Description
Amazon FBA profit calculator. Input product price, COGS, dimensions, weight, and ad spend — get true net profit, margin, ROI, and break-even ACoS. Triggers:...
Usage Guidance
This skill appears to be a legitimate FBA profit calculator, but there is a notable mismatch: the runtime instructions show a CLI (`fba ...`) and permit running Bash, yet the skill bundle includes no code and no install instructions. Before installing or enabling this skill you should: 1) Verify the linked GitHub repo (https://github.com/mguozhen/amazon-fba-calculator) to confirm whether a separate CLI exists and how to install it from a trusted source; 2) Be aware that allowed-tools: Bash grants the agent the ability to run shell commands — confirm what commands it will run or restrict the Bash tool if you don't want remote shell execution; 3) If you expect a purely conversational calculator (no external binary), ask the author to remove CLI examples or provide an inline implementation in SKILL.md; 4) If you plan to install a third-party CLI, prefer installing from official releases (GitHub releases, package manager) and audit the binary/source code before granting the agent permission to execute it. If you can't confirm the origin of the CLI or the expected commands, consider treating the skill as untrusted.
Capability Assessment
Purpose & Capability
Name, description, and SKILL.md content all describe an FBA profit calculator and include formulas, fee tables, metrics, and rules consistent with that purpose.
Instruction Scope
The SKILL.md lists CLI commands (e.g., `fba calc`, `fba fees`, `fba save`) and sets allowed-tools: Bash, implying it expects to run a local CLI. However the skill provides no code, no install, and no declared required binaries — it's unclear how those commands are satisfied. allowed-tools: Bash also means the agent could run arbitrary shell commands at runtime; while the instructions themselves remain focused on calculations, this tool permission combined with the missing CLI is an unexplained risk.
Install Mechanism
There is no install spec and no code files (instruction-only). That is low-risk from supply-chain perspective, but it creates a functional mismatch because the SKILL.md documents a CLI without declaring or installing it. The author may have intended to document a separate CLI repository (homepage provided) but did not link an install step.
Credentials
The skill declares no required environment variables, no credentials, and no config paths. This aligns with a local calculator that doesn't need external secrets.
Persistence & Privilege
No elevated privileges or always:true present. The skill is user-invokable and allows model invocation (normal). It doesn't request persistent system-level presence.
