What it does

Invoice Generator is an agent skill from luzhenqian/ai-coding-lab. 从 Excel 时间表或手动输入生成专业发票。当用户提到生成发票、创建账单、invoice、billing、开发票、时间表转发票、账单生成时使用此技能。

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/brand-config.json` and `scripts/parse_timesheet.py`).

It sits in Documents & Office, covering Forms and invoices and Excel spreadsheets. It works with Microsoft Excel. The repository describes itself as: 适合所有人的 AI 编程、AI 应用开发的实战教程——从 Vibe Coding 到 Agent、RAG,循序渐进,边学边做。

When your agent uses it

  • Tasks that involve Forms and invoices
  • Tasks that involve Excel spreadsheets

Example prompts

  • “/invoice-generator”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit a33cbe8. 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.

    Shell commands in SKILL.md call:

    • python

    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

Invoice Generator loads about 955 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 24 tokens; SKILL.md has 119 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~955
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 119 words (~955 tokens).
