Seer

Overview

Grab a precise screenshot of a visible app window and attach it for visual iteration.

Quick start

  1. Ensure the target app is running and Screen Recording + Accessibility are enabled for your terminal.
  2. Run the script:
    • bash scripts/capture_app_window.sh (defaults to frontmost app, output /tmp/seer/app-window-shot-YYYYMMDD-HHMMSS-<pid>-<rand>.png)
    • bash scripts/capture_app_window.sh /path/to/out.png "Promptlight" (custom output + process name)
  3. Attach the image with view_image.

Usage

  • bash scripts/capture_app_window.sh --help
  • bash scripts/capture_app_window.sh [out_path] [process_name]
    • out_path default /tmp/seer/app-window-shot-YYYYMMDD-HHMMSS-<pid>-<rand>.png
    • process_name default frontmost app
    • set SEER_TMP_DIR to change default output dir

Workflow

  1. Capture
    • scripts/capture_app_window.sh
    • If it fails, rerun with explicit process name or verify permissions.
  2. Inspect
    • Use view_image to load the output.
  3. Iterate
    • Repeat after UI changes or window repositioning.

  • capture_app_window.sh: grabs window bounds via System Events and runs screencapture -x -R.
