Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.00377 |
| Opus 5 | $0.00024 | $0.00188 |
| Sonnet 5 | $0.00010 | $0.00075 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
txt-copy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Copy Text to Clipboard
Copy generated text content to clipboard via a timestamped temp file.
Activation Triggers
- "copy this", "copy to clipboard", "save to clipboard"
- "copy the email", "copy the message", "copy the letter"
- After generating text content when user indicates they want to use it
- "I need to paste this", "put it in clipboard"
Workflow
-
Identify the text content to copy (from recent generation or user-specified)
-
Write to timestamped temp file:
tmpfile="/tmp/claude-txt-copy-$(date +%s).txt"
cat > "$tmpfile" << 'EOF'
<content here>
EOF
- Copy to clipboard and remove temp file:
if [[ "$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"
- Confirm to user: "Copied to clipboard (N characters)"
Notes
- Use
catwith 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.

txt-copy is a skill published in the GitHub repository umputun/cc-thingz (470 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 377 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
flow-next-guide
Recommend the smallest sufficient flow-next workflow from the starting state. Stateless router. Use when unsure which command or stage applies next.
sitrep
Situational awareness — where am I, what was I doing, what's next. Context recovery after compression, confusion, or mid-session reorientation.
caveman
Ultra-compressed mode — 65-75% fewer tokens, preserving technical accuracy. Strips filler, hedging, pleasantries. Code/commits stay in normal language.
krux-flow
Use when the user wants iterative one-step-at-a-time execution, approval before each move, no upfront plan. Triggers on "włącz flow", "wyłącz flow".
krux-konkret
Use when the user wants strict scope precision, only what's asked, nothing more. Triggers on "włącz konkret", "wyłącz konkret".
plugin
Manage Claude Code plugins — add marketplaces, install, update, remove, list. Use when installing plugins, checking status, or managing the registry.
