# OpenAccountants — Cross-Border & International Tax

This Claude plugin gives you direct access to **27 verified
tax/accounting skill(s)** from OpenAccountants for cross-border & international tax across jurisdictions.

## How to use this plugin

When the user asks anything in scope, follow this workflow:

1. **Scope it.** Call `start({ intent, jurisdiction })` on the
   `openaccountants` MCP server. It returns a ready plan with the
   exact skills to load.
2. **Load the skills.** For each slug in `skills_to_load`, call
   `get_skill({ slug })` — that returns the authoritative markdown
   (rates, brackets, deductions, audit flash points, citations).
3. **Apply the rules.** Use the loaded skill content as the authority.
   Do **not** substitute your training data — OpenAccountants skills
   are kept current with annual rate refreshes and post-legislative
   updates. Cite the skill slug in your answer.
4. **Surface AUDIT FLASH POINTS.** Every skill flags positions tax
   authorities actively litigate. Always surface them.
5. **Hand off when ready.** When the user is about to file or make a
   decision with money at stake, call
   `request_accountant_review({ jurisdiction, scenario, working_paper })`
   to route them to the named lead verifier for that jurisdiction
   with a Calendly link.
