以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →
English · 简体中文
Left: compiles with zero errors. Right: after five sentences a reader could say out
loud — "remove the rules around the title", "this table is a grid, make it a
booktabs table", "that link runs off the page", "the figure is too wide". Try it
yourself in examples/broken-layout.
A DeepSeek Harness plugin that adds exactly one tool: latexlook.
An agent that only reads .tex source is blind: a document can compile with zero errors and still look wrong. latexlook compiles the document, renders the page as an image, maps any spot on that page back to the exact source line, and diffs what your last edit changed — in a single call.
┌─────────────┐ latexlook ┌──────────────┐
│ agent │ ─────────────► │ pdf → png │
│ (edits .tex)│ │ synctex │
└─────────────┘ ◄───────────── │ pixel diff │
▲ image + line └──────────────┘
└─────────────── verification ───────────┘
Read the case study: a 215-page LaTeX book, read the way a reader reads it — 163 figures, 129 equations, six classes of defect that compile cleanly.
## Why one tool, not three
Rendering, locating, and diffing are the implementation. The agent needs one coherent verb — "look at this page" — the same way a person does. latexlook compiles, renders, resolves, and diffs in a single call, so the loop is:
look → diagnose → edit .tex → look again → confirm the change → report
## Install
Requires Node ≥ 18, a TeX engine (xelatex/lualatex/pdflatex/latexmk or tectonic), synctex, and ghostscript.
This repository is the bundle: package.json declares dsh.bundle.patch, and cordis.patch.yml inserts one row.
bash
git clone https://github.com/fangchenghao/latex-look
Then install it into the current profile (in the Harness, via the plugin manager):
pluginmanager action: installbundle target: /absolute/path/to/latex-look
That adds the row latex-look and registers the latexlook tool. Replacing the sources of an already-installed package needs a Harness restart to load a fresh module generation.
Published on npm as @fffangchenghao/dsh-latex-look, so the same row also installs straight from the registry:
pluginmanager action: installbundle target: @fffangchenghao/dsh-latex-look
### Updating
The plugin checks the registry once a day, in the background, and appends a single line to a tool reply when a newer release exists — no repeated nagging, and an offline machine sees nothing at all. To upgrade, install the same bundle again:
pluginmanager action: installbundle target: @fffangchenghao/dsh-latex-look
On a live profile the upgrade applies immediately; the harness reloads the module generation on the next start, because core.mjs (unlike index.js) is not hot-reloaded.
From a checkout, the check is available directly:
bash
npx latex-look --version
npx latex-look --check-update
### Releasing
Tagging v runs the test suite on Ubuntu with TeX and Ghostscript installed, verifies the tag matches package.json, and publishes to npm. The token comes from the NPMTOKEN repository secret.
### Optional: the knowledge skill
The tool gives the agent eyes. SKILL.md gives it the LaTeX knowledge to act on what it sees — a symptom → cause → fix playbook (a rule you want gone is usually \pagestyle/fancyhdr, not a stray \hline). Copy or symlink it into the skills root:
