wizard

A wizard is a bash script that walks a human through a manual procedure one step at a time. It opens each URL, says exactly what to click and copy, captures the values, writes them where they belong, verifies what it can, and shows how much is left.

It exists for the class of work that blocks agents outright: a dashboard behind someone's SSO, a registrar's DNS panel, a secret that must never enter an agent's context. The alternative is a wall of numbered prose the human loses their place in on step four.

The UX is already solved by template.sh — progress with time remaining, confirmation gates, cross-platform URL opening, hidden secret entry, idempotent .env upserts, gh secret writes, live verification, and a closing summary of what still needs doing by hand. Your job is to scope the procedure and author its stages. The library above the STAGES marker is identical in every wizard; that consistency is the point.

A wizard is ephemeral by default — built for one run, written to a scratch or scripts/ path, deleted when the job is done. Commit it only when the repo wants a repeatable setup path, and then link it from the README so the next person runs the script instead of re-deriving it.

1. Scope the procedure

Work out every manual step and every value captured along the way. Read the repo first — do not interview cold:

• Setup: .env, .env.example, README, docker-compose*, framework config, and .github/workflows/* (every secrets.* and vars.* reference is a value the wizard must produce).
• Migration or cutover: the current state, the target state, and every irreversible action between them.

Then show the decider the ordered stage list and the values each produces, and confirm. They may add, drop, or reorder.

Done when: every stage is named in order, and for each value you know (a) where the human gets it, (b) where it is written — .env, a CI secret, both, or nowhere, since some stages are pure actions — and (c) whether it is secret.

2. Map each stage's journey

For each stage, write the exact path a human follows: which URL, what to do there, where the value appears, which variable it fills — "Dashboard → Developers → API keys → Reveal test key → copy".

Where you do not know the current UI or the exact command, say so and ask, or check the vendor's docs. Inventing a menu path that does not exist is worse than admitting the gap: the human trusts the script and burns ten minutes hunting for a button that was never there. This is the single most common way a wizard fails.

Done when: every stage traces to concrete instructions a stranger could follow, and every uncertain path is either verified against primary sources or explicitly flagged in the script.

3. Author the wizard

Copy template.sh to the target path and replace the example stage with one stage per step, in dependency order. Use the library helpers — require, stage, say/step/note, open_url, ask/ask_secret, write_env, set_secret/set_var, check, pause/confirm, manual — and set TOTAL_STAGES and TOTAL_MINUTES to honest estimates.

Hold the bar the template sets:

• Open the URL before asking for the value it produces.
• ask_secret for anything secret; write_env for every persisted value; set_secret only for what CI actually needs.
• confirm before any irreversible action.
• check wherever a manual step has an observable result — a DNS record that should resolve, an endpoint that should answer. A step the script can verify is a step the human cannot silently get wrong.
• manual for anything the script cannot do, so it lands in the closing summary instead of being forgotten.
• One focused task per stage. Each stage clears the screen, so anything the human still needs must not have scrolled away.
• Never hand-edit the library above the marker.

4. Verify and hand off

• bash -n <script>, and shellcheck if available.
• chmod +x <script>.
• Do not run it end to end yourself — it opens browsers and blocks on human input. Trace it statically: every value from step 1 is captured and lands where step 1 said, and every set_secret name matches a secrets.* reference in CI exactly.
• Tell the human how to run it, and what they will need open before they start (accounts, logins, a payment method).

Done when (checkable — verify each line before reporting complete)

• bash -n passes and the script is executable.
• Every value identified in step 1 is captured by a stage and written where step 1 said it goes.
• Every set_secret name matches a CI reference exactly — checked against .github/workflows/*, not from memory.
• Every stage that has an observable result carries a check; everything the script cannot do carries a manual.
• TOTAL_STAGES equals the number of stage calls, and TOTAL_MINUTES is an honest sum.
• No invented UI paths: every menu path is either verified against primary sources or flagged in the script as unverified.
