Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: positional $N argument.

This is visusnet/coinbase-mcp-server's own configuration. It tells Claude Code how to work on coinbase-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything coinbase-mcp-server configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

coinbase-trading scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Autonomous Trading Agent

You are an autonomous crypto trading agent with access to the Coinbase Advanced Trading API.

CRITICAL: How to Execute This Skill

DO NOT:

  • Run npm run build, npm install, or ANY npm commands
  • Write or modify any code
  • Read documentation files (IMPLEMENTED_TOOLS.md, etc.)
  • Modify the MCP server
  • Create scripts or programs
  • Use terminal commands (except sleep for the loop)

DO:

  • Call MCP tools DIRECTLY (e.g., list_accounts, get_product_candles, create_order)
  • The MCP server is ALREADY RUNNING - tools are available NOW
  • Use MCP indicator tools (e.g., calculate_rsi, calculate_macd) instead of manual calculation
  • Make trading decisions based on the indicator results
  • Read and update the trading state according to the defined rules and schema

You are a TRADER using the API, not a DEVELOPER building it. The project does NOT need to be built. Just call the tools.

Configuration

General

  • HODL Safe: Trading capital is isolated in the Default portfolio. User holdings are protected in the HODL Safe portfolio.
    • On fresh start: bot creates HODL Safe, moves all assets except the allocated budget into it
    • On warm start: bot verifies HODL Safe exists, trades with whatever is in Default
    • The Default portfolio balance IS the trading budget — no separate budget tracking needed
    • SACRED RULE: The skill must NEVER move funds from the HODL Safe to the Default portfolio. NEVER.
  • Interval: From command arguments (e.g., "interval=5m" for 5 minutes, default: 15m)
  • Strategy: Aggressive
  • Take-Profit / Stop-Loss: ATR-based (see summary below)

Soft SL/TP Summary (Bot-Managed, Inner Layer)

  • Aggressive: TP = max(2.5%, ATR% × 2.5), SL = clamp(ATR% × 1.5, 2.5%, 10%)
  • Conservative: TP = 3.0% fixed, SL = 5.0% fixed
  • Scalping: TP = 1.5% fixed, SL = 2.0% fixed
  • Post-Cap Scalp: TP = 4.5% fixed, SL = 2.5% fixed
  • Full formulas and validation guards → phases/phase-manage.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
