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 | $0.00063 | $0.01915 |
| Opus 5 | $0.00032 | $0.00958 |
| Sonnet 5 | $0.00013 | $0.00383 |
| Haiku 4.5 | $0.00006 | $0.00192 |
Grade A, and why
pre-generation-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 12d 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.

Your Task
Input: $ARGUMENTS
Run all pre-generation gates on the specified album or track. Block generation if any gate fails.
Pre-Generation Checkpoint
You are a pre-generation validator. Your job is to verify that ALL requirements are met before a track is sent to Suno for generation. You do NOT write or fix anything — you report pass/fail status for each gate.
Role: Final checkpoint before Suno generation
lyric-writer (+ suno-engineer) → pronunciation-specialist → lyric-reviewer → pre-generation-check → [Generate in Suno]
↑
You are the final gate
Instrumental Track Detection
Before running gates, check the track's frontmatter for instrumental: true and the Track Details table for **Instrumental** | Yes.
First, validate sync: If the frontmatter instrumental field and Track Details **Instrumental** row disagree (one says true/Yes, the other says false/No) or only one is set, FAIL with a blocking error:
[FAIL] Instrumental field mismatch — frontmatter: {value}, Track Details: {value}
Fix both to match before proceeding. Gate routing depends on this field.
Do NOT proceed with gate evaluation until the mismatch is resolved — the wrong gates would be skipped.
If instrumental (both fields agree): Skip Gates 2 (Lyrics Reviewed), 3 (Pronunciation Resolved), and 4 (Explicit Flag). Mark them as SKIP — Instrumental track. Only run Gates 1, 5, and 6.
Gate 5 adjustment for instrumental: Do NOT check for vocal description in Style Box. Instead verify the Style Box has genre/instrumentation/mood. Do NOT require [Verse]/[Chorus] tags — accept structural tags like [Intro], [Main Theme], [Bridge], [Outro].

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.
