designbook/
Local mirror of the whynot Claude Design project (the atelier — source of truth
for the visual language). This directory is written and read by the /design-sync
skill (the DesignSync tool over the claude.ai login). It is not edited by the
build scripts; tokens/ and src/styles/ in the repo root are derived from it.
See DesignSystemIntroduction.md §1 (three places) and §5 (the atelier → repo hop),
and RecentChanges.md (regenerated by make designbook-sync) for the last diff.
How it syncs
The designbook is a cloud project of type PROJECT_TYPE_DESIGN_SYSTEM. Sync is
two-way and incremental — one component at a time, never a wholesale replace:
/design-sync # in Claude Code: pull the project into this
# directory (or push built UI back to the canvas)
node scripts/designbook-sync.mjs --mark-synced # stamp when the pull happened
make designbook-sync # record what changed + last-sync time → RecentChanges.md
Freshness marker — .design-sync.json
make designbook-sync only reflects the latest design if /design-sync has been run.
It cannot pull on its own (the pull is an agent step), so freshness is tracked in
.design-sync.json:
{ "lastSyncAt": "<ISO>", "remoteUpdatedAt": "<ISO>", "projectId": "…", "projectName": "…" }
--mark-synced(run right after/design-sync) setslastSyncAtto now.RecentChanges.mdand themakeoutput then show "Last /design-sync: <datetime>".- To detect that the cloud moved ahead, run
make designbook-check— backed by llm-connect. It uses theclaude-codeadapter to ask the localclaudebinary for the project's currentupdatedAtviaDesignSync.list_projects, then records it withnode scripts/designbook-sync.mjs --remote-updated <iso>. (Only theclaude-codeadapter can see your Claude Design project; no secret goes in the prompt — DesignSync uses the claude.ai login.) IfremoteUpdatedAtis newer thanlastSyncAt, every report warns that the local mirror is OUTDATED until the next/design-sync. Run the check offline/manually withpython scripts/check_designbook_staleness.py --remote-updated <iso>. - If no sync has ever been recorded, the report warns that
/design-synchas not run.
Anthropic's guidance for keeping the system on-brand:
- Give explicit constraints (fonts, colors, spacing, layout) — see
../README.md, which is the authoritative language spec. Vague input drifts to generic output. - Show real rendered UI, not just a token sheet — the
examples/pages double as brand exemplars here. - Test one component before a full page. If output is off, make the language more explicit and retest — cheaper in tokens than fixing a whole screen.
