Build Loop Claude Codebuildgreatproducts/builder-osUse when building features with **Claude Code** in any codebase and the work should go through a disciplined build → review → test → fix loop. Triggers on "run the build loop", "build the next task", "continue the plan", "build this feature properly", or any request to implement work from a plan file or a direct feature prompt. Builds from the plan (or the prompt if no plan exists), runs Claude Code's `/review` (plus `/security-review` for sensitive surfaces) and fixes every issue found, tests and verifies the feature end to end, fixes anything testing surfaces, and reports back once complete. Repeats until all plan tasks are checked off.01Build Loop Codexbuildgreatproducts/builder-osUse when building features with **Codex** (OpenAI Codex CLI) in any codebase and the work should go through a disciplined build → review → test → fix loop. Triggers on "run the build loop", "build the next task", "continue the plan", "build this feature properly", or any request to implement work from a plan file or a direct feature prompt. Builds from the plan (or the prompt if no plan exists), runs Codex's `/review` on uncommitted changes and fixes every issue found, tests and verifies the feature end to end, fixes anything testing surfaces, and reports back once complete. Repeats until all plan tasks are checked off.01Build Loop Cursorbuildgreatproducts/builder-osUse when building features with **Cursor** in any codebase and the work should go through a disciplined build → review → test → fix loop. Triggers on "run the build loop", "build the next task", "continue the plan", "build this feature properly", or any request to implement work from a plan file or a direct feature prompt. Builds from the plan (or the prompt if no plan exists), runs Cursor's `/review` and fixes every issue found, tests and verifies the feature end to end, fixes anything testing surfaces, and reports back once complete. Repeats until all plan tasks are checked off.01Build Mvpbuildgreatproducts/builder-osUse inside a product repository when the user wants the full MVP built from their BuilderOS spec documents. Triggers on phrases like "build my MVP", "build the app", "execute the roadmap", "start the build", "work through the whole roadmap", "build everything", or any request to implement the entire plan rather than a single task or phase. Requires `docs/prd.md` and `docs/product-roadmap.md` (plus `docs/product-vision.md` and `docs/design.md` for context). Works through every roadmap task in order — implementing, testing, and verifying each before moving on, marking checkboxes and updating the status line — and runs until all tasks are complete and the magic moment works end to end, then initializes git with an initial commit and offers to connect a remote repo.01Design Betterbuildgreatproducts/builder-osUse when the user is building or refactoring UI in their product codebase and wants designer-quality frontend code — not just functional code. Triggers on phrases like "design better", "make this UI feel more designed", "elevate the design quality", "build this with design best practices", "follow UX heuristics", "make this feel professional", "apply design polish", "review this for craft", or any request to apply UX/UI craft heuristics to code generation or review. Pairs with `docs/design.md` when it exists — the design system file owns **style** (colors, typography, spacing tokens, components), this skill owns **craft** (hierarchy, interaction, accessibility, motion, polish). Reference `docs/design.md` tokens by name for every visual decision; apply the 50-item heuristics catalogue and the Laws of UX catalogue below for every craft decision. When `docs/design.md` is absent, fall back to the codebase's existing design conventions and recommend the **Design System** skill. When a heuristic implies a token the design system doesn't have, flag it as a New Pattern to add via the **Design System** skill — never invent a value inline. Fully standalone.01Design Systembuildgreatproducts/builder-os|01Idea Generatorbuildgreatproducts/builder-os|01Idea Validatorbuildgreatproducts/builder-os|01Launch Checklistbuildgreatproducts/builder-osUse when the user's product is built (or nearly built) and they want to get it live and accessible to customers. Triggers on phrases like "create my launch checklist", "how do I deploy this", "help me launch", "get this live", "put this in production", "ship it to customers", "what do I need to do to go live", or any request for a step-by-step path from working code to a product customers can use. Audits the current codebase — stack, services, environment variables, payments, deploy config — then writes a plain-English, step-by-step launch guide to `docs/launch-checklist.md`. Every step is marked as something the user must do themselves, something their coding agent can do, or both together, and all technical terms are explained for non-technical founders.01Plaidbuildgreatproducts/plaid|020Product Plannerbuildgreatproducts/builder-os|07
