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 | $0.00096 | $0.00852 |
| Opus 5 | $0.00048 | $0.00426 |
| Sonnet 5 | $0.00019 | $0.00170 |
| Haiku 4.5 | $0.00010 | $0.00085 |
Grade A, and why
figma-apply-effects 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.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Figma Apply Effects
Use this skill for Figma Effects. It replaces the outdated rule that Figma supports only four effect types. Current Figma Plugin typings include shadow, blur, noise, texture, and glass effect families, but MCP/client support can lag behind typings, so advanced effects are runtime-gated.
Modes
apply: add one or more effects to selected nodes.remove: remove all effects or selected effect families.style: apply an existing Effect Style.bind: bind supported effect fields to variables.audit: inspect current effects and compatibility.recipe: translate visual language like glow, glassmorphism, soft elevation, grit, or texture into effect objects.
Required Workflow
- Confirm target node(s), visual intent, whether to replace or append effects, and privacy scope.
- Invoke
figma:figma-usebefore anyuse_figmacall. - Read the selected node metadata first:
effects,fills, style IDs, variable bindings, and current opacity. - If the user asks for an existing Effect Style, search/select that style first and apply the style if available.
- If raw effects are needed, use references/effect-compatibility.md to choose the effect family.
- For
BACKGROUND_BLUR, check that the node has a visible fill with alpha below1; otherwise the blur will be visually hidden. - For glow, use a
DROP_SHADOWrecipe: bright color,offset: { x: 0, y: 0 }, larger radius, and low-to-medium alpha. - For variables, bind only supported fields. Shadow effects support
color,radius,spread,offsetX, andoffsetY; blur effects supportradius; noise, texture, and glass effects currently do not support variable binding in Figma plugin typings. - Write the returned bound effect object back to the node's
effectsarray. - Read metadata back and report exact effects, bindings, skipped fields, and visual caveats.
Effect Families
Guaranteed core families when the runtime exposes standard Figma effects:
What ships with it
4 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-apply-effects is a skill published in the GitHub repository sergekostenchuk/ui-ux-agent-skill-system (23 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 96 tokens to every session and 852 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.
