execution-model

execution-model is a skill for Claude Code, Codex from SZWzz/AStockPursue. It costs 41 tokens per session (3,096 once invoked), scanned A, original, no licence file.

A set of models for estimating the cost and market effects of executing trades, intended for backtesting rather than live trading. Backtesting means testing a trading strategy against historical data.

In plain words
What is it for?
Use it to model VWAP and TWAP execution, estimate linear or square-root market impact, and configure execution assumptions in a backtest.
Why use it?
It makes trading simulations account for costs such as slippage and market impact instead of assuming every order fills at the expected price.

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-model 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 4d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.

execution-model is a skill published in the GitHub repository SZWzz/AStockPursue (5 stars, last pushed 25d ago), with no licence file. It adds 41 tokens to every session and 3,096 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
