What it does

Binance Spot Websocket Skill is an agent skill from holon-run/uxc. Subscribe to Binance Spot public market streams through UXC raw WebSocket support for trades, book ticker, depth, and ticker events with stream-specific guardrails.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/usage-patterns.md` and `scripts/validate.sh`).

It sits in Backend & APIs, covering Realtime and WebSockets. It works with Binance. The repository describes itself as: A unified CLI for discovering and invoking tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC. The licence is MIT.

When your agent uses it

  • Tasks that involve Realtime and WebSockets

Example prompts

  • “/binance-spot-websocket-skill”

Requirements

  • A Bash shell

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Start a subscription directly with uxc subscribe start
  2. Inspect the sink output
  3. Query runtime status
  4. Stop the job when finished

What it can do on your machine

Read from SKILL.md and the folder at commit 562d47c. 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

    Ships 1 file in scripts/ (Shell), which the agent can run.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • developers.binance.com

    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

Binance Spot Websocket Skill loads about 899 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 388 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~899
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.2k

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); the scripts in this folder are not scanned.

Binance Spot WebSocket Skill

Use this skill to run Binance Spot public market streams through uxc subscribe raw WebSocket mode.

Reuse the uxc skill for generic runtime behavior, sink handling, and event-envelope parsing.

Prerequisites

  • uxc is installed and available in PATH.
  • Network access to Binance Spot public WebSocket streams.
  • A writable sink path for NDJSON output.

Scope

This skill covers Binance Spot public market streams such as:

  • trade events
  • aggregate trade events
  • book ticker updates
  • ticker updates
  • depth updates

This skill does not cover:

  • Binance Spot REST/OpenAPI workflows
  • private user data streams
  • signed WebSocket API methods
  • margin, wallet, futures, or other non-Spot product families

Endpoint Model

Binance Spot public market streams use raw WebSocket endpoints.

  • preferred base: wss://stream.binance.com:443
  • raw stream form: wss://stream.binance.com:443/ws/<streamName>
  • combined stream form: wss://stream.binance.com:443/stream?streams=<stream1>/<stream2>

Important:

  • stream names are lowercase
  • connections are valid for up to 24 hours
  • raw stream payloads arrive directly as JSON objects
  • combined stream payloads arrive as {"stream":"...","data":{...}}

Core Workflow

  1. Start a subscription directly with uxc subscribe start:
    • uxc subscribe start wss://stream.binance.com:443/ws/btcusdt@trade --transport websocket --sink file:$HOME/.uxc/subscriptions/binance-btcusdt-trade.ndjson
  2. Inspect the sink output:
    • tail -n 5 $HOME/.uxc/subscriptions/binance-btcusdt-trade.ndjson
  3. Query runtime status:
    • uxc subscribe list
    • uxc subscribe status <job_id>
  4. Stop the job when finished:
    • uxc subscribe stop <job_id>

Common Stream Targets

  • raw trade stream:
    • btcusdt@trade
  • aggregate trade stream:
    • btcusdt@aggTrade
  • book ticker stream:
    • btcusdt@bookTicker
  • mini ticker stream:
    • btcusdt@miniTicker
  • rolling ticker stream:
    • btcusdt@ticker
  • depth stream:
    • btcusdt@depth

Runtime Validation

The following live raw WebSocket flow was validated successfully through uxc:

  • endpoint: wss://stream.binance.com:443/ws/btcusdt@trade
  • transport: --transport websocket
  • sink output:
    • open
    • repeated data events with Binance trade payloads
    • closed after stop

Observed event fields included:

  • e: "trade"
  • s: "BTCUSDT"
  • p
  • q
  • t

Guardrails

  • Keep automation on the JSON output envelope; do not use --text.
  • Parse stable event fields first: event_kind, data, meta.
  • Use wss://stream.binance.com:443 as the default public stream host; it validated more reliably than :9443 in recent runtime checks.
  • Stream names must be lowercase.
  • This skill is read-only. Do not describe it as account, order, or signed WebSocket support.
  • Combined streams are useful when one job should emit multiple markets into one sink, but downstream parsing must handle stream wrappers.
  • uxc subscribe start ... --transport websocket is the intended execution path for this skill; uxc link is not the main interface because stream identity is encoded directly in the endpoint path.
