What it does

Webui Connection Info is an agent skill from lablup/backend.ai-webui. Find WebUI dev server address and Backend.AI API endpoint/credentials for testing. Trigger on: "which server", "connection info", "login credentials", "dev server URL", "API endpoint", "where to connect", "how to login", "test server", or when needing to interact with the running WebUI (screenshots, live checks, E2E). This skill only says where to connect: for the data behind the UI — field meanings, GraphQL queries, live rows — use the bai-agent skill.

Its SKILL.md is about 820 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 REST APIs, End-to-end testing and GraphQL. It works with GraphQL. The repository describes itself as: Backend.AI Web UI for web / desktop app (Windows/Linux/macOS). Backend.AI Web UI provides a convenient environment for users, while allowing various commands to be executed… The licence is LGPL-3.0.

When your agent uses it

  • Connection info
  • Login credentials
  • Where to connect
  • Needing to interact with the running WebUI (screenshots

Example prompts

  • “which server”
  • “connection info”
  • “login credentials”
  • “/webui-connection-info”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. The boot records — ~/.local/state/fw/dev-servers/*.json, one per Portless app,
  2. portless list — live routes on this box.
  3. The pnpm run dev terminal output — Portless prints the full URL on startup.

What it can do on your machine

Read from SKILL.md and the folder at commit 10554dc. 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

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • E2E_ADMIN_PASSWORD
    • E2E_USER_PASSWORD

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Webui Connection Info loads about 817 tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 366 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~120
When it runs · the whole SKILL.md, loaded when a task matches
~817

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:39
    Read `e2e/envs/.env.playwright` to get the current server endpoint and login credentials.
  • NoteMentions a .env fileSKILL.md:60
    - The `.env.playwright` file may have multiple endpoints commented out (e.g., LTS vs main). Use the **uncommented** `E2E

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.

Trigger on: "which server", "connection info", "login credentials", "dev server URL", "API endpoint", "where to connect", "how to login", "test server", or when needing to interact with the running WebUI (screenshots, live checks, E2E).

WebUI Connection Info

Dev Server Address

The WebUI dev server runs under Portless on a *.localhost:1355 URL.

scripts/dev.mjs names the app from the branch's issue key, its PR number and a descriptive word — e.g. https://fr-3665-pr9049-statusline.localhost:1355, or https://gh-10144-pr10150-drawer.localhost:1355 on a gh-N (GitHub issue) branch; off a legacy FR or gh-N branch Portless derives the name. Don't construct the URL — read it from a source below.

Never assume port 1355: when another Portless daemon is already bound there (another Claude session / worktree), the server lands on 1356, 1357, … — always confirm the real port from one of the sources below.

To find the actual URL for a running instance, check these sources in order:

  1. The boot records — ~/.local/state/fw/dev-servers/*.json, one per Portless app, written by the dev-server skill. Each carries url (the gateway URL a teammate can open), localUrl, branch, pid, startedAt/stoppedAt and the PRs it serves. A record with stoppedAt set is a server that is gone. This is the only source that says which branch and PRs a server is for, so start here.
  2. portless list — live routes on this box.
  3. The pnpm run dev terminal output — Portless prints the full URL on startup.

If no dev server is running, tell the user to start it with pnpm run dev (Portless is a devDependency and dev.mjs starts its daemon; no global install).

API Endpoint & Credentials

Read e2e/envs/.env.playwright to get the current server endpoint and login credentials.

Key variables:

  • E2E_WEBSERVER_ENDPOINT — Backend.AI API server URL
  • E2E_ADMIN_EMAIL / E2E_ADMIN_PASSWORD — admin account
  • E2E_USER_EMAIL / E2E_USER_PASSWORD — regular user account
  • Additional: E2E_USER2_*, E2E_MONITOR_*, E2E_DOMAIN_ADMIN_*

Always read the file fresh — credentials and endpoints change. Do not hardcode or cache them.

Login Flow

The WebUI login page requires:

  1. Email/Username
  2. Password
  3. Endpoint (may be hidden under "Advanced" toggle)

The app uses config.toml with connectionMode = "SESSION". If apiEndpoint is empty, the user must enter the endpoint manually on the login page.

Gotchas

  • The .env.playwright file may have multiple endpoints commented out (e.g., LTS vs main). Use the uncommented E2E_WEBSERVER_ENDPOINT.
  • Passwords may contain special characters — handle quoting carefully.
  • The webpack-dev-server overlay can intercept clicks. Remove it via: document.getElementById('webpack-dev-server-client-overlay')?.remove()
  • If the "Endpoint" input field is not visible on the login page, click "Advanced" to expand it.
