vessel-light

vessel-light

vessel-light packages Vessel's design language for agents writing raw HTML and CSS. It has no install, build, or dependencies. Copy the .ghost/ package into a repo so your agent can select and apply Vessel's guidance, tokens, primitives, and worked compositions.

Copy

npx degit <repo>/packages/vessel-light/.ghost .ghost

Or copy it without degit:

cp -R packages/vessel-light/.ghost .ghost

Loop

ghost gather
ghost pull <selected-node> [...]
# generate HTML/CSS
ghost review

Structure

The corpus is factored by rate of change under adaptation: foundation.* nodes carry Vessel's load-bearing decisions — value-free decision logic that survives any adaptation, plus the identity dials (shape, palette, type, temperature), each stating Vessel's current answer; context.* nodes are named situations that re-tune the contract; standard.model-defaults is the model's measured shared defaults (prune lines your brand legitimately violates) and foundation.tells guards near-misses of Vessel's own signature. Every literal value lives in materials/tokens.css.

Curation

Each example says what to keep and what to change. Together they demonstrate every closed set the foundations enumerate: the emphasis ladder, text variants, tones, and elevation tiers. Regenerate examples whenever tokens or answered foundation values change. Add one when repeated work proves a gap, not because a surface might exist someday.
