GitHub lawyers moved to the terminal: their colleague built an AI-review skill in Copilot CLI
The Eyeball skill puts a contract screenshot with a highlighted quote beneath every AI claim and installs with one command.

When the cost of a mistake is high, trust decides everything. Dan, Senior Corporate Counsel at GitHub, built his own skill with GitHub Copilot CLI: it inserts screenshots of source documents directly into the text so the AI's analysis can be checked. Dan's aptly named tool, Eyeball, helps the legal team unpack complex contract clauses and act confidently on the AI's conclusions. Now every GitHub lawyer works in the terminal to make everyday tasks easier. ▶️

Dan, GitHub’s director of legal, built himself a working tool right in the terminal.
His Eyeball skill analyzes a contract and puts the result into a Word file, where every AI claim is followed by a screenshot of the original page with the quote highlighted in yellow. It accepts .docx, PDF, RTF, and public web addresses.
The lawyer built software for himself without developers, and now the company’s entire legal department works through GitHub Copilot CLI.
Installs with one command. `gh skills install github/awesome-copilot eyeball`. You need GitHub CLI version 2.90.0 or later; the awesome-copilot directory contains more than 400 skills. Before its first run, Eyeball asks for dependencies: `pip3 install pymupdf pillow python-docx playwright`, then `python3 -m playwright install chromium`. Microsoft Word or LibreOffice must be installed for .docx files, otherwise Word documents will not open.
The invocation looks like a normal phrase: `use eyeball on ~/Desktop/vendor-agreement.docx -- analyze the indemnification provisions`. The finished document lands on the desktop. The CLI itself installs via `npm install -g @github/copilot` and requires Node.js 22 or later.
This is not the first case. Ngandu Kasuku, another GitHub lawyer, built the terms-ai tool on the same CLI. He used to copy prompts by hand; now he maintains a repository with instructions and drafts and estimates that review and drafting time has been cut roughly in half (GitHub blog, 04.08.2026).
There is no separate charge for Eyeball: the CLI is included in all GitHub Copilot plans, with the cheapest, Pro, at $10 per month with 1500 credits (GitHub pricing, 20.09.2026).
Next, these tools will be built not by developers but by the departments that need them.
