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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.00508 |
| Opus 5.5 | $0.00029 | $0.00203 |
| Sonnet 5.5 | $0.00015 | $0.00102 |
| Haiku 4.5 | $0.00007 | $0.00051 |
Grade A, and why
figma-design-system-sync 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 1mo 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Figma Design System Sync
Use this skill when Figma work touches reusable system contracts: variables, styles, components, variants, effects, assets, Code Connect, and local code tokens.
Modes
audit: compare Figma system artifacts to local code conventions.sync-plan: plan variable/style/component updates.token-map: map Figma variables to local tokens.component-map: map components and variants to code components.code-connect: create or review Code Connect files through the installed Figma skill.governance: propose naming, versioning, and rollout rules.
Workflow
- Read Figma context with
figma-context-readerunless a current context brief exists. - Inspect the local code tokens/components before recommending sync actions.
- If Code Connect is requested, invoke
figma:figma-code-connectwhen present. - Build a diff: Figma source, code target, status, risk, and proposed change.
- For mutations, route to
figma-canvas-editororfigma-apply-effectswith explicit scope. - Validate JSON/token outputs locally before treating them as evidence.
Guardrails
- Do not rename or delete variables/components/styles without a migration map.
- Do not treat generated code or generated variables as source of truth until reviewed.
- Record which direction is authoritative for each artifact: Figma to code, code to Figma, or reconcile manually.
- Keep variable binding promises compatible with current Figma Plugin API support.
Safety And Privacy
- Treat unpublished tokens, library names, component inventories, and source component code as sensitive.
- Do not push variable/component renames without an explicit migration map and rollback path.
- Do not upload private token exports or component snapshots to external services without approval.

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

figma-design-system-sync is a skill published in the GitHub repository sergekostenchuk/ui-ux-agent-skill-system (32 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 73 tokens to every session and 508 once invoked, about $0.0003 per session on Opus 5.5. 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.
