token-sync-layer

A one-way pipeline that turns design variables from Figma into code files. Figma is the source of truth, and the generated files can target systems such as Tailwind, MUI, CSS, iOS, or Android.

In plain words
What is it for?
Use it to sync Figma variables, generate platform-specific token files, and install a reusable command for repeating the sync.
Why use it?
It removes manual copying of shared design values such as colours, spacing, and type sizes into code. Re-running the command keeps the code outputs aligned with Figma changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

token-sync-layer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 304 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Token sync layer

Compiles Figma variables into code. The pipeline is one-directional — Figma is the source of truth for token values; code consumes generated artifacts that are never hand-edited:

Figma variables → DTCG JSON → Style Dictionary → adapter output (per platform)

This skill both performs the sync and installs the reusable /sync-figma-tokens command so the user can re-run it anytime tokens change.

Calibrate

Read user.codingLevel (.throughline/references/coding-level.md) and scale explanation accordingly. The pipeline involves several developer concepts (JSON, build tools, PRs) — for new users, explain each plainly the first time; for comfortable users, be terse. Actions are identical across levels.

Prerequisites (offer to run them, don't bail)

Read the manifest. This skill needs two things:

  1. Tokens in Figmatokens.semanticBuilt should be true. If no tokens exist, offer to run token-builder first.
  2. At least a local git repoworkspace.stage must be local-git or github (so the sync can land changes as a reviewable diff/PR). If it's still folder, this is the soft-nudge seam: offer to run repository-builder to add version history first. Explain plainly why ("the sync writes code files, and git lets you review exactly what changed before keeping it"). If the user is at local-git but not github, strongly recommend connecting a remote (GitHub or similar) so the sync can land as a real reviewable PR — the cleanest review model — but don't force it; a reviewed branch diff works at local-git.

A live Figma connection is also required — do a cheap liveness read; if it fails, offer figma-environment-setup.

Step 1 — Choose target platform(s)

Ask which platform(s) the user is building for. Read .throughline/references/sync-adapters.md for the two-tier adapter model.

  • Curated (Tier 1): shadcn, tailwind, mui, vanilla-css, ios-swift. Vetted presets — high confidence.
  • Generated (Tier 2): any other framework (Ant Design, Chakra, HeroUI, Android/Kotlin, Flutter, etc.). The skill generates an adapter and verifies it against a real component before trusting it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

token-sync-layer is a cursor rule published in the GitHub repository jrpease/throughline (76 stars, last pushed 4d ago), licensed MIT. It adds 126 tokens to every session and 4,133 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
