# hyclaude — launch Claude Code on Tencent TokenHub's Anthropic-compatible API.
#
# Tencent TokenHub is a multi-model aggregator — one subscription gives access
# to Hunyuan (HY3), DeepSeek, GLM, Kimi, MiniMax, Qwen, and more.
#
# Endpoint:
#   - Token Plan (recommended): https://api.lkeap.cloud.tencent.com/plan/anthropic
#   - Coding Plan:              https://api.lkeap.cloud.tencent.com/coding/anthropic
#
# Reads HY_API_KEY from the environment first, then falls back to
# ~/.zshrc / ~/.bashrc / ~/.bash_profile / ~/.profile if not already exported.
#
# Quick start (no install needed):
#   chmod +x hyclaude
#   ./hyclaude
#
# Optional — make it globally available:
#   sudo mv hyclaude /usr/local/bin/ && sudo chmod +x /usr/local/bin/hyclaude
#
# Use:
#   hyclaude                  # hy3-preview (Tencent default)
#   hyclaude fast             # hy-mt2-lite (cheap / fast)
#   hyclaude deepseek         # deepseek-v4-pro
#   hyclaude kimi             # kimi-k2.7-code
#   hyclaude glm              # glm-5.2
#   hyclaude minimax          # minimax-m3
#   hyclaude qwen             # qwen3.5-plus
#   hyclaude long             # request max context window
#   hyclaude effort max       # set reasoning effort (low|medium|high|xhigh|max)
#   hyclaude update           # git pull latest from this repo
#   hyclaude --help           # any remaining flag is forwarded to claude
#
# Optional env overrides:
#   HY_MODEL=hy3-preview                      # main model (any model on TokenHub)
#   HY_FLASH_MODEL=hy-mt2-lite                # flash / haiku / subagent tier
#   HY_BASE_URL=https://.../anthropic          # custom Anthropic-compatible base URL
#   HY_CTX=1048576                            # max context tokens
#   HY_OUTPUT=8000                            # cap output tokens
#   HY_EFFORT=max                             # CLAUDE_CODE_EFFORT_LEVEL
