Returns one page; when `has_more` is true, pass the returned `next_page_token` to continue.
`incomplete_search` true means Drive couldn't search every corpus (results may be partial).

Returns one page; when `has_more` is true, pass the returned `next_page_token` to continue.

A quick, context-safe peek. For the complete data use read_full_sheet (which saves it to a local
file). Pass an explicit a1_range to read exactly that range instead of the preview window.
values: UNFORMATTED | FORMATTED | FORMULA (FORMULA returns cell formulas).

Reads the full tab (item = URL or ID; default first tab) via the Sheets API, writes it to
dest_path (resolved inside the sandbox files dir; a sanitized default name otherwise), and
returns total_rows/total_cols plus the same first-5-rows/cols preview as read_sheet. Use this
instead of read_sheet when you need the complete data without flooding the context.

value_input RAW (default) stores cell text literally; pass 'USER_ENTERED' to interpret typed
values/formulas (a leading '=' becomes a live formula). Overwriting existing non-empty cells
requires confirm=true. dry_run=true returns a predicted before/after (client-side) without
writing; formula cells are shown literally (Google's recalculation is not simulated).

value_input RAW (default) stores cell text literally; 'USER_ENTERED' interprets formulas/typed
values. dry_run=true returns where the rows would land (predicted) without appending.

a1_range like 'Data!A1:C10' or a single cell 'Data!B2' (no tab prefix targets the first
tab; open-ended ranges like 'A:C' are rejected). Each flag is tri-state: true applies it,
false removes it, unset leaves that property as-is. Formatting only — cell values are
untouched. dry_run=true returns the resolved target without writing. (Headings, bullets,
and rich text are Docs concepts: see append_text/create_document with markdown=true.)

dry_run=true returns the values that would be cleared (before) without clearing.

dry_run=true returns the rows that would be deleted without deleting.

Multi-tab docs: by default every tab is read (each prefixed with its title as a heading);
pass a `tab` id, or an `item` URL containing `tab=t.xxxx`, to read only that tab. Returns the
requested chunk (0-based) plus title, the doc's `tabs`, the outline, and paging metadata
(total_chunks, total_chars, has_more). Set max_chars<=0 to get the whole document. Set
include_colors=true to also return `colored_runs` (text spans with an explicit foreground color).

Returns both inline images and positioned (floating/wrapped) images, each emitted at the
paragraph it is anchored to. Multi-tab docs: all tabs by default; pass a `tab` id or an
`item` URL with `tab=t.xxxx`.

markdown=true renders `text` with the same dialect as append_text: headings, bullets,
numbered lists, **bold**, *italic*, <u>underline</u>. (For spreadsheets use
create_spreadsheet.)

markdown=true renders a small dialect instead of storing text verbatim: '#'..'######'
headings, '-'/'*' bullets, '1.' numbered lists (nest with two spaces or a tab per level),
**bold**, *italic*, <u>underline</u>. No escape syntax — text that looks like markup gets
styled; leave markdown unset to write literally. Block content (headings/lists) starts on
its own paragraph rather than merging into the doc's last line. Multi-tab docs: appends to
the given `tab` (id, or an `item` URL with `tab=t.xxxx`), else the first tab. `color` (hex
like '#3366CC') colors the inserted text; leave it unset for plain text. dry_run=true
returns a predicted before/after of the tab's tail without writing.

markdown=true renders the same dialect as append_text (headings, bullets, numbered lists,
**bold**, *italic*, <u>underline</u>); note heading/list styles apply to the whole
paragraphs the insertion touches, so insert block markdown at a paragraph boundary.
Multi-tab docs: pass a `tab` (id, or an `item` URL with `tab=t.xxxx`), else the first tab.
`color` (hex like '#3366CC') colors the inserted text; leave it unset for plain text.
dry_run=true reports what would be inserted and where without writing. (`index` is a Docs
structural offset, so the exact merged text isn't reconstructed client-side.)

Returns one page; when `has_more` is true, pass the returned `next_page_token` to continue.

Google-native files are exported; PDFs are text-extracted. Returns the requested chunk
(0-based) in `content` plus name, mime_type, and paging metadata (total_chunks,
total_chars, has_more) — page through by incrementing chunk. Set max_chars<=0 for the
whole document.

Written to the sandbox files dir when large or dest_path is given (dest_path resolved inside
it); small exports return base64 inline. (Drive's export method has no supportsAllDrives param.)
