c2d2c:c2d — code to design, every state

Pre-flight: verify the token bridge

Before drawing anything, check that the target file actually has the project's synced tokens — rule 2 below binds against them, and binding into a file where they're missing or stale silently produces raw values or wrong colors.

1. Probe the file (get_variable_defs or a small use_figma query) for the VAR_COLLECTIONS collections; spot-check a few variables' values and $codeSyntax.WEB entries against VAR_SNAPSHOT.
2. Missing → sync them in first: the companion plugin's Pull if the project adopted it, otherwise create the collections via use_figma following the snapshot's layout (see the Tokens section).
3. Present but diverged from the snapshot → refresh them the same way before binding, and mention the drift to the user (it usually means someone skipped the snapshot discipline).

Only then start the export; from here on, binding is automatic — every value the code expresses as a token lands bound to its variable, per rule 2.

Project parameters

Resolve parameters from C2D2C.md at the repo root (fallback: .claude/c2d2c.md); if absent, offer to bootstrap one from the template at ../../templates/C2D2C.template.md (plugin root; standalone installs without that file fetch https://raw.githubusercontent.com/BIAsia/c2d2c/main/templates/C2D2C.template.md). This skill uses EXPORT_FILE (if the user gives a link, the link wins), VAR_COLLECTIONS, VAR_SNAPSHOT, ICON_SOURCE, DS_ROUTE, and for token work TOKEN_HOME, TOKEN_EXPORT.

Three hard rules

1. Enumerate every state first (code census before drawing)

Before drawing anything, enumerate from source every piece of information, content, field, and state the element can show, and put each one on the canvas:

• Every variant axis: tone/size/kind/interactive etc., read from tv()/cx branches and type unions, never guessed from screenshots.
• Every data shape: value/empty/fallback (e.g. favicon fails → initial letter → globe icon), truncation/long text, loading, error.
• Every interaction state: rest/hover/focus/selected/disabled, plus hover popovers (tooltips/hover cards).
• The DS_ROUTE regression pages are a ready-made state checklist; read them first, then patch gaps from render source.
• Put a small gray annotation next to each state (state name + key class/token) for the designers.

2. Bind everything to tokens; no raw styles left behind

• Bind every color, radius, and text style to the already-synced variables and styles in VAR_COLLECTIONS; the inventory of record is VAR_SNAPSHOT.
• CSS var name → Figma variable name resolves through $codeSyntax.WEB (e.g. var(--primary) → Product primary/default).
• Spread paints with alpha become paint opacity or layer opacity bound to the same variable; never fork a new raw color.
• Values Figma cannot express (color-mix/oklch): bind the closest existing variable; if none exists, use the computed literal and record the derivation in the layer name/annotation. Never leave a silent raw color.
• If Figma already has the component/style (from earlier exports, Core/radius/* etc.), bind or instance it; don't redraw.
• Brand assets (third-party logos, favicon bitmaps) are exempt; placeholders are fine.

3. Ask before componentizing

Ask once before exporting: create Figma components (component/variant set) or flat frames? Follow the answer; don't decide unilaterally.

Known gotchas (use_figma, earned over 4+ export jobs)

• Read the /figma-use skill before calling use_figma.
• The code must explicitly return a result or you get nothing back.
• resize flips auto-layout to FIXED along the primary axis and collapses it: resize first, then set sizing back to AUTO (do one recursive fix-up pass at the end).
• Wrap grids need a fixed-width container.
• get_metadata times out on large frames; prefer get_design_context or query in small chunks.
• Switching pages requires await figma.setCurrentPageAsync(page).
• Inter's weight name is "Semi Bold" (with the space).
• Local fonts are invisible to the MCP session: leave a FONT TODO annotation on title layers.
• Split long jobs into multiple small idempotent calls (find-or-create, then mutate) so failures can re-run.
• Never rely on figma.currentPage: the user switching pages mid-run sends later calls to the wrong page. Re-resolve with getNodeByIdAsync(targetPageId) + setCurrentPageAsync on every call, and check for strays at the end.
• setBoundVariableForPaint discards any preset paint opacity, and variables that carry their own alpha get that alpha converted into paint opacity on bind. Correct order: bind first, then set opacity on the returned paint; for alpha-carrying variables the final opacity = variable alpha × CSS multiplier (e.g. /80 → 0.05×0.8=0.04), don't overwrite with 0.8.
• Instance root fills snapshot the master's values at creation time: changing master fills later may not flow into existing instances. Fix: copy master.fills back onto the instance, or delete and recreate it.

Tokens: the same pipeline, different payload

Design tokens are exported state too; the difference is they carry a generated snapshot and a CI gate that keeps the two sides honest.

• Code is the source of truth. When tokens change in TOKEN_HOME (mind every registration point: CSS variable + theme alias + class ladder), run TOKEN_EXPORT to regenerate VAR_SNAPSHOT, and commit the CSS change and the snapshot together. A red check:figma-variables gate means exactly "one side moved without the other" — that is the gate doing its job, not an error to silence. Never hand-edit the snapshot; it is generated output.
• Getting variables into Figma: if the project adopted the companion Token Sync plugin (../../figma-plugin/, source: https://github.com/BIAsia/c2d2c/tree/main/figma-plugin), designers Pull and everything — including bound foundation posters — updates in place. Without the plugin, create/update the variable collections yourself via use_figma, following the same collection/mode/$codeSyntax.WEB layout that VAR_SNAPSHOT records.
• Renames start from the code side: a Figma-side rename arrives as delete + add and orphans every binding.
• Designer-side edits: with the plugin adopted, designer pushes arrive as figma-sync/* MRs, red by design, with safe literal values already written back into the CSS and everything ambiguous itemized for a human. The engineer-side review flow lives in ../../ADAPTING.md (Token sync section; standalone: https://github.com/BIAsia/c2d2c/blob/main/ADAPTING.md).

After exporting

• Self-check with get_screenshot: alignment, lost variable bindings (scan for raw colors), clipped text.
• Reply with the Figma node link.
