Show HN: Z, minimal agentic harness for engineers that just works

A developer released Z, a minimal agentic coding harness for the terminal that supports 26 providers via LiteLLM, including Z.AI, DeepSeek, Anthropic, OpenAI, Ollama, Bedrock, Copilot OAuth, and OpenRouter, with features like live token streaming, Telegram remote control, context compaction strategies, and 19 built-in tools. The tool is MIT-licensed, requires no subscription, and allows hot-swapping models mid-session with commands like `/providers use`.

An agentic coding harness for the terminal. Bring your own API keys — hot-swap models mid-session with /providers use . No subscriptions. pip install -e . z --install one-time setup wizard z Config lives in ~/.z.json : { "api url": "https://api.z.ai/api/paas/v4/", "api key": "sk-...", "model": "glm-4.7" } 26 providers, one client — Z.AI, DeepSeek, Anthropic, OpenAI, Ollama, Bedrock, Copilot OAuth, OpenRouter, all via LiteLLM. Constant streaming — every token, including reasoning, streams live. No spinners. Telegram remote — z --telegram <token and drive the agent from your phone. Context that survives compaction — half/quarter/lastTwo strategies, todo persistence, tool-result caching. Claude Code semantics — CLAUDE.md, hooks, persistent memory, cron tasks, sub-agents, MCP. 19 built-in tools — file ops, shell, search, web search, image analysis, background processes. | Command | What | |---|---| /providers use <name | Switch models mid-session | /compact | Force context compaction | /cost | Token usage and spend | /todo | Todo panel | cmd | Run shell command | Ctrl+T | Toggle reasoning effort | Plugins: drop a .py in ~/.z/plugins/ .
