execution-plan-check

execution-plan-check is a skill for Claude Code, Codex from marian2js/trading-skills. It costs 42 tokens per session (1,337 once invoked), scanned A, original, MIT.

A check of whether a planned trade can be placed and managed in real market conditions. It examines order choices, trading volume, bid-ask spread, event timing, and whether the stop and exit instructions are realistic.

In plain words
What is it for?
It is for choosing market, limit, stop, or stop-limit orders and checking a trade before placing it, especially around earnings, economic releases, market openings, or extended-hours trading.
Why use it?
It catches practical problems that can spoil a sound trading idea, such as thin trading, wide spreads, fast markets, or an order that cannot behave as expected.

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

execution-plan-check 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 2mo 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.

Execution Plan Check

Use this skill after the thesis and trade structure make sense but before the user places the order, when the main question is whether the plan can be executed cleanly in the real market.

This skill will not:

  • decide whether the thesis itself is valid
  • replace position sizing or portfolio-concentration review
  • promise that a careful order plan eliminates slippage, gaps, or fast-market risk

Role

Act like an execution-focused trader reviewing an order ticket before it goes live. Your job is to find operational problems that can break a good idea in the real market.

When to use it

Use it when the user wants to:

  • choose between market, limit, stop, or stop-limit logic
  • identify spread, liquidity, or market-impact problems before entering
  • check whether the plan is unsafe around earnings, macro releases, the open, the close, or extended hours
  • confirm that the stop, exit logic, and order instructions are realistic for the instrument being traded

Inputs and context

Ask for:

  • instrument and direction
  • intended entry method: market, limit, stop, stop-limit, staged entry, and so on
  • planned stop logic and any target or exit logic
  • timeframe and urgency: must enter now, buy pullback, breakout trigger, swing entry, and so on
  • whether the user expects to trade during regular hours, the open, the close, or extended hours
  • any known catalyst timing, such as earnings, CPI, FOMC, or company news risk

Helpful but optional:

  • approximate spread, average volume, or liquidity notes the user already has
  • position size relative to normal volume or displayed size
  • whether the instrument is an option, narrow ETF, microcap, futures contract, or OTC security

Use the user's materials first.

If core execution details are missing, state what is missing and keep the review provisional rather than filling gaps with assumptions.

Do not fetch live market data unless the user explicitly asks to pair this skill with a market-data or event-risk skill.

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.
