Why a skill, not a naked LLM
Cited to statute
Every threshold, rate, and rule references the section, regulation, or revenue procedure it comes from. Easy to verify, easy to defend.
Verified by accountants
Each skill is reviewed section-by-section by a licensed practitioner in the relevant jurisdiction. No vibes. No hallucinated numbers.
Year-dated
Skills declare the tax year they apply to and the date they were last verified. The agent surfaces both, so the next reader knows what they're looking at.
Three steps
Clone the skill
Pick the skill that matches your jurisdiction and situation (e.g. us-sole-prop-bookkeeping). Drop it into your agent's context — works with Claude Code, Cursor, Codex, Continue, and anything else that reads markdown.
Run the computation
Feed the agent your bank statements, invoices, or bookkeeping export. The skill produces a working paper with the computation, assumptions, citations, and a self-check checklist.
Get a licensed accountant to sign off
Share the working paper with a verified CPA, EA, or Chartered Accountant in your jurisdiction. They check the numbers and flag anything that needs fixing before you file.
