Q-Core

Run agent workflows end-to-end, without skipping instructions. Starts in one prompt in your Claude, ChatGPT, Cursor, etc.

This repository holds Q-Core, the engine that runs QFactory workflows on your computer, and the Registry with the workflows themselves.

Quick start ↓

Start with a workflow template

Open the template's page, copy its start prompt and paste it into your agent.

Contribute

You can add your own workflow or component to the Registry, fix something in Q-Core, or suggest an idea.

1. Fork the repository and make a branch.
2. Add your files and run the local checks from the contribution guide. The rules for Registry entries are in CONTRIBUTING.md.
3. Open a pull request. The checks run automatically; before merging, we run your workflow for real.

Have an idea for a workflow? Open an issue and describe what result you want.

Quick start

With your agent

1. Open your project folder in Claude Code, Codex or Cursor.
2. Write Use qfactory.io, or copy a template's start prompt from the table above.
3. The agent connects QFactory, explains what it will do and waits for your "ok" before installing anything.

Without an agent

You need Node.js 20.3 or newer. In an empty folder this installs Q-Core and the SDD pipeline and shows its steps without running them. On Linux, use sha256sum instead of shasum -a 256.

set -eu
BASE=https://registry.qfactory.io
curl -fsS -o current.json "$BASE/current.json"
REL=$(node -p 'require("./current.json").release')
SHA=$(node -p 'require("./current.json").catalogSha256')
curl -fsS -o catalog.json "$BASE/releases/$REL/catalog.json"
[ "$(shasum -a 256 catalog.json | cut -d' ' -f1)" = "$SHA" ] || { echo "catalog check failed" >&2; exit 1; }
curl -fsS -o q-core.tgz "$BASE/releases/$REL/$(node -p 'require("./catalog.json").core.artifact')"
[ "$(shasum -a 256 q-core.tgz | cut -d' ' -f1)" = "$(node -p 'require("./catalog.json").core.artifactSha256')" ] || { echo "Q-Core check failed" >&2; exit 1; }
npm install --silent --prefix .qfactory/tools ./q-core.tgz
printf '*\n' > .qfactory/.gitignore
Q=./.qfactory/tools/node_modules/.bin/q-core
$Q install "$BASE/releases/$REL" "$SHA" sdd-pipeline 0.1.0 ./workflow.yaml
$Q run ./workflow.yaml --dry-run

You should see SUCCESS: Planned 7/7 steps. For another template, use its id and its version from catalog.json. $Q doctor checks your machine. All commands are in the reference.
