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 | $0.00017 | $0.00924 |
| Opus 5 | $0.00009 | $0.00462 |
| Sonnet 5 | $0.00003 | $0.00185 |
| Haiku 4.5 | $0.00002 | $0.00092 |
Grade A, and why
ctthandoff scanned grade A with 1 finding 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s -X POST http://localhost:8129/api/audio/speak \ What it actually says
Arguments: $ARGUMENTS
- If the user types
/handoff quiet, skip audio playback and only copy to clipboard - If no arguments (empty), play audio after copying
Generate a concise handoff summary of our conversation that I can use to continue in a new Claude Code session.
Use this exact format:
## What we're working on
- [Primary task/topic]
- [Secondary items if applicable]
## Current state
- [Where we left off]
- [Any pending questions or decisions]
## Key decisions made
- [Important choices/conclusions from this conversation]
## Recent changes
- [Files modified, if any]
- [Commands run or actions taken]
## Important context
- [Facts, preferences, or constraints I mentioned]
- [Technical details that matter for continuing]
## Next steps
- [Immediate next action]
- [Follow-up tasks]
Requirements:
- Be concise but complete - capture what's needed to continue without re-explaining
- Focus on actionable state, not conversation history
- Include file paths and technical specifics where relevant
- Skip sections that don't apply (e.g., "Recent changes" if no files were modified)
After generating the summary, copy it to clipboard using this bash command:
# Detect environment and copy accordingly
if command -v clip.exe &> /dev/null; then
# WSL with Windows clipboard
cat <<'HANDOFF_EOF' | clip.exe
[INSERT THE GENERATED HANDOFF SUMMARY HERE]
HANDOFF_EOF
echo "Handoff copied to clipboard (WSL/Windows)"
elif command -v xclip &> /dev/null; then
# Linux with xclip
cat <<'HANDOFF_EOF' | xclip -selection clipboard -i &>/dev/null &
[INSERT THE GENERATED HANDOFF SUMMARY HERE]
HANDOFF_EOF
sleep 0.2
echo "Handoff copied to clipboard (xclip)"
elif command -v xsel &> /dev/null; then
# Linux with xsel
cat <<'HANDOFF_EOF' | xsel --clipboard --input
[INSERT THE GENERATED HANDOFF SUMMARY HERE]
HANDOFF_EOF
echo "Handoff copied to clipboard (xsel)"
elif command -v wl-copy &> /dev/null; then
# Wayland
cat <<'HANDOFF_EOF' | wl-copy
[INSERT THE GENERATED HANDOFF SUMMARY HERE]
HANDOFF_EOF
echo "Handoff copied to clipboard (Wayland)"
else
echo "No clipboard tool found. Manual copy required."
echo ""
cat <<'HANDOFF_EOF'
[INSERT THE GENERATED HANDOFF SUMMARY HERE]
HANDOFF_EOF
fi
Then display:
Handoff summary copied to clipboard!
To continue in a new session:
1. Start new Claude Code session: claude
2. Paste the handoff (Ctrl+V or Ctrl+Shift+V)
3. Add your next question/task after the handoff
Audio Playback via Tabz
Check $ARGUMENTS first:
- If
$ARGUMENTScontains "quiet" -> Skip audio entirely - If
$ARGUMENTSis empty or doesn't contain "quiet" -> Play audio via Tabz TTS
When playing audio, use the Tabz backend TTS endpoint (plays through browser, not Windows):
curl -s -X POST http://localhost:8129/api/audio/speak \
-H "Content-Type: application/json" \
-d '{
"text": "[INSERT PLAIN TEXT VERSION OF SUMMARY - no markdown, conversational]",
"voice": "en-GB-SoniaNeural",
"rate": "+20%",
"volume": 0.8
}' > /dev/null 2>&1 &
IMPORTANT:
- Run the curl command in background (with
&) so it doesn't block - Convert the summary to plain spoken text (no markdown formatting, bullet points become natural speech)
- Keep it concise for audio - summarize the summary if needed (aim for 30-60 seconds of speech)
After triggering playback, tell the user: "Audio summary playing through Tabz!"
If quiet mode, just confirm: "Handoff copied to clipboard (audio skipped)"
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.

ctthandoff is a command published in the GitHub repository GGPrompts/TabzChrome (146 stars, last pushed 14d ago), licensed MIT. It adds 17 tokens to every session and 924 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
