Suggestion for the tools list: GitHub - karanb192/itr-wala: File your Indian income tax return (ITR) from your terminal. Deterministic tax engine, both regimes, AY 2026-27. Claude Code / Codex / Gemini skill. · GitHub - open source (MIT) agent skill that prepares ITR with a deterministic tax engine. The LLM only reads documents and interviews you; every calculation runs in tested Python, both regimes, AY 2026-27. Disclosure: I built it. My account can’t edit the wiki yet, so leaving the line here for anyone who can.

Any objections to including this maybe raised within 3 days!

Local model supported?

[Karan_Bansal]

Yes. It is an agent skill and would work with any AI agent like Codex, Kiro, etc.
It will also work with any local model with any harness.
