List the historical UNIX documents available on this server, with metadata such as title, authors, source URL, page count, and a short description.

Return metadata for one document plus a page-by-page overview (first line of each page), useful as a table of contents before reading specific pages.

Search the ingested UNIX documentation. Returns ranked page-level matches with a snippet around the first hit. Optionally restrict to a single document by doc_id.

Read raw text of one page or a contiguous range of pages from a document. Use get_document_info first to find the right pages.

List the 4.2BSD manual pages, optionally restricted to a section (1=commands, 2=syscalls, 3=libc, 4=devices, 5=formats, 6=games, 7=documents, 8=admin, l=local, n=new, o=obsolete).

Search the 4.2BSD manual pages. Returns ranked matches with a snippet around the first hit. Restrict with section (2=syscalls, 3=libc, 4=devices, 5=formats).

Read the full text of one 4.2BSD manual page by name and optional section (e.g. name="read", section="2"). If the name is ambiguous across sections, give the section.

Search the 4.2BSD kernel and userland C source. Returns matching lines in the style of grep (path:line: code). Optionally filter by a path substring such as "netinet" or "libc/gen".

Read a source file from the 4.2BSD tree by path (e.g. "sys/sys/sysent.c" or "src/lib/libc/gen/read.c"). Optionally restrict to a line range. At most 1500 lines are returned.

Locate a function, struct, macro, typedef, or variable across the 4.2BSD source. Definitions are listed first, then declarations and references, each as path:line: code.

List the 4.2BSD system call table (number, name, and any notes). Optionally filter by name substring.

Look up a 4.2BSD system call by number or name (e.g. "2" or "fork"). Returns its number, name, and any notes.

Search across all corpora at once: prose documentation, manual pages, and source code. Results are grouped by kind and labeled.
