What this skill does

# Stream Flutter - skill router + execution flow

**Rules:** Read **[`RULES.md`](RULES.md)** once per session - every non-negotiable rule is stated there, nowhere else.

This file is the **single entrypoint**: intent classification, local project detection, and module pointers for Stream work in Flutter apps.

---

## Step 0: Intent classifier (mandatory first - never skip)

Before any tool call, decide the **track** from the user's input alone - no probes first.

### Signals -> track

| Signal in user input | Track |
|---|---|
| Explicit package/widget token: `stream_chat_flutter`, `StreamChannelListView`, `StreamMessageListView`, `StreamChatClient`, etc. | **C - Reference lookup** |
| Explicit video token: `stream_video_flutter`, `StreamCallContainer`, `StreamVideo`, `StreamVideoRenderer`, `goLive`, `stopLive`, `livestream` call type | **C - Reference lookup** |
| Explicit feeds token: `stream_feed`, `stream_feed_flutter_core`, `StreamFeedClient`, `FlatFeedCore`, `FlatFeed`, `FeedBloc`, `activity feed`, `feeds flutter` | **C - Reference lookup** |
| Words "docs" or "documentation" around Stream Flutter work | **C - Reference lookup** |
| "How do I {X} in Flutter?", "What does {widget/method} do?" | **C - Reference lookup** |
| "Build me a new Flutter app", "create a Flutter chat app" + Stream | **A - New app** |
| "Build a Flutter video call app", "create a livestream app in Flutter" | **A - New app** (load `VIDEO-FLUTTER.md` + `VIDEO-FLUTTER-blueprints.md` or `LIVESTREAM-FLUTTER.md` + `LIVESTREAM-FLUTTER-blueprints.md`) |
| "Build a Flutter feeds app", "create an activity feed app", "build a social feed in Flutter", "create a Twitter/Instagram clone" | **A - New app** (load `FEEDS-FLUTTER.md` + `FEEDS-FLUTTER-blueprints.md`; use Twitter-style UI unless the user explicitly specifies otherwise) |
| "Add/integrate Stream into this app", "wire Chat into my Flutter project" | **B - Existing app** |
| "Add video calling to my Flutter app", "integrate Stream Video into my existing app" | **B - Existing app** (load `VIDEO-FLUTTER.md` + `VIDEO-FLUTTER-blueprints.md`) |
| "Add a feed to my Flutter app", "integrate Stream Feeds into my existing app", "add activity feed" | **B - Existing app** (load `FEEDS-FLUTTER.md` + `FEEDS-FLUTTER-blueprints.md`; use Twitter-style UI unless the user explicitly specifies otherwise) |
| "Install Stream packages", "set up Stream in Flutter", "wire auth/token" with no broader feature request | **D - Bootstrap / setup** |
| Bare `/stream-flutter` with no args | List the tracks briefly and wait |

### Disambiguation flow

If the request is ambiguous between **build/integrate** and **reference lookup**, ask one short question and wait:

> Do you want me to wire this into the project, or just map the Flutter SDK pattern and widgets?

### After classification

- **Tracks A, B, D** -> run **Project signals** once per session, then continue in [`builder.md`](builder.md) and [`sdk.md`](sdk.md).
- **Track C** -> skip the probe if the product + package are explicit. Only run it on demand if the SDK layer is ambiguous.

## Step 0.5: Credentials, token, and seed data (tracks A, B, D only)

Run this once per session, right after intent classification, before the Project signals probe.

### Goal

Collect the Stream **API key**, a **user token**, and optionally seed channels or calls - all before touching code - so the app has real data to show from the first run.

### Single upfront question (ask exactly once, then act immediately)

Post **one message** asking all relevant things together. Do not split into multiple rounds.

**For Chat projects:**

> To wire everything up with real data, I need a few quick answers:
>
> 1. **Credentials** - Should I fetch your API key from the dashboard and generate a token via the Stream CLI, or will you paste them yourself?
> 2. **Token expiry** - If I'm generating the token: should it expire? (e.g. `1h`, `1d`, `30m`) or never expire?
> 3. **Seed channels** - Should I pre-create a few channels with random usernames so the app has something to show immediately?
>
> If you want to handle everything yourself, just paste your API key and token and tell me whether to seed channels.

**For Video projects** (calls are ephemeral - no seeding needed):

> To wire everything up, I need a couple of quick answers:
>
> 1. **Credentials** - Should I fetch your API key from the dashboard and generate a token via the Stream CLI, or will you paste them yourself?
> 2. **Token expiry** - If I'm generating the token: should it expire? (e.g. `1h`, `1d`, `30m`) or never expire?
>
> If you want to handle everything yourself, just paste your API key and token.

**For Feeds projects** (no pre-built UI; feed groups required):

Ask **one message** with all setup questions together — do not split into rounds:

> To wire everything up, I need a few quick answers:
>
> 1. **Credentials** - Should I fetch your API key from the dashboard and generate a token via the Stream CLI, or will you paste them yourself?
> 2. **Token expiry** - If I'm generating the token: should it expire? (e.g. `1h`, `1d`, `30m`) or never expire?
> 3. **Feed groups** - I need to create 3 feed groups in your Stream project (user, timeline, notification). Should I set these up automatically, or have you already created them?
> 4. **Seed posts** - Should I add a few sample posts so the feed has content from the first run?
>
> If you want to handle credentials yourself, just paste your API key and token.

Once the user replies, execute all steps without pausing. For feed groups, if the user said "set up automatically":

```bash
stream api CreateFeedGroup --body '{"id": "user", "type": "flat"}'
stream api CreateFeedGroup --body '{"id": "timeline", "type": "flat"}'
stream api CreateFeedGroup --body '{"id": "notification", "type": "notification"}'
```

If the CLI commands fail (the Feeds API may use different endpoints than Chat), tell the user once:
> Please create these in Stream Dashboard → Activity Feeds → Feed Groups: `user` (Flat), `timeline` (Flat), `notification` (Notification).

For Feeds projects, always generate two separate helpers in `main` after `connect()`:
1. `_setupFollows(client)` — **always called, unconditionally.** Makes `timeline` follow `user` so the user's own posts appear there. Do not merge this into seed logic — once seed data exists the guard returns early and the follow call never runs.
2. `_seedPosts(client)` — only if the user said yes to seeding. Adds sample activities and exits early if data already exists.

See [`references/FEEDS-FLUTTER.md`](references/FEEDS-FLUTTER.md) for both implementations.

The package is `stream_feeds: ^0.5.1` — not the deprecated `stream_feed` or `stream_feed_flutter_core`.

### After the user replies - act without further prompting

Once the user answers, execute all CLI steps in sequence **without pausing for confirmation between them**. Narrate each step briefly as you go (one line per action), but do not stop to ask "shall I continue?".

#### Step A - API key

```bash
stream keys
```

This prints the API key and copies the secret to clipboard. Extract the `API Key:` field from the output. Hold it in context. If the command returns a 401 error, the CLI session has expired — run `stream auth logout && stream auth login` to re-authenticate, then retry.

#### Step B - Token

```bash
# Never-expiring
stream token <user_id>

# Expiring
stream token <user_id> --ttl <duration>
```

Hold the token in context. Use it (and the API key) in every code snippet - no placeholder strings.

#### Step C - Seed channels (only if the user said yes)

Create 3-5 channels with random realistic usernames. Use `messaging` as the default channel type.

**Sub-step C1 — upsert all users** (seed users + the token user):

```bash
stream api UpdateUsers --body '{
  "users": {
    "<token_user_id>": {"id": "<token_user_id>", "name": "<Display Name>"},
    "alice": {"id": "alice", "name": "Alice"},
    "bob":   {"id": "bob",   "name"
