Add eyeball plugin: document analysis with inline source screenshots 🤖🤖🤖

[dvelton]

What this adds

Eyeball is a Copilot CLI plugin that generates document analyses as Word files with inline screenshots from the source material. Every factual claim in the analysis includes a highlighted excerpt from the original document, so you can verify each assertion without switching between files or hunting for the right page.

How it works

1. You give Copilot a document (PDF, Word file, or web URL) and ask it to analyze something
2. Eyeball reads the source, writes the analysis, and captures a screenshot of the relevant section from the original document with the cited text highlighted in yellow
3. The output is a Word document on your Desktop with analysis text and source screenshots interleaved

Source types supported

• PDF files (via PyMuPDF)
• Word documents (via Microsoft Word or LibreOffice for conversion)
• Web pages (via Playwright + Chromium)

Plugin contents

• plugins/eyeball/ - plugin.json and README
• skills/eyeball/ - SKILL.md and the eyeball.py tool

Prerequisites for users

Python 3.8+ and the following pip packages: pymupdf, pillow, python-docx, playwright. The SKILL.md includes setup instructions.

• _convert_with_word_windows swallows all exceptions and returns False, but it doesn't reliably call doc.Close() / word.Quit() on failure after Word has been launched. This can leave orphaned WINWORD.EXE processes. Use try/finally to ensure COM objects are closed/quit even when Open/SaveAs fails.

def _convert_with_word_windows(source_path, output_pdf_path):
    """Convert using Microsoft Word on Windows via win32com."""
    try:
        import win32com.client
        word = win32com.client.Dispatch("Word.Application")
        word.Visible = False
        doc = word.Documents.Open(os.path.abspath(source_path))
        doc.SaveAs(os.path.abspath(output_pdf_path), FileFormat=17)  # 17 = PDF
        doc.Close()
        word.Quit()
        return True
    except Exception:
        return False

• render_url_to_pdf manually closes the browser at the end, but if page.goto, page.evaluate, or page.pdf throws, the browser may not be closed cleanly. Wrap browser usage in try/finally (or use Playwright context managers) so Chromium is always closed on errors/timeouts.

    with sync_playwright() as p:
        browser = p.chromium.launch(headless=True)
        page = browser.new_page()
        page.goto(url, wait_until="networkidle", timeout=30000)

        # Clean up navigation/footer elements for cleaner output
        page.evaluate("""
            document.querySelectorAll(
                'header, footer, nav, [data-testid="header"], [data-testid="footer"], '
                + '.site-header, .site-footer, #cookie-banner, .cookie-consent'
            ).forEach(el => el.remove());
        """)

        page.pdf(
            path=output_pdf_path,
            format="Letter",
            print_background=True,
            margin={"top": "0.5in", "bottom": "0.5in",
                    "left": "0.75in", "right": "0.75in"}
        )
        browser.close()

• cmd_screenshot opens the PDF before parsing --anchors. If json.loads(args.anchors) (or later code) raises, pdf_doc.close() is never reached. Consider restructuring to parse/validate inputs first and/or wrap PDF usage in try/finally (or a context manager) to guarantee the file handle is closed on errors.

def cmd_screenshot(args):
    """Generate a single screenshot from a PDF."""
    pdf_doc = fitz.open(os.path.expanduser(args.source))
    anchors = json.loads(args.anchors)
    target_page = args.page
    padding = args.padding or 40

• The build example uses python3 eyeball.py build ... without specifying a path. Unless the instructions require running from the directory containing eyeball.py, this command will fail. Use python3 <path-to>/eyeball.py build ... (or explicitly instruct to run from <plugin_dir>/skills/eyeball/tools).

```bash
python3 eyeball.py build \
  --source "<path-or-url>" \
  --output ~/Desktop/<title>.docx \
  --title "Analysis Title" \
  --subtitle "Source description" \

plugins/eyeball/README.md:37

• The README suggests cloning https://github.com/dvelton/eyeball.git, which doesn't align with how plugins in this repo are meant to be consumed (via the GitHub Copilot plugin marketplace / awesome-copilot). Consider replacing this with the canonical marketplace install instructions, and (if desired) keep the upstream repo link in a separate “Source” section instead of presenting it as the primary install path.

Install via the Copilot CLI plugin system, or clone the repo:

```bash
git clone https://github.com/dvelton/eyeball.git

**skills/eyeball/SKILL.md:123**
* Similarly, the build command example uses `python3 eyeball.py build ...` without a path. For consistency with the earlier “Tool Location” section (and to avoid command failures), use `<path-to>/eyeball.py build ...` or document that the command must be run from the directory containing `eyeball.py`.

Construct a JSON array of sections and call the build command:

python3 eyeball.py build \
  --source "<path-or-url>" \
  --output ~/Desktop/<title>.docx \

plugins/eyeball/README.md:53

• The README references setup.sh / setup.ps1, but those scripts aren’t included in this plugin directory in the current PR. Either add the setup scripts, or remove these steps and rely on the manual pip install ... instructions (plus Playwright browser install) to avoid dead-end setup guidance.

### Install dependencies

**macOS / Linux:**

```bash
cd eyeball
bash setup.sh

Windows (PowerShell):

cd eyeball
.\setup.ps1

@copilot resolve the merge conflicts in this pull request

Resolved the merge conflicts in b14575f. The conflicts were in the auto-generated files (marketplace.json, README.plugins.md, README.skills.md). I merged the staged branch and rebuilt these files with npm run build, which now includes both the new entries from staged (ember plugin, updated README format with install commands) and the eyeball plugin/skill entries.
