Table of Contents

Overview

Skill Seekers uses environment variables for:

  • API authentication (Claude, Gemini, OpenAI, GitHub)
  • Configuration paths
  • Output directories
  • Behavior customization
  • Debug settings

Variables are read at runtime and override default settings.

API Keys

ANTHROPIC_API_KEY

Purpose: Claude AI API access for enhancement and upload.

Format: sk-ant-api03-...

Used by:

  • skill-seekers enhance (API mode)
  • skill-seekers upload (Claude target)
  • AI enhancement features

Example:

export ANTHROPIC_API_KEY=sk-ant-api03-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Alternative: Use --api-key flag per command.

GOOGLE_API_KEY

Purpose: Google Gemini API access for upload.

Format: AIza...

Used by:

  • skill-seekers upload (Gemini target)

Example:

export GOOGLE_API_KEY=AIzaSyxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

OPENAI_API_KEY

Purpose: OpenAI (and OpenAI-compatible) API access for enhancement, upload, and embeddings.

Format: sk-...

Used by:

  • skill-seekers create / scan / enhance (AI enhancement, API mode)
  • skill-seekers upload (OpenAI target)
  • Embedding generation for vector DBs

Example:

export OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Combine with OPENAI_BASE_URL + OPENAI_MODEL to route enhancement through any OpenAI-compatible provider (OpenRouter, Groq, Cerebras, Mistral, NVIDIA NIM). See LLM Provider Selection.

MOONSHOT_API_KEY

Purpose: Moonshot AI (Kimi) API access for enhancement (API mode).

Format: sk-...

Used by:

  • skill-seekers create / scan / enhance (enhancement, Kimi/Moonshot)

Example:

export MOONSHOT_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

GITHUB_TOKEN

Purpose: GitHub API authentication for higher rate limits, plus authoring community-registry submissions.

Format: ghp_... (personal access token) or github_pat_... (fine-grained)

Used by:

  • skill-seekers create (GitHub repos)
  • skill-seekers create --config (unified multi-source)
  • skill-seekers scan (local codebases)
  • skill-seekers scan — required to submit AI-generated configs to the community registry (the scan itself runs without it; the publish prompt is just skipped with a hint)

Benefits:

  • 5000 requests/hour vs 60 for unauthenticated
  • Access to private repositories
  • Higher GraphQL API limits
  • Enables opening community-config GitHub issues from scan

Example:

export GITHUB_TOKEN=ghp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Create token: https://github.com/settings/tokens

Platform Configuration

ANTHROPIC_BASE_URL

Purpose: Custom Claude API endpoint.

Default: https://api.anthropic.com

Use case: Proxy servers, enterprise deployments, regional endpoints.

Example:

export ANTHROPIC_BASE_URL=https://custom-api.example.com

OPENAI_BASE_URL

Purpose: Custom OpenAI-compatible API endpoint for enhancement.

Default: https://api.openai.com/v1

Use case: Any OpenAI-compatible provider — OpenRouter, Groq, Cerebras, Mistral, NVIDIA NIM, local servers (Ollama, vLLM, LM Studio), proxies.

Example:

export OPENAI_BASE_URL=https://openrouter.ai/api/v1

Read automatically by the OpenAI SDK. Pair with OPENAI_API_KEY and OPENAI_MODEL.

LLM Provider Selection

The AI enhancement step (create, scan, enhance) supports multiple providers through one abstraction. The provider is chosen by the first API key found, in this order: ANTHROPIC_API_KEY → ANTHROPIC_AUTH_TOKEN → MOONSHOT_API_KEY → GOOGLE_API_KEY → OPENAI_API_KEY. If none is set, it falls back to LOCAL agent mode (--agent, no API key required — uses your Claude Pro / ChatGPT Plus subscription).

Any OpenAI-compatible provider (OpenRouter, Groq, Cerebras, Mistral, NVIDIA NIM)

export OPENAI_API_KEY="<provider key>"
export OPENAI_BASE_URL="https://api.groq.com/openai/v1"   # provider endpoint
export OPENAI_MODEL="llama-3.3-70b-versatile"             # a model that provider offers
skill-seekers create <source>
ProviderOPENAI_BASE_URL
OpenRouterhttps://openrouter.ai/api/v1
Groqhttps://api.groq.com/openai/v1
Cerebrashttps://api.cerebras.ai/v1
Mistralhttps://api.mistral.ai/v1
NVIDIA NIMhttps://integrate.api.nvidia.com/v1

Set OPENAI_MODEL — the OpenAI default (gpt-4o) won't exist on other providers. Ensure no higher-priority key (e.g. ANTHROPIC_API_KEY) is set, or it wins.

Subscriptions instead of API credits (LOCAL mode)

skill-seekers create <source> --agent codex    # ChatGPT Plus via Codex CLI
skill-seekers create <source> --agent claude   # Claude Pro/Max via Claude Code

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

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 create --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)
