Agent skills framework

Composable AI skills that teach assistants structured thinking

Atoms, molecules, and refiners — versioned skill files that guide Claude Code, Cursor, and other coding assistants through design-first, architecture-guided work, instead of jumping straight to code.

ATOMSMOLECULESREFINERS

Atoms, Molecules, Refiners

Single-principle guardrails compose into multi-step workflows, tuned per project by guided-interview refiners.

Skills over prompts

Versioned, team-owned skill files in the repository beat personal prompts living on one developer's machine.

A living context layer

The .lattice/ folder accumulates standards, decisions, and review insights across every feature cycle.

Straight from the person who built it

Most AI-assisted coding skips straight to code. Lattice makes it design first, then write code you'd actually approve.

Built from a five-part martinfowler.com series, turned into skills your assistant actually runs instead of advice you have to remember to apply.
