Where exactly does Jev show up in this coding agent?

The README documents no Jev surface at all. Repo evidence is narrower: a Rust crate pi-natives carrying jev.rs and pack-jev tooling, plus tokenizer vocabularies recovered from jev-1.13.0 usage probes. Treat the typed-check and routing claims as repo-level, not as described features.

Will 60+ providers and 31 tools really make my edits land more often?

Those numbers come from the project's own table, credited to harness changes rather than model improvements. Grok Code Fast 1 goes from 6.7% to 68.3% and MiniMax from 1x to 2.1x on pass rate at the same weights and prompt. The README links a write-up, not a reproducible benchmark.

Does it just rewrite files, or respect my IDE's view of the project?

The IDE's view. LSP is wired into every write, so a rename goes through workspace/willRenameFiles and re-exports, barrel files and aliased imports update before the file moves. It also drives real debuggers, attaching lldb, dlv or debugpy instead of scattering print statements.

Is this an original project or a reskin of someone else's?

A fork, stated at the top of the README. It is built on Pi by Mario Zechner and adds features on top. Pull requests are temporarily open to everyone as a trial, and the README warns that the previous vouch requirement may return.

How do I install oh-my-pi?

On macOS or Linux run curl -fsSL https://omp.sh/install | sh, use brew install can1357/tap/omp, bun install -g @oh-my-pi/pi-coding-agent, or nix run github:can1357/oh-my-pi; Windows has a PowerShell installer. It needs bun 1.3.14 or newer.

What tokenizer data does pi-natives ship for Jev?

The pi-natives data README recovered the jev_base and jev_whole token vocabularies from jev-1.13.0 usage probes in September 2026, and the Rust crate pi-natives includes jev.rs and pack-jev tooling alongside Claude tokenizer data.

Is oh-my-pi an original agent or a fork of something?

It is built by Stencil Labs as a fork of Mario Zechner's Pi and adds its own surface: 60+ providers, 31 built-in tools, 14 LSP ops, 28 debug-adapter ops and roughly 80k lines of Rust core, all under MIT.
