# =============================================================================
# OpenClaude Environment Configuration
# =============================================================================
# Copy this file to .env and fill in your values:
#   cp .env.example .env
#
# Only set the variables for the provider you want to use.
# All other sections can be left commented out.
# =============================================================================

# =============================================================================
# SYSTEM-WIDE SETUP (OPTIONAL)
# =============================================================================
# Instead of using a .env file per project, you can set these variables
# system-wide so OpenClaude works from any directory on your machine.
#
# STEP 1: Pick your provider variables from the list below.
# STEP 2: Set them using the method for your OS (see further down).
#
# ── Provider variables ───────────────────────────────────────────────
#
#   Option 1 — Anthropic:
#     ANTHROPIC_API_KEY=sk-ant-your-key-here
#     ANTHROPIC_MODEL=claude-sonnet-4-5              (optional)
#     ANTHROPIC_BASE_URL=https://api.anthropic.com   (optional)
#
#   Option 2 — OpenAI:
#     CLAUDE_CODE_USE_OPENAI=1

#
#   Option 4 — GitHub Models:
#     CLAUDE_CODE_USE_GITHUB=1
#     GITHUB_TOKEN=ghp_your-token-here
#
#   Option 5 — Ollama (local):
#     CLAUDE_CODE_USE_OPENAI=1
#     OPENAI_BASE_URL=http://localhost:11434/v1
#     OPENAI_API_KEY=ollama
#     OPENAI_MODEL=llama3.2
#
#   Option 6 — LM Studio (local):
#     CLAUDE_CODE_USE_OPENAI=1
#     OPENAI_BASE_URL=http://localhost:1234/v1
#     OPENAI_MODEL=your-model-id-here
#     OPENAI_API_KEY=lmstudio                        (optional)
#
#   Option 7 — AWS Bedrock (may also need: aws configure):
#     CLAUDE_CODE_USE_BEDROCK=1
#     AWS_REGION=us-east-1
#     AWS_DEFAULT_REGION=us-east-1
#     AWS_BEARER_TOKEN_BEDROCK=your-bearer-token-here
#     ANTHROPIC_BEDROCK_BASE_URL=https://bedrock-runtime.us-east-1.amazonaws.com
#
#   Option 8 — Google Vertex AI:
#     CLAUDE_CODE_USE_VERTEX=1
#     ANTHROPIC_VERTEX_PROJECT_ID=your-gcp-project-id
#     CLOUD_ML_REGION=us-east5
#     GOOGLE_CLOUD_PROJECT=your-gcp-project-id
#
# ── How to set variables on each OS ──────────────────────────────────
#
# macOS (zsh):
#   1. Open:  nano ~/.zshrc
#   2. Add each variable as:  export VAR_NAME=value
#   3. Save and reload:  source ~/.zshrc
#
# Linux (bash):
#   1. Open:  nano ~/.bashrc
#   2. Add each variable as:  export VAR_NAME=value
#   3. Save and reload:  source ~/.bashrc
#
# Windows (PowerShell):
#   Run for each variable:
#     [System.Environment]::SetEnvironmentVariable('VAR_NAME', 'value', 'User')
#   Then restart your terminal.
#
# Windows (Command Prompt):
#   Run for each variable:
#     setx VAR_NAME value
#   Then restart your terminal.
#
# Windows (GUI):
#   Settings > System > About > Advanced System Settings >
#   Environment Variables > under "User variables" click New,
#   then add each variable.
#
# ── Important notes ──────────────────────────────────────────────────
#
# LOCAL SERVERS: If using LM Studio or Ollama, the server MUST be
# running with a model loaded before you launch OpenClaude —
# otherwise you'll get connection errors.
#
# SWITCHING PROVIDERS: To temporarily switch, unset the relevant
# variables in your current terminal session:
#
#   macOS / Linux:
#     unset VAR_NAME
#     # e.g.: unset CLAUDE_CODE_USE_OPENAI OPENAI_BASE_URL OPENAI_MODEL
#
#   Windows (PowerShell — current session only):
#     Remove-Item Env:VAR_NAME
#
#   To permanently remove a variable on Windows:
#     [System.Environment]::SetEnvironmentVariable('VAR_NAME', $null, 'User')
#
# LOAD ORDER:
#   Shell and system environment variables are inherited by the process.
#   Project .env files are only used if your launcher or shell loads them
#   before starting OpenClaude.
# COMPATIBILITY:
#   System-wide variables work regardless of how you run OpenClaude:
#   npx, global npm install, bun run, or node directly. Any process
#   launched from your terminal inherits your shell's environment.
#
# REMINDER: Make sure .env is in your .gitignore to avoid committing secrets.

# Legacy aliases also work: deepseek-chat and deepseek-reasoner
# For Z.AI GLM Coding Plan, set:
# OPENAI_BASE_URL=https://api.z.ai/api/coding/paas/v4
# OPENAI_MODEL=GLM-5.1
# Optional: OPENAI_MODEL=GLM-5-Turbo, GLM-4.7, or GLM-4.5-Air
# For Hicap, use the OpenAI-compatible route flag above and set:
# HICAP_API_KEY=your-hicap-key-here
# OPENAI_BASE_URL=https://api.hicap.ai/v1
# OPENAI_MODEL=claude-opus-4.7

# Use a custom OpenAI-compatible endpoint (optional — defaults to api.openai.com)
# OPENAI_BASE_URL=https://api.openai.com/v1
# Choose the OpenAI-compatible API surface (optional — defaults to chat_completions)
# Supported: chat_completions, responses
# OPENAI_API_FORMAT=chat_completions
# Choose a custom auth header for OpenAI-compatible providers (optional).
# Authorization defaults to Bearer; custom headers default to the raw API key.
# Set OPENAI_AUTH_HEADER_VALUE when the header value differs from OPENAI_API_KEY.
# OPENAI_AUTH_HEADER=api-key
# OPENAI_AUTH_SCHEME=raw
# OPENAI_AUTH_HEADER_VALUE=your-header-value-here

# Fallback context window size (tokens) when the model is not found in
# integration model metadata (default: 128000). Increase this for models with larger
# context windows (e.g. 200000 for Claude-sized contexts).
# CLAUDE_CODE_OPENAI_FALLBACK_CONTEXT_WINDOW=128000

# Per-model context window overrides as a JSON object.
# Takes precedence over integration model metadata, so you can register new or
# custom models without patching source.
# Example: CLAUDE_CODE_OPENAI_CONTEXT_WINDOWS={"my-corp/llm-v3":262144,"gpt-4o-mini":128000}
# CLAUDE_CODE_OPENAI_CONTEXT_WINDOWS=

# Per-model maximum output token overrides as a JSON object.
# Use this alongside CLAUDE_CODE_OPENAI_CONTEXT_WINDOWS when your model
# supports a different output limit than what integration metadata specifies.
# Example: CLAUDE_CODE_OPENAI_MAX_OUTPUT_TOKENS={"my-corp/llm-v3":8192}
# CLAUDE_CODE_OPENAI_MAX_OUTPUT_TOKENS=

# -----------------------------------------------------------------------------
# Option 6: LM Studio (local models)
# -----------------------------------------------------------------------------
# LM Studio exposes an OpenAI-compatible API, so we use the OpenAI provider.
# Make sure LM Studio is running with the Developer server enabled
# (Developer tab > toggle server ON).
#
# Steps:
#   1. Download and install LM Studio from https://lmstudio.ai
#   2. Search for and download a model (e.g. any coding or instruct model)
#   3. Load the model and start the Developer server
#   4. Set OPENAI_MODEL to the model ID shown in LM Studio's Developer tab
#
# The default server URL is http://localhost:1234 — change the port below
# if you've configured a different one in LM Studio.
#
# OPENAI_API_KEY is optional — LM Studio runs locally and ignores it.
# Some clients require a non-empty value; if you get auth errors, set it
# to any dummy value (e.g. "lmstudio").
#
# CLAUDE_CODE_USE_OPENAI=1
# OPENAI_BASE_URL=http://localhost:1234/v1
# OPENAI_MODEL=your-model-id-here

# CLAUDE_CODE_USE_OPENAI=1
# MINIMAX_API_KEY=your-minimax-key-here
# OPENAI_BASE_URL=https://api.minimax.io/v1
# OPENAI_MODEL=MiniMax-M2.5


# =============================================================================
# OPTIONAL TUNING
# =============================================================================

# Max number of API retries on failure (default: 10)
# CLAUDE_CODE_MAX_RETRIES=10

# Enable persistent retry mode for unattended/CI sessions
# Retries 429/529 indefinitely with smart backoff
# CLAUDE_CODE_UNATTENDED_RETRY=1

# Enable extended key reporting (Kitty keyboard protocol)
# Useful for iTerm2, WezTerm, Ghostty if modifier keys feel off
# OPENCLAUDE_ENABLE_EXTENDED_KEYS=1

# Disable "Co-authored-by" line in git commits made by OpenClaude
# OPENCLAUDE_DISABLE_CO_AUTHORED_BY=1

# Disable strict tool schema normalization for non-Gemini providers
# Useful when MCP tools with complex optional params (e.g. list[dict])
# trigger "Extra required key ... supplied" errors from OpenAI-compatible endpoints
# OPENCLAUDE_DISABLE_STRICT_TOOLS=1

# Disable hidden <system-reminder> messages injected into tool output
# Suppresses the file-read cyber-risk reminder and the todo/task tool nudges
# Useful for users who want full transparency over what the model sees
# OPENCLAUDE_DISABLE_TOOL_REMINDERS=1

# Log structured per-request token usage (including cache metrics) to stderr.
# Useful for auditing cache hit rate / debugging cost spikes outside the REPL.
# Any truthy value enables it ("verbose", "1", "true").
#
# Complements (does NOT replace) CLAUDE_CODE_ENABLE_TOKEN_USAGE_ATTACHMENT —
# they serve different audiences:
#   - OPENCLAUDE_LOG_TOKEN_USAGE is user-facing: one JSON line per API
#     request on stderr, intended for humans inspecting cost/caching.
#   - CLAUDE_CODE_ENABLE_TOKEN_USAGE_ATTACHMENT is model-facing: injects
#     a context-usage attachment INTO the prompt so the model can reason
#     about its own remaining context. Does not touch stderr.
# Turn on whichever audience you're debugging; both can run together.
# OPENCLAUDE_LOG_TOKEN_USAGE=verbose

# Custom timeout for API requests in milliseconds (default: varies)
# API_TIMEOUT_MS=60000

# Enable debug logging
# CLAUDE_DEBUG=1


# =============================================================================
# WEB SEARCH (OPTIONAL)
# =============================================================================
# OpenClaude includes a web search tool. By default it uses DuckDuckGo (free)
# or the provider's native search (Anthropic firstParty / vertex).
#
# Set one API key below to enable a provider. That's it.

# ── Provider API keys — set ONE of these ────────────────────────────

# Tavily (AI-optimized search, recommended)
# TAVILY_API_KEY=tvly-your-key-here

# Exa (neural/semantic search)
# EXA_API_KEY=your-exa-key-here

# You.com (RAG-ready snippets)
# YOU_API_KEY=your-you-key-here

# Jina (s.jina.ai endpoint)
# JINA_API_KEY=your-jina-key-here

# Brave (independent web index, generous free tier)
# BRAVE_API_KEY=your-brave-key-here

# Bing Web Search
# BING_API_KEY=your-bing-key-here

# Mojeek (privacy-focused)
# MOJEEK_API_KEY=your-mojeek-key-here

# Linkup
# LINKUP_API_KEY=your-linkup-key-here

# Firecrawl (premium, uses @mendable/firecrawl-js)
# FIRECRAWL_API_KEY=fc-your-key-here

# Self-hosted Firecrawl endpoint (optional — omit to use cloud API)
# FIRECRAWL_API_URL=https://your-firecrawl-instance.com

# ── Provider selection mode ─────────────────────────────────────────
#
# WEB_SEARCH_PROVIDER controls fallback behavior:
#
#   "auto"      (default) — try all configured providers, fall through on failure
#   "custom"    — custom API only, throw on failure (NOT in auto chain)
#   "firecrawl" — firecrawl only
#   "tavily"    — tavily only
#   "exa"       — exa only
#   "you"       — you.com only
#   "jina"      — jina only
#   "brave"     — brave only
#   "bing"      — bing only
#   "mojeek"    — mojeek only
#   "linkup"    — linkup only
#   "ddg"       — duckduckgo only
#   "native"    — anthropic native / codex only
#
# Auto mode priority: firecrawl → tavily → exa → you → jina → brave → bing →
#                     mojeek → linkup → ddg
# Note: "custom" is NOT in the auto chain. To use the custom API provider,
# you must explicitly set WEB_SEARCH_PROVIDER=custom.
#
# WEB_SEARCH_PROVIDER=auto

# ── Built-in custom API presets ─────────────────────────────────────
#
# Use with WEB_KEY for the API key:
# WEB_PROVIDER=searxng|google|brave|serpapi
# WEB_KEY=your-api-key-here
#
# Google Custom Search additionally requires the Programmable Search Engine ID:
# WEB_PROVIDER=google
# WEB_KEY=your-google-api-key
# GOOGLE_CSE_ID=your-programmable-search-engine-id
#
# Note: Google's Custom Search JSON API is closed to new customers and is
# scheduled for sunset on 2027-01-01. Prefer BRAVE_API_KEY / TAVILY_API_KEY
# / EXA_API_KEY for new setups.

# ── Custom API endpoint (advanced) ──────────────────────────────────
#
# WEB_SEARCH_API    — base URL of your search endpoint
# WEB_QUERY_PARAM         — query parameter name (default: "q")
# WEB_METHOD        — GET or POST (default: GET)
# WEB_PARAMS        — extra static query params as JSON: {"lang":"en","count":"10"}
# WEB_URL_TEMPLATE  — URL template with {query} for path embedding
# WEB_BODY_TEMPLATE — custom POST body with {query} placeholder
# WEB_AUTH_HEADER   — header name for API key (default: "Authorization")
# WEB_AUTH_SCHEME   — prefix before key (default: "Bearer")
# WEB_HEADERS       — extra headers as "Name: value; Name2: value2"
# WEB_JSON_PATH     — dot-path to results array in response

# ── Custom API security guardrails ──────────────────────────────────
#
# The custom provider enforces security guardrails by default.
# Override these only if you understand the risks.
#
# WEB_CUSTOM_TIMEOUT_SEC=15                  — request timeout in seconds (default 15)
# WEB_CUSTOM_MAX_BODY_KB=300                 — max POST body size in KB (default 300)
# WEB_CUSTOM_ALLOW_ARBITRARY_HEADERS=false   — set "true" to use non-standard headers
# WEB_CUSTOM_ALLOW_HTTP=false                — set "true" to allow http:// URLs
# WEB_CUSTOM_ALLOW_PRIVATE=false             — set "true" to target localhost/private IPs
#                                               (needed for self-hosted SearXNG)
