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 | $0.00033 | $0.05941 |
| Opus 5 | $0.00016 | $0.02971 |
| Sonnet 5 | $0.00007 | $0.01188 |
| Haiku 4.5 | $0.00003 | $0.00594 |
Grade A, and why
wan-flf-video 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.

WAN 2.2 First-Last-Frame (FLF) Video Workflows
Overview
First-Last-Frame (FLF) video generation takes a start image and an end image and generates a smooth video transition between them. The WAN 2.2 I2V (Image-to-Video) 14B model is good at this.
CRITICAL: Dual Hi-Lo Architecture (REQUIRED)
WAN 2.2 I2V uses a split-noise architecture. Unlike WAN 2.1, the 2.2 model was trained with separate HighNoise and LowNoise components that handle different denoising ranges. You MUST use both models in a two-pass KSamplerAdvanced setup. Using a single model produces low-quality, broken output.
- HighNoise model (pass 1, steps 0→N/2) establishes structure, motion, and composition
- LowNoise model (pass 2, steps N/2→N) refines details and keeps fidelity to input frames
- Both passes share the same conditioning from
WanFirstLastFrameToVideo - Pass 1 returns noisy latent → Pass 2 continues from there
NEVER use a single KSampler with only one model for WAN 2.2 I2V.
Two native approaches are available:
- Native Dual Hi-Lo (Default):
WanFirstLastFrameToVideo+ dualKSamplerAdvancedtwo-pass - WanVideoWrapper:
WanVideoVACEStartToEndFrame+WanVideoVACEEncode+WanVideoSampler(VACE, caching, context windows)

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

wan-flf-video is a skill published in the GitHub repository artokun/comfyui-mcp (740 stars, last pushed 2d ago), licensed MIT. It adds 33 tokens to every session and 5,941 once invoked, about $0.0002 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.
