Prefer vault_delete_span when removing without replacement.\n\nParameters:\n- end_anchor is searched at or after the start line, so the span can never run backward; it must be unique among those lines. If both match the same line, only that one line is replaced. A span that includes a code block's opening fence can't end at a plain closing fence (```): every fragment of the closing fence also appears in the opening fence, so the end anchor is ambiguous, and first_match: true would end the span at the opening fence; to replace such a block, use vault_replace_in_note.\n- content: empty lines at its start and end join the empty lines around the replaced lines, and each joined gap keeps the larger of the two counts (only at the end of the note, the count above drops by one). So content can widen a gap but not narrow it: a trailing newline leaves at least one empty line after the new block unless the block ends the note. Content made only of empty lines joins both sides into one gap. Empty lines inside content are written as given, and no other empty line in the note changes. A line holding only spaces or tabs counts as text, not as an empty line.\n- first_match applies to both anchors independently.\n\nErrors:\n- \"note not found\" — verify path with vault_list_notes\n- \"path must end in …\" — add the .md extension\n- \"start anchor not found\" / \"end anchor not found\" — no line contains the fragment (for end_anchor, none at or after the start line); verify with vault_read_note\n- \"ambiguous start anchor …\" / \"ambiguous end anchor …\" — the anchor matches multiple lines; use a longer fragment or set first_match: true\n- \"absolute path blocked\" / \"path traversal blocked\" / \"hidden path blocked\" — use a vault-relative path with no hidden (dot-prefixed) file or folder in it\n- \"concurrent write in progress\" — another write to this note is in flight; re-read the note and retry\n- \"content contains a control character\" — content includes a non-printable control byte; remove it before writing\n- \"ENAMETOOLONG: …\" — the path, or a name in it, is longer than the filesystem allows; check the path. If the quoted name ends in \".tmp\", the note exists but its name is too long to save; rename it at least 41 bytes shorter\n- \"EACCES: …\" or another filesystem error code — the note's file can't be read or written (permissions, a full or read-only disk); ask the vault's owner to fix it\n- \"properties block …\" — the note's properties block can't be read, or a rewrite would lose it; the error says how to repair it\n- \"the note would open with a properties block …\" — the edit would leave --- lines at the top of a note with no properties, around text that can't be kept as properties; the error says how to avoid it\n\nObsidian syntax: content is Obsidian Flavored Markdown (no escaping applied). Watch for: #word = tag, [[ = wikilink, %% = comment block.\n\nReturns: Confirmation message \"Replaced <N> lines with <M> lines in <path>\" — N counts the lines the span covered, M the line breaks in content plus one.",

Replaces text in place; does not move content across sections.\nTo delete a large multi-line block, prefer vault_delete_span (short anchors instead of full old_text).

No regex.\n- new_text: non-empty new_text replaces the match exactly. A deletion (new_text=\"\") that leaves an empty line where the match was joins the empty lines above and below it into one gap that keeps the larger of the two counts (only at the end of the note, the count above drops by one); where matches empty their lines, the gap keeps at least one empty line unless it ends the note, so include the line break in old_text to remove the line. Any other deletion, such as text inside a line or a line break that joins two lines, is written exactly as asked. Empty lines outside the joined gaps never change.

Animated GIFs are reduced to their first frame when recompressed.\n- Canvas (.canvas): a readable markdown outline per JSON Canvas 1.0 — groups (by visual containment), node content in reading order, and a connections list with edge labels.\n- PDFs (.pdf): structured text with document metadata — title, page count, heading hierarchy (from font sizes relative to the body text), code blocks and inline code (from monospace fonts), page separators, and a deduplicated links footer. Richer than flat text extraction: headings, code, and hyperlinks that flat extraction loses are preserved.\n- Text formats (.svg/.json/.txt/.csv/.xml/.log/.yaml/.yml/.base): the file content verbatim as text. .svg is returned as its XML source; .base as its YAML source.\n\nraw: true switches a canvas or PDF to its other form:\n- Canvas: the exact JSON source (geometry, ids, colors — full fidelity) instead of the outline.\n- PDF: each page rendered and returned as an image block instead of extracted text, showing layout, diagrams, tables, and formatting that text extraction cannot preserve. Image-only and scanned PDFs work in raw mode. Only the first 5 pages are rendered; the text read (without raw) covers every page.\n\nLine paging: start_line and limit page any text result — text formats, canvas outlines and raw JSON, PDF-extracted text — as a 1-based line window, preceded by a metadata line stating the window, the total line count, and where to continue (\"data.csv — lines 51–100 of 400 (continue with start_line: 101)\"). The text output cap (100 KiB) applies to each window, so one very long line can still overflow it; paging never gets around the file-size cap. Paged windows come back with \\n line endings and no trailing newline; a read without paging inputs stays byte-exact.\n\nWhen to use: whenever a note references a file you need to actually see or read — an embedded diagram, a linked canvas, data file, or PDF. Find the files a note links to (with byte sizes) via vault_get_outgoing_links; browse a folder's files via vault_list_files. vault_search also indexes canvas, PDF, and text-format content, but not images or other files. For .md notes use vault_read_note — this tool rejects them.

+      "description": "Read a non-markdown vault file in its most useful form per type — the read-side companion to vault_read_note for everything that isn't a note.\n\nExample: vault_read_file({ path: \"attachments/diagram.png\" }) — the image itself, shrunk when too large\nExample: vault_read_file({ path: \"Boards/Roadmap.canvas\" }) — a readable outline of the canvas\nExample: vault_read_file({ path: \"exports/data.json\" }) — the file content as text\nExample: vault_read_file({ path: \"exports/big.csv\", limit: 500 }) — the first 500 lines, preceded by a metadata line stating the window and total line count\nExample: vault_read_file({ path: \"papers/research.pdf\" }) — structured text with title, headings, and links\n\nWhat each file type returns:\n- Images (.png/.jpg/.jpeg/.gif/.webp): the image as a viewable image block — downscaled and recompressed server-side when it exceeds the image output budget (MAX_IMAGE_OUTPUT_BYTES, 49152 bytes) or 1568 pixels on its longer side, delivered untouched otherwise — plus a text line stating the path, delivered format/dimensions/bytes, and the original dimensions when shrunk. Animated GIFs are reduced to their first frame when recompressed.\n- Canvas (.canvas): a readable markdown outline per JSON Canvas 1.0 — groups (by visual containment), node content in reading order, and a connections list with edge labels.\n- PDFs (.pdf): structured text with document metadata — title, page count, heading hierarchy (from font sizes relative to the body text), code blocks and inline code (from monospace fonts), page separators, and a deduplicated links footer. Richer than flat text extraction: headings, code, and hyperlinks that flat extraction loses are preserved.\n- Text formats (.svg/.json/.txt/.csv/.xml/.log/.yaml/.yml/.base): the file content verbatim as text. .svg is returned as its XML source; .base as its YAML source.\n\nraw: true switches a canvas or PDF to its other form:\n- Canvas: the exact JSON source (geometry, ids, colors — full fidelity) instead of the outline.\n- PDF: each page rendered and returned as an image block instead of extracted text, showing layout, diagrams, tables, and formatting that text extraction cannot preserve. Image-only and scanned PDFs work in raw mode. Only the first 5 pages are rendered; the text read (without raw) covers every page.\n\nLine paging: start_line and limit page any text result — text formats, canvas outlines and raw JSON, PDF-extracted text — as a 1-based line window, preceded by a metadata line stating the window, the total line count, and where to continue (\"data.csv — lines 51–100 of 400 (continue with start_line: 101)\"). The text output cap (100 KiB) applies to each window, so one very long line can still overflow it; paging never gets around the file-size cap. Paged windows come back with \\n line endings and no trailing newline; a read without paging inputs stays byte-exact.\n\nWhen to use: whenever a note references a file you need to actually see or read — an embedded diagram, a linked canvas, data file, or PDF. Find the files a note links to (with byte sizes) via vault_get_outgoing_links; browse a folder's files via vault_list_files. vault_search also indexes canvas, PDF, and text-format content, but not images or other files. For .md notes use vault_read_note — this tool rejects them. To check a large file's line count before reading it whole, request start_line: 1 with limit: 1 — one line plus the total.\n\nErrors:\n- \"not a file\" — the path ends in .md; read notes with vault_read_note\n- \"file not found\" / \"ENAMETOOLONG: …\" — nothing exists at that path, or the path (or a name in it) is longer than the filesystem allows; discover valid paths via vault_list_files\n- \"absolute path blocked\" / \"path traversal blocked\" / \"hidden path blocked\" — use a vault-relative path with no hidden (dot-prefixed) file or folder in it (hidden files are not readable, matching Obsidian)\n- \"file too large\" — the file exceeds the file-size cap (MAX_FILE_BYTES, default 50 MiB)\n- \"text output too large\" — a text file, canvas, or PDF renders past the text output cap; page it with start_line and limit, or reduce limit when a single window overflows\n- \"start line past the end\" — start_line exceeds the file's line count; the error states the total, so retry with a smaller start_line\n- \"line range is not available\" (start_line or limit on an image, or on a PDF read with raw: true) / \"raw source is not available for images\" (raw on an image) — drop that input; paging applies only to text results, and an image always comes back as its image block\n- \"not valid UTF-8\" — the file's bytes aren't UTF-8 text; returning them would silently corrupt the content\n- \"invalid .canvas JSON\" — the canvas file is empty or not valid JSON, so no outline can be built; set raw: true to read its source as text\n- \"PDF has no extractable text\" — the PDF contains no text (scanned or image-only); the error states the page count. Set raw: true to render pages as images instead\n- \"PDF is password-protected\" — the PDF needs a password, which this tool cannot supply; read an unprotected copy instead\n- \"PDF is damaged or not a PDF\" / \"could not decode image\" — the PDF does not parse, or the image is empty, damaged, not an image despite its extension, or over about 268 million pixels; replace or re-export the file\n- \"PDF page rendering failed\" — raw: true was set and the PDF opened, but no page could be rendered; read it without raw: true to get its text instead. If that read also finds no text, this tool can't read the PDF\n- \"image cannot be fitted\" — the image could not be compressed under the image output budget\n- \"EACCES: …\" or another filesystem error code — the file can't be read (permissions, a symbolic link loop); ask the vault's owner to fix it\n- unsupported types (audio, archives, …) return an error naming the readable types plus the file's existence and size\n\nReturns: for images, an image content block plus a one-line metadata text block; for PDFs with raw: true, a metadata text block followed by alternating image and text blocks (one pair per page); for every other supported type, a single text content block — preceded by a window-metadata text block when start_line or limit was given.",

Animated GIFs are reduced to their first frame when recompressed.\n- Canvas (.canvas): a readable markdown outline per JSON Canvas 1.0 — groups (by visual containment), node content in reading order, and a connections list with edge labels.\n- PDFs (.pdf): structured text with document metadata — title, page count, heading hierarchy (from font sizes relative to the body text), code blocks and inline code (from monospace fonts), page separators, and a deduplicated links footer. Richer than flat text extraction: headings, code, and hyperlinks that flat extraction loses are preserved.\n- Text formats (.svg/.json/.txt/.csv/.xml/.log/.yaml/.yml/.base): the file content verbatim as text. .svg is returned as its XML source; .base as its YAML source.\n\nraw: true switches a canvas or PDF to its other form:\n- Canvas: the exact JSON source (geometry, ids, colors — full fidelity) instead of the outline.\n- PDF: each page rendered and returned as an image block instead of extracted text, showing layout, diagrams, tables, and formatting that text extraction cannot preserve. Image-only and scanned PDFs work in raw mode. Only the first 5 pages are rendered; the text read (without raw) covers every page.\n\nLine paging: start_line and limit page any text result — text formats, canvas outlines and raw JSON, PDF-extracted text — as a 1-based line window, preceded by a metadata line stating the window, the total line count, and where to continue (\"data.csv — lines 51–100 of 400 (continue with start_line: 101)\"). The text output cap (100 KiB) applies to each window, so one very long line can still overflow it; paging never gets around the file-size cap. Paged windows come back with \\n line endings and no trailing newline; a read without paging inputs stays byte-exact.\n\nWhen to use: whenever a note references a file you need to actually see or read — an embedded diagram, a linked canvas, data file, or PDF. Find the files a note links to (with byte sizes) via vault_get_outgoing_links; browse a folder's files via vault_list_files. vault_search also indexes canvas, PDF, and text-format content, but not images or other files. For .md notes use vault_read_note — this tool rejects them. To check a large file's line count before reading it whole, request start_line: 1 with limit: 1 — one line plus the total.\n\nErrors:\n- \"not a file\" — the path ends in .md; read notes with vault_read_note\n- \"file not found\" — nothing exists at that path; discover valid paths via vault_list_files\n- \"absolute path blocked\" / \"path traversal blocked\" / \"hidden path blocked\" — use a vault-relative path with no hidden (dot-prefixed) file or folder in it (hidden files are not readable, matching Obsidian)\n- \"file too large\" — the file exceeds the file-size cap (MAX_FILE_BYTES, default 50 MiB)\n- \"text output too large\" — a text file, canvas, or PDF renders past the text output cap; page it with start_line and limit, or reduce limit when a single window overflows\n- \"start line past the end\" — start_line exceeds the file's line count; the error states the total, so retry with a smaller start_line\n- \"line range is not available\" (start_line or limit on an image, or on a PDF read with raw: true) / \"raw source is not available for images\" (raw on an image) — drop that input; paging applies only to text results, and an image always comes back as its image block\n- \"not valid UTF-8\" — the file's bytes aren't UTF-8 text; returning them would silently corrupt the content\n- \"invalid .canvas JSON\" — the canvas file is empty or not valid JSON, so no outline can be built; set raw: true to read its source as text\n- \"PDF has no extractable text\" — the PDF contains no text (scanned or image-only); the error states the page count. Set raw: true to render pages as images instead\n- \"PDF page rendering failed\" — raw: true was set but no pages could be rendered; the PDF may be corrupt\n- \"image cannot be fitted\" — the image could not be compressed under the image output budget\n- an image that cannot be decoded (corrupt, empty, or not an image despite its extension) fails with the decoder's message, e.g. \"Input buffer contains unsupported image format\"; replace or re-export the file\n- unsupported types (audio, archives, …) return an error naming the readable types plus the file's existence and size\n\nReturns: for images, an image content block plus a one-line metadata text block; for PDFs with raw: true, a metadata text block followed by alternating image and text blocks (one pair per page); for every other supported type, a single text content block — preceded by a window-metadata text block when start_line or limit was given.",

Each anchor locates a full line — the entire line is selected, not just the matching substring. Case-sensitive matching. Properties are preserved; YAML formatting may be normalized to block style on first edit. Operates on the body only.\n\nExample: vault_delete_span({ path: \"Tracker.md\", start_anchor: \"| 2024-03-02 | Acme\" }) — deletes the one table row whose line contains that fragment.\nExample: vault_delete_span({ path: \"Notes/Plan.md\", start_anchor: \"> [!warning] Stale\", end_anchor: \"remove after launch\" }) — deletes from the start anchor line through the end anchor line.\n\nWhen to use: Removing a block you have already read — a table row, callout, or run of list items — where reproducing it exactly as old_text would be error-prone. Pick a short, unique fragment of the first line for start_anchor and, for a multi-line block, the last line for end_anchor.\nPrefer vault_replace_in_note for small in-place edits (this tool only deletes). To replace a block, use vault_replace_span (one atomic step).\n\nParameters:\n- start_anchor + end_anchor define a line range, not a text range (never cuts mid-line). Omit end_anchor for a single-line delete. The empty lines above and below the removed lines join into one gap that keeps the larger of the two counts (only at the end of the note, the count above drops by one); no other empty line in the note changes. A line holding only spaces or tabs counts as text, not as an empty line.\n- end_anchor is searched at or after the start line, so the span can never run backward; it must be unique among those lines. If both match the same line, only that one line is deleted.\n- first_match applies to both anchors independently — when an anchor matches multiple lines, takes the first instead of erroring.\n\nErrors:\n- \"note not found\" — verify path with vault_list_notes\n- \"path must end in …\" — add the .md extension\n- \"start anchor not found\" / \"end anchor not found\" — no line contains the fragment (for end_anchor, none at or after the start line); verify with vault_read_note\n- \"ambiguous start anchor …\" / \"ambiguous end anchor …\" — the anchor matches multiple lines; use a longer fragment or set first_match: true\n- \"absolute path blocked\" / \"path traversal blocked\" / \"hidden path blocked\" — use a vault-relative path with no hidden (dot-prefixed) file or folder in it\n- \"concurrent write in progress\" — another write to this note is in flight; re-read the note and retry\n- \"properties block …\" — the note's properties block can't be read, or a rewrite would lose it; the error says how to repair it\n- \"the note would open with a properties block …\" — the edit would leave --- lines at the top of a note with no properties, around text that can't be kept as properties; the error says how to avoid it\n\nReturns: Confirmation with the number of lines the span covered and a preview of them, cut at 80 characters.",

Animated GIFs are reduced to their first frame when recompressed.\n- Canvas (.canvas): a readable markdown outline per JSON Canvas 1.0 — groups (by visual containment), node content in reading order, and a connections list with edge labels.\n- PDFs (.pdf): structured text with document metadata — title, page count, heading hierarchy (from font sizes relative to the body text), code blocks and inline code (from monospace fonts), page separators, and a deduplicated links footer. Richer than flat text extraction: headings, code, and hyperlinks that flat extraction loses are preserved.\n- Text formats (.svg/.json/.txt/.csv/.xml/.log/.yaml/.yml/.base): the file content verbatim as text. .svg is returned as its XML source; .base as its YAML source.\n\nraw: true switches a canvas or PDF to its other form:\n- Canvas: the exact JSON source (geometry, ids, colors — full fidelity) instead of the outline.\n- PDF: each page rendered and returned as an image block instead of extracted text, showing layout, diagrams, tables, and formatting that text extraction cannot preserve.

The text output cap (100 KiB) applies to each window, so one very long line can still overflow it; paging never gets around the file-size cap. Paged windows come back with \\n line endings and no trailing newline; a read without paging inputs stays byte-exact.\n\nWhen to use: whenever a note references a file you need to actually see or read — an embedded diagram, a linked canvas, data file, or PDF. Find the files a note links to (with byte sizes) via vault_get_outgoing_links; browse a folder's files via vault_list_files. vault_search also indexes canvas, PDF, and text-format content, but not images or other files. For .md notes use vault_read_note — this tool rejects them. To check a large file's line count before reading it whole, request start_line: 1 with limit: 1 — one line plus the total.\n\nErrors:\n- \"not a file\" — the path ends in .md; read notes with vault_read_note\n- \"file not found\" — nothing exists at that path; discover valid paths via vault_list_files\n- \"absolute path blocked\" / \"path traversal blocked\" / \"hidden path blocked\" — use a vault-relative path with no hidden (dot-prefixed) file or folder in it (hidden files are not readable, matching Obsidian)\n- \"file too large\" — the file exceeds the file-size cap (MAX_FILE_BYTES, default 50 MiB)\n- \"text output too large\" — a text file, canvas, or PDF renders past the text output cap; page it with start_line and limit, or reduce limit when a single window overflows\n- \"start line past the end\" — start_line exceeds the file's line count; the error states the total, so retry with a smaller start_line\n- \"line range is not available\" (start_line or limit on an image, or on a PDF read with raw: true) / \"raw source is not available for images\" (raw on an image) — drop that input; paging applies only to text results, and an image always comes back as its image block\n- \"not valid UTF-8\" — the file's bytes aren't UTF-8 text; returning them would silently corrupt the content\n- \"invalid .canvas JSON\" — the canvas file is empty or not valid JSON, so no outline can be built; set raw: true to read its source as text\n- \"PDF has no extractable text\" — the PDF contains no text (scanned or image-only); the error states the page count.

Animated GIFs are reduced to their first frame when recompressed.\n- Canvas (.canvas): a readable markdown outline per JSON Canvas 1.0 — groups (by visual containment), node content in reading order, and a connections list with edge labels.\n- PDFs (.pdf): structured text with document metadata — title, page count, heading hierarchy (from font sizes relative to the body text), code blocks and inline code (from monospace fonts), page separators, and a deduplicated links footer. Richer than flat text extraction: headings, code, and hyperlinks that flat extraction loses are preserved.\n- Text formats (.svg/.json/.txt/.csv/.xml/.log/.yaml/.yml/.base): the file content verbatim as text. .svg is returned as its XML source; .base as its YAML source.\n\nraw: true switches a canvas or PDF to its other form:\n- Canvas: the exact JSON source (geometry, ids, colors — full fidelity) instead of the outline.\n- PDF: each page rendered and returned as an image block instead of extracted text, showing layout, diagrams, tables, and formatting that text extraction cannot preserve.

Set raw: true to render pages as images instead\n- \"PDF is password-protected\" — the PDF needs a password, which this tool cannot supply; read an unprotected copy instead\n- \"PDF is damaged or not a PDF\" / \"could not decode image\" — the PDF does not parse, or the image is empty, damaged, not an image despite its extension, or over about 268 million pixels; replace or re-export the file\n- \"PDF page rendering failed\" — raw: true was set and the PDF opened, but no page could be rendered; read it without raw: true to get its text instead. If that read also finds no text, this tool can't read the PDF\n- \"image cannot be fitted\" — the image could not be compressed under the image output budget\n- \"EACCES: …\" or another filesystem error code — the file can't be read (permissions, a symbolic link loop); ask the vault's owner to fix it\n- unsupported types (audio, archives, …) return an error naming the readable types plus the file's existence and size\n\nReturns: for images, an image content block plus a one-line metadata text block; for PDFs with raw: true, a metadata text block followed by alternating image and text blocks (one pair per page); for every other supported type, a single text content block — preceded by a window-metadata text block when start_line or limit was given.",
