Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00053 | $0.00926 |
| Opus 5 | $0.00026 | $0.00463 |
| Sonnet 5 | $0.00011 | $0.00185 |
| Haiku 4.5 | $0.00005 | $0.00093 |
Grade A, and why
execution-cost 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 2d 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.
What it actually says
交易成本
何时使用
用户要理解 交易/再平衡的成本与执行摩擦(佣金、印花税、滑点粗估、冲击概念),而非下单或完整 TCA 报告。边界:再平衡差额用 @skill:rebalance;压力用 @skill:stress-test。无 Level-2 / 专业 TCA 数据源——必须设诚实缺口专节,禁止假装机构级 TCA。
分析架构(投研方法)
- 问题/假设:在用户给定费率与规模假设下,成本上界大概多少?哪些摩擦未建模?
- 证据清单:持仓规模、用户费率/滑点假设、拟交易名义金额
- 多维交叉验证:费率假设敏感性;规模相对日均成交(若用户提供)
- 结论与不确定:计算结果依赖假设;非成交回报
- 风险与缺口:无 L2 TCA、无真实成交明细、无盘口
- 事实 | 假设 | 推断 分栏强制
数据维度
| 维度 | 取数方向 | 缺失时 |
|---|---|---|
| 持仓/规模上下文 | get_portfolio_holdings / portfolio_summary |
仅按用户名义金额估算 |
| 费率与滑点假设 | ask_user(必填关键假设) |
给框架表,不做假精确 TCA |
| 拟交易清单 | 用户 / 再平衡会话结果 | ask_user |
| L2 / TCA | 不可用 | 诚实缺口:写明无法做机构 TCA |
| 交付 | list_web_vendor → create_web |
用户只要口头要点时可跳过 |
步骤
- 确认分析对象:拟交易名义金额或再平衡差额。
ask_user收集费率、税、滑点粗假设;禁止填「市场默认精确值」冒充事实。- 估算可算部分(佣金/税/假设滑点);列出未建模项。
- 诚实缺口专节:无 L2、无成交回报归因、无券商账单。
- 交付网页(默认):
list_web_vendor→create_web。
网页报告建议目录
- 范围、时效与数据局限声明
- 输入假设表(费率/滑点/规模)
- 可估算成本表
- 敏感性(假设变动)
- 诚实缺口:无 L2 TCA
- 事实 | 假设 | 推断分栏
- 免责声明(非成交建议;非券商账单)
禁止
- 假装完整 TCA / L2 冲击模型
- 荐股或保证「成本只有 X」
- 禁止无交付就结束(默认须有 web 产物,除非用户明确只要口头要点)
- 隐瞒不可用数据
- assumption / not-feasible 须诚实降级
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-cost is a skill published in the GitHub repository Travisun/Opptrix (224 stars, last pushed 4d ago), licensed Apache-2.0. It adds 53 tokens to every session and 926 once invoked, about $0.0003 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 2026-08-30.
