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 | $0.00046 | $0.01463 |
| Opus 5 | $0.00023 | $0.00732 |
| Sonnet 5 | $0.00009 | $0.00293 |
| Haiku 4.5 | $0.00005 | $0.00146 |
Grade A, and why
gross-net-margin 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 13d 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.

毛利率与净利率分析
概述
这是一个诊断型技能。许多小企业老板能记账但不会分析——他们知道收入多少、花了多少,但说不清毛利率是多少、净利率是多少、为什么下降了。这个技能帮他们从"记账"升级到"看账"。
核心指标
1. 毛利率
毛利率 = (营业收入 - 营业成本) / 营业收入 × 100%
衡量产品的基本盈利能力。毛利率低意味着定价偏低或成本偏高。
2. 营业利润率
营业利润率 = 营业利润 / 营业收入 × 100%
衡量经营效率。毛利率→营业利润率之间的差距来自销售费用、管理费用、财务费用。
3. 净利率
净利率 = 净利润 / 营业收入 × 100%
衡量最终赚钱能力。包含营业外收支和所得税的影响。
分析流程
- 获取数据:从利润表取本期和对比期的数据
- 计算三个核心指标
- 同比分析:与去年同期对比
- 环比分析:与上期对比
- 行业对标:与行业平均值比较
- 驱动因素拆解:找出变化的原因
驱动因素拆解(毛利率下降的 5 种原因)
| 原因 | 信号 | 排查方向 |
|---|---|---|
| 售价下降 | 收入增速 < 销量增速 | 市场竞争加剧?被迫降价? |
| 采购成本上升 | 成本增速 > 收入增速 | 原材料涨价?供应商提价? |
| 产品结构变化 | 高毛利产品占比下降 | 产品组合恶化?新产品线毛利低? |
| 损耗增加 | 存货盘亏增多 | 库存管理问题? |
| 定价策略错误 | 长期低于同行 | 重新核算成本,建立定价模型 |

📊 盈利能力诊断报告
═══════════════════════════════════
期间:2026年1-5月 vs 2025年1-5月
本期 同期 同比变化
────────────────────────────────────────────────
毛利率 40.0% 43.2% -3.2% ↓ ⚠
营业利润率 24.0% 25.8% -1.8% ↓
净利率 22.8% 19.6% +3.2% ↑
行业参考:
毛利率 35%-45% ✓ (本公司40.0%,在行业中位数偏上)
净利率 15%-25% ✓
═══════════════════════════════════
🔍 毛利率下降 3.2% 的原因分析:
1. [主要驱动] 原材料成本上升 +12%
→ 贡献毛利率下降约 2.1%
→ 建议:与供应商谈判长期合同价格,或寻找替代材料
2. [次要驱动] 产品结构变化
→ A产品(毛利率45%)占比从60%→50%
→ B产品(毛利率35%)占比从40%→50%
→ 贡献毛利率下降约 1.1%
═══════════════════════════════════
📋 改善建议:
• 短期:审查B产品成本结构,看有无压缩空间
• 中期:重新对A产品定价,适度提价3-5%测试市场反应
• 长期:建立成本监控机制,原材料价格波动超5%自动预警
行业毛利率参考
| 行业 | 毛利率参考 | 净利率参考 |
|---|---|---|
| 软件/SaaS | 60%-85% | 10%-30% |
| 电商零售 | 15%-35% | 3%-8% |
| 餐饮 | 55%-65% | 5%-15% |
| 咨询服务 | 50%-80% | 15%-40% |
| 教育培训 | 40%-60% | 10%-25% |
| 制造业 | 15%-35% | 5%-15% |
| 建筑业 | 8%-20% | 3%-8% |
| 广告传媒 | 30%-55% | 8%-20% |
| 物流运输 | 10%-25% | 3%-10% |
以上为经验参考值,具体行业细分有差异。如果公司毛利率显著低于行业下限,说明商业模式或成本结构存在问题。
费用率分析
除了毛利率之外,还需要逐项分析各项费用率:

管理费用率 6.8% 7.2% 5%-15% ✓

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.
- 13d ago First seen · 131 lines · 46 tokens per session scan A 329f10259597
gross-net-margin is a skill published in the GitHub repository kylin985ti/china-accounting-skills (56 stars, last pushed 18d ago), licensed MIT. It adds 46 tokens to every session and 1,463 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 2026-08-30.
