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 | $0.00086 | $0.00790 |
| Opus 5.5 | $0.00034 | $0.00316 |
| Sonnet 5.5 | $0.00017 | $0.00158 |
| Haiku 4.5 | $0.00009 | $0.00079 |
Grade A, and why
riff-setup 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Riff Setup
Set up Riff for hands-free interaction with AI agents and apps. Riff has two independent components that can be installed separately or together:
- Riff Bridge - Maps a JX-11 Bluetooth smart ring to keyboard events (voice recording toggle, send, delete, scroll, interrupt)
- Riff Voice - Speaks AI agent output aloud using on-device TTS (Kokoro via MLX on Apple Silicon)
Setup Workflow
1. Determine which components to install
Ask the user which components they want:
- Riff Bridge only - Control AI agents or any app by voice using the smart ring. Read output on screen.
- Riff Voice only - Type normally at the desk. Hear AI agent output spoken aloud.
- Both - Full hands-free loop: speak via ring, hear responses via Riff Voice.
If unclear, recommend starting with Riff Bridge - it's the core hands-free experience.
2. Check prerequisites
Read references/setup-guide.md for the full prerequisite checklist per component. Verify each prerequisite before proceeding. Key checks:
Riff Bridge: Verify swiftc --version works, confirm JX-11 ring is paired in Bluetooth settings, confirm user has a voice-to-text app installed.
Riff Voice: Verify uname -m returns arm64 (Apple Silicon required), verify Python 3.10+, verify uv is installed.
3. Install the selected components
Follow the step-by-step installation in references/setup-guide.md. Run the commands and verify each step before proceeding to the next.
For Riff Bridge:
cd riff-bridge
make all && make install
Then guide the user through granting Input Monitoring and Accessibility permissions.
For Riff Voice:
cd riff-voice
make install
Then verify with riff-say "Riff Voice is working".
4. Configure key mappings (Riff Bridge)
After installation, ask the user:
- Which voice-to-text app they use
- What keyboard shortcut their app uses for push-to-talk
If their app's shortcut differs from Option key (the default), modify riff_bridge.swift to match. See references/setup-guide.md for the constants to change and common macOS virtual keycodes.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

riff-setup is a skill published in the GitHub repository remotehumans/riff (26 stars, last pushed 2mo ago), licensed MIT. It adds 86 tokens to every session and 790 once invoked, about $0.0003 per session on Opus 5.5. 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.
