What it does
Activepieces Design System is an agent skill from activepieces/activepieces. Design system for Activepieces (open-source AI automation platform, "open source replacement for Zapier"). Use whenever designing, mocking, or building UI for Activepieces — the web app (flow builder, runs, connections, dashboard), docs, or marketing surfaces. Provides brand purple 8142E3, Inter type ramp with sm (14px) as body default, Tailwind neutrals, Lucide icons, Shadcn/Radix primitive conventions, the signature dotted-canvas builder background, and a recreated web UI kit.
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Frontend & Design, covering Design systems and Workflow automation. It works with shadcn/ui, Tailwind CSS, Zapier and Model Context Protocol. The repository describes itself as: AI Agents & MCPs & AI Workflow Automation • (~400 MCP servers for AI agents) • AI Automation / AI Agent with MCPs • AI Workflows & AI Agents • MCPs for AI Agents.

Workflow steps
12 steps, taken from the first numbered list in SKILL.md.
- Primary is purple hsl(257 74% 57%) / #8142E3 — the shipping value from packages/web/src/styles.css. Not the #9747FF swatch some Figma…
- Body text is 14px (text-sm), not 16. Activepieces feels dense and tool-like. Headings use -0.01em to -0.02em tracking. The agent editor's…
- Sentence case everywhere: headings, buttons, menu items, page titles. Proper nouns only for feature names (Flows, Runs, Pieces, MCP…
- Lucide icons only, 1.5–2px stroke, rounded caps. Default size 16 (size-4). Icon + text → gap-2 (8px). No emoji in the product UI. No…
- Borders are 1px, color neutral-200 (light) / white/14 (dark). Never thicker. (Note: repo ships white/10 in dark — we bump to 14% so…
- No negative margins. Use gap-*, p-*, space-*. Explicitly banned in the repo's AGENTS.md.
- Cards: white fill, 1px border, radius-lg (10px), NO shadow by default. Shadows only on floating surfaces (popovers, menus, dialogs). One…
- Main content is a floating card: the sidebar blends with the outer shell (neutral-50 in light, neutral-950 in dark); the content area sits…
- Builder canvas has the dotted look — background #FBFBFB (light) / #171717 (dark), radial-gradient dots #b2b2b2 1px at 16px 16px. This is…
- Hover states darken only — primary buttons go to /90, secondary /80, ghost bg-gray-300/30. No scale, no translate, no elevation change on…
- Focus-visible is a 3px ring at ring-color/50 — accessibility-first, very visible.
- Disabled: opacity: 0.5; pointer-events: none. No greyed-out variant.
What it can do on your machine
Read from SKILL.md and the folder at commit 8656fb8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are css and html).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
unpkg.com
Also links to:
lucide.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Activepieces Design System loads about 3.6k tokens when it runs. Until then it costs about 129 tokens; SKILL.md has 1,613 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,613 words (~3,579 tokens).
“You are designing for Activepieces — an open-source AI automation platform where users assemble triggers + actions from 280+ "pieces" into automated flows. Every piece doubles as an MCP server.”
