M31A: Terminal-Native Autonomous AI Coding Agent
M31A (M31 Autonomous) is an open-source, terminal-based AI coding agent written in Go that automates an end-to-end six‑phase workflow: Initialize, Discuss, Plan, Execute, Verify, and Ship. Each run produces a verified git commit and a cross-session ledger entry. The project ships as a static, single binary with zero telemetry and supports multi‑LLM providers (OpenRouter and Zen) with automatic fallback and model‑arbitrage cost selection. Key technical features include a Bubble Tea TUI, a sandboxed five‑tool surface (Bash, FileRead, FileWrite, Glob, Grep), AutoDream context consolidation, git rollback/bisect integration, OS-native key storage, and session persistence. M31A is at v1.0.0 and available via Homebrew, install script, or GitHub source.
Open-source autonomous coding agents that complete end-to-end developer workflows can influence developer productivity and agent design patterns, but this release is a niche technical tooling update rather than industry-shifting news for AdTech/MarTech.

Key Takeaways & Evidence Grounding
- M31A is a terminal-based AI coding agent implemented in Go that follows a six-phase workflow: Initialize → Discuss → Plan → Execute → Verify → Ship.
- Every run ends with a verified git commit and a cross-session learning ledger entry; the project is at v1.0.0.
- M31A supports multi-LLM providers (OpenRouter primary, Zen secondary) with automatic fallback and a model-arbitrage scorer to select cheaper capable models.
- The toolset is deliberately small and sandboxed (Bash, FileRead, FileWrite, Glob, Grep) with a permission-gating system and security guards (SSRF protection, path traversal checks).
- The project builds to a static binary (CGO_ENABLED=0), claims zero telemetry, and is published on GitHub (github.com/eshanized/M31A) with install options including Homebrew and an install script.

Mint: AI Agent for CLI and Desktop
A developer published Mint, an open-source AI agent that runs both as a CLI autonomous coding assistant and an Electron-based desktop helper. Mint provides an "agentic" Unified Agent Loop that plans and executes tasks (web search, code search, file reads, patch application) while requiring explicit user y/n approval before running shell commands or modifying files. It supports Model Context Protocol (MCP) extensions for adding autonomous tools, works with cloud models (Gemini, Claude, GPT-4o) and local models (Ollama, LM Studio, Hugging Face), and is available on GitHub and npm. The author demonstrates installation and MCP-based plugin commands and invites community feedback. Publication date: 2026-05-13.
Build a Local Terminal AI Agent (v9)
A Dev.to tutorial (published 2026-05-24) shows how to build a terminal-based AI agent using local LLMs. The guide surveys the CLI agent ecosystem, highlights limitations of cloud-dependent tools, and provides hands-on steps: install LM Studio, run a local model (example: Nous-Hermes-2-Mistral-7B-DPO.Q4_K_M.gguf), set up an API server with Ollama, and run a Python CLI agent that calls a local OpenAI-compatible HTTP endpoint. Examples include a TerminalAIAgent implementation, tmux integration scripts, and developer tools (code search, Git helpers). The post also covers basic context-window management and points readers to a paid full guide on Gumroad for extended content.
Open-source Agentic Coding CLI AgentCode Released
A developer published AgentCode, an open-source, multi-model agentic coding CLI that autonomously reads a codebase, edits files, runs tests, and manages git via an agent loop that executes LLM-issued tool calls. The project separates concerns across three files (cli.py UI, agent.py brain, tools.py hands), uses LiteLLM as an abstraction layer to support models like Claude, GPT, Gemini and Ollama, and includes features such as streaming UX, a permission prompt for destructive actions, and cost-aware routing that classifies prompt complexity to pick cheaper or stronger models. AgentCode is available on GitHub and PyPI under the MIT license. The post documents implementation details, code snippets, and engineering lessons about context management and tool definitions.
