optimization
### Prompt Engineering
- Be specific and clear in instructions
- Provide examples when needed
- Use system prompts for consistent behavior
- Structure outputs with JSON mode when needed
### Tool Use
- Define clear, specific tool schemas
- Validate inputs and outputs
- Handle errors gracefully
- Keep tool descriptions concise but informative
### Multimodal
- Use high-quality images (higher resolution = better results)
- Be specific about what to extract/analyze
- Respect size limits (5MB per image)
- Use appropriate image formats (JPEG, PNG, GIF, WebP)
## Performance Optimization
### Prompt Caching
- Cache large system prompts
- Cache frequently used context
- Monitor cache hit rates
- Balance caching vs. fresh content
### Cost Optimization
- Use Haiku for simple tasks
- Implement prompt caching for repeated context
- Set appropriate max_tokens
- Batch similar requests
### Latency Optimization
- Use streaming for long responses
- Minimize message history
- Optimize image sizes
- Use appropriate timeout values

## Examples Available
The cookbook includes 50+ practical examples including:
- Customer serRelated in Writing & Docs
jax-development
IncludedUse this skill when the user is writing, debugging, profiling, refactoring, reviewing, benchmarking, parallelising, exporting, or explaining JAX code, or when they mention JAX, jax.numpy, jit, grad, value_and_grad, vmap, scan, lax, random keys, pytrees, jax.Array, sharding, Mesh, PartitionSpec, NamedSharding, pmap, shard_map, Pallas, XLA, StableHLO, checkify, profiler, or the JAX repo. It helps turn NumPy or PyTorch-style code into pure functional JAX, fix tracer/control-flow/shape/PRNG bugs, remove recompiles and host-device syncs, choose transforms and sharding strategies, inspect jaxpr/lowering/IR, and benchmark compiled code correctly.
nature-article-writer
IncludedDrafts, rewrites, diagnostically critiques, and style-calibrates primary research manuscripts for Nature and Nature Portfolio journals. Use when the user wants a Nature-style title, summary paragraph or abstract, introduction, results, discussion, methods, figure legends, presubmission enquiry, cover letter, reviewer response, or when a scientific draft sounds generic, jargon-heavy, structurally weak, or AI-ish and needs precise, broad-reader-friendly prose without inventing data, analyses, or references. Best for primary research articles and letters rather than reviews or press releases unless explicitly adapting one.
deckrd
IncludedDocument-driven framework that derives requirements, specifications, implementation plans, and executable tasks from goals through structured AI dialogue. Use when user says "write requirements", "create spec", "plan implementation", "derive tasks", "structure this feature", "break down into tasks", or "document this module". Also use for reverse engineering existing code into docs (/deckrd rev). Do NOT use for direct code writing — use /deckrd-coder after tasks are generated. Do NOT use when the user only wants to run or fix existing code without planning.
clinical-decision-support
IncludedGenerate professional clinical decision support (CDS) documents for pharmaceutical and clinical research settings, including patient cohort analyses (biomarker-stratified with outcomes) and treatment recommendation reports (evidence-based guidelines with decision algorithms). Supports GRADE evidence grading, statistical analysis (hazard ratios, survival curves, waterfall plots), biomarker integration, and regulatory compliance. Outputs publication-ready LaTeX/PDF format optimized for drug development, clinical research, and evidence synthesis.
handling-sf-data
IncludedSalesforce data operations with 130-point scoring. Use this skill to create, update, delete, bulk import/export, generate test data, and clean up org records using sf CLI and anonymous Apex. TRIGGER when: user creates test data, performs bulk import/export, uses sf data CLI commands, needs data factory patterns for Apex tests, or needs to seed/clean records in a Salesforce org. DO NOT TRIGGER when: SOQL query writing only (use querying-soql), Apex test execution (use running-apex-tests), or metadata deployment (use deploying-metadata).
accelint-ac-to-playwright
IncludedConvert and validate acceptance criteria for Playwright test automation. Use when user asks to (1) review/evaluate/check if AC are ready for automation, (2) assess if AC can be converted as-is, (3) validate AC quality for Playwright, (4) turn AC into tests, (5) generate tests from acceptance criteria, (6) convert .md bullets or .feature Gherkin files to Playwright specs, (7) create test automation from requirements. Handles both bullet-style markdown and Gherkin syntax with JSON test plan generation and validation.
