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 | $0.00144 | $0.01409 |
| Opus 5.5 | $0.00058 | $0.00564 |
| Sonnet 5.5 | $0.00029 | $0.00282 |
| Haiku 4.5 | $0.00014 | $0.00141 |
Grade A, and why
sound-check 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sound check
Everything in Live fails loudly except silence. A wrong note errors, a bad index errors, a missing file errors — but a track that makes no sound reports nothing at all. It writes clean, it places clean, it renders clean, and the only trace is a band that reads 0.0% in an analysis you might not run until the arrangement is finished.
So check before you build. Thirty seconds here saves rebuilding an arrangement.
When
- After loading instruments and writing the first session clips — before
place_in_arrangement. - After loading any drum rack, always.
- Whenever the user says something is missing, thin, or inaudible.
- Whenever a
record_masterband reads near zero where you expected content.
The check
1. Drum racks: read the pads, don't trust the map.
get_drum_map returns Live's standard mapping. get_drum_pads(track, device)
returns what the loaded rack actually fills. They are not the same — factory
kits routinely cover only 36–51, so the shaker at 70 is silence. Write only
notes the rack lists; if you want 16th shakers and there is no shaker pad, use
the closed hat at low velocity instead.
2. One measured pass over every track.
Fire nothing. Place a few bars, then:
measure_tracks(track_indices=[0,1,2,…], start_bar=<a bar where all of them play>, seconds=15)
One playback pass, ranked by peak, silent flagged under 0.02. Pass
start_bar — without it you measure wherever the playhead sits, and a playhead
parked outside the section reads 0.000 on every track, which looks exactly
like a broken set.
3. Read the ranking as a mix, not just a checklist.
For four-on-the-floor: kick on top, bass under it, lead below that, then percussion, then pads. If the ranking is upside down you have found a mix problem before writing 176 bars over it.
A track reads silent — the decision tree
Never raise the fader first. Work down this list:
| check | how | fix |
|---|---|---|
| Is there an instrument? | list_track_devices |
MIDI track with only effects makes no sound |
| Is it a drum note that exists? | get_drum_pads |
rewrite the pattern onto filled pads |
| Was a session clip ever fired? | — | back_to_arranger |
| Is the track muted, or another soloed? | get_song_status |
unmute |
| Does the section actually contain the clip? | get_arrangement_clips |
you measured the wrong bar |
| Is the filter shut? | list_device_parameters |
see the cutoff floors in the hellyee skill |
| Genuinely quiet, not silent? | solo + record_master 4 bars |
now a level problem — see below |
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.

sound-check is a skill published in the GitHub repository guvense/hellyee (9 stars, last pushed 2mo ago), licensed MIT. It adds 144 tokens to every session and 1,409 once invoked, about $0.0006 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 2026-08-31.
