ByeTex v0.3.0 — Agent in the loop

ByeTex converts LaTeX to Typst for AI agents. v0.3.0 is the "agent in the loop" release:
the MCP server grows from 7 to 11 tools, the visual-fidelity loop becomes one command,
and ByeTex now installs as a Claude Code plugin (plus an install script, crates.io, and Homebrew).

Highlights

11 MCP tools (was 7) — with full CLI parity

  • validate — Stage-0 oracle: compile the input LaTeX with tectonic to tell a broken
    source from a ByeTex bug, before you start repairing.
  • compile / render — typst compile to PDF / per-page PNGs with structured
    errors ({ok, errors, …}) — no more shelling out to typst and scraping stderr.
  • explain — a per-node LaTeX→Typst map: "why did this LaTeX emit this Typst?"
  • convert_fragment now honours its context_hint (math hints wrap the fragment so bare
    math like \frac{1}{2} converts as math, not an unknown text command).

One-command visual-fidelity loop

  • byetex review <paper> renders the converted Typst to per-page PNGs and rasterises the
    original LaTeX render alongside, emitting a grading_packet.json for the
    byetex-visual-grading skill.
  • A two-layer fidelity regression gate: deterministic structural metrics
    (scripts/fidelity_gate.sh) + a vision-graded findings diff (scripts/findings_diff.py).

Reproducible snippet primitives

  • byetex convert -c '\frac12' (or - for stdin) — convert a snippet to stdout, no files.
  • byetex explain -c '…' — the source map for any fragment.

Installs four ways

# Claude Code plugin (skills + MCP server)
claude plugin marketplace add zeyuyang42/ByeTex && claude plugin install byetex@byetex
# Prebuilt binary
curl -fsSL https://raw.githubusercontent.com/zeyuyang42/ByeTex/main/install.sh | sh
# crates.io
cargo install byetex --features mcp
# Homebrew
brew install zeyuyang42/byetex/byetex

Status

  • Compile-rate (the gate): 59/59 ByeTex-attributable arXiv papers compile (100%).
  • Visual fidelity (the driver): 0.821 corpus composite score.
  • CI runs cargo fmt --check + cargo clippy -D warnings + cargo test --workspace (904 tests).

Notes

  • The CLI crate is now published as byetex (so cargo install byetex works); the binary
    name and the crates/byetex-cli directory are unchanged.
  • No conversion-logic changes in this release — it is entirely new agent tooling, packaging,
    and docs, so the 59/59 compile-rate is preserved.
  • Full changelog: CHANGELOG.md.

Binaries in this release

Prebuilt, statically-linked binaries (built locally), verifiable against SHA256SUMS:

Platform Asset
macOS arm64 byetex-v0.3.0-aarch64-apple-darwin.tar.gz
macOS x86_64 byetex-v0.3.0-x86_64-apple-darwin.tar.gz
Linux x86_64 (musl) byetex-v0.3.0-x86_64-unknown-linux-musl.tar.gz
Linux arm64 (musl) byetex-v0.3.0-aarch64-unknown-linux-musl.tar.gz
Windows x86_64 byetex-v0.3.0-x86_64-pc-windows-gnu.zip

The Windows build is the GNU ABI (x86_64-pc-windows-gnu, cross-built via Zig with a static
CRT — imports only Windows system DLLs, no MinGW runtime needed), not MSVC. It runs on Windows
10/11; for a native MSVC build use cargo install byetex or build from source on Windows.
