Open a project and run the safety gate: pull, verify every \usepackage resolves locally, then baseline-compile each root. Required before any write.

Map a document's structure with line numbers — sections, figures, labels, includes. Use before reading; far cheaper than the whole file.

Read a file, line-numbered. lines='150-190' reads a range; omit for all. Prefer a range guided by outline.

Regex-search the project, returning file:line: match.

List .tex files, marking which are roots.

Compile the root owning path and return a digest. Errors block a push; warnings do not. verbose=True shows every error and warning.

One page of the compiled PDF as an image, for layout only — float placement, overlap, figure sizing. Expensive: try compile() warnings first, and use read() for anything about the text itself.

Replace an exact snippet, then compile and push. old must appear exactly once. Reverts if the result does not compile.

Create or overwrite a file, then compile and push. For new documents and whole-file rewrites; prefer edit() for changes to an existing document.

Copy a local image or binary into the project, then push. Compiles only the roots that actually reference it — an unreferenced file cannot break a build.
