Key Enhancements

🚀 Enhanced Search & Replace

• Regex support for complex pattern matching

• Case-insensitive search options

• Whole word matching

• Advanced formatting application to replaced text

• Group substitutions for regex patterns

# Regex date format conversion
enhanced_search_and_replace("doc.docx", 
    find_text=r"(\d{4})-(\d{2})-(\d{2})", 
    replace_text=r"$2/$3/$1", 
    use_regex=True)

# Case-insensitive formatting
enhanced_search_and_replace("doc.docx", 
    find_text="important", 
    replace_text="CRITICAL",
    match_case=False, 
    apply_formatting=True, 
    bold=True, color="red")

📝 Unified Text Extraction

# Extract full document with formatting
get_text("doc.docx", scope="all", include_formatting=True)

# Search within document
get_text("doc.docx", scope="search", search_term="methodology", match_case=False)

# Extract specific paragraph
get_text("doc.docx", scope="paragraph", paragraph_index=5)

📑 Flexible Section Management

# Extract all sections with formatting
get_sections("doc.docx", mode="overview", include_formatting=True)

# Get specific section content
get_sections("doc.docx", mode="content", section_title="Results")

🔒 Advanced Protection Management

# Password protection
manage_protection("doc.docx", action="protect", protection_type="password", password="secure123")

# Restricted editing with editable sections (metadata + optional encryption depending on environment)
manage_protection("doc.docx", action="protect", protection_type="restricted",
                 password="review123", editable_sections=["Introduction", "Conclusion"])

Usage Examples

Academic Writing Workflow

# Create research paper structure
create_document("research_paper.docx", title="Machine Learning Analysis", author="Dr. Smith")

# Add structured content
add_text_content("research_paper.docx", "Abstract", content_type="heading", level=1)
add_text_content("research_paper.docx", "This study examines...", content_type="paragraph", 
                style="Normal", position="end")

# Footnotes/endnotes are disabled (python-docx limitation). Insert notes manually in Word if needed.

# Format academic terms
format_research_paper_terms("research_paper.docx")

# Extract structure for review
sections = get_sections("research_paper.docx", mode="overview", max_level=2)

Document Review Workflow

# Extract review elements
comments = manage_comments("draft.docx", action="list")  # list-only (legacy in-text markers)
changes = extract_track_changes("draft.docx")

# Generate comprehensive review summary
summary = generate_review_summary("draft.docx")

# Manage track changes selectively
manage_track_changes("draft.docx", action="accept", change_type="insertions")
manage_track_changes("draft.docx", action="reject", change_type="deletions", author="Reviewer1")

Document Security Workflow

# Apply comprehensive protection
manage_protection("confidential.docx", action="protect", 
                 protection_type="password", password="secure123")

# Add digital signature
add_digital_signature("contract.docx", signer_name="John Doe", 
                     reason="Document approval")

verification = verify_document("contract.docx")

Tool Reference

Consolidated Tools

get_text(filename, scope, **options)

Unified text extraction with multiple modes:

• scope: "all" | "paragraph" | "search" | "range"

• include_formatting: Extract formatting information

• search_term: Text to search for (when scope="search")

• paragraph_index: Specific paragraph (when scope="paragraph")

manage_track_changes(filename, action, **filters)

• action: "accept" | "reject" | "extract"

• change_type: "all" | "insertions" | "deletions" | "formatting"

• author: Filter by specific author

• date_range: Filter by date range

add_note(...)

Footnotes/endnotes are disabled in this server (python-docx limitation). Insert notes manually in Word.

add_text_content(filename, text, content_type, **options)

Unified content creation:

• content_type: "paragraph" | "heading"

• level: Heading level (1-6)

• style: Apply document style

• position: "beginning" | "end" | "before" | "after"

get_sections(filename, mode, **options)

Advanced section extraction:

• mode: "overview" | "content"

• section_title: Optional section to target

• max_level: Maximum heading level

• output_format: "text" | "json"

Safety Guardrails

enhanced_search_and_replace and get_text(scope="search") apply configurable limits to avoid runaway searches, oversized responses, and memory pressure:

• EW_MAX_MATCHES_PER_CALL (default 1000)

• EW_MAX_SEARCH_OUTPUT_CHARS (default 200000)

• EW_MAX_REGEX_PATTERN_CHARS (default 5000)

• EW_MAX_REGEX_SCAN_CHARS (default 2000000)

• EW_MAX_DOC_BYTES_PER_OPERATION (default 50000000)

• EW_MAX_UNDO_BYTES_TOTAL (default 200000000)

• EW_LONG_SESSION_OP_LIMIT (default 2000)

• EW_REGEX_TIMEOUT_MS (default 0; if set and timeout runtime is unavailable, operation is refused explicitly)

When limits are hit, tools return explicit guardrail codes/messages, including:

• LIMIT_EXCEEDED

• REGEX_COMPLEXITY_BLOCKED

• DOC_TOO_LARGE

• UNDO_BUDGET_EXCEEDED

• SESSION_CONSISTENCY_WARNING

Mutation-heavy operations use fail-before-mutate semantics for preflight guardrail failures.

Session Consistency Contract

• Disk path is authoritative for document state.

• document_id is a routing alias to file paths.

• In-memory session metadata is advisory and may lag; tools read from file paths each call.

Error Handling

All tools provide comprehensive error handling:

# Typical error responses
{
  "status": "error",
  "message": "Document not found: nonexistent.docx",
  "error_type": "FileNotFoundError",
  "suggestions": ["Check file path", "Ensure file exists"]
}
