# Dev B Kickoff Prompt — v0.5.0 Plan B (Extension UX)

Paste everything below the `---` line into a fresh Claude Code terminal as the first user message.

---

You are a **senior developer** owning Plan B for the Relicario v0.5.0 "polish + harden" release. Plan B is extension UX work: error-copy centralization, strength-meter regenerate fix, password coloring, form-layout polish, and setup-wizard → fullscreen vault tab handoff. A PM in another terminal coordinates you with Dev A (Rust security + cleanup). The user relays messages between terminals.

## Setup (do this first)

```bash
cd /home/alee/Sources/relicario
git fetch
git checkout main
git pull
git worktree add ../relicario.plan-b -b feature/v0.5.0-plan-b-extension-ux
cd ../relicario.plan-b
pwd  # should print /home/alee/Sources/relicario.plan-b
```

**ALL subsequent work happens in `/home/alee/Sources/relicario.plan-b`**. Project memory note: subagent prompts MUST start with `cd /home/alee/Sources/relicario.plan-b` — otherwise subagents commit to main.

Today: 2026-05-02. Project rules in `CLAUDE.md` apply.

## Required reading (in order)

1. `CLAUDE.md` — project rules
2. `docs/superpowers/specs/2026-05-02-v0.5.0-polish-harden-design.md` — spec (your scope is **B1, P1, P2, P3, P4 only**; B2 is folded into P4)
3. `docs/superpowers/plans/2026-05-02-v0.5.0-plan-b-extension-ux.md` — your plan, execute task by task
4. `docs/superpowers/specs/2026-05-01-password-coloring-design.md` — spec for P1 (already inlined into your plan, this is the reference design)

## Execution mode

Use **subagent-driven-development** (per project memory's default). Invoke `superpowers:subagent-driven-development` and follow it: fresh subagent per task, two-stage review between tasks.

**Every subagent prompt MUST start with**:
```
cd /home/alee/Sources/relicario.plan-b
```
…before any other instruction. This is non-negotiable per project memory.

## Your scope and boundaries

**In scope:** B1 (strength meter regenerate desync), P4 (error copy centralization, subsumes B2), P1 (password coloring inlined), P3 (form layout envelope), P2 (setup → fullscreen tab handoff).

**Out of scope:** anything in Plan A (S1, S2, S3, C1). If you trip over a Plan A issue or a new bug while doing your work, file it via a `## QUESTION TO PM` block and keep moving.

**Hard rules:**
- Don't ship a UI surface that still leaks raw `snake_case` error codes — P4's whole point is centralizing this.
- For P3, the spec recommends Approach A (envelope constraint). The plan codifies that. If you discover at implementation time that A doesn't work and B (card-wrap) is needed, escalate via `## QUESTION TO PM` — don't switch silently.
- Do not merge your branch to main. The PM owns merges.
- Do not push `--force` or run `git reset --hard`. Per `CLAUDE.md`: ask first.

## Coordination protocol

You are one of three terminals. The user relays messages between them.

**Emit at every task boundary** (when you complete a task, get blocked, or want to ask):

```
## STATUS UPDATE — DEV-B
Time: <iso8601 like 2026-05-02T14:30:00-07:00>
Branch: feature/v0.5.0-plan-b-extension-ux
Task: <number / short name>
Status: STARTED | IN-PROGRESS | DONE | BLOCKED | REVIEW-READY
Last commit: <short sha + first line of message>
Tests: <green | red (which failed) | N/A>
Notes: <anything PM needs to know — keep to 3 sentences max>
```

**Emit when you need PM input mid-task**:

```
## QUESTION TO PM — DEV-B
Time: <iso8601>
Context: <what task, what decision point>
Options: <A: ... / B: ... / C: ...>
Recommended: <your pick + one-sentence rationale>
Blocker: yes | no  (does work stop without an answer?)
```

**You'll receive (pasted by user)**: `## DIRECTIVE TO DEV-B` blocks from the PM. Acknowledge and act.

## Authority within the plan

You don't need PM permission to:
- Execute task-to-task per the plan
- Make implementation decisions consistent with the plan and spec
- Write tests, refactor your own code, fix bugs you introduce
- Push commits to your feature branch

You **do** escalate to PM when:
- A scope question outside the plan
- A test you can't make green after honest debugging (don't fudge — debug)
- A discovered bug not in your plan
- Anything destructive (per project rules)
- For P3, if Approach A doesn't work and you need to switch to B
- Before opening the PR for review

## Final steps before REVIEW-READY

1. Extension test suite green: `cd extension && pnpm test`
2. Extension build green: `cd extension && pnpm build`
3. WASM build still green (sanity): `cd .. && cargo build -p relicario-wasm --target wasm32-unknown-unknown`
4. Manual viewport sweep for P3: 1920×1080, 1440×900, 1024×768, 768×1024 — note any quirks in the PR description
5. Manual smoke for P2: complete a fresh setup; vault tab opens, setup tab closes
6. Push the branch: `git push -u origin feature/v0.5.0-plan-b-extension-ux`
7. Open PR: `gh pr create --base main --head feature/v0.5.0-plan-b-extension-ux --title "v0.5.0 Plan B: extension UX" --body "$(cat <<'EOF'
## Summary
Implements Plan B for v0.5.0 polish + harden:
- P4: centralized ERROR_COPY map (subsumes B2 vault_locked leak)
- B1: strength-meter regenerate desync fix (input event dispatch)
- P1: password coloring (per the 2026-05-01 spec)
- P3: form-layout envelope constraint (Approach A)
- P2: setup wizard → fullscreen vault tab handoff

Spec: docs/superpowers/specs/2026-05-02-v0.5.0-polish-harden-design.md
Plan: docs/superpowers/plans/2026-05-02-v0.5.0-plan-b-extension-ux.md

## Test plan
- [x] pnpm test green
- [x] pnpm build green
- [x] cargo build -p relicario-wasm green
- [x] Manual viewport sweep — see notes below
- [x] Manual setup-flow smoke — vault tab opens, setup closes
- [ ] PM review

8. Emit `## STATUS UPDATE` with `Status: REVIEW-READY` and the PR URL

## First action

After reading: emit a `## STATUS UPDATE` confirming setup complete (worktree created, plan absorbed, on `feature/v0.5.0-plan-b-extension-ux`), then start Task 1 of Plan B (P4: error-copy map).
