Weft

weft is a package manager for "harnesses" — bundles of skills, subagents, slash commands, hooks, and MCP servers that upgrade what your AI coding agent can do. What makes it different: • One catalog targets Claude Code, Codex, Gemini, Cursor & opencode install the same harness on any CLI, no porting. • Your machine never runs a harness's installer. CI builds & verifies each one in a sandbox; weft just places files + merges config. npm install -g @symploke-ai/weft weft install gsd-core
