product-primitives skillA

product-primitives is agent-read markdown (skill) from teambrilliant/dev-skills: Break down complex products, features, or systems into fundamental primitives and building blocks from a software creator's perspective. Use when starting a new application, designing a large feature, or needing to understand a complex system's moving parts before building. Trigger phrases: "break down X", "decompose this", "what are the primitives", "building blocks of Z", "map the architecture", "what are the moving parts", "analyze this system", or any situation where you need to identify the.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.

What the file says

# Product Primitives

Break complex systems into fundamental primitives — deep, information-hiding building blocks with clear boundaries and simple interfaces. Think from the software creator's perspective: what are the atomic capabilities this system needs, how do they connect, and where should the boundaries be?

## When to Use

One-off analysis for big-picture thinking — new applications, large features, or understanding existing system architecture. While `/dev-skills:product-thinker` thinks from the user's perspective, product primitives thinks from the builder's perspective, identifying where to draw module boundaries and what each piece should encapsulate.

Use `Explore` sub-agents to research the codebase if working in an existing project. Use browser (Chrome DevTools MCP) to walk through the product if it's running.

## How to Decompose

The quality of a decomposition depends on where you draw boundaries. Use these principles to guide every boundary decision:

### Deep, not shallow

How to install

Latest version
mdr add teambrilliant/dev-skills/product-primitives@git:20260507.c5d07e6
Exact content
mdr add teambrilliant/dev-skills/product-primitives@sha256:9b71e86def70a0ef

Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
