What it does
Piece Builder is an agent skill from activepieces/activepieces. Build and edit Activepieces pieces (integrations) — creating new pieces, adding actions or triggers, or fixing bugs in existing ones. Use when the user asks to work on an Activepieces piece, connector, or integration.
Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files (for example `action-patterns.md`, `ai-metadata.md` and `auth-patterns.md`).
It sits in Productivity & Automation, covering MCP servers and Workflow automation. It works with 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.
When your agent uses it
- The user asks to work on an Activepieces piece
- Tasks that involve MCP servers
- Tasks that involve Workflow automation
Example prompts
- “/piece-builder”
Requirements
- Node.js
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- RESEARCH
- PLAN
- SCAFFOLD
- IMPLEMENT
- WIRE & VERIFY
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
Shell commands in SKILL.md call:
npxbunnpm
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:
cdn.activepieces.com
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
Piece Builder loads about 3.1k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 1,326 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:100
V_PIECES=<name>` to `packages/server/api/.env`, start with `npm start`, open `localhost:4200`.
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 1,326 words (~3,135 tokens).
“Golden rule for existing-piece modes: the piece you're editing is the source of truth, not these templates. If the piece already has a helper, a particular auth access pattern, or a way of shaping output, follow that. Reach into the…”
