Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00112 | $0.09701 |
| Opus 5 | $0.00056 | $0.04850 |
| Sonnet 5 | $0.00022 | $0.01940 |
| Haiku 4.5 | $0.00011 | $0.00970 |
Grade A, and why
stream-flutter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 438 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stream Flutter - skill router + execution flow
Rules: Read 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) |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- yesterday First seen · 438 lines · 112 tokens per session scan A c24954afe8e3
stream-flutter is a skill published in the GitHub repository GetStream/agent-skills (18 stars, last pushed 3d ago), licensed Apache-2.0. It adds 112 tokens to every session and 9,701 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
