Pi Go

Pi Go (pi-go) is a coding agent for the terminal, written in Go on Agent Development Kit (ADK) for Go and distributed as a single binary. It works against Claude, GPT and O-series, Gemini, Mistral, Grok, Azure OpenAI, OpenRouter, OpenCode, and Ollama models (local or cloud), and switches provider mid-conversation with a slash command. Named model roles (default, smol, slow, plan, and commit) pick a fast, capable, or planning-oriented model per task.

Requests flow from the CLI to the agent, the model provider, and sandboxed tool calls, then back to a Bubble Tea terminal UI. File read, write, and edit, shell, grep, find, tree, and git tools are all restricted to the project directory. A language-server client for Go, TypeScript and JavaScript, Python, Rust, and Java adds formatting and diagnostics hooks, and git tools generate conventional commits from the diff.

Sessions persist as append-only JSONL event logs that can be branched, compacted, and resumed. A process-based subagent system runs explore, plan, designer, reviewer, and task agents concurrently, and a Plan-Driven Development mode turns a planning session into a spec that a task agent executes. Memory Palace gives the agent memory across sessions in four layers (identity, essential story, on-demand recall, and semantic or keyword search) backed by SQLite, embeddings, and a temporal knowledge graph.

It extends through hooks, skills, and MCP servers, and installs skill bundles from plugin marketplaces in the format other coding agents use, such as the Superpowers marketplace. An audit command scans skill files for hidden Unicode, BiDi tricks, and other supply-chain threats. Pi Go also runs as an Agent Client Protocol (ACP) server for editors such as Zed and JetBrains IDEs, and as a JSON-RPC server for other editor integrations.
