At a glance

Calculates China's corporate income tax with automatic preferential-rate detection for small or high-tech enterprises, then checks compliance.

  • Works in 5 steps: Identify Enterprise Type → Get Taxable Income → Calculate Tax → …
  • Calculating a Chinese company's corporate income tax payable
  • SKILL.md covers Overview, Workflow, Error Handling and Gotchas
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Enterprise type gets identified first against four Chinese rate categories, a standard 25 percent rate, a small low-profit enterprise's reduced 5 percent band up to a threshold, a high-tech enterprise's 15 percent rate, and a qualifying non-profit's zero rate, before taxable income is either supplied directly or pulled from the user's financial data. A calculator tool then computes the tax and a compliance checker reviews the result, with numeric computation always done by those tools rather than estimated.

Two gotchas get surfaced automatically: the small low-profit rate only applies below its threshold, with the excess still taxed at 25 percent, and a high-tech enterprise needs a currently valid certification renewed every three years.

When your agent uses it

  • Calculating a Chinese company's corporate income tax payable
  • Checking whether a small or high-tech enterprise rate applies
  • Reviewing a corporate tax calculation for compliance issues

Example prompts

  • “Calculate our corporate income tax as a high-tech enterprise.”
  • “Does our small low-profit rate still apply above this income level?”
  • “Check this tax calculation for compliance issues before filing.”

Requirements

  • tax_calculator, query_user_financial_data, and tax_compliance_checker tools
  • Compatibility (from SKILL.md): Tools: tax_calculator, query_user_financial_data, tax_compliance_checker
  • Pre-approved tools (allowed-tools): Bash, Read

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Identify Enterprise Type
  2. Get Taxable Income
  3. Calculate Tax
  4. Compliance Check
  5. Present Result

What it can do on your machine

Read from SKILL.md and the folder at commit 94b16cd. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    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.

  • Compatibility

    Tools: tax_calculator, query_user_financial_data, tax_compliance_checker

    From compatibility in the SKILL.md frontmatter.

Context cost

Chinese Corporate Income Tax Check loads about 787 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 164 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~787

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 164 words (~787 tokens).
