Reading & Editing Documents

Three CLIs ship with this plugin under ${CLAUDE_PLUGIN_ROOT}/bin/. They are also symlinked onto PATH as readoc, readir, and editdoc, so you can usually call them by bare name.

The standard Read/Edit/Write tools cannot parse or modify .docx/.xlsx/.pdf. Use these instead. The readers never truncate content — spreadsheet cells, pages, and tables are emitted in full.

readoc — read specific files

readoc file.docx                 # read a Word document
readoc file.xlsx                 # read an Excel spreadsheet
readoc file.pdf                  # read a PDF
readoc file1.docx file2.xlsx     # read several; each gets a header box
readoc --no-comments file.docx   # omit comments (included by default)

# Search inside one file (structure-aware context — see "Search modes" below)
readoc search file.docx "deadline"                       # default: line context
readoc search file.docx "deadline" --context-paragraphs 1
readoc search report.pdf "risk"    --context-chars 120
readoc search budget.xlsx "Q3"                           # cell-coordinate aware

Each file is preceded by an unambiguous header box (path (Type, size)), so concatenated output is never confusing. Headings, tables, and sheets are preserved; long cells overflow their column rather than being cut.

Comments

Document comments are included by default, appended per file in a trailing --- Comments --- block with the author and an anchor — Word comments (author: text), Excel cell comments ([Sheet!A1] author: text), and PDF annotations / sticky notes ([Page N] author: text). Pass --no-comments to suppress them (body text is unaffected). The block is only emitted when a file actually has comments.

readir — explore / read / search a folder

# Tree — explore structure
readir tree path/to/folder                    # file tree with sizes
readir tree path/to/folder --summary          # + extension/size summary
readir tree path/to/folder --max-depth 1      # depth: 1 = top level only, 2 = one level deep
readir tree path/to/folder --filter docx,pdf  # only certain extensions

# Read — concatenate all readable files (same header-box convention as readoc)
readir read path/to/folder
readir read path/to/folder --filter md,docx   # only specific types
readir read path/to/folder --exclude pdf      # skip certain types
readir read path/to/folder --max-size 2000    # KB ceiling; files over it are
                                              # SKIPPED (and listed), not truncated
readir read path/to/folder --max-depth 1
readir read path/to/folder --no-skip-report
readir read path/to/folder --no-comments      # omit comments (included by default)

# Search — grep across all docs (incl. docx/xlsx/pdf)
readir search path/to/folder "query"
readir search path/to/folder "query" --context 5            # lines of context (default 2)
readir search path/to/folder "query" --context-paragraphs 1 # whole paragraphs of context
readir search path/to/folder "query" --context-chars 120    # character window of context
readir search path/to/folder "query" --context-rows 3       # rows of context (spreadsheets)
readir search path/to/folder "query" --filter docx
readir search path/to/folder "query" --no-comments          # don't search comment text

Search modes

Both readir search and readoc search are structure-aware, doing what a plain grep cannot:

• Prose (.docx, .pdf, .md, .txt, …) — choose one context unit (mutually exclusive, default --context lines):
  • --context N — N lines around each match (the original behaviour).
  • --context-paragraphs N — the matching paragraph ± N whole paragraphs (units marked ¶); respects real paragraph boundaries.
  • --context-chars N — a ±N character window around each match, merging overlapping windows. The matched term is wrapped in »…«.
• Spreadsheets (.xlsx) — always searched cell by cell. Each hit reports Sheet!Cell plus its column header (row 1) and row header (column A), e.g. Budget!C7 [col "Amount" / row "Q3"] <value>, followed by a window of the matching rows ± --context-rows (default 2). Cell comments are searched too.

You can still pipe to ordinary tools for line-oriented work (readoc file.docx | grep -A3 deadline, … | head, find ./docs -name '*.docx') — the built-in modes add the structure-aware context that piping can't.

Comments are extracted by default for readir read (and are searchable by both search commands), in the same --- Comments --- form as readoc. Use --no-comments to opt out.

Supported formats: .md .txt .csv .docx .xlsx .pdf .json .yaml .yml.

The one deliberate limit

readir read defaults to skipping files larger than 500 KB to avoid dumping huge files unintentionally. Skipped files are listed in the skip report (never silently dropped, never truncated). Raise the ceiling with --max-size <KB> when you genuinely need a large file.

editdoc — edit .docx / .xlsx files

editdoc is to binary Office documents what the built-in Edit tool is to text files. It takes the target file as an argv and reads a JSON edit spec from stdin — a single object, or an array of objects applied as one atomic batch. The edit type is chosen by which keys the object carries:

# 1) Word — exact in-paragraph replace (mirrors the Edit tool)
echo '{"old_string": "due Monday", "new_string": "due Friday"}' | editdoc report.docx
echo '{"old_string": "TODO", "new_string": "Done", "replace_all": true}' | editdoc report.docx

# 2) Word — paragraph / range replace (structural)
echo '{"start_contains": "Quarterly results", "new_text": "Replaced paragraph."}' | editdoc report.docx
echo '{"start_contains": "First old para", "end_contains": "last old para", "new_text": "New A\nNew B"}' | editdoc report.docx
echo '{"start_contains": "Stale section", "new_text": ""}' | editdoc report.docx   # "" deletes

# 3) Excel — set a cell
echo '{"sheet": "Budget", "cell": "B2", "value": "1250"}' | editdoc book.xlsx

# Batch: an array is applied all-or-nothing
echo '[{"old_string":"a","new_string":"b"},{"sheet":"S","cell":"A1","value":1}]' | editdoc f.docx

# Force editing an xlsx that has charts/macros/etc (see Limitations)
echo '{"sheet":"Budget","cell":"B2","value":42}' | editdoc book.xlsx --force

docx edit types

• In-paragraph replace — {"old_string", "new_string", "replace_all"?}. old_string is matched exactly (whitespace included) against each paragraph's visible text, across body paragraphs and table cells. It must be unique in the document; if it appears more than once you get a loud error — add surrounding context to disambiguate, or set "replace_all": true. A match cannot span a paragraph break (no newline in old_string).
• Paragraph / range replace — {"start_contains", "end_contains"?, "new_text"}. start_contains (and optional end_contains) each uniquely identify a paragraph; the inclusive block between them is replaced by new_text, split on \n into one-or-more paragraphs that inherit the original's style. Empty new_text deletes the block. A range must stay within one container (the body, or a single table cell).

xlsx edit type and value coercion

• Cell set — {"sheet", "cell", "value"}. The sheet must exist and the cell must be a valid reference (B2). A string value becomes a number only when it round-trips exactly: "1250"→1250, "-42"→-42, "3.5"→3.5, but codes that would be corrupted stay text — leading zeros ("00501"), underscores ("1_000"), scientific notation ("1e3"), and non-finite values ("nan", "inf"). Pass a JSON number (42, 3.5) to force numeric storage; a JSON boolean stores a boolean; JSON null clears the cell.

Why a naive find/replace fails on Word (and how editdoc handles it)

Word stores a visible sentence as a chain of formatting runs — "the report is due" might be ["the ", "report", " is due"] with the middle run bold. A literal search on the raw XML usually misses it. editdoc reconstructs each paragraph's text, matches there, and rewrites the runs so the replacement inherits the first matched run's formatting while untouched text keeps its own. After each edit it prints a confirmation line plus the affected paragraph rendered as Markdown (**bold**, *italic*, heading #) so you can verify the formatting landed as intended.

Multi-paragraph rewrites

In-paragraph replace can't cross a paragraph break. To rewrite several consecutive paragraphs at once, use a single range replace: anchor the first paragraph with start_contains, the last with end_contains, and pass the full new text in new_text (newline-separated for multiple paragraphs). This turns, say, a five-paragraph block into three paragraphs in one atomic edit — no per-paragraph delete chain.

Safety

Every edit is validated before the file is written; if any edit in a batch fails, nothing is written (the file stays byte-identical) and editdoc exits non-zero with a specific error. Saves go through a temp file + atomic replace, so a crash never corrupts the original. Read the result back with readoc to confirm.

Limitations

• Hyperlinks / fields / footnote refs: a paragraph whose text isn't carried entirely by ordinary runs (it contains a hyperlink, field, or footnote reference) is refused rather than rewritten — editing it would scramble the non-run content. Delete the whole paragraph (range op with empty new_text) or adjust the document instead. Such a paragraph can still be matched/deleted, just not rewritten in place.
• Nested tables: only top-level table cells are reached; text inside a table nested within a cell is not found.
• xlsx fidelity: openpyxl rewrites the whole workbook on save and can drop features it doesn't model. editdoc scans the workbook and refuses when it detects charts, pivot tables, drawings/images, or macros, naming what would be lost — pass --force (or --allow-lossy) to edit anyway and accept the loss. Plain data workbooks edit with no flag. (Detection is by file contents, so it can't see every lossy feature; --force skips the check entirely.)
• No .pdf editing (no clean text reflow).

Requirements

uv must be on PATH, it's the only prerequisite. Each CLI declares its Python dependencies inline via PEP 723 and runs through uv run --script, so uv installs them into a cached environment automatically on first use: readoc/readir use python-docx, openpyxl, and pymupdf (for .docx, .xlsx, and .pdf); editdoc uses python-docx and openpyxl.
