Screenshot Capture

Follow these save-location rules every time:

1. If the user specifies a path, save there.
2. If the user asks for a screenshot without a path, save to the OS default screenshot location.
3. If Codex needs a screenshot for its own inspection, save to the temp directory.

Tool priority

• Prefer tool-specific screenshot capabilities when available (for example: a Figma MCP/skill for Figma files, or Playwright/agent-browser tools for browsers and Electron apps).
• Use this skill when explicitly asked, for whole-system desktop captures, or when a tool-specific capture cannot get what you need.
• Otherwise, treat this skill as the default for desktop apps without a better-integrated capture tool.

macOS permission preflight (reduce repeated prompts)

On macOS, run the preflight helper once before window/app capture. It checks Screen Recording permission, explains why it is needed, and requests it in one place.

The helpers route Swift's module cache to $TMPDIR/codex-swift-module-cache to avoid extra sandbox module-cache prompts.

bash <path-to-skill>/scripts/ensure_macos_permissions.sh

To avoid multiple sandbox approval prompts, combine preflight + capture in one command when possible:

bash <path-to-skill>/scripts/ensure_macos_permissions.sh && \
python3 <path-to-skill>/scripts/take_screenshot.py --app "Codex"

For Codex inspection runs, keep the output in temp:

bash <path-to-skill>/scripts/ensure_macos_permissions.sh && \
python3 <path-to-skill>/scripts/take_screenshot.py --app "<App>" --mode temp

Use the bundled scripts to avoid re-deriving OS-specific commands.

macOS and Linux (Python helper)

Run the helper from the repo root:

python3 <path-to-skill>/scripts/take_screenshot.py

Common patterns:

• Default location (user asked for "a screenshot"):

python3 <path-to-skill>/scripts/take_screenshot.py

• Temp location (Codex visual check):
