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

callput-option-trader 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 10d ago.

The scan reads SKILL.md. This mod also ships 15 executable files (.agents/skills/mcp-builder/scripts/connections.py, .agents/skills/mcp-builder/scripts/evaluation.py, .agents/skills/skill-creator/scripts/init_skill.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Callput Option Trader (Compact)

Important Runtime Path Rule

  • <mcp_entry> is a documentation placeholder only.
  • In real OpenClaw/Claude MCP config, replace it with an absolute local path.
  • Do not keep literal <mcp_entry> in args at runtime.
  • Prefer a path without spaces to avoid launcher parsing issues.

Use this skill when the user asks for:

  • BTC/ETH options market read
  • spread entry (bullish/bearish)
  • open position management (close/settle)

One-line Intent

Market analysis -> direction setup -> tradable spread validation -> execution and position adjustment

Canonical MCP Target

  • server path: <mcp_entry>
  • do not use legacy /mcp-server/build/index.js for new agents
  • use canonical tool names: callput_* only

<mcp_entry> means the absolute local path to build/index.js.

Non-Negotiable Rules

  1. callput_get_option_chains output is for leg discovery, not direct single-leg execution.
  2. Never attempt vanilla single-leg trading via MCP.
  3. Always call callput_validate_spread before callput_request_quote.
  4. Trade only if:
    • status == "Valid"
    • details.maxTradableQuantity > 0
  5. After broadcast, always call callput_check_tx_status.
  6. If cancelled, refresh legs and repeat validation.
  7. For existing positions:
    • pre-expiry: callput_close_position
    • expired: callput_settle_position
  8. Never expose private keys in MCP output.
  9. Enforce input guards before calls:
    • callput_approve_usdc.amount > 0
    • callput_check_tx_status.tx_hash must be 32-byte hex
    • callput_close_position.address must be valid EVM address
    • callput_close_position.size > 0
    • callput_settle_position is only for expired options
    • callput_get_option_chains.expiry_date must match a listed expiry

Context Overflow Guardrails

  1. Do not keep raw chain responses in long conversation memory.
  2. Immediately compress tool output into a compact state object and discard raw payload.
  3. Keep candidate set small:
    • max 5 candidate spreads per cycle
    • max 6 Greeks lookups per cycle
  4. Always filter chain queries as tightly as possible:
    • set underlying_asset
    • set option_type when known
    • set expiry_date once target tenor is chosen
  5. Persist only minimal fields across turns:
    • asset, bias, target_expiry
    • candidate_ids (short list)
    • selected_long_leg_id, selected_short_leg_id
    • validation_status, maxTradableQuantity
    • last_tx_hash, last_tx_status
  6. During status polling, only store latest status snapshot, not full history.
  7. If context window grows, drop historical reasoning and re-bootstrap from the compact state object.

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.
