Token cost

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.

Security

Grade A, and why

tax-law-research 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 9d 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.

Tax Law Research Skill

Overview

Searches the web for current tax laws, regulations, rates, and policy changes using Tavily web search. Results are sourced from government and authoritative legal databases.

Workflow

Step 1: Understand the Query

Identify what the user needs:

  • Tax type: Corporate income tax, VAT, personal income tax, stamp duty, etc.
  • Jurisdiction: National (China), provincial, or specific city
  • Time relevance: Current rates, recent changes, upcoming deadlines
  • Specific topic: Deduction rules, exemption policies, filing requirements

If the query is vague, ask clarifying questions before searching.

Step 2: Construct Search Queries

Build targeted Chinese-language search queries. Examples:

Search 1: "企业所得税 税率 2025 最新规定"
Search 2: "增值税 优惠政策 2025 国家税务总局"
Search 3: "个人所得税 专项附加扣除 最新标准"
Search 4: "{specific_tax_topic} 法规 2025"

Use the search_web MCP tool (or the fallback script) with each query.

Step 3: Review and Synthesize Results

Review the search results:

  • Prioritize results from .gov.cn domains (authoritative)
  • Note the publication date of each result
  • Cross-reference multiple sources for consistency
  • Always check the effective date — tax laws change frequently

Step 4: Present Findings

Format as a clear, structured response:

## Tax Law Research Results

**Topic**: [Tax topic] | **Search Date**: [today]

### Current Status
- Rate/Requirement: [current value]
- Effective from: [date]
- Source: [URL]

### Recent Changes
- [Change description] — effective [date]
- Impact: [what this means]

### Key Deadlines
- [Deadline item]: [date]

### Caveats
- This information is from web search and may not reflect the most current changes
- Always verify with a qualified tax professional for binding advice

Step 5: Handle Special Cases

  • Conflicting information: Note the discrepancy and recommend verifying with the local tax bureau
  • No results found: Broaden the search, try English keywords, or suggest the user contact tax authorities directly
  • Outdated information: If search results are older than 6 months, flag them as potentially outdated

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.
