Examples

Development Environment

# Debug mode
export SKILL_SEEKERS_DEBUG=1
export SKILL_SEEKERS_LOG_LEVEL=DEBUG

# Custom paths
export SKILL_SEEKERS_HOME=./.skill-seekers
export SKILL_SEEKERS_OUTPUT=./output

# Faster scraping for testing
export SKILL_SEEKERS_RATE_LIMIT=0.1
export SKILL_SEEKERS_MAX_PAGES=50

Production Environment

# API keys
export ANTHROPIC_API_KEY=sk-ant-...
export GITHUB_TOKEN=ghp_...

# Custom output directory
export SKILL_SEEKERS_OUTPUT=/var/www/skills

# Conservative scraping
export SKILL_SEEKERS_RATE_LIMIT=1.0
export SKILL_SEEKERS_WORKERS=2

# Logging
export SKILL_SEEKERS_LOG_FILE=/var/log/skill-seekers.log
export SKILL_SEEKERS_LOG_LEVEL=WARNING

CI/CD Environment

# Non-interactive
export SKILL_SEEKERS_LOG_LEVEL=ERROR

# API keys from secrets
export ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY_SECRET}
export GITHUB_TOKEN=${GITHUB_TOKEN_SECRET}

# Fresh runs (no cache)
export SKILL_SEEKERS_NO_CACHE=1

Multi-Platform Setup

# All API keys
export ANTHROPIC_API_KEY=sk-ant-...
export GOOGLE_API_KEY=AIza...
export OPENAI_API_KEY=sk-...
export GITHUB_TOKEN=ghp_...

# Vector databases
export CHROMA_URL=http://localhost:8000
export WEAVIATE_URL=http://localhost:8080
export WEAVIATE_API_KEY=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

---

Configuration File

Environment variables can also be set in a .env file:

# .env file
ANTHROPIC_API_KEY=sk-ant-...
GITHUB_TOKEN=ghp_...
SKILL_SEEKERS_OUTPUT=./output
SKILL_SEEKERS_RATE_LIMIT=0.5

Load with:

# Automatically loaded if python-dotenv is installed
# Or manually:
export $(cat .env | xargs)

---

Priority Order

Settings are applied in this order (later overrides earlier):

1. Default values
2. Environment variables
3. Configuration file
4. Command-line flags

Example:

# Default: rate_limit = 0.5
export SKILL_SEEKERS_RATE_LIMIT=1.0  # Env var overrides default
# Config file: rate_limit = 0.2      # Config overrides env
skill-seekers scrape --rate-limit 2.0  # Flag overrides all

---

Security Best Practices

Never commit API keys

# Add to .gitignore
echo ".env" >> .gitignore
echo "*.key" >> .gitignore

Use secret management

# macOS Keychain
export ANTHROPIC_API_KEY=$(security find-generic-password -s "anthropic-api" -w)

# Linux Secret Service (with secret-tool)
export ANTHROPIC_API_KEY=$(secret-tool lookup service anthropic)

# 1Password CLI
export ANTHROPIC_API_KEY=$(op read "op://vault/anthropic/credential")

File permissions

# Restrict .env file
chmod 600 .env

---

Troubleshooting

Variable not recognized

# Check if set
echo $ANTHROPIC_API_KEY

# Check in Python
python -c "import os; print(os.getenv('ANTHROPIC_API_KEY'))"

Priority issues

# See effective configuration
skill-seekers config --show

Path expansion

# Use full path or expand tilde
export SKILL_SEEKERS_HOME=$HOME/.skill-seekers
# NOT: ~/.skill-seekers (may not expand in all shells)
