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 | $0.00211 | $0.04867 |
| Opus 5 | $0.00105 | $0.02433 |
| Sonnet 5 | $0.00042 | $0.00973 |
| Haiku 4.5 | $0.00021 | $0.00487 |
Grade A, and why
stream-unity scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Stream Unity - docs orchestrator for Unity Engine
Chat and Video. There is no Stream Feeds SDK for Unity (/activity-feeds/docs/unity and https://getstream.io/cli/docs/activity-feeds-unity.md both 404). If the user asks for activity feeds in Unity, say so up front and offer the alternatives (the REST/server API driven from your backend, or a platform SDK on a companion app) rather than inventing an API.
These are two separate SDKs, and almost nothing is shared. Different repos, different install mechanisms, different maturity, different supported platforms, different docs quality. There is no combined client, no shared AuthCredentials type (StreamChat.Libs.Auth.AuthCredentials and StreamVideo.Libs.Auth.AuthCredentials are distinct types in distinct assemblies), and connecting a user to one does not connect them to the other. Treat "add chat to my Unity call app" as two integrations that happen to share an API key.

| Platforms | Everything Unity targets, WebGL included | Android (ARM64), iOS, Windows x64, macOS, Linux. No WebGL, no UWP |
| Pre-built UI | None - a sample project, not components | None - a sample project, not components |
| Docs coverage | Good: nearly every page carries real Unity C# | Thin: 22 pages; several shipped capabilities have no page at all |
Neither SDK ships reusable UI. Both ship a sample project you import and read, not a component library you drop in. Every chat bubble, channel row, participant tile, and call button in the user's game is code you write. Say this before promising a screen, and run ui.md when building one.
This skill orchestrates: it gates the request against product, platform, and feature support, routes to the exact docs page, fetches it live, and applies it - while carrying the Unity-specific knowledge the docs do not have (the client's hidden DontDestroyOnLoad runner, the track-binding requirement, IL2CPP stripping, and the player settings that decide whether a build works on device at all).
Rules (read once per session): RULES.md - non-negotiable rules + Unity pitfalls. Read before writing any code.
What ships with it
5 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-unity is a skill published in the GitHub repository GetStream/agent-skills (18 stars, last pushed 3d ago), licensed Apache-2.0. It adds 211 tokens to every session and 4,867 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
self-evolve
Capture reusable patterns from a finished project and lift them into framework-level priors (contracts, modules, skeletons) that future projects inherit. Run only when the user explicitly requests self-evolution; the orchestrator executes the workflow.
artist-self-evolve
Distill stable art-generation patterns from a completed project, so future projects produce comparable assets without re-discovering the prompts. Lead-dispatched only — orchestrator invokes this skill from its self-evolve flow with a game-slug message; do not self-trigger.
vibegame-build
Run VibeGame's standard end-to-end game development workflow with reviewer gates. Use when the user wants to create a game from zero or evolve an existing game across multiple stages.
vibegame-start
Resume a VibeGame orchestrator session after vibegame start. Use at the beginning of a Claude or Codex session to inspect team runtime state, repair missing persistent members, load goal and GDD context, inspect tasks, and ask the user what to do next.
umg-mcp-authoring
Use when Codex needs to create, edit, inspect, validate, or demo UE5.8 UMG interfaces through Unreal Motion Graphics MCP/FabUmgMcp, especially target/default workflows, widget tree authoring, HLSL-backed UI materials, Sequencer widget animations, Blueprint event wiring, readback validation, or operation-trace demo…

Use when Codex needs to create, inspect, edit, delete, or validate UE5.8 material assets through Unreal Motion Graphics MCP/FabUmgMcp HLSL material tools, especially one-HLSL Custom-node authoring, UI-default versus non-UI material type selection, union-only writes, semantic outputs, hlsldelete recovery, or Material…
