By name: copy-to-clipboard
description: Pipe the response's prose to the macOS clipboard via pbcopy so the user can paste it directly. Use when the user says "copy to clipboard", "/copy", "pbcopy this", "put it on my clipboard", or otherwise asks for paste-ready output. macOS only.
What to copy
The final user-facing prose for this turn — what the user would otherwise read in the chat. Skip tool output, diffs, status updates, and code fences that exist only to display content in chat. If the requested output is a snippet, copy the snippet's contents without the surrounding fences.
How
One Bash call. Single-quoted heredoc with a random 6-char sentinel:
pbcopy <<'CLIP_a93b2f'
…content…
CLIP_a93b2f
The single quotes disable expansion, so $, backticks, backslashes, and newlines pass through literally — the quoting hazards the previous file-based approach worried about don't apply. Pick a fresh sentinel each call; collision with content is the only failure mode and is negligible for normal prose.
Fallback (only if content might literally contain your sentinel — e.g. you're copying a doc about heredocs): Write to /tmp/clip.txt, then pbcopy < /tmp/clip.txt. No rm — /tmp cleans itself and the chained command can trip the harness into backgrounding.
For a short single-line string, printf '%s' '<text>' | pbcopy is fine.
After
Acknowledge in one short line (e.g., Copied.) and stop — do not reprint the content; the user already has it. If command -v pbcopy finds nothing, say so and skip the copy. Don't try to install a clipboard tool.
