Terminal Screenshot (ANSI → PNG)

Renders a CLI command's colored terminal output to PNG so Claude can visually judge contrast, alignment and highlighting instead of reading raw escape codes.

Dev & CodingIntermediate★ 1,323⑂ 212AI score 9/10Last updated: Aug 8, 2026

What it does

  • Captures a command's full-fidelity ANSI output to a .ansi file, then renders it to a PNG for visual inspection.
  • Enforces a strict two-step flow (capture in a real shell, render second) so freeze --execute doesn't silently degrade background blocks, line numbers and header boxes.
  • Lets you pass the real terminal background hex (e.g. Ghostty's #282c34) so dark-theme contrast is judged fairly.
  • Falls back to the bundled scripts/ansi2html.py (stdlib only) + headless Chrome when freeze isn't available.
  • Ships a per-tool capture cheat sheet for delta, git diff, bat, eza, ls, ripgrep and generic commands.

Who it's for

  • Developers tuning delta / bat / starship / eza color themes.
  • Anyone who wants to verify contrast visually rather than guessing from hex values.
  • Users who want Claude Code to review how CLI output actually looks.

Examples

  1. After editing [delta] colors: git --no-pager diff | delta --dark --line-numbers --width=110 > /tmp/diff.ansi, then scripts/render_ansi.sh /tmp/diff.ansi /tmp/diff.png "#282c34" and read the PNG to check add/remove contrast.
  2. bat --color=always --style=numbers app.py > /tmp/x.ansi to confirm a new syntax theme is readable on a dark background.
  3. rg --color=always 'TODO' src > /tmp/x.ansi to see whether match highlighting stands out clearly.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/daymade/claude-code-skills/HEAD/daymade-claude-code/terminal-screenshot/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the daymade-claude-code/terminal-screenshot folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/terminal-screenshot/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git /tmp/ccs && mkdir -p ~/.claude/skills && cp -r /tmp/ccs/daymade-claude-code/terminal-screenshot ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Clone the repo: git clone https://github.com/daymade/claude-code-skills.git /tmp/ccs
  2. Create the skills directory: mkdir -p ~/.claude/skills
  3. Copy the skill in: cp -r /tmp/ccs/daymade-claude-code/terminal-screenshot ~/.claude/skills/
  4. (Recommended) Install the renderer: brew install charmbracelet/tap/freeze — ⚠️ do NOT run plain brew install freeze, that's an unrelated GUI cask. Alternative: go install github.com/charmbracelet/freeze@latest.
  5. If freeze can't be installed, a Chrome install is enough for the bundled fallback renderer.
  6. Make the script executable: chmod +x ~/.claude/skills/terminal-screenshot/scripts/render_ansi.sh
  7. Restart Claude Code and ask something like "screenshot my delta diff colors" or "is this terminal contrast good enough?".
