Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

txt-copy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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:

tmpfile="/tmp/claude-txt-copy-$(date +%s).txt"
cat > "$tmpfile" << 'EOF'
<content here>
EOF
  1. Copy to clipboard and remove temp file:
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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
