Explorbot Setup
Install Explorbot, write a working config, give it the bare minimum knowledge to reach the user's app, and prove the install by getting explorbot navigate <page> to exit 0.
Scope ends at a successful navigate. Running explore, plan, test, freesail, etc. is not part of setup — once navigate works, hand the user off to explorbot-fundamentals.
Do the work — don't narrate it. Run installs, run explorbot init, edit explorbot.config.js, run curl, run explorbot navigate, run explorbot learn yourself. The user is only asked for the things only they know:
- AI provider + API key
- App URL (the value of
web.url)
- The page to verify against
- Login credentials (only if
navigate fails on an auth wall)
Don't pre-collect those four upfront — ask each one at the moment it's actually needed, and only ask for credentials at all if the ladder shows they're needed.
Communication style — friendly and explanatory
This is the user's first contact with Explorbot. Most of them have never seen it before. Don't be terse, don't be transactional, and don't dump options without context.
Before every ask and before every install step, write 2–4 sentences that cover:
- What is about to happen ("I'm going to install Playwright's browsers — about 250MB, takes a couple of minutes.")
- Why it's needed ("Explorbot drives a real browser to click around your app like a user would — Playwright is the engine, the browsers are what it drives.")
- What the user gets from it ("Once this is done, Explorbot can navigate any URL on your app and try things autonomously.")
When asking a question, explain the choice itself — what each option means, what the trade-off is, why you recommend one. Don't make the user guess what a label means.
When showing a long command or a config snippet you're about to apply, say in one sentence what it does first.
After every step, give a short progress note ("Installed. Next: …") so the user knows where they are in a multi-step process. Use light formatting (a single emoji or **Step N/6** markers) only when it actually helps — never decorate for the sake of it.
Keep the tone warm and confident, not apologetic. Errors get a friendly explanation of what likely went wrong and what you'll try next, not a wall of stack trace.
Precondition check
If explorbot.config.{js,mjs,ts} already exists (also check config/, src/config/) and the user is already running Explorbot, stop and route them to explorbot-fundamentals — this skill is for first-time install.
1 — Install
Verify Node ≥ 24 (or Bun) first; if neither is available, stop and tell the user — don't try to install a runtime.
Make sure package.json exists and is ESM. Explorbot's generated config uses import … statements, which need "type": "module". The default npm init -y produces CommonJS — that breaks the config. If there's no package.json in the project, create one as ESM:
npm init -y
npm pkg set type=module
If package.json already exists but "type" is missing or set to "commonjs", ask the user before changing it (could affect their existing code). If they consent, run npm pkg set type=module. If they don't, you'll need to write the explorbot config as .mjs instead and pass --config-path explorbot.config.mjs to every command.
Then install Explorbot and the browsers it drives:
npm i explorbot --save
npx playwright install
Explain to the user before running these, in this spirit (paraphrase, don't paste verbatim):
"Two installs coming up. First, npm i explorbot --save pulls Explorbot into your project — the CLI you'll use to run everything later. Then npx playwright install downloads the Chromium / Firefox / WebKit browser binaries (~250MB, takes a minute or two). Explorbot drives a real browser to interact with your app the way a person would — clicks, forms, navigation — and Playwright is the engine that lets it do that. Without these browsers, Explorbot has nothing to drive."
If the user's app is a landing page, blog, or CMS, stop and warn them before installing — Explorbot is built for CRUD-heavy apps (SaaS, admin panels, ecommerce, ERPs, internal tools) and performs poorly on static / content sites. Explain why (it learns by interacting with forms, tables, CRUD actions — there's nothing for it to do on a marketing page). Continue only if they confirm.
2 — Initialize the config
Run:
npx explorbot init
This creates explorbot.config.js and .env. For flag options (--config-path, --force, --path), check npx explorbot init --help.
3 — Configure web.url and an AI provider
Read the generated explorbot.config.js — explorbot init writes a working template with placeholders. Work from that file's current shape; don't paste a config from memory.
Ask the user two things, then edit the file:
- App URL —
web.url (host only, no path).
- AI provider + API key — which one (OpenRouter / OpenAI / Anthropic / Groq / Cerebras / Azure / Google) and the key value.
How to ask for the URL — explain, then ask (no guessing)
The app under test is the user's app — could be a local dev server (http://localhost:<port>) or one of their hosted environments (staging / dev / production). You cannot guess it. Do not pre-fill URL options with "common defaults" and never with unrelated apps (app.testomat.io, example.com, anything from the skill's metadata).
Before asking, explain why you need it in this spirit:
"Explorbot needs to know which web app to test. This is set as web.url in explorbot.config.js and becomes the base for every navigation — paths like /login or /dashboard will be resolved against it. It can be a local dev server (something running on localhost) or a hosted environment you own — staging or dev are usually safer than production, since Explorbot will click, fill, and submit forms autonomously and could create or change data."
Then:
- Look for evidence in the project first — read
package.json scripts for dev / start / serve lines, check .env / .env.example for BASE_URL / APP_URL / NEXT_PUBLIC_*_URL / VITE_*_URL, look at framework config (next.config.*, vite.config.*, vue.config.*) for a port setting. If you find a concrete URL or port, surface it as a suggestion with its source ("Found PORT=4000 in .env — use http://localhost:4000?"). Never invent a URL without an actual source in the project.
- Optionally probe ports the project implies — if
package.json runs next dev, Next's default is 3000; check whether http://localhost:3000 actually responds via curl. Only suggest a port that something is currently listening on, and say so ("Something is listening on localhost:3000 — is that your app?").
- If no evidence — ask in plain text: "What's the URL of the app Explorbot should test? Local (e.g.
http://localhost:<port>) or a hosted environment of yours (staging / dev / production — please avoid production if it'll create real data)?" No multiple-choice list, no guesses.
Confirm what they answer back to them before writing it into the config.
How to ask for the AI provider — explain first
Most users have never connected an LLM to a test tool before. Before asking, explain what's happening and why, in this spirit:
"Explorbot is driven by an LLM — that's what looks at each page, decides what to click, fills forms intelligently, and judges whether a test passed. So Explorbot needs API access to a model, which means a token-based API key from a provider you have an account with. Costs are per-token (typically cents per exploration run), nothing fixed or monthly. The key stays local — written to .env in this project — and .env will be gitignored.
Three providers I'd suggest, in order:
- OpenRouter — easiest to start with. One account, one key, access to almost every model (OpenAI, Anthropic, Meta, Mistral, etc.) so you can swap models without re-onboarding. Good if you don't have a strong preference.
- OpenAI — if you already have an OpenAI key, this is one less account.
- Anthropic — if you already use Claude, same reason.
Anything else that Vercel's AI SDK supports also works (Groq, Cerebras, Azure OpenAI, Google Gemini, etc.) — tell me which one and I'll wire it."
Then ask which one (and the API key value), and act on it:
- The template
explorbot init generated already imports a provider; if the user picks a different one, swap the import line + the three model: / visionModel: / agenticModel: lines accordingly.
- The provider package follows the Vercel AI SDK convention:
@openrouter/ai-sdk-provider, @ai-sdk/openai, @ai-sdk/anthropic, @ai-sdk/groq, @ai-sdk/google, @ai-sdk/azure, etc. npm i the matching one if it isn't already a dep — tell the user what you're installing and why.
- Reference the key in the config as
process.env.<KEY_NAME> (e.g. process.env.OPENROUTER_API_KEY) and confirm .env is in .gitignore. If it isn't, explain why you want to add it ("so your key doesn't end up in git history") and add it.
How to get the key into .env — offer three options, recommend the editor
The key itself never has to pass through the chat. Present these three options and recommend option 1:
-
Edit .env yourself, then continue (recommended). This is the most secure path — the key never goes through chat, never lands in transcripts or logs. Say to the user, in this spirit:
"I'd recommend the safest way: open .env in your editor, add the line OPENROUTER_API_KEY=… (paste the value there), save, then just tell me 'continue' or 'ready' and I'll pick up the verification step. The key never has to pass through this chat that way."
When they confirm they've saved it, verify it's set before continuing:
grep -q "^<KEY_NAME>=." .env && echo "key present" || echo "key missing"
If "key missing", tell them and wait — don't proceed to step 5.
-
Paste the key here and I'll write it. Less secure (the key passes through chat), but convenient. Only use this if the user explicitly prefers it. When they paste, write it to .env immediately and do not echo the value back in your reply.
-
Skip for now — I'll set it up later. Legitimate, but be clear: setup will stop at step 4, no verification will run. They'll finish by editing .env themselves and then running npx explorbot navigate <path> --session manually. Recommend they come back through explorbot-fundamentals once the key is in place.
Do not list these in a 1/2/3 multiple-choice prompt where #1 looks just as casual as the others — call option 1 out as the recommended one in your explanation, and frame option 2 as the less-secure alternative.
(Once Explorbot is installed, the canonical reference for everything in this section is node_modules/explorbot/docs/configuration.md and node_modules/explorbot/docs/providers.md. The fundamentals skill uses these — setup shouldn't need them unless the generated template is unclear.)
4 — Pick the verification page
Before asking, explain why:
"Setup isn't done until I've proven Explorbot can actually open a page on your app — that catches network issues, wrong URL, auth walls, or a misconfigured browser before we waste a real exploration run. Pick any page on your app: the home page (/), a login page (/login), or a specific area you'll want to test later (e.g. /admin/users). I'll try a cheap reachability check first, then ask Explorbot to navigate there."
Then ask: "Which page should I use for the verification? You can paste a full URL or just a path like /login."
If they mention login is required up front, ask for credentials now (see step 5C for how — same flow). Otherwise wait; the ladder will surface it cleanly if it's needed.
5 — Verify with the accessibility ladder
Walk these rungs in order. Stop at the first failure, fix it, then resume. Do not skip ahead.
digraph accessibility_ladder {
rankdir=TB;
"A. curl page" [shape=box];
"A.5 curl -IL follow redirects" [shape=box];
"B. explorbot navigate --session" [shape=box];
"C. teach auth (knowledge → creds)" [shape=box];
"Setup done → handoff" [shape=doublecircle];
"host reachable?" [shape=diamond];
"page gated (3xx/401/403)?" [shape=diamond];
"final URL looks like login?" [shape=diamond];
"navigate exit 0?" [shape=diamond];
"auth wall after the fact?" [shape=diamond];
"A. curl page" -> "host reachable?";
"host reachable?" -> "fix env (VPN, DNS, web.url), retry A" [label="no"];
"host reachable?" -> "page gated (3xx/401/403)?" [label="yes"];
"page gated (3xx/401/403)?" -> "B. explorbot navigate --session" [label="no (200)"];
"page gated (3xx/401/403)?" -> "A.5 curl -IL follow redirects" [label="yes"];
"A.5 curl -IL follow redirects" -> "final URL looks like login?";
"final URL looks like login?" -> "C. teach auth (knowledge → creds)" [label="yes"];
"final URL looks like login?" -> "B. explorbot navigate --session" [label="no (plain redirect)"];
"C. teach auth (knowledge → creds)" -> "B. explorbot navigate --session" [label="knows → learn → ask → verify .env"];
"B. explorbot navigate --session" -> "navigate exit 0?";
"navigate exit 0?" -> "Setup done → handoff" [label="yes"];
"navigate exit 0?" -> "auth wall after the fact?" [label="no"];
"auth wall after the fact?" -> "C. teach auth (knowledge → creds)" [label="yes"];
"auth wall after the fact?" -> "read output/explorbot.log, fix knowledge, retry B" [label="no"];
}
A — curl the host
Run a cheap network check before involving Explorbot. Build the full URL from the web.url you just wrote into the config plus the verification path.
curl -sS -o /dev/null -w "HTTP %{http_code} in %{time_total}s\n" <full-url-to-target-page>
Interpret the result yourself:
000 → DNS / VPN / wrong host / web.url wrong. Tell the user what's likely wrong (VPN, DNS, typo in URL), fix what you can, re-run A.200 → host is up and serving the page; continue to B.3xx / 401 / 403 → host is up but the page is gated. Run A.5 first.5xx → the app itself is broken. Stop and report to the user.
A.5 — Auth probe (only when A returned 3xx / 401 / 403)
Don't fire explorbot navigate blind into an auth wall — that wastes an AI run when you can already tell credentials will be needed. Follow the redirects with curl and see where the host actually sends an unauthenticated request:
curl -sIL -o /dev/null -w "final=%{url_effective}\nhttp=%{http_code}\n" <full-url-to-target-page>
Look at the final URL and decide:
- The final URL path contains
login, sign_in, signin, auth, session/new, account/login, oauth, sso, idp, or returns 401 / 403 after following redirects → the app needs credentials. Jump to step C now (before B), gather credentials, store them, and only then run B.
- The final URL is just a different non-auth path (e.g.
/ → /dashboard because there's a working session, or /old-url → /new-url) → no auth needed, continue straight to B.
- Ambiguous (e.g. lands on
/ with no login-like keywords)? Tell the user what you saw ("/ redirected to /welcome — is that page open to anonymous users, or does it need a login?") and let them decide.
Tell the user what you found before asking, in this spirit:
"Heads up — curl on / returned 302 and follows through to https://beta.testomat.io/users/sign_in. That's a login page, so Explorbot will hit the same wall when it tries to navigate. Let me grab credentials from you now so the verification run actually gets past it."
Then go to C, then B.
B — explorbot navigate
Run the AI Navigator against the target page. It handles redirects, login walls, and recoverable errors.
npx explorbot navigate <path> --session
--session captures cookies/localStorage into output/session.json so subsequent setup attempts reuse the auth. For other flags, check npx explorbot navigate --help on the spot.
Interpret the exit code:
- Exit
0 → setup is done. Go to step 6.
- Exit
1 → read output/explorbot.log and figure out why. If it's a login redirect / 401 / 403, go to C. Otherwise the cause is not credentials (wrong URL, missing wait, app down): fix the knowledge or the config yourself if you can, and re-run B. If you can't tell, surface the log excerpt to the user and ask.
C — Teach Explorbot about auth (knowledge first, then credentials)
Enter step C either because step A.5 detected a login redirect or because step B's navigate landed on auth. Do not invent credentials. Do not loop without asking.
The order matters. Knowledge (the markdown file that tells Explorbot how to authenticate) is written first, using placeholder env-var references. Real credentials go into .env afterwards. If you ask for credentials first and only write knowledge later, you'll race the user — they'll fill .env, say "continue", and you'll run navigate against a config that still has no knowledge file. That's the exact bug to avoid.
C.1 — Check what knowledge already exists
Before writing anything, see what knowledge/ already has for this URL — there might be auth knowledge from a prior attempt or from the user's own work, and you should not duplicate it.
npx explorbot knows <auth-page-path>
npx explorbot knows
If an entry already covers sign-in for this URL, read it (open the file under knowledge/), note which env vars it references, and skip C.2 — jump to C.3 and ask the user to populate those existing vars in .env.
If nothing relevant is there, continue to C.2.
C.2 — Write knowledge with env-var placeholders (no real secrets yet)
Pick env var names you'll ask the user to populate next — APP_USER / APP_PASSWORD are sensible defaults; if existing knowledge already references env vars, reuse those names. Then run explorbot learn with a simple body that names the credentials and references the env vars. Do not invent field selectors, CSS, or DOM hints — the Navigator figures those out on its own; over-specifying makes the knowledge brittle.
npx explorbot learn "<auth-page-path>" "Sign in with \${env.APP_USER} / \${env.APP_PASSWORD}."
Confirm with npx explorbot knows <auth-page-path> (or by reading the file under knowledge/) that the placeholders survived literally — no real values, no escaped backslashes that broke the substitution.
Tell the user in plain language what you just did, in this spirit:
"I wrote knowledge/<file>.md so Explorbot knows it should sign in on <auth-page-path> using the env vars APP_USER / APP_PASSWORD. No real credentials are in that file — it just references those two variables. Now I need the actual values."
C.3 — Ask for the actual credentials, recommend the editor
Explain first what's happening and the safety implications:
"The knowledge file is in place but it references env vars that don't have values yet. Please add the two values to .env (which is gitignored, so they stay local). I'd recommend the safest path — open .env in your editor, add the two lines, save, and tell me 'continue'. The credentials never have to pass through this chat.
A safety note: please use a test account, not a real admin / personal one — Explorbot will click and submit autonomously, so anything that account can do, it might do. If your app has a staging or dev environment, point at that."
Offer the same three options you use for the API key in step 3 (edit .env yourself recommended; paste here less secure; skip setup stops here). Tell them exactly which lines to add:
APP_USER=…
APP_PASSWORD=…
If you also need to know the login URL, the role / workspace / tenant, or anything else, ask for those too — but only if the Navigator can't reasonably infer them from the page.
C.4 — Verify the env vars are set, then retry navigate
When the user says "continue", verify before invoking navigate:
grep -E "^(APP_USER|APP_PASSWORD)=." .env >/dev/null && echo "creds set" || echo "creds missing"
If "creds missing", tell the user which line is empty and wait — don't proceed.
If "creds set", retry step B (npx explorbot navigate <path> --session). If navigate now exits 0, setup is done. If it still fails:
- Read
output/explorbot.log for the actual cause.
- If it still looks like an auth issue, the knowledge body may need a small hint (e.g. the user lands on
/login but /users/sign_in is the actual form, or the app has SSO / a second factor). Re-run explorbot learn with one short added sentence, not a rewrite. Then retry navigate.
- If it's not auth (wrong URL, missing wait, server error), share the log excerpt with the user and decide together — don't loop blindly.
6 — Handoff
When explorbot navigate <path> --session exits 0, setup is complete. Give the user a warm wrap-up, in this spirit:
"🎉 Setup is done — Explorbot just opened <path> on your app successfully. Here's where you stand:
explorbot.config.js is configured with your URL and AI provider.- Your API key and any credentials are in
.env (gitignored).
output/session.json holds a working browser session, so future runs won't re-login.
From here, you'd typically:
- Run
npx explorbot research <path> to see what Explorbot understands about a page (cheap, no testing yet).
- Run
npx explorbot explore <path> --max-tests 10 for a real exploration cycle (research → plan → test).
- Or write a plan by hand and run it with
npx explorbot test <plan.md>.
The explorbot-fundamentals skill walks through all of that and is what you'll want for everything beyond setup. Want me to hand off there?"
Anti-patterns
- ❌ Asking for target page / subpages / feature focus / max-tests upfront — none of that is needed for setup; only ask which page to verify, at step 4.
- ❌ Referring to
docs/ ambiguously — once Explorbot is installed, docs live at node_modules/explorbot/docs/. Never look in the skill's own folder or in a project-relative docs/.
- ❌ Hardcoding credentials in knowledge markdown or in
explorbot.config.js — always write secrets into .env, reference via ${env.X}.
- ❌ Trying to drive
explorbot start (the TUI) — agents cannot operate a TUI; if the user wants interactive mode, tell them to run it themselves.
