What the tool actually does

Produces stable change IDs, line ranges and exact before/after text.
Links all matching playbook rules and their highest risk flag; unmatched edits stay unclassified.
Validates excerpt identity, rule links, risk labels and complete change coverage.

Bring: Reviewed UTF-8 text/Markdown, body DOCX or best-effort text PDF, plus a JSON keyword playbook.
Get: A deterministic line diff and a review-only brief citing original change IDs. No signing or submission.
Without a model: Document text extraction, line diff and mechanical keyword triage; optional agent narrative.

Small, invented example—not a customer result

Synthetic NDA change C-a5e96e0d4615
Before: liability limited to fees paid
After: liability unlimited for all claims
Playbook: LIAB / high (keyword triage)
Registered-mail addition: unclassified, not “safe”

Illustrative excerpt from the shipped synthetic fixtures. A successful example is not an accuracy benchmark.

Where RedlineBrief stops

Not legal advice. A qualified reviewer must inspect the originals. Keyword risk is not legal analysis. DOCX headers/footnotes/comments/tracked revisions are not fully supported. PDF requires optional pdftotext, may lose layout and has no OCR.

Tested on Linux/Python with small synthetic inputs. Customer workloads, Windows/macOS, agent auto-install/discovery and every host version are untested.

In the download

Actual Skill recipe and deterministic Python engine/validator
English README, input fixtures, reference outputs and executable unit tests
Personal/internal commercial-use license; client outputs are allowed, source-pack redistribution is not

Python 3.10+ is required. SheetAudit also needs openpyxl. Text-PDF extraction in RedlineBrief optionally needs Poppler pdftotext. Models and third-party runtimes are not included. These are source tools, not one-click desktop installers.
