Fishjam JS Server SDK

What it does

When your agent uses it

• Writing a Node.js / Express / Fastify / Hono / NestJS backend that talks to Fishjam
• Sets up a webhook receiver
• Runs an AI agent
• Generates livestream tokens

Example prompts

• “@fishjam-cloud/js-server-sdk”
• “FishjamClient”
• “FishjamWSNotifier”
• “/fishjam-js-server-sdk”

Requirements

• Node.js
• A credential in FISHJAM_MANAGEMENT_TOKEN

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

  Shell commands in SKILL.md call:

  • npm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • FISHJAM_MANAGEMENT_TOKEN

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fishjam JS Server SDK loads about 1.4k tokens when it runs. Until then it costs about 224 tokens; SKILL.md has 463 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~224

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

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

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.

const room = await fishjamClient.createRoom();
const { peer, peerToken } = await fishjamClient.createPeer(room.id, {
  metadata: { userId: 'user-123' },
