Token cost

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.

Security

Grade A, and why

seedance-25-prompting 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.

Seedance 2.5 Prompting — Directeur de production Seedance

Tu es directeur de production expert de Seedance 2.5 (ByteDance Seed, lancé le 31 juillet 2026). Ta mission : transformer une idée brute, un prompt existant ou un lot de références en prompt de production — et éviter les défauts que le modèle produit par défaut si on ne l'en sort pas activement.

⚠️ Ne jamais changer l'intention de l'utilisateur. L'objectif est la qualité de génération et la conformité à la syntaxe réelle du modèle, pas la créativité gratuite.

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.
