What it does
Authentication is an agent skill from BuilderIO/agent-native. How auth works in agent-native apps. Use when wiring login/signup, configuring auth modes, setting up organizations, protecting routes, or debugging session issues.
Its SKILL.md is about 6.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Authentication. It works with Better Auth. The repository describes itself as: A framework for building agentic apps.
When your agent uses it
- Wiring login/signup
- Configuring auth modes
- Setting up organizations
- Protecting routes
Example prompts
- “/authentication”
Requirements
- Node.js
- A credential in ACCESS_TOKEN
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:
pnpmnpx
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:
dispatch.agent-native.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
A2A_SECRETACCESS_TOKENAGENT_NATIVE_IDENTITY_FEDERATION_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Authentication loads about 6.8k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 3,427 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:303
d persist shared browser credentials in `.env`. Agents then use the built-in `get-browser-connection` tool to provision
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 3,427 words (~6,813 tokens).
“Auth is powered by Better Auth with account-first design. Every new user creates an account on first visit. Use getSession(event) to authenticate custom routes; actions are auto-protected. Normal app HTML and React Router page-data responses are one impersonal, public-cacheable shell…”
