Drive a public GitHub issue (bug report / feature request / docs request) to a landed resolution on a fresh per-ticket branch. Classifies the issue type, then — for the common case of a TeX source + its conversion — builds a red/green TDD reproducer, writes the approach to a scratch TICKET_APPROACH.md, implements to green, and opens the PR. Pairs with canvas-triage, min-repro, perl-port. Invoke for "resolve issue #N", "work on the bug report", "fix this feature request", "handle issue X", "/resolve-issue".
Measure latexml-oxide conversion performance correctly, pick the right build profile, and avoid re-litigating settled optimization questions. Use when benchmarking, comparing against Perl, choosing a profile, diagnosing a slow/OOM conversion, or when tempted to optimize startup/codegen. Invoke for "is this slower?", "benchmark X", "which profile", "optimize startup", "profile this paper", "/perf-check".
Faithfully translate or fix a LaTeXML binding (macro / primitive / constructor / column type / package) from the Perl source to Rust. Use whenever you write or change engine/package code that mirrors Perl LaTeXML — porting a new .pool entry, binding a package, or aligning a definition to Perl semantics. Enforces "read the Perl source first" and the divergence policy. Invoke for "port \foo", "translate this .pool entry", "bind package X", "make Y match Perl", "/perl-port".
Triage a failing/suspicious arXiv paper and decide whether its errors are a GENUINE Rust regression or parity with Perl LaTeXML. Use when investigating a conversion error/fatal, a "Rust-only" candidate from cortex, a sandbox/canvas failure, or any "is this a real bug vs. parity?" question. Pairs with tools/parity_check.sh, triage_failure.sh, first_error.sh and the cortex document/<id> API. Invoke for "triage this paper", "is 1234.5678 a regression", "classify this failure vs Perl", "/canvas-triage".
Reduce a confirmed failing arXiv paper to a minimal, self-contained reproducer (and optionally a regression-test fixture). Use after canvas-triage confirms a GENUINE-RUST-ONLY failure, or whenever you need the smallest .tex that still triggers a specific error/crash. Pairs with tools/bisect_repro.sh and first_error.sh. Invoke for "minimize this paper", "make a reproducer for X", "shrink to a failing case", "/min-repro".
