What it does
Build An App is an agent skill from BuilderIO/agent-native. Fast end-to-end workflow for turning this starter into a working domain app from a short or vague request. Use when asked to build, make, create, or prototype an app, tool, tracker, dashboard, booking, inventory, or CRM system with Agent-Native. Read before the first edit.
Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/data-and-access.md`, `references/edit-points-chat.md` and `references/edit-points-default.md`).
It sits in Sales & Support. The repository describes itself as: A framework for building agentic apps.
When your agent uses it
- Prototype an app
- CRM system with Agent-Native
Example prompts
- “/build-an-app”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Orient
- Decide
- Build: write everything, then verify once
- Verify, once, in this order
- Report
What it can do on your machine
Read from SKILL.md and the folder at commit e16da0c. 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:
pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
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 An App loads about 2.5k tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 1,360 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,360 words (~2,463 tokens).
“Done means one useful domain workflow with a designed route, shared UI/agent actions, correct access, agent context, and a smoke run that proves its key rule. Finish a narrow slice before expanding it.”
