LaTeX Compile + QA

Triggers & routing

• Trigger: latex compile, build PDF, LaTeX errors, missing refs, 编译PDF, 引用错误.
• Use when: 已有 latex/main.tex（通常来自 latex-scaffold），需要确认可编译并输出失败原因报告。

Compile the LaTeX project and produce a PDF (when the toolchain is available), plus a short build report.

This step is deterministic; if compilation fails, record actionable diagnostics rather than guessing.

Inputs

• latex/main.tex
• citations/ref.bib

Outputs

• latex/main.pdf (if compilation succeeds)
• output/LATEX_BUILD_REPORT.md (recommended)

Workflow

1. Run a LaTeX build (e.g., latexmk) if available.
2. Fix missing packages, missing bib entries, and unresolved references.
3. Record remaining issues in a build report.

Quality checklist

• latex/main.pdf exists only when compilation succeeds; failed builds must remove stale PDFs and explain the failure in output/LATEX_BUILD_REPORT.md.
• For arxiv-survey-latex deliverables: latex/main.pdf is >= 8 pages and has no undefined citations/references (strict gate).

Script

Quick Start

• uv run python .codex/skills/latex-compile-qa/scripts/run.py --help
• uv run python .codex/skills/latex-compile-qa/scripts/run.py --workspace <workspace>

All Options

• See --help (inputs/outputs are taken from the unit runner when used via pipeline)

Examples

• Compile + produce report:
  • uv run python .codex/skills/latex-compile-qa/scripts/run.py --workspace <workspace>

Notes

• Uses latexmk -xelatex -bibtex when available.
• Always writes output/LATEX_BUILD_REPORT.md (success or failure).
• Report includes page count + warning summary when available.

Troubleshooting

Common Issues

Issue: latexmk not found

Symptom:

• Build report says “latexmk not found in PATH”.

Causes:

• LaTeX toolchain is not installed.

Solutions:

• Install a TeX distribution that includes latexmk.
• If you can’t install tools, still use latex-scaffold to generate latex/main.tex and compile elsewhere.

Issue: Build fails with bib/ref errors

Symptom:

• Report shows missing citations/refs or BibTeX errors.

Causes:

• citations/ref.bib missing/miswired, or draft contains invalid cite keys.

Solutions:

• Ensure latex/main.tex points to ../citations/ref.bib (or the correct relative path).
• Ensure all citation keys exist in citations/ref.bib.

Recovery Checklist

• Read output/LATEX_BUILD_REPORT.md tail for the first actionable error.
• Confirm latex/main.tex exists and bibliography path is correct.
