What it does
Fishjam Platform is an agent skill from software-mansion-labs/skills. Fishjam platform fundamentals — domain model and auth shared by all SDKs. Covers glossary (room, peer, track, agent, streamer, viewer), the four room types (conference / audioonly / livestream / audioonlylivestream), two-tier auth (management vs peer tokens), Sandbox vs production, WebSocket-vs-webhook notifications and the 18-event taxonomy, REST endpoint list, and the end-to-end auth/join flow. Read this first for any Fishjam task. Trigger on: 'Fishjam', 'fishjam.io', 'fishjam.swmansion.com', 'fishjam…
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files (for example `auth-model.md`, `glossary.md` and `lifecycle-flow.md`).
It sits in Backend & APIs, covering Webhooks, Authentication and Realtime and WebSockets. It works with OpenAPI. The repository describes itself as: Software Mansion's set of skills for AI-assisted React Native development. The licence is MIT.
When your agent uses it
- Fishjam.swmansion.com
- Fishjam dashboard
- Management token
- Livestream room
Example prompts
- “Fishjam”
- “fishjam.io”
- “fishjam.swmansion.com”
- “/fishjam-platform”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Backend → Fishjam: createPeer(roomId) authenticated with the management token.
- Fishjam → Backend: returns { peer, peerToken }.
- Backend → Client: ships peerToken to the frontend (never the management token).
- Client → Fishjam: joinRoom({ peerToken }).
- Fishjam: completes the WebRTC handshake; the peer is now in the room.
What it can do on your machine
Read from SKILL.md and the folder at commit e3f00cd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fishjam Platform loads about 1.7k tokens when it runs. Until then it costs about 232 tokens; SKILL.md has 631 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Fishjam Platform
Software Mansion's hosted WebRTC streaming toolkit. Fishjam takes care of media servers, peer networking, and codec negotiation so applications can build video conferencing, audio chat, and one-to-many livestreaming with sub-second latency.
This sub-skill defines the domain model, auth, room types, and notifications that every SDK builds on. Read it first; then drop into the SDK sub-skill you need.
A production Fishjam app always has a backend (server SDK) + a client (client SDK). The backend mints peer tokens; the client uses them to connect. For prototyping you can skip the backend with the Sandbox API — see sandbox-vs-production.md.
Key concepts at a glance
- Room — a collection of peers exchanging tracks. Three primary room types:
conference(default, bidirectional),audio_only(75% cheaper, video silently dropped),livestream(one streamer, many viewers, <300 ms).audio_only_livestreamcombines the audio-only and livestream discounts. - Peer — a participant in a room. Can be a
webrtcclient, anagent(server-side program), or avapivoice agent. - Track — one audio or video stream from a peer (camera, mic, screen share, etc.). One peer can publish multiple tracks.
- Streamer / Viewer — livestream-room-specific peer roles (one streamer, many viewers).
- Fishjam ID — your instance identifier; goes in both backend and client config.
- Management Token — long-lived admin secret; backend only.
- Peer Token — 24h, scoped to one peer in one room; safe for clients.
Full definitions: glossary.md.
Room types
| Type | Direction | Cost | Use case |
|---|---|---|---|
conference | many ↔ many | base | Meetings, classrooms, interactive webinars |
audio_only | many ↔ many (audio only) | 75% off | Voice rooms, podcasts, town halls |
livestream | one → many | 20% off | Live events, broadcasts, sports |
audio_only_livestream is 75% off the livestream rate (equivalently, 80% off conference) — the cheapest mode for one-to-many audio.
Detail + decision matrix: room-types.md.
Auth flow (5-step sketch)
- Backend → Fishjam:
createPeer(roomId)authenticated with the management token. - Fishjam → Backend: returns
{ peer, peerToken }. - Backend → Client: ships
peerTokento the frontend (never the management token). - Client → Fishjam:
joinRoom({ peerToken }). - Fishjam: completes the WebRTC handshake; the peer is now in the room.
Full diagram + token-refresh + livestream + MoQ tokens: auth-model.md.
Sandbox vs production
- Sandbox API — no-auth HTTP backend hosted by Fishjam. For prototyping only. Generated URL must never be shipped in a production build (anyone with it can create rooms on your behalf).
- Production — your own backend running a server SDK. Required for any real-world deployment.
Migration recipe: sandbox-vs-production.md.

Notifications: WebSocket or webhook?
Both deliver the same 18-event set surfaced by the SDKs (room/peer/track/streamer/viewer/channel lifecycle — the underlying protobuf ServerMessage carries additional oneof fields the SDKs intentionally ignore). Pick by deployment shape:
- Long-lived worker, single process →
FishjamWSNotifier/FishjamNotifier(persistent socket). - Serverless, scaled out, behind a load balancer → webhooks (set
webhookUrlper room, decode binary protobuf).
Detail: notifier-vs-webhook.md and notifications-taxonomy.md.
Key rules
- Management token never leaves the backend. If it leaks, regenerate it.
- Peer tokens expire 24 hours after creation. Refresh via
refreshPeerToken/refresh_peer_tokenif you need longer. - Sandbox API URL is not a secret in the cryptographic sense, but anyone holding it can create rooms — treat it like a dev credential and rotate from the Dashboard if exposed.
- Conference is the default room type. Use
audio_onlyfor voice apps (much cheaper). Uselivestreamonly when one peer broadcasts and others only watch. - Livestream rooms accept exactly one video track + one audio track. Additional tracks are silently dropped.
