token-sheet-builder

A Figma page builder that documents a design system’s foundations: colors, typography, spacing, corner shapes, shadows, and other reusable design values.

In plain words
What is it for?
Use it to create or refresh a Foundations page in Figma and show how the design system’s visual rules are organized.
Why use it?
It turns scattered design variables and styles into a visual reference that designers and stakeholders can inspect. Some values update live, while labels and the token list are snapshots.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-sheet-builder 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.

Token sheet builder

Creates a polished visual reference of the design system's tokens and styles on a dedicated Figma page called Foundations. This is the artifact designers and stakeholders actually look at — so it must be beautiful and on-brand, not a utilitarian dump of swatches.

Live vs regenerated — set expectations clearly

Bind to variables wherever Figma allows so the sheet live-updates for those properties: a color swatch bound to gray/50 (in _Color/Primitive) re-colors automatically when that primitive changes; spacing/radius examples bound to the variables resize automatically. But labels, hex/value text, token names, descriptions, and the set of tokens shown (adding/removing tokens) are snapshots — they don't auto-update. So tell the user plainly: "The swatches update live when you change a value, but if you rename tokens, change descriptions, or add/remove tokens, re-run this skill to refresh the page." The sheet is regenerable; re-running refreshes the snapshot parts.

(Tie-in: when the sync skill runs after token changes, refreshing Foundations is a sensible companion step — the sheet and the synced code both reflect Figma.)

Prerequisites

Needs tokens in Figma (tokens.semanticBuilt true) and a live Figma connection. If tokens don't exist, offer to run token-builder. If Figma isn't connected, offer figma-environment-setup. Use the mechanism in figma.mechanism.

Before scripting any figma_execute, read .throughline/references/figma-scripting.md. This sheet builds large swatch/type grids — exactly the layouts that hit the two worst traps: the resize() axis-lock (collapses a color grid or type-meta column to ~10px) and the single-call layoutWrap = "WRAP" timeout on big grids (build manual rows or split across calls instead). Also run the single-bridge-instance preflight before writing.

Execution model — sequential architect → figma-executor with model routing. If your host supports subagent dispatch, plan the sheet layout once with one architect dispatch (deep tier) — a lighter plan than token-builder's, since the tokens already exist; it emits a stable-identifier layout spec (which collections/sections, how much per-token detail) — then build the page with figma-executor dispatches (balanced tier), strictly sequentially: preflight figma_get_status, concurrency-1, WIP: frame + build-verify-then-replace with a programmatic read-back (spot-check that the swatches resolved to their bound variables via figma_get_variables, not just a screenshot), gated by a reviewer visual pass. Route per .throughline/references/agent-routing.md; never parallelize Figma work. If your host has no subagent dispatch, build and verify the page inline, sequentially, as the steps below describe.

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-sheet-builder is a cursor rule published in the GitHub repository jrpease/throughline (76 stars, last pushed 4d ago), licensed MIT. It adds 96 tokens to every session and 2,471 once invoked, about $0.0005 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.
