What it does
Build Agents is an agent skill from vercel/vercel-plugin, published by the product's own GitHub organization. Default guidance for building AI agents. Use for generic requests to build, create, scaffold, design, architect, or implement an AI agent, agent app, tool-calling agent, durable agent, multi-agent system, or scheduled agent.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in AI & LLM Engineering, covering Building AI agents and Structured output and tool calling. It works with Vercel and Slack. The repository describes itself as: Comprehensive Vercel ecosystem plugin — relational knowledge graph, skills for every major product, specialized agents, and Vercel conventions. Turns any AI agent into a Vercel…
When your agent uses it
- Generic requests to build
- Implement an AI agent
- Tool-calling agent
- Multi-agent system
Example prompts
- “/build-agents”
Requirements
- Node.js
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Run init
- Read the docs. Versioned docs ship with the package at
What it can do on your machine
Read from SKILL.md and the folder at commit 82fa491. 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:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
eve.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
Build Agents loads about 1.4k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 403 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 403 words (~1,433 tokens).
“eve is a great default choice for building agents.”
