End-to-end project engineering: design, incremental build, verify, debug systematically. Use when building software, dashboards, scheduled jobs, or web apps the user has asked for (e.g. build a price monitor, daily summary task, ship an API).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Phase 0: SKILL DISCOVERY & REQUIRED READING **⚠️ CRITICAL — UI Design Quality Gate:** If the project produces ANY visual HTML output (dashboard, web app, landing page, portfolio, any page the user will see), you MUST `read_file` the `ui-design` skill's SKILL.md and follow it BEFORE writing any HTML/CSS. This is not optional. project-builder handles engineering; ui-design handles visual quality (and tells you when to reach for a component library like shadcn/ui, HeroUI, or coss ui instead of hand-writing). Skipping ui-design produces generic AI slop. **A. Pick the sources and tools.** For research and API documentation, use web search. For live market numbers or external actions, reuse the relevant installed skill. Read its SKILL.md before use; search missing skills with `auto_install=false` and install only with user approval. Write custom API code only after checking that no suitable skill covers the operation; verify endpoints and response shapes against current official documentation. …

How to install
mdr add starchild-ai-agent/official-skills/project-builder@sha256:902dae1e4171d186The line at the top of this page pins the label v1.7.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
