What it does

In the author's own words, from each skill's SKILL.md.

  • alpaca-broker-account-onboarding

    Open and manage brokerage accounts via the Alpaca Broker API — account creation, KYC/CIP, identity & disclosures, agreements, document upload (incl. W-8BEN), account status lifecycle, and account updates/closure. Use when a developer is building onboarding, KYC, or account-management flows on Alpaca in any language.

  • alpaca-broker-funding-transfers

    Move money between an Alpaca brokerage account and the EXTERNAL banking world via the Broker API — ACH relationships, wire recipient banks, classic transfers (deposits/withdrawals), the v1beta funding wallet (international/instant), transfer status lifecycles, and fees. Use when building deposit/withdrawal flows or connecting external bank accounts on Alpaca in any language. For moving cash/share…

    skills/broker-api/funding-transfers/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-integration

    Entry point for integrating with the Alpaca Broker API (plus Market Data and Trading APIs) in any programming language. Use when a developer wants to build on Alpaca — open brokerage accounts, run KYC, fund accounts, move money via journals, place orders, consume real-time event streams, or pull market data — and need to know base URLs, auth, conventions, or which focused sub-skill to use.

    skills/broker-api/integration/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-journals

    Move cash (JNLC) and securities (JNLS) BETWEEN accounts inside your own Alpaca omnibus via the Broker API — single, batch, and reverse-batch journals, the Idempotency-Key header, journal status lifecycle including corrections, and the firm/sweep-account pattern that powers instant funding and share rewards. Use for internal account-to-account movement in any language. For deposits/withdrawals to…

    skills/broker-api/journals/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-market-data

    Pull and stream US stock market data from Alpaca — REST snapshots/bars/trades/quotes, historical bars with timeframes and feeds (IEX vs SIP), the assets master list, market clock & calendar, news, and the real-time WebSocket stream. Use when building charts, quotes, price feeds, or asset metadata on Alpaca in any language.

    skills/broker-api/market-data/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-money-precision

    Handle money and numeric precision correctly with the Alpaca API — numbers-as-strings on the wire, decimals vs floats, rounding/truncation before sending amounts, fractional-share precision, and safe DB storage. Use when handling monetary amounts, order quantities, or prices in any Alpaca integration in any language.

    skills/broker-api/money-precision/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-rate-limits-resilience

    Make Alpaca API clients resilient — rate-limit header handling, HTTP 429 backoff, exponential retry, bounded concurrency/worker pools, pagination loops, batch sizing, and timeouts. Use when building robust REST clients, bulk/cron jobs, or reconciliation sweeps against Alpaca in any language.

    skills/broker-api/rate-limits-resilience/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-reconciliation-idempotency

    Keep local state correct against the Alpaca Broker API — idempotency keys, ID-keyed upserts, event snapshotting and dedup, polling rails that have no events, nightly reconciliation/heal jobs, status state-machine mapping, and handling eventual consistency and corrections. Use when designing the data-correctness layer of any Alpaca integration in any language.

    skills/broker-api/reconciliation-idempotency/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-sse-events

    Consume Alpaca Broker API real-time event streams over Server-Sent Events (SSE) — account status, journal, transfer/funding, trade, and non-trade-activity events — reliably. Covers connection, auth, replay cursors (since/since_id), heartbeats, reconnection/backoff, ordering, and idempotent processing. Use when building an event consumer for Alpaca lifecycle events in any language.

    skills/broker-api/sse-events/SKILL.md on GitHub (opens in a new tab)
  • alpaca-broker-trading-orders

    Place and manage orders on behalf of accounts via the Alpaca Broker API — order creation (qty vs notional, fractional shares, order types/TIF/classes), order status lifecycle, replace/cancel, positions, and trading-account buying power. Use when building trading, recurring-invest, or portfolio flows on Alpaca in any language.

    skills/broker-api/trading-orders/SKILL.md on GitHub (opens in a new tab)
  • alpaca-trading-backtest

    Execute deterministic, reproducible historical backtests from a start date, end date, and strategy concept using the Alpaca CLI plus agent-written workspace code. Use when the user wants to backtest a strategy, simulate historical trades, or return trades, diagnostics, and reproducibility artifacts.

    skills/trading-api/backtest/SKILL.md on GitHub (opens in a new tab)
  • alpaca-trading-paper-trading-cli

    Preview, submit, inspect, and manage Alpaca paper-trading orders using the Alpaca CLI. Supports US equities, options, and crypto. Use this skill when you want your AI agent to take a strategy signal and execute it as a paper trade through the Alpaca command-line interface.

  • alpaca-trading-paper-trading-mcp

    Preview, submit, inspect, and manage Alpaca paper-trading orders using the Alpaca Trading API MCP Server. Supports US equities, options, and crypto. Use this skill when you want your AI agent to execute paper trades through MCP tool calls — no CLI installation or direct API coding required.

  • alpaca-trading-paper-trading

    Preview, submit, inspect, and manage Alpaca paper-trading orders across US equities, options, and crypto. Use this skill when you want your AI agent to take a strategy signal — from a backtest, manual idea, or automated system — and execute it safely in your Alpaca paper-trading environment. This generic version works with any Alpaca SDK, REST API call, or agent tool that can reach the Trading AP…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
