## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI

## SKI

SKI is a voice-first coding harness that runs on your Mac. Its premise is that coding agents are now fast enough that the real constraint is human attention: five agents working in parallel still have one pair of eyes reviewing them, and output has outpaced anyone's ability to read it. SKI's answer is to make the interface conversational, so you find out what your agents did by listening rather than reading, and acknowledge them in about the time a spoken reply takes.

The harness sits above agents rather than replacing them. It runs Claude Code, Codex, Cursor, OpenCode, Antigravity and others side by side, each on its own task, using the accounts you already pay for. Because it isn't tied to any model vendor, you can send hard reasoning to an expensive engine and bulk work to a cheap open-weight one. An orchestration layer keeps the context of every project, branch and chat, so you can ask where things stand and get one spoken answer — and chain agents together, such as having one plan a feature and another build it.

Git integration is built in: every chat gets its own branch and isolated worktree, live diffs are visible as agents work, and you can open a pull request by voice. Safety is treated as a design requirement rather than an add-on — SKI reconstructs the instruction it believes you meant from project context, shows it for review before the agent sees it, and asks for confirmation on anything irreversible. Your projects, code and chats stay on your Mac and run on your own agent accounts, while voice audio passes through the cloud for understanding but isn't stored. Pricing keeps text usage free forever, with credits spent only on real-time voice.

**Pricing & Plans:** SKI is free forever for text: unlimited typed chats with every supported agent and project on the Free plan. Voice is credit-based — Free includes 300 voice credits/month and 2 concurrent voice sessions, Pro is $20/month with 2,000 credits and 12 sessions, and Enterprise offers custom team rates. Top-up credits last 12 months.

- **Hands-free voice loop:** Talk to your agents and hear spoken replies in real time, so you can ask for a change, hear the result and answer the follow-up without returning to the keyboard.
- **Cross-project orchestration:** SKI keeps project, branch and chat context across every project, and hands each job to the right agent when you ask where things stand.
- **Git built in:** Each chat gets its own branch and worktree so parallel agents never collide; watch live diffs and open a pull request by voice.
- **Multiple agents, one hub:** Run Claude Code, Codex, Antigravity, OpenCode and others simultaneously, each on its own task, with a notification the moment one needs you.
- **Multilingual commands:** Speak in your own language or mix two; SKI interprets the intent and converts it into a precise instruction for the agent.

**Strengths:** Neutral harness that works with the agent subscriptions you already pay for; Unlimited text usage free forever, with credits only spent on voice; Real-time spoken talkback instead of reading logs; Git branches, worktrees and PRs handled by voice
