opencode Tools

codebase-memory-mcp is an MCP server that indexes repositories into a persistent knowledge graph of functions, classes, and dependencies. It solves the problem of AI agents inefficiently reading files one-by-one, enabling structural queries with ~120x fewer tokens. It's for developers and teams using AI coding assistants like Claude Code who need fast, local, and deep codebase understanding.

Context window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.

Atlas is a native macOS editor built to manage the work around coding—research, planning, and knowledge—alongside the AI agent threads that turn them into commits. It solves the problem of fragmented workflows by providing a unified planning surface where teams of humans and multiple AI agents can collaborate efficiently. It's for developers and engineering teams who use AI coding assistants like Claude, Codex, and Gemini and want to coordinate their work in a single, local-first application.

Archify is an agent skill that transforms plain English descriptions of systems into beautiful, interactive HTML diagrams. It solves the problem of creating and maintaining accurate, up-to-date architecture, workflow, and sequence diagrams by generating them directly from conversation. It's for developers, architects, and teams who need to quickly visualize, share, and verify system designs with motion, exploration, and crisp export built-in.

Obsidian Skills is a set of tools that enables AI agents to read from and write to Obsidian vaults using its command-line interface and open formats like Markdown and JSON Canvas. It solves the problem of AI assistants being unable to directly access or manipulate personal knowledge bases, bridging the gap between conversational AI and structured note-taking. It's designed for developers, researchers, and power users who want their AI agents to seamlessly integrate with and act upon their Obsidian-based knowledge systems.

Orca is an Agent Development Environment (ADE) that lets you run and manage multiple AI coding agents like Claude Code, Codex, and OpenCode in parallel, within isolated worktrees. It solves the problem of coordinating and reviewing output from a fleet of agents by providing integrated terminals, a file editor, and git tracking to keep all branches moving. It's designed for developers and teams who want to automate and scale their coding workflows using multiple AI assistants simultaneously.
