Written for Claude Code: the file is CLAUDE.md. Also seen: mentions .claude-plugin; mentions Claude Code.

This is ferdousbhai/tasty-agent's own configuration. It tells Claude Code how to work on tasty-agent 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 tasty-agent 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

tasty-agent CLAUDE.md 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 23d 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.

Origin

This is a copy

100% identical to deepseek-harness CLAUDE.md — 57 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

tasty-agent

MCP server for Tastytrade account data, market data, watchlists, and order workflows. TypeScript, calling the Tastytrade REST API and DXLink directly; runs over stdio (npx tasty-agent) and on Cloudflare Workers.

Code index

  • src/tastytrade/ — standalone Tastytrade client (no MCP imports; exported as tasty-agent/tastytrade for reuse, e.g. by spicytrade): OAuth token refresh, request gate, API versions, errors, tick-size schedules, DXLink feed
  • src/server.ts — MCP tool, prompt, and schema registration
  • src/instruments.ts — instrument specs, resolution, nested option-chain cache
  • src/pricing.ts — quote-derived signed mid pricing, tick rounding, budget sizing
  • src/orders.ts — dry-run-first placement, replacement, cancellation, live orders
  • src/market.ts — REST quotes, DXLink Greeks, metrics, market status, symbol search
  • src/account.ts — compact balances, positions, orders, transactions, history
  • src/watchlists.ts — watchlist operations
  • src/broker.ts — per-request broker context, account selection, and createBroker wiring
  • src/stdio.ts — stdio entry point (npm bin)
  • src/version.ts — the server version (keep in step with package.json)
  • src/shared-load.ts — in-flight de-duplication for per-request lookups
  • src/worker/ — Cloudflare Worker entry point (bearer auth, /mcp) and the BrokerGate Durable Object
  • test/ — vitest unit tests with a fake client; integration.test.ts is credential-gated
  • commands/portfolio.md — Claude Code command surface
  • skills/trading/SKILL.md — Claude Code trading skill

Boundaries

  • Every broker call goes through TastytradeClient.request, which acquires the shared gate (two requests per second) first. Never call fetch against Tastytrade elsewhere.
  • Shared code under src/ must use only web-standard APIs so it runs on both Node and Workers; Node-only code lives in src/stdio.ts, Workers-only code in src/worker/.
  • On Workers, module state may hold settled values only (tokens, account number, chains) — never a pending promise.
  • Option chains use the 24-hour ChainCache; tests that depend on chain changes must use a fresh cache.
  • Order pricing must use pricing.ts with decimal.js, never JS floats; preserve signed debit/credit semantics. Every placement and replacement is dry-run first and refused on any dry-run warning; mutations are never retried, and an unanswered one is reported as an unknown outcome.
  • Keep MCP output compact and never replace selected projections with full API payloads.

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.
