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.

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 | $0.00059 | $0.01122 |
| Opus 5 | $0.00030 | $0.00561 |
| Sonnet 5 | $0.00012 | $0.00224 |
| Haiku 4.5 | $0.00006 | $0.00112 |
Grade A, and why
chord-pro 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 11d 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chord Pro
Generate or refine chord progressions with proper voicing. Music-theory grounded — no random Reddit-tier chord stacks.
Workflow
1. Ask if needed
Required: key + mode, mood/genre, target instrument. Optional: length (default 4 chords), tempo (for rhythmic feel).
If two are missing, ask in one sentence:
"What key and what mood?"
2. Choose progression by genre/mood
| Mood/Genre | Reliable progressions (in C / Cm) |
|---|---|
| Sad / cinematic | Cm – Ab – Eb – Bb (i-VI-III-VII), or Cm – Gm/Bb – Ab – Eb |
| Hopeful / pop | C – G – Am – F (I-V-vi-IV), or C – Am – F – G |
| Tension | Cm – F – Cm – G7 (i-iv-i-V), or Cm – Bb – Ab – G |
| Neo-soul / R&B | Cmaj7 – Em7 – Am7 – Dm7 (I7-iii7-vi7-ii7), or use modal interchange |
| Lo-fi / chill | Cmaj7 – Fmaj7 – Bb7 – Eb7 (mixolydian feel), or use ii-V-I in jazz extensions |
| Cinematic build | Cm – Ab – Fm – G (Aeolian + V) |
| EDM uplifting | Am – F – C – G (vi-IV-I-V — the "Axis") |
| Modal/dorian | Cm – F – Gm – Cm (i-IV-v-i in dorian) |
3. Voice properly
For each chord, place voices according to instrument:
Piano (most common)
- LH: Root + 5th (or root + octave) below middle C
- RH: 3rd + 7th (or 3rd + 5th + 9th for color) above middle C
- No closed-position triads in the same octave as the bass
String ensemble
- Cello: root (one octave below middle C)
- Viola: 5th (or 3rd in inversion)
- Vln 2: 3rd or 7th (depending on chord quality)
- Vln 1: highest color tone (9, 11, 13)
- Respect ranges: Vln1 G3-G6, Vln2 G3-D6, Vla C3-A5, Cello C2-C5
Guitar
- Use idiomatic guitar voicings, not piano-translated chords
- Open chords for folk/indie
- Drop-2 voicings for jazz
- Power chords (root + 5th) for rock
Pad / synth
- Spread across 2 octaves
- Can use closed voicing in upper register for warmth
- Avoid the muddy zone (root in same octave as bass synth)
4. Add color (optional)
If user wants "more color":
- Add 9ths to major chords (Cmaj9 instead of C)
- Add 11ths to suspended chords
- Use 7ths consistently in jazz/neo-soul
- Add altered tones (b9, #11) on V chords for tension
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.
- 11d ago First seen · 99 lines · 59 tokens per session scan A 3baa1e533d99
chord-pro is a skill published in the GitHub repository glincker/ableton-skills (25 stars, last pushed 17d ago), licensed MIT. It adds 59 tokens to every session and 1,122 once invoked, about $0.0003 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.
