Description

This adds linting/formatting to the repo through a single Makefile for ease of use. It also adds Github CI checks for both. It also runs the linting and formatting checks on this full repo, so we now have a clean state for all future notebooks.

Local linting can be accomplished via make lint

Testing

Ran scripts locally and will validate through Github Actions

Update core dependencies to latest versions:
- anthropic 0.39.0 → 0.71.0
- ipykernel 6.29.5 → 7.1.0
- notebook 7.2.2 → 7.4.7
- numpy 1.26.4 → 2.3.4
- pandas 2.2.3 → 2.3.3

Add Makefile with common development tasks (format, lint, test, check).
Add pylint configuration for deeper code analysis.
Enhance ruff linting configuration with per-file rules for notebooks.

Claude Model Usage Review

Summary

Overall Status: GOOD - All model references in changed files use current public models from the Claude 4+ family.

Current Allowed Models (as of documentation)

Based on https://docs.claude.com/en/docs/about-claude/models/overview.md:

Latest Models:

  • Claude Sonnet 4.5: claude-sonnet-4-5-20250929 (alias: claude-sonnet-4-5)
  • Claude Haiku 4.5: claude-haiku-4-5-20251001 (alias: claude-haiku-4-5)
  • Claude Opus 4.1: claude-opus-4-1-20250805 (alias: claude-opus-4-1)

Findings

✅ Valid Model Usage

All model references in changed files use valid current models:

  • claude-sonnet-4-5 - Most commonly used (aliases and full IDs)
  • claude-haiku-4-5 - Used appropriately for fast tasks
  • claude-opus-4-1 - Used for complex reasoning tasks
  • claude-sonnet-4-5-20250929 - Full version ID (valid but see recommendation below)
  • claude-haiku-4-5-20251001 - Full version ID (valid but see recommendation below)

📋 Key Files Reviewed

Changed files containing model references:

  • capabilities/classification/guide.ipynb
  • capabilities/contextual-embeddings/guide.ipynb
  • capabilities/retrieval_augmented_generation/guide.ipynb
  • capabilities/summarization/guide.ipynb
  • capabilities/text_to_sql/guide.ipynb
  • misc/ notebooks (batch_processing, building_moderation_filter, etc.)
  • tool_use/ notebooks (calculator_tool, customer_service_agent, memory_cookbook, etc.)
  • multimodal/ notebooks
  • skills/ notebooks
  • finetuning/finetuning_on_bedrock.ipynb
  • Various Python scripts and configuration files

💡 Recommendations

  1. Consider using -latest aliases for better maintainability

    • The documentation recommends aliases like claude-sonnet-4-5 over full version IDs
    • Aliases automatically point to the most recent snapshot (typically within a week of new releases)
    • Current usage is already good - most files use aliases appropriately
    • A few files use full version IDs (e.g., claude-sonnet-4-5-20250929), which is fine for production stability but consider whether the extra specificity is needed
  2. Model selection appears appropriate

    • Haiku used for fast, simple tasks (classification, moderation)
    • Sonnet used for general-purpose workflows (most cookbooks)
    • Opus used for complex reasoning (multi-agent systems, vision tasks)

📊 Special Notes

  1. Validation Scripts (scripts/validate_all_notebooks.py): Contains deprecation mappings for older models (Claude 3.x) → Claude 4.x, which is excellent for maintaining backwards compatibility

  2. Data Files: Some CSV/JSON files reference deprecated models like claude-3-haiku-20240307 in test data/examples - these appear to be historical data for evaluation purposes and don't represent actual API calls

  3. AWS Bedrock: finetuning/finetuning_on_bedrock.ipynb correctly uses the Bedrock-specific model ARN format

Conclusion

✅ No action required - all model references are valid and follow best practices. The codebase is already using the current Claude 4+ model family appropriately.

Notebook Review Summary

I've reviewed the changes in PR #253 which adds Ruff formatting and linting across the codebase. Here's my assessment:

✅ What Looks Good

Infrastructure & Tooling

  • Excellent addition of automated linting/formatting with Ruff - this will significantly improve code consistency
  • Well-structured GitHub Actions workflow (.github/workflows/lint-format.yml:1-113) with clear steps and helpful summaries
  • Pre-commit hooks properly configured to catch issues before commits
  • Makefile provides convenient commands (make fix, make check) for local development
  • Comprehensive pyproject.toml configuration with appropriate rules for notebooks vs regular Python files

Code Quality Improvements

  • All 104 files have been consistently formatted (10,429 insertions, 10,615 deletions)
  • Proper quote style standardization (double quotes throughout)
  • Consistent spacing and indentation across Python files and notebooks
  • Import statement organization improved (blank lines added after imports)
  • Line length compliance (100 chars max)

Notebook Validation

  • Added validate_notebooks.py script to check for empty cells and error outputs
  • Pre-commit hook integration ensures notebooks are validated before commits

Python Code Examples

  • capabilities/classification/evaluation/prompts.py:1-222 - Clean formatting with proper multiline string handling
  • capabilities/text_to_sql/evaluation/prompts.py:1-222 - Good code structure and readability
  • tool_use/memory_tool.py:1-50 - Professional docstrings and security considerations

⚠️ Suggestions for Improvement

Documentation

  • Consider adding a section to the main README about the new linting/formatting requirements
  • The Makefile help command is great, but might benefit from being documented in contributing guidelines

Workflow Optimization

  • .github/workflows/lint-format.yml:45-52 - The format-check step uses continue-on-error: true which is good, but consider if you want to fail fast or collect all issues
  • .github/workflows/lint-format.yml:75-97 - The Claude Code action integration is interesting but adds complexity; ensure the ANTHROPIC_API_KEY secret is properly secured

Notebook Validation Script

  • scripts/validate_notebooks.py:36 - Currently only processes files that end with .ipynb from command line args; consider adding a check to ensure the file exists before processing
  • The error output checking is good, but might want to make it configurable (some development notebooks might intentionally show errors for educational purposes)

Python Code Quality

  • capabilities/text_to_sql/evaluation/prompts.py:18 - SQL injection risk: Using f-string formatting in PRAGMA table_info({table_name}) - while table names from sqlite_master are generally safe, consider parameterized queries for consistency
  • capabilities/text_to_sql/evaluation/prompts.py:156 - Similar f-string usage in SQL query

❌ Critical Issues

None found! The PR is well-executed and ready to merge from a code quality perspective.

Additional Notes

The changes are primarily formatting-related (consistent spacing, quotes, line breaks) rather than logic changes, which is exactly what you'd expect from a linting/formatting PR. The fact that the net line count decreased slightly (10,615 → 10,429) suggests the formatter is making the code more concise.

The Ruff configuration in pyproject.toml is well-thought-out with appropriate ignores for notebooks (E402 for mid-file imports, F811 for redefinitions).

Great work on improving the codebase infrastructure! 🎉

Claude Model Usage Review - Findings

I've reviewed the changed files for Claude model usage against the current public models list. Here are my findings:

✅ Issues Found

1. Deprecated Model: claude-2 (CRITICAL)

  • File: third_party/Wikipedia/wikipedia-search-cookbook.ipynb:464
  • Issue: Uses claude-2 which is deprecated and no longer available
  • Recommendation: Update to claude-sonnet-4-5 or claude-haiku-4-5 depending on use case requirements

2. Deprecated Model: claude-2.1 (CRITICAL)

  • File: third_party/Pinecone/rag_using_pinecone.ipynb:398
  • Issue: Uses claude-2.1 which is deprecated and no longer available
  • Recommendation: Update to claude-sonnet-4-5 or claude-haiku-4-5

3. Invalid Model Name: claude-4.5-haiku (CRITICAL)

  • File: third_party/WolframAlpha/using_llm_api.ipynb:34
  • Issue: Model name claude-4.5-haiku is incorrect. The correct name is claude-haiku-4-5
  • Recommendation: Change to claude-haiku-4-5 (note the different ordering)

📋 Current Valid Models (as of Jan 2025)

Latest Models (Recommended):

  • claude-sonnet-4-5 (alias for claude-sonnet-4-5-20250929)
  • claude-haiku-4-5 (alias for claude-haiku-4-5-20251001)
  • claude-opus-4-1 (alias for claude-opus-4-1-20250805)

💡 Best Practices

  1. Use -latest aliases or version-less aliases (like claude-sonnet-4-5) for better maintainability
  2. Migrate from Claude 2.x models - they are no longer available
  3. Start with Claude Sonnet 4.5 for the best balance of intelligence, speed, and cost

🔍 Notes

The validation scripts (scripts/validate_all_notebooks.py) correctly map deprecated models to their modern equivalents, which is good infrastructure. However, the notebooks themselves should be updated to use current models directly.

Notebook and Code Review - PR #253: Add formatting/linting to repo

This PR adds comprehensive formatting and linting infrastructure to the repository using ruff. I've reviewed the changes across notebooks and Python scripts.


✅ What Looks Good

Infrastructure Setup

  • GitHub Workflow (.github/workflows/lint-format.yml): Well-designed CI workflow that:

    • Only checks changed files (efficient)
    • Runs on PRs and main branch pushes
    • Uses continue-on-error to collect all issues before failing
    • Includes helpful PR comments via claude-code-action
    • Clear step summaries for debugging
  • Makefile: Excellent developer experience with clear targets:

    • make check - Run all checks locally
    • make fix - Auto-fix issues
    • make format / make lint - Individual operations
    • Clear help text
  • pyproject.toml: Sensible ruff configuration:

    • Line length of 100 (good for notebooks)
    • Per-file ignores for notebooks (E402, F811, etc.) - appropriate for notebook conventions
    • Targets Python 3.11+
    • Includes notebooks in formatting scope
  • Pre-commit hooks: Configured for local development with ruff checks

Code Quality Improvements

Notebooks - Consistent formatting applied across all 90+ notebooks:

  • Double quotes standardized
  • Proper spacing around operators and after commas
  • Consistent indentation (4 spaces)
  • Trailing whitespace removed
  • Blank lines normalized

Python Scripts - Clean formatting throughout:

  • capabilities/classification/evaluation/prompts.py: Clean function definitions
  • skills/skill_utils.py: Excellent docstrings and type hints maintained
  • tool_use/memory_tool.py: Security-conscious implementation

Specific Notebook Highlights

capabilities/classification/guide.ipynb:

  • Proper formatting of data structures (dictionaries, pandas operations)
  • Consistent string quoting
  • Clean function definitions with proper spacing
  • Well-structured evaluation code

tool_use/memory_cookbook.ipynb:

  • Clear markdown cells with good structure
  • Properly formatted code cells
  • Good examples of helper function usage
  • Security considerations documented

misc/prompt_caching.ipynb:

  • Clean API call examples
  • Proper class definitions
  • Good formatting of multi-line strings and f-strings

⚠️ Suggestions for Improvement

1. Documentation

Issue: No README or documentation for the new linting/formatting setup

Suggestion: Add a section to the main README explaining:

  • How to set up pre-commit hooks: pre-commit install
  • How to run checks locally: make check
  • How to auto-fix issues: make fix
  • What to do when CI fails

Example:

## Code Quality

This repository uses [ruff](https://docs.astral.sh/ruff/) for linting and formatting.

### Setup
```bash
# Install pre-commit hooks (runs checks automatically before commits)
pre-commit install

# Install dependencies
make install

Usage

make check  # Run all checks
make fix    # Auto-fix issues
make format # Format code
make lint   # Run linter only

### 2. CI Workflow Enhancement
**Issue**: The workflow could be more informative when it posts comments

**Current**: Posts lint output but could be more structured

**Suggestion**: Consider enhancing the claude-code-action prompt to:
- Group issues by file
- Prioritize critical issues
- Link to specific line numbers in the PR

### 3. Pre-commit Config Version
**Issue**: Ruff version in .pre-commit-config.yaml (v0.12.12) is older than pyproject.toml (>=0.14.2)

**Suggestion**: Update .pre-commit-config.yaml to match:
```yaml
- repo: https://github.com/astral-sh/ruff-pre-commit
  rev: v0.14.2  # Match pyproject.toml version

4. Notebook-Specific Ignores

Observation: The per-file ignores for notebooks are good, but consider adding:

  • E501 (line too long) for notebooks with long markdown cells
  • T201 (print statements) - common and acceptable in notebooks

Suggestion in pyproject.toml:

[tool.ruff.lint.per-file-ignores]
"*.ipynb" = [
    "E402",   # imports mid-file
    "E501",   # line too long (markdown cells can be long)
    "F811",   # redefinitions (common in notebooks)
    "N803",   # argument name should be lowercase
    "N806",   # variable in function should be lowercase
    "T201",   # print statements (expected in notebooks)
]

5. File Deletions

Observation: Two notebooks were deleted:

  • misc/illustrated_responses.ipynb (529 lines)
  • misc/mc_qa.ipynb (1461 lines)

Suggestion: Ensure this was intentional and not accidental. If intentional, consider adding a note in the PR description explaining why these were removed.


❌ Critical Issues

None Found! 🎉

No critical issues detected. The PR successfully:

  • Maintains code functionality
  • Applies formatting consistently
  • Sets up proper CI/CD infrastructure
  • Follows Python and Jupyter notebook best practices

Summary Statistics

  • Total files changed: 96 files
  • Notebooks formatted: ~50 .ipynb files
  • Python scripts formatted: ~46 .py files
  • Lines added: ~7,000+ (mostly formatting)
  • Lines removed: ~6,000+ (mostly formatting + 2 deleted notebooks)

Recommendation

Approve with minor suggestions

This PR significantly improves the codebase quality and developer experience. The formatting is consistent, the tooling is well-chosen, and the CI integration is solid. The suggestions above are minor enhancements that can be addressed in follow-up PRs if needed.

Action Items (Optional, can be follow-up PRs):

  1. Add setup documentation to README
  2. Update pre-commit config to match pyproject.toml version
  3. Consider additional notebook-specific linting ignores
  4. Verify the two deleted notebooks were intentionally removed

Great work on this infrastructure improvement! 🚀 The consistent formatting will make code reviews easier and improve overall code quality going forward.

⚠️ Minor Observations

1. Internal Artifact Repository (Informational)

Location: capabilities/retrieval_augmented_generation/guide.ipynb (7 occurrences)

https://reader2:****@artifactory.infra.ant.dev/artifactory/api/pypi/pypi-all/simple

Note: This appears to be an internal Anthropic artifact repository with masked credentials. This is appropriate for internal development but should be verified that it's intentionally included in the public cookbook. If this is meant for internal use only, consider:

  • Removing it from public examples
  • Replacing with public PyPI index
  • Adding a note explaining this is for internal development only

Severity: Low - Credentials are already masked, no security risk


🔒 Security Assessment

All Links Meet Security Standards:

  1. HTTPS Usage: All external links use HTTPS (except localhost examples)
  2. No Suspicious Domains: All domains are reputable and verified
  3. No Malformed URLs: All URLs are properly formatted
  4. No Deprecated Resources: All documentation links point to current versions
  5. Credential Handling: The one instance with credentials is properly masked

📝 Best Practices Compliance

Followed:

  • Links use HTTPS where appropriate
  • External links point to stable, reputable sources
  • GitHub links use correct repository paths
  • API documentation links are current
  • Model references are up-to-date

Internal vs External Links:

  • Internal GitHub cookbook references use full GitHub URLs (appropriate for notebooks)
  • API endpoint examples use full URLs (appropriate for educational content)

🎯 Recommendations

Optional Improvements:

  1. Internal Artifact Repository: Review whether the internal artifactory references in the RAG guide should be in the public cookbook, or replace with public alternatives.

No Action Required For:

  • All other links are production-ready
  • No broken links detected
  • No security issues found
  • All documentation links are current

Final Verdict

This PR passes link review with flying colors. All 120+ links are:

  • ✅ Properly formatted
  • ✅ Using HTTPS (where appropriate)
  • ✅ Pointing to current, active resources
  • ✅ From reputable sources
  • ✅ Secure and safe

The only minor observation is the internal artifact repository reference, which is already properly secured with masked credentials and poses no immediate concern.

Ready to merge from a link quality perspective! 🚀

Notebook and Code Review Summary

I've completed a comprehensive review of 98 changed files (notebooks and Python scripts). Here's my assessment:

✅ What Looks Good

Code Quality

  • Well-structured notebooks: All reviewed notebooks follow clear pedagogical structure with markdown explanations, code examples, and practical demonstrations
  • Strong documentation: Notebooks include detailed explanations, prerequisites, setup instructions, and step-by-step walkthroughs
  • Good examples: Real-world use cases demonstrated (insurance ticket classification, legal document summarization, batch processing, etc.)
  • Security best practices: Memory tool handler (tool_use/memory_tool.py:37-74) implements proper path validation and security controls
  • Comprehensive testing: Test suite for memory tool (tool_use/tests/test_memory_tool.py) covers security, functionality, and edge cases
  • Clean utilities: Helper functions are well-documented with docstrings and type hints

Python Code

  • PEP 8 compliance: Python files appear to follow standard formatting (after ruff formatting)
  • Type hints: Good use of type annotations in utility files (e.g., skill_utils.py, memory_tool.py)
  • Error handling: Proper try-except blocks with informative error messages
  • Modular design: Code is well-organized into reusable functions and classes

Notebooks Structure

  • Clear progression from basic to advanced concepts
  • Effective use of examples and visual aids
  • Good balance between explanation and code
  • Proper use of markdown for section headers and formatting

⚠️ Suggestions for Improvement

Notebooks

  1. Model naming consistency (Multiple notebooks)

    • Some notebooks use claude-sonnet-4-5, others use claude-haiku-4-5, and some use older formats like claude-opus-4-1
    • Recommendation: Standardize model names and ensure they match currently available models. Consider using a constant defined at the top of each notebook.
    • Affected files: Most notebooks use varying model names
  2. API key handling (misc/summarization/guide.ipynb:cell-2)

    • Shows direct API key assignment: api_key = "ANTHROPIC_API_KEY"
    • Recommendation: Always show environment variable usage as the primary method:
    import os
    api_key = os.getenv("ANTHROPIC_API_KEY")
    • This is done correctly in most other notebooks
  3. Large output truncation (Multiple notebooks)

    • Several notebooks show "Outputs are too large to include" warnings
    • Recommendation: Consider using head_limit or truncating verbose outputs in cells to keep notebooks lean
  4. Error output in cells

    • Need to verify no cells have execution errors captured in outputs
    • The validation script (scripts/validate_notebooks.py) checks for this
  5. Empty cells

    • Validation script checks for empty cells - ensure all cells have content

Python Files

  1. Hard-coded values (capabilities/classification/evaluation/prompts.py)

    • Categories are hard-coded as a large XML string
    • Recommendation: Consider loading from a config file or constants module for easier maintenance
  2. Eval function usage (tool_use/calculator_tool.ipynb:cell-5)

    • Uses eval() with a warning comment acknowledging it's bad practice
    • Recommendation: While this is for demonstration, consider showing a safer alternative using ast.literal_eval() or a proper expression parser
  3. Import organization

    • Some files could benefit from organizing imports (stdlib, third-party, local)
    • Already addressed by ruff formatting in most cases

Documentation

  1. Prerequisites clarity

    • Some notebooks list dependencies but don't specify minimum versions
    • Recommendation: Where version-specific features are used, note minimum versions
  2. Setup consistency

    • Some notebooks use %pip install, others use !pip install
    • Recommendation: Standardize on %pip install (preferred in modern Jupyter)

❌ Critical Issues That Must Be Fixed

High Priority

  1. Model availability validation

    • Several notebooks reference model names that may not match the current Claude API
    • Action required: Run the /model-check command to validate all model references
    • Files to check: All notebooks, especially:
      • tool_use/calculator_tool.ipynb (uses claude-opus-4-1)
      • Various notebooks using claude-haiku-4-5 or claude-sonnet-4-5
  2. Execution state

    • Notebooks should be checked for:
      • Error outputs in cells
      • Empty cells
      • Incomplete executions
    • Action required: Run python scripts/validate_notebooks.py on all changed notebooks
  3. Missing validation

    • The validate_notebooks.py script should be run as part of CI/CD
    • Verification needed: Confirm the GitHub workflow is properly configured to run on these changed files

Medium Priority

  1. Security in eval() usage

    • While marked as demonstration-only, the calculator tool's use of eval() could be misunderstood
    • Recommendation: Add stronger warnings or show both unsafe and safe versions
  2. Hardcoded paths

    • Some notebooks reference relative paths that might break depending on execution context
    • Check: Ensure all file paths work from the notebook's directory

Model Check Results

❌ Issues Found

Invalid Model Name

File: third_party/WolframAlpha/using_llm_api.ipynb:34

  • Current: MODEL_NAME = "claude-4.5-haiku"
  • Issue: This is not a valid model name. The correct format is claude-haiku-4-5
  • Recommendation: Change to claude-haiku-4-5 or use the full version claude-haiku-4-5-20251001

Deprecated Model Reference

File: misc/using_citations.ipynb:13

  • Current: claude-3-5-haiku-20241022
  • Status: This is a deprecated/legacy model
  • Recommendation: Update to current Haiku model: claude-haiku-4-5 or claude-haiku-4-5-20251001

✅ Good Practices Observed

The majority of files are using current, valid model names:

  • claude-sonnet-4-5 (Sonnet 4.5 alias)
  • claude-haiku-4-5 (Haiku 4.5 alias)
  • claude-opus-4-1 (Opus 4.1 alias)
  • claude-sonnet-4-5-20250929 (full version with date)
  • claude-haiku-4-5-20251001 (full version with date)

📋 Current Valid Models (as of October 2025)

Sonnet Family:

  • claude-sonnet-4-5 (alias - recommended)
  • claude-sonnet-4-5-20250929 (dated version)

Haiku Family:

  • claude-haiku-4-5 (alias - recommended)
  • claude-haiku-4-5-20251001 (dated version)

Opus Family:

  • claude-opus-4-1 (alias - recommended)
  • claude-opus-4-1-20250805 (dated version)

💡 Recommendations

  1. Fix the invalid model name in third_party/WolframAlpha/using_llm_api.ipynb - this will cause runtime errors
  2. Update deprecated model in misc/using_citations.ipynb for better performance
  3. Consider using alias versions (e.g., claude-haiku-4-5) instead of dated versions for easier maintenance, unless you need to pin to a specific model version

📝 Comprehensive Notebook Review

Reviewed 98 changed files including notebooks, Python scripts, and evaluation code.


✅ What Looks Good

Model Usage

  • ✨ Consistent use of modern Claude models (claude-sonnet-4-5, claude-haiku-4-5)
  • ✨ Proper temperature settings for deterministic tasks (temperature=0)
  • ✨ Good model selection guidance (Haiku for speed, Sonnet for accuracy)

Code Quality

  • 📚 Well-structured notebooks with clear educational progression
  • 🎯 Comprehensive real-world examples (RAG, classification, summarization)
  • 🏷️ Excellent use of XML tags for structured prompting
  • 📊 Robust evaluation frameworks with multiple metrics (Precision, Recall, F1, MRR)

Documentation

  • 📖 Detailed step-by-step explanations with conceptual context
  • 📈 Good visualizations for performance comparisons
  • 💡 Clear best practices and anti-patterns demonstrated
  • 🔧 Helpful setup instructions with prerequisites

Advanced Techniques Demonstrated

  • ⚡ Prompt caching with cost/performance analysis
  • 🔍 Contextual embeddings with 35% retrieval improvement
  • 🎓 Few-shot learning and chain-of-thought prompting
  • 🔁 Hybrid search (semantic + BM25) with reranking

⚠️ Suggestions for Improvement

1. API Key Management Consistency

Files: capabilities/summarization/guide.ipynb, others

Current:

api_key = "ANTHROPIC_API_KEY"  # Hardcoded placeholder

Recommended:

import os
api_key = os.getenv('ANTHROPIC_API_KEY')

# Or with dotenv
from dotenv import load_dotenv
load_dotenv()
api_key = os.getenv('ANTHROPIC_API_KEY')

2. Rate Limiting Documentation

Files: capabilities/classification/guide.ipynb

Issue: MAXIMUM_CONCURRENT_REQUESTS = 5 may hit rate limits for lower tiers

Recommendation: Add prominent note:

# Note: Adjust based on your rate limit tier
# Tier 1: Use 1-2 concurrent requests
# Tier 2+: Can use 5+ concurrent requests
# See: https://docs.claude.com/en/api/rate-limits
MAXIMUM_CONCURRENT_REQUESTS = 5

3. Model Name Variable Standardization

Issue: Mixed patterns (MODEL, MODEL_NAME, model)

Recommendation: Standardize on MODEL_NAME and define early in notebooks:

MODEL_NAME = "claude-sonnet-4-5"

4. Error Handling in Evaluation Loops

Files: Multiple evaluation scripts

Recommendation: Add graceful error handling:

try:
    response = client.messages.create(...)
except anthropic.RateLimitError:
    print(f"Rate limit hit, waiting...")
    time.sleep(60)
except Exception as e:
    logging.error(f"Error processing item {i}: {e}")
    continue

5. Validation Script Enhancements

File: scripts/validate_notebooks.py

Suggested additions:

  • Check for API key placeholder patterns
  • Validate model names against current Claude models
  • Verify prompt caching header consistency
  • Check for empty output cells that might indicate failed execution

❌ Critical Issues That Must Be Fixed

1. ⚠️ Missing Prompt Caching Beta Header

Severity: HIGH
Impact: Prompt caching features won't work without this header

Files needing review: All notebooks using cache_control

Example from capabilities/contextual-embeddings/guide.ipynb:

Current (cell 18):

response = client.messages.create(
    model=MODEL_NAME,
    max_tokens=1024,
    temperature=0.0,
    messages=[...],
    # Missing beta header\!
)

Required Fix:

response = client.messages.create(
    model=MODEL_NAME,
    max_tokens=1024,
    temperature=0.0,
    messages=[...],
    extra_headers={"anthropic-beta": "prompt-caching-2024-07-31"}  # ADD THIS
)

✅ Good example: misc/prompt_caching.ipynb properly includes the header

2. ⚠️ Invalid Tool Schema in JSON Extraction Example

File: tool_use/extracting_structured_json.ipynb (cell 5)
Severity: HIGH

Issue: counterpoint is in required array but not defined in properties

Current:

"properties": {
    "author": {...},
    "topics": {...},
    "summary": {...},
    "coherence": {...},
    "persuasion": {...},
    # counterpoint is missing\!
},
"required": ["author", "topics", "summary", "coherence", "persuasion", "counterpoint"]

Fix Option 1 - Remove from required:

"required": ["author", "topics", "summary", "coherence", "persuasion"]

Fix Option 2 - Add to properties:

"counterpoint": {
    "type": "string",
    "description": "A counterargument or alternative perspective"
}

3. ⚠️ Hardcoded API Key Example

File: capabilities/summarization/guide.ipynb (cell 2)
Severity: MEDIUM

Current:

api_key = "ANTHROPIC_API_KEY"  # Replace ANTHROPIC_API_KEY with your actual API key

This encourages bad practices. Should be:

# Best practice: Use environment variables
import os
api_key = os.getenv("ANTHROPIC_API_KEY")

if not api_key:
    raise ValueError("Please set ANTHROPIC_API_KEY environment variable")
