whynot-design/designbook

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.

Refresh runbook — propagating a designbook change to Lit (WHYNOT-WP-0002)

When the cloud designbook moves, run make designbook-refresh — it chains check → pull → record → make ir → make adapt-lit → (drift triage) → make parity-lit and stops when a human decision is needed. See .claude/rules/stack-and-commands.md for the step list and .claude/rules/designbook-propagation.md for the one-way governance.

Step 6 — resolving drift (the human step). When make adapt-lit exits 3, the refresh halts and points you at adapters/lit/drift/<Name>.md. For each actionable issue (informational non-portable/prop-extra are not gated):

drift kind	what it means	how to resolve
attribute-mismatch	the Lit property reflects a different attribute than the IR contract	rename the Lit attribute: to match the IR, or — if the language is what's wrong — change it in Claude Design and re-propagate
prop-missing	the IR contract has a prop the <wn-*> element lacks	add the reactive property + behaviour to the element, or if the element models it differently (e.g. a slot, or state on a child), change the React designbook so the contract matches reality
variant-axis-missing	an IR variant axis has no backing Lit property	add the variant property, or correct the axis in Claude Design
tag-mismatch	the IR contract's tag has no element; a near-named one exists (e.g. wn-pipeline-strip vs the hand-authored wn-pipeline)	decide the canonical name in Claude Design and re-propagate, then realign the element — do not silently rename only the stack

Never resolve drift by editing ir/ or back-editing React from the stack — that desyncs the canonical source (see designbook-propagation.md). After resolving, re-run make designbook-refresh --no-pull to confirm adapt-lit is clean and parity-lit passes (exit 0). New components get a write-once stub in adapters/lit/stubs/<Name>.js — move it into src/elements/, implement the behaviour, register it, and re-run.

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) sets lastSyncAt to now. RecentChanges.md and the make output then show "Last /design-sync: <datetime>".
• To detect that the cloud moved ahead, run make designbook-check — backed by llm-connect. It uses the claude-code adapter to ask the local claude binary for the project's current updatedAt via DesignSync.list_projects, then records it with node scripts/designbook-sync.mjs --remote-updated <iso>. (Only the claude-code adapter can see your Claude Design project; no secret goes in the prompt — DesignSync uses the claude.ai login.) If remoteUpdatedAt is newer than lastSyncAt, every report warns that the local mirror is OUTDATED until the next /design-sync. Run the check offline/manually with python scripts/check_designbook_staleness.py --remote-updated <iso>.
• If no sync has ever been recorded, the report warns that /design-sync has 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.
