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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00768 |
| Opus 5 | $0.00028 | $0.00384 |
| Sonnet 5 | $0.00011 | $0.00154 |
| Haiku 4.5 | $0.00006 | $0.00077 |
Grade A, and why
northbound-flow 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 5d 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
北向资金
何时使用
用户要北向/互联互通资金观察。必须先做字段可用性探测：工具未返回北向净买等字段时，禁止编造，改为说明缺口并降级到可得的资金/市场动态。边界：vs @skill:liquidity-map——后者做个股/板块资金流与龙虎榜热力（非 L2）；本技能专盯沪深股通/北向口径；全市场开市简报用 @skill:morning-market-brief。
分析架构（投研方法）
- 问题/假设：北向资金近期方向如何？与标的/市场是否同向？
- 证据清单：
get_cn_market_special、get_market_dynamics、可选个股资金流 - 多维交叉验证：北向字段 vs 大盘动态；个股资金流≠北向
- 事实 | 假设 | 推断 分栏
数据维度
| 维度 | 取数方向 | 缺失时 |
|---|---|---|
| 市场特殊/北向 | get_cn_market_special |
诚实缺口：写「未返回北向字段」，禁止编造 |
| 市场动态 | get_market_dynamics |
降级说明 |
| 个股资金 | get_instrument_money_flow |
标明≠北向 |
| 快照 | get_instrument_snapshot |
可省略 |
| 交付 | list_web_vendor → create_web |
可跳过口头要点 |
步骤
- 探测
get_cn_market_special等是否含北向相关字段。 - 有则制表，无则横幅声明缺口——绝不编造净买额。
- 可选对照大盘动态/个股资金（须标注口径不同）。
- 交付网页（默认）。
网页报告建议目录
- 数据可用性声明
- 北向/互联互通事实表（或缺口说明）
- 口径说明（字段定义与统计窗口）
- 与个股资金流差异（≠主力/龙虎榜口径）
- 市场对照与事实 / 推断分栏
- 免责声明
禁止
- 禁止编造北向净买入/净卖出数字
- 把个股主力资金流写成北向
- 荐股；禁止无交付就结束
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.
- 5d ago First seen · 61 lines · 57 tokens per session scan A 3a3c282d5e4d
northbound-flow is a skill published in the GitHub repository Travisun/Opptrix (230 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 768 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 2026-09-03.
