How contributing works
Write the skill
A skill is a markdown file with frontmatter, IRC/state statute citations, computation rules, and self-checks. Download the template and follow the structure of the existing CA skills as a reference.
Submit it
Upload your skill through the platform or submit a PR on GitHub. It appears immediately on the site as “unverified.”
Accountants verify
Licensed accountants review each section of your skill. When every section is approved, the skill goes green. Your name stays on it as the author.
Users install and run it
Once verified, the skill is part of the platform. Users install it, run it in their AI agent, and submit their outputs for review — just like the CA skills.
Quality tiers & promotion path
Every skill has a quality tier. Your submission starts as Q3 (AI-drafted). As the skill improves, it can be promoted all the way to Q1 (Battle-tested).
Tested against real data. Practitioner signed off.
Deep research against tax authority sources. Not yet tested on real data.
Needs real client data + practitioner sign-off to reach Q1.
AI-generated with structure and citations. Not independently verified.
Needs deep research against tax authority websites to reach Q2.
Placeholder with correct metadata. No computation logic yet.
Needs content to be written to reach Q3.
Q4 → Q3: Fill in the computation logic and citations.
Q3 → Q2: Automated — AI restructures and cross-references against tax authority websites.
Q2 → Q1: Requires humans — tested against real client data, practitioner signs off.
Separately, licensed accountants verify each section. A skill can be Q2 + Fully Verified — high-quality research and every section reviewed by a CPA/EA.
