What it does

Sealeap Suanni Amazon Unit Profit Breakeven is an agent skill from xjli360/sealeap-amazon-skills. Build a per-unit profit model for an FBA product from selling price, sourcing cost, first-mile cost, fulfilment fee, referral fee and other fees, and derive gross margin, net payout and the break-even price under alternative logistics routes. Use for 一单能赚多少、利润怎么算、保本价、盈亏平衡价、毛利率、店铺回款、海运空运利润对比、最多能降到多少钱. Do not use to set final prices or promotions without current fee schedules and verified cost inputs.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/mcp-data-plan.md` and `references/playbook.md`).

It works with Model Context Protocol. The repository describes itself as: Reusable Agent Skills for Amazon product research, listings, advertising, inventory, and operations. The licence is MIT.

When your agent uses it

  • 一单能赚多少、利润怎么算、保本价、盈亏平衡价、毛利率、店铺回款、海运空运利润对比、最多能降到多少钱
  • Set final prices
  • Promotions without current fee schedules and verified cost inputs

Example prompts

  • “/sealeap-suanni-amazon-unit-profit-breakeven”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. 诊断:读取现状、证据和缺口,不生成线上写入动作。
  2. 方案草案:输出可审核的结构、参数范围、实验和回退值。
  3. 执行准备:只生成待批准变更表或 API/控制台操作草案。
  4. 已批准执行:仅对用户在当前会话明确批准的对象和字段执行,并立即回读核验。

What it can do on your machine

Read from SKILL.md and the folder at commit 497d4b8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sealeap Suanni Amazon Unit Profit Breakeven loads about 757 tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 153 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~757
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Amazon FBA 单品利润与保本价测算

目标

Build a per-unit profit model for an FBA product from selling price, sourcing cost, first-mile cost, fulfilment fee, referral fee and other fees, and derive gross margin, net payout and the break-even price under alternative logistics routes.

不可妥协的边界

  • 当前 Amazon 官方政策、账户资格、站点字段和一方数据优先于本 Skill 的经验框架。
  • 第三方数据一律标为估算或前台观测,不得写成 Amazon 一方事实。
  • 默认只读诊断和草案;任何广告、Listing、库存、促销或外部系统写操作都需逐项展示并取得明确批准。
  • 一次实验只改变一个主要变量,并记录基线、样本、成功、停止和回退条件。
  • 不得复制来源材料或竞品表达;输出必须按当前任务重新组织并可由现有证据支撑。
  • 来源使用的类目佣金比例、汇率、配送费与头程单价都是示例数值,正式测算以当前站点费率表、类目佣金表和实际报价为准。
  • “首批小批量仓储费可忽略、不打广告就没有广告费”是简化假设,只适合首单可行性测算;正式经营模型必须计入广告、仓储、退货与促销折扣。
  • 保本价只覆盖已列出的成本项,未列项(退货、广告、超龄库存、汇兑损失)会让真实盈亏点高于计算值;以当前账户的实际费用结构校准。
  • 只在 marketplace、币种、时间窗一致时比较不同方案;不同来源的成本口径冲突时保留各自口径并说明,不取平均。

先判断任务模式

  1. 诊断:读取现状、证据和缺口,不生成线上写入动作。
  2. 方案草案:输出可审核的结构、参数范围、实验和回退值。
  3. 执行准备:只生成待批准变更表或 API/控制台操作草案。
  4. 已批准执行:仅对用户在当前会话明确批准的对象和字段执行,并立即回读核验。

用户未指定时采用“诊断”。

开始前要拿到

  • 目标 marketplace、类目、价格带、上架时间与运营模式
  • 候选品与同购买意图可比样本的销量、评论、价格和上架时间
  • 关键词需求、历史趋势、广告依赖、同款密度和品牌集中度
  • 采购、头程、平台费、退货、仓储、交期和合规/IP 基础信息

缺失项必须标为 NEEDS_EVIDENCE;不得猜数字、补属性或把不同站点、ASIN、变体、币种和时间窗混在一起。

工作流

先读取 references/playbook.md,确认该方法适用于当前对象。按以下顺序执行:

  1. 定义测算售价:用目标市场同类产品的公开售价区间与自身定位确定,并注明是拟定价还是现价;采购价按含税含运的实际到手价,用当期汇率折算成售价币种并记录汇率取值日。
  2. 逐项填入每单变动成本:FBA 配送费(按尺寸分段与当前费率表)、头程每单位成本(按计费重与所选渠道)、平台佣金(按当前类目费率与价格分段计算,不同类目与价格段比例不同)、以及包装、标签、退货等已知的单位成本。
  3. 单独列出阶段性或可选成本:月度仓储费(按体积与季节,首批小批量时占比通常很低)、入库配置费、广告费、超龄库存费等;标明本次是否计入及理由,避免把“未计入”误当成“不存在”。
  4. 计算四个结果:毛利 = 售价 − 各项每单成本;店铺回款 = 售价 − 平台扣除项(配送费、佣金等);毛利率 = 毛利 ÷ 售价;并核对回款能否覆盖采购与头程等自付现金成本。
  5. 计算保本价:把随售价按比例变动的费用(佣金等)与固定金额费用分开,保本价 = 固定金额成本之和 ÷ (1 − 比例费率之和);用保本价回代验证毛利为零,作为降价、促销与竞价的底线。
  6. 对不同物流方案(空运/海运、不同渠道)各做一版,比较毛利额与毛利率差异;差异大时把物流方案当作决策变量而非常量。
  7. 输出前做敏感性检查:售价下调、汇率变化、退货率上升、广告投入增加时的毛利变动,并标出哪一项最先把利润打穿。

最后做数据充分性检查,并把结论分成 FACT / ESTIMATE / HYPOTHESIS / UNKNOWN。若关键证据不足,状态写 HOLD。

第三方 MCP 数据

仅在自有数据不足且当前任务确实需要外部证据时,读取 references/mcp-data-plan.md,再使用 scripts/mcp_research.py。本 Skill 的外部取数目的:获取同类竞品的公开售价区间,作为测算售价与保本价的对照。

  • 先 doctor,再 search-tools 和 describe;工具名及参数以实时 tools/list 与 inputSchema 为准。
  • Token 只从环境变量读取。不得写入命令参数、URL、Skill、报告、日志或 Git。
  • tools/call 或 Actor 可能计费;先展示 Provider、工具、无密钥业务参数、预计成本与输出位置,核对已有授权覆盖后才加 --allow-cost;该标志不是费用上限。

必须交付的结果

  • 单品成本结构表(每单变动成本与阶段性成本)
  • 毛利、毛利率与店铺回款计算
  • 保本价与回代验证记录
  • 物流方案利润对比
  • 敏感性检查与缺口说明
  • 数据范围、来源、采集时间、样本与限制。
  • 关键假设、待补证据、风险和不可确定项。
  • 若有动作:对象、旧值、新值、预期、停止条件、回退值与审批状态。

方案状态使用 READY FOR REVIEW / DRAFT / HOLD / STOP;如已执行,另行记录实际结果及回读证据。未得到明确批准时,不得声称已修改线上对象。
