Weft
Homebrew for AI coding agents: skills, agents & MCP
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
There's a lot of great "harness" material out there now — skill packs, spec-driven dev systems like gsd-core, agent setups — but unlike MCP, there's no shared way to distribute it. Some ship as npx, some are plugin-only, some just hand you a setup script. Multiply that by CLI fragmentation (Claude Code, Codex, Gemini, Cursor, opencode) and trying anything out becomes a chore of porting and hand-copying files.
It asks which CLI + scope once, drops pre-built, verified files into the right place, and merges config fragments into your existing JSON. The part I care most about: your machine never runs a harness's own installer — a CI step does that once in a sandbox and publishes a normalized snapshot. And every install writes a receipt, so uninstall/upgrade are exact instead of "hope you got all the files."
It's early and the catalog is still small. I'd love feedback on the model — especially the cross-CLI normalization and the receipt-based exact-uninstall — and which harnesses you'd actually want to install this way.

Hi PH 👋 I'm the maker of weft.
There's a lot of great "harness" material out there now — skill packs, spec-driven dev systems like gsd-core, agent setups — but unlike MCP, there's no shared way to distribute it. Some ship as npx, some are plugin-only, some just hand you a setup script. Multiply that by CLI fragmentation (Claude Code, Codex, Gemini, Cursor, opencode) and trying anything out becomes a chore of porting and hand-copying files.
weft does the packaging ahead of time:
It asks which CLI + scope once, drops pre-built, verified files into the right place, and merges config fragments into your existing JSON. The part I care most about: your machine never runs a harness's own installer — a CI step does that once in a sandbox and publishes a normalized snapshot. And every install writes a receipt, so uninstall/upgrade are exact instead of "hope you got all the files."
It's early and the catalog is still small. I'd love feedback on the model — especially the cross-CLI normalization and the receipt-based exact-uninstall — and which harnesses you'd actually want to install this way.
