tossinvest-trading

tossinvest-trading is a skill for Codex from cha2hyun/tossinvest-mcp. It costs 55 tokens per session (996 once invoked), scanned A, original, MIT.

A guarded workflow for placing, changing, or cancelling Toss Securities stock orders. It supports regular market or limit orders, where a limit order sets a maximum buying or minimum selling price.

In plain words
What is it for?
Use it for explicitly approved stock buys, sells, modifications, or cancellations that meet the required symbol, side, order type, and quantity or amount details.
Why use it?
It prevents an assistant from guessing trade intent, writing before approval, exceeding limits, or repeating an uncertain order request.

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

tossinvest-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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TossInvest Trading

Use this workflow only for an explicit user-requested order action. Hermes may prefix tool names with mcp_tossinvest_; names below omit that prefix.

Non-negotiable rules

  1. Never infer an order from research, analysis, portfolio discussion, or a price target.
  2. Never request, read, transmit, log, or store the human approval token or its hash.
  3. Never split an order to evade configured limits or the KRW 100 million hard block.
  4. Never call a write tool before a matching preview has been approved outside MCP.
  5. Never call a write tool more than once for the same preview.
  6. Never automatically retry any create, modify, or cancel request.
  7. If the result is order-state-unknown, inspect order history before any further write.
  8. Treat a missing trading tool as trading disabled; do not seek another route around it.
  9. Conditional-order creation, modification, and cancellation are unsupported; never substitute a regular-order write tool or another route.

Establish exact intent

For a new order, require:

  • side: BUY or SELL
  • symbol
  • order type: LIMIT or MARKET
  • exactly one of whole-share quantity or supported USD order_amount
  • price for a limit order
  • time in force when it differs from DAY

For a modification, require the existing order ID and every proposed replacement field.

For a cancellation, require the existing order ID and an explicit request to cancel it. Do not require creation-only fields such as side or amount.

If any required intent is ambiguous, ask the user before calling a preview tool.

Create

  1. Confirm symbol identity and currency when ambiguous.
  2. Check stock warnings and the relevant market calendar.
  3. Check buying power for a buy or sellable quantity for a sell.
  4. Call preview_order exactly once with the user's stated intent.
  5. Present symbol, side, order type, quantity or amount, limit price when present, currency, estimated value, estimated KRW value, warnings, expiry, and approval_url.
  6. Explain that market-order execution price may move and that a new preview is required after expiry or material changes.
  7. Ask the user to open approval_url and approve the exact preview with the separate credential.
  8. Only after the user reports that external approval is complete, call place_order once with the preview ID.
  9. Report the returned order ID, detailed status, execution data, timestamp, and any warning.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
