name: electron-developer

description: Implement or fix small-to-medium Electron apps (main, preload, renderer, IPC, packaging). Use for isolated Electron work or when invoking /electron-developer.

## STOP - Read before ANY tool call

1. Read `{{GUARDRAILS_PATH}}`

2. Read `_shared/sdd-artifacts/SESSION.md`; load session-state for `$Cwd`

3. If the relevant gate is not approved: **STOP** - ask user **(pt-BR)** - do **NOT** Write/Shell

4. SDD/develop skills: after **ONE** step/task, **STOP** session - handoff only

5. This skill body is **English**; user-facing prompts may be **(pt-BR)**

### Step -1 - Gate check (report in chat before continuing)

```

Gate check:

[ ] guardrails.mdc read

[ ] SESSION.md read; session-state loaded

[ ] User confirmed current action (sim)

-> If any unchecked: STOP

```

+ # Skill: electron-developer

## Trigger

Use when user asks for `/electron-developer`, `electron fix`, or a small isolated Electron implementation.

## Outcome

Working main/preload/renderer changes, validated with build and documented smoke (app launch), with optional handoff to `/commit`.

- ## Renderer stack (orchestration)

- Detect renderer framework from `package.json`:

- | Dependency | Lazy-load guidelines |

- |------------|---------------------|

- | `react` | `react-guidelines/` |

- | `vue` | `vue-guidelines/` |

- | Neither | `javascript-guidelines/`, `html-css-guidelines/` |

- **Stay in `electron-developer` identity** - load stack guidelines for UI patterns only; do not switch to `react-developer` / `vue-developer`.

- ## When to escalate to SDD

- Recommend `sdd-spec` -> `sdd-plan` -> `sdd-develop` if two or more apply: main+renderer+packaging overhaul, auto-update pipeline, cross-repo impact, 10+ files, or existing approved PLAN.

- ## DESIGN-BRIEF acceptance

- If `docs/DESIGN-BRIEF.md` or `docs/design/DESIGN-BRIEF.md` exists, treat it as the acceptance source. Map sections to renderer UI; do **not** reinterpret visual decisions. Implement **one session scope** from section 10 only.

- If the task is net-new UI without a brief, recommend `/impeccable shape` in a **new session** before implementing.

+ **Never by default:** do not preload all `references/*.md`. do not preload the full `electron-guidelines/` pack plus all renderer stacks. Load security first when IPC/CSP changes; fan-out to main/preload/IPC/packaging only for that surface. Do not dump full stack guideline packs or memory-bank. Load **one** section per Process step (`SKILL-REFERENCE-RETRIEVAL.md`).

**Progressive load:** DESIGN-BRIEF / workspace context first; then the Electron row for the active concern; open one renderer pack file only when editing renderer UI.

+ ## Reference routing

+ | Situation | Path |

+ |-----------|------|

+ | Scope / SDD escalation / design brief | `references/scope.md` |

+ | Implement flow | `references/execute-flow.md` |

+ | Must not (full) | `references/must-not.md` |

## Process

+ Read `references/<section>.md` for procedural detail — **not** full `reference.md`.

### Step -1b - Caveman Mode (Full cap)

1. Read `{{SDD_ROOT}}/preferences.json` (create `{ "caveman_mode": false, "caveman_level": "full" }` if missing).

2. If `caveman_mode` is false: continue without compression.

3. If true: load `{{TOOLKIT_ROOT}}/skills/_shared/caveman/CAVEMAN.md`; apply **Full** participation cap + prefs `caveman_level` (Lite skills never escalate); show once: `[Caveman] Modo ativo (respostas compactas, level={effective}). Digite caveman off para desativar.`

5. Auto-Clarity + never-compress gates/drafts/paths per `CAVEMAN.md`.

- ### Subagent-first (before implement)

- Classify complexity → consult capability `subagents` → if medium/complex and `native`: spawn ≤2 children (scoped **paths** + **receipt**); **trivial** stays **in-parent**; if `subagents=none` or Task unavailable → **fallback** **in-parent** (never hard-fail). Load `SPAWN.md` + `subagent-first.md`; do not paste guidelines into child prompts.

- ### 0. Workspace

- Confirm Electron project (`electron`, `electron-builder`, or `electron-vite` in `package.json`). Identify main/preload/renderer entry points.

- ### 1. Guidelines

- Load Electron + renderer guidelines for this task. Review security defaults before IPC changes.

- ### 2. Branch

- Use `feature/<slug>` or `feat/<id>`. Never commit on `main`/`master`/`develop`.

- ### 3. Micro-plan

- Define 3-7 concrete tasks; checkpoint context at >= 40%.

- ### 4. Implement

- Main/preload/renderer separation, typed IPC, contextIsolation. Match existing electron-vite or electron-builder layout.

- ### 5. Tests

- Unit tests for pure modules; manual smoke: app launches, changed flow works.

- ### 6. Validate

- ```bash

- npm run build

- ```

- Document smoke steps in chat (launch app, exercise changed feature).

- ### 7. Handoff

+ ### 0. Scope

+ Follow `references/scope.md` (SDD escalation, design brief / host detection when present).

- Offer `/commit`. Do not commit automatically.

+ ### 1. Execute

+ Follow `references/execute-flow.md` (subagent-first, workspace → guidelines → branch → implement → tests → handoff).

## Must not

- - Paste guideline packs into child prompts (pass scoped **paths** + require **receipt** only)

- - Spawn children for **trivial** work (keep **in-parent**)

- - Hard-fail when capability `subagents` is `none` or Task is unavailable (use **fallback** **in-parent**)

- - Enable `nodeIntegration: true` in renderer without explicit user approval

- - Expose raw `ipcRenderer` on `window` without contextBridge

- - Auto-commit or auto-PR

- - Leave AI traces in code or identifiers

+ Enforce the full list in `references/must-not.md`. Critical: no guideline dumps into children; no auto-commit; lazy-load stack guidelines only — never dump full packs or memory-bank.

## Handoff

| Situation | Next |

|-----------|------|

| Commit | `/commit` |

| Review | `/code-review` |

| Scope grew | `sdd-spec` -> `sdd-plan` -> `sdd-develop` |

| Missing design brief | `/impeccable shape` (new session) |
