| description | This snippet should be used when reading, organizing, and naming screenshots with date prefixes. |
When this skill is in your context, you should base your answer from the newest screenshots.
Analyze what screenshots you should read implicitly by getting the current time via date. Or explicitly, if the user says HEAD~{n}, which is the top n screenshots, or N, which is the nth screenshot, or [1, 3, 5] which is the 1, 3rd, and 5th screenshot, and other similar notation. Where the screenshots are ordered by time from newest to oldest.
When you need to analyze screenshots or images provided by the user:
~/DesktopRead tool: ~/Desktop/Screenshot_*.png
CRITICAL: After reading any screenshot, you MUST:
YYYY-MM-DD~/Desktop/claude_screenshots/YYYY-MM-DD-{descriptive-name}.{extension}
Examples:
2025-10-13-login-page-error.png2025-10-13-dashboard-layout.png2025-10-13-api-response-json.jpg# After reading a screenshot from Desktop:
# 1. Determine descriptive name based on content
# 2. Create directory if needed
mkdir -p ~/Desktop/claude_screenshots
# 3. Move and rename with date prefix
mv ~/Desktop/Screenshot_2023-10-13_at_10.30.45.png \
~/Desktop/claude_screenshots/2025-10-13-user-profile-page.png
CRITICAL: macOS screenshot filenames contain spaces (e.g., Screenshot 2025-10-13 at 11.07.11 PM.png)
Best practice - Use glob pattern with variable in loop:
# ✅ CORRECT - Glob pattern handles spaces automatically
cd /Users/wz/Desktop && for f in Screenshot*11.07.11*.png; do
mv "$f" claude_screenshots/2025-10-13-descriptive-name.png
done
Why this works:
$f is quoted to preserve spacesAlternative methods (less reliable):
# ⚠️ Escaping spaces - error-prone with multiple spaces
mv Screenshot\ 2025-10-13\ at\ 11.07.11\ PM.png destination.png
# ⚠️ Quotes - can fail with nested quotes or special chars
mv "Screenshot 2025-10-13 at 11.07.11 PM.png" destination.png
Lesson learned: When moving files with complex filenames (spaces, special chars), prefer glob patterns with loops over manual escaping.
Problem: Read tool fails on complex filenames (parentheses, Spanish characters, multiple periods)
Solution: Move → Rename → Read
mkdir -p ~/Desktop/claude_screenshots
cd ~/Desktop
i=1
for f in "Captura de pantalla 2025-10-23 a la(s) 8.20"*.png; do
[ -f "$f" ] && mv "$f" "claude_screenshots/2025-10-23-temp-$i.png" && i=$((i+1))
done
# Read from ~/Desktop/claude_screenshots/2025-10-23-temp-*.png
# Then rename descriptively after analysis
Use when: Glob finds files but Read fails, Spanish macOS, parentheses, multiple periods
When taking screenshots with Playwright or other automation tools:
ALWAYS save directly to the organized location:
// Playwright example
await page.screenshot({
path: `~/Desktop/claude_screenshots/${date}-${descriptiveName}.png`,
});
Python example:
from datetime import datetime
date = datetime.now().strftime('%Y-%m-%d')
screenshot_path = f'~/Desktop/claude_screenshots/{date}-{descriptive_name}.png'
driver.save_screenshot(screenshot_path)
