found in the instruction textThe instruction itself
7 sections, as written by the authorRun the contract review. Read the document, explain what it says, flag anything risky, and produce marked-up redlines for the owner to use in negotiations.
Parse arguments:
FILE_PATH_OR_DOCUSIGN_ENVELOPE_ID— path to a local PDF/docx file, or a DocuSign envelope ID; if omitted, check the most recent envelope awaiting signature in DocuSign
Step 1 — Load the contract
Using the contract-review skill workflow:
- If a file path is given: read the document from Files or Desktop.
- If a DocuSign envelope ID is given: pull the document from DocuSign.
- If neither: check DocuSign for the most recent envelope with status
waiting for signatureand confirm with the owner before proceeding.
Step 2 — Plain-English summary
Produce a 3-paragraph summary:
- What this contract does — the deal in plain terms (who, what, how much, how long)
- Key obligations — what the owner must do and when
- Key rights — what the owner gets and any termination or exit paths
Step 3 — Red-flag list
For each risk, rate severity: 🔴 High / 🟡 Medium / 🟢 Low
Flag at minimum:
- Auto-renewal clauses with short cancellation windows
- Unilateral price change rights
- Broad IP ownership transfers
- Unlimited liability or missing liability cap
- Exclusivity clauses
- Non-compete or non-solicit provisions
- Ambiguous payment or deliverable terms
Format each flag as:
{Severity} {Clause name} — {what it says in plain English} — Suggested redline: {fix}
Step 4 — Marked-up redlines
Generate a list of specific redline suggestions in legal markup format:
§{section}: DELETE "[original language]" / INSERT "[suggested replacement]"
Reason: {one sentence}
Offer to export this as a marked-up docx or PDF to Files or Desktop.
Connector failures
If DocuSign is not connected and no file path was given, ask the owner to upload the contract as a PDF or docx. If DocuSign is connected but the envelope ID is invalid, report the error and ask the owner to check the ID. This command works fully offline with a local file — connectors are optional.
Approval gates
- Never sign, send, or modify the actual DocuSign envelope. Present the review and wait for the owner to act.
- Always caveat: "This is not legal advice. Review with your attorney before signing."
- Never delete or overwrite the original document.
Output
Present the plain-English summary, red-flag list, and redline suggestions. Ask the owner whether to export a marked-up copy and where to save it.

Presentation creation, editing, and analysis. When Claude needs to work with presentations (.pptx files) for: (1) Creating new presentations, (2) Modifying or editing content, (3) Working with layouts, (4) Adding comments or speaker notes, or any other presentation tasks
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
