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 | $0.00107 | $0.00606 |
| Opus 5 | $0.00053 | $0.00303 |
| Sonnet 5 | $0.00021 | $0.00121 |
| Haiku 4.5 | $0.00011 | $0.00061 |
Grade A, and why
library-variables-figma 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 11d 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.
This is a copy
94% identical to figma-library-variables — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
library-variables-figma — discover & import team-library variables
Browse the variables published by libraries the current file subscribes to, then import the ones you need. Imported variables get a local id that behaves like any local variable (bind it, read it, reference it).
Skill boundaries
use_figmarules — load the officialfigma-useskill first; it is the full Figma Plugin API reference. Essentials these scripts rely on: plain JS with top-levelawait+return(no IIFE, nofigma.closePlugin();console.logis not returned), inputs inlined asconstat the top of each script, colors in 0–1 range, load fonts before any text op,await figma.getNodeByIdAsync(...), and atomic errors (a failed script applies nothing — read the error, fix, retry).- Local (non-library) variables →
export-tokens-figma,manage-variables-figma.
Workflow
- Discover. Run
scripts/list-library-variables.jsviause_figma(skillNames: "library-variables-figma"). Optionally set theLIBRARY_NAME/COLLECTION_NAME/TYPEfilters. It returns each subscribed collection and thekeyof every variable in it. - Import. Put the variable
key(s) intoscripts/import-library-variable.jsand run it. It returns the newlocalIdfor each. Re-importing is idempotent (same local id). - Use. Bind the imported variable to node properties or reference it from local semantic tokens
(see
figma-use/manage-variables-figmafor binding).
Notes
- Only subscribed libraries appear. If a collection is missing, enable the library in the file's library settings first (a manual Figma step).
getVariablesInLibraryCollectionAsynctakes the collection key, not its id.- Library variables are read-only references to the source — edit values in the library file, not here.
What ships with it
2 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.

library-variables-figma is a skill published in the GitHub repository southleft/skills-for-figma (14 stars, last pushed 3mo ago), licensed MIT. It adds 107 tokens to every session and 606 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to figma-library-variables, differing in 12 lines, and is treated as a copy.

system-pitch
Write a design system investment pitch with a business case and ROI framing. Trigger when someone says: pitch the design system, make the case for the system, sell this to leadership, justify the investment, business case for design systems, why should we invest in a design system, or anything about building an…
token-audit
Audit a design system's token definitions for naming violations, missing semantic tiers, and structural debt. This audits how tokens are defined and organised, NOT how they are consumed in code. Trigger when someone says: audit my tokens, token naming review, are my tokens consistent, token health check, review my…
ai-component-description
Generate AI-optimised text descriptions for components, formatted for Figma's MCP server and LLM consumption. This produces prose descriptions in a six-section format (purpose, props, anti-patterns, composition, accessibility, examples), NOT JSON schemas or structured data files. Trigger when someone says: write…
context-engine-builder
Generate a context engine — seven structured blueprint files (UX, UI, content, accessibility, ethical, technical, business intelligence) that encode everything an AI agent needs to work with a design system. This produces YAML infrastructure in .ai/context-engine/, NOT a health score or quality assessment. Trigger…
stakeholder-brief
Write a one-page stakeholder brief translating design system health or status into business language. Trigger when someone says: stakeholder update, exec brief, leadership summary, status report for leadership, system status for non-designers, write a brief for the business, or anything about communicating design…
token-compliance
Check a codebase or implementation for token compliance — finding hardcoded values, wrong-tier token references, and inconsistent token application in consuming code. This checks how tokens are used in code, NOT how the tokens themselves are defined or structured. Trigger when someone says: are we using tokens…
