Lattice

Composable AI skills that teach assistants structured thinking — design-first, context-aware, and architecture-guided.

What is Lattice?

AI coding assistants jump straight to code, silently make design decisions, forget constraints mid-conversation, and produce output nobody reviewed against real standards. Lattice fixes this with composable skills in three tiers — atoms, molecules, refiners — that embed battle-tested engineering disciplines plus a living context layer that accumulates your project's standards, decisions, and review insights across every feature cycle.

Three principles guided Lattice's design:

Skills over prompts — versioned, team-owned skill files in the repository beat personal prompts on one developer's machine
Composability over monoliths — small single-purpose skills that combine into workflows beat one instruction document that tries to cover everything
Living context over static config — the .lattice/ folder grows smarter with every feature cycle rather than being configured once and forgotten

The Three Tiers

Tier	Purpose
Atoms	Single-principle guardrails — clean code, architecture, DDD, secure coding, test quality, design-first, and more
Molecules	Multi-step workflows that compose atoms — design, implement, refactor, fix, review
Refiners	Guided interviews that produce project-specific standards, customizing how atoms behave for your team

The Pipeline

Skills form a delivery lifecycle: requirement-forge → design-blueprint → code-forge → review, with refactor-safely and bug-fix covering structural and defect-driven work. requirement-forge starts the pipeline — it acts as a senior PM + BA pair to produce structured feature specs in .lattice/requirements/ that feed directly into design-blueprint. For teams with existing codebases, architecture-compass sits before the pipeline — it scans the repository, runs a structured interview, and produces an agreed architectural direction that orients the team before any code changes begin. Each stage consumes and produces artifacts in .lattice/, growing the living context layer.

Feature Lifecycle Pipeline

Getting Started

Install Lattice — choose the path that fits your setup:

Option A — Claude Code plugin (also works in Cursor — reads Claude Code skills automatically)
```
/plugins marketplace add techygarg/lattice
/plugins install lattice
/reload-plugins
```
Option B — Codex-compatible plugin package
```
codex plugin marketplace add techygarg/lattice
codex plugin add lattice@lattice
codex plugin list | rg -i lattice
```
The Codex plugin package lives in plugins/lattice/ and is registered by .agents/plugins/marketplace.json. It contains the same 26 skills flattened for Codex discovery.

This duplication currently to support codex. In future, we may find a better approach as tools evolves.

Option C — Clone and install locally (any AI tool)
```
git clone https://github.com/techygarg/lattice.git
cd lattice
./tools/install.sh /absolute/path/to/your/skills/folder
```
Pass the skills directory for your tool: ~/.claude/skills/ for Claude Code, .cursor/skills/ for Cursor, or any tool's skills folder.

Try it immediately. The repo includes sample/ — a realistic .NET 8 User Service spec with requirements, domain concepts, and constraints already written. Copy the sample/ folder contents into any empty directory and follow the steps below.
Run /lattice-init in your AI tool's chat — scans the project, suggests refiners in priority order, creates .lattice/config.yaml. All skill commands (/lattice-init,/requirement-forge, /design-blueprint, /code-forge, etc.) are typed in the AI chat, not the terminal.
Spec (optional but recommended) — /requirement-forge acts as a senior PM + BA pair to define epics and feature specs before any design begins. Accepts existing PRDs, feature lists, or a verbal description. Produces .lattice/requirements/ as direct input to design-blueprint.
Design — /design-blueprint walks through five progressive design levels before any code is written.
Implement — /code-forge generates implementation from the approved blueprint, applying all quality atoms.
Review — /review audits the change and persists insights into .lattice/ for the next cycle.
