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 | $0.00403 | $0.00403 |
| Opus 5.5 | $0.00161 | $0.00161 |
| Sonnet 5.5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade A, and why
riff CLAUDE.md 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 2mo 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
Riff
Monorepo for hands-free AI interaction — smart ring input and voice narrator.
Components
riff-bridge
macOS daemon that bridges a JX-11 smart ring (BLE HID) to keyboard events for hands-free voice interaction.
- Tap: Toggle Left Option key (voice-to-text push-to-talk)
- Swipe right: Enter key (submit messages)
- Swipe left: Backspace/Delete
Uses IOKit HID Manager for device-specific detection (VendorID/ProductID) and CGEvent tap to block default media key behavior.
riff-voice
Voice narrator daemon that speaks AI agent output aloud using MLX-Audio Kokoro TTS.
- FIFO queue: Multiple sessions send text, one voice at a time
- Per-agent voices: 54 Kokoro presets mapped by project directory
- Session announcements: "project-name says:" before each message
- Interrupt support: Stop speech instantly via
riff-ctl interruptor ring Escape button - Speed control: Adjustable playback speed (0.5-3.0x) via
riff-ctl speed
Socket protocol over /tmp/riff.sock. Claude Code Stop hook auto-sends summaries.

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.
