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 | $0.00149 | $0.04218 |
| Opus 5 | $0.00075 | $0.02109 |
| Sonnet 5 | $0.00030 | $0.00844 |
| Haiku 4.5 | $0.00015 | $0.00422 |
Grade A, and why
stream 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 2d ago.
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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stream - skill router + CLI
This skill picks the track from the user's input. Building (web + platform) and docs go to dedicated sub-skills; CLI tasks - querying data, configuring an app, onboarding, installing skills - are handled here (see Stream CLI below), since the getstream CLI underlies every track.
Read first:
RULES.md. Non-negotiable rules apply, including the Peer skills procedure.peers.yaml(schema:peers.schema.json) is the single source of truth for peer names, Glob paths, install commands, and routing signals.Install a missing peer on demand per its policy in
peers.yaml(Glob its path, run its install command -getstream skills <name>), then invoke via theSkilltool or Read it inline. Don't callSkillbefore the Glob; it surfaces a confusing "Unknown skill" error. Do not stop after naming the track.
By task
Build or integrate Stream in a platform-specific app -> peer pack from peers.yaml (check peer signals first)
- Match user input or cwd against each peer's
signals(e.g.swift/swiftui/.xcodeproj->stream-swift;react native/expo/stream video react native->stream-react-native;unreal/.uproject/umg->stream-unreal;unity/monobehaviour/.unitypackage->stream-unity) - All peers install on demand - install if missing, then route, no prompt
- An SDK/engine signal beats an OS-target signal. When both appear, the pack that owns the SDK wins: "build an Unreal chat app for iOS" is
stream-unreal(notstream-swift), "a Unity game on Android" isstream-unity(notstream-android).ios/android/xcode/gradledescribe the build target;unity/unreal/.uproject/.unitypackage/umg/flutter/react nativedescribe the SDK. Same rule forflutter+ios. - Name the engine for game requests.
stream-unrealandstream-unityboth claim generic game phrasing (in-game chat,game chat). An explicit engine token decides it; with neither engine named and no.uproject/ProjectSettings/in the cwd, ask one short question ("Unity or Unreal?") rather than guessing. Note the capability difference that answer implies: Unity has Chat and Video, Unreal has Chat only. - Peer signals take precedence over the web rows below. A request like "add a video call to my Expo app" or "scaffold a React Native app with Stream Video" matches
stream-react-native, not the web packs - the platform token wins.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

stream is a skill published in the GitHub repository GetStream/agent-skills (18 stars, last pushed 4d ago), licensed Apache-2.0. It adds 149 tokens to every session and 4,218 once invoked, about $0.0007 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.
