Claude Trading Skills: Add Trader Habits to Claude Code

Claude trading skills are skill files for Claude Code that encode trader habits such as sizing, a pre-trade gate, and post-mortems. A Claude trader skill is the same idea. The public pack to start with is tradermonty/claude-trading-skills, listed on the Moby marketplace. The pack does not place Moby orders.

What a trader skill is

A trader skill here is a folder Claude Code can load. The folder holds a SKILL.md file that tells Claude Code how to run one habit: size a position, stop a planless trade, or write up what happened after. It is not a trading bot, and it is not an MCP server.

A Claude trading bot is a setup where Claude writes a program or stays in the loop while another system places orders. An MCP server in Claude Code is a tool connection. Moby for Claude Code is that kind of connection: Claude Code CLI calls Moby, and Moby can trade. A Claude trader skill does neither. It shapes the conversation. The order, if any, still has to go through a server you connected, inside limits that server enforces.

What is in the pack

Checked November 11, 2026 against the Moby listing and the public repo tradermonty/claude-trading-skills. The README says skills-index.yaml is the authoritative catalog. The skills directory held 74 skill folders that day, which is more than 70.

The listing names seven skills that carry over next to a Moby Agent. The index describes them as follows:

• position-sizer. Risk-based position sizes for long stock trades. Pure calculation, works offline.
• pre-trade-discipline-gate. An offline checklist that blocks planless, oversized, revenge-risk, regime-blocked, or circuit-breaker-blocked entries, and journals the result.
• drawdown-circuit-breaker. Decides whether new trade risk is allowed today, from daily loss limits, losing-streak cooldowns, and weekly or monthly drawdown halts. Offline.
• signal-postmortem. Record and analyze post-trade outcomes. Manual recording works offline. Optional price enrichment can use a Financial Modeling Prep key.
• trade-performance-coach. Review closed trades for process adherence, risk discipline, and execution quality. The index marks this one beta. It works from local notes and does not need a network key.
• backtest-expert. Guidance for systematic backtesting of a strategy you describe.
• crypto-regime-analyzer (beta). A 0 to 100 crypto regime score from free public data. The index says CoinGecko is required and needs no key.

position-sizer is written for long stock trades. The habit still applies beside a Moby proposal: it calculates a size. It does not place the Moby order.

The listing says most screeners are for US stocks and need a Financial Modeling Prep key. The README treats Financial Modeling Prep, FINVIZ Elite, and Alpaca as optional integrations for specific workflows, and the swing-opportunity path says screeners use Financial Modeling Prep. Skip those screeners. The weekly portfolio workflow in the README lists Alpaca as required, with a manual CSV as a degraded fallback, and the index marks Alpaca optional on portfolio-manager. You do not need Alpaca keys with Moby.

How to install in Claude Code CLI

These steps follow the listing, which matches the README's copy step for Claude Code. Third-party code: Moby does not audit it. Read the source before you run it.

1. Clone the repo: git clone https://github.com/tradermonty/claude-trading-skills
2. Copy the skill folders you want from skills/ into ~/.claude/skills/. Start with position-sizer, pre-trade-discipline-gate, and signal-postmortem.
3. The README says Claude Code picks up a change in a skills directory that already exists. Restart only if you created ~/.claude/skills/ during the session.
4. Skip skills that need a broker key or a Financial Modeling Prep key.

The README also documents a packaged upload for Claude's web Skills settings. This guide stays on Claude Code CLI. That is how Moby is used from Claude.

How to pair it with a Moby Agent

Run the discipline gate on a trade the agent proposes, before you say yes. Once a week, ask for a post-mortem on get_my_closed_trades. The listing gives both of those as the pairing. The skill pack still does not place Moby orders. Your Guardrails stay the hard limit. You set your agent's limits on max per trade, daily buy limit and market-cap range from the Moby app, and Moby checks them server-side on every buy your agent makes. You can ask before every trade. Moby refuses agent buys on tokens it rates red, and there is no transfer tool.

The agent trades Solana only, funded in USDC. Connect it with an agent key. The remote MCP URL is https://mcp.moby.win/mcp. The registry name is win.moby/moby. Send the key as Authorization: Bearer using MOBY_API_KEY. Hosts are Codex, Claude Code CLI, Grok CLI, and Gemini CLI (with a paid Gemini API key or enterprise access). In ChatGPT, paste your personal Moby connector URL from the app. ChatGPT: works on Business, Enterprise and Edu workspaces that allow custom MCP servers (web). The connector listing is Moby MCP.
