What it does
Auth is an agent skill from EpicenterHQ/epicenter. Epicenter auth packages: @epicenter/auth and the Svelte adapter at @epicenter/auth/svelte, OAuth sessions, identity state, auth-owned fetch/WebSocket, and the reload gate that makes a page lifetime one auth generation. Use when editing Epicenter auth clients, session state, hosted sign-in, or how a route boots from auth.
Its SKILL.md is about 7k 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 OAuth and OpenID Connect, Realtime and WebSockets and Session handoff. It works with Svelte and Better Auth. The repository describes itself as: Open-source, local-first apps.
When your agent uses it
- Editing Epicenter auth clients
- How a route boots from auth
Example prompts
- “/auth”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Keep accessTokenExpiresIn short (10 minutes). The client refreshes
- A route that authenticates only at the WebSocket upgrade MUST bound the
- Close codes and statuses carry meaning the client acts on
What it can do on your machine
Read from SKILL.md and the folder at commit 9cc65c3. 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 typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Auth loads about 7k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 3,041 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 3,041 words (~6,979 tokens).
“When changes depend on Better Auth OAuth provider behavior, bearer token verification, cookie handling, token rotation, plugin shape, JWKS, or generated API shape, ask DeepWiki a narrow question against better-auth/better-auth before relying on memory. Use it to orient, then verify…”

Auth is an agent skill from EpicenterHQ/epicenter. Epicenter auth packages: @epicenter/auth and the Svelte adapter at @epicenter/auth/svelte, OAuth sessions, identity state, auth-owned fetch/WebSocket, and the reload gate that makes a page lifetime one auth generation.
When should I use Auth?
Auth fits situations like: editing Epicenter auth clients; how a route boots from auth.
How do I install Auth in Claude Code?
Run `npx skills add EpicenterHQ/epicenter --skill auth -a claude-code`. Or copy the skill folder (.agents/skills/auth in EpicenterHQ/epicenter) into .claude/skills/auth in your project. Claude Code loads it when a task matches its description.
How do I install Auth in Codex?
Run `npx skills add EpicenterHQ/epicenter --skill auth -a codex`. Or copy the skill folder (.agents/skills/auth in EpicenterHQ/epicenter) into .agents/skills/auth in your project. Codex loads it when a task matches its description.
Can I use Auth in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add EpicenterHQ/epicenter --skill auth -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/auth, .gemini/skills/auth, .github/skills/auth and .opencode/skills/auth in your project.
What does Auth need to run?
SKILL.md names no scripts, command-line tools or credentials: Auth is instructions for the agent only.
Does Auth access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Auth safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Auth use?
Auth has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Auth use?
About 7k tokens (SKILL.md is roughly 28k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Auth?
Skills that share tags, products or a category with Auth: Neon Auth (neondatabase/agent-skills, 100 stars), Test Convt Web (opencoredev/convt, 187 stars), Better Auth Security Best Practices (agutinbaigo28/financial-agent-api, 128 stars) and Tanstack Query (exceptionless/Exceptionless, 2.5k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Auth?
EpicenterHQ (a GitHub organization) maintains it in EpicenterHQ/epicenter, which has 4,819 GitHub stars. The repository holds 65 skills in this directory. The repository was last updated on October 8, 2026.
