Hadamard — Development skill for Claude Code

Development community

Hadamard is an independent, experimental agent for practical multi-tool, multi-session, and bridge-assisted agent workflows, learned from the outstanding and valuable experience of Claude code, codex.

LLM harnesses are powerful but hard to manage on real engineering and research work — shipping software, running AI-for-Science (AI4S) pipelines, training neural networks and steering experiments. Contexts overflow, tool calls sprawl, runs drift from the plan, and a single agent loop never gets a second opinion.

**Hadamard** exists to make agent engineering and research controllable. Multiple agents on different providers talk to each other — investigating, reviewing, and dispatching in parallel — so problems get considered more thoroughly. One TypeScript runtime provides tools, skills, durable sessions, memory, and MCP, plus a bridge that manages installed agent CLIs (Claude Code, Codex, Cursor, Pi, CodeWhale, Reasonix, Crush) as child processes; the same runtime ships with a terminal UI and a desktop GUI.

Inspired by Claude Code, Codex, Deepagents, and the broader agent ecosystem. Hadamard remains independent with its own public API and documentation.
