adeu 0.5.5

Automated DOCX Redlining Engine

Adeu OSS: DOCX Redlining Engine

Adeu allows AI Agents and LLMs to safely "Track Changes" in Microsoft Word documents.

Most LLMs output raw text or Markdown. Legal and compliance professionals need w:ins (insertions) and w:del (deletions) to review changes natively in Word.

Adeu solves this by treating DOCX as a "Virtual DOM". It presents a clean, readable text representation to the AI, and then reconciles the AI's edits back into the original XML structure without breaking formatting, numbering, or images.

🚀 New in v0.5.0

• Comments & Threads: Full support for reading and replying to Word comments using CriticMarkup syntax ({==Target==}{>>Comment<<}).
• Negotiation Actions: Agents can now ACCEPT, REJECT, or REPLY to specific changes and comments.
• Safety: Enhanced protection against corrupting nested revisions or structural boilerplate.

Ways to Use Adeu

1. As an MCP Server

Connect Adeu directly to your agentic workspace. This allows AI Agent to read contracts, propose redlines, and answer comments natively.

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "adeu": {
      "command": "uvx",
      "args": ["adeu", "adeu-server"]
    }
  }
}

What the Agent sees: The agent receives a text view of the document where comments and changes are clearly marked:

The Vendor shall be liable for {==indirect damages==}{>>[Counsel] We request this be removed.<<}...

Available MCP Tools

Tool	Description
read_docx	Reads a DOCX file. supports clean_view=True to simulate "Accept All Changes" before reading.
diff_docx_files	Compares two DOCX files and returns a text-based Unified Diff, ignoring formatting noise.
apply_structured_edits	The Core Engine. Applies a list of "Search & Replace" edits, generating native Track Changes (w:ins/w:del).
manage_review_actions	Review workflow. Allows the Agent to ACCEPT, REJECT, or REPLY to specific changes or comments by ID.
accept_all_changes	Creates a clean version of the document by accepting all revisions and removing comments.

2. For Python Developers ("Vibe Coding")

Adeu handles the heavy lifting of XML manipulation so you can focus on the logic.

from adeu import RedlineEngine, DocumentEdit
from io import BytesIO

# 1. Load your contract
with open("NDA.docx", "rb") as f:
    stream = BytesIO(f.read())

# 2. Define the change (e.g., from an LLM response)
# Adeu uses "Search & Replace" logic with fuzzy matching
edit = DocumentEdit(
    target_text="State of New York",
    new_text="State of Delaware",
    comment="Standardizing governing law."
)

# 3. Apply the Redline
engine = RedlineEngine(stream, author="AI Associate")
engine.apply_edits([edit])

# 4. Save
with open("NDA_Redlined.docx", "wb") as f:
    f.write(engine.save_to_stream().getvalue())

3. The CLI

Quickly extract text or apply patches from your terminal.

# Compare two docs and get a summary
adeu diff v1.docx v2.docx

# Apply a structured edit list (JSON) to a doc
adeu apply agreement.docx edits.json --author "Reviewer Bot"

Why Adeu?

• Native Redlines: Generates real Microsoft Word Track Changes. You can "Accept" or "Reject" them in Word.
• Format Safe: Preserves complex numbering, headers, footers, and images. It only touches the text you change.
• Token Efficient: Converts heavy XML into lightweight Markdown for the LLM context window.
• Intelligent Mapping: Handles the messy internal XML of Word documents (e.g., when "Contract" is split into ["Con", "tract"] by spellcheck).
