best-practices

Searchable knowledge base of 170+ programming best practices across 35+ languages and frameworks. BM25-powered search over curated resources from industry leaders (Google, Airbnb, Uber, Mozilla, Microsoft, Shopify, OWASP, Anthropic, OpenAI).

Prerequisites

Python 3 must be installed:

python3 --version

How to Use This Workflow

When user asks about coding standards, best practices, style guides, code review, architecture, security, or performance for any language/framework, follow this workflow:

Step 1: Analyze User Requirements

Extract from user request:

• Language/Framework: Python, JavaScript, Go, React, Rails, etc.
• Topic: style guide, design patterns, performance, security, clean code, etc.
• Depth: quick reference vs. deep dive

Step 2: Search Best Practices (REQUIRED)

Always start with --recommend to get comprehensive results (resources + deep content):

python3 skills/best-practices/scripts/search.py "<language> <topic>" --recommend

Examples:

python3 skills/best-practices/scripts/search.py "python style guide" --recommend
python3 skills/best-practices/scripts/search.py "javascript clean code" --recommend
python3 skills/best-practices/scripts/search.py "react performance" --recommend
python3 skills/best-practices/scripts/search.py "sql optimization" --recommend
python3 skills/best-practices/scripts/search.py "api security" --recommend

Step 3: Supplement with Domain Searches (as needed)

# Search all resources (default)
python3 skills/best-practices/scripts/search.py "<query>" --domain resource

# Search by language/technology overview
python3 skills/best-practices/scripts/search.py "<query>" --domain language

# Search by category
python3 skills/best-practices/scripts/search.py "<query>" --domain category

# Deep search within crawled content files
python3 skills/best-practices/scripts/search.py "<query>" --content

# Deep search filtered by language
python3 skills/best-practices/scripts/search.py "<query>" --content --lang python

Step 4: Read Deep Content (when needed)

When a search result includes a File path, read it for detailed content:

content/core_technologies/250af6826bbd.md  → Google JavaScript Style Guide
content/web_backend/b8aad3894efa.md        → Python Code Style Guide

Rebuilding the CSV Database

If new content is crawled, regenerate the CSVs:

python3 skills/best-practices/scripts/generate_csv.py

This reads content/index.json and produces:

• data/resources.csv — All 170+ resources with metadata
• data/languages.csv — Aggregated by language/technology
• data/categories.csv — Aggregated by category
