Create a new Overleaf project and return its id. The project is immediately visible and editable in the Overleaf web UI by a human.

List every file in the project with its size. Reflects edits made by humans in the web UI, not just files written through this server.

Read one file from the project. Call this before rewriting a file a human may have touched, so your edit is based on current content.

Create or overwrite a file. Writes are merged into the live document as an operational transform, so a human with the project open sees the change immediately and their cursor is preserved. NOTE: this replaces the whole file — read_file first if the content may have changed.

Delete a file from the project.

Compile the project and return structured diagnostics. Returns a verdict, plus errors with file/line and suggested fixes. Does NOT return the PDF itself (it would flood your context) — use get_pdf if you need the bytes. Check verdict first: if it says BLOCKED, the server environment is at fault and retrying will not help.

Compile and save the PDF to a local file, returning the path. Use when you need the artifact itself; for fixing errors use compile instead.

Fetch the raw LaTeX log from the last compile. Use only when compile's structured diagnostics are not enough — the raw log is long.
