Copy generated text content to clipboard. An agent skill from umputun/cc-thingz.

  • Works in 4 steps: Identify the text content to copy (from… → Write to timestamped temp file → Copy to clipboard and remove temp file → …
  • User asks to copy this
  • SKILL.md covers Activation Triggers, Workflow and Notes
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Txt Copy is an agent skill from umputun/cc-thingz. Copy generated text content to clipboard. Use when user asks to "copy this", "copy to clipboard", "save to clipboard", or after creating emails, messages, letters, or other text content that needs to be shared.

Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: various things for claude code. The licence is MIT.

When your agent uses it

  • User asks to copy this
  • Copy to clipboard
  • Save to clipboard
  • After creating emails

Example prompts

  • “copy this”
  • “copy to clipboard”
  • “save to clipboard”
  • “/txt-copy”

Requirements

  • Pre-approved tools (allowed-tools): Bash

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify the text content to copy (from recent generation or user-specified)
  2. Write to timestamped temp file
  3. Copy to clipboard and remove temp file
  4. Confirm to user: "Copied to clipboard (N characters)"

What it can do on your machine

Read from SKILL.md and the folder at commit 99e1c8d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Txt Copy loads about 365 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 119 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~365

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Copy Text to Clipboard

Copy generated text content to clipboard via a timestamped temp file.

Activation Triggers

  • "copy this", "copy to clipboard", "save to clipboard"
  • "copy the email", "copy the message", "copy the letter"
  • After generating text content when user indicates they want to use it
  • "I need to paste this", "put it in clipboard"

Workflow

  1. Identify the text content to copy (from recent generation or user-specified)

  2. Write to timestamped temp file:

bash
tmpfile="/tmp/claude-txt-copy-$(date +%s).txt"
cat > "$tmpfile" << 'EOF'
<content here>
EOF
  1. Copy to clipboard and remove temp file:
bash
if [[ "$OSTYPE" == "darwin"* ]]; then
    pbcopy < "$tmpfile"
elif command -v xclip &> /dev/null; then
    xclip -selection clipboard < "$tmpfile"
elif command -v xsel &> /dev/null; then
    xsel --clipboard --input < "$tmpfile"
else
    echo "No clipboard tool found" >&2
fi
rm -f "$tmpfile"
  1. Confirm to user: "Copied to clipboard (N characters)"

Notes

  • Use cat with heredoc and single-quoted EOF to preserve exact content
  • Temp file uses timestamp to avoid collisions across invocations
  • Temp file is removed after clipboard copy
