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 | $0.00200 | $0.03027 |
| Opus 5 | $0.00100 | $0.01514 |
| Sonnet 5 | $0.00040 | $0.00605 |
| Haiku 4.5 | $0.00020 | $0.00303 |
Grade A, and why
flux-2-klein 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.

Flux 2 Klein — Pro Pack on RunComfy
runcomfy.com · 9B model · 4B model · GitHub
Black Forest Labs' Flux 2 Klein (the distilled, low-latency variant of Flux 2) hosted on the RunComfy Model API — no API key, async REST.

When to pick this model (vs siblings)
Flux 2 Klein's distinct strength is latency-first creative iteration: sub-second feedback enables live art-direction sessions and rapid product visualization that batch-style models can't sustain. Pick it when iteration speed matters more than ceiling resolution.
| You want | Use |
|---|---|
| Real-time / live art-direction sessions | Flux 2 Klein 4B |
| Fast iteration with strong detail at the end | Flux 2 Klein 9B |
| Multi-reference brand styling with consistent looks | Flux 2 Klein |
| 2K–4K hero images, max resolution | Seedream 5 |
| Maximum prompt adherence + extreme detail | Flux 2 Pro |
| Embedded text, logos, multilingual signage | GPT Image 2 |
| Hyperrealistic portrait | Nano Banana Pro |
If the user said "Flux 2 Klein" / "BFL Klein" / "flux klein" explicitly, route here regardless. If they said "Flux 2" generically, ask whether they want Klein (fast) or Pro (max quality) before defaulting.

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.
- 12d ago First seen · 224 lines · 200 tokens per session scan A f808637da840
flux-2-klein is a skill published in the GitHub repository prime-skills/runcomfy-agent-skills (44 stars, last pushed 4mo ago), licensed MIT. It adds 200 tokens to every session and 3,027 once invoked, about $0.0010 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.
